Full Idea

It is no part of supervenience that 'if p then q' entails 'if not p then not q'. To avoid such misunderstandings, it is common (though not more accurate) to describe supervenience in negative terms: no difference in A without a difference in B.

Gist of Idea

To avoid misunderstandings supervenience is often expressed negatively: no A-change without B-change
