Recently, behavioral and psychological researchers have taken an interest in facial morphology – that is, how the shape of the human face may correlate with certain attitudes, behaviors, and personality traits.
New research – led by Steven Arnocky, of Nipissing University in Ontario, Canada – examines the role of men and women’s FWHR in sexual relationships, infidelity, and mate selection.
To the authors’ knowledge, this is the first time that research links human FWHR to sex drive and sexual psychology.
Although the study is purely observational and cannot explain causality, the researchers point to testosterone as a factor that may be responsible for the results.
The team also notes some limitations to the study. Firstly, the population sample was quite limited. The scientists chose university students on the assumption that sexual interest is high in early adulthood, but this assumption is debatable.
Future studies should therefore aim to examine whether or not the results would be the same in adolescence or in later adulthood.
Secondly, the measure for infidelity was, the authors concede, quite restricted. Only two items in the questionnaire addressed this issue.
Finally, the authors suggest that future research should account for other factors that may influence sexual behavior, such as conservative beliefs about sex or sexual passivity.
