The self-fulfilling prophecy is
A positive or negative prophecy, strongly held belief, or delusion - declared as truth when it is actually false - may sufficiently influence people so that their reactions ultimately fulfill the once-false prophecy. (And of course Morty Lefkoe is helping people to eliminate false beliefs)
, in the beginning, a false definition of the situation evoking a new behaviour which makes the original false conception come 'true'. This specious validity of the self-fulfilling prophecy perpetuates a reign of error. For the prophet will cite the actual course of events as proof that he was right from the very beginning.
Robert King Merton (1910 – 2003) was a distinguished American sociologist. He spent most of his career teaching at Columbia University, where he attained the rank of University Professor. In 1994, Merton won the National Medal of Science for his contributions to the field and for having founded the sociology of science [http://www.columbia.edu/cu/news/03/02/robertKMerton.html].
Merton developed notable concepts such as "unintended consequences(outcomes that are not the ones intended by a purposeful action )", the "reference group", and "role strain" but is perhaps best known for having created the terms "role model" and "self-fulfilling prophecy". A central element of modern sociological, political and economic theory, the "self-fulfilling prophecy" is a process whereby a belief or an expectation, correct or incorrect, affects the outcome of a situation or the way a person or a group will behave. Merton's work on the "role model" first appeared in a study on the socialization of medical students at Columbia. The term grew from his theory of a reference group, or the group to which individuals compare themselves, but to which they do not necessarily belong. Social roles were a central piece of Merton's theory of social groups. Merton emphasized that, rather than a person assuming one role and one status, they have a status set in the social structure that has attached to it a whole set of expected behaviors.
Examples abound in studies of cognitive dissonance theory and the related self-perception theory; people will often change their attitudes to come into line with what they profess publicly.
The phenomenon of the "inevitability of war" is a self-fulfilling prophecy that has received considerable study.
