Rationalist Violence

A specific subtype of rational violence associated with online rationalist communities (often influenced by LessWrong, effective altruism, or neoreaction). Rationalist violence weaponizes Bayesian reasoning, expected utility calculations, and “epistemic hygiene” to dismiss experiences, emotions, or values that don’t fit the framework. It can manifest as demanding “error corrections” for personal stories, rejecting art as “inefficient signaling,” or labeling spiritual experiences as “cognitive biases.” The violence lies in reducing the richness of human life to a spreadsheet and then attacking anyone who refuses to be reduced.
Example: “When she spoke of her religious conversion, he interrupted with a lecture on ‘confirmation bias’ and ‘Bayesian priors’—rationalist violence, treating a life-changing experience as a statistical error to be debugged.”

Rationalist Violence

Physical, psychological, or structural harm inflicted on individuals or groups because their ways of knowing are deemed “irrational.” Rationalist violence can include forced conversion to secular norms, suppression of religious practices, pathologizing of non‑rational forms of expression, and online harassment of those who rely on intuition or faith. It is often perpetrated by institutions (schools, courts, medical systems) that enforce a narrow rationalist orthodoxy.
Example: “The school expelled a student for citing her cultural traditions in a class discussion, calling it ‘irrational thinking’—rationalist violence, punishing difference in the name of reason.”

Rationalist Alienation

The experience of being disconnected from one’s own emotional, intuitive, or embodied self due to pressure to conform to a hyper‑rationalist worldview. It is the feeling that one’s own feelings are “illogical,” one’s intuitions are “biases,” and one’s body is just a machine. Rationalist alienation is common in communities that prize pure reason and dismiss emotional intelligence, leading to burnout, depression, and a sense of living as a disembodied brain.

Example: “He had learned to analyze his feelings away, but underneath was a hollow ache—rationalist alienation, the cost of treating oneself as a logic engine.”

fache-couture 

French slang, which translated, means "bull's fashion" but basically equates to "hyper trendy" or overly trendy. Used when a person wishes to express distaste at the latest fashion trend/fad, because it seems that everyone has a certain item of clothing or is wearing it.
