Objective Truth Bias

The specific bias where one believes their own perspective, framework, or worldview simply is objective truth—not a perspective among perspectives, but reality itself perceived clearly. Objective Truth Bias operates when someone says "I'm not biased, I just see things as they really are" while everyone else is blinded by ideology, culture, or self-interest. It's the bias that makes one's own assumptions invisible—they're not assumptions, they're just true. This bias is the cognitive foundation of dogmatism: if you believe you have direct access to objective reality, then disagreement can only be explained by error, bad faith, or pathology in others.

Example: "He didn't argue his position—he simply asserted it as objective truth, and treated all disagreement as evidence of his opponents' irrationality. That's not confidence; that's Objective Truth Bias."

Evidence-Based Bias

The specific bias where one treats "evidence-based" as an automatic warrant for one's position and a automatic disqualifier for others', without actually engaging the quality, relevance, or interpretation of the evidence. Evidence-Based Bias operates when someone says "the evidence supports my view" as a conversation-ender, without acknowledging that evidence is always interpreted, that different evidence can support different conclusions, that evidence alone never dictates policy or values, and that "evidence-based" is often claimed by all sides. It's the bias that turns the legitimate principle of grounding claims in evidence into a rhetorical cudgel.

Example: "He kept saying his position was 'evidence-based' as if that settled everything—pure Evidence-Based Bias, using the word 'evidence' to avoid actually discussing what the evidence showed."

Purpose Bias

A cognitive bias where you perceive two or more things that are functionally identical, structurally similar, or practically equivalent as fundamentally different solely because their intended purposes differ. It's the mental shortcut that makes a luxury handbag feel like a "wise investment" while an identical unbranded bag is "frivolous spending." The same knife in a kitchen is a "tool" but in a pocket is a "weapon." A loud car exhaust is "performance" on a sports car but "noise pollution" on a beat-up sedan. Purpose Bias shapes how we judge, categorize, and value objects, actions, and even people based on what we believe they're for, rather than what they actually are. In daily life, it's why we excuse our own harsh words as "honest feedback" while condemning others' identical words as "verbal abuse"—same statement, different purpose, completely different judgment. The bias lies in treating purpose as a magical property that transforms the very nature of things, rather than as one attribute among many.

Example: "He called his own constant phone checking 'staying connected' but his partner's identical behavior 'addiction'—pure Purpose Bias, seeing the same action as completely different based solely on whose purpose he assumed."

Normalization Bias

A cognitive bias and metabias, common in scientific and expert communities, where the tools of science, evidence, and inquiry are deployed to normalize the status quo and/or the current political, economic, and social system. Normalization Bias operates when researchers unconsciously (or consciously) frame their questions, interpret their data, and present their findings in ways that make existing power structures seem natural, inevitable, or optimal. Poverty becomes a matter of "individual choices" rather than systemic extraction; inequality becomes "natural variation" rather than policy outcome; exploitation becomes "market efficiency" rather than violence. The bias lies in using the authority of science to launder the contingent into the necessary, turning "what is" into "what must be" through the alchemy of normalized framing. It's a metabias because it shapes not just individual findings but entire fields' approaches to what questions are worth asking.

Example: "The study 'proved' that poverty was caused by poor decision-making—completely ignoring that the decisions available to poor people were structurally constrained. Normalization Bias: using science to make oppression look like choice."

Ivory Bias

The specific cognitive distortion where one privileges academic, intellectual, or expert perspectives over all others, not because they've been tested and found superior, but simply because they originate from within the ivory tower. Ivory Bias operates when a professor's opinion is treated as more valuable than a practitioner's experience, when peer-reviewed publication is treated as the only legitimate form of knowledge, when credentialled expertise automatically outweighs lived experience, when "studying" something is considered superior to actually doing it. The bias lies in mistaking institutional position for epistemic privilege—assuming that being inside the ivory tower means seeing more clearly, when it might just mean seeing differently, or seeing less of what matters.

Example: "He dismissed her decades of community organizing as 'anecdotal' while citing a grad student's survey as 'evidence'—pure Ivory Bias, treating proximity to the academy as proximity to truth."
