The inconsistency between pro-environmental attitudes and behaviours, known as the “attitude-behaviour” gap, is exceptionally pronounced in scenarios associated with “green” choice. The current literature offers numerous explanations for the reasons behind the “attitude-behaviour” gap, however, the generalisability of these explanations is complex. In addition, the answer to the question of whether the gap occurs between attitudes and intentions, or intentions and behaviours is also unknown. In this study, we propose the moral dimension as a generalisable driver of the “attitude-behaviour” gap (...) and investigate its effectiveness in predicting attitudes, pro-environmental intentions and subsequent behaviours. We do so by using Hunt–Vitell’s moral philosophy-based framework of ethical decision-making, which conceptualises morality as the central decision-making parameter. The results from 557 US MTurk participants revealed that the manipulation of moral dimensions, specifically deontology and teleology, impacted ethical evaluation of presented dilemmas, however, failed to translate into subsequent intentions and behaviours. This finding suggests (i) that the moral dimension has an effect in shaping attitudes toward environmental issues, and (ii) that gap occurs between attitudes and intentions rather than intentions and behaviours. Further investigation of what strengthens and/or overrides the effects of the moral dimension would help understand the reasons why moral attitudes do not always translate into subsequent intentions and behaviours in the pro-environmental domain.

In this chapter we will review experimental evidence related to pharmacological moral enhancement. Firstly, we will present our recent study in which we found that a drug called propranolol could change moral judgements. Further research, which also investigated this, found similar results. Secondly, we will discuss the limitations of such approaches, when it comes to the idea of general “human enhancement”. Whilst promising effects on certain moral concepts might be beneficial to the development of theoretical moral psychology, enhancement of human (...) moral behaviour in general – to our current understanding – has more side-effects than intended effects, making it potentially harmful. We give an overview of misconceptions when taking experimental findings beyond the laboratory and discuss the problems and solutions associated with the psychological assessment of moral behaviour. Indeed, how is morality “measured” in psychology, and are those measures reliable? (shrink)

Previous studies have revealed the effect of interoceptive accuracy, a behavioral measure of the ability to feel physiological states and regulation for that, which origin emotion on decision-making such as gambling. Given that decision-making in moral dilemma situations is affected by emotion, it seems that IAcc also affects moral decision-making. The present study preliminarily investigates whether IAcc affects decision-making and emotional ratings such as regret for one’s own choices in moral dilemma situations. IAcc did not affect moral choice, but affected (...) regret ratings for one’s moral choice in portions of dilemma scenarios. Moreover, people with higher IAcc make deontological choices more rapidly than those with lower IAcc in self-related dilemma scenarios. These results suggest that people with higher IAcc feel stronger emotional conflicts about utilitarian choices but weaker conflicts about deontological choices than people with lower IAcc depending on the moral dilemma scenario.

Moral dilemmas are a useful tool to investigate empirically, which parameters of a given situation modulate participants’ moral judgment, and in what way. In an effort to provide moral judgment data from a non-WEIRD culture, we provide the translation and validation of 48 classical moral dilemmas in Persian language. The translated dilemma set was submitted to a validation experiment with N = 82 Iranian participants. The four-factor structure of this dilemma set was confirmed; including Personal Force, Benefit Recipient, Evitability, and (...) Intentionality. When comparing moral judgments of Iranian participants to those of Spanish and Italian participants’ from previous research with the same dilemma set, differences emerged. Iranian participants’ moral judgments were more deontological, than Spanish and Italian participants. Religiosity made participants’ moral judgments more deontological, and also dysphoric mood resulted in a more deontological response style. (shrink)

Two prominent theoretical frameworks in moral psychology, Moral Foundations and Dual Process Theory, share a broad foundational assumption that individual differences in human morality are dispositional and in part due to genetic variation. The only published direct test of heritability, however, found little evidence of genetic influences on moral judgments using instrumentation approaches associated with Moral Foundations Theory. This raised questions about one of the core assumptions underpinning intuitionist theories of moral psychology. Here we examine the heritability of moral psychology (...) using the moral dilemmas approach commonly used in Dual Process Theory research. Using such measures, we find consistent and significant evidence of heritability. These findings have important implications not only for understanding which measures do, or do not, tap into the genetically influenced aspects of moral decision-making, but in better establishing the utility and validity of different intuitionist theoretical frameworks and the source of why people differ in those frameworks.

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...

The standard way to test alternative descriptive theories of moral judgment is by asking subjects to evaluate (amongst others) sacrificial dilemmas, where acting classifies as a utilitarian moral judgment and not acting classifies as a deontological moral judgment. Previous research uncovered many situational factors that alter subject’s moral judgments without affecting which type of action utilitarianism or deontology would recommend. This literature review provides a systematic analysis of the experimental literature on the influence of situational factors on moral judgments in (...) sacrificial dilemmas. It analyses 53 articles in detail and reports mean effect sizes, as well as operationalizations, for 36 situational factors that significantly influence moral judgment. Moreover, the review discusses how the impact of situational factors relates to a dual process theory of moral judgment. It supports the view that utilitarian judgments are driven by controlled cognitive processes and shows that the drivers of deontological judgments depend on valence. (shrink)

Recent advances in virtual technologies have allowed the investigation of simulated moral actions in aversive moral dilemmas. Previous studies have employed diverse populations in order to explore these actions, with little research considering the significance of occupation on moral decision-making. For the first time, in this study we have investigated simulated moral actions in Virtual Reality made by professionally trained paramedics and fire service incident commanders who are frequently faced with and must respond to moral dilemmas. We found that specially (...) trained individuals showed distinct empathic and related personality trait scores and that these declined with years of experience working in the profession. Supporting the theory that these professionals develop resilience in moral conflict, reduced emotional arousal was observed during virtual simulations of a distressing dilemma. Furthermore, trained professionals demonstrated less regret following the execution of a moral action in virtual reality when compared to untrained control populations. We showed that, contrary to previous research, trained individuals made the same moral judgments and moral actions as untrained individuals, though showing less arousal and regret. In the face of increasing concerns regarding empathy decline in healthcare professionals, we suggest that the nature of this decline is complex and likely reflects the development of a necessary emotional resilience to distressing events.

In order to assess and understand human behavior, traditional approaches to experimental design incorporate testing tools that are often artificial and devoid of corporeal features. Whilst these offer experimental control in situations in which, methodologically, real behaviors cannot be examined, there is increasing evidence that responses given in these contextually deprived experiments fail to trigger genuine responses. This may result from a lack of consideration regarding the material makeup and associations connected with the fabric of experimental tools. In a two-year (...) collaboration, we began to experiment with the physicality of testing tools using the domain of moral psychology as a case study. This collaboration involved thinkering and prototyping methods that included direct contact and consideration of the materials involved in experimentation. Having explored the embodied nature of morality, we combined approaches from experimental psychology, moral philosophy, design thinking, and computer science to create a new testing tool for simulated moral behavior. Although the testing tool itself generated fruitful results, this paper considers the collaborative methodology through which it was produced as a route to highlight material questions within psychological research.

The COVID-19 pandemic continues to pose significant health, economic, and social challenges. Given that many of these challenges have moral relevance, the present studies investigate whether the COVID-19 pandemic is influencing moral decision-making and whether moralisation of behaviours specific to the crisis predict adherence to government-recommended behaviours. Whilst we find no evidence that utilitarian endorsements have changed during the pandemic at two separate timepoints, individuals have moralised non-compliant behaviours associated with the pandemic such as failing to physically distance themselves from (...) others. Importantly, our findings show that this moralisation predicts sustained individual compliance with government-recommended behaviours. (shrink)

Experimental research suggests that people draw a moral distinction between bad outcomes brought about as a means versus a side effect (or byproduct). Such findings have informed multiple psychological and philosophical debates about moral cognition, including its computational structure, its sensitivity to the famous Doctrine of Double Effect, its reliability, and its status as a universal and innate mental module akin to universal grammar. But some studies have failed to replicate the means/byproduct effect especially in the absence of other factors, (...) such as personal contact. So we aimed to determine how robust the means/byproduct effect is by conducting a meta-analysis of both published and unpublished studies (k = 101; 24,058 participants). We found that while there is an overall small difference between moral judgments of means and byproducts (standardized mean difference = 0.87, 95% CI 0.67 – 1.06; standardized mean change = 0.57, 95% CI 0.44 – 0.69; log odds ratio = 1.59, 95% CI 1.15 – 2.02), the mean effect size is primarily moderated by whether the outcome is brought about by personal contact, which typically involves the use of personal force.

Many investigations of moral decision-making employ hypothetical scenarios in which each participant has to choose between two options. One option is usually deemed “utilitarian” and the other either “non-utilitarian” or “deontological”. Very little has been done to establish the validity of such measures. It is unclear what they measure, let alone how well they do so. In this exploratory study, participants were asked about the reasons for their decisions in six hypothetical scenarios. Various concerns contributed to each decision. Action decisions (...) occurred when utilitarian concerns dominated. Bystanding decisions resulted from different concerns or combinations of concerns dominating in different situations, with utilitarianism usually among participants’ concerns. None of the labels usually used for either decision therefore seems entirely appropriate. Five concerns were identified as necessary and sufficient to predict over 85% of participants’ decisions. This suggests great promise for future research, particularly in investigation of real-world moral decisions. (shrink)

Influential theories on moral judgments propose that they rely either on emotions or on innate moral principles. In contrast, the mental model theory postulates that moral judgments rely on reasoning, either intuition or deliberation. The theory allows for the possibility that intuitions lead to utilitarian judgments. This paper reports two experiments involving fifth-grade children, adolescents, and adults; the results revealed that children reason intuitively to resolve moral dilemmas in which action and inaction lead to different outcomes. In particular, the results (...) showed female children to be more utilitarian than female adults in resolving classical moral dilemmas: they preferred an action that achieved a good outcome for a greater number of people. Within the mental model theory’s framework there is no reason to expect that females and males differ in their ability to reason, but at the moment the results for females cannot be generalized to males who were not properly represented in the adults groups of the two experiments. The result revealing that (female) children are more utilitarian than (female) adults, which is hard to explain via many current theories, was predicted by the mental model theory. (shrink)

When experimental participants are given the chance to reflect and revise their initial judgments in a dynamic conversational context, do their responses to philosophical scenarios differ from responses to those same scenarios presented in a traditional static survey? In three experiments comparing responses given in conversational contexts with responses to traditional static surveys, we find no consistent evidence that responses differ in these different formats. This aligns with recent findings that various manipulations of reflectiveness have no effect on participants’ judgments (...) about philosophical scenarios. Although we did not find a consistent quantitative effect of format (conversation vs. static survey), conversational experiments still provide qualitative insights into debates about how participants are understanding (or misunderstanding) the scenarios they read in experimental studies, whether they are replacing difficult questions with questions that are more easily answered, and how participants are imagining the scenarios they read in ways that differ from what is explicitly stated by experimenters. We argue that conversational experiments—"Socratic questionnaires"—help show what is going on “under the hood” of traditional survey designs in the experimental investigation of philosophical questions.

The literature has shown that different types of moral dilemmas elicit discrepant decision patterns. The present research investigated the role of uncertainty in contributing to these decision patterns. Two studies were conducted to examine participants' choices in commonly used dilemmas. Study 1 showed that participants’ perceived outcome probabilities were significantly associated with their moral choices, and that these associations were independent from the dilemma type. Study 2 revealed that participants had significantly less preference for killing the individual when the outcome (...) probabilities were stated using the modal verb ‘will’ than when they were stated using the numerical phrasing of ‘100%’. Our findings illustrate a discord between experimenter and participant in the interpretation of task instructions. (shrink)
