 The understanding of information as range has its origins in Bar-Hillel and Carnap’s theory of semantic information, Bar-Hillel and Carnap (1952). It is here that the inverse range principle is given its first articulation with regard to the informational content of a proposition. The inverse range principle states that there is an inverse relationship between the information contained by a proposition on the one hand, and the likelihood of that proposition being true on the other. That is, the more information carried by a proposition, the less likely it is that the proposition is true. Similarly, the more likely the truth of a proposition, the less information it carries.
