The development and importance of shared reality in the domains of opinion, morality, and religion.

The importance of shared reality emerges early in human development. Infants and young children notice when others share their beliefs, and information about shared beliefs influences their social judgments. This article reviews recent research on the importance of shared beliefs in three domains that have been widely investigated over the past several years-opinions, moral views, and religious beliefs. I argue that shared religious beliefs appear especially influential and suggest several reasons why this might be the case, including the perceived link between religion and morality as well as the strong role that religious beliefs play in personal identity. Future research can further test these possibilities.
