According to Hines, this isn’t what we see. Tallying all the scientific data she has seen across all ages, Hines believes that the “sex difference in empathizing and systemizing is about half a standard deviation.” This would be equivalent to a gap of about an inch between the average heights of men and women. It’s small. “That’s typical,” she adds. “Most sex differences are in that range, And for a lot of things, we don’t show any sex differences.”
