Semmelweis Reflex

The Semmelweis reflex is a term used to describe the tendency to reject new ideas or evidence that contradicts established beliefs. Named after the Hungarian doctor Ignaz Semmelweis, who discovered that washing hands can prevent infections, it highlights how individuals or institutions may ignore or dismiss important information due to resistance to change. This psychological phenomenon can hinder progress in fields like medicine, science, and social issues, as it often involves clinging to traditional practices despite new evidence that suggests a better approach.
