The Fragmentation of Objective Truth
Personalized feeds can separate audiences without making truth itself merely subjective.
The Mechanism: Recommendation systems select content based on signals such as user activity and predicted relevance. They can create distinct information environments, but polarization also reflects political identity, media institutions, and offline relationships.
The Philosophical Pivot: Disagreement about facts can weaken trust in shared methods of checking them. The problem is not that truth disappears, but that people may no longer agree on how evidence should be evaluated.
The Horizon: Public institutions need transparent corrections, trustworthy journalism, and spaces where disagreement can be tested against common records. No single platform can restore consensus by itself.
Claims of objective truth can be used to silence marginalized testimony, while pure relativism can protect powerful falsehoods. A better approach keeps evidence open to challenge and revision.
Shared reality is maintained through practices of verification, not merely assumed because people inhabit the same network.
Truth does not vanish when people disagree, but the road back to evidence can be blocked.
When I meet a claim that contradicts my group, what shared evidence would I accept as a reason to revise my view?
