I always found it odd that people who are intelligent enough to work in IQ-loaded fields are as easily manipulated by either rhetoric or ideology as anyone else.
growing up I always assumed that everyone would grasp some aspect of game theory intuitively, I still remember the day I found out game theory was a thing - it was like finding out that someone successfully systematized common sense.
most people take the things people say as if they were worth considering. signals without cost are only useful as knowledge of what the signaler wants fools to believe.
The world is not full of idiots, rather communication channels are heavily managed to prevent people from establishing consensus around the obvious.
No matter how many people think press release X is obviously wrong - 80%, 95, 99% - it'll always be "the comments section criticizing the article," or "bloggers sharing incisive criticism."
A lot (a lot) of people intuitively understand something, but throw it out because it doesn't align with how they want (or need) things to be.
It seems even otherwise intelligent people will cultivate as much ignorance as possible to try and bend reality.
I assume it is easier to manipulate someone who lives in symbols than someone who lives in dirt.

Game Theory as a field is actually very complex and often reveals dominant strategies that would never occur to someone as the "common sense" approach to a problem. It was arguably created to solve for problems where there was no obvious correct answer, even for a very intelligent person.
