As the granddaughter of three Holocaust survivors, I was acutely aware of the dark side of human nature. Research shows us that there’s a direct path from contempt for others to dehumanization, and then ultimately, violence. Around 2015, I noticed that these ugly trends were becoming more widespread across Western democracies. I started to think that the principles of moral psychology could play a powerful role in helping us live alongside people with differing backgrounds, beliefs, and values.
