I disagree. I know quite a few people who are incredibly charismatic, but exceptionally narrow in their cognitive competence. In fact, one of the problems that I would highlight about charisma is that it allows you to be get away with a lot more stupid shit than you would if you had to get by on other talents.

I agree with your point, but I think your examples are charming one-on-onenor in small groups only.

To be considered charming to a large group of people, like half the USA, you need to be conversant in things that are relevant to all of them. A narrow person can never have a wide appeal.
