For one, women seem just as keen to take certain kinds of risks, like disagreeing with their friends on an issue or attempting to sell a screenplay. It’s just that, when surveys measure risk-taking in terms of things like unprotected sex or motorcycles, women tend to demur, since those types of activities are either more dangerous for women (the unprotected sex) or are less familiar to them (riding motorcycles).

In fact, when researchers measured risk using more stereotypically feminine risky behavior, such as “cooking an impressive but difficult meal for a dinner party,” women turned out to be just as, if not more, likely to take risks as men. “Maybe there isn’t anything so special about male risk taking, after all,” wrote the University of Melbourne professor Cordelia Fine in Nautilus.

Several prominent psychologists believe there are actually few psychological differences between men and women. Men, it would seem, are from Mars, and women are also from Mars but are nonetheless baffled by why our fellow Martians would opt to do things the ways they do. The major differences between the genders are that men are more aggressive, can physically throw things further, masturbate more, and are more comfortable with casual, uncommitted relationships. These very differences can help explain the disparity in sexual harassment.
