We all have ten types of human in our head.

They're the people we become when we face life's most difficult decisions. We want to believe there are things we would always do - or things we never would. But how can we be sure? What are our limits? Do we have limits?

The Ten Types of Human is a pioneering examination of human nature. It looks at the best and worst that human beings are capable of, and asks why. It explores the frontiers of the human experience, uncovering the forces that shape our thoughts and actions in extreme situations.

From courtrooms to civil wars, from Columbus to child soldiers, Dexter Dias takes us on a globe-spanning journey in search of answers, touching on the lives of some truly exceptional people.

Combining cutting-edge neuroscience, social psychology and human rights research, The Ten Types of Human is a provocative map to our hidden selves. It provides a new understanding of who we are - and who we can be.
