In this book, I summarize more than 30 years of research on factors that can create a "perfect storm" which leads good people to engage in evil actions. This transformation of human character is what I call the "Lucifer Effect," named after God's favorite angel, Lucifer, who fell from grace and ultimately became Satan.

As part of this account, The Lucifer Effect tells, for the first time, the full story behind the Stanford Prison Experiment, a now-classic study I conducted in 1971.

How and why did this transformation take place, and what does it tell us about recent events such as the Abu Ghraib prisoner abuses in Iraq? Equally important, what does it say about the "nature of human nature," and what does it suggest about effective ways to prevent such abuses in the future?


Dehumanization is one of the central processes in the transformation of ordinary, normal people into indifferent or even wanton perpetrators of evil. Dehumanization is like a “cortical cataract” that clouds one’s thinking and fosters the perception that other people are less than human. It makes some people come to see those others as enemies deserving of torment, torture, and even annihilation.
