 A second problem is that the strategy does not seem to properly discriminate cognitive content from other sorts of information a subject’s body may carry. A baby is better adapted to worlds in which extreme heat can damage its body than to worlds in which it cannot. When the baby touches something hot it automatically jerks away. This action has a useful purpose in a world in which heat is damaging, but would be pointless in a world in which it was not. But it does not follow that the baby believes that extreme heat is damaging. (See Stalnaker 1989, White 1991.)
