Why is research considered important in persuasive writing?

Research is critical in persuasive writing primarily because it provides evidence to support arguments. When an author incorporates factual data, statistics, expert opinions, or specific examples, they bolster their claims and enhance their credibility. This evidence helps to convince the audience of the validity and importance of the writer’s viewpoint.

In persuasive writing, it is essential to present logical reasoning and informed opinions, and research serves as a solid foundation for this process. By grounding arguments in evidence, the writer not only gains authority but also helps the audience to understand and accept the main points being made. This is far more effective than relying solely on personal anecdotes or opinions, which may not resonate as deeply with audiences looking for factual backing.

The other choices reflect less effective strategies for persuasive writing, such as merely making the writing longer or substituting a thesis statement, which remains an essential element that outlines the main argument of the piece. Personal anecdotes can complement research but cannot serve as a substitute for the reliable evidence that research provides.
