Non-fiction authors are writers who create works based on factual information, real events, and actual people. Their books can cover a wide range of subjects, including history, science, self-help, and biographies. Unlike fiction, which involves imaginative storytelling, non-fiction aims to inform, educate, or persuade readers about real-world topics. These authors often conduct extensive research to ensure accuracy and credibility in their writing. They may include interviews, statistics, and firsthand accounts to support their narratives. Notable non-fiction authors include Malcolm Gladwell, known for his insights into social psychology, and Michelle Obama, who shares her experiences in her memoir, Becoming.
