There‘s not a lot here. Brown does a nice job of bringing in a lot of studies but I don‘t consider myself well-versed on the topic and I had heard of most of them. And I think she should have spent more time on the how and what, not the why (though I have this beef with most books of this kind - I picked the book up, I‘m already sold on the concept…)
It did make me want to pick up some of her fiction, though!
