Washington: A study by Michigan State University psychology researchers has indicated that women’s bias against male strangers increases when women are fertile, suggesting prejudice may be partly fuelled by genetics. "Our findings suggest that women``s prejudice, at least in part, may be a byproduct of their biology," said Melissa McDonald, a doctoral student and lead author on the paper. The researchers conducted scientific studies with two groups of women that investigated how women``s implicit attitudes toward men change across the menstrual cycle. They found that fertile women were more biased against men of different races and men of different social groups than men of their own group.
"This may be deeply ingrained at psychological levels," said Navarrete, "and may manifest itself particularly if women believe men from different racial and nonracial groups to be physically imposing and when women are most fertile." The study has been published online in Psychological Science. ANI
