A comprehensive evolutionary framework for understanding the maintenance of heritable behavioral variation in humans is yet to be developed. Some evolutionary psychologists have argued that heritable variation will not be found in important, fitness-relevant characteristics because of the winnowing effect of natural selection. This article propounds the(More)
We examined the effect of an image of a pair of eyes on contributions to an honesty box used to collect money for drinks in a university coffee room. People paid nearly three times as much for their drinks when eyes were displayed rather than a control image. This finding provides the first evidence from a naturalistic setting of the importance of cues of(More)

The Americas harbor a very great diversity of indigenous language stocks, many more than are found in any other continent. J. Nichols [(1990) Language 66, 475-521] has argued that this diversity indicates a great time depth of in situ evolution. She thus infers that the colonization of the Americas must have begun around 35,000 years ago. This estimate is(More)
Heritable individual differences in personality have not been fully accounted for within the framework of evolutionary psychology. This paper argues that personality axes such as extraversion can usefully be seen as dimensions of trade-off of different fitness costs and benefits. It is hypothesized that increasing extraversion will be associated with(More)
Human cognition is often biased, from judgments of the time of impact of approaching objects all the way through to estimations of social outcomes in the future. We propose these effects and a host of others may all be understood from an evolutionary psychological perspective. In this article, we elaborate error management theory (EMT; Haselton & Buss,(More)
Empathizing and systemizing have recently been put forward as two important individual-difference dimensions, whose different mean levels in men and women are argued to account for many psychological sex differences. This paper presents a series of studies designed to investigate the reliability and validity of the empathizing and systemizing quotients (EQ(More)
There is an evolutionary puzzle surrounding the persistence of schizophrenia, since it is substantially heritable and associated with sharply reduced fitness. However, some of the personality traits which are predictive of schizophrenia are also associated with artistic creativity. Geoffrey Miller has proposed that artistic creativity functions to attract(More)
There has been a recent surge of interest in the evolutionary basis of depression. One approach argues that the affective mechanisms that are dysregulated in depression are adaptations, whilst a second approach argues that depression itself is an adaptation. The evidence relating to whether depression could itself be an adaptation is reviewed. Adaptations(More)
