Deontic and epistemic reasoning in children revisited: Comment on Dack and Astington

► Children require reference to authority in order to accept an utterance as a norm. ► Once accepted as a norm, they reason as effectively as adults. ► They reason as poorly when testing the truth of epistemic sentences. ► This is not due to differences in complexity of epistemic and deontic utterances. ► Norms are distinct from reciprocal obligations.
