What is race? A common view among humanists and social scientists is that race is “social” or is a “social construction.” If so, how is it constructed? My work explores what it means to say that race is socially constructed, and looks at psychological proclivities (e.g. like proclivities towards essentializing race, or unconscious biases) that may play a role in such construction. Recently, I have also begun to characterize the general features of structures by which racial inequality accumulates over generations.
