Echo chamber vs filter bubble

echo chamber

An echo chamber is driven by social pressure and community enforcement of a single view.

VS

filter-bubble

A filter bubble is driven by algorithms quietly limiting what you see without any community pressure.

Origin and context

Borrowed from acoustics, where a chamber that reflects sound creates amplification. Applied to media and politics by researchers studying how closed information environments reinforce belief. Became mainstream internet vocabulary around 2016 during political social media debates.
