Okay lets say morality is like primality. What happens if I get morality wrong? If my ability to test primes is faulty my encryptions are more likely to be broken and I will give 5 presents to my 3 nephews and expect them to be able to divide them evenly, causing familial tension. The latter example would still be true even if societies primality detection is broken. What are the consequences if I and society get morality wrong? Lets say society thinks it is not immoral to kill babies under 6 months (not that it is a good thing to do, but neutral). What effects would the evil actions have, such that we could recognise them and potentially correct our morality detection?
