Uncommitted men match their risk taking to female preferences, while committed men do the opposite

Abstract

Previous research shows that men are more risk prone than women; single men take more risks than men involved in a romantic relationship; and men increase their level of risk taking in the presence of observers. We extend the existing literature with two studies. Our first study demonstrates that romantically involved men take less risk in the presence of women to the extent that they are more committed to their current partner. No such effect occurs in the presence of males. Our second study is an experiment revealing that men's beliefs about women's attitudes about risk taking causally influence men's level of risk taking. We developed a new measure of risk-taking—the Marble Risk Task, reminiscent of the computerized Balloon Analogue Risk Task ( Lejuez et al., 2002), but designed to measure risk-taking outside of the laboratory and with real financial stakes—to show that single men adjust their level of risk taking to match what they believe women find attractive. Men involved in a relationship did the opposite: they adjust their behavior to not match what they believe women consider attractive—possibly with the goal of relationship maintenance.
