Humans and animals learn from experience by reducing the probability of sampling alternatives with poor past outcomes. Using simulations, J. G. March (1996) illustrated how such adaptive sampling could lead to risk-averse as well as risk-seeking behavior. In this article, the author develops a formal theory of how adaptive sampling influences risk taking. He shows that a risk-neutral decision m...

Many animal species besides humans show evidence of individuality. Knowing how a risk-taker differs from its stay-at-home counterpart could not only help humans live more easily with our fellow creatures, says Lee Dugatkin of the University of Louisville, but also tell us a few things about ourselves and how we got this way.

The role of risk taking in building trust relations has largely been overlooked in the burgeoning literature on trust in the social sciences, yet it is central to understanding how trust develops. We argue that a series of risk taking behaviors is indispensable to building a trust relation. Experiments were conducted in Japan and the United States to examine the independent and cross-cultural e...

Power has been found to increase risk-taking (Anderson & Galinsky, 2006) but this effect appears to be moderated by individual differences in power motivation (Maner, Gailliot, Butz, & Peruche, 2007). Among individuals high in power motivation, the experience of power leads to more conservative decisions. As testosterone is associated with the pursuit of power and status (Dabbs & Dabbs, 2000), ...

We explore how the interconnected nature of global finance affects corporate risk taking. We show that a common global factor known to be associated with fluctuations in cross-border banking is also strongly associated with common comovements in corporate risk-taking across a diverse universe of international firms. Our study contributes to the international business literature as the first com...

background glucocorticoids taken orally increase the risk of fractures. it has been noted that a dose as low as 2.5 mg/day increases the risk of vertebral fracture. what is less clear is the possible influence of other risk factors for osteoporosis on the presence of non-vertebral fractures in patients taking glucocorticoids. objectives a cross-sectional study, performed on 513 men and women fr...

conclusions the results of this study suggested that parental monitoring and affiliation with deviant peers largely explained sexual risk taking among adolescents. therefore, prevention efforts aimed at reducing risky sex should compose of these factors. in fact, the results suggested that earlier prevention efforts may be warranted. results according to the results, about one-fifth of subjects...

OBJECTIVES This study examined the roles of identity formation and moral identity in predicting college student mental health (anxiety and depressive symptoms), health-risk behaviors (hazardous alcohol use and sexual risk taking), and psychological well-being (self-esteem and meaning). METHOD The sample comprised 9,500 college students (aged 18-25 years, mean = 19.78, standard deviation = 1.6...
