Please do not remove this message until conditions to do so are met. ( November 2017 ) Interpretations of the random patterns of craters on the moon. A common example of a perceptual bias caused by pareidolia. Bias is prejudice in favour of or against one thing, person, or group compared with another, usually in a way considered to be unfair. Biases can be learned implicitly within cultural contexts. People may develop biases toward or against an individual, an ethnic group, a sexual or gender identity, a nation, a religion, a social class, a political party, theoretical paradigms and ideologies within academic domains, or a species. Biased means one - sided, lacking a neutral viewpoint, or not having an open mind. Bias can come in many forms and is related to prejudice and intuition. In science and engineering, a bias is a systematic error. Statistical bias results from an unfair sampling of a population, or from an estimation process that does not give accurate results on average.

That is, a pattern of deviation from standards in judgment, whereby inferences may be created unreasonably. People create their own `` subjective social reality '' from their own perceptions, their view of the world may dictate their behaviour. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality. However some cognitive biases are taken to be adaptive, and thus may lead to success in the appropriate situation. Furthermore, cognitive biases may allow speedier choices when speed is more valuable than precision. Other cognitive biases are a `` by - product '' of human processing limitations, coming about because of an absence of appropriate mental mechanisms, or just from human limitations in information processing. Anchoring Main article : Anchoring Anchoring is a psychological heuristic that describes the propensity to rely on the first piece of information encountered when making decisions. According to this heuristic, individuals begin with an implicitly suggested reference point ( the `` anchor '' ) and make adjustments to it to reach their estimate. For example, the initial price offered for a used car sets the standard for the rest of the negotiations, so that prices lower than the initial price seem more reasonable even if they are still higher than what the car is worth. Apophenia Main articles : Apophenia and Pareidolia See also : Hindsight bias Apophenia, also known as patternicity, or agenticity, is the human tendency to perceive meaningful patterns within random data. Apophenia is well documented as a rationalization for gambling. Gamblers may imagine that they see patterns in the numbers which appear in lotteries, card games, or roulette wheels. One manifestation of this is known as the `` gambler 's fallacy ''. Pareidolia is the visual or auditory form of apophenia. It has been suggested that pareidolia combined with hierophany may have helped ancient societies organize chaos and make the world intelligible. Attribution bias Main article : Attribution bias An attribution bias can happen when individuals assess or attempt to discover explanations behind their own and others ' behaviors. People make attributions about the causes of their own and others ' behaviors ; but these attributions do n't necessarily precisely reflect reality. Rather than operating as objective perceivers, individuals are inclined to perceptual slips that prompt biased understandings of their social world. When judging others we tend to assume their actions are the result of internal factors such as personality, whereas we tend to assume our own actions arise because of the necessity of external circumstances. There are a wide range of sorts of attribution biases, such as the ultimate attribution error, fundamental attribution error, actor - observer bias, and self - serving bias. Confirmation bias Confirmation bias has been described as an internal `` yes man '', echoing back a person 's beliefs like Charles Dickens ' character Uriah Heep. Main article : Confirmation bias Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one 's beliefs or hypotheses while giving disproportionately less attention to information that contradicts it. The effect is stronger for emotionally charged issues and for deeply entrenched beliefs. People also tend to interpret ambiguous evidence as supporting their existing position. Biased search, interpretation and memory have been invoked to explain attitude polarization ( when a disagreement becomes more extreme even though the different parties are exposed to the same evidence ), belief perseverance ( when beliefs persist after the evidence for them is shown to be false ), the irrational primacy effect ( a greater reliance on information encountered early in a series ) and illusory correlation ( when people falsely perceive an association between two events or situations ). Confirmation biases contribute to overconfidence in personal beliefs and can maintain or strengthen beliefs in the face of contrary evidence. Poor decisions due to these biases have been found in political and organizational contexts. Framing Main articles : Cultural bias and Framing ( social sciences ) Framing involves the social construction of social phenomena by mass media sources, political or social movements, political leaders, and so on. It is an influence over how people organize, perceive, and communicate about reality. It can be positive or negative - depending on the audience and what kind of information is being presented. For political purposes, framing often presents facts in such a way that implicates a problem that is in need of a solution. Members of political parties attempt to frame issues in a way that makes a solution favoring their own political leaning appear as the most appropriate course of action for the situation at hand. As understood in social theory, framing is a schema of interpretation, a collection of anecdotes and stereotypes, that individuals rely on to understand and respond to events. People use filters to make sense of the world, the choices they then make are influenced by their creation of a frame. Cultural bias is the related phenomenon of interpreting and judging phenomena by standards inherent to one 's own culture. Numerous such biases exist, concerning cultural norms for color, location of body parts, mate selection, concepts of justice, linguistic and logical validity, acceptability of evidence, and taboos. Ordinary people may tend to imagine other people as basically the same, not significantly more or less valuable, probably attached emotionally to different groups and different land. Halo effect Main article : Halo effect The halo effect is when an observer 's overall impression of a person, organization, brand, or product influences their feelings about specifics of that entity 's character or properties. The name halo effect is based on the concept of the saint 's halo, and is a specific type of confirmation bias, wherein positive sentiments in one area cause questionable or unknown characteristics to be seen positively. If the observer likes one aspect of something, they will have a positive predisposition toward everything about it. A person 's appearance has been found to produce a halo effect. The halo effect is also present in the field of brand marketing, affecting perception of companies and non-governmental organizations ( NGOs ). Horn effect Main article : Horn effect Sometimes called horns effect ( as in Devil 's horns ), the horn effect is one of a number of effects that psychologists call `` Bias blind spots. '' The horn effect occurs when `` individuals believe ( that negative ) traits are inter-connected. '' This bias involves a halo effect working in a negative direction : if the observer dislikes one aspect of something, they will have a negative predisposition toward everything about it. It is a phenomenon in which an observer 's judgment of a person is adversely affected by the presence of ( for the observer ) an unfavorable aspect of this person. The term is derived from the English word `` horn '' and refers to devil 's horn ( s ). The opposite of the horn effect is called the halo effect, which is derived from the idea of the angel or saint 's halo. Both of these bias effects often clash with phrases such as `` words mean something '' and `` Your words have a history. ''. Self - serving bias Main article : Self - serving bias Self - serving bias is the tendency for cognitive or perceptual processes to be distorted by the individual 's need to maintain and enhance self - esteem. It is the propensity to credit accomplishment to our own capacities and endeavors, yet attribute failure to outside factors, to dismiss the legitimacy of negative criticism, concentrate on positive qualities and accomplishments yet disregard flaws and failures. Studies have demonstrated that this bias can affect behavior in the workplace, in interpersonal relationships, playing sports, and in consumer decisions. Status quo bias Main article : Status quo bias Status quo bias is an emotional bias ; a preference for the current state of affairs. The current baseline ( or status quo ) is taken as a reference point, and any change from that baseline is perceived as a loss. Status quo bias should be distinguished from a rational preference for the status quo ante, as when the current state of affairs is objectively superior to the available alternatives, or when imperfect information is a significant problem. A large body of evidence, however, shows that status quo bias frequently affects human decision - making. Conflicts of interest Main article : Conflict of interest A conflict of interest ( COI ) is when a person or association has intersecting interests ( financial, personal, etc. ) which could potentially corrupt. The potential conflict is autonomous of actual improper actions, it can be found and intentionally defused before corruption, or the appearance of corruption, happens. `` A conflict of interest is a set of circumstances that creates a risk that professional judgement or actions regarding a primary interest will be unduly influenced by a secondary interest. '' It exists if the circumstances are sensibly accepted to present a hazard that choices made may be unduly affected by auxiliary interests. Bribery Main article : Bribery Bribery is the giving of money, goods or other forms of recompense to in order to influence the recipient 's behavior. Bribes can include money ( including tips ), goods, rights in action, property, privilege, emolument, gifts, perks, skimming, return favors, discounts, sweetheart deals, kickbacks, funding, donations, campaign contributions, sponsorships, stock options, secret commissions, or promotions. Expectations of when a monetary transaction is appropriate can differ from place to place. Political campaign contributions in the form of cash are considered criminal acts of bribery in some countries, while in the United States they are legal provided they adhere to election law. Tipping, is considered bribery in some societies, but not others. Favoritism Main article : In - group favoritism Favoritism, sometimes known as in - group favoritism, or in - group bias, refers to a pattern of favoring members of one 's in - group over out - group members. This can be expressed in evaluation of others, in allocation of resources, and in many other ways. This has been researched by psychologists, especially social psychologists, and linked to group conflict and prejudice. Cronyism is favoritism of long - standing friends, especially by appointing them to positions of authority, regardless of their qualifications. Nepotism is favoritism granted to relatives. Funding bias Main article : Funding bias Funding bias refers to the tendency of a scientific study to support the interests of the study 's financial sponsor. This phenomenon is recognized sufficiently that researchers undertake studies to examine bias in past published studies. It can be caused by any or all of : a conscious or subconscious sense of obligation of researchers towards their employers, misconduct or malpractice, publication bias, or reporting bias. Lobbying Box offered by tobacco lobbyists to Dutch Member of the European Parliament Kartika Liotard in September 2013 Main article : Lobbying Lobbying is the attempt to influence choices made by administrators, frequently lawmakers or individuals from administrative agencies. Lobbyists may be among a legislator 's constituencies, or not ; they may engage in lobbying as a business, or not. Lobbying is often spoken of with contempt, the implication is that people with inordinate socioeconomic power are corrupting the law in order to serve their own interests. When people who have a duty to act on behalf of others, such as elected officials with a duty to serve their constituents ' interests or more broadly the common good, stand to benefit by shaping the law to serve the interests of some private parties, there is a conflict of interest. This can lead to all sides in a debate looking to sway the issue by means of lobbyists. Regulatory issues Main articles : Industry self - regulation and Regulatory capture Self - regulation is the process whereby an organization monitors its own adherence to legal, ethical, or safety standards, rather than have an outside, independent agency such as a third party entity monitor and enforce those standards. Self - regulation of any group can create a conflict of interest. If any organization, such as a corporation or government bureaucracy, is asked to eliminate unethical behavior within their own group, it may be in their interest in the short run to eliminate the appearance of unethical behavior, rather than the behavior itself. Regulatory capture is a form of political corruption that can occur when a regulatory agency, created to act in the public interest, instead advances the commercial or political concerns of special interest groups that dominate the industry or sector it is charged with regulating. Regulatory capture occurs because groups or individuals with a high - stakes interest in the outcome of policy or regulatory decisions can be expected to focus their resources and energies in attempting to gain the policy outcomes they prefer, while members of the public, each with only a tiny individual stake in the outcome, will ignore it altogether. Regulatory capture is a risk to which a regulatory agency is exposed by its very nature. Shilling Main article : Shill Shilling is deliberately giving spectators the feeling that one is an energetic autonomous client of a vendor for whom one is working. The effectiveness of shilling relies on crowd psychology to encourage other onlookers or audience members to purchase the goods or services ( or accept the ideas being marketed ). Shilling is illegal in some places, but legal in others. An example of shilling is paid reviews that give the impression of being autonomous opinions. Statistical biases Main article : Bias ( statistics ) Statistical bias is a property of a statistical technique or of its results whereby the expected value of the results differs from the true underlying quantitative parameter being estimated. Arithmetic mean is an unbiased estimator of mean and geometric mean is an example of a biased estimator of mean. Contextual biases Academic bias Main article : Academic bias Academic bias is the bias or perceived bias of scholars allowing their beliefs to shape their research and the scientific community. Claims of bias are often linked to claims by conservatives of pervasive bias against political conservatives and religious Christians. Some have argued that these claims are based upon anecdotal evidence which would not reliably indicate systematic bias, and have suggested that this divide is due to self - selection of conservatives choosing not to pursue academic careers. There is some evidence that perception of classroom bias may be rooted in issues of sexuality, race, class and sex as much or more than in religion. Educational bias Main article : Bias in education Bias in education refers to real or perceived bias in the educational system. The content of school textbooks is often the issue of debate, as their target audience is young people, and the term `` whitewashing '' is used to refer to selective removal of critical or damaging evidence or comment. Religious bias in textbooks is observed in countries where religion plays a dominant role. There can be many forms of educational bias. Some overlooked aspects, occurring especially with the pedagogical circles of public and private schools -- sources that are unrelated to fiduciary or mercantile impoverishment which may be unduly magnified -- include teacher bias as well as a general bias against women who are going into STEM research. Experimenter bias Main article : Experimenter 's bias In science research, experimenter bias occurs when experimenter expectancies regarding study results bias the research outcome. Examples of experimenter bias include conscious or unconscious influences on subject behavior including creation of demand characteristics that influence subjects, and altered or selective recording of experimental results themselves. Full text on net bias Main articles : FUTON bias and No abstract available bias Full text on net ( or FUTON ) bias is a tendency of scholars to cite academic journals with open access -- that is, journals that make their full text available on the internet without charge -- in their own writing as compared with toll access publications. Scholars can more easily discover and access articles that have their full text on the internet, which increases authors ' likelihood of reading, quoting, and citing these articles, this may increase the impact factor of open access journals relative to journals without open access. The related bias, no abstract available bias ( NAA bias ) is scholars ' tendency to cite journal articles that have an abstract available online more readily than articles that do not. Inductive bias Main article : Inductive bias Inductive bias occurs within the field of machine learning. In machine learning one seeks to develop algorithms that are able to learn to anticipate a particular output. To accomplish this, the learning algorithm is given training cases that show the expected connection. Then the learner is tested with new examples. Without further assumptions, this problem can not be solved exactly as unknown situations may not be predictable. The inductive bias of the learning algorithm is the set of assumptions that the learner uses to predict outputs given inputs that it has not encountered. It may bias the learner towards the correct solution, the incorrect, or be correct some of the time. A classical example of an inductive bias is Occam 's Razor, which assumes that the simplest consistent hypothesis is the best. Media bias Main article : Media bias Media bias is the bias or perceived bias of journalists and news producers within the mass media in the selection of events, the stories that are reported, and how they are covered. The term generally implies a pervasive or widespread bias violating the standards of journalism, rather than the perspective of an individual journalist or article. There are varied forms of media bias, including agenda - setting, gatekeeping, sensationalism, and others. The level of media bias in different nations is debated. There are also watchdog groups that report on media bias. Practical limitations to media neutrality include the inability of journalists to report all available stories and facts, the requirement that selected facts be linked into a coherent narrative, government influence including overt and covert censorship, the influence of the owners of the news source, concentration of media ownership, the selection of staff, the preferences of an intended audience, and pressure from advertisers. Bias has been a feature of the mass media since its birth with the invention of the printing press. The expense of early printing equipment restricted media production to a limited number of people. Historians have found that publishers often served the interests of powerful social groups. Publication bias Main article : Publication bias Publication bias is a type of bias with regard to what academic research is likely to be published because of a tendency of researchers, and journal editors, to prefer some outcomes rather than others e.g. results showing a significant finding, leads to a problematic bias in the published literature. This can propagate further as literature reviews of claims about support for a hypothesis will themselves be biased if the original literature is contaminated by publication bias. Studies with significant results often do not appear to be superior to studies with a null result with respect to quality of design. However, statistically significant results have been shown to be three times more likely to be published compared to papers with null results. Reporting bias & social desirability bias Main articles : Reporting bias and Social desirability bias In epidemiology and empirical research, reporting bias is defined as `` selective revealing or suppression of information '' of undesirable behavior by subjects or researchers. It refers to a tendency to under - report unexpected or undesirable experimental results, while being more trusting of expected or desirable results. This can propagate, as each instance reinforces the status quo, and later experimenters justify their own reporting bias by observing that previous experimenters reported different results. Social desirability bias is a bias within social science research where survey respondents can tend to answer questions in a manner that will be viewed positively by others. It can take the form of over-reporting laudable behavior, or under - reporting undesirable behavior. This bias interferes with the interpretation of average tendencies as well as individual differences. The inclination represents a major issue with self - report questionnaires ; of special concern are self - reports of abilities, personalities, sexual behavior, and drug use. Prejudices Main articles : Bigotry, Prejudice, and Cultural bias Bias and prejudice are usually considered to be closely related. Prejudice is prejudgment, or forming an opinion before becoming aware of the relevant facts of a case. The word is often used to refer to preconceived, usually unfavorable, judgments toward people or a person because of gender, political opinion, social class, age, disability, religion, sexuality, race / ethnicity, language, nationality, or other personal characteristics. Prejudice can also refer to unfounded beliefs and may include `` any unreasonable attitude that is unusually resistant to rational influence ''. Classism Main article : Class discrimination Classism is discrimination on the basis of social class. It includes attitudes that benefit the upper class at the expense of the lower class, or vice versa. Lookism Main article : Lookism Lookism is stereotypes, prejudice, and discrimination on the basis of physical attractiveness, or more generally to people whose appearance matches cultural preferences. Many people make automatic judgments of others based on their physical appearance that influence how they respond to those people. Racism Main article : Racism Racism consists of ideologies based on a desire to dominate or a belief in the inferiority of another race. It may also hold that members of different races should be treated differently. Sexism Main article : Sexism Sexism is discrimination based on a person 's sex or gender. Sexism can affect any gender, but it is particularly documented as affecting women and girls. It has been linked to stereotypes and gender roles, and may include the belief that one sex or gender is intrinsically superior to another.

Defines sexism as `` prejudice, stereotyping, or discrimination, typically against women, on the basis of sex. '' `` Sexism ''. Encyclopædia Britannica, Online Academic Edition. 2015. Defines sexism as `` prejudice or discrimination based on sex or gender, especially against women and girls. '' Notes that `` sexism in a society is most commonly applied against women and girls. It functions to maintain patriarchy, or male domination, through ideological and material practices of individuals, collectives, and institutions that oppress women and girls on the basis of sex or gender. '' Cudd, Ann E. ; Jones, Leslie E. ( 2005 ). `` Sexism ''. A Companion to Applied Ethics. London : Blackwell. Notes that `` ' Sexism ' refers to a historically and globally pervasive form of oppression against women. '' Masequesmay, Gina ( 2008 ). `` Sexism ''. In O'Brien, Jodi. Encyclopedia of Gender and Society. SAGE. Notes that `` sexism usually refers to prejudice or discrimination based on sex or gender, especially against women and girls. '' Also states that `` sexism is an ideology or practices that maintain patriarchy or male domination. '' Hornsby, Jennifer ( 2005 ). `` Sexism ''. In Honderich, Ted.

The Greenwood Encyclopedia of Love, Courtship, and Sexuality through History, Volume 6 : The Modern World. Greenwood. 2007. `` Sexism is any act, attitude, or institutional configuration that systematically subordinates or devalues women. Built upon the belief that men and women are constitutionally different, sexism takes these differences as indications that men are inherently superior to women, which then is used to justify the nearly universal dominance of men in social and familial relationships, as well as politics, religion, language, law, and economics.
