Psychological thrillers have become a significant part of contemporary literature by creating fear and tension through psychological uncertainty rather than relying solely on external and supernatural threats. This research examines how psychological thrillers engage readers through suspense, unreliable narration and psychological uncertainty. It argues that the genre shifts narrative tension towards internal psychological experiences and shapes the reader from passive recipient of information into an active participant in the construction of meaning. Drawing on narrative and reader-response theories, particularly the approaches of Raphael Baroni, Wolfgang Iser, and Wayne C. Booth, the study examines how incomplete information, anticipation, interpretive gaps and unreliable perspectives shape the reading experience. Literary examples including Colleen Hoover’s Verity, Alex Michaelides’s The Silent Patient, and Gillian Flynn’s Gone Girl demonstrate how these techniques encourage readers to form hypotheses, question information and revise previous interpretations. This research concludes that the literary significance of psychological thrillers lies not only in their ability to simply generate fear, but also in their ability to make uncertainty, interpretation, and reader participation central components of the narrative experience. In this way, psychological thrillers affect contemporary literature by strengthening the relationship between narrative uncertainty and active reader engagement.
