A pivotal figure in social psychology and personality studies for more than half a century, M. Brewster Smith was the recipient of the Gold Medal Award of the American Psychological Foundation for Lifetime Contributions by a Psychologist to the Public Interest. Smith has conducted groundbreaking work on the ways in which people's opinions are influenced by their strategies for coping with the world, with their social relations, and with their inner conflicts. His pioneering book, "Opinions and Personality", offered an in-depth treatment of how people's political opinions reflect and are partly shaped by the ways those views contribute to the functioning of their personalities. More recently, Smith has drawn on psychological research to suggest ways to reduce the threat of nuclear war. Throughout his work, Smith has aspired to an interdisciplinary social psychology that is scientific in its respect for empirical evidence and which can be applied to the social issues of our time. "For a Significant Social Psychology" collects Smith's most important writings, introduced by the author and presented thematically.
