http://www.edge.org/3rd_culture/debate05/debate05_index.html This is a really great debate between two psychologists about the factors that may be relevant to gender disparities in the sciences including the studies of bias, discrimination and innate and acquired differences. It's very long and complex but I recommend reading it to anyone even slightly interested in the subject. Truly a worthy read :) And I'm very interested in who do you think won the debate :)
