In order to better understand why racism still exists, it helps to study it like a science. Keon West, social psychologist at Goldsmiths at the University of London, joins host Krys Boyd to discuss his rigorous research into racist beliefs, the results of social experiments that show how far we’ve moved the mark since the Civil Rights era and what we can definitively say about prejudice today. His book is “The Science of Racism: Everything You Need to Know but Probably Don’t—Yet.”
