Abstract
Two different types of updates of information states are distinguished corresponding to two different kinds of incoming information: information about the actual state of domain; and information about changes made to the state of that domain. Gärdenfors [1986] proves a theorem showing that the first kind of update function can have certain intuitively appealing properties only on pain of triviality. Here a similar trivialisation result is proved for the second kind of update function.
This paper is an improved and shortened version of an unpublished manuscript by the first author. The second author sharpened up the main result of that paper by simplifying to the version presented here.
