I was thinking about this and it came to me that all of this "thinkers", "creators", "inventors" generally are pretty out there personality-wise, and the hand down their ideas to the people in the trenches (the therapists, the teachers, the engineers, etc.) to work out the kinks, make their ideas actually practical and workable, modify their errors, etc. It may take a great deal of eccentricity to come up with this stuff, and it takes others to modify that eccentricity into something that might come of practical use.
