Statistical inference also regresses to the mean. And the mean for spelling and grammar skills in society is regrettably low. In the last year or so I've noticed more and more that I have to fix misspellings or grammatical mistakes that were introduced by autocorrect. The most common culprits I notice are contractions (when I am sick I am not "I'll", "its" sometimes actually the contracted subject and verb, etc).
