Beyond the Scroll: How Social Media Algorithms Shape Your Reality

Social media algorithms curate your feed by predicting what content will maximize your engagement, using techniques that find users similar to you or content similar to what you've already liked. A key method called cosine similarity measures the conceptual "angle" between items, recommending new content that points in the same direction as your previous interactions, whether by topic or emotional response. These systems give immense power to your most recent actions through "recency weighting," where a click from three minutes ago is valued far more than one from three days ago. Consequently, just a few curious clicks on a new subject can cause the algorithm to instantly flood your feed with related material, rapidly creating a powerful filter bubble.
