Also this summer, Linda C. Babcock, an economics professor at Carnegie Mellon University, looked at gender and salary in a novel way. She recruited volunteers to play Boggle and told them beforehand that they would receive $2 to $10 for their time. When it came time for payment, each participant was given $3 and asked if that was enough.
Men asked for more money at eight times the rate of women.
In a second round of testing, where participants were told directly that the sum was negotiable, 50 percent of women asked for more money, but that still did not compare with 83 percent of men. It would follow, Professor Babcock concluded, that women are equally poor at negotiating their salaries and raises.
There are practical nuggets of advice in all this data.
Don’t be shy about negotiating. If you blow your stack, explain (or try). “Some of what we are learning is directly helpful, and tells women that they are acting in ways they might not even be aware of, and that is harming them and they can change,” said Peter Glick, a psychology professor at Lawrence University in Appleton, Wis.
