Echoes of a Conspiracy: Birthers, Truthers, and the Cultivation of Extremism

Pages 1-17 | Published online: 05 Feb 2014
 

Abstract

A significant number of Americans express sympathies for conspiracy theories about Barack Obama's birth and George Bush's role in the 9/11 attacks. This study sought to test the role of ideological media in perpetuating these beliefs. Specifically, experiments were conducted to determine if ideologically homogeneous media echo-chambers could cultivate belief in conspiracy theories and whether debunking information would reverse this belief. Results found that media echo-chambers increased belief in conspiracy theories though debunking information reversed or minimized this effect. Results confirm the role of ideological media in spreading extremist attitudes but also demonstrate the value of debunking efforts.
