In our paper, we reported cross-cultural differences in how the religious environment of a child negatively impacted their sharing, their judgments of the actions of others, and how their parents evaluated them. An error in this article, our incorrect inclusion of country of origin as a covariate in many analyses, was pointed out in a correspondence from Shariff, Willard, Muthukrishna, Kramer, and Henrich ( https://doi.org/10.1016/j.cub.2016.06.031 ). When we reanalyzed these data to correct this error, we found that country of origin, rather than religious affiliation, is the primary predictor of several of the outcomes. While our title finding that increased household religiousness predicts less sharing in children remains significant, we feel it necessary to explicitly correct the scientific record, and we are therefore retracting the article. We apologize to the scientific community for any inconvenience caused.
