“The term “Mécroyance” is deliberately spelled differently from the French word “mécréance.””

The spelling difference appears intentional. “Mécréance” is the established French word, while “mécroyance” is presented as a deliberately formed noun derived from “mécroire.” However, the supporting account describes a distinct coinage rather than explicitly stating that an existing word was respelled.

“The concept of 'mécroyance' is defined as a structural cognitive condition in which an individual or system sincerely adheres to a coherent interpretive framework based on erroneous, incomplete, or insufficiently questioned premises, without intent to deceive or reject the truth, and this condition can be modeled by the formula M = (G + N) − D, where M is mécroyance, G is articulated knowledge (gnōsis), N is integrated experience (nous), and D is stabilized certainty (doxa).”

No credible source defines "mécroyance" as a structural cognitive condition or attests the formula M = (G + N) − D. Authoritative French dictionaries (CNRTL, Littré) define "mécréance" as religious unbelief or infidelity. While psychology literature acknowledges sincerely held but erroneous belief systems, none uses this term or equation. The claim presents an unattested, fabricated concept as though it were an established definition.
