Premise: A permissive society is a society in which social norms become increasingly liberal, especially with regard to sexual freedom. This usually accompanies a change in what is considered deviant. While typically preserving the rule "do not harm others" (harm principle/non-aggression principle), a permissive society would have few other moral or legal codes (no victimless crimes, for example).
Hypothesis: Permissive societies adopt social norms that are increasingly conservative.
