Moral parochialism misunderstood: a reply to Piazza and Sousa

Our paper [1] compared two competing hypotheses. The hypothesis that we label universalistic moral evaluation holds that a definitional feature of reasoning about moral rules is that, ceteris paribus, judgements of violations of rules concerning harm, rights or justice will be insensitive to spatial or temporal distance or the opinions of authority figures. The hypothesis that we label moral parochialism, consonant with a variety of theories of the evolutionary origins of morality, holds that, because moral judgements primarily serve to navigate local social arenas, remote events will not activate the mechanisms that generate negative moral evaluation to the same extent as events occurring in the here and now, whereas the consent of local authority figures will temper condemnation. Hence, moral parochialism predicts that the collective output of the faculties responsible for moral judgement will exhibit a reduction in the severity of judgement as a function of spatial or temporal distance or the opinions of local authority figures. We provided evidence from seven diverse societies, including five small-scale societies, showing that such reductions in severity judgements exist in all of the societies examined. Piazza and Sousa [2] argue that our data do not support parochialism, and instead support universalism, because (1) Only a minority of our participants reversed their initial judgement of the wrongness of an action (from wrong to not wrong or good) when it was subsequently framed as having occurred long ago or far away, or as having been sanctioned by authority figures. (2) Our use of graduated moral judgements, rather than dichotomous judgements, is inappropriate. (3) Only a minority of our participants diminished the severity of their initial judgement of the wrongness of an action when it was subsequently framed as having occurred long ago or far away, or as having been sanctioned by an important person. These objections stem from misunderstandings of moral parochialism and the evolutionary reasoning behind it

Normative Bias and Adaptive Challenges: A Relational Approach to Coalitional Psychology and a Critique of Terror Management Theory

Adherence to ingroup ideology increases after exposure to death-related stimuli, a reaction that proponents of terror management theory (TMT) explain as a psychological defense against the uniquely human existential fear of death. We argue that existential concerns are not the relevant issue; rather, such concepts can be subsumed under a larger category of adaptive challenges that prime coalitional thinking. We suggest that increases in adherence to ingroup ideology in response to adaptive challenges are manifestations of normative mental representations emanating from psychological systems designed to enhance coordination and membership in social groups. In providing an alternative to TMT, we (1) explain why the theory is inconsistent with contemporary evolutionary biology, (2) demonstrate that mortality-salience does not have the unique evocative powers ascribed to it by TMT advocates, and (3) discuss our approach to coalitional psychology, a framework consistent with modern evolutionary theory and informed by a broad understanding of cultural variation, can be employed to help account for both the corpus of results in TMT research and the growing body of findings inconsistent with TMT’s predictions

The case of the drunken sailor: on the generalisable wrongness of harmful transgressions

There is a widespread conviction that people distinguish two kinds of acts: on the one hand, acts that are generalisably wrong because they go against universal principles of harm, justice, or rights; on the other hand, acts that are variably right or wrong depending on the social context. In this paper we criticise existing methods that measure generalisability. We report new findings indicating that a modification of generalisability measures is in order. We discuss our findings in light of recent criticisms of moral/conventional research
