}}`````` **Enhancement arms race** describes a situation in which the benefit of an enhancement depends on having it when others do not, so that each person's rational decision to adopt it removes the advantage while leaving everyone with the costs. The argument is the strongest objection to enhancement that does not depend on any claim about human nature, dignity, or the value of the given. It concedes that the technology works, that people choose it freely, and that each choice is individually sensible — and shows that the outcome can still be worse for everyone.**Enhancement arms race** describes a situation in which the benefit of an enhancement depends on having it when others do not, so that each person's rational decision to adopt it removes the advantage while leaving everyone with the costs. The argument is the strongest objection to enhancement that does not depend on any claim about human nature, dignity, or the value of the given. It grants that the technology works, that people choose it freely, and that each choice is individually sensible, and it shows that the outcome can still be worse for everyone. ## Positional and absolute goods## Positional and absolute goods The distinction comes from Fred Hirsch, who observed that some goods are valuable in themselves and others only in relation to what others have.[^hirsch1976] Clean water is absolute: everyone having it is better than some people having it. A front-row seat is positional: its value consists in others not having it. Robert Frank extended the analysis to biological competition, noting that traits selected for relative advantage — antler size is his standing example — impose costs on every member of the population without improving any individual's rank.[^frank2011]The distinction comes from Fred Hirsch, who observed that some goods are valuable in themselves and others only in relation to what others have.[^hirsch1976] Clean water is absolute: everyone having it is better than some people having it.

Universal adoption makes everyone better off, and for infectious disease the externality runs positive — one person's immunity protects others. Nobody argues for restricting these, which is why the therapy side of [[bioethics-of-enhancement]] is comparatively uncontested.**Absolute.** Resistance to infection, repair of damaged tissue, freedom from pain.

It is positional in selection contexts — a fixed number of medical school places will be filled whatever the applicants' capabilities. It is absolute wherever thinking produces something others can use, and the historical spillovers from literacy, numeracy, and public education were enormous.

If nobody enhances, the ranking is unchanged and nobody bears the cost. If everybody enhances, the ranking is unchanged and everybody bears the cost. If one enhances and others do not, that one gains. Defection dominates, and the equilibrium is universal adoption with no benefit.For a purely positional enhancement with real costs, the payoff matrix is a prisoner's dilemma. If nobody enhances, the ranking is unchanged and nobody bears the cost. If everybody enhances, the ranking is unchanged and everybody bears the cost. If one enhances and others do not, that one gains. Defection dominates, and the equilibrium is universal adoption with no benefit. The mechanism does not require anyone to be forced. It is the reason "voluntary" is a weak defence of enhancement in competitive settings: the availability of an option changes the situation of people who decline it, a form of pressure that liberal frameworks based on individual consent handle poorly. It also cuts against the standard fairness objection developed in [[access-and-inequality]] — the arms-race problem is worst precisely when access is *equal*, because then everyone adopts.The mechanism does not require anyone to be forced.

Equal access to a positional enhancement produces universal cost with no advantage. Policies that fix the first can make the second worse, so "just make it available to everyone" does not work as a general solution. ## The worked example: sport## The worked example: sport Athletic competition is a pure positional contest with an explicit ranking, which is why it is the only domain where the dynamic has been observed at scale and the only one with a mature regulatory response. The anti-doping regime described in [[enhancement-in-sport]] exists because athletes in several sports demonstrated in the 1970s and 1980s that in the absence of enforcement, the equilibrium is universal use of drugs with serious health costs and unchanged relative standings.Athletic competition is a pure positional contest with an explicit ranking. That is why it is the only domain where the dynamic has been observed at scale and the only one with a mature regulatory response. The anti-doping regime described in [[enhancement-in-sport]] exists because athletes in several sports demonstrated in the 1970s and 1980s that in the absence of enforcement, the equilibrium is universal use of drugs with serious health costs and unchanged relative standings. The regime's rationale is explicitly collective: it is not that doping is unnatural but that a testable prohibition is the only way to reach the outcome most athletes say they prefer. Whether it works is disputed — detection lags the pharmacology, and [[gene-doping]] would be harder to detect than any small molecule, though no confirmed case has been documented. The Enhanced Games, an event announced in 2023 and scheduled to run in 2026, proposes the opposite equilibrium: permit everything, disclose everything, and treat the resulting performances as a separate category. It is the first serious attempt to test whether an unregulated equilibrium is stable, and the medical objections are substantial.The regime's rationale is explicitly collective.

Amphetamines have been issued to combat pilots for decades to sustain performance on long missions, a practice that surfaced publicly in the litigation following a 2002 friendly-fire incident in Afghanistan. US defence research agencies have funded programmes on sustained performance without sleep, on physical endurance, and on non-surgical neural interfaces intended for able-bodied operators rather than patients.Militaries face the arms-race structure directly and have no international body corresponding to the anti-doping agency.

US defence research agencies have funded programmes on sustained performance without sleep, on physical endurance, and on non-surgical neural interfaces intended for able-bodied operators rather than patients. Claims about foreign programmes have been used to justify domestic ones. A senior US intelligence official asserted in a 2020 newspaper op-ed that China had conducted human testing on military personnel with the aim of producing biologically enhanced soldiers; no supporting evidence was published then or since. The pattern is familiar from earlier arms races: unverifiable claims about an adversary's capability are themselves an input to the race, and are hard to distinguish from advocacy.Claims about foreign programmes have been used to justify domestic ones.

The military domain is where the tools discussed in [[non-invasive-neuromodulation]], [[exoskeleton]], [[myostatin-inhibition]], and [[sleep-reduction]] research are most likely to be adopted first, because the institution can order adoption and internalise the costs. It is also where the liberty framing of [[morphological-freedom]] has least purchase, since the person modified does not choose.The military domain is where the tools discussed in [[non-invasive-neuromodulation]], [[exoskeleton]], [[myostatin-inhibition]], and [[sleep-reduction]] research are most likely to be adopted first, because the institution can order adoption and internalise the costs.

Surveys of stimulant use among students and academics — including an informal poll of readers conducted by a scientific journal in 2008 that found roughly a fifth of respondents reporting non-medical use for cognitive purposes — indicate that people believe otherwise.[^maher2008] The evidence reviewed in [[nootropics]] does not support them. Prescription stimulants and modafinil produce reliable effects on wakefulness and small, inconsistent effects on cognition in rested healthy adults, with some studies finding that they increase effort and confidence more than accuracy. An arms race over an ineffective enhancement wastes resources without changing outcomes, which is a real cost but a different problem.Surveys of stimulant use among students and academics indicate that people believe otherwise; one, an informal poll of readers conducted by a scientific journal in 2008, found roughly a fifth of respondents reporting non-medical use for cognitive purposes.[^maher2008] The evidence reviewed in [[nootropics]] does not support them.

The genuine civilian enhancement arms race is educational and financial: tutoring, test preparation, and school selection, which have measurable effects, are purchased overwhelmingly by the wealthy, and are almost entirely unregulated.

Biological enhancement is discussed as though it would introduce a dynamic that has in fact been operating for a century. The nearest biological candidate is reproductive rather than pharmacological. [[polygenic-embryo-screening]] is purchasable, unregulated in most jurisdictions, and confers whatever advantage it confers before the child can consent — the structure of a positional race with the participants selected in advance, which is the version the ethics literature is least equipped to address.The nearest biological candidate is reproductive rather than pharmacological.

Weight classes and paralympic classification do this in sport; admissions lotteries above a threshold do it in education. Which of these applies to any given enhancement depends on the positional-versus-absolute question, and that question has not been answered empirically for a single candidate technology — including the one, [[genetic-enhancement-of-intelligence]], around which most of the argument has been conducted.Which of these applies to any given enhancement depends on the positional-versus-absolute question, and that question has not been answered empirically for a single candidate technology.
