What is "algorithms," and how do they shape what we see online?

Algorithms are sets of rules used by platforms like social media, search engines, and streaming services to decide what content to show you. They track your behavior—what you like, share, or watch—and use that data to serve you more of what they think you’ll enjoy. While this can make your online experience feel personalized, it also means you’re more likely to stay in a “filter bubble,” seeing only content that aligns with your preferences and beliefs. This can limit exposure to diverse perspectives and sometimes even amplify misinformation, making it a double-edged sword in our digital lives.
