In Mark Manson's new book[0] he talks about how humans can excel at very few things, often barely one, and that "being a good person" for lack of a better phrase counts as one. It seems obvious in hindsight, but struck me because I hadn't thought of it that way before.

(The book is incredible, by the way. I've already read it twice, just like Derek Sivers. Recommend it highly.)

I haven't read the book, but this doesn't seem to fit with what's known about general intelligence, nor the examples of polymaths from the renaissance period.

I suspect the causes are societal, from the constraints placed on our time and freedom to explore and become well rounded.
