Discussion effects on racial attitudes

We predicted that discussion would enhance dominant group values, leading to increased polarization between homogeneously composed groups of high-, medium-, and low-prejudice high school subjects. In an experimental condition, group members made individual attitude judgments, discussed them, and remade judgments. Control groups discussed irrelevant materials before responding again to the attitude items. As predicted, discussion of the racial attitude items with others having similar attitudes significantly increased the gap between high- and low-prejudice groups.
