Race Differences in Ethnocentrism with Edward Dutton

What can scientific research tell us about why some peoples are more open to immigrants than others? Why do some nations put up walls where others put up welcome signs, and what possible outcomes can be expected from both of these responses? Edward Dutton has delved deeply into these and related topics in his book Race Differences in Ethnocentrism. He joins Interregnum to discuss his work and the surprising conclusions he has drawn on one of the most pressing questions confronting European peoples today.
