An unreliable narrator is a storytelling device where the narrator's credibility is compromised. This can occur due to their limited knowledge, personal biases, or intentional deceit. As a result, the audience may question the truth of the events being described, leading to a more complex interpretation of the narrative. This technique is often used in literature and film to create suspense or provoke thought. Famous examples include The Catcher in the Rye by J.D. Salinger and the movie Fight Club. By presenting a skewed perspective, the unreliable narrator invites readers to engage more deeply with the story.
