This report summarizes the results of an online experiment that utilized an Implicit Association Test (IAT) to measure racial bias in single-race whites, blacks, Asians and biracial adults with a white and black or a white and Asian racial background. The study sought to measure subconscious racial bias in the five racial groups and to see if biracial adults unconsciously view one of their racial backgrounds more favorably than the other. Pew Research Center worked with professors Shanto Iyengar of Stanford University and Sean Westwood of Dartmouth College to design and implement the IAT used in this experiment.
