Preliminary evidence for an aversion to atheists in long-term mating domains in the Southern United States (Journal of Social and Personal Relationships, full study paper, October 13, 2021)

The abstract notes in their study of the most religious area of the USA (the Southeast), atheists are perceived as the least desirable for long-term relationships. That perception is ascribed to the widespread religious belief that atheists are untrustworthy in relationships.

Abstract

The centrality of religiosity in selecting long-term mates suggests atheism could be undesirable for that context. Given recent findings suggesting several positive stereotypes about atheists, a largely distrusted group, individuals could prefer atheists in mating domains not emphasizing long-term commitment (i.e., short-term mating). Two studies tasked U.S. participants with evaluating long-term and short-term mating desirability of theists and atheists while assessing perceptions of their personalities. Study 1 indicated atheists were more desirable in short-term mating than long-term mating, though this preference did not translate to being preferred over theists. The pre-registered Study 2 demonstrated this effect is specific to physically attractive targets. Atheists were further perceived as more prone to infidelity, especially when attractive. Results are framed from an evolutionary perspective while discussing anti-atheist prejudice.

That goes against statistics showing atheists are amongst the lowest divorce percentage of “religious” groups.
