I haven’t read The Observer for a couple of years. Remind me not to bother if I stray that way again. The above link,which has no science in it at all claims gender differences are learned and not given at birth. Some rot about Mars and Venus is claimed to have been influential. I just despair of this kind of useless blather. Women and men are equal and so is my blind mate – but I will still see us across the road and be amazed the dog gets him to the office. This form of equality has everything to do with us being born different and a social construction of equality. Last time I looked 10% of men and women have the ‘wrong brains’ for their sex (according to scans of activity). Some women are XY in genetic terms and so on. There is no nature versus nurture argument, it’s both, it’s complicated and epigenetics and even genetic cultural memory may be involved (this is speculative and the only work I know involves finches). It’s time to wake up from thinking dross has any part in emancipation, feminist or otherwise.
