Description
Arie Kruglansky presents his theoretical and empirical work on the need for assured knowledge and the central role it plays in human social behavior, on individual and group levels of analysis. The need for assured knowledge labeled more technically as the Need for Closure constitutes a fundamental mechanism whereby the potentially interminable epistemic sequence of hypothesis generation and testing comes to an end, affording one a sense of firm knowledge. Arousal of such a need (e.g. by uncertainty evoking events) is shown to induce a state of close mindedness in which individuals are (1) less able to empathize with others, (2) intolerant of diversity, (3) centered on their in-group, and (4) hostile to out-groups. Thus, a psychological, individual-level, mechanism of knowledge formation is shown to be relevant to major societal phenomena, and to play a potentially significant role in the shaping of politics and history in the world at large.
