What does the Semmelweis reflex refer to?

The Semmelweis reflex refers to the phenomenon where new evidence or information is dismissed or rejected, particularly if it challenges established beliefs or practices, similar to how Ignaz Semmelweis's findings about the benefits of handwashing in hospitals were initially ignored and ridiculed by the medical establishment in the 19th century. This concept highlights a common cognitive bias where individuals may resist change or reject new ideas because they conflict with pre-existing notions or authority figures.

Understanding this reflex is important because it showcases the need for openness to new ideas and evidence, especially in fields such as healthcare and nutrition, where outdated beliefs may persist despite new research. This recognition underscores the significance of being adaptive and willing to evaluate practices based on emerging evidence rather than sticking to tradition. The other options presented do not align with the essence of the Semmelweis reflex; instead, they touch on different psychological or sociological phenomena.
