>Epstein's book is called "Range: _Why_ Generalists Triumph in a Specialized World", not "Range: How

It looks like the blog author remembered the older title that had the word "How" but linked the url for the newer title that changed it to "Why". Previous title with "_How_" : https://www.amazon.com/Range-Generalists-Triumph-Specialized...

interesting - runs contrary (to the most part) - of The Range which I read recently (https://amzn.to/3dCTqcE). There is something to be said on focussing though, to easy to get distracted.
