The short answer
The echo chamber is built by you — active exclusion of dissenting voices. The filter bubble is built by the algorithm. Echo chambers are harder to escape precisely because someone chose the walls, and choosing them again is easy.
Side by side
| Aspect | Echo chamber | Filter bubble |
|---|---|---|
| Built by | You | The algorithm |
| Visible to you | Yes | No |
| Fixed by exposure | Can backfire | Sometimes |
| Requires effort | Yes | No |
What each one means
An information environment, usually one you curate yourself, where only agreeing views reach you — beliefs amplified by repetition rather than tested. Literally, an echo chamber is a room built to produce echoes, and the studio effect that imitates one.
