Generic Conspiracist Beliefs Scale

The Generic Conspiracist Beliefs Scale (Brotherton, French & Pickering, 2013) measures the general tendency to believe in conspiracy theories without naming any particular one. 15 statements about governments, elites, science and information; rate how likely each is to be true on a 5-point scale. The total score is the intended measure; the five 3-item facets are shown for interest. Percentiles are from the scale's validation sample of 235 UK university students (78% female, mean age 25), so they describe a young, mildly skeptical population rather than the general public.
