Explaining moral intuitions is one of the hot topics of recent cognitive science. In the present article we focus on a factor that attracted surprisingly little attention so far, namely the temporal order in which moral scenarios are presented. We argue that previous research points to a systematic pattern of order effects that has been overlooked until now: only judgments of actions that are normally regarded as morally acceptable are susceptible to be affected by the order of presentation, and this (...) in turn is only the case if the dilemma is immediately preceded by a dilemma in which the proposed action was considered as not morally acceptable. We conducted an experiment that largely confirmed this pattern and allowed us to analyze by what individual level responses it was generated. We argue that investigating order effects is necessary for approaching a complete descriptive moral theory. Furthermore, we discuss the implications of these findings for moral philosophy. (shrink)

Evidence about whether reflective thinking may be induced and whether it affects utilitarian choices is inconclusive. Research suggests that answering items correctly in the Cognitive Reflection Test (CRT) before responding to dilemmas may lead to more utilitarian decisions. However, it is unclear to what extent this effect is driven by the inhibition of intuitive wrong responses (reflection) versus the requirement to engage in deliberative processing. To clarify this issue, participants completed either the CRT or the Berlin Numeracy Test (BNT) – (...) which does not require reflection – before responding to moral dilemmas. To distinguish between the potential effect of participants’ previous reflective traits and that of performing a task that can increase reflectivity, we manipulated whether participants received feedback for incorrect items. Findings revealed that both CRT and BNT scores predicted utilitarian decisions when feedback was not provided. Additionally, feedback enhanced performance for both tasks, although it only increased utilitarian decisions when it was linked to the BNT. Taken together, these results suggest that performance in a numeric task that requires deliberative thinking may predict utilitarian responses to moral dilemmas. The finding that feedback increased utilitarian decisions only in the case of BNT casts doubt upon the reflective-utilitarian link. (shrink)
