Why do people commit hate crimes? A world-leading criminologist explores the tipping point between prejudice and hate crime, analysing human behaviour across the globe and throughout history in this vital book. Drawing on twenty years of pioneering research as well as his own experience as a hate-crime victim, world-renowned criminologist Matthew Williams explores one of the most pressing issues of our age: with hate crimes at an all-time high, what motivates people to commit them and what can we do to help turn the tide? Surveying human behaviour across the globe and reaching back through time, from our tribal ancestors in prehistory to artificial intelligence in the twenty-first century, The Science of Hate is a groundbreaking and surprising examination of the elusive 'tipping point' between prejudice and hate.
