“"Information" in most, if not all, of its connotations seems to rest upon the notion of selective power. The Shannon theory regards the information source, in emitting the signals (signs), as exerting a selective power upon the ensemble of messages. for example, observes that what people value in a source of information (i. e., what they are prepared to pay for) depends upon its exclusiveness and prediction power; he cites instances of a newspaper editor hoping for a "scoop" and a racegoer receiving information from a tipster. "Exclusiveness" here implies the selecting of that one particular recipient out of the population, while the "prediction" value of information rests upon the power it gives to the recipient to select his future action, out of the whole range of prior uncertainty as to what action to take. Again, signs have the power to select responses in people, such responses depending upon a totality of conditions. Human communication channels consist of individuals in conversation, or in various forms of social intercourse. Each individual and each conversation is unique; different people react to signs in different ways, depending each upon their own past experiences and upon the environment at the time. It is such variations, such differences, which gives rise to the principal problems in the study of human communication.”
