Appeal to Evidence

A fallacy where someone demands "evidence" in a way that assumes only certain kinds of evidence count, or where "evidence" is invoked as a magic word that ends discussion without specifying what evidence, from where, or why it's convincing. Often used to dismiss personal experience, testimonial knowledge, or qualitative research: "That's just anecdotal—where's the real evidence?" The fallacy lies in treating "evidence" as a unitary thing rather than a spectrum, and in using the demand for evidence as a way to dismiss rather than inquire.

"I shared my experience of discrimination. Response: 'Do you have evidence for that?' They meant: do you have video, documentation, witnesses? My experience wasn't evidence to them. That's Appeal to Evidence—using the word to dismiss what you've already decided doesn't count. Evidence is real; using it as a weapon is not."

Appeal to Scientific Method

A fallacy where someone invokes "the scientific method" as a unified, definitive procedure that settles all questions, ignoring that there is no single scientific method, that methods vary by discipline, and that many important questions lie outside science's domain. The appeal is fallacious when used to dismiss non-scientific ways of knowing—philosophy, art, experience, tradition—as if the scientific method were the only path to truth. It's scientism in rhetorical form: using the prestige of scientific procedure to police the boundaries of legitimate inquiry.

Appeal to Scientific Method "You can't know anything about consciousness without fMRI data! That's Appeal to Scientific Method—assuming one method (quantitative neuroscience) is the only method. But phenomenology studies consciousness through experience. Philosophy studies it through reasoning. The scientific method is one tool, not the whole toolbox."

Appeal to Science

A fallacy where someone invokes "science" as an authority to settle a question without specifying which science, what evidence, or how it applies. "Science says..." becomes a magic incantation that ends debate. The appeal is fallacious when it treats science as a monolithic oracle rather than a diverse, contested, evolving set of practices and findings. Science doesn't "say" anything—scientists publish studies, which are interpreted, debated, and sometimes overturned. Appeal to Science is the intellectual's version of "because I said so"—using the prestige of science to avoid the work of argument.

Appeal to Science "I questioned a popular health claim. Response: 'Science says it's true!' Which science? Which studies? Published where? Replicated when? 'Science says' is not an argument—it's a conversation-stopper dressed in a lab coat. Appeal to Science: when you want the authority of science without the responsibility of citing it."

Appeal to Falsifiability

A fallacy where someone argues that because a claim cannot be proven false, it must therefore be false. This inverts the proper use of falsifiability, which is a criterion for scientific status, not a test for falsehood. The fallacy typically appears in debates about religion, spirituality, or metaphysics: "You can't prove God doesn't exist, so God must not exist." But the same logic would prove anything unfalsifiable false—a absurd consequence. The fallacy confuses burden of proof (claims need evidence) with falsifiability as a truth test. Unfalsifiable claims aren't automatically false—they're just not empirically testable. Their truth or falsehood must be evaluated by other standards.

Appeal to Falsifiability - "You can't prove it's false, ergo it must be false" "I mentioned my belief in consciousness beyond the brain. Response: 'You can't prove it's false, so it must be false.' That's Appeal to Falsifiability—demanding disproof as proof of falsehood. By that logic, you can't prove invisible unicorns don't exist, so they must exist. The fallacy works both ways, which is why it's a fallacy."

Unfalsifiability Does Not Equal False

A critical epistemological reminder that the inability to test or potentially disprove a claim does not automatically make that claim false. Unfalsifiability means the claim is structured in a way that resists empirical testing—it doesn't mean the claim is incorrect, meaningless, or worthless. Many important domains involve unfalsifiable claims: metaphysical beliefs, aesthetic judgments, ethical principles, mathematical axioms, and personal experiences. The statement "unfalsifiable claims are false" is itself unfalsifiable—a performative contradiction. The reminder is crucial in debates where skeptics demand falsifiability as the only criterion for truth, ignoring that falsifiability is a criterion for scientific claims, not for all claims. Unfalsifiable doesn't mean false—it means different standards apply.

"You say your spiritual experience is real. Skeptic demands: 'Prove it's false!' That's missing the point. Unfalsifiability Does Not Equal False—it means your claim isn't the kind that gets settled by experiments. Demanding falsifiability from a mystical experience is like demanding a fish to climb a tree. The claim might be true, might be false—but unfalsifiability alone doesn't decide."

Argumenterism

A portmanteau of Argumentum Ad Argumentum and Bulverism, this rhetorical fallacy combines circular reasoning, the genetic fallacy, and argument-labeling with presumption and condescension. The Argumenterist presumes that a speaker's argument is false or invalid without engaging its content, then explains why the argument is being made by attacking its perceived category, motives, or origins—even if the argument might actually be correct. Classic moves: "This is just relativism," "That's postmodernism," "This is pseudoscience," "This is bullshit," "That's an ad hominem fallacy" (while committing one), "This is hasty generalization" (without showing the haste). The fallacy is circular because the presumption of falsity justifies the dismissal, and the dismissal confirms the presumption. It's genetic because it traces the argument to supposedly disreputable origins (relativism, postmodernism, etc.). And it's condescending because the Argumenterist speaks from above, diagnosing the argument's pathologies rather than engaging its substance. Argumenterism is the intellectual's version of sticking fingers in ears—it sounds sophisticated because you're using philosophical vocabulary, but you're still not listening.

"I presented a nuanced critique of institutional power drawing on multiple traditions. Argumenterist response: 'This is just postmodern relativism dressed up as scholarship. You're making these arguments because you've absorbed French theory without understanding its contradictions.' They didn't address a single point—just labeled the argument, diagnosed its origins, and dismissed it from on high. That's Argumenterism: the smug assurance that naming something is the same as refuting it."

Poisoning the Argument

A specific form of Argumentum Ad Argumentum where adverse information about an argument is presented preemptively, before the argument itself is even made, with the intention of discrediting or ridiculing it in advance. The audience is primed to reject whatever follows based on its perceived category or affiliation. Classic example: "This is just relativism" or "This is postmodernism" said before someone presents a view that might be labeled as such. The poison works before the argument has a chance to speak. The audience is now inoculated: anything that sounds remotely like relativism is already dismissed, regardless of its actual content or merit. Poisoning the Argument is rhetorical preemptive strike—killing the argument before it's born, not by addressing its claims but by tainting its category.

Poisoning the Argument "Before I could even explain my perspective on knowledge, they said: 'Let me guess, this is going to be some postmodern relativist nonsense, isn't it?' That's Poisoning the Argument—they poisoned the well before I could drink. Now everything I say is heard through that filter. The argument never had a chance because the category was already condemned."
