Rationality Blind Spot

The failure to recognize when your own commitment to being "rational" has itself become an irrational, identity-driven posture. It's the inability to see that your hyper-rational, emotion-dismissing approach might be blinding you to important factors like empathy, ethics, or social context, and that this inflexibility is itself a form of bias. You're so busy looking for emotional bias in others, you don't see the cold, calculating bias in yourself.
Example: "He proposed solving the budget deficit by auctioning off national parks, citing pure economic rationality. When people called it heartless, he accused them of emotional thinking. His rationality blind spot prevented him from seeing that his model completely ignored the non-monetary value of heritage, ecology, and public well-being—a massive irrational omission."

Sweeping Rationality

The imperialistic overreach of a particular model of rationality (often hyper-logical, quantitative, or scientistic) into domains where it is ill-suited, such as art, love, spirituality, or tradition. It sweeps away other ways of knowing by declaring them "irrational."
Example: "His sweeping rationality killed the poetry reading. 'A sunset isn't "beautiful,"' he said. 'It's just Rayleigh scattering. And your poem about loss is just a dopamine deficit triggered by memory recall.' He swept the entire room's experience into the narrow bin of reductive materialism."

Special Rationality

A tailored system of reasoning used to justify actions or beliefs in a specific, often high-stakes or identity-linked, context. This rationality may include unique axioms or weightings of evidence that would not pass muster in general discourse but feel completely compelling within the special frame.
Example: "The cult leader's special rationality was airtight to his followers: 'The spacecraft is invisible to non-believers because their vibrations are low. The fact you can't see it with telescopes proves you need our cleansing ritual.' Within the special framework, the lack of evidence became the strongest evidence."

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."

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.”

Spectral Variables (Rationality)

The hidden factors that shape what counts as "rational" in a given context, influencing judgments without appearing in conscious deliberation. These include emotional states (fear makes certain options look irrational), social pressures (what your peers would think), embodied cognition (how hungry or tired you are), and cultural narratives (stories about what rational people do). Spectral variables in rationality explain why the same person can make brilliant decisions in one context and terrible ones in another—not because their reasoning ability changed, but because the ghosts haunting their rationality shifted. True wisdom involves learning to sense these ghosts before they sense you.
Spectral Variables (Rationality) "I thought I was making a purely rational career decision. Then therapy revealed the Spectral Variables: I was still trying to impress my dad, who's been dead for five years. Rationality is never just rationality—it's haunted by everything you haven't dealt with."

Sociology of Reason and Rationality Literacy

The ability to analyze how social structures, institutions, and power relations shape what counts as reasonable. It draws on the sociology of knowledge and science to show that standards of rationality vary across social contexts, are enforced by professional communities, and can serve to exclude certain groups. This literacy reveals that who gets to define “rational” is itself a question of power.
Example: “Her sociology of reason and rationality literacy helped her expose how the labelirrational’ was applied to protest movements—not because their demands lacked reason, but because their forms of reasoning didn’t fit the elite institutions where ‘rational’ was defined.”
