"The idea was to look more at the more moral and ethical implications of how alcohol might affect decision-making," said Aaron Duke, one of the researchers.* His team found a correlation between each subject's level of intoxication and his or her willingness to flip the switch or push the person—the drunker the subject, the more willing he or she was to kill one hypothetical person for the sake of the hypothetical many. This choice follows the logic of utilitarianism: More good is done by saving five people than harm is done by killing one.
This "really undermines the notion that utilitarian preferences are merely the result of more deliberation," said Duke, who also co-authored a paper on the study, charmingly titled, "The drunk utilitarian: Blood alcohol concentration predicts utilitarian responses in moral dilemmas."
There's a fabulous irony in the idea that drunk people are emotionally steeled rationalists who are willing to do whatever it takes to save lives. But Duke and his research partner, Laurent Bègue, aren't necessarily arguing that drunk people are ace philosophers and logicians; it's more that their findings challenge common assumptions about how people make decisions.
