Roderick returns to Red Ice to discuss Testosterone Rex. Written by feminist Cordelia Fine, the book is a biased attempt to dismiss biological differences between the sexes. As Roderick explains, Testosterone Rex is politics first, and science second. Nevertheless, Testosterone Rex won the (once) prestigious Royal Society prize for book science book of the year. We discuss the many ways in which Fine used bad research to attack a complete straw man, and ponder what her motivations might be. The show covers much more, including gender neutral schools, children as political pawns, and the main problems with the modern university system.
