Here’s a cool article against gender essentialism by the author of Pink Brain, Blue Brain:
Yes, boys and girls, men and women, are different. But most of those differences are far smaller than the Men are from Mars, Women are from Venus stereotypes suggest. Nor are the reasoning, speaking, computing, empathising, navigating and other cognitive differences fixed in the genetic architecture of our brains. All such skills are learned, and neuro-plasticity – the modification of neurons and their connections in response to experience – trumps hard-wiring every time. If men and women tend towards different strengths and interests, it is due to a complex developmental dance between nature and nurture that leaves ample room to promote non-traditional skills in both sexes.
For the record, this idea is echoed by all sorts of gender types, including myself, but the most interesting evidence is in Hyde’s Gender Similarities Hypothesis (pdf).
