Final answer:
Authors conduct research in argumentative essays to find evidence to support their arguments.
Step-by-step explanation:

Authors need to gather facts, statistics, examples, and expert opinions to back up their claims and make their argument persuasive and credible. Without conducting research, authors would be relying solely on their own opinions, which would weaken their argument and make it less compelling.
