Genuine competence in a narrow domain produces confident extrapolation into adjacent domains where the competence does not apply. The expertise is the mechanism of capture, not its absence. The deeper the tunnel, the more authoritative the mole sounds about what is above ground. The track record validates the wrong answer.

Field notes — behavioral signature

The Tunneling Mole does not perform certainty, it genuinely has it. Within the tunnel, the Mole is right. The tunnel is deep, the credentials are real, the track record within domain is sound. The problem is the surface, where the tunnel narrows to a point and the Mole emerges into terrain it cannot see. It speaks with the same authoritative confidence it has earned inside the tunnel. The tell is not uncertainty, the tell is the absence of it. The Mole has never needed to hedge inside the tunnel. It does not know that the surface requires hedging. It has never been wrong in the way that would teach it to notice the boundary.

Scale-invariant analogs
Individual The senior engineer whose architectural opinions dominate product decisions because no one can challenge the underlying technical authority.
Organizational The quant team whose risk models were trusted past their domain; the expertise that was real inside the tunnel destroyed the institution above it.
Constitutional The legal originalist whose interpretive framework is immune to evidence about consequences. Consequence is not within domain.
Diagnostic utility

The Tunneling Mole is the most difficult archetype to challenge because the challenge must be mounted against real competence. The challenger appears to be questioning credentials that genuinely exist. The correct intervention is domain mapping, not competence contestation: identifying precisely where the tunnel ends and the extrapolation begins, and holding that line. The Mole will resist because the domain boundary is invisible to it. That resistance is itself the confirmation.
