Overdemanding Consequentialism? An Experimental Approach
Published online by Cambridge University Press: 28 April 2014
Abstract
According to act-consequentialism the right action is the one that produces the best results as judged from an impersonal perspective. Some claim that this requirement is unreasonably demanding and therefore consequentialism is unacceptable as a moral theory. The article breaks with dominant trends in discussing this so-called Overdemandingness Objection. Instead of focusing on theoretical responses, it empirically investigates whether there exists a widely shared intuition that consequentialist demands are unreasonable. This discussion takes the form of examining what people think about the normative significance of consequentialist requirements. In two experiments, the article finds that although people are sensitive to consequentialist requirements and, on average, find more extreme demands less reasonable, the level of disagreement with consequentialism falls short of qualifying as a widely shared intuition, even when demands are the highest. The article then ends with a general discussion of possible objections to its methods and its findings.

5 The recent position of scalar-consequentialism opts for the first alternative. See Norcross, Alastair, ‘Reasons without Demands: Rethinking Rightness’, Contemporary Debates in Moral Theory, ed. Dreier, J. (Oxford, 2006), pp. 38–53Google Scholar. The second alternative is less controversial, and several consequentialists have held it. Note, though, that the position of moral rationalism holds that this is conceptually not possible; see Portmore, Douglas W., Commonsense Consequentialism: Wherein Morality Meets Rationality (Oxford, 2011)CrossRefGoogle Scholar for this claim.

7 We mentioned the opposite of this in our discussion of the strategy of moderation above, i.e. that people can think that whatever they are morally required to do, they also have the most reason to do. But of course there is no reason to think that this is the only way people can think of morality and its relation to reasons for actions.
8 How about the case when the demands of consequentialism are found intuitively reasonable but not demanded by morality? Although this case is interesting – not least because one is curious why these demands are contrary to morality – it does not have relevance for us. For though the moral intuition now speaks against consequentialism, it does so on grounds other than its alleged overdemandingness. And this has no bearing on OD and hence is not something we need to be concerned with in this article.
9 Although it helped us to design our experiments, our main reason for making this distinction lay in our interest in the role of emotions not reported in this article. We hypothesized that whereas subjective demands should be strongly related to anticipated individual emotions in relation to the decision, objective demands should be more strongly related to anticipations concerning the emotions of others. Indeed, our analyses suggest that this is the case (research on this is ongoing and will be reported in another article). Beyond its role in relation to moral emotions and the design of our experiments, the distinction is, however, also helpful in identifying whether different kinds of demands are differentially susceptible to perceptions of overdemandingness and in examining whether such different kinds of demands interact with each other (i.e. do not merely have additive effects).
10 There were further questions that are not relevant to the present purpose. These focused, in particular, on anticipated emotional reactions to their decisions (see n. 9 for some details).
11 For the reasons given in n. 8, the other way that answers to the questions can come apart – when consequentialist demands are deemed reasonable but not demanded by morality – does not change our analysis.

13 2 (Objective Demands: high vs. low) × 2 (Subjective Demands: high vs. low) × 4 (Scenario: Africa vs. investigator vs. inheritance vs. fire) with the first two variables manipulated within subjects and the latter variable manipulated between subjects.
14 Objective demands: F(1, 136) = 13.88, p < .001, η2p = .093; subjective demands: F(1, 136) = 9.95, p = .002, η2p = .068.
15 There was no interaction between objective and subjective demands, F(1, 136) = .07, p = .78, η2p = .001. For the more conservative analysis, there was a tendency for such an interaction, F(1, 78) = 3.37, p = .070, η2p = .041, with a particularly pronounced effect of subjective demands when objective demands were low.
16 F(3, 136) = 2.49, p = .016, η2p = .072.

18 Objective demands: F(1, 136) = 10.91, p = .001, η2p = .074; subjective demands: F(1, 136) = 3.89, p = .051, η2p = .028.
19 All two-way interactions with the scenario manipulation: F(1, 136) < 1.08, p > .362, η2p < .023. Three-way interaction: F(3, 136) = 2.40, p = .070, η2p = .050.
