The tyranny of moral intuition?

Liberals don’t understand conservative values. And they can’t recognize this failing, because they’re so convinced of their rationality, open-mindedness and enlightenment.

From Willian Saletan’s review of a new book by psychologist Jonathan Haidt.

Haidt’s previous book, The Happiness Hypothesis, was a fantastic introduction to the psychology of behavior and morality. And I think the basic message of the new book rings true. So I am inclined to recommend it.

My impression from the last book: Haidt has a very slight tendency to hyperbole, and it’s a shame he doesn’t distinguish between the weak and strong evidence. He’s a skilful writer and his own research looks clever, and so I think he could fix this without making his books boring.

I’m curious, though. Readers who actually know something about cognitive psychology: what’s Haidt’s street cred?
