Overview

Algorithms are sets of rules that computers follow to make decisions, and they power the content you see on social media, search engines, and streaming platforms. This lesson explores how these invisible systems learn your preferences and decide what information appears in your feed, and why understanding them matters for your digital life.

Key Points

• Algorithms analyze your online behavior—clicks, likes, watch time—to predict what content you'll engage with
• Different platforms use different algorithms, so the same topic may appear very differently on YouTube versus TikTok versus Google
• Algorithms can create filter bubbles by showing you more of what you already like, potentially limiting exposure to diverse viewpoints
• Companies use algorithms to maximize engagement and advertising revenue, which shapes what gets promoted
• Being aware of how algorithms work helps you make more intentional choices about your media consumption

Why This Matters

Algorithms influence which news stories you see, whose opinions reach you, and how you spend your time online—affecting everything from your understanding of current events to your self-image. Learning how they work empowers you to be a more critical consumer of digital content and recognize when you're being influenced.
