Rational Projection

A cognitive bias where one projects one's own standards of rationality onto others—assuming that everyone should reason the same way, value the same things, reach the same conclusions from the same evidence, and that those who don't are simply irrational. Rational projection operates when someone says "any rational person would agree" about matters where reasonable people differ; when they dismiss alternative values as irrational rather than differently valued; when they cannot recognize that rationality itself is culturally and historically variable. The projection lies in mistaking one's own rationality for Rationality itself—assuming that the way one thinks is simply the way thinking should be done. It's a form of cognitive imperialism, imposing one's own standards while remaining blind to their specificity.

Example: "He insisted that any rational person would support his policy preferences—rational projection, assuming his values were universal reason rather than particular commitments."

Rational Contextualism

A philosophical framework holding that rationality is context-dependent—that what counts as rational reasoning, good reasons, and appropriate justification varies with the context of inquiry, the domain of application, and the purposes of the reasoner. Rational contextualism challenges the idea of a single, universal standard of rationality. What is rational in a scientific context may not be in a moral context; what is rational in everyday life may not be in a courtroom. Contextualism doesn't abandon reason; it recognizes that reason is always reason-in-context. It demands that we attend to the contexts that shape what counts as rational.

Example: "His rational contextualism meant he didn't demand scientific standards of rationality for personal decisions. It was rational to choose a partner based on love, even if it didn't follow the rules of decision theory."

Rational Multicontextualism

A philosophical framework holding that rationality is shaped by multiple, irreducible contexts—scientific, moral, practical, cultural, personal—that interact to constitute what rationality is and does. A rational decision in one context may be irrational in another; what counts as good reasoning depends on the context of the problem, the context of available information, the context of the community, the context of the reasoner's values. Rational multicontextualism insists that no single context exhausts the nature of rationality and that understanding reason requires attending to this contextual multiplicity.

Example: "Her rational multicontextualism meant she studied medical decision-making not just through clinical guidelines, but also through patient values, cultural beliefs, institutional constraints, and ethical considerations—all of which shaped what counted as rational."

Rational Perspectivism

A philosophical framework holding that rationality is always from a perspective—that what counts as good reasons depends on the theoretical framework, cultural background, and practical purposes from which one reasons. Rational perspectivism rejects the idea of a single, universal rationality that transcends all perspectives. What is rational from a utilitarian perspective may not be from a deontological perspective; what is rational in one culture may be different in another. Perspectivism doesn't make reason relative; it recognizes that reason is always reason-from-a-perspective and that different perspectives can be rational in their own domains.

Example: "His rational perspectivism meant he could accept that different cultures had different standards of rationality—not because any standard was arbitrary, but because rationality was always about reasoning well in a context, and contexts differed."

Rational Multiperspectivism

A philosophical framework holding that genuine understanding requires multiple, irreducible rational perspectives—that no single account of rationality captures the fullness of reason and that different rational traditions (utilitarian, deontological, virtue-based, pragmatic) reveal dimensions that others miss. Rational multiperspectivism rejects the reduction of rationality to any one framework. It insists that ethical reasoning, scientific reasoning, everyday reasoning, and spiritual reasoning are all rational in their own ways, and that wisdom requires moving between them.

Example: "Her rational multiperspectivism meant she drew on utilitarian calculation, deontological principles, virtue ethics, and pragmatic considerations in her ethical work—not because she was indecisive, but because ethical problems were complex enough to require multiple rational perspectives."

Rational Recursion

The application of rational standards to rationality itself—asking whether one’s standards of rationality are themselves rational, and whether that meta‑standard is rational, leading to an infinite chain. Rational recursion is often used to challenge foundationalist claims in epistemology, showing that any justification for reason must either be circular, regressive, or dogmatic. In practical discourse, it appears when someone demands a rational justification for trusting reason, leading to a paradox.

Example: “He demanded a rational proof that rationality is reliable. She noted that any such proof would already assume rationality. Rational recursion: the impossibility of fully grounding reason without circularity.”

Rational Generativity

The ability of rational thought to produce new ideas, solutions, and frameworks from existing principles through analogical extension, recombination, and creative inference. Rational generativity is what distinguishes creative reasoning from mere rote logic; it enables scientists to formulate hypotheses, lawyers to construct novel arguments, and everyday people to improvise solutions. Without generativity, reason would be merely computational; with it, reason becomes productive.

Example: “The engineer’s rational generativity turned basic physics into a new bridge design—not just applying rules, but generating new possibilities from them.”
