This was organized in a very similar way to the other Malcolm Gladwell book I read (Talking to Strangers): here's an idea! But no! But yes! It was thoroughly entertaining to listen to, but I don't agree with everything presented. And in fact, this one seems to directly contradict Talking to Strangers: Blink says you can tell everything you need to know by the look on someone's face, but Talking to Strangers says you can't tell what someone is thinking at all based on their face. That's the problem with simplifying and distilling psychological and other scientific studies down, I guess.
Still, it did present some interesting ideas and takeaways. Like how studying and training about a subject can help form our gut reactions about that subject, so that we're not as influenced by implicit bias or other unknown prejudices. This gut feeling should trusted when one is an expert with a lot of experience in an area, but just can't shake the bad "gut feeling": the fire fighter who orders his men out of the room and the floor collapses a second later; the art expert who intuits that the statute is a fake despite the scientific tests. Of course, when one doesn't have a lot of experience or is trained wrong, trusting one's instincts can be disastrous: the cops who shoot a man because a wallet looks like a gun. There are every day snap judgments that can be good or bad, but we have the ability to train them if we surround ourselves by the right inputs.
