Short answers, pulled from the story.
Non-fiction is any document or media content that attempts, in good faith, to convey information only about the real world, rather than being grounded in imagination. It typically aims to present topics objectively based on historical, scientific, and empirical information.
Non-fiction and narrative fiction are the two fundamental approaches to story and storytelling. Fiction is largely populated by imaginary characters and events, while non-fiction conveys information about the real world and prioritizes simplicity, clarity, and directness.
Yes, specific claims in a non-fiction work may prove inaccurate, but the sincere author aims to be truthful at the time of composition. Including information the author knows to be untrue is usually regarded as dishonest, and open falsehoods would discredit it as non-fiction.
Based on the author's intention, the main genres of non-fiction are instructional, explanatory, discussion-based, report-based or non-chronological, opinion-based or persuasive, and relating or chronological recounting. These take forms such as academic texts, history books, life writings, criticism, news, persuasive writing, and reference works.
Creative nonfiction is a term used by the publishing and bookselling businesses to distinguish works with a more literary or intellectual bent from the bulk of non-fiction subjects.
The boundaries between fiction and non-fiction are continually blurred and argued upon, especially in biography. Virginia Woolf described the aim of biography as welding granite-like truth and rainbow-like personality into one seamless whole, a problem she said biographers for the most part failed to solve.
