Given recent controversy over the replicability of and statistical power required to detect priming effects, the aim of this synthesis is to develop recommendations for statistical power for future research with the WIT paradigm. In developing these recommendations, the present article first quantitatively ascertains the magnitude of publication bias in the extant literature. Next, expected effect sizes and power recommendations are generated from a meta-analysis of the extant literature. Finally, a close conceptual replication of the WIT paradigm is conducted to prospectively test these recommendations. Racial priming effects are detected in this prospective test, providing increased confidence in the WIT priming effect and credibility to the proposed recommendations for power.
