Abstract
Suppose that two budding scientists, Acheson and Baird, gain entry into a highly selective doctoral programme by attaining the two highest scores in the entry examination. Acheson managed this feat only because she used a cognition-enhancing drug – a drug that allowed her to concentrate more intensely than all other candidates. Baird succeeded without such pharmaceutical assistance. Her success was chiefly attributable to her exceptionally conscientious and efficient preparation.
Now suppose that two cyclists, Campbell and Donoghue, tie for first in the Olympic road race. As a result, each receives many accolades and attractive sponsorship deals. Campbell’s exceptional performance was due in part to his use of a new doping substance; Donoghue’s was achieved without doping.
Many would find the pharmaceutically assisted achievements of Acheson and Campbell to be problematic in a way that those of Baird and Donoghue are not. Some have been prepared to generalize from such cases to other enhancements – that is, other biomedical interventions intended to augment human capacities from an already healthy, disease-free level. They have argued that enhancements are
In what follows I introduce and scrutinize a view that I believe underpins much of this opposition to enhancements. This is the view that (
The term ‘success’ is to be understood here as referring to achievement. Two individuals attain the same success if they achieve the same things. ‘The goods associated with that success’ is to be understood as referring both to the achievement itself, if achievements are in themselves good for the achiever, and to any other prudential goods that the achievement confers on the achiever.
The desert thesis has often remained implicit in philosophical discussions of enhancement, and an initial aim of this article is to bring it to the surface; in the first section, I clarify the thesis, and in the second section, I explain why it is worthy of philosophical attention. My primary aim, however, is to
Clarifying the desert thesis
The desert thesis requires three clarifications. These concern (i) the concept of desert that it invokes, (ii) the assumptions about the genesis of achievements on which it is grounded, and (iii) its scope.
First, the concept of desert. The desert thesis makes a claim about the relative desert of two groups of people – those who succeed with the aid of enhancements, and otherwise similar individuals who succeed without enhancements. I have said what this desert is desert
In one commonly deployed sense of desert, to deserve a good is to be entitled to it. If I purchase a non-counterfeit lottery ticket bearing the number 14,376, and this number is subsequently drawn in the lottery, then I am entitled to the prize – I deserve it, in the entitlement sense of desert. But there is another sense of desert in which I may not deserve it: I may not be
The desert thesis, as I understand it, makes a claim about desert-as-worthiness, not desert-as-entitlement. It holds that those who succeed with the aid of enhancements are generally less worthy of the goods associated with that success than similar individuals who attain the same success without enhancements.
The distinction between desert-as-entitlement and desert-as-worthiness is sometimes equated with a distinction between institutional and pre-institutional desert (e.g., Feinberg, 1970: 55–87). The thought is that entitlements depend on prevailing legal and other institutional arrangements, whereas worthiness does not. However, worthiness can also depend on institutional context. Consider the case of a sporting competition. We can distinguish between the athlete who is entitled to a prize under the rules and conventions governing how the prize should be allocated, and the athlete who is most worthy of this prize. But it is not the case that the latter athlete could be identified without regard for the rules and conventions of the sporting competition. For instance, one factor that is clearly relevant to determining who is worthy of the prize is what the conventionally determined purpose of the competition was. If the purpose of the competition was to test innate running ability, then we may be inclined to say that possessing a high degree of innate running ability is at least one of the factors that could make one worthy of the prize. By contrast, if the point of the competition was to test effort, then innate running ability may be irrelevant to worthiness (Cummiskey, 1987: 18). 2
Thus, though my focus in what follows will be on worthiness, not entitlement, it does not follow that I will be interested only in a pre-institutional kind of desert; indeed, my argument will at several points rely on the dependence of desert on institutional context.
My second clarification concerns the comparison that the desert thesis draws between those who succeed with the aid of enhancements and the otherwise similar individuals who succeed without enhancements. The thesis holds that the ‘enhanced achievers’ generally deserve the goods associated with their achievements less than the comparator ‘unenhanced achievers.’ As I will sometimes say, omitting reference to the relevant goods and dropping the ‘generally’ qualifier, the thesis holds that enhancement ‘undermines desert’ and that unenhanced achievers are ‘more deserving’ than enhanced achievers. However, the thesis tells us nothing about how, despite the similarities between them, the unenhanced achievers manage to realize the same achievements as the enhanced achievers. Do they augment their abilities through means other than enhancement? Do they simply try harder? Or did they start from a higher level of ability than the unenhanced achievers? We will need to assume
Finally, my third clarification concerns the scope of the desert thesis. I limit the scope of the thesis to achievements whose realization without the aid of enhancement contributes positively to the achiever’s desert. That is to say, I limit the thesis to achievements whose realization makes the achiever more deserving of the associated goods than she would have been had she not realized the achievement at all. Not all achievements are like this. Successfully coordinating a terrorist attack does not make one more deserving of any goods associated with doing so; it makes one less deserving of these goods (and, perhaps, more deserving of certain ills). But in many cases, realizing an achievement does make one more deserving of the goods associated with that achievement. This is most clearly so when the achievement is a morally valuable achievement, but it is plausibly also true of some morally neutral achievements. For example, many would hold that one can come to deserve accolades and fame by winning a gold medal at the Olympics, though this achievement is arguably morally neutral, or at least, not very morally significant.
Limiting the scope of the thesis to achievements whose realization contributes positively to the achiever’s desert has the advantage of leaving open two quite different ways in which the desert thesis could turn out to be correct. It could be that employing enhancements generally diminishes the positive influence of realizing an achievement on one’s desert, or it could be that employing enhancements generally makes an independent negative contribution to desert.
Motivating the desert thesis
Having clarified the desert thesis, I am now in a position to explain why I take it as my focus. The thesis has at least three claims to philosophical attention.
First, it yields intuitively plausible verdicts about desert in many cases. Consider what is perhaps the paradigmatic example of enhancement: doping in sport. When one athlete succeeds with the assistance of a doping substance, we would generally intuit that this athlete deserves the rewards associated with his success less than other similarly successful athletes who do not dope. Similar thoughts apply to the use of cognition enhancement drugs by students during examinations. Consider the case of Acheson and Baird, with which I began. Most would judge that Acheson, who used a cognition-enhancing drug, deserves her place on the prestigious PhD programme less than Baird, who did not. This is precisely what the desert thesis would suggest.
Second, the desert thesis, or a restricted version of it, appears to be held, at least implicitly, by some members of the public in social-psychological research. Faber and collaborators presented healthy participants with a scenario in which a protagonist succeeds in completing a cognitively demanding task either with or without the assistance of a cognition-enhancing drug. Participants attributed the success less to the protagonist and deemed the success to be less deserved, when the protagonist had used a cognitive enhancer than when she had not (Faber et al., 2015; Faber et al., 2016). The research subjects appeared to be invoking something like the desert thesis, at least in relation to enhancements of cognition.
Third, though the desert thesis has, to my knowledge, never been straightforwardly asserted in the philosophical literature on enhancement, 3 it is charitable to attribute it to some of those who advance moral or prudential objections to enhancement.
For instance, certain fairness-based objections to enhancement are difficult to sustain without it. Many have objected to enhancements on the ground that they produce unfairness (Douglas, 2007; Fukuyama, 2002: 9–10, 97; Gazzaniga, 2006; President’s Council on Bioethics, 2003: 131–134, 280–281; Rose, 2006: 303; Savulescu, 2006; Schermer, 2008b). In some cases, the concern is about unfair inequalities that might result from unequal access to enhancement technologies or about straightforward cheating – the breaking of rules or conventions that others respect. However, others worry that enhancements will generally (
The desert thesis can, when conjoined with some prominent accounts of fairness, explain why enhancement will generally produce unfairness even in such cases. The relevant accounts of fairness hold that fairness, or one species of it, requires that goods are distributed across individuals in proportion to the degree to which those individuals deserve those goods (Feldman, 1995a; Kagan, 2012: 351). 4 Thus, it is unfair if I have twice as much of some good as you though we are equally deserving of it: fairness then requires that, if possible, we enjoy the same amount of this good. It is also unfair if I have the same amount of that good as you though you deserve it more: fairness then requires that, if possible, you enjoy more of that good. 5
Suppose that you and I succeed in the same way and enjoy the same rewards as a result. But suppose that I realized that success with the aid of an enhancement, whereas you did not. In all other respects, we are similar. For example, we were, in advance of realizing the achievement, equally well off and equally deserving of the rewards we both go on to receive. If the desert thesis holds, then, having both realized the achievement, you are more deserving than me, and it is unfair that we in fact enjoy the same rewards; fairness requires that, if possible, you enjoy greater rewards than me. By contrast, had I realized the achievement without the enhancement or simply not realized the achievement, there is no reason to suppose that any unfairness would have been present between us. My use of the enhancement has had a fairness-disrupting effect.
This is not to say that my use of the enhancement has caused an increase in unfairness
The desert thesis also helps to make sense of another oft-heard objection to enhancement. Opponents of enhancement sometimes invoke the claim that achievements accomplished with the aid of enhancements lack (some of) the value normally attached to achievements of the same kind. For instance, Eric Juengst wonders whether achievements realized via enhancement might be ‘hollow accomplishments’, while the President’s Council on Bioethics claimed that enhancements would undermine the ‘dignity’ of human performance and perhaps render that performance ‘false’ (Juengst, 2000: 39; President’s Council on Bioethics, 2003: 131, 140).
In some cases, enhancements may devalue our achievements because they frustrate the very purpose of the activity being pursued; using an enhancement might, to take an oft-cited example, be like completing a marathon with the aid of roller skates (Whitehouse et al., 1997: 18). Some activities – like marathon running – fulfil their purpose only where pursued in a certain kind of way, and, in some cases, enhancement is inimical to the required manner of execution.
However, not all activities are such that their purpose is undermined when they are pursued with the aid of enhancements (Douglas, 2007; Mehlman, 2004: 493; Roache, 2008; Santoni de Sio et al., 2014; Schermer, 2008a, 2008b). Consider landing an airliner or performing a surgical operation. The purpose of these activities is to realize a certain outcome, and the realization of that outcome need not be threatened, and may even be aided, by the use of enhancements. Nevertheless, some present the concern about devaluing achievements as a
The desert thesis is able to explain why enhancement might deprive an achievement of some of its value even if the activity being pursued by the enhanced individual continues to serve its valuable purpose. It is often thought that normally valuable evaluenda can lack their normal value when they are not deserved (Brentano, 1969: 149; Feldman, 1995c). 7 Pleasure is normally valuable, but some would maintain that it lacks some or all of its normal value when it is not deserved. It is plausible that similar thoughts apply to the goods associated with achievements. It may be that the value of these goods diminishes as the degree to which they are deserved decreases. Thus, if enhancements undermine desert in the way the desert thesis claims, we can expect the achievements that they enable to lack some of their normal value, as proponents of the present objection maintain.
I believe that it is charitable to impute the desert thesis to many of those who have claimed that enhancement generally produces unfairness or devalues our achievements. However, even if this is not so, the fact that the desert thesis provides one plausible way of supporting those widely advanced claims gives us some reason to at least entertain it as an ethical hypothesis. Let us now turn to testing that hypothesis, which I propose to do by examining three candidate justifications for it. The first of these is what I call the argument from immoral means.
The argument from immoral means
Many believe that enhancement is always morally undesirable in a way that education, training and the mere exertion of effort are not. I have suggested that some of this opposition is grounded on the desert thesis. But some is clearly not. Some believe that enhancements are undesirable for independent reasons, for example, because they alienate the enhanced individuals from their true selves (Elliott, 2004; Glannon, 2001: 81–82; Parens, 2005; President’s Council on Bioethics, 2003: 252–260, 293–295), restrict their freedom or autonomy (Habermas, 2003: 64–90), express an ugly desire for mastery (President’s Council on Bioethics, 2003: 287–290; Sandel, 2007: 46, 85), undermine social solidarity (President’s Council on Bioethics, 2003: 56; Sandel, 2007: 89–91) or poison healthy family and romantic relationships (Parens, 2005; President’s Council on Bioethics, 2003: 50–51, 54–55; Sandel, 2007: 45–62). Let us suppose, for the sake of argument, that at least one of these criticisms is sound – that enhancements are always morally undesirable in some desert-independent way that education, training and the mere exertion of effort are not. In this case, we will have a ready justification for the desert thesis, for it is plausible that the adoption of morally undesirable means tends to diminish one’s desert. 8
Thus, suppose that Ewart wins Olympic gold in figure skating, but he wins only because he previously assaulted and seriously injured one of his competitors. Or suppose that Ferguson wins a Nobel Prize in Medicine, but she wins only because she ruthlessly exploited her junior staff. Intuitively, these individuals deserve the goods associated with their success less than the typical Olympic gold medallist or Nobel Prizewinner, and one explanation for this appeals to the fact that each realizes the achievements through morally undesirable means. If the employment of enhancements is always in one way morally undesirable, then similar reasoning could be applied to achievements realized with the assistance of enhancements.
The difficulty with this approach to defending the desert thesis is that it relies on the existence of an independent (of desert) basis for supposing that enhancements are morally undesirable. To establish that any
Let us turn, then, to consider whether it is possible to defend the desert thesis in a way that does not diminish its dialectic significance in this way.
The argument from diminished effort
A second argument for the desert thesis is suggested by the claim, sometimes advanced as an objection to enhancement, that enhancements make our achievements ‘too easy’. Ronald Cole-Turner worries that The new means [of augmenting normal human capacities], such as psychopharmacology and genetic alteration, are perhaps more efficient or easier than the traditional means. But for that reason, they should be opposed…There is, after all, a glory and a dignity in human accomplishment attained the “old-fashioned way,” through sweat and struggle, sometimes against great odds. (Cole-Turner, 2000: 155) in those areas of human life in which excellence has until now been achieved only by discipline and effort, the attainment of those achievements by means of drugs, genetic engineering, or implanted devices looks to be “cheating” or “cheap.” We believe – or until only yesterday believed – that people should work hard for their achievements. “Nothing good comes easily.” Even if one prefers the grace of the natural athlete, whose performance deceptively appears to be effortless, we admire those who overcome obstacles and struggle to try to achieve the excellence of the former….(Kass, 2003: 21. See also Sandel, 2007: 25–26; Tobey, 2003: 113–114, 120–124).

It would be tempting to say, regarding this case, that Hamilton is in one way more deserving of the goods associated with his achievement than Gibbs. This is not to say that he is all-things-considered more deserving – some would argue that, perhaps since sports are designed in part to test or display natural ability, one of the things that can make one deserving of sporting success, and associated rewards, is precisely the kind of natural ability that Gibbs possesses. But there seems to be something pulling in the other direction also. There seems to be some respect in which Hamilton
Consider now a second case, this time involving the use of a (let us suppose) permitted enhancement. Irvine and Jardine have roughly equal innate running ability and have trained equally hard. They both complete a marathon in just less than 3 hours – much faster than either has run previously. Irvine’s unusually quick time is due to her pushing herself exceptionally hard during the race; Jardine’s is attributable to her having taken a blood-thickening dietary supplement in the weeks leading up to the race. Again, we might be tempted to say that Irvine deserves any success associated with her achievement more than does Jardine. And again, we might posit that this is due to Irvine’s greater exertion of effort.
We can generalize from this case. It is not a coincidence that Jardine employed an enhancement
This argument – the argument from diminished effort – may seem susceptible to a quick response: in some cases, enhancements lead the enhanced individual to exert
I believe that this quick response may be sufficient to undermine the argument from diminished effort, but I will not pursue it here, for two reasons.
First, it applies only to a rather narrow range of enhancements. This response may show that
Second, the quick response is susceptible to a possible objection. The objection holds that what matters for desert is not the absolute level of effort that one exerts, but the level of effort one exerts relative to one’s potential for exerting effort. What matters, in other words, is the degree to which one realizes this potential. If ‘potential for exerting effort’ is understood so as to incorporate all biological influences on the level of effort that one in fact exerts, then enhancements, whose effects are biological, must operate by augmenting potential for exerting effort, rather than the degree to which this potential is realized. On the present objection, this will confer no increase in desert.
I do not wish to endorse this objection – indeed, I think its prospects are not rosy, for reasons I have pursued elsewhere (Douglas, 2014a). Still, if we could offer a response to the argument from diminished effort that evaded this sort of objection, that would be preferable, and as it happens, I believe that we can do just that.
Rather than employing the quick response, which holds that some enhancements augment effort, I will pursue an alternative line of response to the argument from diminished effort. My response concedes that enhancements undermine effort, but maintains that they nevertheless need not undermine desert.
The response begins from the observation that, in some circumstances, adopting a lower effort route to some achievement has no negative effect on one’s desert for the goods associated with that achievement (Schermer, 2008a: 359–360). One such circumstance is where an agent has the option of realizing the achievement via either a lower or a higher effort route, and there is no more reason to pursue the higher effort route than the lower effort route. In such a case, adopting the higher effort route involves exerting gratuitous effort – effort that there is no more reason to exert than not – and it would be at the very least puzzling if gratuitously doing things the hard way could make one more deserving of goods (Douglas, 2014b; Milne, 1986: 240). 11
Suppose, then, that two similar agents face a choice regarding how to realize some achievement. They can either employ an enhancement or a more effortful traditional route involving, say, extra training. Both options are available to both agents, and the agents are aware of the amount of effort that each route to the achievement entails. The first agent chooses to employ the enhancement; the second adopts the more traditional route.
If there is no more reason to abstain from the enhancement than to pursue it, then the second agent, who eschews the enhancement, is simply exerting gratuitous effort, and exerting gratuitous effort cannot make one more deserving. 12
Of course, in many circumstances in which enhancements are used, there may be reasons to adopt a higher effort route. For example, if we think that part of the point of sports is to elicit extreme levels of effort, then the athlete may well have reasons to eschew effort-reducing enhancements. However, if this is the case, we already have an independent (of desert) objection to pursuit of the enhancement. Thus, we are back with the problem faced by the argument from immoral means. The appeal to diminished effort will succeed in establishing that a
Two possible responses to this suggestion need to be considered. The first maintains that the effort exerted in avoiding an enhancement is rarely gratuitous, because effort almost always has the instrumental value of helping to cultivate a disposition or ability to exert (nongratuitous) effort in the future. Exerting effort, it might be said, is generally character-building. Yet even if exerting effort did generally conduce to desirable forms of psychological development, a claim that has been questioned (Forsberg, 2013: 168–169; Schermer, 2008a: 357–358), there is no good basis for assuming that reasons to pursue such psychological development will always, or even typically, be decisive. After all, exerting effort also has predictable costs. Realizing a given achievement via a more rather than a less effortful route will, for example, tend to diminish one’s ability and willingness to realize other valuable goals.
The second response maintains that even gratuitous effort makes one more deserving. Certain intuitive reactions might seem to support this view. Suppose that Kerr and Lester independently make the same scientific discovery. Both relied on the same sophisticated piece of statistical software in making this discovery, however, as an additional challenge, Kerr had one of her colleagues program a number of bugs into the software. Thus, Kerr had to overcome a number of software glitches to make the discovery, whereas Lester did not. Kerr had to exert more effort. Suppose, moreover, that any reason Kerr had to exert this effort in order to develop desirable character traits was outweighed by countervailing reasons: perhaps, for example, the effort of overcoming the software bugs also drained her energy in a way that predictably impaired her ability to produce other smaller scientific insights in the course of making her chief discovery.
Although I do not share the intuition myself, I concede that some might wish to claim that Kerr deserves more praise for her achievement than Lester, even though the extra effort she exerted appears to be gratuitous.
It is not clear, however, that this intuition supports the view that gratuitous effort can confer desert, for we can accommodate the intuition without endorsing that view. We may take Kerr to be more deserving of praise than Lester because we take her exertion of gratuitous effort as evidence that had a greater level of effort been necessary to realize the achievement – say, because only buggy software was available – she would have exerted it. This would suggest that it is the counterfactual exertion of nongratuitous effort by Kerr that confers her greater desert, not her actual exertion of gratuitous effort (Douglas, 2014b).
Thus, it is possible to explain the intuition that Kerr is more deserving than Lester without attributing a desert-conferring effect to gratuitous effort, and since it would be at the very least puzzling if gratuitous effort could confer desert, we should tentatively accept this alternative explanation.
I take it, then, that exerting gratuitous effort confers no desert. It follows that, for any given enhancement, there is either an independent (of desert) objection to the pursuit of the enhancement, thus deflating the dialectic significance of the claim that the enhancement undermines desert, or the appeal to diminished effort fails to establish that the enhancement undermines desert, since the effort exerted through eschewing the enhancement would have been nongratuitous.
The argument from shared responsibility
A third argument for the desert thesis is suggested by another claim sometimes advanced as an objection to enhancement. Daniel Tobey writes that With enhancement we achieve an end not through struggle but with the ease of one selecting an item from a menu – it is the difference between cooking a meal and ordering in. The purchased meal might taste better objectively, but it is not
Responsibility should, for the purposes of this discussion, be understood as attributability (Watson, 1996).
14
An agent
I take it, then, that Tobey is suggesting that use of enhancements generally diminishes the degree to which the resulting achievements can be attributed to the agent who undergoes the enhancement. Why think that enhancement diminishes responsibility in this way?
One thought might be that the responsibility of enhanced achievers is diminished because some responsibility for the achievements that they realize lies elsewhere – it lies with the designers (and perhaps also the prescribers) of the enhancement. A parallel point can be made regarding the use of external technologies in certain sports: Consider the yachtswoman who wins a regatta because her friend loans her an especially fast boat, or the Formula One driver who wins a grand prix because his team provides him with the fastest car available. We might be inclined to say that these competitors are less responsible for their victories than they would have been had they realized them with a standard yacht and car, respectively, because more of the responsibility for their achievements is borne by others: the designers and providers of the assistive technologies. The proponent of the present claim takes a similar view about achievements enabled by enhancements: The responsibility of the enhanced achiever is reduced because that responsibility is shared with, for example, the designers and distributors of the enhancement technology.
If the partial responsibility of others generally diminishes the responsibility of enhanced achievers for the achievements they realize, then we will, I think, have a plausible argument for the desert thesis. Sometimes, realizing an achievement confers desert in the sense that, through achieving something, the achiever comes to deserve (some of) the goods associated with the achievement, or to deserve them to a greater degree. As noted earlier, this is not always so: for example, realizing
If the use of enhancements generally reduces one’s responsibility for one’s achievements, then there is a
Let us consider two candidate justifications. The first holds that responsibility is zero-sum: for any achievement, there is a fixed amount of responsibility to go around. Thus, if the designer of an enhancement is partly responsible for a post-enhancement achievement, the user of the enhancement is necessarily not fully responsible for it.
This justification has unacceptable implications. Suppose that
The claim that responsibility is zero-sum has implausible implications. Let us turn, then, to the second candidate justification for the view that the use of enhancements reduces responsibility. This justification holds that, when you use an enhancement to achieve some outcome, you ‘outsource’ some of the agential processes required to bring about that outcome; you employ someone else to invest her agency in realizing the achievement, and in doing so you diminish the role played by your own agency. Thus, the achievement is less an expression of your agency than it would otherwise have been. When the Formula One driver accepts the faster car from his team, it is not just that he allows the agency of others to influence his level achievement, he reduces the call for investing his own agency. Without the faster car, he would have had to train harder, or make better tactical decisions, to achieve the same result. Perhaps those who realize achievements with the aid of enhancements can also be thought of as outsourcing some of the agential tasks required to realize an achievement.
This justification – the ‘outsourcing justification’ – also runs into difficulties, however.
An initial response to it would mirror the ‘quick response’ to the argument from diminished effort that I considered in the previous section. Even if outsourcing agential tasks would in one way tend to diminish the role played by the enhanced person’s own agency in realizing an achievement, it might in other ways tend to augment her investment of agency: for example, the enhancement may operate by augmenting the agential resources that the enhancement user has available to invest (Santoni de Sio et al., 2016). This will most obviously be so in relation to enhancements that diminish psychological impediments to the exercise of agency. Suppose you face a choice between several alternative courses of action, but suppose you have a number of false beliefs about the nature and likely consequences of these options. Suppose also that you are subject to a number of impulses that might lead you to take an option other than the one you reflectively endorse. These false beliefs and impulses are plausibly impediments to your agency. But a cognition enhancement might help to correct these false beliefs, and a motivation enhancement might attenuate these impulses. A possible upshot of either enhancement would be that your decision becomes more reflective of your agency and less reflective of impediments to it.
As with the quick response to the argument from diminished effort, I believe that this response may be sufficient to refute the outsourcing justification, and thus, the argument from shared responsibility, but, also as with that response, it will apply to a rather narrow range of enhancements, and it may be susceptible to the objection that what matters is not absolute investment of agency, but investment relative to one’s potential to do so. For these reasons, I pursue an alternative response to the outsourcing justification – one that applies more generally and is not susceptible to this possible objection.
My response begins from the observation that, on the outsourcing justification, it is not ultimately the enhanced individual’s increased reliance on others’ agency that diminishes her responsibility, it is her decreased reliance on her own agency. On the outsourcing justification, then, cases of enhancement are relevantly similar to cases in which a person is less reliant on her own agency not because she has deployed an enhancement, or otherwise outsourced a task to someone else, but for some other reason: for example, through good fortune of circumstance. The scientist who employs a cognitive enhancement and thus diminishes the need to exert her own agency in her work is, from the perspective of the outsourcing justification, equivalent to a scientist who, through no good planning of her own, happens to find herself in an inspiring and distraction-free environment; an environment that allows her to make scientific progress with less need to invest her own agency than a comparable scientist in less favourable conditions. Note, however, that we would not normally regard an individual as less responsible for her achievements, in the sense that the achievements are less attributable to her, merely because she, though good fortune, finds herself in more favourable conditions and thus with less need to invest her own agency.
There are at least two plausible explanations for why reduced investment of agency does not necessarily reduce responsibility. On the first explanation, full responsibility is retained as long as the investment of agency surpasses some threshold. Thus, there is a range over which a reduction in agency invested confers no reduction in responsibility. On the second explanation, only a certain
Both of these explanations for why reduced investment of agency need not reduce responsibility could be invoked in relation to some enhancements. Even where enhancements involve outsourcing tasks to others, thereby reducing the need for the enhanced individual to invest his own agency, they may nevertheless leave the enhanced individual above the threshold level of agency-investment required for full responsibility on the first explanation. And provided that the enhancer continues to exercise his agency in, for example, deciding how to employ enhancements, or the abilities that they confer, he may retain the kind of executive control required for full responsibility according to the second explanation.
Reflection on cases in which the call for agential investment is diminished by accidents of circumstance suggests that the cases in which enhancements diminish responsibility by diminishing agential investment will be rare. In most cases, those who, through good fortune, enjoy extremely favourable circumstances nevertheless retain full responsibility, in the sense of attributability, for their achievements, suggesting that only a modest level of agential investment or executive control is required for full responsibility. This suggests that most enhancements will also preserve full responsibility.
Implications
I have assessed three arguments for the desert thesis. I argued that the third of these – the argument from shared responsibility – fails to justify the thesis: It is not the case that enhancements generally diminish responsibility; indeed, I have just suggested that in most cases they do not. By contrast, I allowed that the first two arguments – the argument from immoral means and the argument from effort – might succeed. However, I argued that they succeed in showing that an enhancement undermines desert only in those cases where there is already an independent objection to the enhancement, and in these cases, the appeal to desert loses much of its dialectic interest.
It is possible, of course, that there is some other argument for the desert thesis that I have missed. However, it is not clear what this argument could be, and the literature on the ethics of enhancement is of little help here. 16 In that literature, the desert thesis typically functions as a premise (usually implicit), not as a conclusion, and when authors sympathetic to the desert thesis have alluded to considerations that might support it, they have alluded to the argument from diminished effort and the argument from shared responsibility.
Let us thus tentatively assume that we have assessed the only credible arguments for the desert thesis. This leaves the proponent of the thesis with two options. First, she can rely on the argument from shared responsibility and accept that there is no rational basis for the view that enhancement generally undermines desert, or indeed for the view that it does so in any more than a very narrow range of cases: Most enhancements preserve full responsibility. Second, she can turn to either the argument from immoral means or the argument from diminished effort. However, she is then forced to concede that the desert thesis either fails (because there is no general independent objection to enhancement) or has little dialectic significance (because there is such an objection). Moreover, she is then forced to concede that desert-based explanations for why any
Nevertheless, my argument does draw attention to some cases in which use of enhancements will undermine desert. One of these cases is where the enhancement dramatically diminishes the investment of agency on the part of the enhanced individual. Another is where the enhancement reduces the amount of effort that the enhanced individual exerts but there were, in fact, good independent reasons to exert that effort. One such case will be where the enhancement is employed in the context of an activity whose value lies, at least in part, in its effortfulness (which I suspect is true of many sporting endeavours); in such contexts, there
