Need for closure effect on collective action intentions and behavior toward immigrants in Italy:The mediation of binding foundations and political conservatism

Why are people (de)motivated to mobilize in favor of immigrants? Addressing this question, we investigated the role of individuals' epistemic motivation (i.e., need for closure) in influencing the process of becoming motivated to participate in collective action in favor of immigrants in Italy. Specifically, the mediational role of binding moral foundations and political conservatism in explaining the relationship between need for closure and collective action in favor of immigrants was examined in three studies. It was hypothesized that a heightened need for closure would be indirectly and negatively associated with collective action in favor of immigrants, sequentially mediated first through binding moral foundations and then political conservatism. We found support for this prediction when either dispositional measure (Study 1 and Study 2) or an experimental induction (Study 3) of need for closure were used, and when both collective action intentions (Study 1 and Study 3) and behavior (Study 2) were assessed. The results suggest that need for closure constitutes a powerful motivational force that leads individuals to engage in uncertainty‐reducing evaluations and actions. We discuss these results regarding how they are related with previous work and their implications for research and practice

Risk communication and non-linearity

This article will consider non-linearity and hormesis from the perspectives of risk perception and risk communication. The observations that follow do not come from a scientist or researcher. (For a richer academic treatment of the issue of risk communication and nonlinearity, see BELLE, Vol. 11, Issue 1, 2002). I was for 25 years a journalist on television and in print, focusing on coverage of environmental issues. I then studied and taught risk perception and risk communication at the Harvard School of Public Health. I now independently consult in these areas. From the academic side, I have read a fair amount of the literature that helps explain what I call ‘The Perception Gap,’ the gap between our fears and the facts. And as a journalist and consultant I have witnessed in the real world, people’s relatively greater fear of lesser risks, and relatively lower fear of the risks the scientific data suggest they ought to worry about more. I offer the following perspectives based on those foundations. </jats:p
