A Formal Summary of The Knowledge Gap Hypothesis
Given the preceding information, the knowledge gap hypothesis can be expressed using the following set of related propositions:
- People in a society exhibit great psychological diversity due to their psychological makeup, learned experiences, social relationships, and social category memberships.
- Despite these differences, people with more education tend to have better developed cognitive and communication skills, broader social spheres with more and more diverse social contacts, and a greater amount of stored information than their counterparts with less education.
- People with greater education also tend express interest in, and expose themselves to, a broader range of topics, including serious topics like public affairs, science, and health news.
- Therefore, as the infusion of mass media information into a social system increases, segments of the population with higher socioeconomic status tend to acquire this information at a faster rate than the lower status segments so that the gap in knowledge between these segments tends to increase rather than decrease.

Famous quotes containing the words formal, summary, knowledge, gap and/or hypothesis:
“It is in the nature of allegory, as opposed to symbolism, to beg the question of absolute reality. The allegorist avails himself of a formal correspondence between “ideas” and “things,” both of which he assumes as given; he need not inquire whether either sphere is “real” or whether, in the final analysis, reality consists in their interaction.”
—Charles, Jr. Feidelson, U.S. educator, critic. Symbolism and American Literature, ch. 1, University of Chicago Press (1953)
“Product of a myriad various minds and contending tongues, compact of obscure and minute association, a language has its own abundant and often recondite laws, in the habitual and summary recognition of which scholarship consists.”
—Walter Pater (1839–1894)
“... business training in early life should not be regarded solely as insurance against destitution in the case of an emergency. For from business experience women can gain, too, knowledge of the world and of human beings, which should be of immeasurable value to their marriage careers. Self-discipline, co-operation, adaptability, efficiency, economic management,—if she learns these in her business life she is liable for many less heartbreaks and disappointments in her married life.”
—Hortense Odlum (1892–?)
“The gap between the committed and the indifferent is a Sahara whose faint trails, followed by the mind’s eye only, fade out in sand.”
—Nadine Gordimer (b. 1923)
“It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.”
—Konrad Lorenz (1903–1989)
