I'm currently a registered Pacific Green, lean left, and on the political compass I'm basically smack dab on top of Bernie Sanders (whom I voted for and donated to in the 2016 primaries). And have never voted Republican. So his observation is about my own "side" more or less.

But I'm totally unsurprised to see this downvoted here only 18 minutes in.

Here's a short article on the paper: https://ricochet.com/76902/archives/conservatives-understand...

The paper itself: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2027266

Here's his TED talk on it: https://www.ted.com/talks/jonathan_haidt_the_moral_roots_of_...

What's funny is if you bring this up (even with sources) to conservatives. They're unsurprisingly unsurprised. But if you bring it up to liberals they often get furious because it goes against their beliefs that they're the more intelligent, more educated "side". Nevermind that believing in only two possible sides is six times dumber than astrology... something "both sides" are about equally guilty of. If nothing else I strongly encourage everyone to watch his TED talk. It's super informative, well delivered, and has a solid message of unity tbh.
