But, what I’m saying is that charisma (and personal marketing for that matter) is by its nature a “wide” skill.

I wouldn’t give him an integral to solve but that’s not what a leader is supposed to do either.

I think a major world leader needs more than charisma but it’s one of the first requirements.

All of his 'success' is purely derived from charisma as far as I can tell. He isn't particularly adept at his prior career of real estate business given that he has under-performed in the markets he has participated in, and he had to commit felony fraud to do it. His biggest success is making people believe that he is more successful than he is.

What intellectually rigorous activity would you say he has an aptitude in?

Looking at the wildly hostile media coverage of him post-2015, you’d come away thinking he’s a major charlatan.

Looking at the glowing media coverage of him pre-2015, he seems like a unique business genius.

The truth is probably in between.

Business and marketing aren’t rigorous intellectual activities like math, but they are bloody hard in a different way - even with an inheritance (how many born-rich kids die 100x richer? Almost none). The problems are very fuzzy and open-ended, and frequently don’t even look like a problem.

You can’t consistently solve these problems profitably over many years without some skill.
