One of my favourite science writers—the editor at large of Seed Magazine, Jonah Lehrer—has been interviewed by The Commonwealth Club about his forthcoming book, The Decisive Moment/How We Decide (UK/US titles, respectively).
The video of the interview is full of excellent anecdotes (backed-up by peer reviewed research) on many topics ranging from emotional and rational decision making to the tip-of-the-tongue effect and the placebo effect.
(For those of you who attended Ignite Cardiff last night, Lehrer discusses a study very similar to one I discussed in my talk that you may find interesting.)
