Lazy Proof Bias
A bias where one refuses to do any investigative work themselves but demands that others provide exhaustive proof, often moving goalposts to avoid ever being satisfied. Lazy proof bias is the cognitive engine of “do your own research” in reverse: the biased party outsources all intellectual labor to the opponent, then uses any gap in the opponent’s evidence as proof of weakness. It is a common tactic in bad‑faith online debates, where one side demands “sources” for every point while offering none themselves.
Example: “He asked for sources, she provided five. He asked for better sources, she provided three peer‑reviewed studies. He then asked for a meta‑analysis. Lazy proof bias: demanding endless work while doing none.”

Intolerant Proof Bias
A rigid, dogmatic form of proof bias that refuses to consider any form of evidence outside a narrow, predetermined range—often quantitative, experimental, or institutionally sanctioned—and treats any appeal to other forms of knowledge as an attack on rationality itself. Intolerant proof bias is characterized by an aggressive, often hostile posture toward qualitative research, experiential knowledge, and non‑Western epistemologies. It does not merely prefer certain evidence; it demands conformity and punishes deviation.
Example: “When she cited oral histories in her anthropology paper, the reviewer wrote ‘this is not evidence.’ Intolerant proof bias: treating any knowledge outside one’s own tradition as inadmissible.”

Discriminatory Proof Bias
The institutional and interpersonal application of proof bias to exclude, disadvantage, or harm individuals or groups. Discriminatory proof bias occurs when organizations require forms of evidence that are structurally harder for some groups to produce—e.g., requiring written documentation from cultures with oral traditions, demanding clinical studies for traditional medicine while accepting corporate white papers for pharmaceuticals, or using “lack of proof” to deny accommodations. It turns evidentiary standards into instruments of discrimination.
Example: “The school refused her request for a quiet space for meditation, citing ‘insufficient evidence of need’—discriminatory proof bias, using evidence requirements to deny accommodations that would have been routine if requested by a dominant group.”

Bigoted Proof Bias
A form of proof bias directed specifically at marginalized groups, beliefs, or practices, where the demand for proof serves to delegitimize entire worldviews or identities. Bigoted proof bias often targets indigenous knowledge, spiritual practices, or cultural traditions, insisting they meet evidentiary standards derived from dominant, Western, materialist frameworks—while ignoring that those frameworks were never applied to the traditions of the powerful. It uses “proof” as a cudgel to enforce epistemic hierarchy and cultural supremacy.
Example: “He demanded ‘proof’ that indigenous land stewardship was effective, while never questioning the ‘proof’ behind industrial agriculture’s claims. Bigoted proof bias: imposing one culture’s evidence rules to erase another’s.”

Selective Proof Bias
A bias where one applies rigorous proof standards only to claims they disagree with, while accepting weak or no evidence for claims they favor. Selective proof bias is the hallmark of motivated reasoning: the same person who demands double‑blind studies for acupuncture will accept anecdotal testimonials for their preferred supplement; who insists on “proof of harm” for environmental regulations will accept speculation about economic benefits. The bias lies not in the standards themselves but in their inconsistent application.
Example: “He rejected climate models as ‘unproven’ but accepted a single op‑ed as proof that deregulation boosts growth. Selective proof bias: rigor for opponents, credulity for allies.”

Impossible Proof Bias
A form of proof bias where one demands evidence that is, in principle, impossible to provide—such as proof of a negative, absolute certainty, or evidence that would require violating the very phenomenon being studied. The goal is not to be convinced but to create an unattainable standard that ensures the opponent always fails. Impossible proof bias often appears in debates about historical events, subjective experience, or metaphysical claims: “prove you weren’t there,” “prove you’re not dreaming,” “prove God doesn’t exist.” It weaponizes the limits of human knowledge to dismiss any position the biased party wishes to reject.
Example: “He demanded she prove that her childhood trauma actually happened—as if memory worked like a video recording. Impossible proof bias: using unrealistic standards to invalidate lived experience.”

Hasty Proof Bias
A bias where one demands immediate, definitive proof at the very start of an inquiry or discussion, treating the inability to produce instant evidence as proof that the claim is false. Hasty proof bias conflates “not yet proven” with “disproven” and ignores the time, resources, and iterative process required to gather evidence. It is often used to shut down exploration of novel ideas, emerging research, or complex topics that cannot be summarized in a soundbite. In debates, it appears as “if you can’t prove it right now, it’s not true.”
Example: “He asked her about a recent preprint and demanded proof on the spot. When she said the study was still being replicated, he declared ‘so it’s false.’ Hasty proof bias: treating provisional knowledge as debunked.”
