How 9/11 Fueled the Rise of Mainstream Conspiracy Theories in America

The September 11, 2001 attacks marked a turning point in how conspiracy theories spread and gained public traction in the United States. Before 9/11, fringe theories were largely confined to obscure channels like shortwave radio, reaching only limited audiences. The scale and shock of the attacks created widespread public distrust, providing fertile ground for alternative narratives to flourish. Figures like Alex Jones rose to prominence in this environment, bringing conspiracy thinking into the mainstream media landscape. The post-9/11 era is now widely seen as the beginning of a broader cultural shift toward conspiratorial thinking in American public life.
