The method of computation resembles authority in that the AI system speaks with grammatical precision, logical structure, and tonal measure — the voice of apparent expertise. But unlike classical authority, the AI has no institutional standing, no professional reputation, no social sanctions to deploy. Its authority is purely presentational, the authority of a confident polished voice, and is therefore simultaneously more pervasive and more difficult to resist.
It resembles the a priori method in that the AI's output tends to confirm what seems reasonable within the cultural frameworks encoded in its training data. The model is trained on the accumulated textual output of a particular civilization at a particular moment, and its statistical regularities reflect prevailing assumptions. Its output tends to align with the cultural common sense of the society that produced its training data — dressed in the rhetoric of independent analysis.
It resembles tenacity when configured to confirm existing beliefs. The human asks leading questions, accepts confirming outputs, dismisses disconfirming ones. The AI becomes an instrument of tenacious belief-fixation at industrial scale, producing articulate supporting arguments with fluency the human alone could never achieve.
What the method lacks is the four features of the method of science: genuine confrontation with experience, capacity for self-correction, the irritation of doubt, and commitment to truth as a normative ideal. The AI does not confront experience; it processes training data. It does not self-correct; new inputs produce new outputs without normative revision of prior ones. It does not experience doubt; its outputs carry no signal of their own uncertainty. It has no normative commitments; its outputs are shaped by optimization objectives, not by care for correspondence with reality.
The concept is the Peirce volume's original extension of Peirce's taxonomy to cover a category of belief-fixation that did not exist in 1877 but has become, in the past decade, a dominant mode of settling belief across the knowledge economy.
The analysis draws on both Peirce's classical framework and contemporary empirical research in cognitive psychology on how presentation quality affects perceived credibility.
Fifth method. Belief-fixation through fluent, confident AI output — a category Peirce did not anticipate but his framework diagnoses precisely.
Hybrid pathology. Combines features of authority, a priori, and tenacity without being reducible to any.
Lacks self-correction. Missing the four features that make the method of science uniquely reliable: experience, self-correction, doubt, and commitment to truth.
Invisible substitution. The output of the method of computation can be superficially indistinguishable from the output of the method of science, which is what makes the substitution dangerous.
