I think we need to be very careful before adopting this term. Contradiction (in English) means 180°ree; opposition, not merely a small variation or *some* assertion true for B which is false for A: it means *all* assertions which were true for B are false for A. Perhaps "colliding" or "conflicting" PSIs would be closer? ///Peter
