Filter bubble
The personalized information environment created by algorithms that learn what you click and show you more of it.
Term coined by Eli Pariser in 2011. Filter bubbles are the algorithmic mechanism that produces and reinforces echo chambers. They differ from voluntary echo chambers because the user typically doesn't know what's being filtered out. Even users who actively try to consume diverse sources find that the algorithm narrows their default feed. Mitigations: use RSS readers or aggregators (where YOU pick the inputs), follow accounts you disagree with, and once a week deliberately look at someone else's feed to see what their algorithm shows. See also: echo chamber.
