An effective argument has • Evidence • Ex. primary sources (photographs, original documents); statistics; authority figures or experts • Visuals can help highlight your point (ex. bold statistics, images, etc.)
An effective argument has • A logical conclusion that is supported by valid premises*. *A premise is a proposition upon which an argument is based and/or a conclusion is drawn. Example: Premise 1: John Doe is a doctor. Premise 2: All doctors treat patients. Conclusion: John Doe treats patients.
Avoid logical fallacies or defects in arguments that cause them to be invalid. • Executions are moral because we must have a death penalty to discourage violent crime. • You would think that taxes should be lowered because you are a Republican [and therefore your argument about taxes should be rejected].

Tips • Define your terms. • Be consistent in your terminology. • Rephrase key points to make sure they are understood.
