What on first inspection seemed like a sex difference was actually a difference between white males and everyone else.She denies that men are bigger risk-takers. They might be more likely to go skydiving or tightrope walking, but then they usually take safety precautions so that it is not really so risky!
Women take risks in other ways, such as buying lottery tickets. White male risk-taking just seems riskier, because they are better able to control their risks.
She is confused. Men are willing to take more risks, but that does not mean that they are stupid about it.
