We cannot push a hand through a wall because it is solid.
Likewise, there are structures of failure through which no further reasoning can pass—not because reason is weak, but because it has reached its limit surface.
Structural tragedy begins where rational admissibility ends.
Beyond that wall, there is no mistake to correct, no belief to update, no incentive to realign.
There is only loss that remains even if everyone reasons correctly.
We study what lies beyond the wall.
This is a normative research lab.
Its aim is not optimization, persuasion, or repair, but diagnosis: to identify failures that persist under ideal rationality.
Using cognitive geometry, we study how values, beliefs, interpretations, and admissibility constraints jointly determine what outcomes are possible—and where tragedy is structurally unavoidable.
We do not ask how agents should reason better.
We ask where better reasoning no longer helps, and what still matters there.
