Is There a Correlation Between Cognitive and Artistic Talent in Great Minds?

[selfAdjoint]

The usual expectation, based on the hypothesis that artistic talent is independent of cognitive talent would be that the great man's efforts would be close to average. But in fact great men had have more than average talents in the arts. Einstein was a bit better than a putzer at the violin, and delighted to play duets and quartets. Feynmann, in addition to his famous bongo efforts, was fairly skilled at an artist, doing fair portraits (which ain't easy).

So I think there is a connection between cognitive talent and artistic talent.
