This new edition brings up-to-date a text which presents the changes in American racial attitudes during the second half of the 20th century. The book retains the division of racial attitudes into principles of equality, government implementation of those principles, and social distance, but adds questions concerning affirmative action and beliefs about sources of inequality. A conceptual section now opens the book, evidence on social desirability has been added, and a new chapter deals with cohort effects and with the impact of income, education, and gender. In key instances, randomized experiments are introduced that test hypotheses more rigorously than is ordinarily possible with survey data. Throughout, the authors have reconsidered earlier ideas as well as introducing new thinking.
