    Parasite-stress promotes in-group assortative sociality: The cases of strong family ties and heightened religiosity.Corey L. Fincher & Randy Thornhill - 2012 - Behavioral and Brain Sciences 35 (2):61-79.
    Throughout the world people differ in the magnitude with which they value strong family ties or heightened religiosity. We propose that this cross-cultural variation is a result of a contingent psychological adaptation that facilitates in-group assortative sociality in the face of high levels of parasite-stress while devaluing in-group assortative sociality in areas with low levels of parasite-stress. This is because in-group assortative sociality is more important for the avoidance of infection from novel parasites and for the management of infection in (...)

    Human facial beauty.Randy Thornhill & Steven W. Gangestad - 1993 - Human Nature 4 (3):237-269.
    It is hypothesized that human faces judged to be attractive by people possess two features—averageness and symmetry—that promoted adaptive mate selection in human evolutionary history by way of production of offspring with parasite resistance. Facial composites made by combining individual faces are judged to be attractive, and more attractive than the majority of individual faces. The composites possess both symmetry and averageness of features. Facial averageness may reflect high individual protein heterozygosity and thus an array of proteins to which parasites (...)

    The parasite-stress theory may be a general theory of culture and sociality.Corey L. Fincher & Randy Thornhill - 2012 - Behavioral and Brain Sciences 35 (2):99-119.
    In the target article, we presented the hypothesis that parasite-stress variation was a causal factor in the variation of in-group assortative sociality, cross-nationally and across the United States, which we indexed with variables that measured different aspects of the strength of family ties and religiosity. We presented evidence supportive of our hypothesis in the form of analyses that controlled for variation in freedom, wealth resources, and wealth inequality across nations and the states of the USA. Here, we respond to criticisms (...)

    Sex Differences in Detecting Sexual Infidelity.Paul W. Andrews, Steven W. Gangestad, Geoffrey F. Miller, Martie G. Haselton, Randy Thornhill & Michael C. Neale - 2008 - Human Nature 19 (4):347-373.
    Despite the importance of extrapair copulation (EPC) in human evolution, almost nothing is known about the design features of EPC detection mechanisms. We tested for sex differences in EPC inference-making mechanisms in a sample of 203 young couples. Men made more accurate inferences (φmen = 0.66, φwomen = 0.46), and the ratio of positive errors to negative errors was higher for men than for women (1.22 vs. 0.18). Since some may have been reluctant to admit EPC behavior, we modeled how (...)

    Immigration, parasitic infection, and United States religiosity.Jaimie N. Wall, Todd K. Shackelford, Corey L. Fincher & Randy Thornhill - 2012 - Behavioral and Brain Sciences 35 (2):97.
    Fincher & Thornhill (F&T) present a powerful case for the relationship between parasite-stress and religiosity. We argue, however, that the United States may be more religious than can be accounted for by parasite-stress. This greater religiosity might be attributable to greater sensitivity to immigration, which may hyperactivate evolved mechanisms that motivate avoidance of potential carriers of novel parasites.

    Is There Psychological Adaptation to Rape?Randy Thornhill - 1994 - Analyse & Kritik 16 (1):68-85.
    Psychological adaptation underlies all human behavior. Thus, rape could either arise from a rape-specific psychological adaptation or it could be a side-effect of a more general psychological adaptation not directly related to rape. The rape-specific hypothesis and the incidental effect hypothesis are explained. Determinig the specific environmental cues that men's sexual psyche has been designed by selection to process will allow us to decide which of these two hypotheses is true. I focus on rape, and briefly look at other types (...)
