Invisible Mind

Flexible Social Cognition and Dehumanization


In Invisible Mind, Lasana Harris takes a social neuroscience approach to explaining the worst of human behavior. How can a person take part in racially motivated violence and then tenderly cradle a baby or lovingly pet a puppy? Harris argues that our social cognition—the ability to infer the mental states of another agent—is flexible. That is, we can either engage or withhold social cognition. If we withhold social cognition, we dehumanize the other person. Integrating theory from a range of disciplines—social, developmental, and cognitive psychology, evolutionary anthropology, philosophy, economics, and law—with neuroscience data, Harris explores how and why we engage or withhold social cognition. He examines research in these different disciplines and describes biological processes that underlie flexible social cognition, including brain, genetic, hormonal, and physiological mechanisms.

After laying out the philosophical and theoretical terrain, Harris explores examples of social cognitive ability in nonhumans and explains the evolutionary staying power of this trait. He addresses two motives for social cognition—prediction and explanation—and reviews cases of anthropomorphism (extending social cognition to entities without mental states) and dehumanization (withholding it from people with mental states). He discusses the relation of social cognition to the human/nonhuman distinction and to the evolution of sociality. He considers the importance of social context and, finally, he speculates about the implications of flexible social cognition in such arenas for human interaction as athletic competition and international disputes.

“The elegant and adroit fashion with which Lasana Harris deals in the ambiguity of humanness in Invisible Mind is as important as it is timely. With accessible treatment of dense theory and disturbing practice, Harris presents dilemmas that are not just left hanging or presented for effect, rather they are put center in ways that allow us paths to better selves.”
