A fallacy where one dismisses an opponent's argument by making the opponent themselves the problem—"the issue is you," "you are the common denominator," "the problem is in you." Unlike ad hominem (which attacks character), Tu Es Fallacy focuses on the person as the source of all problems in the discussion, relationship, or situation. It's a move that shifts blame from the argument's content to the arguer's very existence in the conversation. "You are the common factor in all your failed relationships" (therefore your critique of this relationship is invalid). "You're the problem" (therefore nothing you say matters). The fallacy lies in using personhood as refutation—as if being the "common denominator" proves the argument wrong. It's psychological dismissal dressed as insight, therapy-speak as debate tactic.
"She pointed out patterns of behavior in the group. Response: 'You know, you're the common denominator in all these conflicts. Have you considered that the problem is you?' That's Tu Es Fallacy—dismissing her observations by making her the issue. Maybe she's right; maybe she's wrong. But making her the problem avoids addressing what she said. The argument disappears because the arguer becomes the pathology."

Get the Tu Es Fallacy mug.The theory that fallacies exist on a spectrum, not as a binary category of "fallacious" vs. "valid." The Fallacy Spectrum recognizes that what counts as a fallacy depends on context, purpose, and degree. An argument that's clearly fallacious in a formal debate may be reasonable in everyday conversation; a claim that's somewhat fallacious may still point toward truth; a fallacy that's harmless is different from one that's destructive. The spectrum allows for distinguishing between different kinds and degrees of fallaciousness, for evaluating arguments rather than just labeling them. A hasty generalization from limited data is different from one with no data; an ad hominem that's relevant is different from one that's pure distraction. The Theory of the Fallacy Spectrum calls for mapping where arguments fall on multiple axes of fallaciousness.
Theory of the Fallacy Spectrum Example: "He called every argument he disagreed with 'fallacious.' The Theory of the Fallacy Spectrum showed why that was itself fallacious: fallacies come in degrees. A weak analogy is less fallacious than a complete non sequitur; a relevant ad hominem is less fallacious than a pure attack. The spectrum demanded actual evaluation, not just labeling."

Get the Theory of the Fallacy Spectrum mug.A fallacy and bias where two or more oppressive or repressive systems, institutions, or practices are treated as fundamentally incomparable solely because of their stated or intended purpose, despite producing identical or functionally equivalent harms. The fallacy lies in substituting intent for impact, purpose for consequence. When someone argues that CECOT prison in El Salvador "doesn't compare" to Sednaya prison in Syria because one is for "rehabilitation" (or "fighting gangs") while the other was for political repression, they commit the False Purpose Fallacy—as if the experience of the prisoner, the deprivation of liberty, the violence of the state, and the suffering of the confined were somehow different because the official justification differs. Similarly, when Western AI surveillance is distinguished from authoritarian surveillance because "we're protecting democracy" while "they're controlling dissent," the same fallacy operates: the purpose stated differs, but the surveillance functions similarly. The fallacy is false because purpose does not negate parallel function; good intentions do not transform oppressive machinery into something else; stated goals do not alter lived experience.
Example: "He insisted CECOT wasn't comparable to Sednaya because El Salvador was 'fighting gangs' while Syria was 'crushing dissent'—pure False Purpose Fallacy, as if prisoners experience their cages differently based on the press releases justifying their imprisonment."

Get the False Purpose Fallacy mug.A fallacy and metafallacy where one invokes "objective truth" not as a genuine commitment to inquiry but as a rhetorical weapon to legitimize their own worldview while delegitimizing all others. The fallacy lies in claiming that one's framework simply is objective reality, that one's conclusions are truth itself, and therefore that any alternative is not just wrong but unreal. It's a metafallacy because it preemptively immunizes one's position from critique—if you claim to speak for objective truth itself, then challenging you is challenging reality. The Objective Truth Fallacy transforms the legitimate pursuit of truth into a cudgel for intellectual domination, using the concept of objectivity to shut down inquiry rather than advance it.
Example: "He didn't argue that his view was supported by evidence—he claimed it was objective truth, and that anyone who disagreed was simply denying reality. Classic Objective Truth Fallacy: using the concept of truth to avoid having to demonstrate it."

Get the Objective Truth Fallacy mug.A fallacy and metafallacy where scientific evidence is invoked to justify positions that lie outside the proper domain of evidence—particularly bigotry, prejudice, racism, xenophobia, aporophobia (hatred of the poor), and other forms of discrimination. The fallacy operates by claiming that discriminatory policies or attitudes are "supported by evidence" (about crime rates, economic impacts, cultural differences) while ignoring that evidence never dictates values, that statistical patterns don't justify moral judgments, and that using evidence to justify oppression misuses the very concept of evidence. It's a metafallacy because it weaponizes the legitimate authority of science to defend what science cannot possibly justify—treating "evidence-based" as a blank check for any position that can find a supporting statistic, regardless of the values, ethics, and human consequences involved.
Example: "He cited crime statistics to justify housing discrimination—the Evidence-Based Fallacy in full flower, using numbers to launder prejudice while pretending that evidence alone could ever justify treating humans as less than human."
