Robert B. Townsend, deputy director of the AHA, surveyed 2,240 associate and full professors of history and released the findings in this month's Perspectives on History. Female historians who were either married or had been married at the time of the 2010 survey took an average of 7.8 years to move from associate to full professor. Women who had never married were promoted in an average of 6.7 years. Almost two times as many of the female full professors listed their status as divorced or separated, which suggests their professional obligations were somehow less compatible with marriage than their male colleagues. They were also more likely than their male colleagues to have never wed at all.Conversely, male historians who were or had been married advanced in 5.9 years. The unmarried man took 6.4 years, a bit longer.
One more data point showing that 1. Women's lib is a myth which omly turns women into dried up crones and 2. the big problem in our society is that a family can no longer survive on one income.
I think that #1 is a fight of (wo)man against nature. Women want to be able to work jobs just the same as their male counterparts, but also want to have kids when they want. The two are not always compatible. While it may look like man has the upper hand in the short term, nature typically has its way in the end.
