Based on the existing literature on worldview beliefs, cynical hostility, and Machiavellian cynicism, we suggest that holding cynical beliefs about human nature can be detrimental for individuals' income. Cynical individuals are more likely to avoid cooperation and trust or to overinvest in monitoring, control, and other means of protection from potential exploitation. As a result, they are more likely to forgo valuable opportunities for cooperation and consequently less likely to reap the benefits of joint efforts and mutual help compared with their less cynical counterparts. Studies 1 and 2, using nationally representative longitudinal surveys of the American population, show that individuals who endorsed cynical beliefs about human nature at baseline earned comparatively lower incomes 9 (Study 1) and 2 (Study 2) years later. In Study 3, applying a multilevel model of change to a nationally representative panel study of the German population, we show that cynical beliefs at baseline undermined an income increase in the course of the following 9 years. In Study 4, the negative effect of cynical beliefs on income proved to be independent of individual differences in the Big Five personality dimensions. Study 5 provided the first tentative evidence of the hypothesized mechanism underlying this effect. Using survey data from 41 countries, it revealed that the negative effect of cynical beliefs on income is alleviated in sociocultural contexts with low levels of prosocial behavior, high homicide rates and high overall societal cynicism levels. Holding cynical beliefs about others has negative economic outcomes unless such beliefs hold true.
This research investigates the relation between informal help and subjective well-being and its underlying mechanisms using a cross-national perspective. We focus on two potential mechanisms derived from the self-determination theory and conformity to the social norms literature. From the standpoint of self-determination theory, helping others is good for well-being if it is intrinsically motivated, rather than driven by the expectation of reciprocity. On the other hand, from the perspective of the conformity literature, helping others is associated with a higher well-being when it is linked to the benefits of social conformity, such as social approval. We tested these hypotheses using the data from a total of 23 countries. The results provided support for both mechanisms. First, we found that the lower individuals' beliefs in reciprocity are, the stronger is the positive effect of selfreported helping behavior on their well-being. Second, helping behavior was more strongly related to life satisfaction in countries where providing help represents a strong social norm (measured with two different cultural indicators). We conclude that both individual-and culture-level mechanisms account for the relation between prosocial behavior and well-being.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
