Dual process models of higher cognition have become very influential in the cognitive sciences. The popular Default-Interventionist model has long favoured a serial view on the interaction between...

Studies with sacrificial moral dilemmas capture human variation in moral attitudes towards an extreme case of moral conflict between utilitarian and deontological principles. In this moral task, th...

De Neys makes a compelling case that the sacrificial moral dilemmas do not elicit competing “fast and slow” processes. But are there even two processes? Or just two intuitions? There remains strong evidence, most notably from lesion studies, that sacrificial dilemmas engage distinct cognitive processes generating conflicting emotional and rational responses. The dual-process theory gets much right, but needs revision.

In this commentary, I warn against a possible dual process misconception that might lead people to conclude that utilitarian judgments are normatively correct. I clarify how the misconception builds on (1) the association between System 2 and normativity in the dual process literature on logical/probabilistic reasoning, and (2) the classification of utilitarian judgments as resulting from System 2 processing in the dual process model of moral reasoning. I present theoretical and empirical evidence against both premises.

Dual-process theories of the mind emphasize how reasoning is an interplay between intuitive and reflective thinking. This paper aims to understand how the two types of processing interact in the moral domain. According to a ‘default-interventionist’ model of moral reasoning intuition and reflection are conflicting cognitions: intuitive thinking would elicit heuristic and deontological responses, whereas reflection would favour utilitarian judgements. However, the evidence for the default interventionist view is inconclusive and challenged by a growing amount of counterevidence in recent years. (...) The recent empirical findings favour an interdependent rather than conflicting view of the two types of information processing in the moral domain. In this view, which I call dual-process reflective equilibrium, intuition and reflection cooperate in moral reasoning to reach a reflective goal, which is supposedly normative justification. In sum, on the one hand, the scope of moral intuitions extends to selecting relevant information and calling for reflection whenever a problem presents conflicting aspects; on the other hand, the purpose of moral reflection is to rationalize pre-reflective intuitions to provide articulated and accessible reasons.

In four experiments, we asked subjects for judgements about scenarios that pit utilitarian outcomes against deontological moral rules, for example, saving more lives vs. a rule against active killing. We measured trait emotions of anger, disgust, sympathy and empathy, asked about the same emotions after each scenario. We found that utilitarian responding to the scenarios, and higher scores on a utilitarianism scale, were correlated negatively with disgust, positively with anger, positively with specific sympathy and state sympathy, and less so with (...) general sympathy or empathy. In a fifth experiment, we asked about anger and sympathy for specific outcomes, and we found that these are consistently predictive of utilitarian responding. (shrink)

Although lay notions in normative ethics have previously been investigated within the framework of the dual-process interpretation of the terror management theory (TMT), meta-ethical beliefs (subjective vs. objective morality) have not been previously investigated within the same framework. In the present research, we primed mortality salience, shown to impair reasoning performance in previous studies, to see whether it inhibits subjectivist moral judgments in three separate experiments. In Experiment 3, we also investigated whether impaired reasoning performance indeed mediates the effect of (...) mortality salience on subjectivism. The results of the three experiments consistently showed that people in the mortality salience group reported significantly less subjectivist responses than the control group, and impaired reasoning performance partially mediates it. Overall, the results are consistent with the dual-process interpretation of TMT and suggest that not only normative but also meta-ethical judgments can be explained by this model. (shrink)

There has been a longstanding controversy in research as to whether moral judgment is the result of an analytical or an intuitive process. Today, researchers increasingly recognize that moral judgments can be the result of both intuition and analysis, and that the two paths can lead to different results. This raises the question as to which of the two processes leads to a better moral judgment. The article develops a typology of moral problems depending on their moral uncertainty and moral (...) equivocality and links the derived types with analysis and intuition effectiveness. The typology considers four types of moral problems: compliance problems (low uncertainty, low equivocality), professional ethics problems (high uncertainty, low equivocality), conformity problems (low uncertainty, high equivocality) and ethical dilemmas (high uncertainty, high equivocality). The article argues that compliance and professional ethics problems are best solved analytically, whereas intuition is assumed to be more suitable for conformity problems and ethical dilemmas. Moreover, the article shows that it is not sufficient to contrast intuition with analysis alone. The higher the moral uncertainty, the more important the interplay of intuition and analysis becomes in making moral judgments. (shrink)

In the trolley problem, a well-known moral dilemma, the intuitive process is believed to increase deontological judgments, while deliberative reasoning is thought to promote utilitarian decisions. Therefore, based on the dual-process model, there seems to be an attempt to save several lives at the expense of a few others in a deliberative manner. This study examines the validity of this argument. To this end, we manipulate decision-making time in the standard trolley dilemma to compare differences among 119 Japanese female undergraduates (...) under three conditions: intuitive judgment, deliberative judgment, and judgment after a group discussion. The current results demonstrate that utilitarian judgments decreased from 52.9% in the intuition condition to 43.7% in the deliberation condition and 37.0% after the discussion. Additional analysis suggests that the decrease in utilitarian judgments may be related to psychological unwillingness to assume responsibility for the lives of others rather than to an increase in deontological judgments. Finally, these results are discussed from an adaptationist perspective. (shrink)

It is not yet clear which response behavior requires self-regulatory effort in the moral dilemma task. Previous research has proposed that utilitarian responses require cognitive control, but subsequent studies have found inconsistencies with the empirical predictions of that hypothesis. In this paper we treat participants’ sensitivity to utilitarian gradients as a measure of performance. We confronted participants (N = 82) with a set of five dilemmas evoking a gradient of mean utilitarian responses in a 4-point scale and collected data on (...) heart rate variability and on utilitarian responses. We found positive correlations between tonic and phasic HRV and sensitivity to the utilitarian gradient in the high tonic group, but not in the low tonic group. Moreover, the low tonic group misplaced a scenario with a selfish incentive at the high end of the gradient. Results suggest that performance is represented by sensitivity correlated with HRV and accompanied with a reasonable placement of individual scenarios within the gradient. (shrink)

How people distinguish well-justified from poorly justified arguments is not well known. To study the involvement of intuitive and analytic cognitive processes, we contrasted participants’ personal beliefs with argument strength that was determined in relation to established criteria of sound argumentation. In line with previous findings indicating that people have a myside bias, participants (N = 249) made more errors on conflict than on no-conflict trials. On conflict trials, errors and correct responses were practically equal in terms of response times (...) and mouse-tracking indices of hesitation. Similarly to recent findings on formal reasoning, these findings indicate that correct reasoning about informal arguments may not necessitate corrective analytic processing. We compared findings across four argument schemes but found few differences. The findings are discussed in light of intuitive logic theories and the notion that evaluating informal arguments could be based on implicit knowledge of argument criteria. (shrink)

This study utilized a combination of questionnaires and computational modeling to investigate age-related differences in moral judgments and the underlying cognitive mechanisms among the Chinese population. Study 1 employed the Oxford Utilitarianism Scale to investigate impartial beneficence and instrumental harm across different age groups. Results indicated that older adults scored significantly higher than younger adults on both dimensions even after controlling for level of education and gender. Study 2 utilized the CNI (consequences, norms, inaction) model to gain a more nuanced (...) understanding of age differences in moral judgments. Findings indicated that older adults exhibited less sensitivity to moral norms when forming moral judgments. This implies that older individuals psychologically lean toward utilitarianism and are less influenced by prevailing norms in their moral decision-making. (shrink)
