Steve:
Next time you hear someone say "paradigm" or (especially) "paradigm shift" ask them what they mean. There's a one hundred percent likelihood that they won't have a clue.

On the basis of the above statement, either you don't know the meaning, or the probability is not 100%.
Were you deliberately setting up a paradox? Or were you 'literally' commenting on its use when spoken, rather than when in print?

A similar claim can be made for the expressions 'quantum shift' and 'quantum leap'.
