Specificity and incremental predictive validity of implicit attitudes: studies of a race-based phenotype

Cognitive Research: Principles and Implications

Table 5 Results of Bayesian meta-analyses probing the mean levels of implicit hair attitudes, self trait judgments, societal trait judgments, and legal judgments among African American and White American participants (Studies 1–4)

	African American participants		White American participants
	Cohen’s d	BF₁₀	Cohen’s d	BF₁₀
Black hair attitude IAT	0.22 [0.12; 0.31]	7.72 × 10³	0.68 [0.64; 0.73]	6.42 × 10¹⁹¹
Self trait judgments	− 0.63 [− 0.73; − 0.55]	2.32 × 10³¹	− 0.31 [− 0.33; − 0.28]	2.30 × 10³⁹
Societal trait judgments	1.42 [1.34; 1.56]	1.80 × 10¹¹⁰	1.09 [1.01; 1.13]	5.33 × 10³⁴⁴
Legal judgments	− 1.85 [− 1.98; − 1.73]	1.85 × 10¹⁴⁹	− 1.15 [− 1.21; − 1.11]	4.75 × 10³⁷⁷

Cohen’s d effect sizes are scored such that more positive scores indicate higher levels of bias in favor of Eurocentric hair texture. 95-percent HDIs (highest density intervals) are reported in square brackets. BF₁₀ refers to Bayes Factors providing a relative measure of evidence in favor of the alternative hypothesis (μ ≠ 0) over the null hypothesis (μ = 0)
