Washington: Wide-faced men may not bring out the best in you!
Interacting with a wide-faced man can cause people to act selfishly, a new study has found.
Scientists at the University of California, Riverside and several other researchers have previously shown that men with wider faces are more aggressive, less trustworthy and more prone to engaging in deception.
Now, in a series of four studies, the researchers found that individuals behave more selfishly when interacting with men with wider faces.
"This clearly shows that this behaviour is also socially driven, not just biologically driven," said Michael P Haselhuhn, an assistant professor of management at UC Riverside`s School of Business Administration, who is the lead author of the paper.
He co-authored the paper with Elaine M Wong, also an assistant professor of management at UC Riverside, and Margaret E Ormiston, an assistant professor of organisational behaviour at London Business School.
The new studies, published in the journal PLOS ONE, involved between 131 to 207 participants each.
In the first study, the researchers established a relationship between facial width-to-height ratio (fWHR) and general self-interest, demonstrating that men with higher fWHRs behaved more selfishly when dividing resources between themselves and a partner.
In two subsequent studies, the researchers examined the same decisions from the partner`s point of view and showed that partners change their own behaviour based on a target`s fWHR.
In the final study, they showed that the partners` behaviour, based on the targets` fWHR, leads the target to act in ways consistent with the partners` expectations.
This shows a link between men`s fWHR and behaviour, which otherwise may be attributed to biological factors, but is also a function of social responses to men`s facial structure.
