摘要

实验证据表明,当人们不得不为某一特定立场辩护时,他们会说服自己该立场在事实和道德上具有优越性。这种自我说服限制了沟通解决冲突和减少两极分化的潜力。我们在国际辩论比赛的现场环境中测试了这种现象,这些比赛随机分配有经验和有动力的辩手来辩论一个主题运动的一方。我们在事实信仰和对自己立场的自信中找到自我说服。效应大小比实验室小,但对一个小时的争论和十倍的准确性激励是强有力的。(jel c93, d12, d72, d83, d91, i23)

Self-Persuasion: Evidence from Field Experiments at International Debating Competitions
Laboratory evidence shows that when people have to argue for a given position, they persuade themselves about the position’s factual and moral superiority. Such self-persuasion limits the potential of communication to resolve conflict and reduce polarization. We test for this phenomenon in a field setting, at international debating competitions that randomly assign experienced and motivated debaters to argue one side of a topical motion. We find self-persuasion in factual beliefs and confidence in one’s position. Effect sizes are smaller than in the laboratory, but robust to a one-hour exchange of arguments and a tenfold increase in incentives for accuracy. (JEL C93, D12, D72, D83, D91, I23)
