Abstract

I argue that the Doctrine of Double Effect is accepted because of unreliable processes of belief-formation, making it unacceptably likely to be mistaken. We accept the doctrine because we more vividly imagine intended consequences of our actions than merely foreseen ones, making our aversions to the intended harms more violent, and making us judge that producing the intended harms is morally worse. This explanation fits psychological evidence from Schnall and others, and recent neuroscientific research from Greene, Klein, Kahane and Schaich Borg. It explains Mikhail and Hauser's ‘universal moral grammar’ and an interesting phenomenon about Double Effect cases noted by Bennett. When unequally vivid representations determine our decisions, we typically misjudge the merits of our options and make mistakes. So if Double Effect is a product of unequal vividness, it is likely to be mistaken. This argument, I claim, fits Berker's specifications for good empirically grounded arguments in ethics.

7 McIntyre, ‘Doing Away With Double Effect’, p. 219. McIntyre argues that Double Effect examples can't be captured under any simple principle. They provide a ‘gallery of miscellaneous objections to simple forms of direct consequentialism that can be expressed, with more or less strain, using the distinction between intended and merely foreseen consequences. They are tied together by nothing more penetrating than the claim that the distinction between what an agent foresees and what an agent intends sometimes matters, and matters a great deal, to moral evaluation’ (‘Doing Away With Double Effect’, p. 255).

10 Here I must take ‘harms intended’ to include harms close to what we intend. The ‘straightforward view’ of intention in the section on Bennett's phenomenon will characterize them as not really intended.

29 Kahane et al., ‘Neural Basis’, p. 399. One shortcoming of Kahane's experiments is that his DI cases and UI cases are entirely different, with different sets of harms. This is unlike McIntyre's trolley and bomber examples, which involve similar situations and pair the same harms against each other – 1 dead versus 5 in both trolley cases, and the same number of deaths in each bomber case. Kahane thus doesn't control for the possibility that one set of harms arouses more emotion in subjects than the other. Furthermore, five UI cases involve lying while no DI cases do.

Schaich Borg also found less activity in the right angular gyrus and superior frontal gyrus in Double Effect cases, which she associates with cognition. She suggests that this results from subjects being dumbfounded by their intuitive judgements (p. 815).

40 I take this argument to be subject to the most severe problem that Berker presents for the best neuroscientific argument against deontology he considers: that instead of drawing on the force of any empirical results, it simply rests on armchair identification of some factors as morally relevant and others as irrelevant (Berker, ‘Normative Insignificance’, pp. 325–6).
