In 2000 a brief scientific article was published in the international journal Infant Behavior and Development describing an experiment that would shape the way people around the world thought about sex differences at birth. It was written by a team from the Departments of Experimental Psychology and Psychiatry at Cambridge University, which included Simon Baron-Cohen, a psychologist, neuroscientist, and famous expert on the medical condition autism. The paper claimed to prove for the first time that there were noticeable and important sex differences in the way newborn babies behaved.
