I've just finished reading Predictably Irrational by Dan Ariely.
I think most LWers would enjoy it. If you've read the sequences, you probably won't learn that many new things (though I did learn a few), but it's a good way to refresh your memory (and it probably helps memorization to see those biases approached from a different angle).
It's a bit light compared to going straight to the studies, but it's also a quick read.
Good to give as gift to friends.
We've had these for a year, I'm sure we all know what to do by now.
