The works of Carr and his influence among conspiracy theorists has been studied by the American historian Daniel Pipes (1997) and the folklorist Bill Ellis (2000). The French philosopher and historian Pierre-André Taguieff recently wrote "La Foire aux illuminés: Ésotérisme, théorie du complot, extrémisme" (2005) (The Illuminati fair: esotericism, plot theory, extremism) where he makes an analysis of "Pawns in the Game". He shows that Carr belongs to a tradition of conspiracy theorists that goes far back to Augustin Barruel and is represented by the "Protocols of the Elders of Zion", which frequently quoted in Carr's work, in the 20th century. Taguieff also studied Carr's theories in "L'imaginaire du complot mondial: Aspects d'un mythe moderne" (The world plot imaginary: about a modern myth), 2006.
