 Accepting the distinction between primary and secondary propriety induces a problem for the intuitive support for the various theories. A large part of the intuitions that serve to support one or the other norm theory relies on raw intuitions about what one should or shouldn’t assert in some situation, or what is proper or improper to assert there. If there are several ways an assertion can be proper or improper, then it is not easy to see which concept of propriety is being tracked by these intuitions. The idea is that a particular intuition that seems to disconfirm a particular normative theory can be explained away by saying that it does not in fact track the primary propriety, but instead only some secondary propriety. Since intuitions don’t come labeled as “primary” and “secondary”, there is a risk of a substantial underdetermination of theory by data (stressed by Pagin 2016b): two theorists need not agree about whether or not an intuition about a particular case supports a certain theory.
