echo chamber

Opinion feedback loop

An echo chamber is an environment where people encounter only opinions and information that reinforce their existing beliefs.

The metaphor comes from acoustic echo chambers, where sound reflects back unchanged.

In discussions of media and politics, echo chamber describes how social media algorithms and selective news consumption create spaces where dissenting views rarely penetrate: Twitter has become an echo chamber for political extremists.

The term usually carries criticism—suggesting intellectual isolation rather than genuine discourse.
