Effects of aggregation on implicit bias measurement

Scholars debate the extent to which implicit bias is a stable individual attitude versus feature of social contexts. The primary evidence for context view that group averages are more stable, and strongly associated with disparate outcomes, than scores. Group averages, however, depend on aggregating many observations, raising question whether their apparently superior reliability validity may be statistical artefact aggregation. Would difference correlations as large context-based if we only aggregated measures per person? We report two studies testing effects repeated tests. find up six tests increases test-retest somewhat, but slightly, has no benefit after three Results suggest at level contexts cannot reduced multiple
