It has always been common sense to believe that boys and girls are different, yet modern “intellectuals” have been questioning these basic truths, blaming “social conditioning” for the cause of gender differences. Today I sit down with Dr. Leonard Sax, MD PhD, to debunk common myths about gender. We discuss how boys and girls have different brain development, how boys’ and girls’ play preferences compare to male and female chimpanzees, and how multi-generational communities form children with the development they need to mature well.
