" It isn't long as is, but it really has the content of a Kindle Single. That content seems legit, with all of the "delusions" he cites having some example from popular business literature. They get a little banal after the first one though; if you've ever read an Internet comment thread you're probably familiar with delusion number two - correlation is not causation. The author also has an irritating habit of explaining the conclusions of faulty research, but not of the (few) examples of valid research he uses as counterpoints. Maybe it's a test to see if I'm interested enough in something that could increase performance by 10% to even look up the citation. "
