Argumentum Ad Cognitionem

A logical fallacy where one dismisses an argument by claiming the opponent is delusional, cognitively impaired, or using ableist slurs to describe their mental state. The fallacy lies in treating cognitive capacity as a refutation of claims, as if being confused or mistaken in some areas invalidates everything someone says. This fallacy is particularly toxic because it weaponizes genuine cognitive differences and disabilities, using them as cudgels to dismiss dissent. "You're delusional" becomes a way of saying "I don't need to engage with your points" while performing the appearance of having refuted them. It's argument by ableism, not by reason.

Example: "She presented documented evidence of corruption, and his response was simply 'you're delusional.' Argumentum Ad Cognitionem: using accusations of cognitive failure to avoid confronting uncomfortable facts."

Argumentum Ad Intelligentiam

A logical fallacy where one dismisses an argument by attacking the opponent's intelligence, typically with variations of "you're stupid." The fallacy lies in treating IQ as a proxy for correctness, as if being less intelligent automatically makes someone wrong about a particular claim. "You're too dumb to understand" becomes a way of avoiding engagement, a preemptive dismissal that requires no evidence and addresses no substance. This fallacy is the lazy debater's favorite: rather than explain why a position is wrong, simply assert that only stupid people would hold it, thereby positioning oneself as intelligent without demonstrating any actual intelligence through reasoned argument.

Example: "He couldn't explain why her economic analysis was flawed, so he just called her stupid. Argumentum Ad Intelligentiam: when you can't win the argument, attack the arguer's IQ."

Argumentum Ad Sanitatem

A logical fallacy where one dismisses an argument by claiming the opponent needs psychological or psychiatric help, rather than engaging with the substance of their position. The fallacy lies in treating mental health status as a refutation of claims, as if being in psychological distress automatically invalidates what someone says. "You need help" becomes a conversation-ender, a way of dismissing uncomfortable ideas by pathologizing the person who holds them. This fallacy is particularly insidious because it weaponizes genuine mental health concerns—using the stigma surrounding psychological distress to silence dissent, avoid difficult conversations, and position oneself as the sane, reasonable party without actually addressing any arguments. It's argument by diagnosis, not by reason.

Example: "When she raised legitimate concerns about workplace conditions, her manager didn't address a single point—just said 'you need psychiatric help.' Argumentum Ad Sanitatem: using the language of mental health to avoid engaging with substance."

Legit Decolonial Theory

A framework arguing for the legitimacy of decolonial approaches in specific domains—particularly in understanding how colonial power structures persist after formal independence and how they might be dismantled. Legit decolonial theory holds that colonialism didn't end; it transformed, and understanding this transformation requires tools that mainstream Western thought doesn't provide. It draws on the intellectual traditions of the colonized not as ethnographic curiosities but as serious theoretical resources—ways of knowing that reveal what colonial power has hidden. Legit decolonial theory is decolonial thought as necessary supplement to Western critical traditions, not replacement for them but corrective to their blind spots. It asks not just "what is true?" but "whose truth has been suppressed, and what does recovering it reveal?"

Example: "He used decolonial theory to analyze how development policies continue colonial patterns—not to reject all development, but to ask why it always serves the same interests. Legit Decolonial Theory: critique as clarification, not condemnation."

Valid Decolonial Theory

A theoretical framework that distinguishes between pathological forms of decolonial thought (dogmatic anti-Westernism, rejection of all universal standards, performative radicalism, intellectual obscurantism) and valid forms that offer genuine insight into coloniality and liberation. Valid decolonial theory analyzes how colonialism structured not just politics and economics but knowledge, culture, and consciousness itself—and argues for the decolonization of all these domains. It draws on Indigenous, African, Latin American, and other non-Western intellectual traditions not as alternatives to rigor but as sources of rigor themselves, not as rejections of truth but as expansions of what truth can mean. Valid decolonial theory doesn't claim that Western thought is worthless; it claims that Western thought has been hegemonic, that this hegemony has impoverished everyone, and that genuine understanding requires centering perspectives that have been marginalized. It's decolonial theory as intellectual liberation, not intellectual closure.

Example: "Her work didn't reject science—it asked why Indigenous knowledge systems aren't treated as science. Valid Decolonial Theory: not dismissing Western knowledge, but asking why it's the only kind that counts."

Critical Theory of Legal Systems

A framework that applies critical theory's tools to understanding legal systems as whole—not just individual laws or cases but the structure, ideology, and operation of law as a social institution. The critical theory of legal systems examines how legal systems produce legitimacy for dominant orders, how legal reasoning conceals political choices, how legal institutions reproduce inequality while claiming neutrality. It draws on systems theory, critical legal studies, and social theory to understand law as a complex, self-reproducing system that both reflects and shapes social power—a site where domination is both practiced and hidden, both resisted and reinforced.

Example: "His analysis showed how the legal system's claim to autonomy—its separation from politics—actually makes it more effective at serving power. Critical Theory of Legal Systems: law as a system that legitimizes by seeming separate."

Critical Theory of Economics

A framework that turns critical theory's tools onto the discipline of economics itself—examining how economics as a field produces knowledge, serves power, and shapes reality. The critical theory of economics asks not just about economic phenomena but about economics: who gets to be an economist, what counts as economic knowledge, how economic models shape the reality they claim to describe, how the discipline's pretensions to science mask its service to power. It draws on history of economic thought, sociology of knowledge, and critical theory to understand economics not as a neutral science but as a social practice with political effects—a way of making worlds, not just describing them.

Example: "Her book showed how economic models don't just describe markets—they create them, training people to behave as the models predict. Critical Theory of Economics: turning critique from the economy to economics itself."
