What is epistemic bubbles?

Example: You read three articles about declining economic conditions. They confirm a concern you already held. Now you are primed — your next search query includes words like 'recession,' 'downturn,' 'market crash.' The search engine returns results matching those terms. You read them. Your concern deepens. Your next conversation references these articles, and the person you are talking to sends you two more. Within a week, your information environment has reorganized itself around a single narrative — not because the evidence is overwhelming, but because your consumption pattern generated a feedback loop that systematically amplified one signal and suppressed everything else.

This concept is part of Feedback Loops in the How to Think curriculum.
