Authors use unreliable narrators to challenge readers' perceptions and assumptions by presenting a narrative that is skewed or distorted by the narrator's biases, limited perspective, or intentional deceit. This can lead readers to question the truthfulness of the story being told and forces them to critically analyze the events, characters, and themes in the text. By creating doubt and ambiguity through an unreliable narrator, authors encourage readers to engage actively with the text, consider multiple interpretations, and ultimately come to their own conclusions about the story.
