Which writing style typically requires the most research to back up arguments?

Persuasive writing is characterized by the author's effort to convince the reader of a particular viewpoint or to take a specific action. This writing style often requires substantial research to strengthen the arguments presented. Writers must gather credible evidence, statistics, expert opinions, and examples to support their claims effectively. The strength of persuasive writing lies in its ability to persuade the audience through logical reasoning and solid evidence, making the research component critical.

In contrast, narrative writing focuses primarily on storytelling and personal experiences, where the primary goal is to engage the reader through a compelling plot rather than scholarly support. Expository writing aims to inform or explain a topic clearly and concisely, utilizing facts and information, but does not typically strive to persuade the reader to adopt a specific viewpoint. Technical writing is used to convey complex information in fields such as technology and science, emphasizing clarity and usability over persuasion. While all these styles may require some level of research, persuasive writing stands out for its need to provide substantiated arguments to effectively convince its audience.
