I think we need to be very careful before adopting this term.
Contradiction (in English) means 180&degree; 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?
