Basically none of the books upper thread talks about was written by an actual scientist trained in the area they write about. They were written by popular people, either not scientists or writing outside of their expertise.
I'll give you one concrete example: "Presence: Bringing Your Boldest Self to Your Biggest Challenges", by Amy Cuddy. That book was based on the (now completely falsified) theory of "Power posing"[0], which the author published peer-reviewed papers on.
It's a neat little grift: publish a couple of papers, get yourself a TED talk, sign a book deal, and suddenly you're getting hired to teach leadership courses to clueless MBAs and give conference talks to bored executives.
