Rationality Bias

The cognitive bias where one attempts to apply rational, logical analysis to domains that are fundamentally irrational or non-rational—such as politics, emotion, or faith. Rationality Bias assumes that everything can be reasoned about, that every domain yields to logic, that irrational phenomena have rational explanations that will eventually be found. It leads to endless frustration: trying to logic someone out of a political position they didn't logic themselves into; trying to reason with emotion; trying to prove faith wrong. Rationality Bias mistakes the map for the territory, the tool for the task. It's the bias of those who think reason is the only game in town.

Rationality Bias Example: "He spent years trying to reason his relatives out of their political views—studies, arguments, evidence, logic. Nothing worked. Rationality Bias had convinced him that reason could reach any domain; it couldn't. Politics wasn't about evidence; it was about identity, emotion, belonging. He wasn't arguing; he was banging his head against a wall that reason couldn't penetrate."

Neutral and Impartial Rationality Bias

A bias that treats Western conceptions of rationality—instrumental reason, means-end calculation, cost-benefit analysis—as neutral, universal, and beyond critique. The Neutral and Impartial Rationality Bias ignores that rationality has been defined differently across cultures and historical periods, that the Enlightenment's rationality was shaped by particular social conditions, and that Western rationality has been used to justify colonialism, exploitation, and domination. It presents "rationality" as a pure standard, erasing its history and politics. Those with this bias don't see their rationality as one tradition; they see it as rationality itself. Everyone else is emotional, irrational, or pre-modern.

"Be rational," he said, meaning "calculate costs and benefits like a Western economist." Neutral and Impartial Rationality Bias: treating one form of reasoning as Reason itself. He didn't see that other rationalities exist—relational rationality, ecological rationality, spiritual rationality. His rationality was just rationality; everyone else needed to catch up."
