The structural observation that skeptics and enthusiasts employ identical cognitive operations — mirror-image dissonance reduction, asymmetric scrutiny, and social reinforcement — producing opposite conclusions through the same mechanism.
The symmetry of dismissal names the analytical finding that, in the AI discourse, both camps engage in identical psychological processes operating in opposite directions. The senior engineer who dismisses evidence of AI capability and the enthusiast who dismisses evidence of AI limitation are not engaged in a productive argument about evidence. They are engaged in parallel dissonance-reduction exercises, each processing the same evidence through filters shaped not by the evidence itself but by the need to protect a prior investment.

The symmetry is not a "both sides" equivalence. It is a structural observation that explains why the discourse generates heat without producing light. The skeptic applies asymmetric scrutiny to dismiss capability evidence. The enthusiast applies asymmetric scrutiny to dismiss limitation evidence. Both employ selective attention, social reinforcement, and reinterpretation. Both experience their evaluations as honest assessment. Both produce systematically biased outputs invisible to
