The Center for Positive/Empirical Analysis of Political Economy Model Unit and the Waseda Institute of Political Economy (WINPEC) invited Professor Charles Crabtree (Dartmouth College and Tokyo Foundation) to the 3rd Session of the Empirical Political Science Workshop on July 14. Professor Crabtree provided us with an overview on a series of research uncovering how racial discrimination would exist in American society, not only among the political elites but also in the general public. As a new addition to past studies on racial discrimination in America, by using an original, large-scale survey targeting 250,000 people in the US, his team’s research uncovers if people would react differently when s/he received an email on health survey from a white professor or a black professor. Similar to the experiments conducted to the political elites, a similar pattern of discrimination was observed among the US general public. Also, a discriminatory reaction against the black people was confirmed not only in the whites but also in the non-black minority groups. During the question and answer session, there were lively discussions about possible causal mechanisms, ethical issues in conducting experiments on racial discrimination, and the feasibility of similar research in Japan.
