echo chamber

Syllable breakdown

Dictionary meaning

a media or social environment in which a person encounters only views and opinions that reinforce their existing beliefs, because the information sources, peer networks, and platform algorithms they rely on filter out contradictory perspectives; the echo chamber metaphor captures the way beliefs amplify and intensify when they bounce repeatedly within a closed space without encountering resistance; related to but distinct from the filter bubble — which is algorithmically imposed — an echo chamber may also arise from voluntary choices about which communities, media, and social networks to participate in; echo chambers are implicated in political polarisation, the spread of misinformation, and the difficulty of achieving democratic deliberation across ideological lines
