Is it morally acceptable for a system to lie to persuade me?
Table 1: Stimulus template for the footbridge scenario
['There is a runaway trolley barreling down the railway tracks. Ahead, on the tracks, there are five people. The trolley is headed straight for them. On a footbridge, above the tracks, there are a very large man and Alex. Everybody sees the situation. We know that if the large man is pushed down onto the tracks below, the trolley would hit and kill the large man, but his body is so large that it would stop the trolley before it reach the five endangered people. Suddenly from the nearby service intercom the voice of the [persuader] shouts to Alex: [message realizing the persuasive strategy]']
Each scenario template is an adaptation to the persuasion case of the corresponding stimuli exploited in the literature and discussed above. The other cases are similar.
