"a severe mental disorder in which thought and emotions are so impaired that contact is lost with external reality".
New Oxford American Dictionary
This page is dedicated to the many people who have occasionally drifted into my office, or sent me e-mail, or even mailed me their books, eager to tell me about their new theory, which they know will turn all known physics on its head, even though they have only studied an infinitesimal fraction of the latter. Some of them are just ignorant or naive, but are willing to learn; this page is not about them.
There is a distinction between "artistic" scientists & true quacks. The former have some bold new hypotheses (i.e., educated guesses) that have not completely confronted reality. (A former advisor of mine had a bumper-sticker-like sign in his office that went something like, "Your new theory is beautiful and elegant. Too bad it's wrong.") The latter have old ideas that have been fudged to try to reproduce some of the results of new ideas. (For example, anyone sticking to Ptolemaic epicycles after the advent of Copernicus & Kepler would fall into this category. Fairy tales are also old ideas.) Real quacks would not even make good science fiction authors.
On the other hand, there are also "pessimistic" scientists. They do not reject proven science, but refuse to consider new conjectures until they have been proven beyond a shadow of a doubt. Unfortunately, playing it safe seldom leads to new discoveries. ("Nothing ventured, nothing gained.") These also differ from quacks, who tend to reject proven science of much (if not all) of the 20th century.
Quacks (also known as "crackpots" or "cranks") have several well-known mental conditions in common with otherconspiracy theorists:

Quacks (also known as "crackpots" or "cranks") have several well-known mental conditions in common with otherconspiracy theorists:
- Paranoia: No one will listen to their self-contradictory claims; therefore there must be a world-wide web of conspiracy, lasting generations (apparently even between opposing sides through the World Wars & Cold War) to promote fantastic theories which, for some unexplained reason, seem sufficient for the design & operation of modern technology.
- Delusion/denial: For some unclear reason (religion? artistic taste? lack of ability or motivation?) they reject well-established science, & replace it with something of their own invention that they find more satisfying.
- Grandiosity: Their theory could never be wrong; therefore everyone else's must be. They want only to talk and not to listen. Their pride blinds them to their incompetence: They are not good con men; their arguments are unoriginal & transparently wrong to any expert.
- Projection: They accuse scientists of all of these obvious failings of their own, before their victims get a chance to respond. After all, it's only 1 person's word against another. (In common terms, this is known as, "He who smelt it, dealt it.") Thus, all established scientists are scientifically incompetent, ignorant, derisive, religious fanatics, mentally ill, etc.. It's a wonder that society has managed to advance @ all.
