n. The tendency for automatic spell-checking software to replace some words with inappropriate or incorrect alternatives.
And then "the Cupertino effect": typos introduced by the very "autocorrect" software intended to save us from error. Ah, the typographical treason of these invisible servants!
On the plus side, though, we’d have no more problems with the Cupertino effect — spellcheck software’s tendency to suggest inappropriate words to replace misspellings and words not in its dictionary, such as suggesting "Cupertino" for "co-operation."
Of course, we take great care in the production of our own texts. Most of us are now aware of the 'Cupertino effect', and we have added 'cooperation' to the custom dictionary in our spelling checker.
Many thanks to Ben Zimmer for digging up the earliest citation.
