Semmelweis Reflex
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. The term derives from the name of Ignaz Semmelweis, a Hungarian physician who discovered in 1847 that childbed fever mortality rates fell ten-fold when doctors disinfected their hands with a chlorine solution before moving from one patient to another, or, most particularly, after an autopsy. (At one of the two maternity wards at the university hospital where Semmelweis worked, physicians performed autopsies on every deceased patient.) Semmelweis's procedure saved many lives by stopping the ongoing contamination of patients (mostly pregnant women) with what he termed "cadaverous particles", twenty years before germ theory was discovered. Despite the overwhelming empirical evidence, his fellow doctors rejected his hand-washing suggestions, often for non-medical reasons. For instance, some doct ...

Reflex
In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action and nearly instantaneous response to a stimulus. Reflexes are found with varying levels of complexity in organisms with a nervous system. A reflex occurs via neural pathways in the nervous system called reflex arcs. A stimulus initiates a neural signal, which is carried to a synapse. The signal is then transferred across the synapse to a motor neuron which evokes a target response. These neural signals do not always travel to the brain, so many reflexes are an automatic response to a stimulus that does not receive or need conscious thought. Many reflexes are fine-tuned to increase organism survival and self-defense. This is observed in reflexes such as the startle reflex, which provides an automatic response to an unexpected stimuli, and the feline righting reflex, which reorients a cat's body when falling to ensure safe landing. The simplest type of reflex, a short-latency reflex, has a s ...

Thomas Szasz
Thomas Stephen Szasz ( ; hu, Szász Tamás István ; 15 April 1920 – 8 September 2012) was a Hungarian-American academic and psychiatrist. He served for most of his career as professor of psychiatry at the State University of New York Upstate Medical University in Syracuse, New York. A distinguished lifetime fellow of the American Psychiatric Association and a life member of the American Psychoanalytic Association, he was best known as a social critic of the moral and scientific foundations of psychiatry, as what he saw as the social control aims of medicine in modern society, as well as scientism. His books ''The Myth of Mental Illness'' (1961) and ''The Manufacture of Madness'' (1970) set out some of the arguments most associated with him. Szasz argued throughout his career that mental illness is a metaphor for human problems in living, and that mental illnesses are not "illnesses" in the sense that physical illnesses are, and that except for a few identifiable brain diseases ...
