Sharing responsibility with a machine

More and more often the partner in this decision is not another human but, instead, a machine. Here we ask whether a machine partner affects our responsibility, our perception of the choice and our choice differently from a human partner. We use a modified dictator game with two joint decision makers: either two humans or one human and one machine. We find a strong treatment effect on perceived responsibility. We do, however, find only a small and insignificant effect on actual choices.
