Discrimination
View on Wikipedia

Discrimination is the process of making prejudicial distinctions between people based on the groups, classes, or other categories to which they belong or are perceived to belong,[1] such as race, gender, age, class, religion, disability or sexual orientation.[2] Discrimination typically leads to groups being unfairly treated on the basis of perceived statuses of characteristics, for example ethnic, racial, gender or religious categories.[2][3] It involves depriving members of one group of opportunities or privileges that are available to members of another group.[4]
Discriminatory traditions, policies, ideas, practices and laws exist in many countries and institutions in all parts of the world, including some, where such discrimination is generally decried. In some places, countervailing measures such as quotas have been used to redress the balance in favor of those who are believed to be current or past victims of discrimination. These attempts have often been met with controversy, and sometimes been called reverse discrimination.[5]
Etymology
[edit]The term discriminate appeared in the early 17th century in the English language. It is from the Latin discriminat- 'distinguished between', from the verb discriminare, from discrimen 'distinction', from the verb discernere (corresponding to "to discern").[6] Since the American Civil War the term "discrimination" generally evolved in American English usage as an understanding of prejudicial treatment of an individual based solely on their race, later generalized as membership in a certain socially undesirable group or social category.[7] Before this sense of the word became almost universal, it was a synonym for discernment, tact and culture as in "taste and discrimination", generally a laudable attribute; to "discriminate against" being commonly disparaged.[8][9][page needed]
Definitions
[edit]Moral philosophers[who?] have defined[when?] discrimination using a moralized definition. Under this approach, discrimination is defined as acts, practices, or policies that wrongfully impose a relative disadvantage or deprivation on persons based on their membership in a salient social group.[10] This is a comparative definition. An individual need not be actually harmed in order to be discriminated against. They just need to be treated worse than others for some arbitrary reason. If someone decides to donate to help orphan children, but decides to donate less, say, to children of a particular race out of a racist attitude, they will be acting in a discriminatory way even if they actually benefit the people they discriminate against by donating some money to them.[11] Discrimination also develops into a source of oppression, the action of recognizing someone as 'different' so much that they are treated inhumanly and degraded.[12]
This moralized definition of discrimination is distinct from a non-moralized definition—in the former, discrimination is wrong by definition, whereas in the latter, this is not the case.[13]
The United Nations stance on discrimination includes the statement: "Discriminatory behaviors take many forms, but they all involve some form of exclusion or rejection."[14] The United Nations Human Rights Council and other international bodies work towards helping ending discrimination around the world.
Types
[edit]Age
[edit]Ageism or age discrimination is discrimination and stereotyping based on the grounds of someone's age.[15] It is a set of beliefs, norms, and values which used to justify discrimination or subordination based on a person's age.[16] Ageism is most often directed toward elderly people, or adolescents and children.[17][18]
Age discrimination in hiring has been shown to exist in the United States. Joanna Lahey, professor at The Bush School of Government and Public Service at Texas A&M, found that firms are more than 40% more likely to interview a young adult job applicant than an older job applicant.[19] In Europe, Stijn Baert, Jennifer Norga, Yannick Thuy and Marieke Van Hecke, researchers at Ghent University, measured comparable ratios in Belgium. They found that age discrimination is heterogeneous by the activity older candidates undertook during their additional post-educational years. In Belgium, they are only discriminated if they have more years of inactivity or irrelevant employment.[20]
In a survey for the University of Kent, England, 29% of respondents stated that they had suffered from age discrimination. This is a higher proportion than for gender or racial discrimination. Dominic Abrams, social psychology professor at the university, concluded that ageism is the most pervasive form of prejudice experienced in the UK population.[21]
Caste
[edit]According to UNICEF and Human Rights Watch, caste discrimination affects an estimated 250 million people worldwide and is mainly prevalent in parts of Asia (India, Sri Lanka, Bangladesh, Pakistan, Nepal, Japan) and Africa.[22][23] As of 2011[update], there were 200 million Dalits or Scheduled Castes (formerly known as "untouchables") in India.[24]
Citizenship or nationality
[edit]Discrimination on the basis of nationality, citizenship or naturalization is usually included in employment laws.[25] It may vary from laws that regulate hiring and firing based on citizenship, to forced retirement, compensation and pay, etc., based on immigration status. In the GCC states, in the workplace, preferential treatment is given to full citizens, even though many of them lack experience or motivation to do the job. State benefits are also generally available for citizens only.[26] Citizenship discrimination may show as a "level of acceptance" in a team regarding new team members and employees who differ from the citizenship of the majority of team members.[27] Citizenship discrimination can be sometimes connected with racial discrimination[28] although it can be separate.
Class
[edit]Class discrimination, also known as classism, is prejudice or discrimination on the basis of social class. It includes individual attitudes, behaviors, systems of policies and practices that are set up to benefit the upper class at the expense of the lower class.[29]
Social class refers to the grouping of individuals in a hierarchy based on wealth, income, education, occupation, and social network.Disability
[edit]Discrimination against people with disabilities in favor of people who are not is called ableism or disablism. Disability discrimination, which treats non-disabled individuals as the standard of 'normal living', results in public and private places and services, workplaces and educational settings, that are built to serve 'standard' people, which can exclude or hinder those with various disabilities.
Some studies have shown that employment can be beneficial to people with disabilities, helping to sustain their mental health and well-being. Work can fulfil a number of basic needs for an individual such as collective purpose, social contact, status, and activity, therefore reducing social isolation.[30]
Other research shows that employment is not always beneficial, particularly if a disabled persons needs are not considered. A decline in the working age population, particularly in Europe, is resulting in disabled people being seen as more of a valuable resource, within the labour market, for economic reasons.[31]
In the United States, the Americans with Disabilities Act mandates the provision of equality of access to both buildings and services and is paralleled by similar acts in other countries, such as the Equality Act 2010 in the UK.
Excellence
[edit]Language
[edit]
Linguistic discrimination (also called glottophobia, linguicism and languagism) is the unfair treatment of people based upon their use of language and the characteristics of their speech, such as their first language, their accent, the perceived size of their vocabulary (whether or not the speaker uses complex and varied words), their modality, and their syntax.[39] For example, an Occitan speaker in France will probably be treated differently from a French speaker.[40]
Based on a difference in use of language, a person may automatically form judgments about another person's wealth, education, social status, character or other traits, which may lead to discrimination. This has led to public debate surrounding localisation theories, likewise with overall diversity prevalence in numerous nations across the West.
Linguistic discrimination was at first considered an act of racism. In the mid-1980s, linguist Tove Skutnabb-Kangas captured the idea of language-based discrimination as linguicism, which was defined as "ideologies and structures used to legitimize, effectuate, and reproduce unequal divisions of power and resources (both material and non-material) between groups which are defined on the basis of language".[41] Although different names have been given to this form of discrimination, they all hold the same definition. Linguistic discrimination is culturally and socially determined due to preference for one use of language over others.
Scholars have analyzed the role of linguistic imperialism in linguicism, with some asserting that speakers of dominant languages gravitate toward discrimination against speakers of other, less dominant languages, while disadvantaging themselves linguistically by remaining monolingual.[42]
According to Carolyn McKinley, this phenomenon is most present in Africa, where much of the population speaks European languages introduced during the colonial era; African states are also noted as instituting European languages as the main medium of instruction, instead of indigenous languages.[42] UNESCO reports have noted that this has historically benefitted only the African upper class, conversely disadvantaging the majority of Africa's population who hold varying level of fluency in the European languages spoken across the continent.[42]
Scholars have also noted the influence of the linguistic dominance of English on academic disciplines; Anna Wierzbicka, professor of linguistics at the Australian National University, has described disciplines such as the social sciences and humanities as being "locked in a conceptual framework grounded in English", preventing academia as a whole from reaching a "more universal, culture-independent perspective."[43]Name
[edit]Discrimination based on a person's name may also occur, with researchers suggesting that this form of discrimination is present based on a name's meaning, its pronunciation, its uniqueness, its gender affiliation, and its racial affiliation.[44][45][46][47][48] Research has further shown that real world recruiters spend an average of just six seconds reviewing each résumé before making their initial "fit/no fit" screen-out decision and that a person's name is one of the six things they focus on most.[49] France has made it illegal to view a person's name on a résumé when screening for the initial list of most qualified candidates. Great Britain, Germany, Sweden, and the Netherlands have also experimented with name-blind summary processes.[50] Some apparent discrimination may be explained by other factors such as name frequency.[51] The effects of name discrimination based on a name's fluency is subtle, small and subject to significantly changing norms.[52]
Race or ethnicity
[edit]



Racial and ethnic discrimination differentiates individuals on the basis of real and perceived racial and ethnic differences and leads to various forms of the ethnic penalty.[53][54] It can also refer to the belief that groups of humans possess different behavioral traits corresponding to physical appearance and can be divided based on the superiority of one race over another.[55][56][57][58] It may also mean prejudice, discrimination, or antagonism directed against other people because they are of a different race or ethnicity.[56][57]
Modern variants of racism are often based in social perceptions of biological differences between peoples. These views can take the form of social actions, practices or beliefs, or political systems in which different races are ranked as inherently superior or inferior to each other, based on presumed shared inheritable traits, abilities, or qualities.[56][57][59] It has been official government policy in several countries, such as South Africa during the apartheid era. Discriminatory policies towards ethnic minorities include the race-based discrimination against ethnic Indians and Chinese in Malaysia[60] The concept of multiracism has been used to explain the varieties of race discrimination.[61] After the Vietnam War, many Vietnamese refugees moved to Australia and the United States, where they faced discrimination.[62] Westerners might get paid more than other immigrants in GCC states.[63]
Region
[edit]Regional or geographic discrimination is a form of discrimination that is based on the region in which a person lives or the region in which a person was born. It differs from national discrimination because it may not be based on national borders or the country in which the victim lives, instead, it is based on prejudices against a specific region of one or more countries. Examples include discrimination against Chinese people who were born in regions of the countryside that are far away from cities that are located within China, and discrimination against Americans who are from the southern or northern regions of the United States. It is often accompanied by discrimination that is based on accent, dialect, or cultural differences.[64]
Religious beliefs
[edit]| Freedom of religion |
|---|
| Religion portal |

Religious discrimination is valuing or treating people or groups differently because of what they do or do not believe in or because of their feelings towards a given religion. For instance, the Jewish population of Germany, and indeed a large portion of Europe, was subjected to discrimination under Adolf Hitler and his Nazi party between 1933 and 1945. They were forced to live in ghettos, wear an identifying star of David on their clothes, and sent to concentration and death camps in rural Germany and Poland, where they were to be tortured and killed, all because of their Jewish religion. Many laws (most prominently the Nuremberg Laws of 1935) separated those of Jewish faith as supposedly inferior to the Christian population.
Restrictions on the types of occupations that Jewish people could hold were imposed by Christian authorities. Local rulers and church officials closed many professions to religious Jews, pushing them into marginal roles that were considered socially inferior, such as tax and rent collecting and moneylending, occupations that were only tolerated as a "necessary evil".[65] The number of Jews who were permitted to reside in different places was limited; they were concentrated in ghettos and banned from owning land.
In Saudi Arabia, non-Muslims are not allowed to publicly practice their religions and they cannot enter Mecca and Medina.[66][67] Furthermore, private non-Muslim religious gatherings might be raided by the religious police.[67] In Maldives, non-Muslims living and visiting the country are prohibited from openly expressing their religious beliefs, holding public congregations to conduct religious activities, or involving Maldivians in such activities. Those expressing religious beliefs other than Islam may face imprisonment of up to five years or house arrest, fines ranging from 5,000 to 20,000 rufiyaa ($320 to $1,300), and deportation.[68]
In Myanmar, 600,000 Rohingya muslims have been forced to become refugees in Bangladesh due to institutionalised religious discrimination, in law, policy and practice.[69] An example is the government refusing to grant them citizenship, making them stateless without legal documentation. In 2015 Buddhist nationalists protested their right to vote in a constitutional referendum.[70]
In a 1979 consultation on the issue, the United States commission on civil rights defined religious discrimination in relation to the civil rights which are guaranteed by the Fourteenth Amendment. Whereas religious civil liberties, such as the right to hold or not to hold a religious belief, are essential for Freedom of Religion (in the United States as secured by the First Amendment), religious discrimination occurs when someone is denied "equal protection under the law, equality of status under the law, equal treatment in the administration of justice, and equality of opportunity and access to employment, education, housing, public services and facilities, and public accommodation because of their exercise of their right to religious freedom".[71]
Sex, sex characteristics, gender, and gender identity
[edit]Sexism is a form of discrimination based on a person's sex or gender. It has been linked to stereotypes and gender roles,[72][73] and may include the belief that one sex or gender is intrinsically superior to another.[74] Extreme sexism may foster sexual harassment, rape, and other forms of sexual violence.[75] Gender discrimination may encompass sexism and is discrimination toward people based on their gender identity[76] or their gender or sex differences.[77] Gender discrimination is especially defined in terms of workplace inequality.[77] It may arise from social or cultural customs and norms.[78]
Intersex persons experience discrimination due to innate, atypical sex characteristics. Multiple jurisdictions now protect individuals on grounds of intersex status or sex characteristics. South Africa was the first country to explicitly add intersex to legislation, as part of the attribute of 'sex'.[79] Australia was the first country to add an independent attribute, of 'intersex status'.[80][81] Malta was the first to adopt a broader framework of 'sex characteristics', through legislation that also ended modifications to the sex characteristics of minors undertaken for social and cultural reasons.[82][83] Global efforts such as the United Nations Sustainable Development Goal 5 is also aimed at ending all forms of discrimination on the basis of gender and sex.[84]
Sexual orientation
[edit]

One's sexual orientation is a "predilection for homosexuality, heterosexuality, or bisexuality".[85] Like most minority groups, homosexuals and bisexuals are vulnerable to prejudice and discrimination from the majority group. They may experience hatred from others because of their sexuality; a term for such hatred based upon one's sexual orientation is often called homophobia. Many continue to hold negative feelings towards those with non-heterosexual orientations and will discriminate against people who have them or are thought to have them. People of other uncommon sexual orientations also experience discrimination. One study found its sample of heterosexuals to be more prejudiced against asexual people than against homosexual or bisexual people.[86]
Employment discrimination based on sexual orientation varies by country. Revealing a lesbian sexual orientation (by means of mentioning an engagement in a rainbow organisation or by mentioning one's partner name) lowers employment opportunities in Cyprus and Greece but overall, it has no negative effect in Sweden and Belgium.[87][88][89][90] In the latter country, even a positive effect of revealing a lesbian sexual orientation is found for women at their fertile ages.
Besides these academic studies, in 2009, ILGA published a report based on research carried out by Daniel Ottosson at Södertörn University College in Stockholm, Sweden. This research found that of the 80 countries around the world that continue to consider homosexuality illegal, five carry the death penalty for homosexual activity, and two do in some regions of the country.[91] In the report, this is described as "State sponsored homophobia".[92] This happens in Islamic states, or in two cases regions under Islamic authority.[93][94] On February 5, 2005, the IRIN issued a reported titled "Iraq: Male homosexuality still a taboo". The article stated, among other things that honor killings by Iraqis against a gay family member are common and given some legal protection.[95] In August 2009, Human Rights Watch published an extensive report detailing torture of men accused of being gay in Iraq, including the blocking of men's anuses with glue and then giving the men laxatives.[96] Although gay marriage has been legal in South Africa since 2006, same-sex unions are often condemned as "un-African".[97] Research conducted in 2009 shows 86% of black lesbians from the Western Cape live in fear of sexual assault.[98]

A number of countries, especially those in the Western world, have passed measures to alleviate discrimination against sexual minorities, including laws against anti-gay hate crimes and workplace discrimination. Some have also legalized same-sex marriage or civil unions in order to grant same-sex couples the same protections and benefits as opposite-sex couples. In 2011, the United Nations passed its first resolution recognizing LGBT rights.
Reverse discrimination
[edit]
Reverse discrimination is discrimination against members of a dominant or majority group, in favor of members of a minority or historically disadvantaged group.[99]
This discrimination may seek to redress social inequalities under which minority groups have had less access to privileges enjoyed by the majority group. In such cases it is intended to remove discrimination that minority groups may already face. Reverse discrimination can be defined as the unequal treatment of members of the majority groups resulting from preferential policies, as in college admissions or employment, intended to remedy earlier discrimination against minorities.[100]
Conceptualizing affirmative action as reverse discrimination became popular in the early- to mid-1970s, a time period that focused on under-representation and action policies intended to remedy the effects of past discrimination in both government and the business world.[101]

United Nations documents
[edit]Important UN documents addressing discrimination include:
- The Universal Declaration of Human Rights is a declaration adopted by the United Nations General Assembly on December 10, 1948. It states that:" Everyone is entitled to all the rights and freedoms set forth in this Declaration, without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status."[120]
- The International Convention on the Elimination of All Forms of Racial Discrimination (ICERD) is a United Nations convention. The Convention commits its members to the elimination of racial discrimination. The convention was adopted and opened for signature by the United Nations General Assembly on December 21, 1965, and entered into force on January 4, 1969.
- The Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) is an international treaty adopted in 1979 by the United Nations General Assembly. Described as an international bill of rights for women, it came into force on September 3, 1981.
- The Convention on the Rights of Persons with Disabilities is an international human rights instrument treaty of the United Nations. Parties to the convention are required to promote, protect, and ensure the full enjoyment of human rights by persons with disabilities and ensure that they enjoy full equality under the law. The text was adopted by the United Nations General Assembly on December 13, 2006, and opened for signature on March 30, 2007. Following ratification by the 20th party, it came into force on May 3, 2008.
Exemptions
[edit]The Anti-discrimination laws of most countries allow and make exceptions for discrimination based on nationality and immigration status.[121] The International Convention on the Elimination of All Forms of Racial Discrimination (CERD) does not prohibit discrimination by nationality, citizenship or naturalization but forbids discrimination "against any particular nationality".[122]
International cooperation

Theories and philosophy
[edit]Social theories such as egalitarianism assert that social equality should prevail. In some societies, including most developed countries, each individual's civil rights include the right to be free from government sponsored social discrimination.[125] Due to a belief in the capacity to perceive pain or suffering shared by all animals, abolitionist or vegan egalitarianism maintains that the interests of every individual (regardless of their species), warrant equal consideration with the interests of humans, and that not doing so is speciesist.[126]
Philosophers have debated as to how inclusive the definition of discrimination should be. Some philosophers have argued that discrimination should only refer to wrongful or disadvantageous treatment in the context of a socially salient group (such as race, gender, sexuality etc.) within a given context. Under this view, failure to limit the concept of discrimination would lead to it being overinclusive; for example, since most murders occur because of some perceived difference between the perpetrator and the victim, many murders would constitute discrimination if the social salience requirement is not included. Thus this view argues that making the definition of discrimination overinclusive renders it meaningless. Conversely, other philosophers argue that discrimination should simply refer to wrongful disadvantageous treatment regardless of the social salience of the group, arguing that limiting the concept only to socially salient groups is arbitrary, as well as raising issues of determining which groups would count as socially salient. The issue of which groups should count has caused many political and social debates.[13]
Based on realistic-conflict theory[127] and social-identity theory,[128] Rubin and Hewstone[129] have highlighted a distinction among three types of discrimination:
- Realistic competition is driven by self-interest and is aimed at obtaining material resources (e.g., food, territory, customers) for the in-group (e.g., favoring an in-group in order to obtain more resources for its members, including the self).
- Social competition is driven by the need for self-esteem and is aimed at achieving a positive social status for the in-group relative to comparable out-groups (e.g., favoring an in-group in order to make it better than an out-group).
- Consensual discrimination is driven by the need for accuracy[130] and reflects stable and legitimate intergroup status hierarchies (e.g., favoring a high-status in-group because it is high status).
Labeling theory
[edit]
Discrimination, in labeling theory, takes form as mental categorization of minorities and the use of stereotype. This theory describes difference as deviance from the norm, which results in internal devaluation and social stigma[131] that may be seen as discrimination. It is started by describing a "natural" social order. It is distinguished between the fundamental principle of fascism and social democracy.[132][clarification needed] The Nazis in 1930s-era Germany and the pre-1990 Apartheid government of South Africa used racially discriminatory agendas for their political ends. This practice continues with some present day governments.[133]
Game theory
[edit]Economist Yanis Varoufakis (2013) argues that "discrimination based on utterly arbitrary characteristics evolves quickly and systematically in the experimental laboratory", and that neither classical game theory nor neoclassical economics can explain this.[134]
In 2002, Varoufakis and Shaun Hargreaves-Heap ran an experiment where volunteers played a computer-mediated, multiround hawk-dove game. At the start of each session, each participant was assigned a color at random, either red or blue. At each round, each player learned the color assigned to his or her opponent, but nothing else about the opponent. Hargreaves-Heap and Varoufakis found that the players' behavior within a session frequently developed a discriminatory convention, giving a Nash equilibrium where players of one color (the "advantaged" color) consistently played the aggressive "hawk" strategy against players of the other, "disadvantaged" color, who played the acquiescent "dove" strategy against the advantaged color. Players of both colors used a mixed strategy when playing against players assigned the same color as their own. The experimenters then added a cooperation option to the game, and found that disadvantaged players usually cooperated with each other, while advantaged players usually did not. They state that while the equilibria reached in the original hawk-dove game are predicted by evolutionary game theory, game theory does not explain the emergence of cooperation in the disadvantaged group. Citing earlier psychological work of Matthew Rabin, they hypothesize that a norm of differing entitlements emerges across the two groups, and that this norm could define a "fairness" equilibrium within the disadvantaged group.[135]
Effects on health
[edit]The psychological impact of discrimination on health refers to the cognitive pathways through which discrimination impacts mental and physical health in marginalized, and lower-status groups (e.g. racial and sexual minorities).[136] Research on the relationship between discrimination and health grew in the 1990s, when researchers proposed that persisting racial/ethnic disparities in health outcomes could be explained by racial or ethnic differences in experiences with discrimination.[137] While much research focuses on the interactions between interpersonal discrimination and health, researchers studying discrimination and health in the United States have proposed that institutional discrimination and cultural racism also create conditions that contribute to persisting racial and economic health disparities.[138][139]
A stress and coping framework[140] is applied to investigate how discrimination influences health outcomes in racial, gender, and sexual minorities, as well as on immigrant and indigenous populations.[141][142] The research indicates that experiences of discrimination are associated with worse physical and mental health conditions and lead to increased participation in unhealthy behaviors.[143] Evidence of the inverse link between discrimination and health has been observed consistently across multiple population groups and various cultural and national contexts.[144]Analysis of data from the UK Household Longitudinal Study has shown a link between disability discrimination and wellbeing. 13.4% of disabled people have felt discriminated against. Larger European studies have found disability discrimination to be very common. Disability discrimination was associated with lower wellbeing, for example depression, self rated health, psychological distress and life satisfaction.[145]

[A]s a reasonable first approximation, we can say that discrimination consists of acts, practices, or policies that impose a relative disadvantage on persons based on their membership in a salient social group. [...] [W]e can refine the first-approximation account of discrimination and say that the moralized concept of discrimination is properly applied to acts, practices or policies that meet two conditions: a) they wrongfully impose a relative disadvantage or deprivation on persons based on their membership in some salient social group, and b) the wrongfulness rests (in part) on the fact that the imposition of the disadvantage is on account of the group membership of the victims.

GENDER OR SEX DISCRIMINATION: This term refers to the types of gender bias that have a negative impact. The term has legal, as well as theoretical and psychological, definitions. Psychological consequences can be more readily inferred from the latter, but both definitions are of significance. Theoretically, gender discrimination has been described as (1) the unequal rewards that men and women receive in the workplace or academic environment because of their gender or sex difference (DiThomaso, 1989); (2) a process occurring in work or educational settings in which an individual is overtly or covertly limited access to an opportunity or a resource because of a sex or is given the opportunity or the resource reluctantly and may face harassment for picking it (Roeske & Pleck, 1983); or (3) both.

If a being suffers, there can be no moral justification for refusing to take that suffering into consideration. ... This is why the limit of sentience ... is the only defensible boundary of concern for the interests of others. ... Similarly those I would call 'speciesists' give greater weight to their own species when there is a clash between their interests and the interests of those of other species.

View on GrokipediaConceptual Foundations
Etymology and Linguistic Origins
The English word discrimination entered usage in the 1640s, borrowed from Late Latin discriminationem (nominative discriminatio), the action of dividing or separating.[1] Its root lies in the Latin verb discriminare, meaning "to distinguish between" or "to divide," derived from discrimen ("division, distinction, or judgment"), which stems from discernere ("to separate" or "to perceive differences").[10] The prefix dis- ("apart" or "asunder") combines with cernere ("to sift, separate, or decide"), linking etymologically to concepts of sifting evidence or rendering verdicts, as in ancient Roman legal or perceptual contexts. Initially, discrimination connoted a neutral or positive faculty of discernment, referring to the act of making perceptive distinctions or exercising refined judgment, as evidenced in early 17th-century English texts emphasizing cognitive acuity.[2] This sense aligned with classical Latin usage, where related terms implied analytical separation without moral valence.[11] By the 19th century, particularly in American English, the term shifted toward a negative implication of unfair or prejudicial differentiation, first documented in 1866 amid debates over the Civil Rights Bill targeting treatment based on race or prior servitude.[1][12] Cognates appear in Romance languages, such as French discrimination and Italian discriminazione, retaining the Latin core while mirroring English's semantic evolution from neutral distinction to bias-laden exclusion in modern legal and social discourse.[1] This linguistic trajectory reflects broader cultural changes, where the capacity for rational differentiation—once prized—became associated with systemic inequities rather than inherent perceptual skill.[2]Core Definitions and Distinctions
Discrimination is fundamentally the practice of making distinctions in treatment, opportunities, or outcomes between individuals or groups based on characteristics such as race, sex, religion, or national origin, rather than solely on individual qualifications or actions.[13] In economic terms, as articulated by Gary Becker in his 1957 analysis, it arises when economic agents—such as employers or consumers—bear a cost by avoiding transactions with certain groups due to preferences unrelated to productivity, leading to wage gaps or market inefficiencies for equally capable individuals.[14] [15] This definition emphasizes observable behaviors and outcomes over mere attitudes, distinguishing it from purely internal states. A key distinction exists between discrimination and prejudice: prejudice involves preconceived, often emotional attitudes or hostility toward a group, independent of evidence, while discrimination manifests as tangible actions or policies that disadvantage the group.[8] [16] Similarly, bias refers to cognitive or implicit inclinations that skew judgments, which may inform but do not equate to discriminatory conduct unless enacted.[16] Stereotypes, as cognitive shortcuts generalizing group traits, can underpin prejudice but become discriminatory only when they drive differential treatment, such as exclusion from opportunities.[8] Discrimination further divides into rational and irrational forms. Rational discrimination employs accurate statistical generalizations about group differences in relevant traits—such as higher group-level variance in reliability or performance—when individual assessments are costly or infeasible, thereby minimizing errors in decisions like hiring or lending.[17] [18] Irrational discrimination, conversely, stems from unfounded animus or errors, imposing unnecessary costs without predictive value, as critiqued in competitive market models where such preferences self-correct via losses to discriminators.[14] [19] Legally, in the United States, discrimination is codified under Title VII of the Civil Rights Act of 1964 as adverse employment actions based on protected categories including race, color, religion, sex, or national origin, prohibiting both intentional disparate treatment and practices with unjustified disparate impacts.[20] [21] This framework prioritizes equality of outcome proxies but overlooks rational bases rooted in empirical group variances, potentially conflating statistical realities with prohibited bias.[17]Rational Discrimination in Theory and Practice
Statistical discrimination, a foundational concept in economic theory, posits that decision-makers rationally infer individual traits from group averages when individual information is imperfect or costly, leading to differential treatment based on probabilistic assessments rather than animus. This model, distinct from taste-based discrimination where agents bear a psychic cost for associating with certain groups, was formalized by Edmund Phelps in his 1972 paper, which demonstrated how employers facing noisy productivity signals may offer lower wages to members of groups with lower average qualifications, perpetuating disparities even among equally productive individuals.[22] Kenneth Arrow extended this in 1973 by incorporating signaling and coordination, showing that in competitive markets, firms may underinvest in training for discriminated groups due to anticipated higher quit rates inferred from group statistics, resulting in equilibrium inefficiencies.[23] In labor markets, statistical discrimination manifests when hiring or promotion decisions rely on group-level data amid asymmetric information; for instance, empirical analyses indicate that resumes from groups with historically higher variance in performance receive lower callback rates unless augmented by strong individual signals like elite education, as firms weigh expected productivity against screening costs.[4] A classic real-world example involves taxicab drivers selectively refusing fares from young black males in high-crime urban areas, justified by disproportionate robbery statistics—data from 1990s studies show black males comprised 50-70% of assailants against cabbies despite being 12% of the population—yielding rational risk aversion that maximizes driver safety and earnings, though it imposes externalities on innocent individuals.[17] Insurance pricing exemplifies rational discrimination through actuarial practices, where premiums reflect empirical group risks to ensure solvency and fairness; for example, young male drivers face 20-50% higher auto rates than females of similar age due to crash data showing males under 25 account for 27% of fatal accidents despite being 12% of licensed drivers, a classification upheld as non-discriminatory when predictive of claims experience.[24] Similarly, life insurers historically charged higher rates to groups with elevated mortality, such as smokers or certain occupations, based on longitudinal data; while race-based differentials were curtailed by regulation post-1970s, proxies like geography persist where they correlate with verifiable risks like health outcomes or property crime.[25] These applications underscore that suppressing statistical inferences can distort markets, increasing costs for low-risk members of high-risk groups via adverse selection, as evidenced by community-rated health plans experiencing 10-15% premium hikes from unpriced risks.[26]Biological and Evolutionary Bases
Evolutionary Psychology of Ingroup Preferences
Ingroup favoritism refers to the preferential treatment, cooperation, and resource allocation toward members of one's own social group compared to outgroup members, a pattern observed across human societies and linked to evolutionary adaptations for survival in group-based ancestral environments. This preference likely arose because early humans lived in small, kin-related bands where intra-group cooperation enhanced protection against predators, resource acquisition, and reproduction, while inter-group competition over scarce resources posed recurrent threats; mathematical models demonstrate that such favoritism can evolve stably when groups engage in costly conflicts, as individuals who prioritize ingroup members gain fitness advantages through mutual aid and collective defense.[27][28] Theoretical frameworks in evolutionary psychology posit that ingroup preferences stem from extended kin selection and reciprocal altruism, extended beyond genetic relatives to coalition members sharing phenotypic cues like language, appearance, or norms, which signal reliability in repeated interactions; parochial altruism further explains this as a strategy pairing ingroup generosity with outgroup hostility, promoting group-level success in zero-sum intergroup contests, as simulated in agent-based models where moderate favoritism outperforms pure selfishness or universal cooperation. Empirical support comes from minimal group paradigms, where arbitrary assignments (e.g., based on abstract preferences) elicit favoritism in resource allocation tasks, with bias intensifying over repeated dilemmas as participants learn group norms, indicating an innate readiness rather than learned ideology.[29][30] Neuroscience evidence reinforces an evolved basis, with functional MRI studies showing heightened amygdala activation and reduced empathy-related activity (e.g., in the anterior insula) when processing outgroup faces or pain, contrasted with stronger mirror neuron responses for ingroup suffering, suggesting automatic categorization mechanisms honed by ancestral threats from unfamiliar outsiders. Cross-cultural experiments across 20 countries reveal ingroup favoritism in economic games as a near-universal default, though modulated by cultural factors like individualism, with stronger bias in high-discrimination societies; this variation aligns with evolutionary predictions that environmental pressures, such as pathogen prevalence or resource scarcity, amplify the adaptive value of tribal loyalties.[31][32] Primate analogs, including chimpanzee coalitionary killing of outgroup rivals, provide comparative data supporting homology, as human hyper-coalitional psychology likely amplified these traits for large-scale warfare and alliance-building during the Pleistocene.[33]Cognitive and Instinctual Mechanisms
Cognitive categorization, a fundamental process in human perception, groups individuals into social categories based on observable traits such as race, ethnicity, or sex, enabling efficient information processing but often resulting in stereotyping and biased judgments. Experimental studies demonstrate that such categorization triggers automatic associations, where outgroup members are more readily linked to negative stereotypes due to salience of dissimilar features in memory recall tasks. For instance, in benchmark experiments, participants exhibited poorer memory for positive traits of racial outgroup members compared to ingroup counterparts, suggesting a cognitive bias that favors ingroup-positive information and contributes to discriminatory evaluations independent of explicit prejudice.[34][35] Implicit biases, operationalized through tools like the Implicit Association Test (IAT), reflect unconscious evaluative preferences that influence discriminatory behavior, such as hiring decisions or interpersonal interactions, though meta-analyses indicate modest correlations with actual actions, raising questions about their causal potency beyond situational factors. These biases arise from associative learning reinforced by cultural exposure and personal experiences, but they persist even when explicit attitudes are egalitarian, as shown in neuroimaging where automatic racial evaluations activate brain regions linked to emotional processing before conscious deliberation. Peer-reviewed evidence attributes this to heuristic shortcuts in decision-making, where statistical patterns from past encounters (e.g., crime rates by group) unconsciously inform judgments, aligning with rational discrimination models rather than irrational animus.[36][37] Instinctual mechanisms root in evolutionary adaptations for survival, where ingroup favoritism and outgroup vigilance minimized risks from coalitional threats or disease transmission in ancestral environments. Cross-cultural data and primate analogs reveal universal tendencies toward nepotism and xenophobia, with prejudice emerging as an extension of kin selection principles, favoring resource allocation to genetic relatives and familiar allies over strangers. Empirical support comes from studies showing heightened physiological responses (e.g., cortisol spikes) to outgroup symbols, interpreted as adaptive caution rather than maladaptive pathology, though modern low-threat contexts amplify these instincts into exaggerated biases.[38][39] At the neural level, the amygdala exhibits selective activation to outgroup faces, signaling potential danger and modulating prefrontal cortex activity to bias threat detection, as evidenced by fMRI meta-analyses of intergroup encounters. This subcortical response precedes cortical evaluation, underscoring an instinctual primacy that overrides deliberative reasoning in ambiguous situations, with genetic underpinnings suggested by heritability estimates of prejudice traits around 30-50% in twin studies. Such mechanisms, while fostering discrimination, likely conferred fitness advantages by promoting cohesive groups and avoiding exploitative outsiders, per evolutionary models.[40][41][42]Historical Evolution of the Concept
Pre-Modern and Traditional Societies
In pre-modern societies, discrimination was typically embedded in social structures as a mechanism for maintaining order, allocating resources, and ensuring group survival, often favoring kin, tribe, or status hierarchies over universal equality. Anthropological evidence from traditional small-scale societies indicates that ingroup favoritism and outgroup derogation were prevalent, with individuals showing bias toward their own group in resource distribution and conflict resolution, as observed in multiplayer economic games among naturally occurring groups where participants discriminated against outgroup members by allocating fewer resources to them.[43] This pattern aligns with evolutionary pressures in tribal contexts, where exclusion of outsiders reduced risks of exploitation or conflict, though it did not always manifest as outright hostility but as preferential treatment for familiars.[44] Early codified laws exemplify class-based discrimination. The Code of Hammurabi, promulgated around 1750 BCE in Babylon, differentiated penalties by social status: for instance, injuring a free man's eye warranted reciprocal injury to the perpetrator, while injuring a commoner's eye incurred only a monetary fine of half a mina of silver, and a slave's injury merited even lesser compensation equivalent to the slave's market value.[45] Similarly, in ancient Rome from the Republic through the Empire (c. 509 BCE–476 CE), slavery institutionalized discrimination against foreigners, who comprised the majority of the estimated 10–20% of Italy's population that were slaves, often captured in wars and denied citizenship rights, with treatment varying by owner but legally permitting corporal punishment and sale as property.[46] Roman law further distinguished citizens from peregrini (foreigners) and slaves, limiting the latter's legal recourse and barring them from intermarriage or property ownership without manumission.[47] In South Asia, the varna system outlined in Vedic texts like the Rigveda (c. 1500–1200 BCE) stratified society into priests, warriors, commoners, and servants, evolving into rigid jati castes by the early centuries CE, where lower groups faced hereditary occupational restrictions and ritual pollution taboos, as seen in the exclusion of Dalits from temples and wells, enforcing economic and social segregation.[48] Medieval Europe (c. 500–1500 CE) perpetuated status discrimination through serfdom, binding peasants to manors and lords from the 9th century onward, restricting mobility, marriage, and inheritance without seigneurial consent, while religious discrimination targeted Jews and Muslims via laws like the Fourth Lateran Council's (1215) mandates for distinctive clothing and ghettoization, justified by theological views of non-Christians as perpetual outsiders.[49][50] These practices were generally viewed not as moral failings but as pragmatic enforcements of hierarchy, with deviations risking social instability, though manumission or conversion occasionally allowed limited upward mobility.[51]19th-20th Century Developments
In the 19th century, the term "discrimination," derived from the Latin discrimen meaning division or distinction, increasingly connoted unjust treatment based on perceived group differences, particularly in the post-slavery United States.[12] Following the Civil War and Reconstruction era (1865–1877), Southern states enacted Black Codes and later Jim Crow laws to enforce racial segregation and restrict African American rights, formalizing discrimination in voting, education, and public accommodations.[52] These measures, upheld by the U.S. Supreme Court in Plessy v. Ferguson (1896) under the "separate but equal" doctrine, institutionalized differential treatment justified as preserving social order amid racial tensions.[53] Scientific racism emerged concurrently, with European and American intellectuals applying pseudoscientific methods like craniometry and anthropometry to argue for innate racial hierarchies that rationalized discriminatory policies.[54] Works such as Joseph Arthur de Gobineau's Essay on the Inequality of the Human Races (1853–1855) posited Aryan superiority, influencing immigration restrictions and colonial practices.[55] In the United States, northern Black communities faced ongoing housing and employment barriers, prompting organized resistance through mutual aid societies and legal challenges.[56] The early 20th century saw the concept of discrimination expand to include institutional and psychological dimensions, with sociologists and psychologists beginning to study prejudice as a precursor to discriminatory acts.[57] Eugenics policies, peaking in the 1920s, led to forced sterilizations of over 60,000 individuals deemed "unfit" in the U.S., often targeting racial minorities and the poor, under the guise of genetic improvement.[54] The 1924 Immigration Act quota system explicitly favored Northern Europeans, reflecting statistical discrimination based on perceived cultural and racial compatibility.[58] World War I-era restrictions on German Americans and rising anti-Semitism, exemplified by the Dreyfus Affair's lingering impact in Europe, highlighted ethnic discrimination amid nationalism.[55] By mid-century, the Holocaust (1941–1945) exposed the catastrophic potential of state-enforced racial discrimination, discrediting overt scientific racism and prompting international repudiations like UNESCO's 1950 statement on race, which rejected biological determinism of prejudice.[59] In the U.S., persistent Jim Crow segregation persisted until challenged by wartime labor demands and the 1948 desegregation of the armed forces via Executive Order 9981, marking a shift toward viewing discrimination as a barrier to merit-based opportunity.[60] These developments reframed discrimination from an accepted social mechanism to a target for reform, though empirical group differences continued to underpin rational distinctions in policy debates.[61]Post-1960s Legal and Cultural Shifts
The Civil Rights Act of 1964 marked a foundational legal shift in the United States, prohibiting discrimination in public accommodations, employment, and federally funded programs based on race, color, religion, sex, or national origin, with Title VII establishing the Equal Employment Opportunity Commission (EEOC) to enforce workplace protections.[62] This was followed by the Voting Rights Act of 1965, which targeted barriers to Black voter registration and participation in Southern states through federal oversight of election practices.[62] The Fair Housing Act of 1968 extended prohibitions to real estate transactions, addressing residential segregation that had persisted despite earlier reforms.[63] Subsequent U.S. legislation broadened these protections, including the Equal Pay Act of 1963 mandating equal remuneration for equal work regardless of sex, and the Americans with Disabilities Act of 1990 barring discrimination against qualified individuals with disabilities in employment, public services, and accommodations.[62] Affirmative action policies, initially executive orders under Presidents Kennedy and Johnson, aimed to remedy past discrimination through preferential hiring and admissions, though their implementation via disparate impact standards—established in Griggs v. Duke Power Co. (1971)—shifted focus from intent to outcomes, prompting debates over quotas and reverse discrimination.[64] Enforcement data from the EEOC show a rise in discrimination claims from the 1970s onward, with racial and sex-based filings increasing amid heightened awareness and legal access.[3] In Europe, U.S. models influenced post-1960s laws, such as the United Kingdom's Race Relations Act 1976, which outlawed discrimination in employment, housing, and services on grounds of race or ethnicity, and the Sex Discrimination Act 1975 addressing gender-based inequities.[65] The European Union formalized these through directives like the 2000 Racial Equality Directive, requiring member states to combat discrimination in employment and training based on racial or ethnic origin.[66] These frameworks emphasized indirect discrimination, where neutral policies with disproportionate effects on protected groups could be challenged, paralleling U.S. developments but often with stronger emphasis on positive duties for equality.[67] Culturally, the 1970s saw normalization of anti-discrimination norms through social movements, including feminist advocacy for workplace equity and early gay rights efforts challenging sodomy laws and employment biases, fostering broader societal intolerance for overt prejudice.[68] Surveys indicate a marked decline in explicit racist and sexist attitudes from the 1960s to the 1990s, with opposition to interracial marriage dropping from 72% in 1968 to 4% by 2016, reflecting internalized equality principles amid media and educational campaigns.[69][70] Empirically, overt discrimination diminished post-1960s, with Black employment rates and wages converging toward White levels in certain sectors due to enforcement, though meta-analyses of audit studies reveal persistent racial gaps in hiring callbacks unchanged since the 1990s.[71][72] Unintended effects include heightened litigation burdens on employers under disparate impact rules, potentially discouraging hiring in high-risk demographics, and critiques that affirmative action exacerbated mismatches in education without proportional gains in outcomes.[64][73] Recent data show a uptick in social dominance orientation—a proxy for tolerance of inequality—post-2012, suggesting cultural backsliding amid polarization.[70]Categories of Discrimination
Discrimination by Immutable Traits
Discrimination by immutable traits encompasses adverse treatment in employment, housing, or services based on inherent characteristics such as race, ethnicity, sex, age, or disability, which individuals cannot alter without extraordinary effort.[74] These traits form the core of protections under laws like Title VII of the Civil Rights Act of 1964 (race, sex, national origin), the Age Discrimination in Employment Act of 1967 (age), and the Americans with Disabilities Act of 1990 (disability).[20] Empirical assessments, including audit and correspondence studies, reveal varying degrees of such discrimination, though methodological critiques highlight limitations like assuming identical qualifications across applicants and overlooking statistical or rational bases for decisions.[72] Racial and ethnic discrimination persists in hiring, as evidenced by meta-analyses of field experiments showing African Americans receive 36% fewer callbacks than equally qualified white applicants, with no decline over decades from the 1990s to 2010s.[72] Similar patterns hold for Latinos, though effects are smaller at 24% fewer callbacks, concentrated in contexts like customer-facing roles where statistical differences in group behaviors may contribute.[75] In the U.S., the Equal Employment Opportunity Commission (EEOC) received over 88,000 discrimination charges in fiscal year 2024, with race comprising a leading basis alongside retaliation, though charges do not confirm proven discrimination.[76] Critiques note that name-based signals in resumes may proxy for cultural or skill differences, not pure prejudice, and real-world hiring involves multifaceted evaluations beyond controlled experiments.[77] Sex-based discrimination in hiring shows weaker evidence in audit studies; a cross-national analysis found no systematic disadvantage for women across occupations in Europe and the U.S.[78] U.S.-specific meta-analyses of correspondence tests over three decades indicate modest gaps favoring men in male-dominated fields but reversals in female-dominated ones, with overall effects smaller than for race.[79] Disparities like the gender wage gap—13.7% unadjusted in 2023—largely dissipate after controlling for occupation, hours, and experience, suggesting choices driven by biological preferences for work-life balance over pure bias. EEOC data reflect fewer sex charges relative to race, underscoring that overt discrimination has declined post-1964, though subtle biases in promotions persist in some sectors.[80] Age discrimination targets older workers (typically over 40), with field experiments demonstrating 20-40% fewer callbacks for applicants aged 64 versus 32 with identical resumes.[81] A 2023 meta-analysis confirmed ageism in hiring across Western labor markets, often rationalized by stereotypes of lower adaptability, though productivity data show older workers' experience offsets such concerns in many roles.[82] U.S. employment rates for those 55+ lag younger cohorts, partly due to bias, but also preferences for phased retirement; ADEA filings rose in recent years amid tech sector shifts favoring youth.[83] Disability discrimination affects hiring and accommodations, with post-ADA surveys indicating 10% of working disabled adults faced workplace bias within five years of the 1990 law.[84] Employment rates for disabled persons stood at 22.7% in 2024 versus 65.5% for non-disabled, though causation includes health limitations beyond prejudice; EEOC suits on disability comprised 34% of 2023 filings.[85][86] Audit studies reveal hesitation in callbacks for disclosed disabilities, but reasonable accommodations often mitigate costs, challenging claims of undue burden.[75]Discrimination by Behavioral or Achieved Traits
Discrimination by behavioral or achieved traits involves differential treatment based on characteristics influenced by personal choices, efforts, or habits, such as criminal convictions, smoking, obesity, educational qualifications, or work ethic. These traits are distinguishable from immutable ones because individuals can, in principle, modify them through behavior change or achievement, often making associated discrimination rational when the traits correlate with verifiable risks, costs, or productivity differences. Empirical evidence supports that such discrimination frequently serves economic efficiency rather than animus, as decision-makers like employers weigh observable signals of future performance.[87] In employment contexts, screening for criminal history exemplifies rational discrimination against behavioral traits. Ex-offenders face widespread reluctance in hiring due to high recidivism rates, which signal potential for repeated misconduct. A Bureau of Justice Statistics study tracking over 400,000 state prisoners released in 2005 found that 68% were rearrested within three years, 83% within nine years, encompassing new crimes ranging from property offenses to violence.[88] This pattern justifies employer caution, as hiring individuals with such histories elevates risks of workplace theft, absenteeism, or legal liabilities, with economic models framing it as statistical discrimination to avoid imperfect information costs.[89] Policies like "ban the box" laws, which delay criminal history inquiries, have yielded mixed results; while intended to reduce barriers, they can obscure risks, potentially increasing employer hesitancy or unintended hires of higher-risk candidates.[90] Health-related behaviors, such as smoking and obesity, prompt similar discrimination, often tied to quantifiable employer burdens. Smokers incur excess costs averaging $5,816 annually per employee, including $3,000 in elevated health claims and $2,000 in productivity losses from illness and breaks.[91] Overweight workers face analogous treatment, with obesity-linked conditions driving higher insurance premiums and absenteeism; for instance, severe obesity correlates with 1.7 times greater healthcare expenditures than normal weight peers.[92] While some states, like Michigan, prohibit weight-based discrimination by classifying severe obesity as a disability, federal law permits lifestyle-based exclusions in at-will employment unless tied to protected categories, reflecting recognition that modifiable habits impose external costs.[93] Critics argue this constitutes "healthism," but causal analysis prioritizes evidence of avoidable expenses over equity claims, as incentives for behavior change—such as surcharges—have reduced smoking rates without broad productivity harm.[94] Educational attainment and skills, as achieved traits, underpin routine discrimination in labor markets, where lower qualifications predict reduced output. Employers rationally favor candidates with higher education or demonstrated competencies, as meta-analyses show college degrees correlate with 20-30% wage premiums due to enhanced productivity and trainability.[95] Termed "educationism" in some analyses, this preference disadvantages those with minimal schooling, who comprise about 10% of U.S. adults without high school diplomas and face unemployment rates double the national average.[96] Such practices align with first-principles efficiency: firms minimize hiring errors by proxying skills via credentials, avoiding the costs of underperformance. Legal systems uphold this via at-will doctrines, absent quotas, though affirmative action in some sectors discriminates against high-achievers to favor less-qualified candidates based on group traits.[97] In housing and lending, behavioral traits like poor credit history—often resulting from financial mismanagement—lead to higher interest rates or denials, reflecting actuarial risk rather than bias. Subprime borrowers default at rates 3-5 times higher than prime, justifying premiums that average 2-4 percentage points.[98] This extends to social domains, where associations avoid unreliable individuals, as game-theoretic models demonstrate that punishing defection (e.g., via exclusion) sustains cooperation. Overall, while labeled discriminatory, treatment based on achieved traits incentivizes improvement and resource allocation, with empirical critiques of overprotection showing unintended rises in societal costs, such as recidivism spikes post-decriminalization efforts.[99]Claims of Systemic or Institutional Discrimination
Claims of systemic or institutional discrimination assert that discriminatory outcomes arise not merely from individual prejudices but from entrenched structures, policies, and norms within organizations and societies that perpetuate unequal treatment of groups defined by race, ethnicity, gender, or other traits. These claims gained prominence in the late 20th century, particularly following the U.S. Civil Rights Act of 1964, with advocates pointing to disparate outcomes—such as racial gaps in employment, incarceration, and education—as prima facie evidence of bias embedded in neutral-seeming rules. For instance, the disparate impact doctrine, established in Griggs v. Duke Power Co. (1971), holds employers liable for policies yielding statistically unequal results across groups unless proven job-related, even absent intent; proponents argue this uncovers covert institutional racism, as seen in challenges to standardized testing or criminal background checks disproportionately affecting minorities.[100][101] Empirical support for such claims draws heavily from audit and correspondence studies simulating hiring processes, where meta-analyses of U.S. field experiments from the 1990s to 2020s reveal persistent racial gaps: Black applicants receive approximately 36% fewer callbacks than equally qualified White applicants, with no decline over time despite anti-discrimination laws.[102][103] Similar patterns appear in housing and lending, where minority applicants face higher denial rates in controlled tests. However, these studies measure potential interpersonal biases in initial screening rather than systemic policy failures, and their effect sizes—often equivalent to the impact of a single educational credential—pale against confounders like skill signaling or applicant quality variations. Critics note that academic and advocacy sources promoting these as evidence of institutional racism frequently underemphasize alternative explanations, such as statistical discrimination where employers rationally weigh group-level risk signals derived from aggregate behaviors.[75] In criminal justice, systemic claims highlight disproportionate Black incarceration rates (e.g., Blacks comprising 13% of the population but 33% of prisoners as of 2023), attributing them to biased policing and sentencing. Yet rigorous analyses controlling for offense types and local crime data find arrest disparities align closely with victim-reported perpetrator demographics, indicating higher offending rates rather than institutional animus; for example, FBI Uniform Crime Reports and National Crime Victimization Surveys from 2019-2022 show Blacks overrepresented in homicides by factors of 7-8 relative to population share.[104] The disparate impact approach in sentencing guidelines has faced rebuke for conflating outcomes with causation, ignoring that neutral policies like "three-strikes" laws address real recidivism patterns without embedding prejudice. Broader critiques argue these claims systematically downplay cultural and behavioral factors—such as single-parent household rates correlating 0.7-0.8 with poverty and crime persistence—favoring narratives of oppression that overlook post-1960s policy shifts reducing overt barriers.[105] In education, achievement gaps (e.g., 2022 NAEP scores showing Black students 30-40 points below Whites in math) are often framed as institutional failure, but longitudinal data link them more robustly to family socioeconomic controls than school discrimination.[106] Institutional discrimination claims extend to gender, positing "glass ceilings" in leadership despite women's 57% share of college degrees as of 2023; however, controlled studies attribute executive underrepresentation to choices like career interruptions for childbearing, with adjusted pay gaps shrinking to 3-7% versus the raw 18-20%.[79] Affirmative action policies, defended as remedies for systemic legacies, have conversely been litigated as institutional discrimination against Asians and Whites in admissions, as in Students for Fair Admissions v. Harvard (2023), where race-neutral alternatives yielded similar diversity without quotas. Overall, while isolated institutional biases persist, exaggerated systemic narratives risk policy distortions, such as DEI mandates prioritizing group outcomes over individual merit, as evidenced by corporate backlash and legal reversals since 2023.[107]Theoretical Explanations
Economic Models of Statistical Discrimination
Statistical discrimination in economic theory refers to situations where agents, such as employers, make decisions based on probabilistic inferences about individuals' unobservable traits using observable group averages, rather than prejudice or taste.[108] This approach contrasts with Gary Becker's 1957 taste-based model, where discrimination stems from a disutility from associating with certain groups, leading to inefficient outcomes in competitive markets.[109] In statistical models, discrimination emerges rationally from information constraints, where firms cannot costlessly observe individual productivity and thus condition wages or hiring on group statistics. Edmund Phelps introduced a foundational model in 1972, positing that employers set wages equal to the expected marginal productivity of workers from a given group, inferred from group mean productivity due to noisy individual signals.[110] If two groups differ in average productivity—say, Group A higher than Group B—workers from Group B receive lower wages on average, even if their individual productivity matches Group A's mean, because the wage formula applies the group expectation uniformly.[111] This creates a feedback loop: lower wages for Group B reduce incentives for its members to invest in human capital, widening the productivity gap and perpetuating the disparity in equilibrium.[112] Kenneth Arrow's 1973 model extends this by focusing on hiring decisions under uncertainty, where firms set productivity thresholds for employment based on group-specific expected values from imperfect tests.[113] If a group's mean ability is lower or its signal variance higher, fewer members meet the threshold relative to a higher-mean group, resulting in underrepresentation despite equal individual distributions.[114] Arrow emphasized coordination failures: all firms using the same group priors leads to self-reinforcing underinvestment in the disadvantaged group, as individuals anticipate discrimination and reduce effort in skill acquisition.[111] Dennis Aigner and Glen Cain's 1977 survey formalized screening variants, where firms may invest differently in observing workers from groups with varying signal reliability—e.g., exerting more effort to screen a high-variance group but still basing decisions on Bayesian updates from group priors. In competitive equilibrium, such models predict wage gaps mirroring productivity differences without animus, but they can amplify initial disparities if groups face asymmetric information costs.[115] Empirical tests, such as audit studies, have sought to distinguish statistical from taste-based discrimination by examining responses to variance in applicant signals, though identification remains challenging due to unobserved heterogeneity.[116] Extensions, like dynamic models, show belief flipping where temporary shocks can reverse group equilibria, highlighting the fragility of statistical discrimination under changing priors.[112]Sociological and Cultural Critiques
Sociological theories of discrimination, such as conflict theory, often portray it as a mechanism by which dominant groups maintain power through systemic prejudice and resource allocation, leading to persistent group disparities.[117] Critics contend that this framework overlooks empirical evidence of cultural and behavioral differences that independently drive outcomes, conflating correlation with causation and assuming discrimination where rational statistical assessments or self-selection prevail.[118] Economist Thomas Sowell, in his analysis of group outcomes across history and nations, argues that disparities require testing multiple causal prerequisites beyond discrimination, including geography, culture, and individual behaviors; for instance, immigrant groups like the Irish and Italians in the 19th-century United States faced severe prejudice yet achieved socioeconomic mobility through cultural adaptations emphasizing delayed gratification and education, without legal interventions.[119][120] Cultural factors, such as family structure and values toward work and learning, provide stronger explanatory power for disparities than prejudice alone, according to empirical cross-group comparisons. Sowell documents how Asian Americans, despite historical discrimination like the Chinese Exclusion Act of 1882, exhibit higher educational attainment and income levels attributable to cultural norms prioritizing academic effort and intact families, with two-parent households correlating with reduced poverty rates across racial groups—72% of black children born in 1965 to married parents saw 80% remain low-income as adults if families stayed intact, versus stark declines otherwise.[121] These patterns hold internationally; Nigerian immigrants in the U.S. outperform native blacks economically due to selective migration and retained cultural emphases on achievement, not diminished bias.[120] Sociological models attributing gaps primarily to external discrimination are critiqued for neglecting such data, often emerging from academic environments with ideological homogeneity that resists cultural explanations to preserve narratives of victimhood.[122] From a cultural realist perspective, in-group preferences and aversion to out-group risks reflect evolved adaptations rather than pathological prejudice, challenging purely social constructionist views. Evolutionary psychology posits that intergroup bias, including discrimination against perceived threats, arises from ancestral environments favoring kin and coalitional loyalty for survival, as evidenced by cross-cultural studies showing universal male warrior tendencies toward out-group males in competitive scenarios.[42][33] Culturally transmitted norms amplify this; groups with higher rates of behaviors like violence—linked to cultural tolerances rather than innate traits—face legitimate employer wariness, constituting rational discrimination rather than irrational bias, with labor market audits confirming statistical rather than taste-based motives in hiring disparities.[123] Critics of mainstream sociology argue this underemphasis on causal cultural realism perpetuates ineffective policies, as interventions ignoring behavioral incentives fail to close gaps, per longitudinal data on welfare reforms boosting employment via work requirements.[124]Behavioral and Cultural Factor Analyses
Behavioral and cultural factor analyses posit that disparities in socioeconomic outcomes between groups often originate from differences in behaviors, values, and norms transmitted across generations, rather than primarily from discriminatory exclusion. These frameworks draw on empirical patterns showing that groups exhibiting behaviors such as stable family formation, high educational investment, and future-oriented decision-making tend to achieve better results, even amid historical adversities. Thomas Sowell argues in Discrimination and Disparities that cultural factors like attitudes toward work, savings, and punctuality explain variations in group performance more robustly than discrimination alone, as evidenced by divergent trajectories among immigrant cohorts facing similar barriers.[125][126] For instance, Jewish and Asian immigrants in the United States overcame exclusionary laws through cultural emphases on literacy and entrepreneurship, yielding intergenerational gains independent of legal equality.[125] Family structure exemplifies a behavioral factor with strong empirical links to outcomes. Children in single-parent households experience higher poverty rates and reduced upward mobility, with studies isolating this effect from race or income confounders. U.S. data from 2023 indicate that 49.7% of Black children lived with one parent, versus 20.2% of white children, correlating with elevated risks of economic dependency and criminal involvement.[127][128] Research further demonstrates that intact two-parent families buffer against these risks by providing dual-role models and resource stability, suggesting that cultural norms discouraging early nonmarital childbearing could mitigate disparities more effectively than anti-discrimination measures.[129][130] Cultural orientations toward education and effort similarly drive group differences. Asian Americans' superior academic performance stems from parental expectations of diligence, extended study hours outside school, and utilization of ethnic networks for tutoring, rather than innate advantages or discrimination deficits.[131] Peer-reviewed analyses confirm that these behaviors—such as higher homework completion rates and delayed gratification—account for achievement gaps, with family socioeconomic status exerting weaker influence on Asian outcomes compared to other groups.[132] In contrast, subgroups with norms prioritizing immediate consumption over skill-building exhibit persistent lags, underscoring how modifiable cultural practices shape human capital accumulation.[133] These analyses extend to labor market behaviors, where traits like reliability and skill acquisition influence hiring and advancement. Sowell's cross-national comparisons reveal that groups adopting bourgeois values—thrift, family cohesion, and occupational specialization—rapidly ascend socioeconomic ladders, as seen in West Indian Blacks outperforming native-born counterparts in early 20th-century Britain.[125] Empirical reviews of poverty persistence affirm that behavioral adaptations, not fixed discrimination, dominate long-term trajectories, with time horizons and health habits mediating socioeconomic health disparities.[134][135] While past discrimination may have eroded certain cultural capital, evidence indicates that internal reforms in values and incentives yield faster convergence than external attributions.[136]Empirical Assessments
Methodologies for Detecting Discrimination
Field experiments, particularly correspondence studies, represent a primary methodology for detecting discrimination by submitting nearly identical applications or inquiries that vary only in a signal of group membership, such as names implying race or gender, and comparing response rates like callbacks or offers.[137] These tests isolate causal effects of perceived traits by minimizing confounds from productivity differences, with over 80 such experiments conducted since 2000 across 23 countries in labor and housing markets.[138] For instance, a 2004 study sent resumes to Chicago job ads, finding white-sounding names received 50% more callbacks than black-sounding names with identical qualifications, suggesting taste-based or statistical bias against the latter.[137] Limitations include potential correlations between name signals and unobserved traits like cultural fit, and lower statistical power from low response rates, which can bias estimates toward underdetecting discrimination if low-quality resumes are used.[138] Observational methods, such as regression analysis and Oaxaca-Blinder decompositions, assess discrimination by controlling for observable factors like education and experience to attribute residual outcome disparities—e.g., wage gaps—to unexplained group effects potentially indicating bias.[139] In wage studies, these decompose differences into endowment (productivity-related) and coefficient (price or discrimination) components, with the latter interpreted as evidence of unequal treatment if productivity is fully controlled.[139] A critique arises from omitted variable bias: unmeasured factors, such as behavioral traits or network effects correlated with group identity, may explain residuals rather than animus, leading to overattribution of discrimination, especially in datasets from institutions prone to emphasizing structural explanations over individual agency.[140] Economists distinguish taste-based discrimination (prejudice-driven) from statistical discrimination (rational inference from group averages), where the latter persists even without bias if groups differ in unobservables, complicating causal identification without randomization.[141] Emerging frameworks for systemic discrimination extend these by modeling indirect effects, where prior discriminatory decisions propagate disparities through sequential choices, measured via dynamic models tracking total versus direct effects.[142] For example, a 2024 model classifies discrimination into direct (identity-based), systemic (cascading from past acts), and total, applied to audit data to quantify how early biases amplify later gaps, though empirical validation requires longitudinal data often unavailable.[143] Critiques highlight that such methods risk confounding legitimate statistical inference with prejudice, as group averages reflect real productivity variances from cultural or behavioral factors, not just historical exclusion; meta-analyses of field experiments show persistent but stable racial hiring gaps since the 1990s, unchanged by anti-discrimination laws, suggesting entrenched non-prejudicial mechanisms.[72][141] Overall, combining experimental and observational approaches strengthens inference but demands caution against assuming residuals equate to animus without ruling out efficiency-based alternatives.Evidence from Disparity Studies
Disparity studies examine differences in socioeconomic outcomes, such as employment rates, wages, and contract awards, between demographic groups to assess potential discrimination. These analyses often compare raw gaps and then apply statistical controls for factors like education, experience, and location, with persistent differences sometimes attributed to bias. However, such inferences require caution, as unobservable variables like productivity, cultural preferences, or behavioral differences can explain residuals, and many studies assume group equivalence that empirical data challenges.[144][145] In hiring, correspondence or audit studies provide direct evidence by submitting identical resumes varying only in signals of race, gender, or other traits. A seminal 2004 study found that resumes with white-sounding names received 50% more callbacks than those with black-sounding names in U.S. labor markets, suggesting taste-based discrimination in initial screening. A 2024 field experiment replicating this across multiple U.S. cities confirmed persistent bias, with black applicants receiving about 9% fewer callbacks than equally qualified white applicants, unchanged from prior decades. Meta-analyses of such studies indicate moderate racial discrimination against black and Hispanic candidates, with callback gaps of 20-36%, though effects vary by occupation and region; gender discrimination appears weaker and declining, particularly outside male-dominated fields.[75] These findings hold in controlled settings but capture only entry barriers, not retention or promotion, and may overstate impacts if applicants self-select into easier-to-penetrate firms.[146] Wage disparity analyses reveal raw gaps—e.g., in 2019, median black hourly earnings were 73.5% of white earnings, and women's 82% of men's—but controls for measurable factors like hours worked, occupation choice, and education reduce these substantially.[147] A National Bureau of Economic Research analysis showed that adjusting for cognitive ability (via Armed Forces Qualification Test scores) and premarket skills eliminates nearly all black-white wage gaps for young adults, implying disparities stem more from skill differences than post-hire discrimination.[144] Similarly, gender pay gaps shrink to 3-7% after accounting for work history interruptions, negotiation behaviors, and industry segregation, with little evidence of widespread employer bias in compensation once employed. Peer-reviewed critiques note that disparity studies often fail to fully control for group differences in effort, risk tolerance, or family priorities, leading to overattribution to discrimination; for instance, Asian American earnings exceed whites' despite historical biases, highlighting cultural or selection effects.[145] In public contracting, disparity studies compare minority-owned firm utilization to availability, inferring discrimination from shortfalls. A 2024 meta-analysis of 58 U.S. state and local studies found average utilization rates 20-40% below availability for black- and Hispanic-owned firms, prompting affirmative action claims.[148] Yet, federal reviews criticize these as unreliable proxies, since disparities may reflect firm capacity, bidding competitiveness, or subcontracting networks rather than bias; qualitative evidence often shows no intent, and remedies like set-asides can exacerbate inefficiencies without addressing root causes.[145][149] Overall, while audit evidence supports isolated discriminatory acts, aggregate disparities align more closely with differential human capital and choices than systemic barriers, per longitudinal data tracking outcomes over decades.[150]Critiques of Overstated Discrimination Claims
Critics contend that claims of widespread discrimination often attribute group disparities in outcomes—such as income, education, or employment rates—primarily to bias, overlooking alternative explanations rooted in behavioral, cultural, and socioeconomic factors. Economist Thomas Sowell argues in Discrimination and Disparities (2018, revised 2019) that statistical differences between groups are ubiquitous across history and societies, yet they frequently arise from prerequisites for success specific to endeavors, including geography, culture, and individual choices, rather than pervasive discrimination.[119] For instance, Sowell cites intra-group variations, such as higher achievement among West Indian blacks in the U.S. compared to native-born blacks despite shared discrimination histories, suggesting internal cultural dynamics play a larger role.[118] Audit studies, which send fictitious resumes varying by race or gender to gauge callback rates, have been central to discrimination claims but face methodological critiques for overstating effects. A 2017 meta-analysis of 28 U.S. field experiments found callback discrimination against African Americans persisted at similar levels from the 1990s to 2010s, implying stability rather than escalation, yet critics note that resumes rarely match perfectly on unobservables like motivation or networks, potentially inflating perceived bias.[151] A 2024 study sending 80,000 fake resumes confirmed modest racial gaps (e.g., 9% fewer callbacks for Black applicants), but emphasized these represent hiring stages, not overall labor market outcomes, and controls for qualifications reduce unexplained variance.[152] Similarly, a meta-analysis of gender bias in hiring found no statistically significant discrimination at the aggregate level across U.S. studies, with effects varying by context and often attributable to applicant differences beyond gender signals.[79] In wage disparities, regression analyses controlling for occupation, hours worked, experience, and education explain most of the raw gender pay gap, leaving a residual of 4-7% potentially due to unmeasured factors like negotiation or preferences, not necessarily discrimination.[153] For racial gaps, Sowell highlights how cultural emphases on education and family structure—evident in Asian American overperformance despite historical exclusion—correlate more strongly with outcomes than discrimination indices.[154] Peer-reviewed reviews affirm that while discrimination contributes, assuming it as the default cause ignores evidence from immigrant group trajectories, where low-discrimination environments yield similar disparities explained by pre-migration behaviors.[118] These critiques underscore a causal realism: discrimination exists but is often overstated when disparities are presumed discriminatory absent rigorous controls for confounders, leading to policies that may misdirect resources from addressable factors like skills development. Sowell's analysis, drawing on international data (e.g., higher female labor participation in some developing nations without U.S.-style affirmative action), illustrates how outcomes improve through internal group adaptations rather than external bias reduction alone.[124] Empirical tests, such as those isolating cultural variables in econometric models, consistently show they outperform discrimination proxies in explanatory power for persistent gaps.[120]Legal and Policy Frameworks
International Treaties and Standards
The foundational international standard prohibiting discrimination is the Universal Declaration of Human Rights, adopted by the United Nations General Assembly on December 10, 1948. Article 2 stipulates that everyone is entitled to all rights and freedoms without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth, or other status.[155] Although non-binding, the Declaration has influenced subsequent treaties and customary international law, serving as a benchmark for state obligations despite lacking enforcement mechanisms.[156] Binding treaties emerged in the post-World War II era to codify anti-discrimination norms. The International Convention on the Elimination of All Forms of Racial Discrimination (ICERD), adopted on December 21, 1965, and entering into force on January 4, 1969, defines racial discrimination as any distinction, exclusion, or preference based on race, colour, descent, or national or ethnic origin that impairs human rights.[157] States parties commit to prohibiting and eliminating such discrimination in all fields through legislation, policy, and education, with the Committee on the Elimination of Racial Discrimination monitoring compliance via state reports. As of 2023, 182 states have ratified ICERD, though reservations by some limit its scope, such as exclusions for certain indigenous or citizenship-based policies.[158][159] Gender-based discrimination is addressed by the Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW), adopted on December 18, 1979, and entering into force on September 3, 1981. It defines discrimination as any distinction, exclusion, or restriction made on the basis of sex that impairs women's enjoyment of human rights in political, economic, social, cultural, civil, or other fields.[160] CEDAW requires states to modify social and cultural patterns perpetuating sex-based stereotypes and ensure equality in employment, education, and health, monitored by a committee reviewing periodic reports. By 2025, 189 states have ratified it, with the United States signing but not ratifying due to concerns over sovereignty and potential conflicts with domestic law.[161][160] Employment discrimination falls under International Labour Organization Convention No. 111, adopted on June 25, 1958, and entering into force on June 15, 1960. It prohibits distinctions, exclusions, or preferences based on race, colour, sex, religion, political opinion, national extraction, or social origin that nullify equal opportunities in access to vocational training, employment, and occupation.[162] Exceptions are permitted for inherent job requirements or affirmative measures to advance disadvantaged groups, with over 175 ratifications reflecting broad acceptance among ILO members.[163]| Treaty/Convention | Adoption Year | Entry into Force | Ratifications (as of latest data) | Core Focus |
