Tichenor, P. J.

Tichenor, P. J. is a scholar known for his work in communication studies, particularly regarding the ways media affects public understanding and opinion. He proposed the "knowledge gap" hypothesis, which suggests that as information becomes more available, those who are already knowledgeable tend to acquire more knowledge at a faster rate than those with less prior knowledge. This can lead to widening gaps in understanding between different social groups. His research highlights the importance of accessibility to information and its impact on societal equity and informed citizenship.
