As for this book: It’s a pretty useless book, but I can see how it’s appealing. I can’t see how it being unscientific makes it worse than 90% of similar books in the bookstore.

If he claims it’s solid science that’s obviously bad, but I’m sure all the mindfulness and yoga books do too - and all of those are certainly not very scientific.
