This book discusses individual differences in how people react to uncertainty. The authors show that while some people are relatively comfortable dealing with uncertainty and strive to resolve it (uncertainty-oriented), others are more likely to avoid uncertainty, preferring the familiar or the known (certainty-oriented). They go on to examine the implications of an uncertainty orientation for understanding processes of self-knowledge, social cognition and attitude change, achievement, motivation and performance, interpersonal and group processes, and issues relating to physical and psychological health concerns. Research is discussed which links this uncertainty orientation to each of these issues, raising important practical and theoretical questions for each. The book also considers possible implications for people of both orientations of living in times that may be characterized as being uncertain.
