The document discusses the concept of "suspension of disbelief" which refers to a reader's willingness to accept fantastical elements in a story. It was coined by Samuel Taylor Coleridge who said readers would suspend judgement of implausible narratives if the writer infused human interest and truth. In the 20th century, the phrase was used more loosely to imply it was the reader's responsibility. Coleridge introduced the concept to explain how modern audiences could enjoy stories involving the supernatural.
