"Unarbitrary" means the same thing as "nonarbitrary": based on reason or evidence, not on random choice or personal whim. In short, it means fair. It indicates decision-making that is justifiable and not based on personal preferences. Think of a teacher fairly grading papers based on a rubric. It stresses fairness and objectivity. While "nonarbitrary" is more commonly used, "unarbitrary" carries the same meaning 👍. Think of it as the opposite of a coin flip.
