Could someone explain why Jonathan Haidt and Daniel Kahneman do not refer to each other in their major works? That’s despite the fact that theirs concepts, subjects of study, and – most importantly -- outcomes with broad ramifications are almost identical. I’m truly perplexed…

I’ve re-read Haidt’s Righteous Mind few times… and Kahneman’s in his Thinking, Fast and Slow only once mentions Haidt.
