The Semmelweis Reflex is a metaphor for the reflex-like tendency to reject new evidence or new knowledge because it contradicts established norms, beliefs or paradigms.
This basically sums up my experience in trying to let people know planet formation is the process of star evolution, the "star" is the new planet, and the "planet" is the ancient star. They are not mutually exclusive!
"In his book The Game of Life, Timothy Leary provided the following polemical definition of the Semmelweis reflex: "Mob behavior found among primates and larval hominids on undeveloped planets, in which a discovery of important scientific fact is punished". The expression has found way into philosophy and religious studies as "unmitigated Humean skepticism concerning causality".
Punish the person who dares threaten the belief systems! Ban him from forums! Call him names and ridicule!!
Can you imagine if people still believed germs couldn't be transmitted via hands? Ebola anybody?
