It seems like you’re not using this definition consistently. For example, in (3), the speaker doesn’t care that any information at all is conveyed since the purpose is reinforcing their own belief. Several of the others appear to be beliefs that would motivate someone to say “I like red” rather than what they intend to convey to the listener (in (7) what is intended to be conveyed is “I’m committed to support you.”)

You’re right, I wrote this bit early on, then didn’t refactor.
I just changed it a bit. I’m sure with more thought we could have a better definition here.
