Prejudice and discrimination that elevates a particular conception of rationality—often formal
logic, empirical evidence, and dispassionate analysis—as the sole legitimate mode of thought, while dismissing emotional, intuitive, or relational ways of knowing as inferior or pathological. Rationalist bigotry attacks not just ideas but the people who hold them, accusing them of irrationality, emotional weakness, or mental deficiency. It often overlaps with atheist bigotry and scientific ableism, using the
language of reason to justify exclusion and humiliation.
Example: “He told her that her ethical intuition was ‘just emotion’ and that only utilitarian calculation was rational—rationalist bigotry, using one model of reason to delegitimize another.”
Rationalist Prejudice
The cognitive bias that automatically privileges formal
logic and empirical evidence over all other forms of reasoning, while dismissing intuition, tradition, or lived experience as inherently unreliable. It operates as a default assumption: “if it’s not rational (by my
definition), it’s not worth considering.” Rationalist prejudice leads to the systematic exclusion of
feminist epistemology, indigenous knowledge, and even common‑sense practical reasoning from academic and public discourse.
Example: “She proposed a community‑
based solution based on local experience; he dismissed it as ‘anecdotal’ and demanded an RCT—rationalist prejudice, refusing to recognize other
valid forms of evidence.”
