In the World Library of Psychologists series, international experts themselves present career-long collections of what they judge to be their finest pieces – extracts from books, key articles, salient research findings, and their major practical theoretical contributions.In this volume Arie Kruglanski reflects on the development throughout his distinguished career of his wide-ranging research covering radicalisation, human judgement and belief formation, group and intergroup processes, and motivated cognition. This collection offers an invaluable insight into the key works behind the formation of Kruglanski’s seminal theory of lay epistemics, as well as his important input into a diverse range of fields of social psychology. A specially written introduction gives an intimate overview of this career, and contextualises the selection in relation to changes in the field during this time.With continuing relevance today, and of vast historical importance, this collection is essential reading for anyone with an interest in goals, belief formation, group processes, and social psychology in general.
