emotional funny informative lighthearted medium-paced

Informative, interesting. Fallon has a bad habit of starting a chapter with interesting anecdote-style information, then killing his momentum with 5-10 pages of deep neuro stuff. I wish that aspect could have been delivered a little more smoothly. 
What to say about this book? Fallon’s unapologetic genetic determinism was grating a bit - he seems like a late holdover from the 90s to early 2000s brain craze. Well, we’re a couple decades out and that didn’t quite pan. On the other hand, I found his three-legged stool theory prescient. Overall, I think his callous attitude to others and his disdain for women really did take away from how much I liked this book. I also think he sort of masked just how many people had issues with him or what those issues were until the end. It was a well-written book and I admire his honesty. I did learn plenty about psychopathy. I guess he self-describes as a blowhard, so it shouldn’t be too rude to say it here, but I think generally scientists should not be quite so cocksure about unproven hypotheses.
