What is the association between religious affiliation and children’s altruism?

Decety et al. [1] examined the relationships between household religiosity and sociality in children sampled from six countries. We were keenly interested in Decety et al. [1]’s conclusions about a negative relationship between religiosity and generosity — measured with the Dictator Game — as our team has investigated related questions, often with potentially contrasting findings 2, 3, 4 and 5. We argue here that, after addressing peculiarities in their analyses, Decety et al. [1]’s data are consistent with a different interpretation.
