Stage Rationality

A performative form of rationality where the actor claims to be rational while controlling the conditions that define rationality, ensuring that their own behavior appears rational and their opponent’s appears irrational. Stage rationality is often deployed in online debates, where one side insists on “logic” and “evidence” but refuses to examine their own assumptions. The stage rationalist moves goalposts, changes definitions, and demands impossible proof—all while maintaining the appearance of dispassionate reason. It is rationality as a weapon, not a method.

Example: “He called himself a rationalist, but every time she provided evidence, he changed what he meant by ‘evidence’—stage rationality, using the language of reason to avoid actual reasoning.”

Post hoc rationalization

Don't care bitch you don't hage a right to do it EITHER WAY you fucking mongrel. You need to take your own advice and humble yourselves OR get your kids murdered more frequently until you learn to stop infesting people's lives like the cockroaches you are.

Hym "You're trying this as post hoc rationalization and it isn't going to work. 1 or 0 fuck-face. Choose."

Hard Problem of Rationality

The paradox that the tool we use to evaluate truth—rationality—cannot be justified using purely rational means without circular reasoning. Why should we be rational? Because it's effective? That's a pragmatic, not rational, argument. Rationality rests on axioms (like "the world is consistent") that must be assumed, not proven. The hard problem is that rationality is the judge, jury, and executioner of thought, but it can't put itself on trial without presupposing its own validity.

Example: "He tried to use pure rationality to convince his friend to be rational. 'You should value logic because... it's logical?' He hit the hard problem of rationality: the foundation of reason isn't a brick; it's a turtle floating in mid-air, and asking 'why?' just makes it fall."

Self-Serving Rationality

The performance of being coldly, dispassionately rational in situations where that rationality conveniently aligns with your desires, while abandoning that rigor in situations where it doesn't. You'll do a complex cost-benefit analysis to prove why you should buy the new gadget, but will use a gut feeling to dismiss the same analysis when it suggests you should apologize to a friend you wronged.

Example: "Her self-serving rationality was transparent: she spent three hours comparing CPU benchmarks to justify the expensive laptop she wanted for gaming ('It's the rational choice for long-term value!'). Yet, when her partner suggested comparing grocery prices to save money, it was suddenly 'an exhausting over-optimization of life.' Rationality was her servant, not her master."

Theory of Constructed Rationality

The insight that what counts as "rational" behavior is defined by cultural and historical context. Maximizing personal profit is "rational" in neoliberal economics. Sacrificing oneself for one's community is "rational" in a honor-based society. Rationality is not a universal calculator in the brain; it's a set of culturally constructed goals and acceptable means that we learn and perform.

Example: "My boss said turning down a promotion to care for my dad was 'irrational.' My family said it was the only honorable choice. The Theory of Constructed Rationality explains the clash: we were using different construction manuals. His manual defined rationality as individual career maximization. Mine defined it as fulfilling familial duty. Neither is 'natural'; both are learned scripts for sensible action."

Fallacy of Rationalization

The psychological and rhetorical maneuver of constructing superficially reasonable-sounding excuses or justifications for regressive, harmful, or morally reprehensible positions, particularly those that advocate for a return to oppressive historical systems or the acceptance of civilizational backsliding. This fallacy uses the language of reason—practicality, economic benefit, cultural tradition, or flawed historical analogy—to dress up a conclusion rooted in prejudice, fear, or power dynamics. It's not true reasoning; it's a post-hoc salvage operation for an indefensible stance, seeking to retrofit logic onto bigotry or oppression. The tell is that the "rationale" always serves to excuse suffering or inequality.

Example: Arguing for the return of exploitative child labor by saying "It teaches them discipline and helps poor families earn money" commits the Fallacy of Rationalization. It uses a veneer of pragmatic economic concern to justify a brutal practice society rightly outlawed. Similarly, defending colonial atrocities with "It brought infrastructure and modern government" rationalizes genocide and plunder by cherry-picking secondary outcomes while ignoring the primary moral catastrophe.

Theory of Rational Social Control

Closely related to logical control, this focuses on the application of "rationality" as a governing principle for social organization and individual behavior. It examines systems (like bureaucracies or economic models) that claim to optimize human activity based on cost-benefit analysis and instrumental reason, often at the expense of human values, ethics, and spontaneity. Control is achieved by making everything subject to a cold calculus of efficiency.

Theory of Rational Social Control Example: A university replaces small, discussion-based humanities seminars with massive, standardized online lectures graded by AI. Administrators justify this as the "rational" choice—it's scalable and cost-effective. This rational social control prioritizes metric-based efficiency over the unquantifiable educational value of personal mentorship and dynamic debate, reshaping the institution's human purpose to fit a sterile, calculable model.
