I would add: 6. Males are far more likely to enter jobs they're not suitable for Of all the "programmers" without any aptitude that seem to plague corporate IT departments, virtually none of the ones I've come across have been female. If you take out these frauds when counting programmers, then the gender balance in many IT departments becomes more like the early 1980's. Added: When programming became a perceived status job, the frauds turned up to cheat aptitude tests, lie on their CV about experience and studies, and what not.
