You is smart

Yes. I dispute the phrasing- it would be more correct to say that Ben Carson is not terribly intelligent. He has an aptitude and an area of expertise. In the technical sense, intelligence isn’t so much how “smart” or skilled you are, it’s more a measure of adaptability. Your ability to assimilate information and make determinations on subjects without a full set of information- or in absenceof specific information.

A good way to think of it is that almost any person could, if dedicated and motivated, memorize most known laws of physics and memorize mathematics and formulas etc. this person, with the memorized information, could solve many complex problems and perhaps make some new discoveries. But knowing how gravitational lensing will act on a photo from a space telescope because you memorized the relevant information, or have experience, is not the same as someone who’s never had experience or read on the subject figuring out there is a phenomenon at work and what that is.

Being skilled at a thing or being knowledgeable on any subject is not an inherent measure of intelligence. Even understanding how these things relate or can be applied elsewhere isn’t- if that knowledge comes from experience or observation. It’s an entirely different thing to watch a YouTube tutorial on how to tie a knot, or to have worked with knots a long time and understand rope, than it is to figure out how to tie a certain knot- and/or the need for it, from square one.
