I really enjoyed the book, but I think it could benefit from being longer. There was so much to explore in the book, I felt some parts were kinda rushed. I especially would have liked if Ruby and Grace's relationship had been more developed.
I also wished she talked more about the psychology implications because, well, that is the title of the book and it's awesome. But I guess most people wouldn't really be interested in reading fake science. I, however, was hoping we'd get some fake article together with the questionnaires, I'd totally read it with an excitment never found when I'm reading actual scientific papers lol
