Why is making assertions without evidence problematic in a debate?

Making assertions without evidence is problematic in a debate because it fundamentally lacks the necessary support and credibility, which are essential to strengthen an argument. In a debate setting, arguments need to be backed by verifiable facts, data, and logical reasoning. When a debater presents claims without evidence, it leaves those claims open to scrutiny and skepticism, making it difficult for the audience or judges to trust or accept the assertions being made. This undermines the overall impact of the argument, as arguments grounded in solid evidence are more persuasive and compelling. The lack of empirical support not only weakens the debater’s position but also detracts from the overall quality of the debate. Therefore, the reliance on evidence is crucial for establishing credibility and effectiveness in any argumentation.
