Here's something to make you go ooooommmm.
The Semmelweis reflex or “Semmelweis effect” is a metaphor for the reflex-like tendency to reject new evidence or new knowledge because it contradicts established norms, beliefs or paradigms.
Ignaz Philipp Semmelweis (1 July 1818 – 13 August 1865) was a Hungarian physician of ethnic-German ancestry, now known as an early pioneer of antiseptic procedures. Described as the “saviour of mothers”, Semmelweis discovered that the incidence of puerperal fever (also known as “childbed fever”) could be drastically cut by the use of hand disinfection in obstetrical clinics. Puerperal fever was common in mid-19th-century hospitals and often fatal. Semmelweis proposed the practice of washing hands with chlorinated lime solutions in 1847 while working in Vienna General Hospital’s First Obstetrical Clinic, where doctors’ wards had three times the mortality of midwives’ wards. He published a book of his findings in Etiology, Concept and Prophylaxis of Childbed Fever.
Despite various publications of results where hand washing reduced mortality to below 1%, Semmelweis’s observations conflicted with the established scientific and medical opinions of the time and his ideas were rejected by the medical community. Semmelweis could offer no acceptable scientific explanation for his findings, and some doctors were offended at the suggestion that they should wash their hands. Semmelweis’s practice earned widespread acceptance only years after his death, when Louis Pasteur confirmed the germ theory and Joseph Lister, acting on the French microbiologist’s research, practiced and operated, using hygienic methods, with great success.
