I don’t think parties “are competing to get their preferred belief accepted” in typical persistent disagreements among people I respect. Instead:
They haven’t yet shared all their evidence and reasoning.
They won’t share all their evidence and reasoning, because the time and attention costs aren’t worth it.
A party has a small “part” which is doing something dishonest, but has no stake in the disagreement. For example, Alice believes in God and this colors her perception of Cold War geopolitics, with implications for present-day geopolitics; and part of Alice is dishonestly protecting her belief in God, but doesn’t need Bob to believe; but under this constraint Alice is having trouble articulating why Bob hasn’t convinced her about computer chip export controls.
A party doesn’t want to share all their evidence and reasoning because it’s secret, but maybe they can make an honest and convincing case with the nonsecret evidence.
ETA: 5. And yeah, sometimes people are trying to get the other person to believe something no matter if it’s true. Not all the time though.
