Women's Choices, Not Abilities, Keep Them out of Math-Intensive Fields, Experts Argue

The question of why women are so underrepresented in math-intensive fields is a controversial one. In 2005, Lawrence Summers, then president of Harvard University, set off a storm of controversy when he suggested it could be due partly to innate differences in ability; others have suggested discrimination or socialisation is more to blame. Two psychological scientists have reviewed all of the evidence and concluded that the main factor is women's choices -- both freely made, such as that they'd rather study biology than math, and constrained, such as the fact that the difficult first years as a professor coincide with the time when many women are having children.
