A new study that examines the connection between gender and finance is raising some eyebrows. Could it be that your tolerance for risk in money and career is determined by your hormones?

Researchers at Northwestern and the University of Chicago are publishing their findings in an upcoming issue of Economic Sciences:

“Higher-testosterone women are more prone to take risk, and this attitude is correlated with riskier career choices,” says Paola Sapienza, associate professor at Northwestern’s Kellogg School of Management and co-author of the study with Luigi Zingales of the University of Chicago.

Those risks sometimes translate to higher pay but also higher rates of unemployment, the study says.

The difference was not due strictly to gender, either. The 90 percent of women and 31 percent of men measured with low testosterone levels were equal in their risk-aversion. And in terms of solvency, the differences between the sexes were negligible: Surveys indicate that 10 percent of men and 11 percent of women report having filed for bankruptcy at some point in their lives.

But if you’re chock full of testosterone and itching to, say, use your savings to play the lottery, try to keep your impulses in check and put your money somewhere a little safer.
