Social Media and Information

Algorithms, echo chambers, information warfare, and your feed.

Social media platforms are not neutral pipes for information. They are attention markets — their revenue depends on keeping you engaged, and their algorithms are optimized for exactly that.

What the algorithm rewards:

  • Emotional content — Posts that provoke outrage, fear, or moral indignation get more engagement and therefore more distribution. A 2021 study published in Science found that each moral-emotional word in a tweet increased its retweet rate by approximately 20%.
  • Conflict — Disagreement drives comments. The algorithm reads comments as engagement and boosts the post.
  • Speed over accuracy — Breaking news, rumors, and hot takes spread faster than careful reporting. A 2018 MIT study found that false news stories on Twitter reached 1,500 people about six times faster than true stories.
  • Personalization — Your feed is curated based on your past behavior. Over time, this creates a filter bubble — you see more of what you already agree with and less of what challenges you.
