 The advocate of PI can argue that past ‘best theories’ also raised and met the standards of empirical success, which inductively supports the conclusion that current best theories will be superseded by others which will meet even higher standards of success. Doppelt’s reply is that this new version of PI “should not be given a free pass as though it were on a par with the original pessimistic induction” the reason being that “in the history of the sciences, there is greater continuity in standards of empirical success than in the theories taken to realize them”. Hence, the standards of empirical success change slower than theories. Hence, it is not very likely that current standards of empirical success will change any time soon.
