Antisocial Personality Disorder as a Form of Adaptive Strategy

Abstract

Background: in contemporary domestic psychiatry the evolutionary explanations of antisocial personality disorder are practically lacking. The aim of study: the analysis of the significant concepts of the evolutionary approach to understanding the origins and typology of antisocial, or dissocial, personality disorder. Material and methods: a narrative review of contemporary English-language psychiatric and psychological literature using all available search engines using the keywords “antisocial psychopathy” and “evolutionary psychiatry and psychology”. Discussion and conclusion: in English-language psychiatric and psychological literature the affective component of antisocial traits, emphasized only in ICD-10, is called “primary psychopathy,” while the behavioral component of antisocial traits, associated with “sensation seeking” and “hyperactivation,” is called “secondary” psychopathy. Evolutionary and ecological approaches emphasize the adaptive role of aggressive and antisocial behavior, viewing such behavior as a “high-risk strategy” in social and sexual competition, as “costly” but potentially adaptive (rather than as “behavioral dysfunctions”). The understanding of persistent antisocial behavior as a social “trickster” strategy exploiting the trust and cooperative behavior of others is based on the R. Axelrod-W. Hamilton “iterated” prisoner’s dilemma. In the Prisoner’s Dilemma evolutionary model, the player’s payoff is determined by the effects on “fitness”: survival and fertility. Participating in several interactions with individuals, an antisocial “deceiver” with high mobility is able to exist, manifesting itself with a fairly low frequency in the population. Non-cooperative behavior in both animals and humans reduces the fitness of others and includes aggressive behavior, deception, betrayal, predation and social parasitism. From the point of view of the concept of “economic games,” people with subclinically expressed primary psychopathic traits (emotional coldness, manipulativeness, Machiavellianism) are represented as “strategists” with cooperation partners: they give with reciprocity to those partners whom they consider “highly valuable” (with the potential for great benefits in future), and only “take”, manipulating and deceiving, from those of “low value”. In a broad sense, evolutionary psychologists and psychiatrists find in the characteristics of antisocial individuals a predominance of a set of properties of “fast” life strategies, while the concept of “fast strategies” is also used to explain geographical differences in the prevalence of aggressive behavior.
