Prophets of Deceit: A Study of the Techniques of the American Agitator is a sociological and psychological study published in 1949 by Leo Löwenthal and Norbert Guterman. The work was produced as part of the "Studies in Prejudice" series, a research initiative sponsored by the American Jewish Committee that also included the influential study The Authoritarian Personality.
The book provides a systematic content analysis of the rhetoric and psychological techniques utilized by American agitators and demagogues during the 1930s and 1940s. Löwenthal and Guterman, associated with the Frankfurt School of critical theory, examined a vast quantity of speeches, pamphlets, and radio broadcasts to identify recurring patterns in anti-democratic and fascist-leaning propaganda.
Key aspects of the study include:
- The Agitator vs. The Reformer: The authors distinguish the "agitator" from the political reformer or revolutionary. While the reformer addresses specific social or economic grievances with proposed programs, the agitator focuses on psychological manipulation. According to the study, the agitator does not seek to solve objective problems but rather to redirect social discontent toward perceived enemies and "scapegoats."
- The "Enemy" Archetype: A central theme of the work is the agitator's reliance on creating an "out-group" or "enemy." This enemy is often depicted as simultaneously subhuman and omnipotent, posing an existential threat to the audience’s way of life.
- Psychological Appeal: Drawing on psychoanalytic theory, the authors argue that the agitator provides followers with a sense of belonging and superiority. By identifying with the leader, the follower compensates for personal feelings of powerlessness and social alienation.
- Rhetorical Tropes: The study identifies specific tropes, such as the "charlatan" persona, the "simple truth" versus the "corrupt elite," and the promise of a return to a perceived lost golden age.
Prophets of Deceit remains a foundational text in the fields of social psychology and communications, particularly regarding the analysis of demagoguery and the mechanisms of political radicalization.
