"Do chimps understand what Jon Stewart (or another chimp) believes?" That's the title of a post from Dave Munger, who, pointing out that Stewart brings up the subject, uses the opportunity to ask to what extent chimpanzees possess object permanence, and more importantly, whether they can attribute thoughts to other chimps and make inferences when it comes to competition for a tasty treat. A cleverly constructed experiment suggests they can, though less well than a six year old human.
