“Gaydar” — the purported ability to infer whether people are gay or straight based on their appearance — seemed to get a scientific boost from a 2008 study that concluded people could accurately guess someone’s sexual orientation based on photographs of their faces. In a new paper researchers at the University of Wisconsin-Madison challenge what they call “the gaydar myth.” William Cox, an assistant scientist in the Department of Psychology and the lead author, says gaydar isn’t accurate and is actually a harmful form of stereotyping.
Looking at measurements of the vertebrae – the series of small bones that make up the spinal column – in newborn children, investigators at Children’s Hospital Los Angeles found that differences between the sexes are present at birth. Results of the study suggest that this difference is evolutionary, allowing the female spine to adapt to the fetal load during pregnancy.
Stereotypes about people can affect how we look at a person, but sometimes it causes other problems. Gender stereotypes about women’s ability in mathematics negatively impact their performance. And in a significant twist, both men and women wrongly believe those stereotypes will not undermine women’s math performance — but instead motivate them to perform better.
