I thought that I knew what 'paradigm' and 'paradigm shift' meant but after Steve's assertion that nobody knows, I looked them up in the dictionary. It turns out that I do know what they mean, although there is a second definition for 'paradigm', to do with linguistics, that was new to me.

I can't recall ever having used it, other than in this discussion, and is unlikely that I will use it in the future, so nobody would ask me - thus maintaining Steve's 100%. Otherwise, its 99.9999 ...%.
