Evidence

Of the 33 studies we have reviewed, 11 (33 percent) found positive effects, 14 (42 percent) found a mixture of positive effects and nonsignificant effects, 5 (15 percent) found only nonsignificant effects, one (3 percent) found mixed negative and nonsignificant effects, and 2 (6 percent) found negative effects on measures related to intergroup relations (Stephan & Stephan, 2004). Two of the three studies that had negative or partially negative effects were the only two published studies of preschool children. — , Rudman, Laurie A - On the Nature of…, 2640
