Absence as Information	Primary	Inference from Negative Evidence	The non-occurrence of an expected event is itself a positive signal.
Absence Of Evidence Vs Evidence Of Absence	Primary	Detection Power and Null Findings	A null finding becomes evidence against a claim only in proportion to how likely the search was to detect the claim had it been true.

Alienation	Primary	—	Disconnection from system.
Analogy	Also draws from	—	Transfer structure between domains.

Aspectual Individual	Primary	Ontology	Treating a single underlying entity, under a fixed role or aspect, as a distinct derived bearer of properties with its own narrower existence conditions.
Assumption	Primary	Logic and Reasoning	A proposition treated as true for the purposes of some reasoning without being currently demonstrated within it, forming the load-bearing layer between what is given and what is concluded.
Autonomy	Primary	Practical Philosophy	A unit's behavior is governed by its own internal rules or chosen reasons rather than external direction, defined by the inner-versus-outer authority asymmetry over a scoped domain.

Constraint	Also draws from	—	Limits possibilities to guide outcomes.
Continuity vs. Rupture	Also draws from	—	Gradual vs abrupt change.

Counterfactuals	Primary	—	Alternate hypothetical scenarios.
Criteria of Individuation	Primary	Metaphysics and Ontology	The rules a system fixes for what makes something one entity — when parts compose a single whole, when two presentations are the same entity, and which kind supplies a thing's persistence — together constituting its inventory of countable individuals.

Identity Test	Primary	Ontology Engineering	The rule that decides, in a given system, when two presentations refer to the same entity.

Pareto Efficiency	Also draws from	—	Optimal allocation.
Parsimony (Occam's Razor)	Primary	—	Prefer simplicity.
Past-State Contamination	Primary	Temporal Validity	Later information enters a reconstruction, estimate, or evaluation presented as valid for an earlier time, erasing the boundary between what was knowable then and what became available only afterward.

Rationality	Primary	—	Evaluate beliefs, choices or procedures by how coherently and responsively they connect evidence, reasons, aims, constraints and revision, under an explicit normative standard and information set.
Recognition Justice	Primary	Theories of Justice	Judge whether people, identities, experiences, and categories of harm are represented as intelligible and worthy of equal standing before an allocation or procedure is evaluated.
Reference class problem	Primary	—	Choose which relevant comparison class should govern a probability or generalization about one case when that case belongs to many classes with different rates.
Reference Standard Decay	Primary	Measurement and Evaluation	A measuring apparatus keeps scoring against a reference standard that has silently drifted, so its numbers stay stable while their meaning shifts.
Reflexivity (Self-Reference)	Also draws from	—	Self-referential systems.
Reframing	Primary	Hermeneutics	Hold an underlying situation, artifact, or event fixed while replacing the interpretive frame applied to it, so unchanged material acquires different meaning, salience, evaluation, or action implications.

Relation	Also draws from	—	Describes associations or dependencies.
Relevance Substitution	Primary	Informal Logic and Inference	A psychologically active but epistemically irrelevant signal is supplied in place of a relevant one, and the recipient updates on it blind to the substitution.

Statistical syllogism	Primary	—	Project a qualified proportion from a declared reference class onto a particular member as defeasible support for that member's having the attribute, with inferential strength inherited from the proportion and revised when a more relevant class or case-specific fact becomes available.
Streetlight Effect	Primary	Methodology of Inquiry	Search effort concentrates where evidence is easiest to observe rather than where the sought answer is most likely to lie, systematically substituting accessibility for relevance.
Suspension of judgment	Primary	—	Deliberately withhold commitment to a conclusion when the applicable grounds or decision threshold are not yet satisfied.

Theory	Primary	—	A coherent system of concepts and propositions that explains, organizes or predicts a domain through explicit relations and standards of support.
Thought Experiment	Primary	—	Test a claim or expose a concept by stipulating an imagined case, propagating its constraints, and treating the resulting fit, conflict, or consequence as evidence for revision.
Time	Also draws from	—	The dimension that orders events from earlier to later with measurable duration and an irreversible direction, providing the foundation for change, rate, and causality.
Tolerance Paradox	Primary	Political Philosophy	A system defined by an open principle must refuse that principle to elements that would destroy it, or be destroyed by its own openness.
Top-Down Perspectives	Also draws from	—	Centralized control.
Trade-offs	Also draws from	—	Balancing competing priorities.
Type–Token Distinction	Primary	Ontology and Semiotics	Separate a repeatable type from its numerically distinct tokens so shared properties attach once to the type while occurrence-specific identity, state, and history attach to each token.
Uncertainty	Primary	—	Incomplete knowledge.
Unfalsifiability	Primary	Philosophy of Science	No admissible observation can force rejection of a claim because it either forbids no possible outcome or can revise its refutation conditions after adverse evidence, leaving every result compatible with survival.
Uniformitarianism	Also draws from	—	Same processes over time.
Unity	Primary	Metaphysics	Unity is the substrate-neutral condition in which distinguishable constituents are related or organized as one effective, undivided whole at the scale relevant to an inquiry or action.
Unity Test	Primary	Mereology and Ontology	The rule that decides, in a given system, when a collection of parts counts as one whole rather than many.
Vagueness	Primary	Philosophy of LanguageLogic	Vagueness is indeterminacy in a term, predicate, or classification caused by application boundaries that do not yield a uniquely warranted verdict for borderline cases.
Validation	Also draws from	Experimental Design	Confirming that an artifact actually solves the intended problem in its real operational context, as distinct from confirming it was merely built to specification.
Vantage-Induced Omission	Primary	Observation Apparatus	An apparatus's structural vantage makes some regions of a landscape reachable and others constitutively invisible, so its output is mistaken for the landscape rather than the landscape-restricted-to-its-vantage.
Verification	Also draws from	—	Check that an object conforms to its specification via a defined procedure yielding evidence and a verdict.
Viewpoint	Primary	Observation and Access	A position fixes an access set, an occlusion set, and a bias profile.
Virtue Ethics	Primary	—	Focus on character traits.
Washout Failure	Primary	Experimental Design	When the same unit is observed under successive conditions, residual state from the first contaminates the second unless a gap long enough to dissipate it is built in, so underestimating that dissipation time reads the decaying tail of the old condition as an effect of the new one.
Zero-Force Null Baseline	Primary	Model Construction	A deliberately false idealised model with all named perturbing forces set to zero, whose empirical departures are read as attributable diagnoses of which forces operate and at what magnitude.
