Query: Please, do more research than this book

A lot of the research that Dr. Sax is quoting is seriously generalized. There is very little research that has been done on children's brains, so many of the claims he is making about boys and girls is actually based on research done on adult men and women. some of his claims are even based on research done on rats. He obviously has to cite all these claims, so it's easy to look up for yourself. Be wary of his advice.
