Semmelweis Reflex

The Semmelweis Reflex refers to the natural human tendency to reject or dismiss new or innovative ideas or information without proper examination or consideration. This reflex often occurs when the new ideas challenge long-held beliefs, established practices, or existing ideologies.

Semmelweis Effect

The Semmelweis Effect is a specific manifestation of the Semmelweis Reflex in which the rejection or suppression of new knowledge or ideas is not only immediate but also long-lasting. It involves the systemic dismissal or refusal to accept new information despite strong evidence supporting its validity.

The term “Semmelweis Reflex” is named after Ignaz Semmelweis, a Hungarian physician who discovered the importance of hand hygiene in preventing the spread of infections during childbirth. However, his groundbreaking findings were initially met with resistance and skepticism by the medical community, leading to the unfortunate consequences of delayed progress and preventable deaths.
