🧠 How Social Media Algorithms Really Work
Unlike the movie recommender (which uses your explicit ratings), social media algorithms
track implicit behavioral signals:
Signals Tracked:
• Dwell Time: How long you look at a post (even without interacting)
• Mouse Movement: Did your cursor hover over the post?
• Scroll Speed: Did you slow down or skip past quickly?
• Likes & Clicks: Explicit engagement (worth more points)
• Skips: Actively skipping content sends a negative signal
The Algorithm's Goal: Maximize engagement (time spent, interactions), NOT your satisfaction
or wellbeing. This creates a "filter bubble" where you see more of what keeps you scrolling, even if
it's not what you consciously want.
💡 Try This: Notice how spending just 10 seconds looking at a post (even without liking it)
teaches the algorithm that you want more similar content. Your behavior speaks louder than your intentions!
⚠️ Watch For: The "rabbit hole" effect - engaging with one controversial or emotional
post can quickly shift your entire feed toward more extreme content, because those posts generate high engagement.
