Dr. Hogan is an international authority on personality assessment, leadership, and organizational effectiveness. His theory-based work in personality measurement has contributed to the development of socioanalytic theory, which maintains that the core of personality is based on evolutionary adaptations. He is widely credited with demonstrating how personality factors influence organizational effectiveness in a variety of areas, ranging from organizational climate and leadership to selection and effective team performance.
As an iconoclastic observer of American psychology, Dr. Hogan maintains that personality is best examined from the perspective of the observer (reputation) rather than the actor (a person's identity). As a consequence, he asserts that personality tools should be evaluated in terms of how well reputations (defined by personality tests) predict behavior on the job and in relationships.
Dr. Hogan is the author of more than 300 journal articles, chapters and books including Personality and the Fate of Organizations (2006). His recent author, co-author, and editing credits also include: The Hogan Guide (2007), Personality: Theories and Applications (2008), The Handbook of Personality Psychology (1997), The Perils of Accentuating the Positive (2009), the Hogan Personality Inventory, the Hogan Development Survey, the Motives Values and Preferences Inventory, and the Hogan Business Reasoning Inventory.
