This chapter takes a look at what happens when informational environments happen to change or are actively changed. There are two apparent reasons why Godfrey-Smith does not consider the possibility of an analogy of functions between natural information and purposefully produced signals. First, his concept of cognition is explicitly restricted to a pragmatic interpretation in the Deweyan tradition, where it figures as a problem-solving capacity possessed by individuals in the first place. Second, in Godfrey-Smith's terms, cognitive tasks, may be delegated to the environment by means of informational artefacts that still remain constituents of cognition proper. The paradigm of changes in the informational environments of human beings will be the introduction of technologies that alter the way in which information that is relevant to their activities is available to them, so as to alter the way in which they collect and act upon that information.
