“Although gender differences on average are not under dispute, the idea of consistently and inflexibly gender-typed individuals is,” Bobbi J. Carothers of Washington University in St. Louis and Harry T. Reis of the University of Rochester explained in their study. “That is, there are not two distinct genders, but instead there are linear gradations of variables associated with sex, such as masculinity or intimacy, all of which are continuous.”

Analyzing 122 different characteristics from 13,301 individuals in 13 studies, the researchers concluded that differences between men and women were best seen as dimensional rather than categorical. In other words, the differences between men and women should be viewed as a matter of degree rather than a sign of consistent differences between two distinct groups.

“Researchers scare ‘fearless’ patients. Weird science for today. People with amygdala lesions don’t experience fear — they walk in the middle of the street because they are not afraid of getting hit by cars. But if you make them breathe air with extra carbon dioxide, which in normal people just causes them to try to breathe harder, in people with amygdala lesions causes panic attacks.”
