The Volokh Conspiracy's Tyler Cowen links to this fascinating article about an old psychiatric experiment where a group of perfectly sane people feigned a symptom and submitted themselves for psychiatric diagnosis, and an individual who tried the experiment anew. Interesting stuff. It stands out to me because Dershowitz referred to it tangentially in his talk - I forget the exact context. (Obscure movie reference: "Say you're thinking about a plate of shrimp. Suddenly someone says plate, or shrimp, or plate of shrimp. Out of the blue. No explanation. No use looking for one either. It's all part of the cosmic unconsciousness.")

Anyway, interesting stuff (in The Guardian!).
