    "abstract": "We illustrate two simple spin examples which show that in the consistent\nhistories approach to quantum mechanics one can retrodict with certainty\nincompatible or contradictory propositions corresponding to non-orthogonal or,\nrespectively, orthogonal projections. V.2 vs. V1: The example previously quoted\nas \"d\u0027Espagnat\u0027s example\" is now properly quoted as \"Griffiths\u0027 example\". A\nreference to a previous work by Aharonov and Vaidman is added.",
