I was first exposed to this idea in a book called Greatness: Who makes history and why. IIRC, one of the points was that most famous generals (at least historically) did not typically have extremely high IQs (e.g., 150+) -- the generals needed to be in the 11x-12x range so that they could be within an IQ range that was able to empathize with their soldiers (or at least the junior officers) who were likely in the 9x-10x range. I just checked the ToC on Amazon, and I think chapter 8 touches on this topic. It has been a while since I read it, so I might be wrong. I can't recall what sources the author cited, if any. On a personal level, the idea of a "window of comprehension" has helped me a lot. I used to get frustrated as a kid when people didn't see the same solutions (or even problems) that I saw. Later I came to realize that they were just seeing it from a different perspective than I was. There can be some complex social interaction to get other folks to see the bigger and more dynamic problem and solution space without coming across as condescending, but it's awesome when it happens.
