If you believe “I was being reasonable in that fight with my partner, and he was being unreasonable,” a hypothetical test might go something like this: Suppose another person, an objective third party, is given all of the relevant details about the fight, and is asked to judge which of you two is being more reasonable. If he judges in your favor, you win $1,000; if not, you lose $1,000. How confident do you feel that you would win that bet?
