1. Is the evidence relevant to the speaker's claim? Does the evidence directly support the point the speaker is trying to make? Or is it tangential or unrelated?
2. Is the evidence credible and reliable? What is the source of the evidence? Is it from a reputable source with expertise in the topic? Are there biases or agendas that might influence the evidence?
3. Is the evidence sufficient to support the claim? Does the speaker provide enough evidence to be convincing, or is the evidence limited or anecdotal?
Asking these questions can help you determine whether a speaker's evidence is strong and trustworthy, and whether you should accept their claims.
