Hyperrationalism

The ideological belief that reason and logic constitute a supreme, transcendent authority above all other human faculties—emotion, intuition, tradition, art. It is a form of rational fundamentalism that seeks to remake the messy human world in the clean image of deductive logic, viewing any resistance as irrationality to be corrected.

Example: A city planner who proposes bulldozing a historic, organically grown neighborhood to replace it with a geometrically perfect grid of identical housing units because "it is the most logically efficient use of space." Hyperrationalism values abstract optimization over lived community, culture, and beauty.

Hyperrationalism Bias

The fallacy that pure reason is the only valid tool to dissect any subject, including profound moral evils. It assumes one can and should debate the "logic" of racism, the "economic efficiency" of slavery, or the "rational merits" of genocide in a detached, clinical way, as if they were abstract puzzles. This bias mistakes the application of rationality for moral intelligence, and often serves to sanitize horror.

Example: A forum hosting a "rational debate" on the Holocaust where participants are instructed to "set aside emotions" and argue only from "statistical and strategic premises" about Nazi efficiency. The hyperrationalism bias creates a morally monstrous space where the form of rational discourse is used to eviscerate its ethical content.

Hyperrationalism

The worldview that elevates rationality above all other human faculties—treating reason as not just a tool but the tool, the only reliable guide to truth, value, and action. Hyperrationalism is the faith of those who trust logic more than experience, argument more than intuition, proof more than feeling. It's the philosophy of the engineer who can't understand poetry, the scientist who dismisses wisdom, the debater who wins arguments but loses friends. Hyperrationalism produces clarity about narrow questions and blindness about broad ones. It's powerful within its domain and useless outside it—but hyperrationalists don't recognize the boundary.

Example: "He'd solved everything with logic his whole life—math, science, engineering, puzzles. Then he tried to solve his marriage the same way. Hyperrationalism had no answer for why she was unhappy, no equation for love, no proof for trust. He had all the right tools and no idea what to build. Reason had failed him because he'd asked it to do what it can't: feel."

Hyperfixation 

Used commonly by those with autism or ADHD, refers to an extreme and overwhelming interest in a game, show, book, movie, or other piece of media. Mentions of such media can cause intense euphoria and almost "awaken" a neurodivergent person.

These fixations may get to dangerous or intrusive proportions, where the fixator can only think or talk about their interests. They may even neglect their health to engage in it.

Hyperfixations may die out with time, turn on and off, or remain prominent for a majority of a person's life.

I gave this game a try and I haven't stopped thinking about it for a week straight. I hope this isn't another hyperfixation.

Metadebate Hyperrationalization

When a debate ceases to be about the original topic and becomes a self-referential argument about the rules of rational engagement themselves. It's a retreat into meta-discussion about burden of proof, logical fallacies, or epistemological frameworks, as a tactic to avoid substantive engagement on the (often uncomfortable) primary issue.

Example: When challenged on a political claim, a participant shifts the entire conversation to: "You're using a postmodernist epistemology, which is inherently irrational. We must first debate whether your framework for knowing is valid." This metadebate hyperrationalization is an escape hatch from the actual debate into an infinite regress about debating.

Fallacy of Hyperrationalization

The practice of applying rational argumentation to literally everything—including topics that are fundamentally beyond the reach of reason, or that should be beyond the pale of acceptable debate. Hyperrationalization treats all questions as equally debatable, all positions as equally worthy of engagement, all claims as requiring the same rational scrutiny. It's the fallacy that leads people to "debate" whether genocide is wrong, whether slavery should be reinstated, whether racism has merits—as if these were open questions rather than settled horrors. Hyperrationalization mistakes the form of reason for its substance, treating the act of arguing as inherently virtuous regardless of what's being argued. It's reason as performance, rationality as spectacle.

Example: "The panel was titled 'Debating the Merits of Slavery: A Rational Approach.' The Fallacy of Hyperrationalization had turned atrocity into abstraction, evil into exercise. There was nothing to debate; there was only horror. But hyperrationalization demanded that all questions be open, all positions be considered, all arguments be heard—even those that should never be spoken."
