Prejudice is a topic of major interest to psychologists and sociologists, but had rarely been given the broad treatment its importance demanded.

Originally published in 1985, this title first introduces the term, showing how it is related to other terms commonly used in psychology and the social sciences, and explains simply and clearly what a scientific analysis must involve. It then goes on to show how prejudice affects our reasoning and judgement in a wide variety of spheres in addition to race or ethnic attitudes. Next it traces the development of prejudiced attitudes towards black people in Britain and the New World, through the slave system and the slave trade, with a brief look at the remarkably similar development of ethnic attitudes in South Africa at the time. It then goes on to discuss the debate about race differences in intelligence, showing simply and clearly what the statistical assumptions underlying the heritability hypothesis are. Following that the psychological explanation of prejudice and principles explaining prejudice are spelled out, the question of sex prejudice is dealt with, and finally, the extent of ethnic prejudice in Britain and the USA is discussed. The final chapter is a summary of the general principles and conclusions discussed through the book.

This title provides a scientific and historical perspective on prejudice, a thorough literature review, and clear summarising principles of prejudice, in a simple and straightforward style.
