In enhancement ethics, evolutionary theory has been largely perceived as
supporting liberal views on enhancement, where decisions to enhance are
predominantly regulated by the principle of individual autonomy. In this
paper I critique this perception in light of recent scientific developments.
Cultural evolutionary theory suggests a picture where individual interests
are entangled with community interests, and this undermines the
applicability of the principle of autonomy. This is particularly relevant for
enhancement ethics, given how – I argue – decisions to enhance are often
influenced by desires to increase social status. The “service view on
enhancement”, based on principles of service and trust, is proposed as
offering better guidance for the challenges of social living.
1. Introduction
Science may be neither necessary nor sufficient for ethical argumentation; nonetheless,
evolutionary theory has played a prominent role in recent enhancement ethics. For
instance, claims that enhancement should be constrained by a fixed human nature or by
givenness seem difficult to hold given how the human species evolved and continues to
Another evolutionary argument that seems to have gained particular currency
appears to offer a direct, positive argument for enhancement. It appeals to the fact that
humans evolved in hunter-gatherer environments but live in cosmopolitan and urbanized
environments with which they are mismatched. This is a major hypothesis in evolutionary
psychology and psychiatry, and is linked, for instance, to the widespread prevalence of
some mental health disorders.
In the context of enhancement ethics, the mismatch
hypothesis is leveraged to argue that humans are so deeply maladapted, unable to rise to
the challenges of cosmopolitan and multicultural environments, that only technological
enhancement can ensure that humans are fit for the future. Hence many legal and
institutional barriers constricting enhancement should be lifted, so that enhancements
can be used in the quest for personal well-being.
It is striking how, through such arguments, evolutionary theory has broadly been
perceived as supporting liberal views on enhancement, where decisions on whether to
enhance or not are predominantly guided by the principle of individual autonomy. And
while liberal views can range from the social liberal to the libertarian, in enhancement
ethics, the center of gravity in recent literature has tended towards the latter. According
to libertarian views, enhancements are to be judged as Millian “experiments in living”: as
long as they do not actively harm others, they are ethically commendable expressions of
individual autonomy.
A libertarian view on enhancement may not convince everybody, but it is not
always easy to show where precisely the view goes wrong. For once one accepts that
humans are deeply maladapted, it is very difficult to escape the logic of utilitarian
reasoning, which leads inexorably to the conclusion of liberalizing enhancement in one
way or another, if not through legal and institutional deregulation (the libertarian
conclusion), then through fair, institution-backed administrations of enhancement (the
social liberal conclusion).
My aim in this article is to undermine the starting point in this reasoning by
drawing on cultural evolutionary theory. This shows how the role of the social and cultural
environments has been unjustifiedly ignored or downplayed in recent enhancement
ethics. The implication is an undermining of the fundamental presumption of liberal
views: a relatively strong distinction between the interests and decisions of the individual,
and those of the community. It is just this distinction that is undermined given what we
know about how our species evolved. As a very social species, our desires are significantly
shaped by the norms and patterns of behavior of the community we inhabit. Our desires
are not quite “our own”.
One very concrete dynamic that illustrates this intertwining of individual and
community is competition for social status. The desire for status, as we will see later, is
fundamental motivator for humans, regardless of culture, gender, age, or even
personality. Unsurprisingly, this motivator also appears across empirical studies on
attitudes towards enhancement. From height enhancements to performance enhancing
drugs and cognitive enhancement, decisions to enhance are often motivated by desires to
increase social status – potentially leading to perverse status competition.
This dynamic does not so much falsify liberal views as show them to be incomplete.
I argue that neither the principle of no harm nor that of distributive justice gives
satisfactory guidance to individuals navigating such status competition. Deliberations on
whether to enhance thus require ethical resources not found among liberal views.
What could be more promising instead? I propose the service view on
enhancement, in which the dominant principle guiding individual decision making is not
autonomy but service: not the “own” good and wellbeing in the strict sense, but the good
and wellbeing of others and that of the community at large. This view is, I argue, more
grounded on what we know about human evolution, and is also more in tune with the real
concerns, anxieties, or competitive urges that members of communities must respond to.
2. Evolution and Liberal Views of Enhancement
Enhancement ethics is future oriented. It is about what humans might become.
Unsurprisingly, therefore, it has long been inspired by the science of what humans have
been in the past—namely, evolutionary science. The old eugenics was strongly inspired by
the 19th century understanding of the theory of natural selection;
similarly, today’s
enhancement ethics draws on two common evolutionary arguments. The first argument
turns on the fact that evolution debunks (folk-psychological) essentialist understandings
of human nature.
There are simply no universal, unchanging properties that characterize
all members of the Homo sapiens. Hence enhancement technology is not changing
anything that might not change anyway. Beliefs in (essentialist) human nature are
ungrounded and should not constrain enhancement.
Is this debunking of human nature
definitive? Not necessarily. In the past decades there have been some attempts to
resuscitate human nature as a scientifically legitimate concept.
However, the resulting
concepts of human nature are causal or descriptive concepts, void of moral significance.
A similar argument has also been applied to the concept of “givenness”.
After all,
humans have been technologically enhancing their “given” capacities since the dawn of
the Homo genus about two million years ago. Our evolutionary history paints us as
enterprising, autonomous individuals; there is no natural or given state of affairs to
constrain human autonomy. Human enhancement is business as usual.
If the first evolutionary argument supports the right to enhance, the second
evolutionary argument – and the main focus of this paper – supports to duty to enhance.
In brief: the vast majority of the evolution of the Homo genus (i.e., about 99.5% of the
past 2 million years) took place in an environment of small-scale hunter-gatherer
societies, and today human traits and human cognition remain designed for the specific
challenges of that ancestral environment. This hypothesis has been used to great success
in evolutionary psychology to explain common mate preferences, sexual taboos, and
and why some mental disorders, such as major depressive disorder or
attention deficit disorder, seem to be on the rise.
This hypothesis has been used in
enhancement ethics to provide an argument in favor of enhancement or, at least, for
enhancement of any trait that is not optimally adapted to the challenges of our urbanized,
anonymous, and increasingly online living.
Here is one concrete instance of this mismatch argument:
After all, our brains are products of evolution, which is a blind process that hardly
seeks to maximize the good, or make us morally best. Evolution ‘cares’ only about
reproductive success. Moreover, even if the evolutionary process somehow led to
what is in one sense an optimal result, this result may be optimal only in the
environment in which our very distant ancestors lived. It is very unlikely to be
optimal in our utterly different modern environment. (There was, for example, no
police in the primeval savannas, nor were there planes or hijackers . . .)
Other examples could be cited,
and variations on this positive evolutionary argument
have been widely adopted by prominent ethicists.
The mismatch argument works in part through its rhetorical force. One barrier to
widespread acceptance of enhancements progress might lie in our evolved cognitive
biases, such as biases towards the status quo,
somewhat similar to how the eighteenth-
century philosopher Nicolas de Condorcet thought the barriers to human progress lay in
“ignorance” and the “yoke” of political or religious authority.
The mismatch argument
creates the impression that liberal views of enhancement are situated within a larger
family of liberal views that go back to the Enlightenment. The rhetorics of this association
lies in the suggestion that, also today, the liberalization of enhancement must overcome
similar trials in human obscurantism and irrationality.
In terms of its logic, the mismatch argument seems to work in two ways. First, it
shifts the utilitarian calculus in favor of enhancement: the current state of human
phenotypes is very maladapted, and this maladaptedness is engrained in our genetic
makeup, and hence the potential benefits from enhancement are very large. In other
words, the argument supports “enthusiasm” for enhancement, where the relative benefits
of enhancement are emphasized.
However, such a utilitarian calculus could also be used
to justify a collectivist approach to enhancement, so the maladaptedness argument must
do more than simply shift the utilitarian calculus in favor of a liberal (and specifically
libertarian) view on enhancement. (Note that the argument for enthusiasm works best if
human phenotypes are suboptimal, but not too suboptimal; if our desires and volitions
are too deeply maladaptive, then the principle of individual autonomy is eroded and a
societal decision to let the decision be made by hard data and algorithms will compel us
to accept enhancement, perhaps even the radical enhancement of transhumanism.
A second and more fundamental way in which the maladaptedness argument
promotes a liberal view perhaps lies in how it paints a direct, simple, and intuitive view of
humans and human evolution as “individual-centered”. In such a individual-centered
view, adaptiveness is spelled out in terms of capacities of the individual not social or
moral norms, or social structures. The unit of selection is the individual, and the only
processes considered are those concerning the individual and the individual’s direct
The individual-centered view does not explicitly reject group selection or cultural
evolution; it just ignores it. It is perhaps best understood as a certain interpretation of the
evolutionary psychology of the 1980s and 1990s,
and fits in well with approaches to
defining well-being in terms of individual capacities and changes in well-being in terms
of changes in "the biology or psychology of a person"
. This focus on the individual comes
under pressure when we consider how entangled individual interests are with community
3. Social Status and the Decision to Enhance
When a human and chimpanzee toddler are given the same spatial or causal task to solve,
they do about as well (or rather, poorly). However, when it comes to social tasks, like
imitating the human experimenter's solution of following their gaze, then the human
toddler vastly outperforms the young chimpanzee.
This phenomenon of imitation and
social learning is the crucial feature of cultural evolutionary theory’s view on human
The human evolutionary story is a story of social learning, in which
knowledge and skills are transmitted from one individual to the next and from one
generation to the next via social processes.
Social learning is thought to be central for
the dramatic geographic expansion and population growth of the human species.
This gives rise to what can be called the “group-centered view” of human evolution,
in which the community or group is the central unit of selection, adapting to changes in
the external environment and undergoing selective competition. Individuals develop in
social-cultural environments, and the structure of the latter changes over time: new
behavioral habits, moral norms, and technological know-how. The community affects
individual reasoning and valying, which in turn affect social norms, and in this way, our
actions in the private sphere undertaken in our “experiments of living” are proto-
public acts with ripple effects throughout the community.
Social Status Norms. I will be arguing that one type of social norm in particular
status norms seems to be highly relevant for understanding decisions to enhance. For
this it is helpful to have some background in evolutionary perspectives on status, because
the term “status” may evoke predominantly negative connotations today (oppression,
privilege, structural violence, and so on). From an evolutionary perspective, “status
differences” refers to ways of structuring a group of organisms so that intragroup conflict
about access to resources is minimized. For example, the pecking order among chickens
allows a group of chickens to work out which individual may peck at food first, which
individual second, and so on, without physical conflict. Such hierarchies are widespread
among mammals, birds, fish, as well as invertebrates
– and humans.
The main difference between the human and other animal species lies in how
human status hierarchies are determined not only by “dominance,” or the threat of force,
but also by “prestige,” which is freely given to individuals in recognition of a high degree
of competence in some activity.
So humans have evolved ways of shaping status
hierarchies so that status is assigned to the persons whom others can learn the most from,
and also who might likely make the best decisions for the group. Status competition, as
long as it is for prestige, need not be zero-sum, as it can lead to better services being
rendered to the community. Prestige represents a prosocial way of organizing status
However, like any moral innovation, it can be hijacked. High-status individuals
hold sway over large swathes of the community, and hence at some later time they can, in
principle, convert their social networks into coalitions to suppress a rival.
dominance behaviors lurk around the corner, even if status was originally freely conferred
to the individual. Hence human societies are characterized by “service-for-prestige”
norms: high-status individuals are expected to provide some form of service (expertise,
risk, judgment, time) in exchange for prestige, and are punished if they fall afoul of the
In this way, most if not all human cultures are characterized by a constellation of
service-for-prestige norms – something that I will dub the “ethos of service” for purposes
here. In reality, this ethos is, of course, not evenly distributed, and some communities
have a weaker ethos of service than others. For instance, apparently the “dark triad” of
dominance-related personality traits (Machiavellianism, narcissism, psychopathy) is
significantly more prevalent among corporate and political leaders compared to the
general population.
Nonetheless, it is not wrong to deem an ethos of service as the norm
for human populations. As suggested by very term "dark triad", the ethos of service is still
held as a normative ideal even if it may not be realized.
Social Status and the Decision to Enhance. Imagine an enhancement that
has as little to do as possible with social status – perhaps a hypothetical drug that allows
one to blink “abnormally” fast, beyond species-typical limits. Why is there no industry
researching and investing in breakthroughs for blinking drugs? Why are lawmakers and
ethicists not debating the acceptability of such enhancements? Because nobody cares:
nothing is at stake. Perhaps some biohacker might find some idiosyncratic interest in such
enhancements, but it is hard to imagine such an enhancement being of any public
Conversely, some of the most ethically controversial classes of enhancement
directly or indirectly involve competition for status. The most straightforward example is
height enhancement. Like almost all other animal species, humans unconsciously assign
higher status to tall or large individuals.
This bias shows up in various statistics, for
instance in correlations between height and military or corporate rank, or between height
and income (Blaker et al. 2013). It also shows up in experimental psychology, with most
marked effects on the judgment of males: taller males are perceived as possessing
superior leadership, intelligence, and even health.
This privileging of height, contrary to appearances, is not merely a quirky vestige
of our evolutionary past. In particular, it shows up in clinical studies and the ethics of
“idiopathic short stature” the condition of short stature without any underlying
pathology. Some parents (consciously or not) view short stature as a “disadvantage in
[the] child’s social life and career” or even as a “disability”.
Perhaps in recognition of
these lived realities, the U.S. Food and Drug Administration sanctions human growth
hormone therapy when the child is in approximately the first percentile for height, even
though the child may not be suffering from a growth hormone deficiency.
What matters here is relative height, not absolute height. In fact, what has counted
as “short” has fluctuated considerably over history,
and the competition for relative
height is an obvious instance of a zero-sum competition. So, to briefly anticipate the
consequences for liberal views, one can already wonder to what extent parents are making
an autonomous decision when they opt for human growth hormone therapy for a short
child even if perfectly healthy. The parents are not being forced to enhance, but at the
same time their calculus is driven by fears that their child will have to face bullying, being
passed over for jobs and promotion, and so on.
The decision is not coercedin any hard
sense, but the norms of the social-cultural environment are setting the parameters for the
parents’ calculus, and one can only assume that most parents would decide differently if
the costs of short stature were not so steep.
A similar story can be told of performance enhancement. In a recent empirical
study of the motivations of athletes to take performance enhancers,
the most
widespread motivations pertained directly athletic performance, even when it came at a
cost to personal health. Why is athletic excellence desired? The researchers document that
there are many second-order motivations that have to do social status: improving one’s
social image, securing respect from others, gaining friends, obtaining what the
researchers term “hero status”, getting more media attention, and acquiring financial
gains. Once again, status norms in the social-cultural environment are setting the
parameters for the decision whether to enhance.
Some types of enhancement undertaken for aesthetic reasons may also have
second-order motivations related to status. For instance, when anabolic steroids are used
as a cosmetic enhancement to increase muscle mass, users point to aesthetic reasons and
the desire for “enhanced confidence”.
But why should having a muscular body be
aesthetic or justify self-confidence? Basic evolutionary psychology tells us here that
humans about muscle mass (at least in males) because, as a way of increasing one’s
physical formidability, it increases perceived dominance status.
How deep is the link between motivations for enhancement and social status? The
rationale for the link between enhancement and status is simply that an enhancement of
some desirable capacity X can be used to either gain a competitive advantage over others
with regards to X (in a competition for dominance) or to provide a better service to the
community through X (and hence increased prestige). The capacity X need not be used in
status competition; however, the reality is that social status represents one of the
fundamental motivators for humans. In their review study, Cameron Anderson et al. even
conclude that our evolved desire for status is a “universal” human motivator: it is
discerned across cultures, genders, ages, and personalities.
Given the centrality of the
status motivation, and given how enhancements can be co-opted for status competition,
one should not be surprised that motivations to enhance are often even be subordinated
to status-related motivations.
One could wonder whether the observation holds for all types of enhancements.
This depends in part on the definition of “enhancement”. Health-related interventions do
not seem to have much to do with status: vaccinations stimulate adaptive immunity, and
glasses correct for myopia. Whether such interventions should be categorized as
enhancement or not is subject to disagreement: some would wish to preserve some
distinction between “therapy” and “enhancement”.
Relationship and love
enhancements also would not seem to be motivated by status, but again, it’s debatable
whether love drugs aim beyond species-typical norms or merely at achieving what is
typically considered “healthy.”
Despite these questions, it is safe to say that status seems central to the motivations
for at least some types of enhancement technology. In such cases, given how individual
interests are entangled with status norms (in which community interests are
represented), the mismatch argument for enhancement seems much less plausible.
Apparent mismatch may be the product of a suboptimal social and cultural environment
– and wayward status hierarchies in particular. which may value properties such as “being
taller than most others” or being more muscular or having shorter feet. The appropriate
response is not enhancement, in order to better adapt to the environment, but rather
social action to change the environment.
This line of thought also casts doubt on the basic libertarian normative idea that as
long as nobody else is harmed by an enhancement, a person should be free to undergo
enhancement in any way they see fit. The problem is not that the libertarian idea is wrong
but that it is fatally incomplete. It does not recognize that individuals desire some
enhancements because they would improve status, and it does not consider that narrowly
pursuing status can lead to zero-sum status competitions in which everyone is left worse
off. The basic libertarian view has a blind spot about perverse status competition.
4. Liberal Responses: No Harm and Justice
The liberal approach to enhancement could be defended against this critique. The
condition that enhancements must not harm others and a requirement for distributive
justice, for example, might allow for liberal views to put limits on enhancements that are
aimed at gaining dominance status. However, the entanglement of individual and
community interests turns out to be fundamentally problematic for any liberal view.
Avoiding harm through moral enhancement. The first defense is the threat
from perverse status competition constitutes a form of harm, and hence can motivate
restrictions on individual autonomy. In fact, our unfortunate, status-oriented moral
psychology could be taken as a reason for carrying out moral enhancement, in order to
suppress our desires for dominance and promote our desires for service. Thus, a liberal
proponent of enhancement might argue, the solution lies not in less enhancement but in
more and better-targeted enhancement.
Usually, moral enhancement is discussed as a potential response to exclusivist
tendencies within our moral psychology: we tend to be negatively biased towards humans
who do not belong to our “group”, defined by culture or ethnicity.
The defense here
applies similar considerations to the distinction between dominance and prestige status.
Just as inclusivist morality has considerable precedent in human evolution, so do service-
for-prestige norms; even so, it could be argued that our concern for the latter could use a
“boost by biomedical means”.
Perhaps prosocial drugs could raise levels of prosocial
hormones or neurotransmitters like oxytocin or serotonin, with the effect that low-status
individuals would not make decisions based on a desire of dominance and such that high-
prestige individuals would use their position to obtain power and impose their wishes.
Why this defense, upon reflection, does not seem attractive lies in the nature of the
concept “service”. What does it mean to “serve” others, rather than to “seek dominance”?
There is sometimes a fine line between service and the pursuit of social dominance. If the
committee chair silences someone during a meeting, then the chair is using their position
of dominance. However, it is not primarily dominance if the act of silencing is done out
of service to the group – for instance if the person was speaking hatefully. But it would be
a pure dominance display if the participant was silenced merely for presenting a
dissenting opinion. This raises the question: who decides what service means, and with
it, what behaviors are to be judged as mere displays of dominance and what as pro-social
Moreover, prosocial tendencies can end up supporting oppressive status norms.
For instance, a moral reformer may be motivated by service and not by dominance, but
may not be perceived as such by the majority if the reformer is viewed as "antisocial" and
as flouting social norms. In this way, the notion of "community interests" is ambiguous.
Does it have to do with respecting preferences of immediate peers, or those of future
generations? This question goes beyond the scope of this article, but the fact it arises
shows how the further strengthening of service-for-prestige norms cannot be
automatically obtained by pharmaceutically enhancing prosocial hormones or
More ethically plausible, though less technologically plausible, would be a form of
moral enhancement that directly improved moral decision-making – a chip or computer-
brain interface, perhaps. At least in theory, such an enhancement could help with the type
of fine-grained decision-making under uncertainty required to promote service-for-
prestige norms. However, once the moral enhancement becomes powerful enough to
actually guide decision-making, then the question arises of who would design such a
moral enhancement? Which values would be programmed into the chip, which ethical
principles? This response to the problem of perverse status competition thus seems to
lead us very far away from the core libertarian idea, and towards, at best, a paternalistic
social liberalism. However, in that case, the designers would need to possess some prior
understanding of service-for-prestige norms in order to design such moral
enhancements. So, for at least a segment of the population, the problem of perverse
competition would not be solvable by moral enhancement.
Distributive Justice. The second strategy is that of a social liberal who never
would have subscribed to the libertarian idea in the first place: in this person’s view, the
danger of perverse competition is a familiar danger associated with positional goods and
a strong rationale for regulation by public policy on grounds of distributive justice.
the social liberal’s view, the state and public institutions should step in to prevent the
worst excesses of status competition and ensure a baseline of fair distribution of goods,
so that basic rights and equality of opportunity are protected. Allen Buchanan and Russell
Powell have recently argued that exclusionary tendencies in our moral psychology require
correction through principles of distributive justice,
and their argument can be
expanded to address the challenges from enhancements that confer social dominance.
In many important cases, this is the right response: when it is in the community’s
interest to have a fair distribution of “social and economic advantages” accruing to
individuals, principles of distributive justice can help address the problems of individual
autonomy that arise if enhancements conferred those advantages.
However, the
primary recipient of the advantages of enhancement is assumed here to be the individual.
The community’s interests in the enhancement are secondary. Sometimes, however, an
enhancement might be considered primarily as a gift to the community, and in these
cases, principles of justice that equally distribute the enhancement are inappropriate.
This can be illustrated with two contrasting examples.
First, consider performance enhancing drugs. Do athletes take these to serve the
community better? Interestingly, some have argued for that the use of enhancers by
athletes is similar to the use of beta-blockers by classical musicians in that both kinds of
drugs lead to better entertainment.
According to this argument, enhancers promote an
artistic service to the community, , and not merely a narrowly individual good. However,
this does not seem to be the best way of understanding performance enhancement. Social
goods do not seem to figure much at all in the athletes’ reasons for doping: they are more
interested in achieving wealth or “hero status”
. In addition, the public seems to care
more about relative performance than about absolute performance; we still celebrate
winners even when records are not broken, and we enjoy youth and college leagues as
much as professional leagues, even though the absolute performance may often be lower.
Finally, the emphasis of sports-governing bodies on fairness
in regulating doping use
suggests that performance-enhancing drugs are viewed primarily as promoting narrowly
individual goods.
A contrasting example lies in cognitive enhancement. In the literature on this
education is often seen as the touchstone of a morally acceptable cognitive
enhancement. However, if we focus on college and graduate school education, we see how
cognitive enhancement inserts itself at the very heart of status hierarchies. This is why
third-level education is ethically ambiguous in a way that shows the limits of distributive
Much academic education (consider law, medicine, psychology, or engineering) is
directed toward entry into a profession. In fact, academia is often seen as an arena where
rival professions carry out proxy conflicts over who can claim “expertise.”
The close link
between academia and high-status professions is one of the main reasons why educational
attainment is so strongly positively correlated with life outcomes, whether one measures
that according to subjective well-being, self-esteem, or mental health,
or even chance of
disease, and mortality from all causes.
Many parents today recognize that education is a positional good. It is well
documented how certain parents are more actively involved so that their children will
gain access to status-enhancing educational institutions.
The most common
motivations cited are concern for the child’s future “well-being” and “success”, where the
latter specifically means success in the competition for status.
Moreover, the scarcer
education is and the fewer highly educated people there are, the more higher education
contributes more to subjective well-being.
Education, especially at a college level and beyond, sits uneasily on the dominance-
prestige divide. The competence it engenders can lead to better services being rendered
to the community, in which case the society as a whole benefits. However, education can
also be pursued for the sake of enjoying the privileges and benefits associated with status.
If the latter are not subordinated to service, then the privileges become means to allow
one’s individual preferences to weigh more strongly in the community: this is a subtle
form of dominance.
This dual nature of education is sometimes overlooked in the cognitive
enhancement literature, but it is not new. In ancient Greece, when systematic education
was still a relatively new development in human history, sophists and philosophers alike
were viewed with suspicion. Thus Isocrates (436-338 BC) was charged with “corrupting
the youth”: endowing them with rhetorical skill to gain an unfair advantage over peers
during court trials or debates over policy. Socrates, of course, was charged and sentenced
to death over the same “crime”; education, and the rhetorical and argumentative
supremacy it afforded, was viewed with suspicion. Today, scientific experts and highly
educated liberal elites are viewed with suspicion and distrust, and this distrust can be
interpreted as reflecting a moral uncertainty: will the powerful cognitive enhancement
that higher education represents be used for the benefit of the community, or to promote
patterns of dominance?
The fine line between dominance and prestige, and between privilege and service
that is strongly apparent in higher education, means that this form of cognitive
enhancement is both an individual good as well as a social good. This makes it difficult to
regulate the dangers of perverse competition through the conceptual framework of public
policy and distributive justice. If we follow the latter, then tertiary education is
conceptualized in terms of equality of opportunity. The problem is not that this is wrong,
but that it is problematically incomplete: the main question is not who gets the powerful
cognitive enhancement, but whether those who benefit from it use it for service or for
dominance. Enhancement through tertiary education is not merely an individual good
but also a social good.
This is why professional ethics offers a better model for thinking about how
cognitive enhancements should be regulated, where individual interests and community
interests are so strongly entangled. Associations of physicians, lawyers, or psychologists
do not regulate the conduct of their members in the way the International Cycling Union
regulates cyclists in the Tour de France. There is, in general, considerably more trust in
practicing professionals, not only from governing bodies, but also from the clients and
customers of the professionals. Moreover, attempts at coercing service-oriented attitudes
from individual members, whether through nudges or punishment, are often self-
This is why the self-regulation of professions is typically formulated more in
terms of ethics rather than policy oriented towards justice: having an ethics oriented
towards an ideal of service is, according to some sociologists, a defining characteristic of
what professionalism means.
Inequality is less of pressing issue: if a professional
decides to undergo additional cognitive enhancement, they may indeed accrue further
social status and privilege (as with the specialist physician who undergoes yet further
specialization), but the expectation is that this increased competence will be put at the
service of the community and that all will benefit.
In sum, it should be acknowledged that some enhancements predominantly entail
individual privilege: when this is the case (e.g. performance enhancing drugs), then the
principle of distributive justice is applicable. However, important classes of enhancement
such as cognitive enhancement, are not merely individual goods but also social goods.
They involve both prosocial responsibilities as well as privileges. For such types of
enhancement, a redistribution according to fairness principles may not prevent perverse
competition from happening anyway. Instead, the appropriate response lies in
strengthening the ethics of those undergoing enhancement. This is the basic idea
underlying the service view on enhancement.
5. The Service View of Enhancement
Let me recap the argument so far. Recent scientific developments in cultural evolutionary
theory suggest a group-centered view of human evolution where the interests of the
individual and community are intertwined, especially visible in how communities are
structured into status hierarchies which benefit both individuals and the community.
Decisions to enhance are strongly influenced by status hierarchies and can lead to
perverse competitions for dominance. This view casts doubt on the evolutionary rationale
for the libertarian idea, namely that individuals need enhancement due to their deeply
maladaptive evolved traits: the apparent mismatch may simply reflect their inability to
adapt to social-cultural environments, and the fault may lie in wayward status
hierarchies. It also casts doubt on the main libertarian idea that, unless direct harm is
threatened, individuals should be left unperturbed to pursue their wellbeing as they see
fit, and if that includes enhancing their capacities, then that should be endorsed.
We cannot enhance our way out of perverse status competition. Perhaps school
bullies can be pharmaceutically enhanced to stop bullying short children; however, the
proper application of such moral enhancement presupposes that there are parents with a
prior understanding of what is ethically desirable is needed. However, on a societal scale,
there are no such "parents", at least if one holds to libertarian view. A social liberal view
may seem more promising, by means of the principle of distributive justice. However, the
principle of justice is only applicable to individual goods – when the goods are social in
nature, then fair distributions among individuals can no longer be the guiding principle.
Given how individuals are embedded in social networks characterized by status
hierarchies, the proposal is that the real question lies not in how to maintain individual
autonomy (either through negative liberty, no harm, or distributive justice), but rather on
how to act in a way that benefits the community. To address this question, we might
consider the service view of enhancement: since enhancements are tools to increase the
competence and status of the individual, they should be judged according to how they
allow for a service to the community and according to how they contribute to or detract
from the ethos of service.
The service view provides a response to the problem of perverse status
competition, because, as long as an ethos of service is maintained, status competition
need not erode trust between individuals in a community. There can even be significant
inequality, but when high-status persons act for the good of the community rather than
for a more narrowly selfish good, then interpersonal trust can remain justified. One
person’s success does not come at the cost of another’s defeat; on the contrary, if they are
both part of the same community, the latter can benefit indirectly from the success of the
In what way is the service view an alternative to liberal views? First it should be
emphasized that the service view does not involve a jettisoning of the principle of
autonomy: there is still a meaningful distinction to be made between making one’s own
decisions and slavishly following what others say, do, or value. The service view is not an
illiberal view. However, it is also not a liberal view. It does not endorse the dichotomy
between private and public spheres:
the ethos of service, as the set of prestige-for-service
social norms, is situated in between the private and the public spheres. Neither are
individuals conceptualized as self-determining agents: they are members of a community,
and their ends may be significantly determined by the community they inhabit.
Is the service view a form of communitarianism? Communitarianism is under-
stood in many different ways, and a full account is not possible here. Howeverif
communitarianism implies that cultural traditions have intrinsic value,
then the service
view is not a form of communitarianism. Tradition is of value insofar it possesses time-
tested norms which may promote an ethos of service. However, tradition does not possess
an intrinsic value that can take precedence over the needs of service. Another way of
understanding the distinction is that the ethos of service defines a community through
shared future rather than through a shared cultural ancestry.
A second position often associated with communitarianism is that the community
is considered as a subject with its own rights.
By contrast, in the service view, the only
real agency involved here is that of individuals: the ethos of service is a guiding principle
for individual decision-making, and ultimately directed towards individual well-being.
Paradoxically, the service view can be thought of a refinement of the fundamental values
of liberalism but refined to such a point that the principle of autonomy ceases to be
useful. Service is a principle for individuals making decisions about their life course,
where decisions are made on the basis of how one can contribute to the community.
Service is not antithetical to individual well-being: in reality, one achieves well-being
precisely by being meaningful to other people. If well-being is the satisfaction of interests
or preferences, then the principle of service allows one to discern what interests or
preferences are worth satisfying.
Enhancement Ethics and Science. How should one, after all this, understand
the role that cultural evolutionary theory has played in the argument presented here? My
suggestion is that evolutionary science should not be thought of as preempting ethical
reflection, but rather as presenting the ethicist with a wealth of information about the
human condition, which can inform ethical reasoning. Cultural evolutionary theory
allows the ethicists a better and more detailed understanding of some of the more subtle
consequences of decisions to enhance, based on facts of our status-oriented moral
psychology. Humans face anxieties, worries, impostor syndromes, insecurities,
competitive urges and so on all challenges that seem crucial concerning decisions to
By arguing that a properly updated evolutionary perspective does not support
liberal views, I did not argue that they are wrong or false. Rather, the implication is that
liberal views, whether in social liberal or libertarian guise, just do not seem to offer
meaningful guidance for the challenges that are inherent to being an individual who is
also a member of a community. The challenges of anxieties, insecurities, competitiveness,
and so on, would simply be categorized as obstacles to autonomy that the rational
individual should ignore or avoid as much as possible.
The option is still open for the liberal to simply repudiate our evolved moral
psychology, and claim it needs to be overcome in some wholesale way. For instance,
liberal could still maintain that the response to the challenging psychological realities lies
in more enhancement even if that ultimately will lead us away from liberalism and
towards transhumanism, as explicitly endorsed by Yuval Harari.
However, such a
strategy would only serve to underline the main thesis of this article, namely, that the
evolutionary perspective on enhancement does not support a liberal view (and not an
illiberal view for that matter).
Interestingly, common sense (in the form of “public opinion”) seems to follow what
one would expect given cultural evolutionary theory. In a recent survey study, many
participants judged the ethical acceptability of enhancement to depend on features in the
social environment. For instance, if enhancement is used to intensify competition, it is
more likely to face disapproval, but if an enhancement technology is commonly used by
peers or approved of by authority figures, then it is more likely to be positively evaluated.
Enhancement use by professionals such as surgeons or pilots meets more approval than
does such use by students. Elsewhere I argue in more detail that these judgments are what
one would expect if one takes our status-related motivations into consideration, and given
that our judgments are guided by an ethos of service.
Thus the service view, far from
repudiating our evolved moral psychology as “irrational,shows how there is an the
ethical logic inherent to the service-for-prestige norms that have evolved throughout
human history.
Enthusiasm or Caution? Proponents of liberal views of enhancement have
often also been promotors of enhancement as such.
Hence, in targeting liberal views,
the service view will inevitably give the impression of being cautionary. The cautionary
argument from service emphasizes that important classes of enhancement, including
cognitive enhancements, can be used to increase dominance, and even if the enhancement
does not cause any direct harm to others, over a longer period it can erode the ethos of
service and lead to distrust. This cautionary argument does not underwrite an argument
for prohibition, but for (moral) education, where service-for-prestige norms are
communicated as ethical norms. Here the closest parallel lies with how professional
bodies are supposed to self-regulate: through education and an adherence to a code of
ethics, trust between professionals (and their clients) is maintained.
Nonetheless, just as a liberal view can recommend caution if an enhancement
threatens to erode individual autonomy,
the service view could also support
enthusiasm. If a proposed enhancement allows an individual to provide a better service
to others, and does not lead that person to assume a position of dominance over others,
then it is ethically commendable. Safety considerations are relevant, of course, but even a
small amount of damage to the user may be outweighed by service. For instance, even if
using amphetamines causes slight neuronal damage to pilots or surgeons, it could be
ethically justified if it allows them to suppress sleep and to better serve their passengers
or patients can thus be ethically approved. Obviously, there is a balance to be struck:
taking a lethal enhancement to provide one act of service does not make for better service
over a longer time-scale. In this way, the service view on enhancement can ground an
alternative way of ethically deliberating about enhancement: one that is in principle
neither more enthusiastic or cautionary than the liberal view, but more grounded in what
we know about both how humans originated, and about humans' actual desires for and
experiences of enhancement.
6. Conclusion
How autonomous are our Millian experiments of living? To what extent are these
driven by the community we inhabit, with its norms, values, and patterns of behavior? In
this article, I drew on cultural evolutionary theory to show how the Darwinian
competition for status has shaped our moral psychology, and a fortiori our decisions to
enhance. The threat of perverse competition not only undermines evolutionary
arguments for the liberal view on enhancement, but the very appropriateness of the liberal
view. The principles of no-harm and of distributive justice are of limited help when faced
with types of enhancement like cognitive enhancement which are positional social goods,
and where the ethics (e.g., intention, orientation towards service) of the enhancer
determines the ethics of the enhancement. By contrast, the service view on enhancement
explicitly acknowledges the challenges of living in community, and has more in common
with professional ethics rather than liberal political philosophy. Individuals in the West
have been strongly influenced by the liberal focus on autonomy, but given our evolved
moral psychology and underreported but clearly documented competition for status in
liberal societies, the service view on enhancement appears to be an attractive alternative
to the dominant liberal view.

Except if, through the vagaries of fashion or the contingency of cultural evolution, the useless
enhancement becomes a status signal. The custom of foot binding seems to be an example of this: foot
binding is an “enhancement” in the sense of keeping adult foot size abnormally small, and despite coming
at a terrible price, it nonetheless spread in historical Chinese societies in large part because it had become
a status signal.

... Thus, the learner is conceptualized as an agent in this limited respect. Nonetheless, by explaining the adaptiveness of human behavior through natural selection (and selection by the environment), cultural evolutionary theory serves to undermine the idea that humans are autonomous, self-determining agents (this relation between cultural evolutionary theory and autonomy is explored further in Desmond, 2021). 470 H. Desmond How does this contrast between agential and selectionist explanations play out more generally? ...
Human culture changes over time and varies across space. Two main approaches to study cultural evolution have developed in the last fifty years: human behavioural ecology and a suite of perspectives centred on the role of cultural transmission. The latter are often confusingly referred to with the name of the phenomenon they are trying to explain, ‘cultural evolution’. We argue that this is unhelpful and is generating confusion, including the claim that human behavioural ecology disregards cultural evolution. The aim of behavioural ecology is to explain human behaviours, and the vast majority of them are at least to some extent cultural. In addition, culture forms part of the ecology that determines the costs and benefits associated with adopting a behaviour. Thus, human behavioural ecologists have studied cultural evolution from the very beginning, even though they have not focussed on social learning. We explore three examples in detail: kinship systems, religious institutions, and witchcraft belief. We then use the framework offered by Tinbergen’s [1963, Z Tierpsychol, 20(4), 410-433] four evolutionary questions about behaviour to explain how human behavioural ecology and cultural transmission approaches can fruitfully coexist and complement each other. Moreover, we discuss several difficulties with cultural transmission approaches and highlight how the human behavioural ecological view of cultural evolution sometimes diverges from them. We conclude by suggesting that the field can move forward and achieve greater synthesis by exploring how selective processes acting on biological fitness differ from those acting on cultural fitness – and how the two might interact in the cultural evolution of human behaviours.

... Such examples are not marginal considerations for the ethics of enhancement. Elsewhere I have worked to show how social status infiltrate many of our decisions-especially decisions to enhance-and how an ethics of enhancement should reflect this (Desmond 2020(Desmond , 2021. The examples also point to the limits of an individual-focused ethics, since our ideas about what will bring us "welfare" or "benefit" is inextricably bound up with the evaluative judgments present in families, communities, or even online environments such as social media (for the latter, see Desmond 2022). ...
... However, whether such diminishment would occur with much frequency is doubtful, given the close link between cognitive capacity and status gains and human psychology's orientation toward status. e role social status plays in decisions to enhance is documented in more detail in other work (Desmond 2021b). However, for purposes here, we can conclude that techno-libertarian success does not re ect how individuals are entangled with their social environments. ...

In one vision of human success, future human evolution lies in enhancing our bodies and especially our minds, in order to achieve new levels of cooperation, morality, and wellbeing. In unadulterated form, this vision combines a pessimism in the human evolutionary heritage with an optimism in what technological enhancement could offer. I point to a crucial blind spot: the role the social and cultural environment has played and continues to play in human evolution. In particular, I emphasize how enhancement technologies are co-opted in the competition for social status. When this is taken into consideration, the vision of techno-libertarian success seems both less appealing and less plausible. In closing I identify two desiderata for the concept of human success in the future.

According as the principle of natural selection is generalized to explain (adaptive) patterns of human behavior, the exact nature of the selective environment becomes less clear. While the environment and the individual are relatively separable in the non-human biological context, they are highly entangled in the context of moral, social, and institutional evolution. This chapter draws attention to the problem of generalizing the selective environment, and argues that it is ontologically disunified and definable only through its explanatory function. What unifies the selective environment is that it explains adaptation in a non-agential way, by screening off various forms of agency, whether divine, organismic, or human. This explanatory function of the selective environment helps avoid some sources of confusion when the theory of natural selection is applied to the humanities and social sciences.

The dominant view today on evolutionary progress is that it has been thoroughly debunked. Even value-neutral progress concepts are seen to lack important theoretical underpinnings: (1) natural selection provides no rationale for progress, and (2) natural selection need not even be invoked to explain large-scale evolutionary trends. In this paper I challenge this view by analysing how natural selection acts in heterogeneous environments. This not only undermines key debunking arguments, but also provides a selectionist rationale for a pattern of “evolutionary unfolding”, where life radiates across an increased range of exploitation of environmental heterogeneity.

Philosophers of science and meta-scientists alike now typically model scientists’ behavior as driven by credit maximization. In this paper I argue that this modeling assumption cannot account for how scientists have a default level of trust in each other’s assertions. The normative implication of this is that science policy should not only focus on incentive reform.

The germ theory of disease and the attendant public health initiatives, including sanitation, vaccination, and antibiotic treatment, led to dramatic increases in global life expectancy. As the prevalence of infectious disease declines, mental disorders are emerging as major contributors to the global burden of disease. Scientists understand little about the etiology of mental disorders, however, and many of the most popular psychopharmacological treatments, such as antidepressants and antipsychotics, have only moderate‐to‐weak efficacy in treating symptoms and fail to target biological systems that correspond to discrete psychiatric syndromes. Consequently, despite dramatic increases in the treatment of some mental disorders, there has been no decrease in the prevalence of most mental disorders since accurate record keeping began. Many researchers and theorists are therefore endeavoring to rethink psychiatry from the ground‐up. Anthropology, especially biological anthropology, can offer critical theoretical and empirical insights to combat mental illness globally. Biological anthropologists are unique in that we take a panhuman approach to human health and behavior and are trained to address each of Tinbergen's four levels of analysis as well as culture. The field is thus exceptionally well‐situated to help resolve the mysteries of mental illness by integrating biological, evolutionary, and sociocultural perspectives.

What if there were a pill for love? Or an anti-love drug, designed to help us break up? This controversial and timely new book argues that recent medical advances have brought chemical control of our romantic lives well within our grasp. Substances affecting love and relationships, whether prescribed by doctors or even illicitly administered, are not some far-off speculation - indeed our most intimate connections are already being influenced by pills we take for other purposes, such as antidepressants. Treatments involving certain psychoactive substances, including MDMA-the active ingredient in Ecstasy-might soon exist to encourage feelings of love and help ordinary couples work through relationship difficulties. Others may ease a breakup or soothe feelings of rejection. Such substances could have transformative implications for how we think about and experience love. This brilliant intervention into the debate builds a case for conducting further research into "love drugs" and "anti-love drugs" and explores their ethical implications for individuals and society. Rich in anecdotal evidence and case-studies, the book offers a highly readable insight into a cutting-edge field of medical research that could have profound effects on us all. Will relationships be the same in the future? Will we still marry? It may be up to you to decide whether you want a chemical romance.

Some of the most significant policy responses to cases of fraudulent and questionable conduct by scientists have been to strengthen professionalism among scientists, whether by codes of conduct, integrity boards, or mandatory research integrity training programs. Yet there has been little systematic discussion about what professionalism in scientific research should mean. In this paper I draw on the sociology of the professions and on data comparing codes of conduct in science to those in the professions, in order to examine what precisely the model of professionalism implies for scientific research. I argue that professionalism, more than any other single organizational logic, is appropriate for scientific research, and that codes of conduct for scientists should strengthen statements concerning scientific autonomy and competence, as well as the scientific service ideal.
People vary widely in their acceptance of the use of pharmacological cognitive enhancement (CE). We tested the hypothesis that the acceptability of CE is malleable, by varying the context in which CE use takes place, by framing the use of CE with positive and negative metaphors, and by distinguishing between self and other CE use. 2,519 US-based participants completed 2 surveys using Amazon’s Mechanical Turk. First, participants responded to vignettes describing a fictional character, which varied by framing metaphor (Pandora’s box that releases brain performance vs. key that unlocks brain potential), role/setting (student/educational vs. employee/professional), and activity type (blue vs. white collar). Second, participants viewed personalized vignettes describing their own situations. Across both surveys, participants generally found CE use more acceptable for employees than students, while the effects of framing metaphors were unreliable and smaller than previously reported. People were more accepting of CE use by others than by themselves. Participants also found CE use more acceptable if more peers used CE, the environment was less competitive, and authority figures encouraged CE use. Our findings suggest that opinions about CE are indeed malleable, and concerns that peer pressure, the influence of authority figures, and competition might affect CE use are not unfounded.
