Criteria for empirical theories of consciousness should focus on the explanatory power of mechanisms, not on functional equivalence.

A functionalist criterion for arbitrating between theories of consciousness is not theory-neutral because it focuses on functional equivalence between systems. Empirical theories of consciousness are mechanistic rather than functionalist, so such criteria are not helpful for arbitration.

Abstract

Doerig and colleagues put forward the notion that we need hard and theory-neutral criteria by which to arbitrate between empirical (mechanistic) theories of consciousness. However, most of the criteria that they propose are not theory neutral because they focus on functional equivalence between systems. Because empirical theories of consciousness are mechanistic rather than functionalist, we think these criteria are not helpful when arbitrating between them.
