These are usually easy to spot, though, because everyone knows "consbreastution" note constitution the letters "tit" in "cons titution are "censored" to "breast" and "buttbuttination" note assassination the letters "ass" in assassination are "censored" to "butt" aren't real words. Nowadays the proliferation of touchscreen devices has made such Auto-Incorrect issues much more common.Ī third variant, the Scunthorpe Problem, also known as the clbuttic mistake, is a variant where words are "misspelled" because a filter saw a string it construed as rude within a legit word and autocorrected it. The link with "cooperation" was the misspelling "coopertino". Trivia "Cupertino", an otherwise unremarkable small town in California, was in these spellcheckers' dictionaries because Apple Computer happens to be headquartered there. This variant used to sometimes be called the Cupertino Effect after numerous instances of "cooperation" being replaced by "Cupertino" in documents by early spellcheckers because they didn't recognize "cooperation" (even though they did recognize "co-operation"), with "Cupertino" being the closest match they could find in their dictionaries.
On the other hand, a mistyped word, proper noun, or even valid English word that isn't part of the dictionary (for whatever reason) can get "corrected" to something utterly preposterous, especially if the spell checker is set to "autocorrect". While most word processing programs also have grammar checkers, following their rules blindly is the sort of thing up with which your readers may not put, so many either don't use the feature or don't trust its suggestions. This leads to errors like those in this trope's name: rogue/rouge, angels/angles, and Satan/satin. If the mistyped word happens to be a legitimate word itself, the spell checker will let it go without mention. Some writers are infamously inclined to either not use a spellchecker at all (producing mistakes such as the numerous claims of "misspellings" on this page), or trust them blindly.
