In the comments on our profile of Bueno de Mesquita and his surprisingly accurate prediction models, some readers (here, for example) are wondering how this kind of prediction might affect free will.

The problem of free will has been around for a while. Free will isn't just threatened by de Mesquita's rational choice theory. Before de Mesquita, people were worried about free will and God's omniscience. Now some think free will is incompatible with the laws of physics themselves.

Anyway, this primer from Waking Life is surprisingly comprehensive.
