Evolutionary psychology controversy
Encyclopedia
From its beginning, evolutionary psychology
(EP) has generated substantial controversy and criticism. Criticisms include 1) disputes about the testability of evolutionary hypotheses, 2) alternatives to some of the cognitive assumptions (such as massive modularity) frequently employed in evolutionary psychology, 3) vagueness stemming from evolutionary assumptions (e.g. uncertainty about the environment of evolutionary adaptation, EEA), 4) differing stress on the importance of non-genetic and non-adaptive explanations, as well as 5) political and ethical issues.
Evolutionary psychologists respond by arguing that many of these criticisms are straw men, are based on a incorrect nature vs. nurture dichotomy, or are based on a misunderstandings of the discipline.
The history of the debate from the critics' perspective is detailed by Gannon (2002). Critics of EP include the philosophers of science David Buller author of Adapting Minds, Robert C. Richardson author of Evolutionary Psychology as Maladapted Psychology, and Brendan Wallace, author of Getting Darwin Wrong: Why Evolutionary Psychology Won't Work. Other critics include Neurobiologists like Steven Rose
who edited "Alas, Poor Darwin: Arguments against Evolutionary Psychology", and biological anthropologists like Jonathan Marks and social anthropologists like Tim Ingold
and Marshall Sahlins
.
Critics of EP have argued that evolutionary psychology is based on misconceptions of biological and evolutionary theory.
theory used in evolutionary psychology (massive modularity). Critics, including some psychologists using other evolutionary frameworks, argue in favor of other theories.
s.
Part of the critique of the scientific base of evolutionary psychology includes a critique of the concept of the environment of evolutionary adaptation (EEA). EP often assumes that human evolution occurred in a uniform environment, and critics suggest that we know so little about the environment (or probably multiple environments) in which homo sapiens evolved, that explaining specific traits as an adaption to that environment becomes highly speculative.
Evolutionary psychologists John Toby and Leda Cosmides state that research is confined to certainties about the past, such as pregnancies only occurring in women, and that humans lived in groups. They argue that there are many environmental features that are known regarding our species' evolutionary history. They argue that our hunter-gatherer
ancestors dealt with predators and prey, food acquisition
and sharing, mate choice, child rearing, interpersonal aggression, interpersonal assistance, diseases and a host of other fairly predictable challenges that constituted significant selection pressures. Knowledge also include things such as nomadic, kin-based lifestyle in small groups, long life for mammals, low fertility for mammals, long female pregnancy and lactation, cooperative hunting and aggression, tool use, and sexual division of labor.
Critics argue that many hypotheses put forward to explain the adaptive nature of human behavioural traits are "just-so stories"; neat adaptive explanations for the evolution of given traits that do not rest on any evidence beyond their own internal logic. They allege that evolutionary psychology can predict many, or even all, behaviours for a given situation, including contradictory ones. Therefore many human behaviours will always fit some hypotheses. Noam Chomsky
argued:
Leda Cosmides
argued in an interview:
A 2010 review article by evolutionary psychologists describes how an evolutionary theory may be empirically tested. An hypothesis is made about the evolutionary cause of a psychological phenomenon or phenomena. Then the researcher makes predictions that can be tested. This involves predicting that the evolutionary cause will have caused other effects than the ones already discovered and known. Then these predictions are tested. The authors argue numerous evolutionary theories have been tested in this way and confirmed or falsified. Buller (2005) makes the point that the entire field of evolutionary psychology is never confirmed or falsified; only specific hypotheses, motivated by the general assumptions of evolutionary psychology, are testable. Accordingly he views evolutionary psychology as a paradigm
rather than a theory, and attributes this view to prominent evolutionary psychologists including Cosmides, Tooby, Buss, and Pinker.
In his review article
Discovery and Confirmation in Evolutionary Psychology (in The Oxford Handbook of Philosophy of Psychology) Edouard Machery concludes:
's book on evolutionary psychology (The Blank Slate
), Louis Menand wrote: "In general, the views that Pinker derives from 'the new sciences of human nature' are mainstream Clinton-era views: incarceration is regrettable but necessary; sexism is unacceptable, but men and women will always have different attitudes toward sex; dialogue is preferable to threats of force in defusing ethnic and nationalist conflicts; most group stereotypes are roughly correct, but we should never judge an individual by group stereotypes; rectitude is all very well, but 'noble guys tend to finish last'; and so on.".
However, evolutionary psychologists point out that their research actually focuses on commonalities between people of different cultures to help to identify "human psychological nature" and cultural universals. It is not a focus on local behavioral variation (which may sometimes be considered ethnocentric) that interests evolutionary psychologists; rather their focus is to find underlying psychological commonalities between people from various cultures.
Evolutionary psychology is in part based on the theory that our psychology
is fundamentally based on biology
, the composition of our brains. Some see this as a form of reductionism whereby the nature of complex things can be understood in terms of simpler or more fundamental things (i.e. reduced
).
Such critics argue that a reductionist analysis of the relationship between genes and behaviour results in a flawed research program and a restricted interpretation of the evidence, creating problems for the creation of models attempting to explain behaviour. Lewontin, Rose & Kamin instead advocate a dialectical interpretation of behaviour in which "it is not just that wholes are more than the sum of their parts, it is that parts become qualitatively new by being parts of the whole." They argue that reductionist explanations such as the hierarchical reductionism proposed by Richard Dawkins
will cause the researcher to miss dialectical ones.
Evolutionary psychologists Workman and Reader reply that while reductionism may be a "dirty word" to some it is actually an important scientific principle. They argue it is at the root of discoveries such as the world being made up of atoms and complex life being the result of evolution. At the same time they emphasize that it is important to look at all "levels" of explanations, e.g. both psychologists looking at environmental causes of depression and neuroscientists looking the brain contribute to different aspects of our knowledge of depression. Workman and Reader also deny the accusation of genetic determinism, asserting that genes usually do not cause behaviors absolutely but predispose to certain behaviors that are affected by factors such as culture and an individual's life history.
Critics assert that evolutionary psychology has trouble developing research that can distinguish between environmental and cultural explanation and adaptive evolutionary explanations. Some studies have been criticized for their tendency to attribute to evolutionary processes elements of human cognition that may be attributable to social processes (e.g. preference for particular physical features in mates), cultural artifacts (e.g. patriarchy and the roles of women in society), or dialectical considerations (e.g. behaviours in which biology interacts with society, as when a biologically determined skin colour determines how one is treated). Evolutionary psychologists are frequently criticized for ignoring the vast bodies of literature in psychology, philosophy, politics and social studies. Both sides of the debate stress that statements such as "biology vs. environment" and "genes vs. culture" amount to false dichotomies, and outspoken critics of sociobiology
such as Richard Lewontin
, Steven Rose and Leon Kamin
helped to popularise a "dialectical" approach to questions of human behaviour, where biology and environment interact in complex ways to produce what we see.
Evolutionary psychologists respond that their discipline is not primarily concerned with explaining the behavior of specific individuals, but rather broad categories of human behaviors across societies and cultures. It is the search for species-wide psychological adaptations (or "human nature") that distinguishes evolutionary psychology from purely cultural or social explanations. These psychological adaptations include cognitive decision rules that respond to different environmental, cultural, and social circumstances in ways that are (on average) adaptive.
Evolutionary psychologists Confer et al. argue the evolutionary psychology fully accept nature-nurture interactionism and that it possible to test the theories in order to distinguish between different explanations.
refers to random effects resulting from chance variation in the genes, environment, or development. Evolutionary by-products are traits that were not specially designed for an adaptive function, although they may also be species-typical and may also confer benefits on the organism. A "spandrel
" is a term coined by Gould
and Lewontin (1979a) for traits which confer no adaptive advantage to an organism, but are 'carried along' by an adaptive trait. Gould advocates the hypothesis that cognition in humans came about as a spandrel: "Natural selection made the human brain big, but most of our mental properties and potentials may be spandrels - that is, nonadaptive side consequences of building a device with such structural complexity".
Once a trait acquired by some other mechanism confers an adaptive advantage, as evolutionary psychologists argue that many of our "mental properties and potentials" do, it may be open to further selection as an "exaptation
". Critics allege that the adaptive (and exaptive) significance of mental traits studied by evolutionary psychologists has not been shown, and that selection has not necessarily guided the appearance of such traits.
Evolutionary psychologists suggest that critics mischaracterize their field, and that their empirical research is designed to help identify which psychological traits are likely to adaptations, and which are not.
The disjunction problem occurs when a mechanism appears to respond to one thing (F), but is also correlated with another (G). Whenever F is present, G is also present, and the mechanism seems to respond to both F and G. The difficulty thus involves deciding whether to characterize the mechanism's adaptive function as being related to F, G, or both. “For example, a frogs pre-catching mechanism responds to flies, bees, food pellets, etc.; so is its adaptation attuned to flies, bees, fleebees, pellets, all of these, or just some?”
The grain problem refers to the challenge in knowing what kind of environmental ‘problem’ an adaptive mental mechanism might have solved. As summarized by Sterenly & Griffiths (1999): “What are the problems ‘out there’ in the environment? Is the problem of mate choice a single problem or a mosaic of many distinct problems? These problems might include: When should I be unfaithful to my usual partner? When should I desert my old partner? When should I help my sibs find a partner? When and how should I punish infidelity?” The grain problem therefore refers to the possibility that an adaptive problem may actually involve a set of nested ‘sub-problems’ “which may themselves relate to different input domains or situations. Franks states that "if both adaptive problems and adaptive solutions are indeterminate, what chance is there for evolutionary psychology?"
Franks also states that "The arguments in no sense count against a general evolutionary explanation of psychology." and that by relaxing assumptions the problems may be avoided, although this may reduce the ability to make detailed models.

Evolutionary psychologists have proposed explanations, such that there may be reproductive benefits for relatives or that they may be byproducts of adaptive behaviors that usually increase reproductive success but a review by Confer et al. states that they "remain at least somewhat inexplicable on the basis of current evolutionary psychological accounts"
. The implications are as broad and varied as the field of ethics itself.
view points.
Many critics have alleged that evolutionary psychology and sociobiology are nothing more than political justifications for the "status quo." Evolutionary psychologists have been accused of conflating "is" and "ought", and evolutionary psychology has been used to argue against social change (because the way things are now has been evolved and adapted), and to argue against social justice (e.g. the argument that the rich are only rich because they've inherited greater abilities, so programs to raise the standards of the poor are doomed to fail).
In rebuttal, Glenn Wilson
, a pioneer of EP, "promoting recognition of the true power and role of instincts is not the same as advocating the total abandonment of social restraint." Left-wing philosopher Peter Singer
in his book A Darwinian Left
has argued that the view of human nature provided by evolution is compatible with and should be incorporated into the ideological framework of the Left.
Evolutionary psychology critics have argued that researchers use their research to promote a right-wing agenda. Evolutionary psychologists conducted a 2007 study investigating the views of a sample of 168 United States PhD
psychology students. The authors concluded that those who self-identified as adaptationists were much less conservative than the general population average. They also found no differences compared to non-adaptationist students and found non-adaptationists to express a preference for less strict and quantitative scientific methodology than adaptationists.
The book The Blank Slate
by Steven Pinker responded to many of the moral and political criticisms. He also describes two logical fallacies. "The naturalistic fallacy
is the idea that what is found in nature is good. It was the basis for Social Darwinism, the belief that helping the poor and sick would get in the way of evolution, which depends on the survival of the fittest. Today, biologists denounce the Naturalistic Fallacy because they want to describe the natural world honestly, without people deriving morals about how we ought to behave -- as in: If birds and beasts engage in adultery, infanticide, cannibalism, it must be OK)."
"The moralistic fallacy
is that what is good is found in nature. It lies behind the bad science in nature-documentary voiceovers: lions are mercy-killers of the weak and sick, mice feel no pain when cats eat them, dung beetles recycle dung to benefit the ecosystem and so on. It also lies behind the romantic belief that humans cannot harbor desires to kill, rape, lie, or steal because that would be too depressing or reactionary."
Evolutionary psychology has been criticized by some feminists, such as Tang-Martinez, as justifying rape
. Evolutionary psychologists McKibbin et al. argue that this is a fallacy in the same way it would be a fallacy to accuse the scientists doing research on the causes of cancer
of justifying cancer. Instead, they argue that understanding the causes of rape may help create preventive measures.
For more discussion of these issues, see Confer, et al., (2010).

Environment of evolutionary adaptedness
One method employed by evolutionary psychologists is using knowledge of the environment of evolutionary adaptedness to generate hypotheses regarding possible psychological adaptations.Part of the critique of the scientific base of evolutionary psychology includes a critique of the concept of the environment of evolutionary adaptation (EEA). EP often assumes that human evolution occurred in a uniform environment, and critics suggest that we know so little about the environment (or probably multiple environments) in which homo sapiens evolved, that explaining specific traits as an adaption to that environment becomes highly speculative.

Knowledge also include things such as nomadic, kin-based lifestyle in small groups, long life for mammals, low fertility for mammals, long female pregnancy and lactation, cooperative hunting and aggression, tool use, and sexual division of labor.
Testability
A frequent critique of EP is that its hypotheses are difficult or impossible to adequately test, challenging its status as an empirical science. As an example, critics point out that many current traits likely evolved to serve different functions than they do now, confounding attempts to make backward inferences into history. Evolutionary psychologists acknowledge the difficulty of testing their hypotheses but assert it is nevertheless possible.Critics argue that many hypotheses put forward to explain the adaptive nature of human behavioural traits are "just-so stories"; neat adaptive explanations for the evolution of given traits that do not rest on any evidence beyond their own internal logic. They allege that evolutionary psychology can predict many, or even all, behaviours for a given situation, including contradictory ones. Therefore many human behaviours will always fit some hypotheses. Noam Chomsky

argued in an interview:
- "Those who have a professional knowledge of evolutionary biology know that it is not possible to cook up after the fact explanations of just any trait. There are important constraints on evolutionary explanation. More to the point, every decent evolutionary explanation has testable predictions about the design of the trait. For example, the hypothesis that pregnancy sickness is a byproduct of prenatal hormones predicts different patterns of food aversions than the hypothesis that it is an adaptation that evolved to protect the fetusFetusA fetus is a developing mammal or other viviparous vertebrate after the embryonic stage and before birth.In humans, the fetal stage of prenatal development starts at the beginning of the 11th week in gestational age, which is the 9th week after fertilization.-Etymology and spelling variations:The...

Evolutionary hypotheses – whether generated to discover a new trait or to explain one that is already known – carry predictions about the nature of that trait.

A 2010 review article by evolutionary psychologists describes how an evolutionary theory may be empirically tested. An hypothesis is made about the evolutionary cause of a psychological phenomenon or phenomena. Then the researcher makes predictions that can be tested. This involves predicting that the evolutionary cause will have caused other effects than the ones already discovered and known. Then these predictions are tested.

In his review article
Discovery and Confirmation in Evolutionary Psychology (in The Oxford Handbook of Philosophy of Psychology) Edouard Machery concludes:
- "Evolutionary psychology remains a very controversial approach in psychology, maybe because skeptics sometimes have little first-hand knowledge of this field, maybe because the research done by evolutionary psychologists is of uneven quality. However, there is little reason to endorse a principled skepticism toward evolutionary psychology: Although clearly fallible, the discovery heuristics and the strategies of confirmation used by evolutionary psychologists are on a firm grounding."
Ethnocentrism
One aspect of evolutionary psychology is finding traits that have been shown to be universal in humans. Many critics have pointed out that many traits considered universal at some stage or another by evolutionary psychologists and sociobiologists often turn out to be dependent on cultural and particular historical circumstances. Critics allege that evolutionary psychologists tend to assume that their own current cultural context represents a universal human nature; for example, in a review of Steven PinkerSteven Pinker

Such critics argue that a reductionist analysis of the relationship between genes and behaviour results in a flawed research program and a restricted interpretation of the evidence, creating problems for the creation of models attempting to explain behaviour.

At the same time they emphasize that it is important to look at all "levels" of explanations, e.g. both psychologists looking at environmental causes of depression and neuroscientists looking the brain contribute to different aspects of our knowledge of depression. Workman and Reader also deny the accusation of genetic determinism, asserting that genes usually do not cause behaviors absolutely but predispose to certain behaviors that are affected by factors such as culture and an individual's life history.
Adaptive explanations vs. environmental, cultural, social, and dialectical explanations
A common critique is that evolutionary psychology does not address the complexity of individual development and experience and fails to explain the influence of genes on behavior in individual cases.Critics assert that evolutionary psychology has trouble developing research that can distinguish between environmental and cultural explanation and adaptive evolutionary explanations. Some studies have been criticized for their tendency to attribute to evolutionary processes elements of human cognition that may be attributable to social processes (e.g. preference for particular physical features in mates), cultural artifacts (e.g. patriarchy and the roles of women in society), or dialectical considerations (e.g. behaviours in which biology interacts with society, as when a biologically determined skin colour determines how one is treated).

Evolutionary psychologists respond that their discipline is not primarily concerned with explaining the behavior of specific individuals, but rather broad categories of human behaviors across societies and cultures. It is the search for species-wide psychological adaptations (or "human nature") that distinguishes evolutionary psychology from purely cultural or social explanations. These psychological adaptations include cognitive decision rules that respond to different environmental, cultural, and social circumstances in ways that are (on average) adaptive.
Evolutionary psychologists Confer et al. argue the evolutionary psychology fully accept nature-nurture interactionism and that it possible to test the theories in order to distinguish between different explanations.
Adaptive explanations vs. other evolutionary mechanisms
Critics point out that within evolutionary biology there are many other non-adaptive pathways along which evolution can move to produce the behaviors seen in humans today. Natural selection is not the only evolutionary process that can change gene frequencies and produce novel traits. Genetic driftGenetic drift

Evolutionary psychologists suggest that critics mischaracterize their field, and that their empirical research is designed to help identify which psychological traits are likely to adaptations, and which are not.
Disjunction and grain problems
Some have argued that even if the theoretical assumptions of evolutionary psychology turned out to be true, it would nonetheless lead to methodological problems that would compromise its practice. The disjunction and grain problems are argued to create methodological challenges related to the indeterminacy of evolutionary psychology’s adaptive functions. That is, the inability to correctly choose, from a number of possible answers to the question: “what is the function of a given mechanism?”The disjunction problem occurs when a mechanism appears to respond to one thing (F), but is also correlated with another (G). Whenever F is present, G is also present, and the mechanism seems to respond to both F and G. The difficulty thus involves deciding whether to characterize the mechanism's adaptive function as being related to F, G, or both. “For example, a frogs pre-catching mechanism responds to flies, bees, food pellets, etc.; so is its adaptation attuned to flies, bees, fleebees, pellets, all of these, or just some?”
The grain problem refers to the challenge in knowing what kind of environmental ‘problem’ an adaptive mental mechanism might have solved. As summarized by Sterenly & Griffiths (1999): “What are the problems ‘out there’ in the environment? Is the problem of mate choice a single problem or a mosaic of many distinct problems? These problems might include: When should I be unfaithful to my usual partner? When should I desert my old partner? When should I help my sibs find a partner? When and how should I punish infidelity?” The grain problem therefore refers to the possibility that an adaptive problem may actually involve a set of nested ‘sub-problems’ “which may themselves relate to different input domains or situations. Franks states that "if both adaptive problems and adaptive solutions are indeterminate, what chance is there for evolutionary psychology?"
Franks also states that "The arguments in no sense count against a general evolutionary explanation of psychology." and that by relaxing assumptions the problems may be avoided, although this may reduce the ability to make detailed models.

Evolutionary psychologists have been accused of conflating "is" and "ought", and evolutionary psychology has been used to argue against social change (because the way things are now has been evolved and adapted), and to argue against social justice (e.g. the argument that the rich are only rich because they've inherited greater abilities, so programs to raise the standards of the poor are doomed to fail).

psychology students. The authors concluded that those who self-identified as adaptationists were much less conservative than the general population average. They also found no differences compared to non-adaptationist students and found non-adaptationists to express a preference for less strict and quantitative scientific methodology than adaptationists.

is the idea that what is found in nature is good. It was the basis for Social Darwinism, the belief that helping the poor and sick would get in the way of evolution, which depends on the survival of the fittest. Today, biologists denounce the Naturalistic Fallacy because they want to describe the natural world honestly, without people deriving morals about how we ought to behave -- as in: If birds and beasts engage in adultery, infanticide, cannibalism, it must be OK)."

The moralistic fallacy is in essence the reverse of the naturalistic fallacy.Naturalistic fallacy presumes that what is—or what occurs—forms what ought to be. Thus the observed natural is reasoned a priori as moral....
is that what is good is found in nature. It lies behind the bad science in nature-documentary voiceovers: lions are mercy-killers of the weak and sick, mice feel no pain when cats eat them, dung beetles recycle dung to benefit the ecosystem and so on. It also lies behind the romantic belief that humans cannot harbor desires to kill, rape, lie, or steal because that would be too depressing or reactionary."
Evolutionary psychology has been criticized by some feminists, such as Tang-Martinez, as justifying rape
Rape
Rape is a type of sexual assault usually involving sexual intercourse, which is initiated by one or more persons against another person without that person's consent. The act may be carried out by physical force, coercion, abuse of authority or with a person who is incapable of valid consent. The...

Cancer , known medically as a malignant neoplasm, is a large group of different diseases, all involving unregulated cell growth. In cancer, cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. The cancer may also spread to more distant parts of the...
