What we didn't know back in the 1990s was how little this sort of presentation (that you describe) was engaging. Everyone could sort of tell, which is why producers shied away from it, but with the rise of algorithms and internet slop it can be measured very precisely. And the measurements show that it's damn near close to zero, on whatever scale it is that they use.

Intelligent people are boring. They're worried about problem-solving. Problems like on the tests back in school that used to make my head hurt, problems I'd get the red X on and have to repeat 3rd grade over because of. Unintelligent people are exciting. They're in conflict. They're fighting, or going to find a fight somewhere, and if you watch long enough they might even get into that fight right then and there (Bill O'Reilly used to do that on air, after all).
