Androphilia refers to sexual attraction and arousal to adult males, whereas gynephilia refers to sexual attraction and arousal to adult females. In Independent Samoa, androphilic males, most of whom are effeminate or transgendered, are referred to as fa’afafine, which means “in the manner of a woman.” Previous research has established that fa’afafine report significantly higher avuncular tendencies relative to gynephilic men. We hypothesized that Samoan fa’afafine might adopt feminine gender role orientations with respect to childcare activity. If so, then the (...) fa’afafine’s femininity might be a proximate mechanism for promoting their elevated avuncular tendencies. Our analyses indicated that fa’afafine had significantly higher willingness to assist in the childcare of nieces and nephews than childless women, mothers, or men, none of whom differed from each other on this measure. Thus, femininity does not appear to explain the fa’afafine’s pattern of avuncular tendencies, nor the women’s pattern of materteral (i.e., aunt-like) tendencies, relative to gynephilic men. We discuss how the fa’afafine “third” gender status might influence the expression of their elevated avuncular tendencies. (shrink)

Behavioral scientists routinely publish broad claims about human psychology and behavior in the world's top journals based on samples drawn entirely from Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. Researchers – often implicitly – assume that either there is little variation across human populations, or that these “standard subjects” are as representative of the species as any other population. Are these assumptions justified? Here, our review of the comparative database from across the behavioral sciences suggests both that there is (...) substantial variability in experimental results across populations and that WEIRD subjects are particularly unusual compared with the rest of the species – frequent outliers. The domains reviewed include visual perception, fairness, cooperation, spatial reasoning, categorization and inferential induction, moral reasoning, reasoning styles, self-concepts and related motivations, and the heritability of IQ. The findings suggest that members of WEIRD societies, including young children, are among the least representative populations one could find for generalizing about humans. Many of these findings involve domains that are associated with fundamental aspects of psychology, motivation, and behavior – hence, there are no obviousa priorigrounds for claiming that a particular behavioral phenomenon is universal based on sampling from a single subpopulation. Overall, these empirical patterns suggests that we need to be less cavalier in addressing questions ofhumannature on the basis of data drawn from this particularly thin, and rather unusual, slice of humanity. We close by proposing ways to structurally re-organize the behavioral sciences to best tackle these challenges. (shrink)
