Crank is a pejorative term used for a person who holds an unshakable belief that most of their contemporaries consider to be false. Common synonyms for crank include crackpot and kook. A crank belief is so wildly at variance with those commonly held that it is considered ludicrous. Cranks characteristically dismiss all evidence or arguments which contradict their own unconventional beliefs, making any rational debate a futile task and rendering them impervious to facts, evidence, and rational inference.

A crank differs from a fanatic in that the subject of the fanatic's obsession is either not necessarily widely regarded as wrong or not necessarily a "fringe" belief. Similarly, the word quack is reserved for someone who promotes a medical remedy or practice that is widely considered to be ineffective; this term, however, does not imply any deep belief in the idea or product they are attempting to sell.

Although experts in the field find a crank's beliefs ridiculous, cranks are sometimes very successful in convincing non-experts of their views. A famous example is the Indiana Pi Bill, by which a state legislature nearly wrote into law a crank result in geometry.

Common characteristics
The second book of the mathematician and popular author Martin Gardner was a study of crank beliefs, Fads and Fallacies in the Name of Science. More recently, the mathematician Underwood Dudley has written a series of books on mathematical cranks, including The Trisectors, Mathematical Cranks, and Numerology: Or, What Pythagoras Wrought. And in a 1992 UseNet post, the mathematician John Baez humorously proposed a checklist, the Crackpot index, intended to diagnose cranky beliefs regarding contemporary physics.

According to these authors, virtually universal characteristics of cranks include:
 * 1) Cranks overestimate their own knowledge and ability, and underestimate that of acknowledged experts.
 * 2) Cranks insist that their alleged discoveries are urgently important.
 * 3) Cranks rarely, if ever, acknowledge any error, no matter how trivial.
 * 4) Cranks love to talk about their own beliefs, often in inappropriate social situations, but they tend to be bad listeners, being uninterested in anyone else's experience or opinions.

Some cranks lack academic achievement, in which case they typically assert that academic training in the subject of their crank belief is not only unnecessary for discovering the truth, but actively harmful because they believe it poisons the minds by teaching falsehoods. Others greatly exaggerate their personal achievements, and may insist that some achievement (real or alleged) in some entirely unrelated area of human endeavor implies that their cranky opinion should be taken seriously.

Some cranks claim vast knowledge of any relevant literature, while others claim that familiarity with previous work is entirely unnecessary.

In addition, the overwhelming majority of cranks:
 * 1) seriously misunderstand the mainstream opinion to which they believe that they are objecting,
 * 2) stress that they have been working out their ideas for many decades, and claim that this fact alone shows that their belief cannot be dismissed as resting upon some simple error,
 * 3) compare themselves with luminaries in their chosen field (often Galileo Galilei, Nicolaus Copernicus, Leonhard Euler, Isaac Newton, Albert Einstein or Georg Cantor), implying that the mere unpopularity of some belief is not good reason for it to be dismissed,
 * 4) claim that their ideas are being suppressed, typically backed up by conspiracy theories invoking intelligence organizations, mainstream science, powerful business interests, or other groups which, they allege, are terrified by the possibility of their revolutionary insights becoming widely known,
 * 5) appear to regard themselves as persons of unique historical importance.

Cranks who contradict some mainstream opinion in some highly technical field, (e.g. mathematics, cryptography, physics) may: That is, cranks tend to ignore any previous insights which have been proven by experience to facilitate discussion and analysis of the topic of their cranky claims; indeed, they often assert that these innovations obscure rather than clarify the situation.
 * 1) exhibit a marked lack of technical ability,
 * 2) misunderstand or not use standard notation and terminology,
 * 3) ignore fine distinctions which are essential to correctly understand mainstream belief.

In addition, cranky scientific theories often do not in fact qualify as theories as this term is commonly understood within science. For example, crank theories in physics typically fail to result in testable predictions, which makes them unfalsifiable and hence unscientific. Or, cranks may present their ideas in such a confused, not even wrong manner that it is impossible to determine what they are actually claiming.

Internet cranks
The rise of the Internet has given another outlet to people well outside the mainstream who may get labeled cranks due to internet postings or websites promoting particular beliefs. There are a number of websites devoted to listing people as cranks. Community-edited websites like Wikipedia have been described as vulnerable to cranks.

Science fiction author and critic Bruce Sterling noted in his essay in CATSCAN 13: "Online communication can wonderfully liberate the tender soul of some well-meaning personage who, for whatever reason, is physically uncharismatic. Unfortunately, online communication also fertilizes the eccentricities of hopeless cranks, who at last find themselves in firm possession of a wondrous soapbox that the Trilateral Commission and the Men In Black had previously denied them."

There are also newsgroups which are nominally devoted to discussing (alt.usenet.kooks) or poking fun at (alt.slack, alt.religion.kibology) supposed cranks.

Crank magnetism
The term crank magnetism was coined by physiologist and blogger Mark Hoofnagle on the Denialism Blog in 2007 to refer to the tendency for cranks to be attracted to claims made by other cranks. Crank magnetism may be considered to operate wherever a single person propounds a number of unrelated denialist conjectures, poorly supported conspiracy theories, or pseudoscientific claims. Thus, some of the common crank characteristics—such as the lack of technical ability, ignorance of scientific terminology, and claims that alternative ideas are being suppressed by the mainstream—may be operating on and manifested in multiple orthogonal assertions.

Hoofnagle's fellow blogger David Gorski has discussed crank magnetism in relation to the writings of British columnist Melanie Phillips, who he alleges denies anthropogenic global warming while promoting intelligent design and the discredited view that the MMR vaccine causes autism in children. Blogger Luke Scientiæ has commented on the relationship between the number of unrelated claims that magnetic cranks make and the extent of their open hostility to science. He has also coined the phrase "magnetic hoax" in relation to hoax claims that attract multiple crank interpretations.

Studies
One study, NASA faked the moon landing—Therefore (Climate) Science is a Hoax: An Anatomy of the Motivated Rejection of Science, gave evidence that climate change denial correlated with moon landing and 9/11 conspiracy theories, staunch beliefs in laissez-faire free-market capitalism, denial of the link between tobacco smoking and lung cancer, HIV/AIDS denialism and MLK death conspiracy theories:

"Although nearly all domain experts agree that human emissions are altering the world's climate, segments of the public remain unconvinced by the scientific evidence. Internet blogs have become a vocal platform for climate denial, and bloggers have taken a prominent and influential role in questioning climate science. We report a survey (N > 1100) of climate blog users to identify the variables underlying acceptance and rejection of climate science. Paralleling previous work, we find that endorsement of a laissez-faire conception of free-market economics predicts rejection of climate science (r ' .80 between latent constructs). Endorsement of the free market also predicted the rejection of other established scientific findings, such as the facts that HIV causes AIDS and that smoking causes lung cancer. We additionally show that endorsement of a cluster of conspiracy theories (e.g., that the CIA killed Martin-Luther King or that NASA faked the moon landing) predicts rejection of climate science as well as the rejection of other scientific findings, above and beyond endorsement of laissez-faire free markets. This provides empirical confirmation of previous suggestions that conspiracist ideation contributes to the rejection of science. Acceptance of science, by contrast, was strongly associated with the perception of a consensus among scientists."

Another study titled Dead and Alive: Beliefs in Contradictory Conspiracy Theories managed to show that not only will cranks be attracted to and believe in numerous conspiracy theories all at once, but will continue to do so even if the theories in question are completely and utterly incompatible with one another. For instance, the study showed that: "... the more participants believed that Princess Diana faked her own death, the more they believed that she was murdered [and that] ... the more participants believed that Osama Bin Laden was already dead when U.S. special forces raided his compound in Pakistan, the more they believed he is still alive," and that "Hierarchical regression models showed that mutually incompatible conspiracy theories are positively associated because both are associated with the view that the authorities are engaged in a cover-up".

Studies such as Belief in Conspiracy Theories state that conspiracy theories relating to the assassination of JFK, the moon landing and the September 11th attacks are united by a common thread: distrust of the government-endorsed story. This leads the believer to attach other conspiracies as well. Someone with a distrust of the government will likely reject any stories or reports directly issued by state agencies or other authorities that are seen as part of the establishment. Thus, any conspiracy will seem more plausible to the conspiracy theorist because this fits with their worldview.

Cultic milieu
In academic sociology, a similar notion to crank magnetism exists, namely Colin Campbell's concept of the cultic milieu, which he used: "...to refer to a society's deviant belief systems and practices and their associated collectivities, institutions, individuals, and media of communication. He described it as including 'the worlds of the occult and the magical, of spiritualism and psychic phenomena, of mysticism and new thought, of alien intelligences and lost civilizations, of faith healing and nature cure' (Campbell 1972:122), and it can be seen, more generally, to be the point at which deviant science meets deviant religion. What unifies these diverse elements, apart from a consciousness of their deviant status and an ensuing sense of common cause, is an overlapping communication structure of magazines, pamphlets, lectures, and informal meetings, together with the common ideology of seekership."
