How can obedience and carrying out orders lead to horrific acts such as the Holocaust or the genocides in Rwanda, Cambodia, or Bosnia? For the most part, it is a mystery why obeying instructions from an authority can convince people to kill other human beings, sometimes without hesitation and with incredible cruelty.

Combining social and cognitive neuroscience with real-life accounts from genocide perpetrators, this book sheds light on the process through which obedience influences cognition and behavior. Emilie Caspar, a leading expert in the field, translates this neuroscientific approach into a clear, uncomplicated explanation, even for those with no background in psychology or neuroscience. By better understanding humanity’s propensity for direct orders to short-circuit our own independent decision-making, we can edge closer to effective prevention processes.
