THE KNOWLEDGE GAP

The purpose of this article is to examine research evidence on knowledge gaps and to ask how strong this evidence is, particularly when amount of mass media publicity is taken into account. Many varying characteristics of 58 studies with relevant data are analyzed. Theoretical and methodological differences among the studies are pointed out, and some conclusions drawn about media effects on knowledge disparities and conditions under which knowledge gaps may or may not occur. Some reasons for conflicting results in the literature are explained, and suggestions are made for future research on knowledge differentials.
