Who Shapes What We Know? Algorithms, Echo Chambers, and the Fragmentation of Truth

Digital platforms have transformed how information circulates. Algorithms curate what billions of people see, often prioritizing content that reinforces existing beliefs, captures attention, and drives engagement. The result is a growing fragmentation of the public sphere. Instead of shared sources of information, audiences increasingly inhabit "echo chambers": personalized media environments where facts, narratives, and interpretations diverge dramatically. From rage-bait and viral misinformation to AI-generated content that spreads faster than it can be verified, the digital ecosystem is reshaping how societies produce and recognize knowledge. This panel explores whether common ground is still possible. When information is personalized and amplified by machines, how do we preserve shared standards of truth, scientific knowledge, and public debate?
