 In psychology, the view that memory is factive has been much less common. This is not very surprising, given that much psychological research on remembering focuses on unsuccessful remembering: understanding how unsuccessful remembering occurs provides important insights into the mechanisms responsible for successful remembering, just as understanding how perceptual illusions and hallucinations occur provides important insights into the mechanisms response for successful perception. What is more surprising is that psychologists have sometimes gone too far in the opposite direction, assuming that, because remembering is constructive, it is bound to be false (Ost &amp; Costall 2002). This is in effect to treat memory as counterfactive. The distinction between authenticity and truth enables us to see that constructive, generative remembering need not be characterized by falsity. The generative character of remembering does, however, point to the need for a more sophisticated criterion of truth (S. Campbell 2014). While the fact that remembering is generative does not imply that memories are bound to be outright false, it does suggest that they are frequently false in some respects. This, in turn, suggests that remembering need not be fully accurate in order to be fully adequate, thus pointing towards a need for a criterion that acknowledges that truth in memory comes in degrees.
