Deontic reasoning reviewed: psychological questions, empirical findings, and current theories

Deontic reasoning is concerned with questions of whether actions are forbidden or allowed, obligatory or not obligatory. This article reviews empirical findings and psychological theories on deontic reasoning with regard to three questions that have guided psychological research during the last decades: How do people's deontic capabilities develop? How well do people perform in deontic reasoning tasks? And how do they represent deontic rules? In conclusion, it is discussed why deontic reasoning-despite astonishing, early developing competencies-is still a complex cognitive activity.
