ABSTRACT
Adults in the U.S. and China were asked to make judgments about the existence of a variety of scientific and religious entities, including God, germs, and evolution. Overall, participants expressed more confidence in the existence of scientific as compared to religious entities. This differential confidence in the two domains emerged in China as well as in the U.S. Moreover, it emerged even when participants were questioned about items attracting a lower overall level of consensus. Nevertheless, the religious beliefs of individual participants moderated the degree of differentiation between scientific and religious entities. Adults reporting low levels of religiosity expressed greater belief in the existence of scientific than religious entities but adults reporting high levels of religiosity expressed equivalent levels of belief in the existence of each domain. This pattern emerged in both China and the U.S. Testimony about unobservable phenomena has a similar impact on adults' pattern of beliefs across two historically distinct cultures.
