That's Disgusting

Disgust originated to prevent us from eating poisonous food but this safety mechanism has evolved into a uniquely human emotion that dictates how we treat others, shapes our cultural norms and even has implications for our health. That's Disgusting illuminates the science behind disgust, tackling such colourful topics as cannibalism, humour and pornography to address the larger questions of why sources of disgust vary among people and societies, where disgust comes from in our brain and what deeper fears it reflects. The book explores how disgust influences our personalities, our lives and our values. It turns out that disgust underlies more than we realise, from political ideologies to the lure of horror movies. Drawing on research in psychology and evolutionary biology, That's Disgusting shows us that disgust mirrors human nature and is as complex and varied as we are.
