Abstract A short, naturally occurring exchange about the conditions for consciousness in artificial systems exhibits a recurring rhetorical structure that this paper anatomises and names: Popper’s Cracker, a self-sealing five-step complex that protects unwarranted necessity claims from logical critique. The complex proceeds via (1) an N=1 necessity inference from observed correlation to substrate requirement; (2) a quiet re-typing of substrate-sufficient as substrate-necessary; (3) a falsifiability costume that wraps the necessity claim in pseudo-Popperian rhetoric; (4) a counter-model demand that reframes critique as obligation to ship a replacement theory; and (5) an epistemics/engineering conflation that treats logical objection as intellectual freeloading unless paired with positive construction. The five moves seal as a complex because each protects the others. The paper presents a single anonymised specimen, anatomises the complex, and identifies its kinship with broader pathologies of contemporary academic discourse, in particular a prevalent interpretation of peer-review practice that converts the publication system from a model-improvement mechanism into a model-preservation mechanism. A companion concept, the Teapot Fallacy, is introduced in a boxout and given full treatment in a forthcoming paper. The diagnosis offered here is methodological, not verdictive: identifying that a necessity claim has been argued via the complex does not establish that the claim is false, only that it has not been earned by the route taken.
