Interestingly, the authors continues to warn about too easy correlations and the misuse about statistics. Unfortunately, they also continues to glorify themselves, to the point where it gets irritating.

They also tries to reflect some of the criticism about their research for the previous book, but that was expected and doesn't impede the readability of the book (even though you need to have read the previous book of course, to understand some of their references).

But the book blows up in the last, opiniated, non-researched, and out of context, chapter. The respect for the authors are so much diminished, so you question if they have in fact written it!

Still, with the exception of the self-glorification and the last chapter, the book is still worth reading, but it doesn't give you any more insight than the previous book.
