Interpersonal and intergroup contact approaches work best when combined rather than chosen between.
Evidence
The findings presented here indicate that interpersonal (Brewer & Miller, 1984; Miller, 2002) and intergroup (Hewstone & Brown, 1986) approaches are not incompatible, and should be employed conjunctively to produce the most effective intergroup contact that truly reaches “below the surface” (Allport, 1954/1979, p. 276; see Brown & Hewstone, in press, for a detailed review). — John F.
