How male and female brains diverge is a hotly debated topic, but the study of model organisms points to differences that cannot be ignored.
“We have raised our children in a gender-neutral household since the day they were born, and we never allowed any sort of weapons, not even a water pistol,” a young mother told me emphatically from the microphone in the lecture hall where I’d just given a talk on the differences between male and female brains. “But the other day my seven-year-old son bit his peanut butter and jelly sandwich into the shape of a gun and started shooting his little sister with it!” The audience laughed appreciatively; everyone had a similar story. “What did we do wrong?” she pleaded.
This story is a common refrain I hear when discussing my research on sex differences in the brain. There is no single correct answer when it comes to human behavior. Some researchers would insist that there is nothing parents can do to suppress the innate tendencies of boys to gravitate to guns and trucks while girls prefer dolls and tea sets. Others would disagree, arguing that there is no inherent biological difference between the brains of boys and girls. Rather, it is the parents’ own implicit biases and those of society at large that influence their children to behave in gender-typical ways. In the end, my response is that sex differences in the brain are more than some would like and less than others believe.
