50% MBTI性格类型
背景
Group fairness solution: 50% – each group gets the same treatment as each other group, so each group walks half the time regardless of the number of people per group or amount of suffering per person (or a coin is flipped to see which group walks each time) Individual equal action solution: 50% – each person has to walk as often as each other person (regardless of how much they suffer); hence each group walks half the time
