Ignaz Semmelweis’s discovery of the importance of asepsis is a famous example of a selective encoding insight in science. While on the staff of the general hospital in Vienna, Semmelweis noticed that more women on the poor ward were dying from infection during childbirth than were women on the rich ward. He encoded that doctors, even if they came straight from working on cadavers, seldom washed their hands before they had contact with the poor women, and he realized the relevance that this had for spreading puerperal fever. Unfortunately, Semmelweis was ridiculed for this insight and committed suicide before others accepted the relevance of his discovery. (из The psychology of problem solving)
