1. Introduction
It’s often thought that certain careers, such as working for a charity or becoming a
surgeon, are ethical because they ‘make a difference.’ Suppose, for example, that a
surgeon performs 100 lifesaving operations per year. Intuitively the difference she
makes is that she saves 100 lives per year. But there’s a counterargument to this
claim. If you don’t take these jobs, someone else will. Let’s introduce a technical
term:
Replaceable
If there’s a job that someone else would take if you don’t take it, then in that
job, you’re replaceable.
If the person who would replace you would do the job just as well as you would
have done, then at a first glance you make no difference at all. The surgeon’s
lifesaving operations will still be performed.
How, then, are we to understand the consequences of taking a career in which one is
replaceable? Almost 200,000 graduates1 enter the workforce each year in the UK, and
a majority take ethical considerations into account in choosing their career2. For these
people whose career choice is ethically motivated, this question is deeply important.
One can have a huge direct impact through many careers. A heart surgeon might be
able to perform more than one hundred lifesaving operations per year. A fundraiser
who raises $1m for the Against Malaria Foundation would enable 200,000 people to
(HESA, 2011)
In a survey by The Guardian, over 70% of students said that ethical considerations were
crucial in choosing an employer. See (Robinson, 2006)

receive mosquito nets. As I explore in the first part of this thesis, how one analyses
replaceability could therefore mean the difference between saving hundreds of lives
and saving none.
In the second part, I argue that making a difference is not only morally relevant, but
that the job-related consequences of career decisions determine which career choice is
most ethically preferable. I call this the Dominance Thesis:
Dominance Thesis
For typical ethically motivated career decisions, the job-related consequences
of the decision typically determines which choice is ethically preferable.
I define:
Job-related consequences
The consequences that result from the activities of people in jobs, which they
perform as part of the job.
Since replaceability determines the job-related consequences of careers, it determines
which choice is ethically preferable, so is a crucial consideration for those who are
pursing ethical careers.
One might find this surprising. Replaceability in career choice was first introduced
by Bernard Williams in Utilitarianism: For and Against3 precisely to show that not
only the consequences of career decisions are morally relevant. In Williams example,
3
(Williams & Smart, 1973) pp97
4
George is offered a job at a chemical weapons factory. He is told that if he doesn t
take the job, a more zealous person will. In that job, George is replaceable. Williams
believes that George has reason to not take the job, even if taking the job would have
positive consequences (since George would do less harm than the zealous man).
Williams gives the second example of Jim and the Indians. Jim is told that if he kills
one Indian in a group of twenty, the other nineteen will be let free. If he doesn t kill
one Indian, Pedro will kill all twenty. So, for whichever Indian Jim kills, if he doesn t
kill them, someone else will. Jim s act of killing the Indian is replaceable. This shows
that actions of all kinds can be replaceable, raising similar dilemmas.
Replaceable Actions
Of an action, if it’s the case that an agent doesn’t perform that action,
someone else will, then that action is replaceable for that agent.
Williams is primarily concerned with whether consequentialism can explain the
intuition that Jim has reason to not kill the single Indian, even though it leads to
much better consequences. This is not the concern of this thesis. I m concerned with
the normative question of what we should do in typical career decisions. Even if
Williams is correct that George shouldn t take the job at the chemical weapons
factory, I argue that in typical cases of ethically motivated career choice,
consequences determine ethical preferability, making replaceability a crucial
consideration.
5
Despite its importance, replaceability is ignored in what s called ethical careers
advice by career choice guides and university careers services. This is shame. Each
year, thousands of people enter the workforce wanting to make a difference but
they are not given the advice they need. You can t know that you re making a
difference without the relevant facts about replaceability.
The ethics of career choice is also neglected in practical ethics.4 This is also shame.
We’ll spend over 80,000 hours in our careers, and career decisions are some of the
most important we make. Practical ethics should be able to offer guidance in these
decisions. Beyond Williams, who was not concerned with the normative question of
which career to take, there’s only one paper which mentions replaceability in career
choice5. This paper, by Will Crouch6, is not directly about replaceability, but rather
makes an application of it. For this reason, I simultaneously present the first
systematic exploration of the ethical issues raised by replaceability in career choice.
Outline
In the first part, I explore how we should think about the morally relevant
consequences of career decisions in the light of replaceability. In §2, I introduce the
Naïve View, which states that what’s morally relevant about the consequences of
one’s actions is what one does directly. This means ignoring replaceability. I reject
this view, arguing that what would have happened if one hadn’t taken the career is
The existing recent literature focuses on the question of whether it s permissible to take a
non-altruistic career e.g. see (Buss, 2006) and (Care, 1984), as well as small debate about
whether many professionals should retire immediately e.g. (Lenman, 2007)
5 A similar point is also made in print in (Tomasik, 2007)
6 (Crouch, Unpublished)

also morally relevant – the Counterfactual View. In §3, I introduce a Simple Analysis of
the relevant counterfactual, which states that the consequences of a career decision
depend on the difference between what one does in a career and what one’s
replacement would have done. This is the view adopted by Williams and used by
Crouch, but it turns out to be too simple. In §4, I introduce for the first time a
Sophisticated Analysis of the counterfactual. I explore what this analysis means for the
consequences of typical career decisions.
In the second part, I defend the moral relevance of replaceability, understood as
modifying the consequences of career decisions according to the Sophisticated
Analysis. In particular, I argue for the Dominance Thesis. In §5, I consider the other
consequences of career decisions, such as signalling effects. In §6, I consider nonconsequentialist considerations, in particular Side Constraints, Virtue and Integrity. I
show that none of these considerations gives us reason to ignore replaceability in
general. In §7, I consider the general objection that taking account of replaceability in
career choice is analogous to making the bad argument that ‘if I don’t buy this meat,
someone else will, so it’s permissible to buy it.’ I show that it’s not analogous.
Moreover, in cases where it is analogous, like ethical investing, it shows that we
should rethink our views about these cases. This means replaceability should be a
crucial consideration in all ethically motivated career choices.

Part 1 – The Consequences of Career Decisions
2. The Naïve View
2.1. Introduction
Let’s consider an example career decision.
Sarah the Surgeon
Sarah, during med school, decides to become a surgeon. She successfully
applies to the surgery speciality, succeeding against several other applicants.
Over the course of her career, she goes on to perform 100 lifesaving
operations per year.
Intuitively, one might think that the consequences of Sarah becoming a surgeon are
saving 100 lives per year. But if Sarah didn’t become a surgeon, suppose one of the
other applicants would have been offered the place. So Sarah is replaceable. Sarah’s
replacement would still perform many of the operations that Sarah performs.
One might ignore this fact, because one believes that what s morally relevant is what
Sarah does directly as the result of her decision. I call this the Naïve View of
consequences:
Naïve View
The morally relevant aspect of the consequences of taking a career is what
one does directly in that career.
There are two components to the meaning of doing directly :
8
1. Non-Counterfactual Cause: The agent is part of the causal chain that leads to the
result, though the result might still happen if she didn t act7
2. Proximity: The agent is reasonably close in the causal chain to the result and
her level of responsibility diminishes with distance from the result
Sarah is both part of the causal chain the leads to the 100 saved lives, and since she
performs the operations with her own hands, is close to the end result. So, on this
view the consequences of her actions include saving these lives.
A stricter interpretation requires that the agent is the final agent in the causal chain.
The surgeon is indeed the final agent, but this interpretation is too strict. The bankers
who contributed to the suffering of the financial crisis (supposing there were some)
only did so through a complex causal chain. They were not the final agents in
causing the suffering, but it was a consequence of their decisions.
A more plausible and common position is that relevance diminishes with distance
from the result. No-one would pretend that someone who fundraises to pay for more
nurses is not doing any good. Nevertheless, it does seem to be considered especially
praiseworthy to be the nurse instead of the fundraiser – directly helping people with
one s own hands.
Note this condition might not be compatible with certain counterfactual accounts of
causation. These accounts, e.g. as developed in (Lewis, 1973), require that for c to cause e, if c
doesn t occur, then e would not occur.
7
9
The Naïve View seems to be implicit in much ethical careers advice, which focuses
on jobs that directly do good and ignores replaceability. Paradigm ethical careers are
those in the 3rd sector8, in which one is directly involved with the activities of
altruistic non-profit organisations. They commonly extend to certain public sector
jobs, like social work and being a state school teacher, which involve directly helping
disadvantaged people. There s little discussion of how one might do good indirectly,
for instance through philanthropy or by saving the time of someone who is doing a
lot of good. Completing Norman Borlaug s9 chores would not normally be
considered an ethical career, but speeding up his research by just a week could have
meant that thousands of additional lives were saved by his short-stem diseaseresistant wheat.
2.2. The Counterfactual View
Despite being implicit in much ethical careers advice, the Naïve View isn t a good
reflection of what we normally mean by the consequences of a decision. Rather,
consequences consist in making a difference. Making a difference means bringing
about states of affairs that wouldn t have happened otherwise. Accepting this means
taking a Counterfactual View of consequences:
Counterfactual View
The morally relevant aspect of the consequences of taking a career is the
This is clearly the case, for example, in (Burrows, 2006) and in the many on-line ethical
careers websites.
9 Sometimes credited with saving one billion lives (Easterbrook, 1997)

10
difference between what happened because of you and what would have
happened otherwise.
The consequences that are morally relevant according to the Counterfactual View are
therefore the counterfactual consequences:
C-Consequences
The c-consequences (counterfactual consequences) of an action are the
differences between what happened because of that action and what would
have happened otherwise.
In Lewis possible worlds semantics, one could understand what would have
happened otherwise as what happens in the closest possible in which one doesn t
take the job.
Adopting the Counterfactual View means rejecting both parts of the Naïve View.
Despite this, ‘to make a difference’ is one of the most commonly cited reasons to take
an ethical career! So, both views exist in tension in ethical careers advice.
I think this is in part genuine inconsistency. Counterfactuals are often ignored. For
instance, Nassim Taleb10 has argued that we also fail to take account of how
successful people are often not successful in close counterfactual situations when
assessing their success, in particular due to Hindsight Bias. I think it’s also the result
of a false belief that careers which do a lot good directly are also those that make a
difference. I show this is often not the case in §4.
10
(Taleb, 2007)
11
Whatever one believes about the meaning of ‘consequence’, the Counterfactual View
needs some weight i.e. the c-consequences of decisions have at least some moral
relevance. To see that, consider:
Paul and the Paramedics
Paul is involved in a car crash. When he regains consciousness, he finds his
mother lying next to him, seriously injured. Paramedics have just arrived.
Paul pushes the paramedics out of the way, and performs life-saving first aid
on his mother. Unfortunately, he’s much less skilled than the paramedics, so
causes her permanent spine damage, resulting in paralysis. If Paul hadn’t
acted, the paramedics would have performed the lifesaving first aid, and his
mother would have fully recovered.
Paul s direct action is to save his mother s life. So, according to the Naïve View, the
consequence of his action is to save his mother s life, so his action was morally
commendable. But it s clearly natural to say that the consequence of Paul pushing
the paramedics out of the way is to paralyse his mother. Moreover, this cconsequence is highly morally relevant, and explains why his action was wrong. So,
the Counterfactual View must be assigned some weight.
2.3. The Relevance of the Counterfactual View
Accepting that c-consequences are morally relevant means that replaceability is
morally relevant. Indeed, we can image analogous career decision cases. If Paul takes
12
a job instead of someone who would do much more good in that job, then it also has
negative c-consequences.
Nevertheless, this example doesn t show how and which c-consequences are morally
relevant. One might believe that factors over and above c-consequences are
important. For instance, some actions might be wrong in themselves, irrespective of
consequences. One might also retain Proximity, i.e. apply greater moral weight to
consequences that are caused by the agent and result from a shorter causal chain.
This implies partially neglecting replaceability.
Proximity is intuitive in that we often act as if indirect ways of bringing about
positive c-consequences are less praiseworthy than direct ways. Even if a fundraiser
raises enough money to employ nurses to hand out medicine that save 100 lives, we
would often find the nurse who saves 100 lives more praiseworthy (assuming both
wouldn t have happened otherwise . This could be due to other factors. Perhaps
being the nurse is considered more demanding, even if not ethically preferable.
Praising the nurse might instead simply be inconsistent with our beliefs about ethical
preferability. Overweighting the relevance direct actions might be a useful heuristic.
In general it s easier to attribute causality in these cases, thus these consequences are
usually more certain. This causes us to mistakenly apply higher weight to close
consequences, even when we know the consequences precisely. Fully considered,
13
however, what s important is that the lives get saved. Both the fundraiser and the
nurse are necessary to save the lives, so both are equally praiseworthy.
Indeed, as we would expect if this were the case, judgements of Proximity often have
an air of arbitrariness. An effort to save lives with a malaria vaccine requires
everyone from people who distribute the vaccine to those who discovered it, to those
who campaigned for research funding. It s odd to say the campaigners are less
praiseworthy than the researchers because they are one further step removed in the
causal chain from the saved lives. It would be even odder to encourage the
researchers to become nurses in order to do good more directly.
When it comes to harmful careers, Proximity matters because if one directly causes
harm, that action could be prohibited by a side constraint or it could compromise
one s integrity. So, although it s implausible that Proximity matters in itself, it often
matters due to non-consequentialist considerations. These are covered in §6.
Supposing we apply weight to the Counterfactual View, we still need to ask, what are
the c-consequences of typical career decisions? In the next section I introduce the
Simple Analysis of the counterfactuals, as employed by Williams and Crouch. In §4 I
show that a more complex analysis is needed.
14
3. The Simple Analysis of Replaceability
3.1. The Replaceability Ratio
What would happen if someone doesn’t take a job depends on the details of the
situation. So, the impact of replaceability varies between choices as well as between
different analyses. To characterise different answers, I introduce the Replaceability
Ratio:
Replaceability Ratio, R
The ratio between the value of the job-related c-consequences of taking a job,
taking into account the fact that one is replaceable, and the positive value one
produces directly in that job.
‘Value produced directly’ is intended to be understood as all the good one causes in
the job as a result of the activities of the job, whether or not it would have happened
otherwise. So if Sarah were not replaceable, and none of those operations would
have been performed, R=1. If all of the operations would have been successfully
performed anyway, R=0. Adopting the Naïve View, ignoring Proximity, means
always taking R=1.
3.2 The Simple Analysis of Replaceability
If Sarah doesn’t become a surgeon, someone else would: her replacement. The
Simple Analysis claims:
Simple Analysis
The c-consequences of taking a job consist of the difference between what
15
happens if one takes the job and what would have happened if one’s
replacement had taken the job.
If Sarah had chosen not to become a surgeon, then someone else would have filled
that same job. Suppose that person only performed 90 successful operations per year,
then, R=0.1.
Williams seems to take this view of replaceability. He says that if George takes the
job at the chemical weapons factory, it has positive expected c-consequences. This is
because if he doesn’t take the job, it will be filled by someone who will pursue
chemical weapons research far more zealously, leading to greater expected harm.
Crouch also makes use of this analysis, although he acknowledges in a footnote that
replacement can be more complex.11
3.3. Consequences of the Simple Analysis
The Simple Analysis is only correct in limited circumstances. Nevertheless, it implies
some surprising conclusions about the consequences of typical career decisions,
which can still stand on the Sophisticated Analysis.
3.3.1. Doing Less Good Than the Naïve View
For most jobs, there’s significantly more than one applicant per place. So, if you don’t
take the job, someone else will. In particular, it will be the person who finished
11
(Crouch, Unpublished) §2
16
second in the selection process12. If we assume that on average the selection process
sorts people into order of ability and it’s not a field in which there are huge
differences in ability, we can expect this person to just be slightly worse at the job
than you. So the difference you make is significantly less than what it looks like
you’re doing directly.
Sarah is probably an example of this kind. One would expect hospitals to be able to
differentiate good surgeons from bad ones to some degree. So, ex-ante one expects
the second best applicant to be almost as good as Sarah (though this depends on
empirical facts about typical differences in ability between surgeons). So, R would be
positive but small.
3.3.2. Doing less harm than the Naïve View
Similarly, in many harmful jobs you’ll be doing less harm than it looks like you’re
doing directly. This is due to exactly the same reasoning: if the selection process
works, the person who would replace you would be slightly worse at the job, and so
produce slightly less harm than you would have produced.
Consider a typical unethical career, like working for an arms company selling
contracts to developing world governments. The aim of the selection process will be
to choose the person who can sell the most arms for the company. So, it’s likely that
the person who just fails to get the job would sell fewer arms, thus producing less
harm than the person who gets the job.
I m assuming that this counterfactual is not under-specified, as explored in (Hare, 2011), or
unknowable in a problematic way, as explored in (Lenman J. , 2000)
12
17
3.3.3. Doing good by taking harmful jobs
In some cases, it might do good to take harmful jobs, because you do less harm than
the person who would have replaced you. This could be because doing the job well
actually makes it less harmful. Examples would be careers that are on average
harmful because they require a lot of skill, but if you have enough skill, they’re not
harmful. For instance, certain types of stock market investing jobs might produce
negative value, because most investors follow the crowd and don’t base their views
on economic fundamentals. This makes markets more volatile and less efficient.
Skilled investors, however, go against the crowd, providing capital to neglected
companies, making markets more efficient.
Or perhaps it’s because you’re ethically minded, so you seek to avoid the most
harmful activities carried out by people typically in your shoes. For example, some
arms company employees bribe foreign government officials to encourage them to
buy more arms13. It seems plausible that you could take a top job in an arms
company, but veto that practice. Perhaps that would avoid most of the harm
normally done by someone in your shoes.
In these cases, one takes a job that is harmful but has positive c-consequences, so R is
negative. The size of R depends on one’s scope to avoid harmful activities. If one
makes a harmful job less bad, -1≤R<0. If one turns a harmful job into a neutral one,
R=0. If one turns a harmful job into a value producing job, R<-1.
For instance, a BAE Systems executive was recently fined for corruption, see (Evans &
Leigh, 2010)
13
18
3.3.4. Reducing the good done by taking good jobs
The selection process is not perfect. If you secure a job instead of someone who
would be better than you, then your decision has negative c-consequences, although
it looks like you’re doing good directly. This means you’re in a situation like Paul
and the Paramedics. R is negative, but closer to zero than to -1.
Being likable and attractive can help you to succeed at interview. It’s plausible that
this often doesn’t correlate equally well with job performance. Similarly, personal
connections might give some people an advantage in the selection process unrelated
to their ability. If you’re an attractive, likable, connected person, then you might need
to be particularly alert to the possibility of getting a job over someone who would
perform better than you. If you do, then you’re reducing the good that would have
been produced. The more important the job, the worse the effect. Those taking
political careers should be particularly alert to this danger.
3.3.5. Doing more good than you appear to do
It’s possible for R>1 if your potential replacement would have been destructive,
turning a good job into a harmful job. For instance, suppose accountancy normally
produces positive value, but in the hands of a corrupt person is very harmful. If your
potential replacement would have been one of these people, then by taking the job,
the positive c-consequences are greater than what it looks like you’re doing directly.
19
3.3.6. Supporting the arguments in favour of professional philanthropy
These conclusions, using the Simple View, are used to support Crouch’s14 arguments
in favour of pursuing professional philanthropy over work in the 3rd sector.
Professional Philanthropy means pursuing a high earning career with the intention
of making large philanthropic contributions to highly cost-effective causes. Crouch
first advances the Weak Thesis:
The Weak Thesis
Typically, it’s ethically preferable to pursue professional philanthropy in a
morally innocuous career than to pursue work in the 3rd sector
Morally innocuous careers are such that there is no strong non-consequentialist reason
not to pursue that career. To support this thesis, Crouch argues that (i) a high earner
could typically pay for several 3rd sector workers, having several times as much
impact (ii) a high earner can donate to the most cost-effective charities, which are
often 10x more effective than the median, whereas a 3rd sector worker will be more
restricted in where they work. Either of these arguments is strong enough to
demonstrate the Weak Thesis. But in addition, one can argue that by becoming a 3rd
sector worker the c-consequences are less than what one appears to do directly. 3rd
sector work is typically very competitive, so if you don’t take the job, you would be
replaced. Your replacement is likely to be almost as good as you would have been.
Replaceability is also used to support Crouch’s Strong Thesis:
14
(Crouch, Unpublished)
20
The Strong Thesis
Typically, it’s ethically preferable to pursue professional philanthropy in a
moderately morally controversial career than to pursue work in the 3rd sector
Morally controversial careers are such that there is a strong non-consequentialist
reason not to pursue them. Since morally controversial careers are often very well
paid, they are also competitive. So, your replacement would be almost as good as
you, causing almost as much harm as you would have done. So, the negative cconsequences of taking morally controversial careers are much smaller than the harm
one does directly.
Moreover, one can argue that if ethically minded people take morally controversial
careers, the c-consequences are often positive. If the job offers no scope to make more
ethical decisions, then one’s replacement will be equally harmful. If the job does offer
scope to make more ethical decisions, then an ethically minded person can take these
opportunities. We would expect these opportunities not to be taken by the average
replacement, who’s less ethically motivated. So, the c-consequences are positive.
3.4. Simple Analysis Conclusions
The Simple Analysis suggests that the c-consequences of typical career decisions
diverge significantly from the good one does according to the Naïve View. R can take
any value, though is typically in the range -1 to 1. Since these c-consequences are
morally relevant, it’s important to take account of replaceability in typical career
decisions.
21
4. The Sophisticated Analysis of Replaceability
4.1 Problems with the Simple Analysis
One might feel that one shouldn’t act on the conclusions of the Simple Analysis. This
is normally due to the factors addressed in Part 2. Another reason, however, is that
the Simple Analysis seems too simple. It doesn’t take account of the complexity of
the economy. This is true. In the closest possible world in which Sarah doesn’t
become a surgeon, someone else becomes a surgeon: her replacement. But then
someone else could take the job Sarah’s replacement would have had; her replacement
is also replaced. This could happen again and again. So, in general, the world in
which Sarah doesn’t become a surgeon could differ by an entire chain of
replacements. I call this the Iteration Effect.
Iteration Effect
The closest possible world in which one doesn’t take a job will in general
differ by an entire chain of replacements.
This means the Simple Analysis isn’t a complete assessment of what would have
happened otherwise, so it doesn’t tell us full the consequences according to the
Counterfactual View.15
In fact, the Simple Analysis can give results that are arbitrarily wrong. For instance, if
George takes the job at the chemical weapons factory, he prevents the zealous man
from taking the job. But if the zealous man goes on to take an even more harmful job
at another factory, then George has had a negative effect. Williams neglects to note
this additional complication, since it doesn’t affect his basic point. For someone
15
Although it might be approximately correct for someone who accepts Proximity (§2.1).
22
interested in the ethics of career choice, however, this is another c-consequence of
most career decisions.
Crouch also neglects the Iteration Effect. I will show that replaceability only does the
work Crouch wants it to do (§3.3.6) given certain empirical assumptions, which
plausibly don’t hold in many situations. I will do this by introducing, for the first
time, a way to analyse the consequences of typical career decisions in the light of the
Iteration Effect.
4.2. An Example Chain
If Sarah at medical school takes up the offer to enter the surgery speciality, what
would happen? First, there were probably other applicants who met the minimum
criteria to become surgeons, but can’t get places. If Sarah takes the offer, then a
different person, call them Tiff, can’t become a surgeon. Tiff goes on to take another
job, probably in another slightly less competitive speciality, say General Practice.
Suppose that Tiff prevents Ursula from taking up her desired GP path. Ursula, who
only wanted to work as a doctor if she could be a GP, instead enters medical
research. She ends up researching malaria vaccines. Vino, who studied biology, and

Instead, she takes up a less prestigious research position. She’s the only qualified

4.3. Characterising the Chains
If someone enters a job, it causes a downwards chain of replacements. The person who
would have taken the first job has to take their second preference job. The person
who would have taken that job has to take their second preference job. And so on. If
someone leaves a job, it causes an upwards chain of replacement. In these, everyone
below the first job is able to take a job that they prefer relative to their current job.
Replacement chains can end in two ways:
1. Someone enters a no-competition job. This is job that wouldn t exist if it were
not for the person who actually fills it. In practice, these are jobs that are
created especially for someone or are jobs for which only one qualified
applicant can be identified.
2. Someone becomes unemployed, which produces job-related value of zero
It shouldn’t be thought that in general replacement chains follow a promotional
hierarchy or even jobs in the same industry. In reality, they might involve all kinds of
jobs that are completely unrelated, except that the person in the above box would
move into them if they lost their current job.
4.4. The Value Produced by Jobs
A person in a job produces a certain amount of moral value through the activities of
that job, whatever is of value according to one’s meta-ethical and ethical position. For
25
instance, if Sarah becomes a surgeon, the value she produces consists of the value of
the 100 operations she performs per year. Notice that the value produced by a job
might be completely unrelated to the salary of that job and that different people will
disagree about the value of different jobs. For someone who cares primarily about
spreading Christianity, priests presumably do work of tremendous value, despite
their low pay. For hard-line atheists, these jobs might even be harmful.
To calculate the c-consequences of Sarah’s decision in terms of value produced, one
needs to estimate the value of each person in each job for both chains and calculate
the difference.
It can be useful to break the value produced by someone in a job into two terms. One
of these terms depends on the job. I call this the opportunity* (the star denotes a
technical use of the word):
Opportunity*
The opportunity* of a job is the job’s potential to produce value.
A job’s opportunity* consists of the resources one is given control of, one’s platform
to influence others in the job, the number of people one manages and so on. The
opportunity* for a surgeon to produce value is determined by the number of
surgeries they are able to perform, the facilities they are able to use, the skills of the
supporting staff, their options to influence the running of the hospital etc.
The second term depends primarily on the person. I call this ability*.
26
Ability*
A person’s ability* is their ability to use the opportunity* of a job to produce
value.
A person’s ability* depends on their skills and their aims. Sarah’s ability* consists of
how good she is at surgery, as well as her abilities to inspire her colleagues to be
more productive, how much she contributes to the general running of the hospital
and so on.
Opportunity* is fixed by the job. Ability* is defined so that the product of
opportunity* and ability* gives the value produced by that person in that job.
In what follows, I’ll apply these ideas to suggest how to estimate the c-consequences
of certain career decisions. The Iteration Effect makes it difficult to estimate cconsequences, especially for specific decisions. Nevertheless, it is possible to make
good estimates in certain situations, especially if one considers expected cconsequences, which rest on averages.
4.5. The Leading Order Approximation
In some situations, one only needs to consider the first couple of steps in a chain. In
the limit of considering only the first job, we recover the Simple Analysis. These
situations occur when the scope for impact in the first couple of jobs is much higher
than the expected impact of the other jobs open to people in the chain. This means
we can treat the value produced by people in the other jobs as approximately zero.
27
One example would be becoming an MP in UK. To be elected into office, one must be
selected by a party to stand in a constituency. People often seek to enter politics from
other careers, like law and journalism. If they are not selected by their party of
choice, they might give up their political aims and continue working as lawyers. The
impact of the average lawyer is much less than the potential impact of an MP. So, if
one wants to calculate the value of becoming an MP, one can sometimes neglect the
value produced by one’s nearest rival in their second choice job, and all subsequent
steps in the chain.
The same could be true when considering the actions of someone with especially
large ability*. For instance, some researchers produce work of many orders of
magnitude more impact16 than the median researcher in their field. It may be
possible just to focus on the chain insofar as it involves these super talented people,
approximating all other steps as zero.
Cases of high ability* also occur when someone has much more focus on producing
value than other people in their field.
Owain the Researcher
There is a limited amount of funding for artificial intelligence (AI) research
from academic institutions. Suppose that the majority of researchers in the
field focus on developing AI without regard to the risk of dangerous AI.
Number citations is one proxy for impact, and there s evidence that citations approximately
follow a power law distribution, e.g. see (Gupta, Campanha, & Pesce, 2005)
16
28
Owain believes that dangerous AI could be extremely dangerous. He takes a
job in academia researching artificial intelligence, but unlike his colleagues,
he uses the funding to reduce the risk of dangerous AI.
If we share Owain’s assumptions about AI, then he is producing far more of value
than anyone likely to have the research funding in his place, and anyone in the
downward chain of replacements he causes. Indeed, these people might even be
producing negative value.
4.6. Isolated Industry
Often one only wants to consider one’s impact on a single industry. In this case, the
chain can be ignored as soon as it leaves the industry. Isolated industry often arises
as an approximation. If one is ethically motivated, then it’s likely that one is
considering industries that produce far more value than average. In these cases, one
can make the approximation that anyone who drops out of the industry will, on
average, enter a job that produces approximately zero value. If one also assumes that
if someone leaves the industry, then the chain of replacements doesn’t return to the
industry, one can take the chain as ending as soon as someone leaves the industry. If
one considers isolated industries, it’s often much easier to make an estimate of the
effect of replaceability. The following are some examples.
29
4.7. Case Study: Taking a Job at a Charity
4.7.1. Introduction
Crouch claims that in taking a charity job, the c-consequences are typically much
smaller than the good one appears to do directly i.e. R<<1. I investigate whether this
is true in the light of the Iteration Effect, showing that it’s only true in some
circumstances. This discussion also serves as an exploration of the c-consequences of
typical career decisions.
I’ll assume we’re not in a situation in which it’s valid to make the Leading Order
approximation e.g. considering the actions of someone with extremely high ability*,
or an extremely high opportunity* position.
Consider the following assumption:
Constant Ability*
Someone’s ability* is constant across the job they currently occupy and the job
they would move into if they weren’t able to take that job
Constant ability* is clearly a large simplification. Although there are skills which find
a wide application across many jobs, motivating the idea that some people are
generally more skilled than others, people clearly have different levels of relative
skill in different positions. Indeed, people might intentionally alter their relative skill.
When George moves to the chemical weapons factory, he aims to reduce his ability,
so as to minimise the negative value produced by the position.
30
Nevertheless, often people will move into jobs of a similar kind, so Constant Ability
could be a good approximation. We could instead assume:
Weak Constant Ability*
On average, a person’s ability* is approximately the same in the job they
currently occupy and the job they would move into if they lost that job.
If what we care about is the expected change in value due to a career decision, then we
can use assumptions based on averages.
4.7.2. Equal Ability*
Let’s consider Ella, who is considering taking a charity job. She first considers
positions that leave little scope for differences in skill; for instance, handing out fliers
or basic administrative work. It seems reasonable to think that if someone can’t get
an entry level administrative position at a charity, they will seek to fill a similar
position at another charity, or they will leave the charity sector. I’ll assume that
administrative charity jobs produce much more value than typical administrative
jobs, so take the chain to end once someone leaves the sector. So, the chain will
consist of similar jobs.
We could model this chain by assuming that everyone in the chain has equal ability*.
So, the value each person produces just depends on the position they occupy. It
doesn’t depend on differences in skill, because there’s little scope for skill. In this
model, if Ella takes a job causing a downwards chain, the effect is to shuffle people of
equal ability* along the chain. If the resulting number of jobs in the charity sector is
the same, then this has no c-consequences. So, R=0.
31
Figure 2. Shuffling people of the same ability*
Ella
Job1
Person1
Job2
Person2
Job3
Person3
If an extra job is created, the c-consequences are equal to the product of ability* and
opportunity* for the created job. So, R could have any value.
Suppose we also assume:
Declining Opportunity*
If one doesn’t get their preferred job, one moves into a job with lower or
equal opportunity*
This is often not true, because career decisions depend on more than value
producing potential. For instance, consider someone who loses their comfortable but
low-impact job, forcing them to move into a role of much higher responsibility to pay
the bills
32
Nevertheless, it seems to be true that people generally seek the job with the highest
responsibility available. So, there’s a tendency for people to move into jobs with
lower opportunity* if displaced. So, the assumption we actually make is:
Weak Declining Opportunity*
On average, if unable to take their first preference job, one will move into
another job with lower or approximately equal opportunity*.
If we make this assumption, then we expect the opportunity of the created job at the
end of the chain to be lower or approximately equal opportunity* to the job Ella
takes. So, we expect 0<R≤ 1.
Whether Ella’s application leads to job-creation depends on supply and demand for
these jobs. As shown in §5.5, Ella probably causes about half of a job to be created, so
the situation lies between job-creation and no job-creation. So, overall we expect
0<R≤1, with R closer to 0 than to 1.
4.7.3. Equal Opportunity*
Now suppose Ella takes a job at a highly meritocratic environment, like a start-up
charity. Also suppose the chain ends whenever someone leaves the organisation
(perhaps it’s exploiting a particularly effective niche). In a meritocratic environment,
one’s skill is the primary determinant of the resources one is given. So, we could
model this situation as if everyone in the chain has approximately equal
opportunity*.
33
If no job-creation occurs, Ella’s only effect is to change the level of abilities* in the
chain. Specifically, Ella is added to the chain, and the person at the bottom is
removed. So, the c-consequences of Ella taking the job are given by the difference
between Ella’s ability* and the ability* of the person at the end of the chain,
multiplied by the opportunity*.
R could then take any value; but suppose we assume:
Job Selection Efficiency
One can only displace a person of lower ability*.
Selection Efficiency is another large simplification. Someone’s ability to get a job
could significantly diverge from their ability*. This could be because of biases in the
selection process; but it’s also because the aim of most jobs is not directly to produce
value. Rather, it’s to produce profit for the company, or some other aim which need
not line up with producing what one believes is of value.
Nevertheless, it seems like there’s some correlation between someone’s general
ability in a job and their ability to produce value in that job. Further, there’s some
correlation between someone’s ability to get a job and their ability in the job. So, it
seems plausible Weak Selection Efficiency is approximately true.
Weak Selection Efficiency
On average, if one displaces someone, they’re of lower ability*.
34
Making this assumption, Ella’s ability is expected to be higher than the person at the
bottom of the chain. So, 0≤R≤1. If Ella’s ability* is significantly higher, then R is close
to one.
If job-creation occurs, then Ella simply adds to the pool, and R=1.
Averaging the two situations, R is probably close to 1.

4.7.4. Declining Opportunity* and Ability*
Finally, suppose Ella joins a hierarchical chain, perhaps at a large and established
charity. She, on average, displaces people of lower ability* than her into lower
opportunity* jobs. This amounts to assuming both Weak Selection Efficiency and
Weak Declining Opportunity*. Assuming there’s no job-creation:
1. Ella increases the ability* of the people in the chain, by knocking out the
bottom person
2. People move down, so that lower opportunity* jobs become occupied by
people of higher abilities*
The total effect depends on (i) the length of the chain (ii) the gradient of the decline in
ability* (iii) the gradient of the decline in opportunity*. The ‘gradient’ of the decline
is the amount by which ability* or opportunity* decreases with each step down the
chain.
Here are some example inputs to provide a feel for the numbers. I assume ability*
and opportunity* decline at equal gradients.

It converges because it s the difference between two converging geometric series. The rate
of convergence depends on the gradient. For a gradient of 10%, it occurs to within 2 decimal
places at length=39. For a gradient of 50%, it occurs at length=7.
17
39
Notice that the results are the same in the limit, because at the limit, the created job is
adding no value. However, for length=1, job-creation means adding a significant
positive correction to the Simple View.
I’d hypothesise that in typical situations gradients are around 5-25%, though this is
an empirical question. If this is true, then without job-creation, 0.05≤ R≤ 0.60. So, one
makes a significant difference, but it’s significantly less than what one does directly.
With job-creation, 0.51≤R≤0.95. So, one makes most of the difference it appears one
does directly. In reality, the situation will be somewhere between job-creation and no
job-creation, depending on supply-demand dynamics (§5.5).
4.8. Case Study: Does Becoming a Banker Have Negative C-Consequences?
Crouch also claims that by entering harmful careers, one does much less harm than it
appears one does directly. Let’s suppose that Ella is choosing between taking a
charity job, and working in an area of banking where positions are typically value
destroying (with negative opportunities*). Let’s assume these banking jobs are
especially harmful relative to the average job in the economy, so we can make the
Isolated Industry approximation. These assumptions are not implausible given that
the NEF has estimated that bankers on average destroy £7 of societal value for every
£1 they are paid.18 Then, what are the c-consequences of Ella taking a job in banking?
Whether one does harm depends on one’s model of how harm is caused in the
banking industry. I’ll consider three options.
18
(NEF, Dec 2009)
40
1. If harm is caused by the mere existence of banking jobs or from something that the
individual can’t change, then abilities* are roughly equal i.e. each banker has roughly
the same potential for harm. Then R=1 with job-creation and R=0 without jobcreation. In reality, Ella probably has little effect on banking wages, and thus doesn’t
increase supply of banking labour, so R≈0 (See §5.5.).
2. If the majority of the harm done depends on a subset of bankers who make terrible
decisions or engage in illegal activities, then bankers divide into two groups: (i) a
group with abilities* close to zero (perhaps producing positive value), (ii) a subset
with positive abilities* (i.e. producing negative value). Again R≈ , unless Ella can
displace one of these unethical people out of the industry. In this case Ella has a
positive impact: R<0 and perhaps much less than - . It s not clear that Selection
Efficiency applies, because these bad people are difficult to identify ex-ante, so you
can t expect to knock one out.
Nevertheless, supposing that you’re not one of these harmful bankers19, you have
some chance of knocking one out. The probability is roughly equal to the relative
frequency of these bad people in the pool.
3. If you think that harm caused correlates well with profits produced for the bank,
then some people will have negative ability* and others will have positive ability*.
It might not be possible to know. The bankers who cause financial crashes often don t
intend to do so beforehand.
19
41
Some bankers are profitable; others are not. Selection Efficiency will apply, because
banks aim to employ people who make profits20. So, we could model the situation
with declining ability* and opportunity*. If we assume everyone has positive ability*,
we can use the results from §4.7.4., remembering that R>0 means Ella is producing
negative value. What gradient is reasonable? Salary seems like a potential proxy for
opportunity*. Its size correlates well with the amount of capital controlled. It
increases by 50-100% each time someone gets promoted (see Figure 5). If we assume
someone is promoted for every 5 steps of the chain, the gradient is 10-20%. If we
assume that people at the bottom of the chain have negative ability*, and Ella has
positive ability*, then R values will increase relative to those in §4.7.4., since she s
displacing loss-making bankers. Either way, Ella is causing a significant amount of
harm,

Concluding, R could be anywhere from negative, to zero, to close to one. It depends
on how one thinks harm originates in banking.
4.9. Conclusion
Once we move to the Sophisticated Analysis, a much more complete analysis of the
counterfactual, it becomes difficult to generalise about replaceability. Many
situations will involve chaotic chains that are very difficult to model. In two
situations, however, we can develop some understanding of the chain. These are
when we can make the (i) Leading Order approximation (in the limit of chain
21
Data taken from http://www.careers-in-finance.com/ibsal.htm
43
length=1 returning to the Simple Analysis) and (ii) the Isolated Industry
approximation. In these cases typically 0≤R≤1, with values typically larger than the
Simple Analysis.
Exactly where it lies depends on empirical facts about the chain, for instance, (i)
whether job creation take place (ii) the trend in ability* (iii) the trend in opportunity*.
One can see the range of values here (some of the numbers are illustrative):
Naïve View

R
R is unbounded both below and above. Situations where R is significantly greater
than one seem rare; but could occur for the reason given in §3.3.5. They could also
occur when highly able people don’t choose jobs based on impact. For instance,
medical school applicants who fail to get a place and enter much higher impact
medical research. As shown in §4.8., by entering certain harmful careers, R could be
significantly less than -1.
44
Does entering a good industry have good job-related c-consequences? They are likely
to be somewhat less than what one appears to do directly, but still significant (R≈0.5).
In some situations, the c-consequences could be roughly neutral (R≈0). In others, one
will do most of the good one does directly (R≈1).
Does entering a harmful industry have bad job-related c-consequences? It depends
on how harm is created by the industry. Again, R is likely in the range 0-1, but for an
ethically motivated person it might well be R<0.
Since R=1 could easily mean the c-consequences have value on the order of saving
hundreds of lives, working out R for each career option is vitally important.
45
Part 2 – The Dominance Thesis
The lessons of replaceability just learned are often ignored in making career choices,
even when they are actually raised. This is odd. If one were given the option of a
value-producing career such that R=0 and another such that R=0.5, then it seems one
has good reason to choose the second. This could be because people are simply
inconsistent. But it could also be because they believe replaceability is not morally
relevant in career choice, since it’s outweighed by other considerations.
I argue that the job-related c-consequences of career decisions, as understood
according to the Sophisticated Analysis, are not only morally relevant, but typically
determine which career choice is ethically preferable. This is the Dominance Thesis. It
means replaceability is a crucial consideration for everyone whose career choice is
ethically motivated.
5. Other Consequences
5.1. Introduction
Career decisions have many c-consequences beyond the job-related c-consequences.
If these other c-consequences are typically more important or tend to counteract the
effects of replacement, then they might give reason to ignore replaceability. This
stands quite apart from non-consequentialist views (§6) and general arguments
against replaceability (§7).
46
I will argue that although these other consequences can be important, they are highly
situation dependent, so frequently don’t give reason to neglect replaceability.
Moreover, for someone pursuing an ethical career, they are often not significant. This
section will also serve as an exploration of the other consequentialist considerations
surrounding career choice.
Some of the other c-consequences of career decisions involve:
1. Signalling effects and boycotts
2. The effects on the agent s feelings and personality
3. Supply-demand effects
These favour doing good directly. For instance, even if the job-related consequences
of taking a harmful job are zero due to replaceability, it might be good to avoid
taking it in order to: (1) signal that you want social change; (2) so that you can live
with yourself and; (3) to increases the wages of this job, reducing the profits of the
company. I will go through these effects in turn, weighing them up against the size
of the job-related consequences of career decisions. But before that I will consider
another type of consequence, which typically enhances the effects replaceability.
5.2. Compensation Effects
Replaceability can be viewed as one of a species of more general compensation effects.
Most jobs are performed because a group of people want them performed – they
expect the job will create something of value to them. In the counterfactual situation
47
in which you don’t take the job, this demand still exists. So, efforts will be made to
bring about the value that you would have created: to compensate for your absence.
The most obvious effort is hiring someone else to do the job – replacement. But
compensation effects can take other forms. One of the most important is reallocation of
tasks.
Reallocation of Tasks
The process of reassigning the tasks performed by different jobs in order to
maximise effectiveness
Consider:
NHS Budget Cuts
Suppose the NHS had to reduce its number of staff and other resources by
half. Then the most effective tasks would be allocated to the remaining 50% of
the staff. The cost-effectiveness of different interventions carried out by the
NHS likely differs by several orders of magnitude. Vaccination programs can
produce a year of healthy life22 for under £100, while the NHS funds
interventions which cost up to £30,000 to achieve the same benefit.23 So,
reducing the resources of the NHS by half could bring about a much smaller
reduction in its benefit than 50%.
Consider the two plausible premises:
1. The activities of most organisations differ in their effectiveness
22
23
Technically called a QALY, as explained in (Preito & Sacirstan, 2003)
(McCabe, Claxton, & A, 2008)
48
2. Most organisations make some attempt to prioritise their distribution of
resources to increase their impact
If one accepts (1) and (2), then reallocation of tasks will occur in most organisations.
The size of the effect depends on (i) the scale of the differences in effectiveness
between different activities and their distribution, and (ii) the degree to which tasks
can be reassigned.
This effect will tend to minimise the difference one makes by taking or not taking a
job. Even in the case when you’re not replaceable, it’s not the case that all of the value
you create in that position would be lost. Rather, the most important tasks you
would have performed will be done by someone else. Here’s an example:
Reallocation, no replacement
Chris and Mia are equally skilled heart surgeons at a hospital. Suppose Chris
didn’t become a surgeon and there was one fewer surgeon at this hospital.
Then, the most high priority operations he would have performed would be
given to Mia. So, perhaps Mia achieves a higher success rate or works harder.
Some of the patients would be sent to other hospitals. Chris’s absence won’t
mean that 50% of the benefit is lost.
Even if you are replaceable, reallocation could still take place. The most important
tasks you would have done might still be reallocated to someone besides your
replacements, compensating for any difference in skill, and reducing the effect of
your absence. For instance:
49
Reallocation, with replacement
Chris doesn’t become a surgeon and is replaced by someone less skilful.
Then, the more difficult operations will be assigned to Mia. This will
minimise the reduction in the success-rate.
Reallocation of tasks applies in most situations to some extent, has potentially large
effects acting in the same direction as replaceability. It must also be included in a full
analysis of the c-consequences of taking a career. For similar reasons to
replaceability, it deserves more attention.
5.3. Signalling Effects and Boycotts
Now let’s consider the three types of effects that potentially counteract the
importance of replaceability. Williams thought that George shouldn’t take the job at
the chemical weapons factory. He considered several reasons a utilitarian might give
in order to explain this intuition. These include the signalling effects of the choice –
“the effects on the public at large.”24
5.3.1. Personality Signalling
Signalling effects can take several forms. One is the effect of signalling a certain type
of personality. For instance, in explaining why it’s bad to lie, a consequentialist might
point out that just one lie can ruin one’s reputation for trustworthiness, which could
hamper one’s life in all kinds of ways. If people started lying prolifically, then all
24
(Williams & Smart, 1973) pp105
50
kinds of social institutions could break down. These negative consequences of lying
could explain why it’s normally good to be honest.
Personality Signalling
One’s actions indicate that one has a certain type of personality, which could
influence how one is treated by others.
In career choice, it might be that taking a career which involves directly doing good
signals that one is a moral person and not corruptible. Conversely, taking a career
that involves directly doing harm signals that one is selfish or uncaring.
Suppose you’re ethically motivated and pursuing a career that has c-consequences
on the order of saving hundreds of lives. Then it seems that the possible danger of
people treating you slightly better or worse is a small effect on this scale. The
exception would be if it prevents you from being successful with your career.
Perhaps being seen as a moral person makes you more likely to succeed. The size of
this effect on your career is only likely to be significant is one wants to radically
change fields. For instance, taking a charity job might signal that one is a moral
person to society at large. But, it’s not going to make you stand out within the 3 rd
sector itself!
Perhaps one’s friends and family will treat you differently if you signal that you are
immoral or moral. This could affect your happiness, which would also affect your
career success. On the other hand, it’s not clear that most jobs will cause friends and
family to treat you differently. Only a minority of careers are widely considered
highly morally commendable or condemnable. If a friend of yours enters a relatively
51
controversial career like investment banking, even if you think investment banks are
involved in morally dubious activities, you probably won’t end your friendship.
Overall, the effects are not only small relative to job-related consequences, but highly
situation dependent. They differ from job to job, and depend on the attitudes of one’s
friends, family and colleagues.
5.3.2. Precedent Signalling
More commonly raised is that one’s career choices could influence the actions of
others. One type of effect is the Precedent Effect:
Precedent Effect
By taking a certain career, one influences the career decisions of others
For instance, working in the 3rd sector could be good because it encourages other
people to work in the 3rd sector.
As Williams points out, this effect is highly situation dependent, and often small. The
extent to which one’s career choice is publicised, one’s level of status and the beliefs
of one’s peer group will be important determinants. Few young graduates seem to
exhibit much influence over the career decisions of their peers. This is because most
career options are well known. At best, if Ella enters investment banking she has a
small effect on the extent to which investment banking is regarded as a realistic and
socially acceptable option; but since the option to take banking jobs is well known
and promoted, the impact seems small. If, however, she takes a very unusual career
52
in a public style, then it seems more likely she will inspire others to do the same. For
instance, schools often promote the activities of famous alumni among their current
students, which could encourage these students to take similar paths. Precedent
effects could be large if one triggers a threshold, contributing to a boycott as explored
in §5.3.5.
5.3.3. Political Signalling
Career decisions can also signal political beliefs:
Political Signalling
By taking a certain career, one displays one’s political beliefs, which could
influence the actions of others
For instance, taking a job in banking (causing harm, for the sake of argument) in 2012
could have negative effects because it signals support for current economic system
and all its ills.
Political Signalling is, like Precedent Signalling, situation dependent and often weak.
5.3.4. The Replaceability of Signalling Effects
The actions that lead to signalling effects are often themselves replaceable. Suppose
taking a high profile job in banking has bad signalling effects. But if you don’t take
the job, someone else will. That person will create the bad signalling effects in
roughly the same way you would have done. They would display to all of their
friends that they support capitalism and so on. So, for jobs in which you would be
53
replaceable, there’s apparently little net change in the total amount of negative
signalling if you take that job.
This is a simplification, because these cases also involve a chain of replacements.25
Suppose you’re considering whether to take a certain 3rd sector job and you believe
that 3rd sector jobs have positive signalling effects. If you don’t take it, then someone
else will, so apparently you’re having no signalling effect. But if that person will only
take a job that directly does good (e.g. will only take 3rd sector jobs), then although
they don’t take your job, they’ll take another 3rd sector job. If this increases the total
pool of people in 3rd sector jobs, then you might still have a positive signalling effect.
It would depend on whether the final person in the chain ends up in a job with a
positive signalling effect, and how large this effect is.
Moreover, even if you would be replaceable, you could still add to the total pool of
applicants for that job. That has some signalling effect in itself. The fact that
investment banking jobs continue to have huge numbers of applicants per place even
after the financial crisis suggests that many people believe they are not unethical.
5.3.5. The Modification of Signalling Effects
All three signalling effects can be modified by how one acts in the other areas of one’s
life. Ella’s taking of a job in banking might normally be perceived as (i) selfish (ii) a
show of support for capitalism and (iii) setting a harmful precedent for her peers,
Signalling effects could in large part be included in the apparatus of the Sophisticated
Analysis §4
25
54
causing all three types of negative signalling effect. However, if the job is taken for
ethical reasons – reducing the harm done by banking26– then the signalling effects
change. Suppose Ella is generally known to be a moral person outside work. Then,
the Personality Signalling effect becomes much smaller, since her friends and family
still believe she is a moral person. The Political Signalling effect potentially changes
from negative to positive. Rather than displaying support for capitalism, taking the
job displays a recognition of its harms, and a desire to reduce them. If this is positive,
then the Precedent Effect also becomes positive, because it’s good to encourage
others to do the same.
Since few people enter banking with the explicit intention of making it less harmful
(rather than the aim of making a lot of money), the signalling effects are often
negative in practice. It’s easy to confuse this with the signalling effects being negative
in general. If a strongly ethically motivated person enters banking, however, the
signalling effects could be very different.
5.3.6. Organising Boycotts
One might respond that if these arguments are taken seriously in general, it would
stifle the chance of social change, leading to worse c-consequences than we took the
Naïve View. Here’s an argument to that effect:
26
Or making large philanthropic donations
55
Tish the Wheat Trader
1. Tish believes that wheat trading jobs on balance produce negative value, so a
world without them is better than a world with them.
2. However, she takes replaceability into account, and reasons that the perfect
replacement condition holds.
Perfect Replacement Condition: if she takes the job, someone else equally
good would take it, so the c-consequences of the decision are zero
3. So, Tish takes the wheat trading job, believing that it s ethically neutral.
4. Universalization Test: If everyone reasoned like Tish, then people will continue
to apply to these jobs, and wheat trading will continue to exist.
5. If everyone instead avoided jobs that directly produce harm, then wheat
trading would cease to exist
6. So, the world in which everyone reasons like Tish is worse than the world in
which everyone acts as if the Naïve View is true
7. So, one should in general not take replaceability into account
First note Perfect Replacement is an unlikely condition, and it’s especially unlikely
that everyone would believe it. Normally, R>0, so taking a harmful job still causes
some harm through the job-related consequences. Tish will also have a small but
negative Precedent Effect, since she adds to the total number of people applying to
the job. But let’s assume it holds in this case and everyone believes it.
56
We then apply a universalization test. Failing this test would imply it’s wrong to act
according to the principle according to some ethical systems, like rule
consequentialism. It’s also taken to entail that one shouldn’t campaign to raise
awareness of the idea, but notice that this doesn’t actually follow unless one expects
to persuade everyone to believe it (or makes a more complex argument).
Let’s assume everyone believes the condition and that universalizability matters.
Considered at an instant, agents would continue to apply to wheat trading jobs. But
in reality, agents can communicate. This means there is some chance of organising a
boycott of wheat trading. Tish should take into account that there’s some (perhaps
very small) chance that her career choice hampers the boycott through the Precedent
Effect. This is an additional negative effect of taking the career, which means it’s no
longer ethically neutral.
So, we’ve actually shown that Perfect Replacement should only be believed if
understood as:
Perfect Replacement is true, if everyone else’s actions are fixed.
If one takes into account the chance of organising a boycott, then it can’t be the case
that everyone truly believes Perfect Replacement. Note that we haven’t shown
anything about Imperfect Replacement, which is the normal case.
57
A similar type of example been explored by Shelly Kagan.27 For instance, consider his
example:
Polluting Factory
A factory emits a gas which is thinly scattered across the surrounding area so
that no person breaths in more than one of the molecules. One molecule has
no effect on one’s health. However, there are thousands of similar factories.
Inhaling thousands of molecules has a very negative impact on one’s health.
Each factory owner apparently makes no difference, since one molecule never
makes a difference. The end result is very destructive, far offsetting the value
produced by the factories.
We could now suppose Tish believes that a boycott is possible, but that her choice
has a negligible effect on its chances of success:
Vague Replacement Condition
If one extra person takes a wheat trading job, it won’t affect whether a boycott
of wheat trading happens or not.
This condition seems implausible in the case of career choice. In reality, Tish does
make some difference to the chances of a boycott, it’s just very small. Kagan points
out that if the difference is small enough, then it will make an imperceptible
difference to people’s happiness. It’s unclear that imperceptible differences in
happiness could matter. In this case, we could mount a second response. Perhaps
Tish’s action has a high probability of making no difference, but a small probability
of making a significant difference. It seems plausible that social movements involve
27
(Kagan, 2011)
58
tipping points28. To organise a boycott requires some people to start, which could
encourage yet more people to boycott it. Ex-ante, there’s a small probability that
Tish’s career decision triggers a boycott of wheat trading. This is why the Vague
Replacement condition is false.
5.4. Effects on the agent’s feelings and personality
5.5.1. Introducing the effects
Williams also considers the fact that George feels that he doing evil by working at the
chemical weapons factory. Similarly, Jim might feel revulsion at having to kill an
Indian. I call these Emotional Effects.
Emotional Effects
Career choices could lead to positive or negative emotions for the agent and
the people the agent interacts with.
Emotional effects are often raised as a reason to overlook replaceability. If there’s a
correlation between doing good directly and feeling good, then it’s a reason to
favour doing good directly. Also note that most people regularly interact with tens
or hundreds of other people outside of their job. If their job makes them miserable,
then it could negatively affect these people too.
28
For a detailed model, see (Granovetter, 1978)
59
Emotional effects are linked to two other kinds of effects on the agent. First, jobs that
involve doing good directly could be easier to stick with, so have a lower risk of
burn-out29:
Burn-out Risk
The chance that someone gives up on a career because they find it too
demanding.
If being involved in harmful activities makes you unhappy, then you might have a
high risk of burn-out, reducing the expected-value of the choice.
Second, pursuing jobs that directly cause harm involves a risk of Corruption:
Corruption Risk
The risk of corruption is the risk that the agent’s moral beliefs or ability to act
on those beliefs are negatively changed by their working environment.
The people one works with have a subtle influence on one’s moral beliefs over time.
Moreover, the types of activities one is engaged in could alter one’s dispositions to
act in the future. For instance, some results in psychology suggest that thinking
about money increases one’s disposition to be materialistic.30
5.5.2. Situation Dependence
Before going into Emotional Effects and Burn-out risk in more detail, note that all
three effects are highly situation dependent. While one person might find wheat
trading repulsive, another might not, even if they also believe it’s harmful. The
29
30
Burn-out and Corruption are introduced and explored in (Crouch, Unpublished)
(K. D. Vohs, 2006)
60
danger of moral corruption also varies greatly between people and between jobs.
Some people will even inspire their colleagues to act more ethically.
Furthermore, one can often purposely alter the situation in order to offset these
affects. For instance, if one is worried about being corrupted or burning out, one
could (i) associate with a group of like-minded people (ii) make a public declaration
of your intent to act ethically. The negative emotional effects of a career could be
counteracted by focusing on the good one can do in other aspects of one’s life.
5.5.3. Emotional Effects
If one becomes significantly less happy, and that impacts the happiness of the
hundred people you most regularly interact with, that might be good reason to avoid
an ethically neutral job. But if hundreds of lives turn on the decision, then that
outweighs the Emotional Effects. After all, the value lost to 100 people through being
less happy is small compared to the value lost if 100 people die. Williams argues for
the same point. Even if George hates his work at the chemical weapons factory, it’s a
minor consideration compared to the suffering that could result from the weapons
developed by the zealous researcher.
Emotional effects might lead to other effects that are significant. For instance,
negative emotional effects could increase the risk of burn-out or corruption. They
could also hamper one’s effectiveness in a job. This could be very significant, and is a
good reason not to take a job that one hates even if seems very high impact.
61
5.5.4. Burn-out
The burn-out risk of a career path will generally lower its expected value. Whether
this should change your career decision depends on what job you would go into if
you burn-out, and how much good you do before you burn-out. Consider someone
choosing between professional philanthropy and 3rd sector work. The risk that they
burn-out might be higher in professional philanthropy (depending on the person,
and note there’s a risk of burning out in the 3rd sector too!). But, if they believe the
annual value produced by professional philanthropy is much higher than through 3rd
sector work, it might be worth attempting. Depending on the nature of the highearning job, even if they burn-out, they might still be able to enter a similar 3rd sector
job.
Burn-out risk also shows that being overly zealous in the pursuit of maximising cconsequences is unlikely to be a good strategy.
5.5. Supply-Demand Effects
5.5.1. Introducing the effects
One’s career choices have an effect on the supply and demand for certain jobs. Being
willing to take a certain type of job increases the supply of labour for that type of job.
This has two effects: (i) it decreases equilibrium wages, decreasing industry costs,
and (ii) the industry will hire more people to do that kind of job.
62
For markets assumed to be in equilibrium, one can use neoclassical economic models
to estimate the size of these effects, provided one knows the elasticities of labour
demand and supply for the relevant industry. The elasticities are difficult to estimate
empirically and a subject of intense debate in economics31. Nevertheless, one can
make rough estimates.
If the elasticity of labour demand is -1 (a reasonable central estimate32), then since the
elasticity of supply ranges from 0 to infinite, increasing the labour supply 1% causes
an increase in the quantity of labour supplied from 0% to 1% at the new
equilibrium.33 This means that adding yourself to the supply causes, on average,
between zero and one unit of job-creation in the industry. Most likely, the true figure
lies somewhere in the middle.34 So, the Iteration Effect chain ends somewhere
between job-creation and no job-creation.
It also causes a -1% to 0% change in the wage rate. This means that adding oneself to
the supply on average means that wages reduce so that the industry’s costs decrease
by zero to one (average) person’s salary.
If the elasticity of labour demand is -0.5, which would be more typical of jobs with
high qualifications, then a 1% increase in supply, causes a 0-1% increase in quantity
supplied (most likely 0.5-0.66%), and a -0.5%-0% change in the wage rate.
This meta-study shows that elasticity of supply estimates range from below zero to over 2:
(Evers & R. de Mooji, 2005)
32 This well-cited book includes a study of manufacturing jobs, finding values of -0.9 to -1.4
(Hamermesh, 1996).
33 I assume both elasticities are linear since I m considering small changes.
34 It s .33% to .5% if the elasticity of labour supply is from .5 to , which is in line with the
best estimate in this meta-study: (Evers & R. de Mooji, 2005)
31
63
It’s difficult to estimate the significance of this effect compared to job-related
consequences. It depends on the value produced per unit of profit, compared to the
value produced by someone in a job.
5.5.2. Non-equilibrium, Imperfect Markets
The above only applies is the labour market is in equilibrium and describable by
neoclassical economics. In reality, labour markets are frequently out of equilibrium
and not perfectly competitive. Real markets involve persistent unemployment,
suggesting the average job is over supplied. This would mean one’s true impact on
wages is less than what I’ve just estimated.
Some industries support wages in excess of the rates required for markets to
equilibrate. The financial services sector currently has large excess wages of ~50%35
suggesting that adding oneself to the supply has almost no effect on wages or jobcreation. This supports the intuition that hugely competitive application processes
mean that a single applicant has effectively no impact on wages.
5.6. Conclusion
As shown, none of these effects provides a general reason to neglect replaceability.
They can be highly relevant if one believes that most careers are roughly neutral in
their c-consequences. This belief could explain why we typically put a lot of weight
Estimated by comparing wages between jobs requiring similar skills (Philippon & Reschef,
2009)
35
64
on them in careers advice. For someone ethically motivated however, the difference
in the job-related c-consequences between different choices could easily be on the
order of saving hundreds of lives. Then, except insofar as they indirectly impact the
job-related c-consequences, these other effects are outweighed.
65
6. Non-Consequentialist Considerations
6.1. Introduction
Although, as shown in §2, c-consequences are morally relevant, according to nonconsequentialist views they are not the only factor that’s morally relevant. Perhaps
it’s just wrong to take certain careers, because they violate rules we should all
respect. Or perhaps taking harmful careers compromises our integrity; while doing
good directly is virtuous. Indeed, Williams uses the fact that George is replaceable
precisely to show that not only c-consequences are morally relevant.
Consequentialists reject the relevance of these factors. So, for consequentialists, I’ve
already shown that replaceability is a crucial consideration. Nevertheless, I will show
that despite Williams’ example, the c-consequences of career decisions typically
dominate which is ethically preferable even for non-consequentialists. I will explore
three non-consequentialist considerations: side constraints, virtue and integrity. I
show that neither outweighs c-consequences in general.
Before I begin, note that since I’m only concerned with the ethical preferability of
different options, demandingness is not relevant to my argument. If the most
preferable career is highly demanding, it might be permissible not to take it, but it
will remain the most preferable option.
66
6.2. Side Constraints
6.2.1. Careers in the Mafia
Deontological non-consequentialist theories involve the addition of Side Constraints:
Side Constraints
Principles that prohibit certain actions, no matter the c-consequences
Common Side Constraints are principles like ‘never use people as a means to an end’
or ‘never torture.’ If one adopts Side Constraints, then they outweigh c-consequences
whenever they apply.
One can argue that Side Constraints are relevant by applying replaceability to an
illegal career:
Lorenz the Mafia Boss
If Lorenz doesn’t work for the Mafia, someone else will, since in his town
unemployment is high and lots of young men want the money. However,
since he’s ethically motivated, he will aim reduce the harm that would have
been done otherwise by reducing the number of shootings.
Supposing this is the career with the best c-consequences open to him, should Lorenz
take the career? Most people find this career impermissible, despite the net positive
c-consequences. Presumably this is because entering the Mafia violates Side
Constraints.
In fact, there are good consequentialist reasons to think such a situation is extremely
unlikely. Although in §5 I argued that the other c-consequences of career decisions
67
are typically outweighed by the job-related c-consequences, this doesn’t seem to be
the case for illegal careers. Let’s compare a typical ‘unethical’ career, banking, with
this example.
1. Since Lorenz is ethically motivated, it s difficult to imagine he could really go
through with the career. He would burn-out. There are, however, ethically
motivated bankers, suggesting the same is not true of banking.
2. Careers in the Mafia are rare and illegal, so the signalling effects of an extra
person attempting to join the Mafia even if Lorenz doesn t increase the
number of people in the Mafia) are strong. The same is not true of banking,
which employs thousands of young graduates each year and is not illegal.
3. Working for the Mafia carries significant risks of violent death or
imprisonment, which would be extremely stressful for Lorenz and all his
friends and family, so there are large negative Emotional Effects.
4. Criminal organisations, which offer job positions, are often labour constrained
due to the risks associated with these careers. So, criminal careers are often not
replaceable.
So, it’s not replaceability that caused the problem; rather, it was neglect of the other
consequences. Suppose the career in the Mafia really is the career with the best
consequences for Lorenz. A consequentialist must bite the bullet and concede that he
should take the career. If one still finds it impermissible to take the career, then nonconsequentialist factors must be relevant.
68
The career in the Mafia is apparently analogous to a Transplant Case36. This involves
a doctor killing a healthy patient in order to use their organs to save the lives of five
others. This clearly seems impermissible. A non-consequentialist explanation is that
it violates the rights and autonomy of the health man. Similarly, Lorenz shoots
different people from his replacement, in order to reduce the total number of
shootings.
6.2.2. Side-Constraints in Typical Career Decisions
If one adopts Side Constraints, how are c-consequences ethically relevant? A
plausible position is that so long as Side Constraints are obeyed, actions are ranked
in order of ethical preferability by their c-consequences. Suppose there are three
actions open: A1, A2 and A3. One adopts Side Constraints, which prohibit A1. The
other two actions are permissible. But suppose the c-consequences of A3 are much
better than A2. Then, A3 is ethically preferable to A2. A3 might be a moral obligation
or superogatory.
This model gives the right answer to Paul and the Paramedics. Both performing first
aid and letting the paramedics work are (presumably) permissible, but letting the
paramedics work is ethically preferable.
How much impact might Side Constraints have on career choice? Let’s define37:
36
37
As introduced in (Thomson J. J., 1985)
After (Crouch, Unpublished)
69
Morally Innocuous Career
A career which lacks a strong non-consequentialist reason against taking it.
In particular, taking a Morally Innocuous Career doesn’t involve violating a Side
Constraint. It seems plausible that most careers are morally innocuous. Any nonharmful career is unlikely to violate a Side Constraint. Most careers are not seen as
harmful, so most career are morally innocuous. For these careers, c-consequences
determine which is ethically preferable.
Side Constraints have the best chance of being relevant when considering unethical
careers. But even considering careers that are often claimed to be unethical, it’s not
clear that taking the career violates Side Constraints. One should distinguish the act
of taking a career from the morality of the typical people in that career. For instance,
it’s plausible that banking is considered unethical because in the recent past many
bankers have been unethical. This doesn’t mean that entering banking is unethical.
Actions that violate Side Constraints are widely regarded as wrong. It’s not widely
considered wrong to take most unethical careers, like being a trader at a bank,
working for big oil or being a corporate lawyer. Rather their status as unethical is
controversial. This suggests that even taking typical unethical careers does not
violate Side Constraints. At the least, taking these careers is certainly not considered
as bad as killing or torturing someone. It’s less clear that taking them, however, is not
like violating a minor Side Constraint like not lying.
70
It might be that most people are wrong about the moral status about these careers.
The mechanisms by which they cause harm are often complex. Since they don’t
involve directly harming, people are unwilling to declare them as morally
reprehensible as burglary. Nevertheless, if they were sure about the mechanisms by
which harm was caused, they would find them equally bad. So, although there’s
some reason to think that even taking typical unethical careers doesn’t violate Side
Constraints, it’s unclear.
We don’t need to be clear, however, because even if we consider a career such that
taking it does violate a Side Constraint, there are still three situations in which taking
the career is still permissible in light of the c-consequences:
1. Emergency Situations
2. Pareto Improvements
3. Trolley Cases
I provide a preliminary discussion of each, arguing that Side Constraints are often
outweighed by the c-consequences of career decisions even when they are indeed
violated.
6.2.3. Emergency Situations
Threshold theories permit Side Constraints to be overwhelmed when the cconsequences are large enough. Many deontologists admit the existence of
thresholds due to Ticking Bomb cases. In these, one is asked to choose between
saving a large number of people and violating a Side Constraint, such as torturing
71
someone. The number of people can be made arbitrarily large, making it implausible
to hold onto the Side Constraint. The response of deontologists is to postulate
thresholds at which point c-consequences overwhelm Side Constraints.
If replaceability means that the c-consequences of taking a career are very positive,
then it could be permissible according to these theories to enter the career even if it
would violate a Side Constraint. For instance:
George and the Bioweapons Lab
George is offered a second job at a bioweapons lab. He suspects the lab is
working on an extremely dangerous and risky virus. He believes that by
working at the lab he can delay the progress of the research by working less
efficiently than the typical researcher. Even a small delay to the program has
high expected c-consequences.
Suppose George thinks that contributing to this research violates Side Constraints,
such as profiting from the suffering of others. If the expected c-consequences were
large enough, it might overwhelm the Side Constraints. Careers that involve
espionage or sabotage could also be of this kind. The German military leaders who
died attempting to assassinate Hitler during WWII are often considered heroes. Spies
who lie and kill for the country often celebrated too, at least in fiction. It’s plausible
that in entering politics, one might expect to have to eventually violate side
constraints. Nevertheless, this could easily be outweighed by the potential to benefit
millions of citizens.
72
6.2.4. Pareto Improvements
One reason it seems to be impermissible to kill the healthy patient in the Transplant
Case is that it violates that patient’s rights. This is because the surgeon changes who is
harmed. This is not the case with Jim and the Indians. If Jim asks the Indians what he
should do, the one who he is going to kill is indifferent, because he will be killed
anyway. The other 19, however, will be saved, so prefer Jim to kill the single Indian.
So, some of the Indians benefit and none is made worse-off by Jim’s action38, thus the
action is a welfare Pareto improvement.
Since Pareto improvements don’t involve acting against anyone preferences, it’s
widely accepted that they are permissible, even if they might violate a Side
Constraint (such as killing). Williams himself accepts that it’s preferable for Jim to
kill the single Indian.
It’s not plausible, however, that entering many harmful careers brings about a Pareto
improvement. One will act differently from one’s replacement, which means that
ultimately different people will be harmed: the banker will place slightly different
deals and George will develop different weapons. Even if it does, it will be extremely
difficult to know that it does. Our actions in careers have very complex effects. If
anyone is made worse off by an action to any degree, then it’s not a Pareto
improvement.
More plausibly, however, taking a harmful career in order to have positive cconsequences could often be an ex-ante Pareto improvement. This means that no-one
38
Ignoring Jim himself!
73
faces a negative expected-benefit before the action, even if it turns out to not be a
Pareto improvement ex-post. For instance, suppose Jim is told that if he doesn’t kill a
single Indian, Pedro will kill 10 of the 20 at random. Ex-ante, each Indian prefers Jim
to kill the single Indian, because that increases their chance of survival from 1/2 to
19/20. Ex-post, however, it could be true that the Indian Jim kills would not have
been killed by Pedro, so Jim’s action made that Indian worse off. Ex-ante Pareto
improvements still have the attractive feature that no-one’s desires prior to the action
need to be over-ridden.
Since the harms caused by many careers are so indirect, it’s often impossible to know
who will be harmed. If someone is planning to do significantly less harm than their
replacement, however, then it’s plausible that no-one faces a negative expectedbenefit. This is particularly likely if we restrict our attention to the victims of
unethical careers. For instance, investment banking is considered bad because of the
suffering inflicted on the poor by financial crises. The impact of any single banker on
the details of a financial crisis is unknown. So, if a banker expects to lower the risk of
financial crisis, then each poor person in the society might face an expected-benefit.
In fact, some poor people will be made worse off by the change in timing of the
crisis, but this is not known in advance.
One problem with using ex-ante Pareto improvements is that although taking the
career might be one, it might be necessary to perform actions that aren’t ex-ante
Pareto improvements during the career. For instance, it might be known by an oil
company is going to harm several villages in the developing world but it’s not
known which. Graham will harm fewer villages than his replacement if he gets the
74
job, so all of the villagers prefer Graham to take the job. Nevertheless, once Graham
is actually in the job, he has to pick which villages will be harmed. The action of
picking is not an ex-ante Pareto improvement.
My intuitions about what Graham should do are unclear. One answer is that he
should resign if he finds himself in this situation. Alternatively, it could be
reasonable to treat the career as a single action.
6.2.5. Trolley Cases
In the Trolley Case39 a run-away trolley is hurtling towards five people on a track. You
have the option to divert the trolley onto another line, so that it only kills one person.
Unlike the Transplant Case, many people have the intuition that it’s permissible to
divert the trolley, killing the one person.
The Trolley Case is not a Pareto improvement, and many different arguments have
been put forward as to why it’s permissible to divert the trolley. Thomson40 has
argued that it’s because by diverting the trolley, one is diverting a pre-existing
threatening force by acting on the force. In the Transplant Case, however, the
surgeon creates a new threat in killing the patient. The Trolley Case is like a pilot
diverting a crashing plane into a lowly populated area. Different people will be
harmed, but it seems clearly better to minimise the destruction, even if the ratio of
harm to benefit is significantly smaller than five to one.
39
40
First raised in (Foot, 1967)
(Thomson, 1986)
75
Entering a harmful career with the intention of making it less harmful often seems
analogous to the Trolley Case. Careers roles that produce negative value are preexisting threats. This is because if you don’t act, someone else will take the career and
cause the harm, just as the trolley would hurtle into the five people. It’s ethically
preferable for you to take the position and divert the harm that would be done.
Similarly to manipulating the trolley, one acts on the threat to yield the benefit. As a
banker, one makes different deals. As an oil engineer, one makes different plans. One
doesn’t directly harm, as with killing the healthy patient or Lorenz shooting different
people.
A source of dis-analogy is that these career choices seem to be dilemmas of acquiescence
rather than of necessity.41 Diverting the trolley is a dilemma of necessity, because the
trolley is not an agent. Rather, it’s a mindless harmful force. The danger that one’s
replacements will be more harmful than oneself because they are less ethically
minded is a dilemma of acquiescence. It involves an agent’s decision to act
unethically. Woodard claims that this provides additional reason not the take the
harmful career. It’s unclear whether this outweighs the other ways in which the
Trolley Case is analogous. Moreover, it’s not true of all cases. For instance, if one’s
replacements would be more harmful because they are less well informed, then it
would no longer clearly be a dilemma of acquiescence.
Switching the path of the trolley is also justified with an application of the widely
accepted Doctrine of Double Effect (DDE). DDE states that it’s permissible to harm if
(i) it’s in the pursuit of a much greater good and (ii) one doesn’t intend to cause the
41
Explored in (Woodard, 2009)
76
harm. One doesn’t intend to kill the single person on the track. Rather, their death is
an unintended side-effect of one’s efforts (diverting the trolley) to save the five
people. This is not true of the Transplant Case, which seems to involve an intention
to kill the healthy person.
Many legal, but unethical careers, however, don’t involve intending to do harm. A
banker selling complex securities doesn’t intend to harm anyone (unlike a fraudulent
banker). She intends to earn a profit, and would earn the profit in a less harmful way
if it were possible. It’s an unintended side-effect that these securities contribute to
financial instability. The Mafia, however, intends to kill people in order to intimidate
others. If the c-consequences are great enough, then DDE could justify entering an
unethical career provided the activities don’t involve intending to do harm.
Note that, under DDE, it’s permissible to create a threatening force as long as one
doesn’t intend to do harm. For instance, tactically bombing a munitions factory to
prevent war might be permissible, even though an unintended side-effect is to kill
civilians. This is particularly relevant to professional philanthropy, because pursuing
harmful careers can enable you to save thousands of lives through your donations.
It’s unclear whether the impact of donations can be included in the job-related cconsequences, making R<<0, and thus similar to a Trolley Case, or whether it might
be that R>0 so more like a Tactical Bombing case.
77
6.2.6. Conclusion
Side Constraints aren’t relevant to most career decisions, so c-consequences
dominate. Even taking some unethical careers probably doesn’t violate Side
Constraints. Moreover, even if they do, it could still be permissible to take the career
if it’s an emergency situation, ex-ante Pareto improvement or analogous to a Trolley
Case. Answering exactly when it’s permissible requires a much more detailed
application of the latest ethics of permissibility.42
6.3. Virtue
Virtue Ethics places moral relevance in the character traits of agents, which is a
natural but completely different way to think about ethics from consequentialist or
deontological theories. I’m not able to do justice to Virtue Ethics, but I discuss it
because it’s often thought that careers doing good directly enable one to express
more virtuous traits. Sarah should persist in becoming a surgeon because this
enables her to express a character that’s compassionate, courageous, honest and so
on. The opposite seems to be the case for harmful careers. This suggests that
replaceability is not relevant in Virtue Ethics.
C-consequences must still be important in Virtue Ethics, however, due the example
of Paul and the Paramedics (§2.2). Any reasonable ethical system must have
something to say about why it’s bad for Paul to paralyse his mother. The importance
of c-consequences is embodied in virtue of beneficence – the virtue of helping others
and preventing harms. By taking the job at the chemical weapons factory, George can
42
As developed, for instance, in (Kamm, 2007)
78
(by supposition) prevent harm, so he’s acting beneficently. All else equal, it’s better
to be more beneficent rather than less, so careers with better c-consequences are to be
preferred.
Is all else equal? It seems the majority of morally innocuous careers provide equal
opportunities to express one’s virtuous character. The difficult case involves harmful
careers. Even then, it’s not clear taking the job compromises George’s ability to
express a virtuous character. Rather, so long as he’s not corrupted43, he would show
considerable courage and determination by placing himself in an environment he
finds repugnant in order to help others.
Further, virtuous character traits are not blindly followed rules. Rather, one
embodies beneficence or honesty with a degree of practical wisdom. Consider44:
An honest person cannot be identified simply as one who, for example, always tells
the truth…for one can have the virtue of honesty without being tactless or indiscreet.
Ordinarily taking the harmful job is perhaps not virtuous, especially if it’s for
personal gain. However, if lives are at stake, George need not blindly follow these
rules in order to be a virtuous person.
A strength of Virtue Ethics is that it encourages a holistic assessment of someone’s
morality. If George embodies virtuous character traits throughout the rest of his life,
we might judge that he remains a virtuous person even if his career involves some
43
44
A more important danger in Virtue Ethics
SEP, (Hursthouse, 2012)
79
activities that would normally not be considered virtuous. We know, for instance,
that George is morally opposed to chemical weapons and is ethically motivated. In
this context, it seems highly virtuous for George to take the job and seek to reduce
the suffering caused by chemical weapons.
A wide variety of careers are potentially virtuous. This leaves c-consequences and
the virtue of beneficence as the primary determinant of differences between choices.
6.4. Integrity
It’s often considered morally wrong to take careers doing harm because they violate
one’s integrity. Williams argues that this is why George shouldn’t take the job at the
chemical weapons factory, and moreover, that this fact can’t be explained merely in
terms of c-consequences. Integrity might also be proposed as reason to take careers
that directly do good, even if they don’t make a difference.
One might think that integrity just consists of a particularly strong form of Emotional
Effect on the agent (§5.5.3.). Williams argues that Emotional Effects are unlikely to be
strong enough to show that George shouldn’t take the job. After all, George is just
one man, and the work at the chemical weapons factory is likely to (by supposition)
to contribute to the violent deaths of many more people. A consequentialist would
respond that in this case, George should take the job. For Williams, there is a morally
relevant consideration over and above the c-consequences.
80
For Williams, integrity consists of the intrinsic value of staying true to one’s life
projects. George is morally opposed to chemical weapons, and so shouldn’t involve
himself in their manufacture. But it’s plausible that not being involved in chemical
weapons research is not among the life projects of many other people. In that case,
integrity’s not a consideration and they should take the job if in a similar situation.
The relevance of integrity varies from person to person and from job to job. Cconsequences remain highly ethically significant because they determine what
should be done whenever integrity is not relevant.
Integrity can, like Side Constraints, be outweighed. Williams thinks that Pedro is
making an attack on Jim’s integrity in forcing him to kill an Indian – it’s among Jim’s
life projects not to kill innocents. But Williams thinks it’s right for Jim to kill the
single Indian. It’s not worth Jim preserving his integrity at the expense of the lives of
19 Indians. Harmful careers could easily involve harming people on this scale. So, if
one can enter one of these careers with an expectation of bringing about less harm
than would have happened otherwise, it’s plausible that integrity is outweighed. In
fact, it’s quite plausible George is a case of this sort too. It seems that George should
take the career despite his integrity45.
Integrity based objections to replaceability often turn on a confusion. It’s often
unclear exactly what someone’s life projects are. We’re told that George is morally
opposed to chemical weapons, so his life projects include not contributing to research
into chemical weapons. But, perhaps George’s life project is actually preventing the
use of chemical weapons. The first implies that he shouldn’t take the job. The second
45
Overlooking that it might not be a Pareto improvement like Jim s action
81
implies that he should take the job, because by taking the job he can hamper the
development of chemical weapons, reducing the scale on which they are likely to be
used.
The second project seems to be the better project. Williams distinguishes lower-order
projects, like preventing the use of chemical weapons, from higher-order projects,
like the utilitarian project of searching for the greatest happiness of the largest
number of people. It’s plausible that whatever George’s higher order projects are,
they are better served by the project of preventing the use of chemical weapons on
people than the project of never researching chemical weapons. After all, what’s bad
about chemical weapons isn’t that we know about them, it’s that they might be used
to harm people.
Raising integrity could even be question-begging in this context. Our career is one of
our life projects. I’m making an argument about which career is ethically preferable.
Thus, I’m making an argument about which life projects are best to have. So,
responding to my argument by saying that it conflicts with our life projects begs the
question.
Williams responds that a moral theory which requires us to change our most deeply
held life projects is too demanding. I, however, have set aside considerations of
demandingness,46 so integrity isn’t relevant.
But see (Ashford, 2000) for a response
46
82
6.5. A Real Example
These examples might be considered unintuitive, but consider a real life case. Oskar
Schindler47 took a job producing weapons for the Nazi Government during World
War 2. This sounds like a career that would certainly violate Side Constraints and
Schindler’s integrity. But Schindler is widely acclaimed as a hero, as celebrated in the
book Schindler’s Ark and the film Schindler’s List. His biographer called him, “one
of the most remarkable Righteous Gentiles in the Holocaust.”48 This is because he
purposely made the factory less efficient, so that it would produce fewer arms than it
would have produced otherwise. He also used his position and money to save the
lives of around 1000 Jews. Schindler could have fled the country, but he stayed in his
position, helping the victims, earning our moral praise.
6.6. Conclusion
Side Constraints and Integrity turn out to normally not be relevant to career choice.
Moreover, when Side Constraints are relevant, they are often outweighed by cconsequences, so it’s permissible to take the career with the best c-consequences
anyway.
Virtue Ethics doesn’t judge individual actions as right or wrong. Rather, certain
careers enable one to be far more beneficent than others. Lacking a reason to believe
these careers are much less virtuous in other ways, it’s preferable to take them.
47
48
This example is borrowed from (Crouch, Unpublished)
(Crowe, 2007) pp.624
83
Thus, in the majority of ethically motivated career decisions, even if these views are
relevant, it’s typically preferable to pick the option with the best job-related cconsequences.
84
7. Analogous Arguments
7.1. Introduction
A final type of objection to taking account of replaceability is that it’s analogous to
supposedly bad arguments like, ‘if I don’t buy the meat, someone else will,’ and ‘if I
don’t invest in the arms company, someone else will.’ In this section, I explore the
analogies and disanalogies between the cases. Rather than give us reason to ignore
replaceability, these examples deepen our understanding of it.
7.2. Replaceability in Vegetarianism
7.2.1. A Bad Argument
Consider a moral position in which eating meat is wrong due to the animal suffering
it leads to. Consider:
Supermarket Meat
Bob purchases some beef at the supermarket, which is about to sell out. He
argues that if he doesn’t buy the meat, someone else will, so it won’t affect the
welfare of the animal in question either way.
This is a bad argument because it neglects Bob’s supply-demand effect. In reality,
Bob causes a small expected increase in beef prices, causing a small increase in
quantity of beef supplied. Using realistic figures for fed-beef49, buying an extra 1 unit
of beef, causes an extra 0.8 units to be supplied to the market. So, there’s a grain of
truth in Bob’s argument. He doesn’t expect to cause all of the suffering associated
49
Taken from: (Langemeier & Thompson, 1967)
85
with 1 unit of beef. Rather, by raising the prices of beef, he on average causes
someone else to eat slightly less. So, he only causes the suffering associated with 0.8
units.
Note that similar arguments are made in the context of burning fossil fuels; for
instance, ‘if I don’t buy this plane ticket, someone else will.’ These arguments fail for
the same reason.
Note also that the supply-demand effect is different in career choice, because the job
one causes to be created will generally be occupied by a different person.
7.2.2. A Good Argument
Pepperoni Pizza at a Party
Bob is, unknown to his friend, vegetarian. Upon arriving at the friend’s party,
he discovers his friend has bought a large quantity of pepperoni pizza. He
reasons that if he doesn’t eat the pepperoni, someone else will. Either way, it
won’t contribute to animal suffering – there’s more than enough food for
everyone to fill up. He makes it clear that he would prefer vegetarian pizza in
the future.
Since this meat has already been bought, and in the future Bob’s friend won’t buy
more meat on his behalf, Bob doesn’t have a supply-demand effect. So in this case,
it’s true that he doesn’t directly contribute to animal suffering by eating the meat.
86
Many people have the intuition that he still shouldn’t eat the meat. This could be
explained by signalling effects. By being public about his vegetarianism, he could
encourage others to become vegetarian. As with the career choice signalling effects,
these will depend on the details of the situation and Bob’s friends. It might be that by
being a reasonable vegetarian who doesn’t want to let food go to waste, he’s more
persuasive.
Eating meat this time might make it harder for him to resist temptation at other
times. Forming the habit of never eating meat, might be the best way for Bob to be a
vegetarian. This is analogous to the Corruption Effect in career choice. Bob will need
to assess the size of these effects in the light of his situation.
7.2.3. Eating Meat Not a Good Analogy
These two examples have no analogue with the job-related c-consequences. Buying
meat does not produce a stream of value in the same way as occupying a job does.
The job-related c-consequences are often the most important factor in career choice,
so buying meat is also a bad analogy.
7.3. Ethical Investing
7.3.1. Introduction
Should universities invest in arms companies? Oxford’s recent investment of
£630,000 in Northrop Grumman, a company that profits from cluster bombs, was
87
considered headline-worthy50. In 2010, Oxford founded the Socially Responsible
Investing Review Committee, after pressure from the SRI Campaign. The campaign
states, “by modifying…its investments in line with its values, an institution can
recognise its moral responsibility, and have a practical positive impact in the
world.”51 It appears that investing in arms companies is considered unethical due to
its negative impact. But if Oxford doesn’t buy the shares, someone else will, so prima
facie Oxford makes no impact at all – or else there is something wrong with
replaceability.
Ethical investing is a good analogy with career choice, so it’s worth exploring in
some depth. Rather than reject replaceability, I show that we should rethink our
views of ethical investing. This also illustrates that the ideas in this thesis have wider
application.
Equities (stocks and shares) are fractional ownerships of businesses and are traded in
the stock market. Ownership consists most importantly of voting rights to appoint
directors, who make key business decisions. Equities are issued by businesses as a
way to raise capital.
Socially responsible investing is, most often, the practice of not buying the equities of
businesses that are involved in unethical activities. This is called negative screening.
The definition of ‘unethical activity’ varies, but generally involves activities that are
perceived to lead to significant harm e.g. arms manufacture; gambling and tobacco
50
51
As reported in The Independent (Taylor & Porter, 2011)
As taken from the archived SRI campaign website: (SRICampaign)
88
companies. Ethical investing can also involve positive screening (investing in
companies perceived to have positive social return) and shareholder activism
(attempting to use voting rights to positively shape company behaviour). The SRIR
Committee is open to activism, but so far the only action it has recommended is that
Oxford sells its investments in arms companies.52
7.3.2. Supply-Demand Effects
One effect of being willing to buy the equities of arms companies is to increase
demand for these equities. The market for equities, however, is not like the labour
market. According to the Efficient Market Hypothesis (EMH), equity prices are at in
equilibrium about a fair value. So, ignoring transaction costs, equity owners are
indifferent to holding the equity. This means that by purchasing the equity, one has
no effect on its price.
The EMH is hotly debated53. An alternative model is that each equity holder has a
different price at which they are willing to sell. If one wants to purchase an equity,
one must bid up the price until enough people are willing to sell. So, purchasing an
equity raises the price. In reality, small marginal buyers have approximately no effect
on prices. They are known as price-takers. As the size of one’s purchase grows, one
has more and more impact on prices.
52
53
(SRIR-Committee, 2010)
For a summary of critical views, see (Malkiel, 2003)
89
Oxford was approximately a price-taker in the context of its purchase of £630,000 of
Northrop Grumman equity, which amounted to less than 0.01%54 of the total
quantity available.
Supposing Oxford could increase the market price of Northrop equity, it’s not clear
this effect would last. Only 12% of the U.S. equity market is ethically invested55, so
the remaining 88% would buy additional units of Northrop equity, profiting from
the difference between the new price and fundamental value. A sustainable price
decrease could only happen if so many people boycott the stock that it exhausts the
capacity of non-ethically motivated arbitrageurs.
Let’s suppose Oxford did increase the price, what effect would that have? The main
mechanism by which it could lead to more harm is that higher equity prices are
taken as an indication that if the company were to issue more equity, it would fetch
higher prices. This makes the company more credit-worthy, and so better able to
grow its business.
Even then, if Northrop is made more successful at the expense of another cluster
bomb company (a compensation effect), it’s not clear that more cluster bombs will be
created or used. However, we expect that on average the cluster bomb industry is
made a little more credit-worthy, which could help it to grow. So, there is potentially
a small increase in harm.

7.3.3. The Costs of Negative Screening
Prima facie, negative screening reduces Oxford’s investment opportunity set,
reducing its scope for investment performance. Whether negative screening does in
fact reduce performance is a subject of intense debate.56 If it does, then since Oxford
uses money with the ethical aim of educating students and producing research, it has
a negative effect. This is analogous to professional philanthropists refraining from
taking high earning but unethical jobs.
7.3.4. Boycott vs. Control
If a very large number of people refused to buy Northrop stock, it would force the
price down, making the company less credit-worthy. If a significant number of
ethically minded people bought the stock, however, they might be able to use their
voting rights to positively influence investor behaviour. The analogy to owning the
equity and engaging in shareholder activism is taking the job and seeking to make it
less harmful.
For someone seeking to have a ‘practical positive impact’57, the question is whether
it’s easier to have impact through control or through seriously hampering its
activities through a boycott. This will vary from situation to situation. I’d suggest the
control option is often easier. One achieves some influence immediately and a block
of ethical investors can elect a director with only 20% of equity. The coordination
required for such actions is more complex than boycotting the stock, but still simple.
Oxford could publish lists of the companies it invests in, requesting help from other
56
57
For instance, this study argues that it has no effect: (S. & Walkshausl, 2011)
(SRICampaign)
91
ethically minded investors. In a market where only 12% is ethically invested58, it will
be difficult to hamper a company to any degree through boycott. In most cases,
negative screening means passing up the opportunities to change unethical
companies, and instead buying companies whose managements are already socially
responsible.
7.3.5. Signalling Effects
Signalling effects seem to be the most significant negatives. In particular, it
demonstrates Oxford is not boycotting the stock, making a boycott less likely.
However, in the light of the previous subsection, it might be better for Oxford to seek
to influence harmful companies anyway. Oxford could also declare that it would
boycott the stock if a significant proportion of the market joined in.
Buying the stock could also have a Political Signalling Effect – it shows that Oxford
supports arms companies. As with all signalling effects, its potency depends on how
well publicised it is and on how influential Oxford is on other investor (relative to
the person who would otherwise hold the equity). It seems Oxford could largely
negate the signalling effect by making it clear that while it will invest in any listed
company, it doesn’t condone the manufacture of cluster bombs, and that in fact it
wants to exert an ethical influence on Northrop through shareholder activism.
58
(USSIF, 2010)
92
7.3.6. Conclusion
Replaceability in investing is similarly complex – it’s not clear that buying the
equities of harmful companies causes harm, just as it’s not clear that taking harmful
jobs causes harm. There’s reason to think Oxford should actively seek to buy the
equity of unethical companies. The importance of each effect is different from career
choice. Supply-demand effects are close to zero. The important effects revolve
around the effect on Oxford’s investment returns, Political Signalling, the chance of a
boycott, and the potential gains of control.
7.4. Conclusion
The Supermarket Meat (and plane ticket) argument turns out to be misguided due to
the large supply-demand effect. It’s not a good analogy, since there are no job-related
c-consequences and the supply-demand effects are different. Eating the pepperoni
pizza, however, could be the right thing to do. It depends on the details of the other
effects.
The analogy with ethical investing is closer. Rather than suggesting that
replaceability in career choice is a bad argument, it suggests that we should rethink
the practice of negative screening.

8. Conclusion
In seeking an ethical career, it’s not enough just to find a career directly doing good.
In Part 1, I showed that what one does directly gives little indication of the cconsequences of typical career decisions. Understanding these c-consequences is
vitally important. The activities of many careers produce value on the scale of saving
hundreds of lives, so taking one job over another can be a matter of life or death for
hundreds of people. I introduced a Simple Analysis of the counterfactuals needed to
estimate the c-consequences, but showed that this must be replaced with the
Sophisticated Analysis.
Applying the Sophisticated Analysis showed that the c-consequences of typical
career decisions range from none of the good one does directly, to all of it. Taking a
career that directly does good can even have bad-consequences; while taking
harmful careers can make a positive difference. Failing to take account of
replaceability, therefore, means being radically misinformed about the cconsequences of one’s career decisions, possibly to the detriment of hundreds of
people.
We can all agree that it’s morally relevant if one career saves more lives than another.
But in Part 2, I argued that the job-related c-consequences of career decisions for the
ethically motivated are not only morally relevant, but typically determine which
option is ethically preferable: the Dominance Thesis. The other c-consequences of
career decisions are often small for any career. For someone pursuing an ethical
career, they are likely to be outweighed. Similarly, non-consequentialist factors often
95
don’t apply or are outweighed when they do. Replaceability in career choice is not
analogous to other arguments that sound similar, like ‘if I don’t buy this meat,
someone else will.’
This means that an assessment of the c-consequences of different career options, as
determined by replaceability, is enough to work out which option an ethically
minded person should take. So, replaceability is a crucial consideration in choosing
an ethical career.
Despite this, it’s rarely taken into account in ‘ethical careers’ advice. Each year,
thousands of people do not make the most of their ethical career due to a lack of
information about and understanding of replaceability. We need a program of
empirical research, aiming to apply the analysis developed in §4. For each industry,
we need to know about the typical patterns in ability* and opportunity*, whether
entering the industry leads to job-creation, how labour flows between this industry
and others, and so on. The extent to which reallocation of tasks can occur within an
industry is vital. It’s also important to investigate the extent to which the other tools
of economics can be applied to the problem. This will enable us to start to work out
the areas where ethically minded people can have the most impact.
More philosophical work could also be done considering demandingness; as well as
in applying the latest in the ethics of the permissibility of causing harms to career
choice.
96
There are signs of interest in these issues. I hope this interest will continue to grow.
Rather than settle for making a difference with our careers, let’s aim to make the most
difference.
