I often ask, "what new fact could change my opinion about this?" it isn't a simple question. it requires you go upstream of your opinion and consider why or what caused you to think it, and then ask -even upstream of that- if there is some principle or axiom that is yielding an interpretation of that cause.

questions like: would I still think this if I were happier; do I have a belief about my status that the circumstances do not reflect; do I share an ontology with this being at all; do I fear other consequences of agreeing with them?

the irony of authority is it usually means dealing with someone who doesn't have the authority to compromise, and if you don't humiliate them for this fact that hangs over everything they do, they will often at least use their discretion.
