Pathological science (nonfiction)

Pathological science is an area of research where "people are tricked into false results ... by subjective effects, wishful thinking or threshold interactions."

The term was first used by Irving Langmuir, Nobel Prize-winning chemist, during a 1953 colloquium at the Knolls Research Laboratory. Langmuir said a pathological science is an area of research that simply will not "go away"—long after it was given up on as "false" by the majority of scientists in the field. He called pathological science "the science of things that aren't so".

Bart Simon lists it among practices pretending to be science: "categories ... such as ... pseudoscience, amateur science, deviant or fraudulent science, bad science, junk science, and popular science ... pathological science, cargo-cult science, and voodoo science".

Examples of pathological science may include Martian canals, N-rays, polywater, and cold fusion. The theories and conclusions behind all of these examples are currently rejected or disregarded by the majority of scientists.

Pathological science, as defined by Langmuir, is a psychological process in which a scientist, originally conforming to the scientific method, unconsciously veers from that method, and begins a pathological process of wishful data interpretation (see the observer-expectancy effect and cognitive bias). Some characteristics of pathological science are:

• The maximum effect that is observed is produced by a causative agent of barely detectable intensity, and the magnitude of the effect is substantially independent of the intensity of the cause.
• The effect is of a magnitude that remains close to the limit of detectability, or many measurements are necessary because of the very low statistical significance of the results.

There are claims of great accuracy.

• Fantastic theories contrary to experience are suggested.
• Criticisms are met by ad hoc excuses.
• The ratio of supporters to critics rises and then falls gradually to oblivion.
