Our overall question is, What do humans compute that enables them to track moral attributes?
From the two bodies of research on moral dumbfounding and moral disengagement, we can conclude that any answer to this question must be consistent the discovery that moral intuitions are sometimes, but not always, a consequence of reasoning from known principles.
To understand the roles of feeling and reasoning in moral intuitions, we must identify or create a theory that can solve the puzzles, is theoretically coherent and empirically motivated, and generates novel testable predictions.
characteristically consequentialist : According to Greene, a judgement is characteristically consequentialist (or characteristically utilitarian) if it is one that in ‘favor of characteristically consequentialist conclusions (eg, “Better to save more lives”)’ (Greene, 2007, p. 39). According to Gawronski, Armstrong, Conway, Friesdorf, & Hütter (2017, p. 365), ‘a given judgment cannot be categorized as [consequentialist] without confirming its property of being sensitive to consequences.’
characteristically deontological : According to Greene, a judgement is characteristically deontological if it is one that in ‘favor of characteristically deontological conclusions (eg, “It’s wrong despite the benefits”)’ (Greene, 2007, p. 39). According to Gawronski et al. (2017, p. 365), ‘a given judgment cannot be categorized as deontological without confirming its property of being sensitive to moral norms.’
Drop : A dilemma; also known as Footbridge. A runaway trolley is about to run over and kill five people. You can hit a switch that will release the bottom of a footbridge and one person will fall onto the track. The trolley will hit this person, slow down, and not hit the five people further down the track. Is it okay to hit the switch?
moral disengagement : Moral disengagement occurs when self-sanctions are disengaged from inhumane conduct. Bandura (2002, p. 103) identifies several mechanisms of moral disengagement: ‘The disengagement may centre on redefining harmful conduct as honourable by moral justification, exonerating social comparison and sanitising language. It may focus on agency of action so that perpetrators can minimise their role in causing harm by diffusion and displacement of responsibility. It may involve minimising or distorting the harm that follows from detrimental actions; and the disengagement may include dehumanising and blaming the victims of the maltreatment.’
tracking an attribute : For a process to track an attribute is for the presence or absence of the attribute to make a difference to how the process unfolds, where this is not an accident. (And for a system or device to track an attribute is for some process in that system or device to track it.) Tracking an attribute is contrasted with computing it. Unlike tracking, computing typically requires that the attribute be represented. (The distinction between tracking and computing is a topic of Two Questions about Moral Intuitions.)
Trolley : A dilemma; also known as Switch. A runaway trolley is about to run over and kill five people. You can hit a switch that will divert the trolley onto a different set of tracks where it will kill only one. Is it okay to hit the switch?
