I have seen Hooked placed next to Brainfluence by Roger Dooley under neuromarketing books and I can tell you now that these books are not on the same planet. Brainfluence is a far better book: I have listened to the audiobook twice and I later bought the hard copy whereas I won't be listening to hooked again nor will I even get the paperback.
Hooked is not a bad book, it just didn't add much to my knowledge database.
This book was okay but it wasn't actually that memorable.
I would say Contagious - Why Things Catch On by Jonah Berger is a much more enjoyable read and a much better framework for thinking about how to make products addictive.

Time allowing, I love to read. If I read anything interesting, I will blog about it here.
