Psychologist Barry Beyerstein believes that "hope and uncertainty evoke powerful psychological processes that keep all occult and pseudoscientific character readers in business." We are constantly trying "to make sense out of the barrage of disconnected information we face daily" and "we become so good at filling in to make a reasonable scenario out of disjointed input that we sometimes make sense out of nonsense." We will often fill in the blanks and provide a coherent picture of what we hear and see, even though a careful examination of the evidence would reveal that the data is vague, confusing, obscure, inconsistent and even unintelligible.
