Facial symmetry may play role in perception of sexual orientation

The study showed the photographs of 60 men and women, 15 straight men, 15 straight women, 15 gay men and 15 lesbians, to a group of 40 participants (15 men, 25 women) who assessed the sexual orientation of those seen in the photographs.

The raters indicated the gender to which the person in the picture was most sexually attracted using a five-point continuum scale (1-only men, 2-mostly men, some women, 3-men and women equally, 4-mostly women, some men, 5-only women).

Likewise, the researchers found that there was a tendency for straight women to be more symmetrical, although it was not statistically significant.

The study has been published in The Journal of Social, Evolutionary, and Cultural Psychology. (ANI)
