What role does evidence play in an effective argument?

In an effective argument, evidence plays a critical role as it supports or counters a specific claim. This means that evidence is not just background information but is fundamental to establishing the validity of the argument being presented. When evidence is used effectively, it lends credibility, helps to persuade the audience, and can clarify or reinforce the point being made.

Using relevant and reliable evidence allows the speaker or writer to substantiate their claims, making their argument more convincing and grounded in facts rather than opinions. This process helps the audience to understand the rationale behind the argument and allows them to engage critically with the material presented. By demonstrating how evidence directly relates to the claims, the argument becomes stronger and more compelling.
