“In this smart, balanced, and wonderfully readable book, Angela Saini breaks the vicious cycle by which women, having been excluded from the sciences by men who assumed them to be inferior, were judged by those same male scientists to be inferior. Study by study, she objectively reexamines what we think we know about the supposed differences between the sexes. If you have ever been shouted down by a male colleague who insists that science has proven women to be biologically inferior to men, here are the arguments you need to demonstrate that he doesn’t know what he is talking about.” -- Eileen Pollack, author of The Only Woman in the Room
