Institutional support matters most for contact but backfires under competition or unequal status.

Evidence

Moreover, further examination of Allport’s conditions suggests that institutional support may be an especially important condition for facilitating positive contact effects. Although the present analysis offers a relatively crude test, samples with structured programs showed significantly stronger contact–prejudice effects than the remaining samples, irrespective of whether they were rated as having conditions beyond authority support. … Hence, although authority support appears to play an important role, this condition should not be conceived of or implemented in isolation. Institutional support for contact under conditions of competition or unequal status can often enhance animosity between groups, thereby diminishing the potential for achieving positive outcomes from contact (see Sherif, 1966). Thus, consistent with Allport’s original contentions, we believe that optimal conditions for contact are best conceptualized as functioning together to facilitate positive intergroup outcomes rather than as entirely separate factors. — Thomas F.

Categorization

• XREF: Echoes Sherif’s Robbers Cave findings and connects to the ADDENDUM on sacrifice insofar as top-down authority structures can amplify, not dampen, intergroup hostility. — connects to: Even apartheid-era unequal-status contact reduced White prejudice — Thomas F. Pettigrew, Linda R. Tropp, A Meta-Analytic Test of Intergroup…, 226
• DEEPTHINKING: The reframing of optimal conditions as interacting, not additive, factors resists any one-sentence summary — a genuine reconceptualization of the theory’s structure.
