Disgust is derived from evolutionary processes to avoid pathogen contamination. Theories of gender differences in pathogen disgust utilize both evolutionary psychological and sociocultural perspectives. Drawing on research that suggests that masculine and feminine gender identities are somewhat orthogonal, we examine how gender identity intersects with pathogen disgust. In addition, building on evolutionary psychological and sociocultural accounts of how caregiving and parental investment affect pathogen disgust, we present a new measure of caregiving disgust and compare its properties across gender, parental status, and political ideology with those of a conventional pathogen disgust measure. This registered report finds that how masculinity and femininity affect disgust varies by gender, disgust domain, and their intersection; that parental status effects vary by disgust domain but not gender; that reframing disgust in terms of caregiving eliminates the gender gap in disgust; and that the caregiving frame unexpectedly strengthens the relationship between disgust and political ideology.
厌恶感源于进化过程，旨在避免病原体污染。性别差异在病原体厌恶感方面的理论，既利用了进化心理学的观点，也利用了社会文化的观点。借鉴表明男性和女性性别认同有些正交的研究，我们研究了性别认同如何与病原体厌恶感交叉。此外，基于进化心理学和社会文化对养育和父母投资如何影响病原体厌恶感的解释，我们提出了一种新的养育厌恶感测量方法，并比较了其在性别、父母身份和政治意识形态方面与传统病原体厌恶感测量方法的特性。本注册报告发现，男性气质和女性气质如何影响厌恶感因性别、厌恶感领域及其交叉而有所不同；父母身份的影响因厌恶感领域而异，但与性别无关；以养育的角度重新定义厌恶感消除了厌恶感中的性别差距；而且，养育框架出人意料地增强了厌恶感和政治意识形态之间的关系。
