There was an opinion piece in the New York Times titled Do You Have to Be a Jerk to Be Great? in which David Brooks cites from a book called "Range" by David Epstein (emphasis added):
In the first place, being monomaniacal may not even be good for your work. Another book on my summer reading list was “Range,” by David Epstein. It’s a powerful argument that generalists perform better than specialists.
The people who achieve excellence tend to have one foot outside their main world. “Compared to other scientists, Nobel laureates are at least 22 times more likely to partake as an amateur actor, dancer, magician or other type of performer,” Epstein writes.
I don't own the book and haven't found any information about how the data was gathered. 22 times sounds unrealistically high and I'm wondering where you'd even get data for normal scientists to compare to nobel laureates.
Is there any evidence for this claim?
