Biases left unattended: People are surprised at racial bias feedback until they pay attention to their biased reactions

Why are people surprised at racial bias feedback, such as test results from Implicit Association Tests (IATs), even though they can predict their IAT scores prospectively? The present research tested three hypotheses: People feedback due to (1) the wording, (2) implicit evaluations often being preconscious and unattended, or because (3) pretending be is socially desirable. One pilot, four preregistered studies, a mini-meta-analysis supported hypothesis (2): Although biases those reflected on observable, rarely pay attention them. Specifically, predicting (Studies 2-4b) encouragement one's biased reactions before completion (Study 3) reduced surprise, independent of explanation “implicit bias” 4b). Contradicting social-desirability (3), neither admit in form abstract predictions 3), nor non-threatening explanations 4b), surprise absence own biases. Speaking against (1), was severity 1–3); prediction effect mediated by recognition bias, but not correspondence 3). These studies suggest that consequence nature automatic social cognitions: may motivated keep consciously accessible out awareness. Implications for theories cognition generality these effects beyond discussed.
