Question 2

Some popular writers have been quick to assume that brain differences between men and women explain differences in behaviours in real life. For example, it has been concluded that brain differences explain why women would rather talk about feelings and men would rather talk about sports. Sex differences in the brain have been cited to explain men's resistance in asking for directions and women's willingness to ask for help when lost. What are three problems with conclusions such as these?
