Before revision: In one study, for example, subjects reported higher confidence in a prediction of the final grade point average of a student after seeing a first-year record of consistent B apos;s than a first-year record of an even number of A apos;s and C apos;s. Consistent patterns may be observed when input variables are highly redundant or correlated, which may increase subjective confidence.
