That’s a false dichotomy. Being a president is tangentially related to exceptional intelligence.
A better example would be Brian May (of Queen). No correlation between academic credentials and artistic career. There, if the article were about black holes and May had an opinion, I would expect the reporter to cite his PhD, making it a (potentially) informed opinion.
The people who have top YouTube channels also have exceptional intelligence. Maybe less so in logical intelligence or rote memorization, but more so in other intelligences.

I am not sure why that example is better -- Muller's academic credentials are very well related to his career. As were Wilson's.
