I thought David's original question was interesting enough but then the thread has produced some very dubious assertions based on partial observations that seem to be focused upon work or study environments. I think people are good at spotting things that confirm their beliefs and good at ignoring things that refute them.

This is probably why the myth that men = empirical/technical, women = irrational/artistic persists.

For the record, I'm a man who quit chemistry at school as early as possible because it was too hard (chickened out), I shoot only with natural light and I've just washed up and put our boy to bed. My wife's at work and earlier she did some work toward her maths degree.
