Fallacy of Exhaustive Rationality

The mistaken belief that only perfectly rational beings—free from emotion, bias, and human limitation—can make valid judgments. This fallacy rejects all human reasoning as insufficiently rational, demanding standards that no human can meet. The Fallacy of Exhaustive Rationality is beloved of those who want to dismiss perspectives they dislike—women are too emotional, minorities are too biased, the poor are too desperate—while exempting themselves from similar scrutiny. It's the logic of "you're not being rational, so your view doesn't count," applied selectively to silence opponents while ignoring one's own irrationality. The cure is recognizing that rationality is not a binary state but a spectrum, and that all humans—including the accuser—operate with bias, emotion, and limitation.

Example: "He dismissed her concerns about workplace discrimination as 'emotional, not rational.' The Fallacy of Exhaustive Rationality had been deployed: her experience was invalid because it wasn't delivered with perfect objectivity. Never mind that his own views were shaped by unexamined bias; exhaustive rationality was demanded of her, not him. The double standard was the point."
