Testing a perceived uncommitted mating strategy account for atheist distrust and marriage disapproval.

Recent research suggests presumptions about atheists' uncommitted mating strategy causes atheists to seem less trustworthy, and that people who are more religious or espouse less agreeable attitudes toward uncommitted mating (i.e., more restricted sociosexual attitudes) tend to harbor greater anti-atheist attitudes. We provided additional tests of these ideas and addressed whether they could extend to discrimination against atheists in a "high-trust domain:" likelihood of granting approval to marry one's adult child. An MTurk sample of U.S. parents (N = 301) self-reported their religiosity and sociosexual attitudes, then were randomly assigned to a condition wherein they read about their adult child's fiancé who was either depicted as an atheist or devoted Christian. Participants reported their likelihood of approving of their child marrying the fiancé and estimated the fiancé's committed mating strategy, trustworthiness, and dark personality characteristics. Participants with high religiosity presumed an atheist (vs. devoted Christian) fiancé endorsed a less committed mating strategy, which, apart from presumptions about the fiancé's standing on dark personality characteristics, was associated with (a) perceiving the atheist as less trustworthy and (b) indicating less approval for their child marrying an atheist. Broadly, the research extends theorizing on how atheism relates to perceived threats to moral values and discrimination. [ABSTRACT FROM AUTHOR]
