English fascists and communists both took the F Scale in one 1953 study

Evidence

Coulter (1953) administered the F Scale to forty-three English Fascists, also to fortythree English Communists, and also to eighty-three English soldiers who did not belong to either political extreme. All subjects are said to have been of the working class. Coulter’s research was done under the direction of H.J.Eysenck of London’s Maudsley Hospital and we will, a little further on, discuss the several results of this study in connection with Eysenck’s theory of the organization of attitudes. — John T.
