Those scientists are at it again, disturbing conventional wisdom.
New Scientist News - Risk-taking boys do not get the girls: "One idea is that risk-takers are advertising their fitness to potential mates by showing off their strength and bravery. This fits with the fact that men in their prime reproductive years take more risks. To test this idea, William Farthing of the University of Maine in Orono surveyed 48 young men and 52 young women on their attitudes to risky scenarios. Men thought women would be impressed by pointless gambles, but women in fact preferred cautious men (Evolution and Human Behaviour, vol 26, p 171)."
The piece suggests that risktaking impresses other males. That would establish a pecking order ,and we all know that women go for successful men.
(Note that at least the summary is chauvinistic--women are so stupid that they're impressed by stupidity coupled with risktaking. At the risk of being chauvinistic myself, perhaps women don't like the idea of cleaning up male messes.)
