 As an example, consider a community that abides by strict norms of honesty. A person who, upon entering the community, systematically violates these norms will certainly be met with hostility, if not utterly excluded from the group. But suppose that a large group of thieves makes its way into this community. In due time, people would cease to expect honesty on the part of others, and would find no reason to be honest themselves in a world overtaken by crime. In this case, probably norms of honesty would cease to exist, as the strength of a norm lies in its being followed by many of the members of the relevant group (which in turn reinforces people’s expectations of conformity).
