filter bubble
/FIL-ter BUB-ul/ · noun · Hacker Culture · Origin: 2011
Definitions
A state of intellectual isolation resulting from algorithms that selectively curate the information a user sees based on their past behavior, location, and preferences. Unlike echo chambers, which are partly self-selected, filter bubbles are algorithmically imposed and often invisible to the user. Coined by Eli Pariser, the concept became central to debates about platform responsibility and algorithmic transparency.
In plain English: When websites and apps show you only what they think you want to see based on your past clicks, hiding everything else from you.
Example: "Two people Googled the same political topic and got completely different results. Filter bubbles in action."
