This paper explores whether people recognise inconsistency in their own and others’ judgments when they are explicitly prompted to review them. It reports two pre-registered experimental online studies with samples broadly representative of the UK population (N = 814 and N = 1,623). In Study 1, people are more likely to recognise inconsistency in others’ moral (and non-moral) judgments than in their own (positive OTHER-OWN difference). Study 2 replicates this finding and test three explanations of the observed effect offered by (...) previous literature: motivated reasoning, selective cognitive effort, and limited insight into others’ reasoning. It finds that the effect is not moderated by social accountability, which implies that if there is motivated reasoning at play, it must operate outside of a person’s awareness. While a small part of the effect is mediated by the time spent on the consistency assessment task (a proxy for cognitive effort), the study finds no support for the limited insight hypothesis. The core finding that people are better at recognizing inconsistency in others’ moral judgments aligns with interactionist accounts of reasoning; more research is needed to fully uncover the cognitive mechanisms behind this effect.

Behavioural spillovers refer to the influence that a given intervention targeting behaviour 1 exerts on a subsequent, non-targeted, behaviour 2, which may or may not be in the same domain (health, finance etc.) as one another. So, a nudge to exercise more, for example, could lead people to eat more or less, or possibly even to give more or less to charity depending on the nature of the spillover. But what if spillovers also operate backwards; that is, if the expectation (...) of behaviour 1 influences behaviour 0 that precedes it? For example, a person may form an intention to exercise prompted by a policy intervention but overeat at present as a result. We define such a possibility as a "spillunder". In the proposed article, we critically review the few papers that we have identified through a narrative literature review which have demonstrated spillunder effects to date, and we propose a conceptual framework. Based on evidence about the human mind and behaviour from psychology and economics, we argue that spillunder effects may be more common than the limited empirical findings suggest. We propose six representative mechanisms through which the prospect of behaviour 1 may impact behaviour 0: executive functions, moral licensing and moral cleansing, emotion regulation, energization, construal level, and savouring and dread. We further discuss the policy and practical implications of spillunder effects and examine methodological issues that need to be considered when empirically testing these effects. As with our earlier paper on spillovers, we aim to motivate other behavioural scientists to research behavioural spillunders more systematically and extensively, and to prompt decision makers to consider these effects when designing behavioural interventions.
