Argumentum ad Te

A fallacy distinct from ad hominem—not directly attacking the person, but using their own position or response as supposedly proving the opposing point. "You are proving the point of this post" is the classic form. The move claims that the very fact someone is arguing, or how they're arguing, demonstrates the truth of what they're opposing. It's a meta-fallacy that turns engagement itself into evidence against you. Unlike ad hominem (which attacks character), Argumentum ad Te attacks your relationship to the argument—your response becomes proof that you're wrong. It's a rhetorical trap: if you respond, you prove their point; if you don't, you also prove their point.

"I critiqued a political post. Response: 'Your angry response just proves the post right!' That's Argumentum ad Te—using my engagement as evidence against me. Not addressing my points, just claiming my response proves theirs. It's a conversation-ender dressed as insight. The only winning move is not to play, but they count that as proof too."

Argumentum ad Verbum

A fallacy where the focus shifts to the words used in an argument rather than the argument's content. "You are trivializing the word X" becomes a way of dismissing claims without engaging them. The move criticizes word choice, terminology, or phrasing—often legitimately, but fallaciously when the word critique substitutes for content engagement. Words matter, but when "you're using the wrong term" becomes the whole response, the substance gets lost. Argumentum ad Verbum is particularly common in online debates where semantic nitpicking replaces substantive discussion.

"I described an experience as 'traumatic.' Response: 'You're trivializing real trauma by using that word casually.' That's Argumentum ad Verbum—focusing on my word choice, not my experience. Maybe the word was imperfect; maybe not. Either way, my point about what I experienced remains unaddressed. Words matter, but using them as a shield against engagement is fallacy."

Argumentum ad Te et Verbum

A compound fallacy combining Argumentum ad Te and Argumentum ad Verbum: claiming that someone is proving the opposing point by their word choice. "You are proving the point of the post by trivializing the word X" is the classic form. The move claims that the way someone uses language demonstrates the truth of what they're opposing—a double evasion that avoids content by focusing on the relationship between word choice and argumentative position. It's meta, it's clever, and it's completely unresponsive to substance.

"I used the term 'conspiracy theory' carefully in a critique. Response: 'See? You're using that term exactly how the post said people would—you're proving its point!' That's Argumentum ad Te et Verbum—using my word choice and my position to dismiss my argument without engaging it. My word choice becomes evidence against me, my response becomes proof of their point. It's a rhetorical hall of mirrors with no exit."

Argumentum Ad Probationem

The classic "you are proving my point" fallacy—a form of Argumentum Ad Te where the responder claims that the opponent's response, tone, or very engagement demonstrates the truth of the original position. "You're proving my point by getting angry." "Your response proves exactly what I was saying." The move turns any engagement into evidence against you: if you respond emotionally, you're proving their point about emotionalism; if you respond calmly, you're proving their point about detachment; if you don't respond, you're proving their point about avoidance. It's a rhetorical trap with no exit—any response is reframed as confirmation. The fallacy lies in treating engagement as evidence, rather than addressing what's actually said.

Argumentum Ad Probationem "I calmly explained why I disagreed. Response: 'See? You're proving my point by being so defensive.' That's Argumentum Ad Probationem—using my engagement as evidence, not addressing my arguments. Defensive? I was calm. But even if I were defensive, that doesn't address my points. It's a trap: any response proves them right."

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."

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 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."
