Men who have wider faces relative to their facial height are more likely to engage in unethical behavior, according to a new study in the latest issue of the Proceedings of the Royal Society B.
The finding adds to the growing body of evidence that an individual’s genes and hormonal development can influence that person’s behavior. The research also supports that certain static physical characteristics — in this case, a man’s facial bone structure — may serve as reliable visual cues to behavior.
“Other researchers have found that differences in facial width-to-height ratio (WHR) emerge around puberty,” co-author Michael Haselhuhn told Discovery News. “As sex differences in facial structure, generally, are at least partially due to increased testosterone concentrations in boys, testosterone likely plays a role in determining facial WHR, specifically, as well.”
