Not surprisingly, most physicians did not admit to any racial biases explicitly. However, on the implicit measures of bias (IATs), most nonblack physicians demonstrated some degree of bias favoring whites over blacks. Participants’ scores on the race preference IAT showed a range of implicit race bias similar to previous experiments on nonphysicians.21,26 The new cooperativeness IATs were normally distributed and somewhat correlated with the well-studied race preference IAT, suggesting that they measure different but related components of race bias.
