At lunch someone says the office may move floors. Nobody has an official memo yet, but the rumor is already traveling. A rumor is not simply any false statement. It is information circulating without authoritative verification while its tru
What you’ll learn
- A Rumor Is Built for UncertaintyDefine rumor and explain how ambiguity, importance, and anxiety create reasons to circulate unverified information.Rumors are informal responses to information gaps; their circulation reflects relevance and uncertainty, not proof of truth or intentional lying.
- Emotion Supplies MomentumExplain how emotional and moral relevance can increase attention and sharing without treating emotion as a truth test.Arousal can make a claim more noticeable, memorable, and socially actionable while leaving its factual status unresolved.
- Repetition Creates FamiliarityDescribe the illusory truth pathway from repeated exposure to perceived accuracy and sharing.Repeated claims become easier to process, and that fluency can be mistaken for evidence, especially when decisive knowledge is absent.
- Networks Multiply ReachExplain how branching paths, bridges, homophily, and echo chambers affect rumor reach.Networks can multiply exposure and create apparent consensus without adding independent evidence to the claim.
- Corrections Face Different PhysicsCompare rumor spread with correction timing, replacement explanations, source trust, and attention.Corrections can work, but they must compete with a familiar and distributed story; timing, trust, and a usable alternative account improve the odds.
Questions this course answers
Why can an uncertain claim spread even before anyone knows whether it is true?
Rumors can function as informal attempts to understand an ambiguous, important situation; transmission does not prove verification or deception.
Put the repetition pathway in its most plausible order.
Repeated exposure can increase familiarity and fluency, which may bias perceived accuracy and downstream sharing.
Why can a network amplify a rumor without making it more true?
Network structure changes how many people encounter a claim and how often they see it, not whether the underlying claim is supported.
Match each correction feature to what it changes.
Corrections work through several bottlenecks: timing, memory structure, credibility, and attention.
Why is a correction not guaranteed to spread as quickly as the rumor it addresses?
Corrections can improve belief accuracy, but their reach and effect depend on timing, source trust, explanation quality, attention, and the network through which they travel.
