"Conservatism in human beings may be characterized as behavior by individuals who possess a reluctance to update their beliefs in the face of new information. This property is a natural result from information theory. . . the information one can receive is information sent minus equivocation, which is reduced gradually as the receiver’s background knowledge about the source increases. Hence, conservatism reflects the gradual reduction of equivocation by the receiver of any given information." (Jing Chen, The Entropy Theory of Human Mind, http://web.unbc.ca/~chenj/1.pdf).
