Facebook has affected both the quantity and quality of information available to people in significant ways: Quantity of Information
Facebook has dramatically increased the quantity of information accessible by providing a platform where individuals, organizations, and media can share news, opinions, and content widely and rapidly. Features like hashtags, sharing, and paid promotions have enabled information to go viral, making vast amounts of content available daily to millions of users

. Quality of Information
The quality of information on Facebook, however, has been negatively impacted. The platform has become a fertile ground for misinformation, fake news, clickbait, and sensationalized or biased content. Because anyone can post and share information without rigorous verification, users often encounter unreliable or misleading content. This proliferation of low-quality information has eroded trust and made it difficult for users to discern credible sources

. Algorithmic Effects and Echo Chambers
Facebook’s algorithms prioritize content aligned with users’ existing beliefs and interests, creating echo chambers that limit exposure to diverse perspectives. This reinforces polarization and reduces the quality of public discourse by narrowing the range of information and viewpoints users see

. Summary

• Facebook has greatly expanded the amount of information people can access.
• The ease of sharing has led to a surge in misinformation and low-quality content.
• Algorithms contribute to echo chambers, reducing exposure to varied viewpoints.
• The overall effect is an increase in quantity but a decline in the average quality and reliability of information on the platform

Thus, while Facebook has democratized information sharing and increased access, it has also complicated the information environment by mixing valuable content with misinformation and bias.
