What characterizes a strong argument?

A strong argument is characterized by a reasoned claim supported by evidence. This means that the argument is built on a logical foundation where assertions are backed up by facts, statistics, expert opinions, or credible sources. This structure allows the audience to see the validity of the argument, as they can evaluate the evidence presented and understand how it relates to the claim. The use of evidence not only strengthens the argument but also enhances the speaker's credibility, as it shows that the speaker has done their research and values truth over mere opinion.

In contrast, unsubstantiated claims lack the backing of reliable evidence, making them less convincing. Personal opinions without evidence do not provide the necessary support to persuade others effectively because they are subjective and may not resonate with all audience members. Purely emotional appeals may evoke feelings but do not necessarily provide rational justifications, which leaves the argument vulnerable to skepticism. Therefore, a well-supported argument that combines logical reasoning and evidence is essential for effective persuasion in public speaking.
