AUTHOR=Liu Jie , Zhang Yanyan TITLE=Singles' similarity preferences in an ideal partner: What, when, and why JOURNAL=Frontiers in Psychology VOLUME=Volume 14 - 2023 YEAR=2023 URL=https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2023.1088591 DOI=10.3389/fpsyg.2023.1088591 ISSN=1664-1078 ABSTRACT=This study investigated singles’ similarity preference concerning their ideal partner’s personality traits, physical attractiveness, social resources as well as potential moderators (fear of being single and mate value) and mediators (forecasted satisfaction). With 1014 Chinese singles, we found that singles preferred their ideal partner to share similarities in the HEXACO traits, physical attractiveness, and social resources, and they preferred higher similarity in Honesty-Humility and Openness to Experience. Fear of being single, mate value, and forecasted satisfaction did not affect similarity preference on Honesty-Humility and Openness to Experience but had some mixed influence over similarity preference on other features.
