Authoritarians change their customs more slowly than nonauthoritarians and follow authorities, not peers.

Evidence

I do not mean to imply that the authoritarian’s adherence to traditional social norms has been cast in iron and cannot be changed in a lifetime. We shall see that authoritarian students today are more likely to have sex before marriage than they were in years past. But their adherence to their customs will prove more resistant to change than the nonauthoritarian’s, and it is relatively more likely to be influenced by the pronouncements of the established authorities than by the behavior of peers. — Bob Altemeyer, The Authoritarian Specter, 166
