That's difference in knowledge vs intelligence though. We see repeatedly that people with expert knowledge are frequently wrong because they shape what they see to fit their knowledge. Intelligent people can give more insight on a variety of topics without having expert level knowledge just because they are smart and can put the puzzle together differently.

It's the adage of "when you only have a hammer everything looks like a nail."

Intelligent people have a full toolbox to analyze things with but domain experts tend to only have increasingly large hammers.
