With profound insight into the complexities of the human experience, Harvard psychologist Gordon Allport organized a mass of research to produce a landmark study on the roots and nature of prejudice. First published in 1954, The Nature of Prejudice remains the standard work on discrimination. Now this classic study is offered in a special unabridged edition with a new introduction by Kenneth Clark of Columbia University and a new preface by Thomas Pettigrew of Harvard University.Allport’s comprehensive and penetrating work examines all aspects of this age-old problem: its roots in individual and social psychology, its varieties of expression, its impact on the individuals and communities. He explores all kinds of prejudice-racial, religious, ethnic, economic and sexual-and offers suggestions for reducing the devastating effects of discrimination.The additional material by Clark and Pettigrew updates the social-psychological research in prejudice and attests to the enduring values of Allport’s original theories and insights.
