Love Stinks: The Association between Body Odors and Romantic Relationship Commitment

Area of Science:

• Psychology
• Human Behavior
• Olfactory Science

Background:

• Anecdotal evidence suggests women's dislike of partner body odor (BO) during relationship decline.
• Empirical testing of the link between disliking partner BO and breakup intentions is lacking.

Purpose of the Study:

• To investigate the association between disliking a partner's BO and experiencing lower commitment in romantic relationships.
• To explore the relationship between olfactory perception and romantic relationship dynamics.

Main Methods:

• Eighty participants (partnered and previously partnered) completed questionnaires on relationship commitment and partner BO exposure/ratings.
• Olfactory function was assessed, and participants rated stranger's BOs on clothing.
• Self-report measures of relationship history and partner odor perception were utilized.

Main Results:

• Among those who had broken up, higher past commitment correlated with more favorable ratings of a previous partner's BO.
• Currently partnered individuals with lower commitment showed higher breakup intentions when exposed to their partner's BO.
• Preliminary findings indicate a positive association between partner BO exposure and favorable odor appraisals, but nuances require further study.

Conclusions:

• Lower relationship commitment is associated with increased breakup intentions in response to a partner's BO.
• Exposure to a partner's BO may be more indicative of commitment than the hedonic quality of the BO itself.
• Findings suggest potential implications for understanding and intervening in relationship breakdown through odor perception.
