Computers and smartphones sometimes autocorrect what you type, so that your words are properly spelled. We know that this doesn't work perfectly. Suppose it did. Further, suppose that somehow there were also a perfect Ethical AutoCorrect, which if activated would alter any unethical action you were trying to perform into an ethical action. For example, if activated, and if extreme pacifism were true, then your attempt to switch the runaway trolley from the track with x people on it to the track with only x-1 people on it would fail. When you try to do what is indeed ethical, the Ethical AutoCorrect doesn't change a thing.
Two questions: First, is such an Ethical AutoCorrect even an coherent idea? Or is there something about ethics such that the very idea of an Ethical AutoCorrect is confused? Second, if it is a coherent idea, and if it were a live option, should you use it?
