Hate is among the most powerful of human emotions - it has caused great sorrow and suffering - and yet it has been understudied by psychologists. The Psychology of Hate is a groundbreaking book that brings together experts on the psychology of hate to present their diverse viewpoints in a single volume. The contributors address a set of questions that include: How do you conceptualize hate and what evidence is there for this conceptualization? What do you see as the role of hate in terrorism, massacres, and genocides? How can hate be assessed? The volume additionally provides concrete suggestions for how to combat hate, and attempts to understand the minds both of those who hate and those who are hated.
