Past research has shown that masculinity is linked to a greater number of sexual partners. Among men, lower F0 is linked to greater dominance, greater attractiveness, and a greater number of sexual partners - and a higher number of partners is linked to infidelity.Īlternatively, Schild and colleagues propose that masculinity might play a role in the link between lower voice pitch and infidelity among both men and women. This may suggest that fundamental frequency is a cue that women use to judge whether a man is likely to cheat or not, in order to avoid the costs of being involved with an uninvested partner.įindings from past research might shed light on why men with lower voices appear to be more unfaithful. The authors note that a previous study also led by Schild found that women were able to accurately predict a male speaker’s cheating behavior based on the pitch of his voice. The study authors report, “lower mean F0 predicted lower vocal attractiveness, which in turn predicted a higher likelihood of self-reported infidelity.” The same effect was not found for men. Among women, ratings of vocal attractiveness were found to partially explain the link between F0 and likelihood of cheating. The upper and lower ranges of voice pitch (F0 max and F0 min) and the variability of pitch (monotonicity) were not found to be predictors of infidelity.Ī mediation analysis further suggested a potential mechanism in play. 2020) revealed that lower mean F0 was linked to increased reports of infidelity among men and women. Next, a meta-analysis of the three datasets (and additional data from Schild et al. 2011), both men and women with lower mean F0 were more likely to report past cheating behavior, and also reported a higher number of sexual partners outside a committed relationship. However, for one of the datasets (Asendorpf et al. Among two of the datasets, mean F0 (average voice pitch) did not significantly predict cheating behavior. Researchers first reanalyzed the three datasets.
