Haidt is a social psychologist whose research on morality across cultures led up to his much-quoted 2008 TED talk on the psychological roots of the American culture war. He asks, "Can't we all disagree more constructively?" In September 2009, Jonathan Haidt spoke to the TED Blog about the moral psychology behind the healthcare debate in the United States.
He's also active in the study of positive psychology and human flourishing.
At TED2012 he’s combining his work on morality with his work on happiness to talk about “hive psychology” – the ability that humans have to lose themselves in groups pursuing larger projects, almost like bees in a hive. This hivish ability Is crucial, he argues, for understanding the origins of morality, politics, and religion. These are ideas that Haidt develops at greater length in his new book, The Righteous Mind: Why Good People are Divided by Politics and Religion.
