Many important contests, such as job interviews and political debates, are presented in sequential order. Previous studies find serial position effects such that the later presenter has a higher probability of a win. However, no previous studies use both random assignments of contestants and a large number of contestants and judges. We use Immortal Songs 2, a popular TV program that satisfies both conditions, to confirm the findings of serial position effects. In addition, Immortal Songs 2 has round-by-round competition rules. The first round is a competition between the first and second contestants. Then, the winner of the first round is announced. The second round is a contest between the winner of the first round and the third contestant. As the rounds continue, the winner of the previous round should have a higher probability of winning in theory, but, in fact, the second contestanti¯s probability of winning is always 0.5.

许多重要的竞赛，例如求职面试和政治辩论，都是按顺序呈现的。先前的研究发现了连续位置效应，使得后来的演讲者获胜的可能性更高。然而，之前的研究没有同时使用参赛者的随机分配和大量参赛者和评委。我们使用满足这两个条件的流行电视节目《不朽之歌 2》来确认序列位置效应的发现。另外，仙歌2有回合制比赛规则。第一轮是第一名和第二名选手之间的比赛。然后，宣布第一轮的获胜者。第二轮是第一轮的获胜者和第三名选手之间的较量。随着回合的继续，
