Philip E. Converse

Philip E. Converse

Director: 1989–94

A political scientist with degrees in English, sociology, and social psychology, Philip E. Converse was a CASBS fellow in 1979–80. The American Voter, a book he coauthored in 1960, is considered a groundbreaking work in shaping how we view political behavior: one of its primary, and controversial, themes was the assertion that most voters do not think in a sophisticated way about voting.

In this and other studies, he concluded that most American voters profess no clear ideology. And most voters don’t seek much information about an issue unless they believe it has a clear and immediate impact on their own lives. 

Converse was born in Concord, New Hampshire, and earned his PhD from the University of Michigan, where he was later a professor. He was a fellow of the American Academy of Arts and Sciences, the National Academy of Sciences, and the American Philosophical Society.
