Population: challenging world crisis, 1969 (02-07-2015)

was an American behavioral scientist, known for work on communication and mass media. He was a leading proponent of the broad idea of the "behavioral sciences", a field he saw as including areas such as public opinion. In Chapter 14 of Voting (1954), he enunciated what has become known as Berelson's paradox on democracy: while classical theories of its success assume voters committed to interest in public life, this fails to correspond with practical politics, while the system itself functions.
