Echo chamber
An information environment in which a person primarily encounters views and facts that match their existing beliefs.
Echo chambers can be deliberate (subscribing only to outlets you agree with) or algorithmic (the social feed learns what keeps you engaged and shows more of it). Effects: false consensus ("everyone I know agrees"), reduced calibration on contested topics, hostility toward out-groups whose actual arguments you never encounter. The cure is structural: deliberately read at least one source outside your default lane. Prism Cross-Platform Snapshot is designed for this — one search, every platform's framing visible at once. See also: filter bubble, blindspot.
