I’m a member of several groups on polymathy and on harnessing talent in multiple areas (it’s something I’m interested in myself, after all). One of the more interesting things I’ve noticed is that when asked about their MBTI types:

1. Everyone knows them already.

2. Almost everyone is an INTJ. Next common is INTP, then ENTP.

3. Most historical polymaths are thought to be INFJs. (What happened to cause the shift? Did thinking types suddenly become more in-tune with their artistic sides recently, or was there something cultural to it?)

How much faith one can put in MBTI types is questionable, but it does support my hypothesis that nonlinear intuitive thought, not straight logic, is required to see the connections between disciplines.
