 Also Brennan, Eriksson, Goodin, and Southwood (2013) argue that norms have a function. Norms function to hold us accountable to each other for adherence to the principles that they cover. This may or may not create effective coordination over any given principle, but they place us in positions where we may praise and blame people for their behaviors and attitudes. This function of accountability, they argue, can help create another role for norms, which is imbuing practices with social meaning. This social meaning arises from the expectations that we can place on each other for compliance, and the fact that those behaviors can come to represent shared values, and even a sense of shared identity. This functional role of norms separates it from bare social practices or even common sets of desires, as those non-normative behaviors don’t carry with them the social accountability that is inherent in norms. The distinctive feature of the Brennan et al. account of norms is the centrality of accountability: this feature is what distinguishes norms from other social practices.
