    Definition: The theory that explains cannot be tested

    Examples:

    Proof:

    The theory advanced to explain why some phenomenon occurs cannot be tested. We test a theory by means of its predictions. For example, a theory may predict that light bends under certain conditions, or that a liquid will change colour if sprayed with acid, or that a psychotic person will respond badly to particular stimuli. If the predicted event fails to occur, then this is evidence against the theory. A theory cannot be tested when it makes no predictions. It is also untestable when it predicts events which would occur whether or not the theory were true.

    Identify the theory. Show that it makes no predictions, or that the predictions it does make cannot ever be wrong, even if the theory is false. Cedarblom and Paulsen: 161
