US social media misinformation study

Entities: Facebook · Meta Platforms · Instagram · United States · The Washington Post

Overview

Two July 2024 releases detailed a large‑scale experiment during the 2020 U.S. presidential election that cut exposure to repeatedly flagged untrustworthy sources on Facebook and Instagram by roughly 70 %. The feed adjustment did not change participants’ political attitudes or core beliefs, even among those previously exposed to the most misinformation. Both releases noted that a small minority of users (about 23 % on Facebook and 11 % on Instagram) generated the bulk of untrustworthy content, and that the median user saw only about 1.1 % of feed content from such sources on Facebook and 0.1 % on Instagram.

A July 2026 UC Berkeley study, published in *Science Advances*, replicated the experiment and confirmed the same reduction in exposure and the same lack of measurable impact on political beliefs, emphasizing that algorithmic tweaks alone cannot shift deeply held views. An August 2026 Meta‑conducted study of nearly 16,000 U.S. users found that removing content flagged by third‑party fact‑checkers also produced essentially zero change in voter attitudes. Together, the findings reinforce the conclusion that combating political polarization will require interventions beyond simple feed adjustments.
