: both evidence against the conspiracy ''and'' absence of evidence for it are misinterpreted as evidence of its truth. Stephan Lewandowsky observes "This interpretation relies on the notion that, the stronger the evidence against a conspiracy, the more the conspirators must want people to believe their version of events." As a consequence, the conspiracy becomes a matter of faith rather than something that can be proven or disproven. Studies have linked belief in conspiracy theories to distrust of authority and political cynicism. Some researchers suggest that conspiracist ideation—belief in conspiracy theories—may be psychologically harmful or pathological. Such belief is correlated with

. However, a 2020 review article found that most cognitive scientists view conspiracy theorizing as typically nonpathological, given that unfounded belief in conspiracy is common across both historical and contemporary cultures, and may arise from innate human tendencies towards gossip, group cohesion, and religion. One historical review of conspiracy theories concluded that "Evidence suggests that the aversive feelings that people experience when in crisis—fear, uncertainty, and the feeling of being out of control—stimulate a motivation to make sense of the situation, increasing the likelihood of perceiving conspiracies in social situations." Historically, conspiracy theories have been closely linked to

He used it to refer to claims that British aristocrats were intentionally weakening the United States during the American Civil War in order to advance their financial interests. The term is also used as a way to discredit dissenting analyses. Robert Blaskiewicz comments that examples of the term were used as early as the nineteenth century and states that its usage has always been derogatory. According to a study by Andrew McKenzie-McHarg, in contrast, in the nineteenth century the term ''conspiracy theory'' simply "suggests a plausible postulate of a conspiracy" and "did not, at this stage, carry any connotations, either negative or positive", though sometimes a postulate so-labeled was criticized.

describes a conspiracy theory as a "template imposed upon the world to give the appearance of order to events". Real conspiracies, even very simple ones, are difficult to conceal and routinely experience unexpected problems. In contrast, conspiracy theories suggest that conspiracies are unrealistically successful and that groups of conspirators, such as bureaucracies, can act with near-perfect competence and secrecy. The causes of events or situations are simplified to exclude complex or interacting factors, as well as the role of chance and unintended consequences. Nearly all observations are explained as having been deliberately planned by the alleged conspirators. In conspiracy theories, the conspirators are usually claimed to be acting with extreme malice. As described by Robert Brotherton:

A conspiracy theory may take any matter as its subject, but certain subjects attract greater interest than others. Favored subjects include famous deaths and assassinations, morally dubious government activities, suppressed technologies, and "

Popularity

Conspiracy beliefs are widespread around the world. In rural Africa, common targets of conspiracy theorizing include societal elites, enemy tribes, and the Western world, with conspirators often alleged to enact their plans via sorcery or witchcraft; one common belief identifies modern technology as itself being a form of sorcery, created with the goal of harming or controlling the people. In China, one widely published conspiracy theory claims that a number of events including the rise of Hitler, the

in the United States of the late 20th and early 21st centuries. The general predisposition to believe conspiracy theories cuts across partisan and ideological lines. Conspiratorial thinking is correlated with antigovernmental orientations and a low sense of political efficacy, with conspiracy believers perceiving a governmental threat to individual rights and displaying a deep skepticism that who one votes for really matters. Conspiracy theories are often commonly believed, some even being held by the majority of the population. A broad cross-section of Americans today gives credence to at least some conspiracy theories. For instance, a study conducted in 2016 found that 10% of Americans think the chemtrail conspiracy theory is "completely true" and 20–30% think it is "somewhat true". This puts "the equivalent of 120 million Americans in the 'chemtrails are real' camp". Belief in conspiracy theories has therefore become a topic of interest for sociologists, psychologists and experts in

Types

A conspiracy theory can be local or international, focused on single events or covering multiple incidents and entire countries, regions and periods of history. According to Russell Muirhead and Nancy Rosenblum, historically, traditional conspiracism has entailed a "theory", but over time, "conspiracy" and "theory" have become decoupled, as modern conspiracism is often without any kind of theory behind it.


Walker's five kinds

Jesse Walker (2013) has identified five kinds of conspiracy theories: * The "Enemy Outside" refers to theories based on figures alleged to be scheming against a community from without. * The "Enemy Within" finds the conspirators lurking inside the nation, indistinguishable from ordinary citizens. * The "Enemy Above" involves powerful people manipulating events for their own gain. * The "Enemy Below" features the lower classes working to overturn the social order. * The "Benevolent Conspiracies" are angelic forces that work behind the scenes to improve the world and help people.

?'' ("Who benefits?"), jumping to the conclusion that a posited beneficiary is responsible for covertly influencing events. On the other hand, the "deep" conspiracy theorist begins with a hunch and then seeks out evidence. Rothbard describes this latter activity as a matter of confirming with certain facts one's initial paranoia.


Lack of evidence

Belief in conspiracy theories is generally based not on evidence but on the faith of the believer.

The Watergate scandal serves as the standard reference." By contrast, the term "Watergate conspiracy theory" is used to refer to a variety of hypotheses in which those convicted in the conspiracy were in fact the victims of a deeper conspiracy. There are also attempts to analyze the theory of conspiracy theories (conspiracy theory theory) to ensure that the term "conspiracy theory" is used to refer to narratives that have been debunked by experts, rather than as a generalized dismissal.

Conspiracy theories are most successful when proponents can gather followers from the general public, such as in politics, religion and journalism.

Conspiratorial claims can act as a successful rhetorical strategy to convince a portion of the public via

is used by conspiracy theorists: both evidence against the conspiracy and an absence of evidence for it are re-interpreted as evidence of its truth, whereby the conspiracy becomes a matter of faith rather than something that can be proved or disproved. The epistemic strategy of conspiracy theories has been called "cascade logic": each time new evidence becomes available, a conspiracy theory is able to dismiss it by claiming that even more people must be part of the cover-up. Any information that contradicts the conspiracy theory is suggested to be disinformation by the alleged conspiracy. Similarly, the continued lack of evidence directly supporting conspiracist claims is portrayed as confirming the existence of a conspiracy of silence; the fact that other people have not found or exposed any conspiracy is taken as evidence that those people are part of the plot, rather than considering that it may be because no conspiracy exists. This strategy lets conspiracy theories insulate themselves from neutral analyses of the evidence, and makes them resistant to questioning or correction, which is called "epistemic self-insulation". Conspiracy theorists often take advantage of

s'' and attacking perceived flaws in the mainstream account, while avoiding any discussion of the shortcomings in their own position. The typical approach of conspiracy theories is to challenge any action or statement from authorities, using even the most tenuous justifications. Responses are then assessed using a double standard, where failing to provide an immediate response to the satisfaction of the conspiracy theorist will be claimed to prove a conspiracy. Any minor errors in the response are heavily emphasized, while deficiencies in the arguments of other proponents are generally excused. In science, conspiracists may suggest that a

and far left. More generally, belief in conspiracy theories is associated with holding extreme and uncompromising viewpoints, and may help people in maintaining those viewpoints. While conspiracy theories are not always present in extremist groups, and do not always lead to violence when they are, they can make the group more extreme, provide an enemy to direct hatred towards, and isolate members from the rest of society. Conspiracy theories are most likely to inspire violence when they call for urgent action, appeal to prejudices, or demonize and scapegoat enemies. Conspiracy theorizing in the workplace can also have economic consequences. For example, it leads to lower job satisfaction and lower commitment, resulting in workers being more likely to leave their jobs. Comparisons have also been made with the effects of workplace rumors, which share some characteristics with conspiracy theories and result in both decreased productivity and increased stress. Subsequent effects on managers include reduced profits, reduced trust from employees, and damage to the company's image. Conspiracy theories can divert attention from important social, political, and scientific issues. In addition, they have been used to discredit scientific evidence to the general public or in a legal context. Conspiratorial strategies also share characteristics with those used by lawyers who are attempting to discredit expert testimony, such as claiming that the experts have ulterior motives in testifying, or attempting to find someone who will provide statements to imply that expert opinion is more divided than it actually is. It is possible that conspiracy theories may also produce some compensatory benefits to society in certain situations. For example, they may help people identify governmental deceptions, particularly in repressive societies, and encourage government transparency. However, real conspiracies are normally revealed by people working within the system, such as

Interventions


Target audience

Strategies to address conspiracy theories have been divided into two categories based on whether the target audience is the conspiracy theorists or the general public. These strategies have been described as reducing either the supply or the demand for conspiracy theories. Both approaches can be used at the same time, although there may be issues of limited resources, or if arguments are used which may appeal to one audience at the expense of the other. Brief scientific literacy interventions, particularly those focusing on critical thinking skills, can effectively undermine conspiracy beliefs and related behaviors. Research led by Penn State scholars, published in the ''

'', found that enhancing scientific knowledge and reasoning through short interventions, such as videos explaining concepts like correlation and causation, reduces the endorsement of conspiracy theories. These interventions were most effective against conspiracy theories based on faulty reasoning and were successful even among groups prone to conspiracy beliefs. The studies, involving over 2,700 participants, highlight the importance of educational interventions in mitigating conspiracy beliefs, especially when timed to influence critical decision-making.


General public

People who feel empowered are more resistant to conspiracy theories. Methods to promote empowerment include encouraging people to use analytical thinking, priming people to think of situations where they are in control, and ensuring that decisions by society and government are seen to follow procedural fairness (the use of fair decision-making procedures). Methods of refutation which have shown effectiveness in various circumstances include: providing facts that demonstrate the conspiracy theory is false, attempting to discredit the source, explaining how the logic is invalid or misleading, and providing links to fact-checking websites. It can also be effective to use these strategies in advance, informing people that they could encounter misleading information in the future, and why the information should be rejected (also called inoculation or prebunking). While it has been suggested that discussing conspiracy theories can raise their profile and make them seem more legitimate to the public, the discussion can put people on guard instead as long as it is sufficiently persuasive. Other approaches to reduce the appeal of conspiracy theories in general among the public may be based in the emotional and social nature of conspiratorial beliefs. For example, interventions that promote analytical thinking in the general public are likely to be effective. Another approach is to intervene in ways that decrease

Conspiracy theorists

It is much more difficult to convince people who already believe in conspiracy theories. Conspiracist belief systems are not based on external evidence, but instead use
circular logic Circular reasoning (, "circle in proving"; also known as circular logic) is a logical fallacy in which the reasoner begins with what they are trying to end with. Circular reasoning is not a formal logical fallacy, but a pragmatic defect in an ar ...
where every belief is supported by other conspiracist beliefs. In addition, conspiracy theories have a "self-sealing" nature, in which the types of arguments used to support them make them resistant to questioning from others. Characteristics of successful strategies for reaching conspiracy theorists have been divided into several broad categories: 1) Arguments can be presented by "trusted messengers", such as people who were formerly members of an extremist group. 2) Since conspiracy theorists think of themselves as people who value critical thinking, this can be affirmed and then redirected to encourage being more critical when analyzing the conspiracy theory. 3) Approaches demonstrate empathy, and are based on building understanding together, which is supported by modeling open-mindedness in order to encourage the conspiracy theorists to do likewise. 4) The conspiracy theories are not attacked with ridicule or aggressive deconstruction, and interactions are not treated like an argument to be won; this approach can work with the general public, but among conspiracy theorists it may simply be rejected. Interventions that reduce feelings of uncertainty, anxiety, or powerlessness result in a reduction in conspiracy beliefs. Other possible strategies to mitigate the effect of conspiracy theories include education, media literacy, and increasing governmental openness and transparency. Due to the relationship between conspiracy theories and political extremism, the academic literature on
deradicalization Deradicalization refers to a process of encouraging a person with extreme political, social or religious views to adopt more moderate positions on the issues. Measures and projects Google's think tank Jigsaw has been developing a new program ...
is also important. One approach describes conspiracy theories as resulting from a "crippled epistemology", in which a person encounters or accepts very few relevant sources of information. A conspiracy theory is more likely to appear justified to people with a limited "informational environment" who only encounter misleading information. These people may be " epistemologically isolated" in self-enclosed networks. From the perspective of people within these networks, disconnected from the information available to the rest of society, believing in conspiracy theories may appear to be justified. In these cases, the solution would be to break the group's informational isolation.


Reducing transmission

Public exposure to conspiracy theories can be reduced by interventions that reduce their ability to spread, such as by encouraging people to reflect before sharing a news story. Researchers Carlos Diaz Ruiz and Tomas Nilsson have proposed technical and rhetorical interventions to counter the spread of conspiracy theories on social media.


Government policies

The primary defense against conspiracy theories is to maintain an
open society Open society () is a term coined by French-Jewish philosopher Henri Bergson in 1932, and describes a dynamic system inclined to moral universalism.Thomas Mautner (2005), 2nd ed. ''The Penguin Dictionary of Philosophy'' Open society" entry p. ...

reduces the number of information sources available to the population, which may lead people to support conspiracy theories. Since the credibility of conspiracy theories can be increased if governments act dishonestly or otherwise engage in objectionable actions, avoiding such actions is also a relevant strategy. Joseph Pierre has said that mistrust in authoritative institutions is the core component underlying many conspiracy theories and that this mistrust creates an epistemic vacuum and makes individuals searching for answers vulnerable to misinformation. Therefore, one possible solution is offering consumers a seat at the table to mend their mistrust in institutions. Regarding the challenges of this approach, Pierre has said, "The challenge with acknowledging areas of uncertainty within a public sphere is that doing so can be weaponized to reinforce a post-truth view of the world in which everything is debatable, and any counter-position is just as valid. Although I like to think of myself as a middle of the road kind of individual, it is important to keep in mind that the truth does not always lie in the middle of a debate, whether we are talking about climate change, vaccines, or antipsychotic medications." Researchers have recommended that public policies should take into account the possibility of conspiracy theories relating to any policy or policy area, and prepare to combat them in advance. Conspiracy theories have suddenly arisen in the context of policy issues as disparate as land-use laws and bicycle-sharing programs. In the case of public communications by government officials, factors that improve the effectiveness of communication include using clear and simple messages, and using messengers which are trusted by the target population. Government information about conspiracy theories is more likely to be believed if the messenger is perceived as being part of someone's
in-group In social psychology and sociology, an in-group is a social group to which a person psychologically identifies as being a member. By contrast, an out-group is a social group with which an individual does not identify. People may for example ...
. Official representatives may be more effective if they share characteristics with the target groups, such as ethnicity. In addition, when the government communicates with citizens to combat conspiracy theories, online methods are more efficient compared to other methods such as print publications. This also promotes transparency, can improve a message's perceived trustworthiness, and is more effective at reaching underrepresented demographics. However, , many governmental websites do not take full advantage of the available information-sharing opportunities. Similarly, social media accounts need to be used effectively in order to achieve meaningful communication with the public, such as by responding to requests that citizens send to those accounts. Other steps include adapting messages to the communication styles used on the social media platform in question, and promoting a culture of openness. Since mixed messaging can support conspiracy theories, it is also important to avoid conflicting accounts, such as by ensuring the accuracy of messages on the social media accounts of individual members of the organization.


Public health campaigns

Successful methods for dispelling conspiracy theories have been studied in the context of
public health Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the de ...
campaigns. A key characteristic of communication strategies to address medical conspiracy theories is the use of techniques that rely less on emotional appeals. It is more effective to use methods that encourage people to process information rationally. The use of visual aids is also an essential part of these strategies. Since conspiracy theories are based on intuitive thinking, and visual information processing relies on intuition, visual aids are able to compete directly for the public's attention. In public health campaigns, information retention by the public is highest for loss-framed messages that include more extreme outcomes. However, excessively appealing to catastrophic scenarios (e.g. low vaccination rates causing an epidemic) may provoke anxiety, which is associated with conspiracism and could increase belief in conspiracy theories instead. Scare tactics have sometimes had mixed results, but are generally considered ineffective. An example of this is the use of images that showcase disturbing health outcomes, such as the impact of smoking on dental health. One possible explanation is that information processed via the fear response is typically not evaluated rationally, which may prevent the message from being linked to the desired behaviors. A particularly important technique is the use of
focus group A focus group is a group interview involving a small number (sometimes up to ten) of demographically predefined participants. Their reactions to specific researcher/evaluator-posed questions are studied. Focus groups are used in market researc ...
s to understand exactly what people believe, and the reasons they give for those beliefs. This allows messaging to focus on the specific concerns that people identify, and on topics that are easily misinterpreted by the public, since these are factors which conspiracy theories can take advantage of. In addition, discussions with focus groups and observations of the group dynamics can indicate which anti-conspiracist ideas are most likely to spread. Interventions that address medical conspiracy theories by reducing powerlessness include emphasizing the principle of
informed consent Informed consent is an applied ethics principle that a person must have sufficient information and understanding before making decisions about accepting risk. Pertinent information may include risks and benefits of treatments, alternative treatme ...
, giving patients all the relevant information without imposing decisions on them, to ensure that they have a sense of control. Improving access to healthcare also reduces medical conspiracism. However, doing so by political efforts can also fuel additional conspiracy theories, which occurred with the
Affordable Care Act The Affordable Care Act (ACA), formally known as the Patient Protection and Affordable Care Act (PPACA) and informally as Obamacare, is a landmark U.S. federal statute enacted by the 111th United States Congress and signed into law by Presid ...
(Obamacare) in the United States. Another successful strategy is to require people to watch a short video when they fulfil requirements such as registration for school or a drivers' license, which has been demonstrated to improve vaccination rates and signups for organ donation. Another approach is based on viewing conspiracy theories as narratives which express personal and cultural values, making them less susceptible to straightforward factual corrections, and more effectively addressed by counter-narratives. Counter-narratives can be more engaging and memorable than simple corrections, and can be adapted to the specific values held by individuals and cultures. These narratives may depict personal experiences, or alternatively they can be cultural narratives. In the context of vaccination, examples of cultural narratives include stories about scientific breakthroughs, about the world before vaccinations, or about heroic and altruistic researchers. The themes to be addressed would be those that could be exploited by conspiracy theories to increase
vaccine hesitancy Vaccine hesitancy is a delay in acceptance, or refusal of vaccines despite availability and supporting evidence. The term covers refusals to vaccinate, delaying vaccines, accepting vaccines but remaining uncertain about their use, or using ce ...

Backfire effects

can be counterproductive. For example, since conspiracy theories can reinterpret disconfirming information as part of their narrative, refuting a claim can result in accidentally reinforcing it, which is referred to as a "backfire effect". In addition, publishing criticism of conspiracy theories can result in legitimizing them. In this context, possible interventions include carefully selecting which conspiracy theories to refute, requesting additional analyses from independent observers, and introducing cognitive diversity into conspiratorial communities by undermining their poor epistemology. Any legitimization effect might also be reduced by responding to more conspiracy theories rather than fewer. There are psychological mechanisms by which backfire effects could potentially occur, but the evidence on this topic is mixed, and backfire effects are very rare in practice. A 2020 review of the scientific literature on backfire effects found that there have been widespread failures to replicate their existence, even under conditions that would be theoretically favorable to observing them. Due to the lack of
reproducibility Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the scientific method. For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or ...
, most researchers believe that backfire effects are either unlikely to occur on the broader population level, or they only occur in very specific circumstances, or they do not exist. Brendan Nyhan, one of the researchers who initially proposed the occurrence of backfire effects, wrote in 2021 that the persistence of misinformation is most likely due to other factors. In general, people do reject conspiracy theories when they learn about their contradictions and lack of evidence. For most people, corrections and fact-checking are very unlikely to have a negative impact, and there is no specific group of people in which backfire effects have been consistently observed. Presenting people with factual corrections, or highlighting the logical contradictions in conspiracy theories, has been demonstrated to have a positive effect in many circumstances. For example, this has been studied in the case of informing believers in 9/11 conspiracy theories about statements by actual experts and witnesses. One possibility is that criticism is most likely to backfire if it challenges someone's worldview or identity. This suggests that an effective approach may be to provide criticism while avoiding such challenges.


Psychology

The widespread belief in conspiracy theories has become a topic of interest for sociologists, psychologists, and experts in folklore since at least the 1960s, when a number of conspiracy theories arose regarding the assassination of U.S. President
John F. Kennedy John Fitzgerald Kennedy (May 29, 1917 – November 22, 1963), also known as JFK, was the 35th president of the United States, serving from 1961 until his assassination in 1963. He was the first Roman Catholic and youngest person elected p ...
. Sociologist Türkay Salim Nefes underlines the political nature of conspiracy theories. He suggests that one of the most important characteristics of these accounts is their attempt to unveil the "real but hidden" power relations in social groups. The term "conspiracism" was popularized by academic Frank P. Mintz in the 1980s. According to Mintz, conspiracism denotes "belief in the primacy of conspiracies in the unfolding of history": Research suggests, on a psychological level, conspiracist ideation—belief in conspiracy theories—can be harmful or pathological, and is highly correlated with

of the late 20th and early 21st centuries. Exposure to conspiracy theories in news media and popular entertainment increases receptiveness to conspiratorial ideas, and has also increased the social acceptability of fringe beliefs. Conspiracy theories often use complicated and detailed arguments, including ones that appear analytical or scientific. However, belief in conspiracy theories is primarily driven by emotion. One of the most widely confirmed facts about conspiracy theories is that belief in a single conspiracy theory is often associated with belief in other conspiracy theories. This even applies when the conspiracy theories directly contradict each other—e.g., believing that

was already dead before his compound in Pakistan was attacked makes the same person more likely to believe that he is still alive. One conclusion from this finding is that the content of a conspiracist belief is less important than the idea of a coverup by the authorities. Analytical thinking aids in reducing belief in conspiracy theories, in part because it emphasizes rational and critical cognition. Some psychological scientists assert that explanations related to conspiracy theories can be, and often are, "internally consistent" with strong beliefs previously held prior to the event that sparked the belief in a conspiracy. People who believe in conspiracy theories tend to believe in other unsubstantiated claims, including

Attractions

Psychological motives for believing in conspiracy theories can be categorized as epistemic, existential, or social. These motives are particularly acute in vulnerable and disadvantaged populations. However, it does not appear that the beliefs help to address these motives; in fact, they may be self-defeating, acting to make the situation worse instead. For example, while conspiratorial beliefs can result from a perceived sense of powerlessness, exposure to conspiracy theories immediately suppresses personal feelings of autonomy and control. Furthermore, they also make people less likely to take actions that could improve their circumstances. This is additionally supported by the fact that conspiracy theories have a number of disadvantageous attributes. For example, they promote a hostile and distrustful view of other people and groups allegedly acting based on antisocial and cynical motivations. This is expected to lead to increased

. His research suggests that the smaller the minority believing in a specific theory, the more attractive it is to conspiracy theorists. Humanistic psychologists argue that even if a posited cabal behind an alleged conspiracy is almost always perceived as hostile, there often remains an element of reassurance for theorists. This is because it is a consolation to imagine that humans create difficulties in human affairs and remain within human control. If a cabal can be implicated, there may be a hope of breaking its power or of joining it. Belief in the power of a cabal is an implicit assertion of human dignity—an unconscious affirmation that man is responsible for his own destiny. People formulate conspiracy theories to explain, for example, power relations in social groups and the perceived existence of evil forces. Proposed psychological origins of conspiracy theorising include projection; the personal need to explain "a significant event

, unpredictable, or otherwise inexplicable events. According to Berlet and Lyons, "Conspiracism is a particular narrative form of scapegoating that frames demonized enemies as part of a vast insidious plot against the common good, while it valorizes the scapegoater as a hero for sounding the alarm".


Causes

Some psychologists believe that a search for meaning is common in conspiracism. Once cognized,

may reinforce the belief. When a conspiracy theory has become embedded within a social group, communal reinforcement may also play a part. Inquiry into possible motives behind the accepting of irrational conspiracy theories has linked these beliefs to distress resulting from an event that occurred, such as the events of 9/11. Additional research suggests that "delusional ideation" is the trait most likely to indicate a stronger belief in conspiracy theories. Research also shows an increased attachment to these irrational beliefs leads to a decreased desire for civic engagement. Belief in conspiracy theories is correlated with low intelligence, lower analytical thinking,

and her book ''Virtues of the Mind'' in outlining intellectual virtues (such as humility, caution, and carefulness) and intellectual vices (such as gullibility, carelessness, and closed-mindedness). Whereas intellectual virtues help reach sound examination, intellectual vices "impede effective and responsible inquiry", meaning that those prone to believing in conspiracy theories possess certain vices while lacking necessary virtues. Some researchers have suggested that conspiracy theories could be partially caused by the human brain's mechanisms for detecting dangerous coalitions. Such a mechanism could have been helpful in the small-scale environment humanity evolved in but is mismatched in a modern, complex society and thus "misfire", perceiving conspiracies where none exist.

is prevalent amongst conspiracy theorists. According to the argument, this projection is manifested in the form of attributing undesirable characteristics of the self to the conspirators. Historian Richard Hofstadter stated that: Hofstadter also noted that "sexual freedom" is a vice frequently attributed to the conspiracist's target group, noting that "very often the fantasies of true believers reveal strong sadomasochistic outlets, vividly expressed, for example, in the delight of anti-Masons with the cruelty of Masonic punishments".


Physiology

Marcel Danesi suggests that people who believe conspiracy theories have difficulty rethinking situations. Exposure to those theories has caused neural pathways to be more rigid and less subject to change. Initial susceptibility to believing these theories' lies, dehumanizing language, and metaphors leads to the acceptance of larger and more extensive theories because the hardened neural pathways are already present. Repetition of the "facts" of conspiracy theories and their connected lies simply reinforces the rigidity of those pathways. Thus, conspiracy theories and dehumanizing lies are not mere hyperbole; they can actually change the way people think:


Sociology

In addition to psychological factors such as conspiracist ideation, sociological factors also help account for who believes in which conspiracy theories. Such theories tend to get more traction among election losers in society, for example, and the emphasis on conspiracy theories by elites and leaders tends to increase belief among followers with higher levels of conspiracy thinking.

Viability

As evidence that undermines an alleged conspiracy grows, the number of alleged conspirators also grows in the minds of conspiracy theorists. This is because of an assumption that the alleged conspirators often have competing interests. For example, if Republican President
George W. Bush George Walker Bush (born July 6, 1946) is an American politician and businessman who was the 43rd president of the United States from 2001 to 2009. A member of the Bush family and the Republican Party (United States), Republican Party, he i ...
is allegedly responsible for the 9/11 terrorist attacks, and the Democratic party did not pursue exposing this alleged plot, that must mean that both the Democratic and Republican parties are conspirators in the alleged plot. It also assumes that the alleged conspirators are so competent that they can fool the entire world, but so incompetent that even the unskilled conspiracy theorists can find mistakes they make that prove the fraud. At some point, the number of alleged conspirators, combined with the contradictions within the alleged conspirators' interests and competence, becomes so great that maintaining the theory becomes an obvious exercise in absurdity. The physicist David Robert Grimes estimated the time it would take for a conspiracy to be exposed based on the number of people involved. His calculations used data from the

Grimes estimated that: * A Moon landing hoax would require the involvement of 411,000 people and would be exposed within 3.68 years; * Climate-change fraud would require a minimum of 29,083 people (published climate scientists only) and would be exposed within 26.77 years, or up to 405,000 people, in which case it would be exposed within 3.70 years; * A vaccination conspiracy would require a minimum of 22,000 people (without drug companies) and would be exposed within at least 3.15 years and at most 34.78 years depending on the number involved; * A conspiracy to suppress a cure for cancer would require 714,000 people and would be exposed within 3.17 years. Grimes's study did not consider exposure by sources outside of the alleged conspiracy. It only considered exposure from within the alleged conspiracy through whistleblowers or through incompetence.

attacks, to support the existence of unverified and ongoing large-scale conspiracies. In his studies of "American political demonology", historian Michael Paul Rogin too analyzed this paranoid style of politics that has occurred throughout American history. Conspiracy theories frequently identify an imaginary subversive group that is supposedly attacking the nation and requires the government and allied forces to engage in harsh extra-legal repression of those threatening subversives. Rogin cites examples from the Red Scares of 1919 to McCarthy's anti-communist campaign in the 1950s and, more recently, fears of immigrant hordes invading the US. Unlike Hofstadter, Rogin saw these "countersubversive" fears as frequently coming from those in power and dominant groups instead of from the dispossessed. Unlike Robert Jewett, Rogin blamed not the counterculture but America's dominant culture of liberal individualism and the fears it stimulated to explain the periodic eruption of irrational conspiracy theories.
