wow, this guy made it to TED? I saw him give this talk at penn, where he argued that we should never "maximize" (spend a lot of time researching) any decision, even seemingly important ones. The example he gave was a professional tennis player who, contrary to popular opinion, shouldn't "maximize" on a tennis racket because the psychological burden of doing all that research outweighed the marginal gain you'd get from buying a super-racket instead of some normal good racket. I also remember he was very unconvincing because that line of reasoning often leads to bad decisions (and rejecting it is what hacking's all about).
