by Camilla Cavendish, Times Online, UK - The book raises intriguing questions. If Pinker is right, then women who have the luxury of making career choices may actually increase, not decrease, the sexual division of labour. That is certainly what happened in kibbutzes that were studied over four generations, where all choices were freely available to men and women but where, in each generation, men chose to do progressively less childcare and women less construction work. What does that mean for our current notions of equality? If women choose not to be corporate CEOs, does it matter? How can we find ways to better value what they do decide to do?
