Lippmann–Dewey Debate
The Lippmann–Dewey Debate is a term applied in the late 20th century to a virtual debate between Walter Lippmann and John Dewey over the nature and viability of democracy and the role of the media in a world that was becoming more and more complicated. Lippmann was worried that within democracies public opinion based on citizens' mental constructs, termed pseudo-environments was moulded by the media and a range of stereotypes, and that this made the public poor arbiters of good decision making.
