It’s actually part of my point.

Doctors are intelligent, you have to be to absorb the amount of information they are required to learn. However, it’s specialised intelligence. Being smart about medicine doesn’t make you smart about other things.

It’s like we all have a pool of base intelligence. We can then pour it into various moulds. The traditional intelligent professions are often just reliant on a large amount of specialised intelligence. This actually robs them other other forms.

It’s easy, when you can demonstrate high intelligence, in a difficult field, to assume you are intelligent across the board. A stupid person can often know they are stupid and so can compensate. An “intelligent” person can be blindsided by their weaknesses.
