A study on the rebuttal fallacy in BP debates
英国议会制辩论中反驳的有效性研究

摘要

本研究旨在深入分析在大学英语辩论赛中辩手们所犯的反驳谬误，探讨了这些谬误背后的原因，并提出了相应的建议。本文收集了两次比赛里六场辩论中24名辩手的辩论发言和评委的反馈，运用T.Edward Dame的反驳谬误理论对辩手所犯的谬误进行分类分析。结果显示，“否认反证谬误”的发生频次最高，其中，中低水平的辩手更容易发生这种谬误。在辩论中，最容易发生反驳谬误的角色是反对党领袖，而党鞭所犯的谬误则最为致命。通过不断的研究分析，本研究总结出反驳谬误的产生原因主要是缺乏清晰逻辑及论证机制以及对角色职责认知不足，并对此给予了相应的改进措施。

Abstract

This study aims to conduct an in-depth analysis of the rebuttal fallacies that often occur in college English debate competition, discuss the reasons behind these rebuttal fallacies, and put forward some suggestions. Based on T. Edward Dame’s theory of refutation fallacies, this paper classifies and analyzes the rebuttal fallacies in the speeches of 24 debaters in six debates in two competitions and the feedback of judges. According to the study, the frequency of denying the counter evidence is the highest. What’s more, the middle level debaters and the novice were more likely to make this fallacy. In BP debate, LO is the person who is most likely to make rebuttal fallacies, while the fallacies committed by Whip is the most fatal. Through a series of research and analysis, this study concludes that the main causes of rebuttal fallacy are the lack of clear logic and mechanism and the lack of cognition of roles and responsibilities. To improve this situation, this paper gives corresponding advice.
