Major Fault Line in Jonathan Haidt's "Moral Foundation Theory" of Human Evolution



Psychologist Jonathan Haidt on politics, morality, and the coddling of the American mind.

Above is an interview of Jonathan Haidt. It’s pretty good on some things like his latest book The Coddling of the American Mind. I think he may be better on this topic than “human nature” and things such as the evolutionary emergence of human morality, values he contends we are hard-wired for and are therefore compelled to express.

The following excerpted statement of his from the interview caught my attention in that it is revealing in terms of my critique of his book, The Righteous Mind. He’s asked to account for the now Trumpian Republican Party. Haidt’s response raises this question: If his moral foundation theory is as powerful and useful as he leads us to believe in his book, how could one election and one president, Trump, in effect debunk it?

JH: “Trump has shifted a lot of things around. The Republican Party is no longer the social conservative party. I believe, in other research I’ve published with Karen Stenner, a political scientist in Australia, Trump is appealing to more authoritarian tendencies. It’s very hard to see how Donald Trump is a conservative. So the psychology that I just described a moment ago [moral foundation theory] no longer quite applies. [Italics mine.] The Republican Party, I don’t know what’s happening to it [shouldn’t his moral foundation theory provide some answers?], but it is bringing in elements that are overtly racist. It is bringing in desires for rapid change, which is not a conservative virtue, generally.”

Haidt hitching his moral foundation theory to evolutionary human nature remains a problem for me. 

Equally unsatisfactory is his claim in his The Righteous Mind that Democrats are less loyal and less patriotic than Republicans just doesn’t hold water. Since Trump’s election who, really, is proving to be the greater patriot, Nancy Pelosi or Mitch McConnell? I’ve gone over these two main points and others here:


and here:


I think a good theory of cultural evolution, one I’m working on, would tell us a lot more about how humans became what we are and why we behave as we do than Haidt’s moral foundation theory.
