Accuracy in judging personality is important in clinical assessment, applied settings, and everyday life. Personality judgments are important in assessing job candidates, choosing friends, and determining who we can trust and rely on in our personal lives. Thus, the accuracy of those judgments is important to both individuals and organizations. In examining personality judgment, this book takes a sweeping look at the field’s history, assumptions, and current research findings. The book explores the construct of traits within the person-situation debate, defends the human judge in the face of the fundamental attribution error, and discusses research on four categories of moderators in judgment: the good judge, the judgeable target, the trait being judged, and the information on which the judgment is based. Spanning two decades of accuracy research, this book makes clear not only how personality judgment has come to its current standing but also where it may move in the future.
