有这样一个实验:一位长跑运动员参加一个5人小组的比赛,赛前教练对他说,据我了解,其他4个人实力并不如你。结果,这个运动员轻松跑了个第一名。后来,教练又让他参加了另外一个10人小组的比赛,教练把其他人平时的成绩拿给他看,他发现别人的成绩并不如自己,他又轻松地跑了个第一名 There is such an experiment: A long-distance runner participates in a 5-person team game. The coach said to him before the match that according to my understanding, the other 4 individuals are not as strong as you. As a result, this athlete easily took first place. Later, the coach asked him to participate in another 10-man team game. The coach showed him other people’s usual results. He found that other people’s achievements were not as good as they were. He easily took first place.
