Bias is a disproportionate weight in favor of or against an idea or thing, usually in a way that is inaccurate, closed-minded, prejudicial, or unfair. Biases can be innate or learned. People may develop biases for or against an individual, a group, or a belief. 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.
Prejudice can be an affective feeling towards a person based on their perceived group membership. The word is often used to refer to a preconceived evaluation or classification of another person based on that person's perceived personal characteristics, such as political affiliation, sex, gender, gender identity, beliefs, values, social class, age, disability, religion, sexuality, race, ethnicity, language, nationality, culture, complexion, beauty, height, body weight, occupation, wealth, education, criminality, sport-team affiliation, music tastes or other perceived characteristics.
In-group favoritism, sometimes known as in-group–out-group bias, in-group bias, intergroup bias, or in-group preference, is 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.
The implicit-association test (IAT) is an assessment intended to detect subconscious associations between mental representations of objects (concepts) in memory. Its best-known application is the assessment of implicit stereotypes held by test subjects, such as associations between particular racial categories and stereotypes about those groups. The test has been applied to a variety of belief associations, such as those involving racial groups, gender, sexuality, age, and religion but also the self-esteem, political views, and predictions of the test taker. The implicit-association test is the subject of significant academic and popular debate regarding its validity, reliability, and usefulness in assessing implicit bias.
Social dominance orientation (SDO) is a personality trait measuring an individual's support for social hierarchy and the extent to which they desire their in-group be superior to out-groups. SDO is conceptualized under social dominance theory as a measure of individual differences in levels of group-based discrimination; that is, it is a measure of an individual's preference for hierarchy within any social system and the domination over lower-status groups. It is a predisposition toward anti-egalitarianism within and between groups.
Laurie A. Rudman is a social psychology feminist professor as well as the Director of the Rutgers University Social Cognition Laboratory who has contributed a great deal of research to studies on implicit and explicit attitudes and stereotypes, stereotype maintenance processes, and the media's effects on attitudes, stereotypes, and behavior on the Feminism movement. She was awarded the 1994 Gordon Allport Intergroup Relations Prize for her research examining the effects of sexist advertising on men's behavior toward female job applicants.
Aversive racism is a social scientific theory proposed by Samuel L. Gaertner & John F. Dovidio (1986), according to which negative evaluations of racial/ethnic minorities are realized by a persistent avoidance of interaction with other racial and ethnic groups. As opposed to traditional, overt racism, which is characterized by overt hatred for and discrimination against racial/ethnic minorities, aversive racism is characterized by more complex, ambivalent expressions and attitudes nonetheless with prejudicial views towards other races. Aversive racism arises from unconscious personal beliefs taught during childhood. Subtle racist behaviors are usually targeted towards African Americans. Workplace discrimination is one of the best examples of aversive racism. Biased beliefs on how minorities act and think affect how individuals interact with minority members.
In social psychology, a stereotype is a generalized belief about a particular category of people. It is an expectation that people might have about every person of a particular group. The type of expectation can vary; it can be, for example, an expectation about the group's personality, preferences, appearance or ability. Stereotypes are often overgeneralized, inaccurate, and resistant to new information. A stereotype does not necessarily need to be a negative assumption. They may be positive, neutral, or negative.
Implicit attitudes are evaluations that occur without conscious awareness towards an attitude object or the self. These evaluations are generally either favorable or unfavorable and come about from various influences in the individual experience. The commonly used definition of implicit attitude within cognitive and social psychology comes from Anthony Greenwald and Mahzarin Banaji's template for definitions of terms related to implicit cognition: "Implicit attitudes are introspectively unidentified traces of past experience that mediate favorable or unfavorable feeling, thought, or action toward social objects". These thoughts, feelings or actions have an influence on behavior that the individual may not be aware of.
Ambivalent sexism is a theoretical framework which posits that sexism has two sub-components: "hostile sexism" (HS) and "benevolent sexism" (BS). Hostile sexism reflects overtly negative evaluations and stereotypes about a gender. Benevolent sexism represents evaluations of gender that may appear subjectively positive, but are actually damaging to people and gender equality more broadly. For the most part, psychologists have studied hostile forms of sexism. However, theorists using the theoretical framework of ambivalent sexism have found extensive empirical evidence for both varieties. The theory has largely been developed by social psychologists Peter Glick and Susan Fiske.
Expectation states theory is a social psychological theory first proposed by Joseph Berger and his colleagues that explains how expected competence forms the basis for status hierarchies in small groups. The theory's best known branch, status characteristics theory, deals with the role that certain pieces of social information play in organizing these hierarchies. More recently, sociologist Cecilia Ridgeway has utilized the theory to explain how beliefs about status become attached to different social groups and the implications this has for social inequality.
Ambivalent prejudice is a social psychological theory that states that, when people become aware that they have conflicting beliefs about an outgroup, they experience an unpleasant mental feeling generally referred to as cognitive dissonance. These feelings are brought about because the individual on one hand believes in humanitarian virtues such as helping those in need, but on the other hand also believes in individualistic virtues such as working hard to improve one's life.
Benevolent prejudice is a superficially positive prejudice expressed in terms of positive beliefs and emotional responses, which are associated with hostile prejudices or result in keeping affected groups in inferior societal positions. Benevolent prejudice can be expressed towards those of different race, religion, ideology, country, sex, sexual orientation, or gender identity.
Role congruity theory proposes that a group will be positively evaluated when its characteristics are recognized as aligning with that group's typical social roles. Conversely, the stereotype fit hypothesis suggests that group members will experience discrimination in different social roles or positions to the extent that their group stereotypically does not have characteristics associated with success in the position. For instance, women may not be considered a good fit for a managerial position if being aggressive is seen as a characteristic of a successful manager. Due to stereotype fit, men may be considered more qualified for the position and are not only more likely to be hired, but are also more likely to be promoted as well.
An implicit bias or implicit stereotype is the pre-reflective attribution of particular qualities by an individual to a member of some social out group. Recent studies have determined that "implicit bias" towards those of the opposite gender may be even more influential than racial implicit bias.

Nilanjana Dasgupta is a social psychologist whose work focuses on the effects of social contexts on implicit stereotypes - particularly on factors that insulate women in STEM fields from harmful stereotypes which suggest that females perform poorly in such areas. Dasgupta is a professor of Psychology and is the Director of the Institute of Diversity Sciences and the University of Massachusetts, Amherst.
Implicit bias training programs are designed to help individuals become aware of their implicit biases and equip them with tools and strategies to act objectively, limiting the influence of their implicit biases. Some researchers say implicit biases are learned stereotypes that are automatic, seemingly associative, unintentional, deeply ingrained, universal, and can influence behavior.
In social psychology, a metastereotype is a stereotype that members of one group have about the way in which they are stereotypically viewed by members of another group. In other words, it is a stereotype about a stereotype. They have been shown to have adverse effects on individuals that hold them, including on their levels of anxiety in interracial conversations. Meta-stereotypes held by African Americans regarding the stereotypes White Americans have about them have been found to be largely both negative and accurate. People portray meta-stereotypes of their ingroup more positively when talking to a member of an outgroup than to a fellow member of their ingroup.
Outgroup favoritism is a social psychological construct intended to capture why some socially disadvantaged groups will express favorable attitudes toward social, cultural, or ethnic groups other than their own. Considered by many psychologists as part of a variety of system-justifying motives, outgroup favoritism has been widely researched as a potential explanation for why groups—particularly those disadvantaged by the normative social hierarchy—are motivated to support, maintain, and preserve the status quo. Specifically, outgroup favoritism provides a contrast to the idea of ingroup favoritism, which proposes that individuals exhibit a preference for members of their own group over members of the outgroup.
