This is a good line: "It found that smarter entities are subjectively judged to behave less coherently"
I think this is twofold:
1. Advanced intelligence requires the ability to traverse between domain valleys in the cognitive manifold. Be it via temperature or some fancy tunneling technique, it's going to be higher error (less coherent) in the valleys of the manifold than naive gradient following to the local minima.
2. It's hard to "punch up" when evaluating intelligence. When someone is a certain amount smarter than you, distinguishing their plausible bullshit from their deep insights is really, really hard.
What do 'domain valleys' and 'tunneling' mean in this context?

Insights are “deep” not on their own merit, but because they reveal something profound about reality. Such a revelation is either testable or not. If it’s testable, distinguishing it from bullshit is relatively easy, and if it’s not testable even in principle, a good heuristic is to put it in the bullshit category by default.
Incoherence is not error.
You can have a vanishingly small error and an incoherence at its max.
That would be evidence of perfect alignment (zero bias) and very low variance.
