This chapter examines the constructs that underlie prejudicial beliefs, including how individuals come to learn to hold such views, group-level predictors, and individual-level psychological attributes that have been shown to correlate with those predictors and ultimately, prejudice. First, indoctrination and groupthink are explored as ways that individuals come to adopt such views, most commonly through limiting their reasoning to binary thought processes. Then research on predictors such as religious extremism, right wing political orientation, and authoritarianism is reviewed which may explain ingroup favoritism and outgroup derogation, most commonly towards those of other races, ethnicities, cultures, religions, or sexual orientation. The chapter concludes with a discussion of individual-level psychological attributes associated with the group-level predictors and ultimately with a tendency to hold discriminatory views. These include the dichotomy between analytic and intuitive cognitive styles, directional motives driven by confirmation bias, and cognitive ability as defined by intelligence level and cognitive flexibility. By examining the reasons that people may choose to adopt prejudicial views, we may be able to develop methods to address such occurrences and limit the spread of discrimination.
