Of course it's not just women! Women (outside the community, that is) are more likely to respond that way than men, but that's from a study on both risk aversion and hyperbolic discounting which showed that "Women can't take small risks and men are creatures of the now", with both effects diminishing as scores on the Cognitive Reflection Test increased.

I now wonder what would happen if I asked a man on the street to choose between $500 immediately or $1 million in 10 years (= 113% annual interest) - a version that extreme wasn't in the original study, just the extreme version of the risk-aversion Q. I wouldn't expect it to work, but then I wouldn't have expected it to work with risk aversion either!
