Critical Thinking Biases

The meta-collection of cognitive biases that specifically distort, undermine, or corrupt the practice of critical thinking itself. These are not ordinary biases that affect any judgment, but biases that attack the very tools we use to think clearly about bias. They include the bias to consider one's own thinking "critical" while dismissing others' as biased, the bias to apply skeptical standards asymmetrically (strictly to views one dislikes, leniently to views one favors), the bias to treat "critical thinking" as a label one claims rather than a practice one performs, and the bias to mistake cynicism for critique. Critical Thinking Biases are what happens when people weaponize the language of reason against reason itself—using "just asking questions" to spread doubt, demanding "evidence" only from opponents, treating one's own unexamined assumptions as "first principles." They are the pathologies of the proudly rational.

Example: "He thought he was immune to bias because he was a 'critical thinker'—but his Critical Thinking Biases meant he applied skepticism only to views he already distrusted, never to his own."

Critical Thinking Bias

The specific cognitive distortion where one mistakes the performance of skepticism for the practice of genuine critical inquiry. Critical Thinking Bias operates when someone believes that merely asking questions, demanding evidence, or pointing out uncertainty constitutes critical thinking—regardless of whether those questions are good faith, whether the evidence demanded is appropriate, or whether the uncertainty is relevant. It's the bias that produces the "just asking questions" pseudo-skeptic, the sea lion who "just wants evidence" for claims they've already decided are false, the debunker who treats their own cultural assumptions as universal standards of reason. Critical Thinking Bias turns the tools of rational inquiry into weapons of dismissal, transforming "critical thinking" from a practice of genuine openness into a performance of intellectual superiority.

Example: "He wasn't critically thinking—he was performing Critical Thinking Bias, 'just asking questions' in bad faith while treating his own assumptions as too obvious to need examination."
