Supplemental Material for The Impact of Race on Assessor’s Ability to Differentiate Accurate and Inaccurate Witness Identifications: Areas of Vulnerability, Bias, and Discriminatory Outcomes

Controlling for Identification TypeANOVA using witness race (White, Black), lineup race (White, Black), juror race (White, Black), and identification decision type (identification, rejection) to predict signed confidence juror accuracy.The following effects were significant (replications of results from our primary analysis are marked with a *): *Significant main effect of lineup race (F(1,1123)=4.05,MSe = 5200.71,p =.04, p 2 = 0.004).*Significant main effect of witness race (F(1,1123)=8.88,MSe = 11407.93,p =.003, p 2 = .01).Significant main effect of juror race (F(1,1123)=5.16,MSe = 6624.27,p =.02, p 2 = .01),such that Black jurors (M = 43.72,CI[39.73,47.70], SE = 2.03) showed higher levels of signed confidence accuracy than White jurors (M = 39.31,CI[36.74,41.89], SE = 1.31).*Significant interaction between target race and witness race (F(1,1123)=49.65,MSe = 63771.82,p <.001, p 2 = .04).
