Adherents of the 9/11 Truth movement come from diverse social backgrounds. The movement draws adherents from people of diverse political beliefs including liberals, conservatives, and libertarians. The Anti-Defamation League has named Alan Sabrosky as a key figure in anti-Semitic 9/11 conspiracy theories. Among the organizations that actively discuss and promote such theories are Architects & Engineers for 9/11 Truth, a group that focuses on the collapse of the World Trade Center buildings; 9/11 Truth, founded in 2004; Scholars for 9/11 Truth, founded in 2005, and Scholars for 9/11 Truth & Justice, a group that split from Scholars for 9/11 Truth in 2007 and runs the online publication Journal of 9/11 Studies; 9/11 Citizens Watch, which was already formed in 2002; and the Hispanic Victims Group.

They join the movement for different reasons, loosely self-assemble to fill different roles and are united by their shared mistrust in experts and the establishment (government and reputable sources of knowledge), and conspiratorial stance. Through their engagement, they each find their own fulfillment and satisfaction. Together, they contribute to the persistence, resilience and exaggerated claims of acceptance (in general public) of the movement. These three groups are: Hard core: The
