Ahhhh, this issue again. Intelligence can be measure in so many ways. It is what we do with that intelligence that counts.
In places that I "excel", I can say that I am above average intelligence.
In places that I think I am mediocre, I'll say that I have average intelligence.
In places that I don't know much at all, I'll say that I am learning.
Even if I am average or above average intelligence in one area, I am still learning.
I don't confine myself to a 1 point measuring system. But when someone believes that I'm intelligent, I like to think that I still have much to learn. If someone calls me wise, I would like to think I still have much to learn. The answer being is that I am not a doctor, I am not a mechanic, I am not a construction worker, I am not a biologist, I am not a [insert the endless title given to workers.]
The doctor has more experience than me in his field, therefore, the doctor has above average intelligence in that area. However, I can't say the same thing if I compared the doctor to me in another area.
