This was a bit of a mindblower. I'm always open to some counterintuitive conclusions, assuming the premises are reasonable and the logic is sturdy. And Kahneman's book is full of such ideas. But what was continually surprising was how much sense these revelations made. It's useful, though, to have labels to apply to them—confirmation bias, availability bias, the halo effect, etc. As the author himself points out, it's not necessarily going to change the way you act day-to-day. But it does at least give you a bit of insight and understanding, which I think gradually has some effect. And even if it doesn't, insight and understanding are worthwhile goals all on their own.
