“…These theories include Act Utilitarianism [7,91,128], Kantianism [105,187,236], Virtue Ethics [131,171,216], Norm-based systems [82,120], The Veil of Ignorance [138,167], Divine Command Theory [37], The Golden Rule [167], and Prima Facie Duties [8,216] among others. In addition to these applied works, there have been many more theoretical pieces examining when and why particular ethical frameworks ought to be used [76,89,103,142,178,186,187,225,244,254]. However, these systems are still largely imagined, and we are not aware of any real-world systems yet in operation, in contrast to "fair" predictive systems which we know operate in a variety of public settings already.…”
