Placebist Bias

A cognitive bias where one automatically attributes any positive outcome from alternative, complementary, or unconventional treatments to the placebo effect, without considering other mechanisms or evidence. Placebist Bias is the default assumption that if it's not conventional medicine, it must be placebo—regardless of research, mechanism, or patient experience. The bias protects materialist orthodoxy by explaining away anomalies rather than investigating them. It's the mirror image of credulity: instead of believing everything, it disbelieves everything that doesn't fit the framework.

"She tried acupuncture for chronic pain and got relief. Placebist Bias says: placebo, obviously. Never mind the studies showing physiological effects; never mind the patient's experience. The bias assumes placebo because the alternative is uncomfortable. Placebist Bias isn't skepticism; it's dogma in disguise. It explains away rather than explains."

Denial Bias

A cognitive bias where one systematically denies, rejects, or dismisses information that contradicts existing beliefs, regardless of evidence. While confirmation bias seeks confirming information, Denial Bias actively refuses contradictory information—not just ignoring it, but fighting it, explaining it away, or attacking its source. It's the bias of the closed mind, the immune system of belief rejecting foreign evidence. Denial Bias explains why facts don't change minds: the mind isn't processing facts; it's denying them.

"He didn't just ignore the evidence; he attacked it, questioned its sources, invented conspiracies to explain it away. That's Denial Bias—not just failing to seek confirming information, but actively rejecting anything that threatens what he already believes. Facts don't work on denial; denial works on facts."

Contestation Bias

A bias where one automatically contests, challenges, or disputes any information that doesn't align with preexisting views. Contestation Bias doesn't just ignore opposing evidence; it actively fights it, demanding impossible standards, shifting goalposts, and finding reasons to reject. It's the bias of perpetual opposition—the mind that says "no" before hearing the question.

"Every study she cited, he contested. Methodology, sample size, funding source—always a reason to reject. Contestation Bias isn't skepticism; it's automatic opposition. Not "show me evidence," but "your evidence is never enough." The contest is the point; truth is secondary."

Objection Bias

A reflexive tendency to object to any claim that conflicts with one's existing beliefs. Objection Bias operates at the level of instinct: before evaluation, before consideration, the mind says "no." It's the cognitive equivalent of a knee-jerk reaction—objection first, reasoning later (if ever). The bias protects existing beliefs by making objection the default response to challenge.

"She hadn't even finished her sentence before he objected. Didn't matter what she said; if it challenged him, the answer was no. Objection Bias: the mind that says no before it knows what it's saying no to. Not reasoning, just reflex."

Invalidation Bias

A bias where one systematically invalidates sources of opposing information—attacking credibility, questioning motives, dismissing expertise—rather than engaging the information itself. Invalidation Bias doesn't need to refute claims; it just needs to discredit the source. If the source can't be trusted, the information doesn't need to be considered.

"He never addressed her arguments—just attacked her credentials, her funding, her personal life. Invalidation Bias: when you can't beat the message, discredit the messenger. The information remains unaddressed, but that's the point. Invalidate first, think never."

Discrediting Bias

A bias focused on systematically undermining the credibility of people, sources, or institutions that provide opposing information. Discrediting Bias goes beyond questioning evidence to questioning the very possibility that certain sources could be trustworthy. It's the bias of poisoning the well before any water is drawn—making it impossible for opposing information to be heard because its sources have been pre-emptively discredited.

"Before she even presented her findings, he'd already discredited her field, her university, her entire discipline. Discrediting Bias: making sure no evidence from certain sources can ever count. Not engaging the argument, but ensuring the argument can never be heard."

Demystification Bias

A bias where one systematically demystifies, debunks, or explains away any information that doesn't fit existing frameworks—often under the guise of skepticism or rationality. Demystification Bias presents itself as critical thinking but functions as a defense mechanism: anything unfamiliar, challenging, or anomalous must be reduced to familiar categories, explained away, or revealed as illusion. It's the bias of the person who always has an explanation for why you're wrong.

"Every spiritual experience, every anomalous phenomenon, every challenge to his worldview—he had a debunking ready. Demystification Bias: skepticism as armor, explanation as defense. Not openness to mystery, but the compulsion to eliminate it. The world must fit his framework; anything else gets explained away."
