“…In species like humans where risk-taking may itself become a form of display, this sex difference may be exaggerated and risk-taking may characterize many aspects of behavior. Many studies have noted that young human males are more prone than females to take risks in relation to conflict (Campbell, 1999; Daly and Wilson, 1988; Wilson and Daly, 1993,) and sexual behavior (Clift, Wilkins, and Davidson, 1993; Poppen 1995), as well as in such situations as car driving (Chen, Baker, Braver, and Li, 2000; Flisher, Ziervogel, Charlton, Leger, and Roberston, 1993; Harre, Field, and Kirkwood, 1996), accident risk (Fetchenhauer and Rohde, 2002), drug-taking (Tyler and Lichtenstein, 1997), gambling and financial decisions (Bruce and Johnson, 1994, Powell and Ansic, 1997) and outdoor activities (Howland, Hingson, Mangione, and Bell, 1996, Wilson, Daly, Gordon, and Pratt, 1996). Indeed, psychological studies have found that females find risky situations more stressful than males do (Kerr and Vlaminkx, 1997).…”
