A more intense form of scientific fanaticism, rooted in scientism—the belief that science is the only legitimate source of knowledge. Scientistic fanatics treat every human question (meaning, morality, art, love) as ultimately a scientific problem, and dismiss any non‑scientific approach as worthless or irrational. They exhibit purity spirals, attacking even other scientists who acknowledge the limits of science. Their zealotry often extends to praising “the scientific worldview” as a total replacement for philosophy, religion, or humanities, and they react with fury to suggestions that science might have boundaries.
