Theories about the origins of racism

Sociological model of ethnic and racial conflict Evolutionary psychologists John Tooby and Leda Cosmides were puzzled by the fact that in the US, race is one of the three characteristics most often used in brief descriptions of individuals (the others are age and sex). They reasoned that natural selection would not have favoured the evolution of an instinct for using race as a classification, because for most of human history, humans almost never encountered members of other races. Tooby and Cosmides hypothesized that modern people use race as a proxy (rough-and-ready indicator) for coalition membership, since a better-than-random guess about "which side" another person is on will be helpful if one does not actually know in advance.

Their colleague Robert Kurzban designed an experiment whose results appeared to support this hypothesis. Using the memory confusion protocol, they presented subjects with pictures of individuals and sentences, allegedly spoken by these individuals, which presented two sides of a debate. The errors that the subjects made in recalling who said what indicated that they sometimes mis-attributed a statement to a speaker of the same race as the "correct" speaker, although they also sometimes mis-attributed a statement to a speaker "on the same side" as the "correct" speaker. In a second run of the experiment, the team also distinguished the "sides" in the debate by clothing of similar colors; and in this case the effect of racial similarity in causing mistakes almost vanished, being replaced by the color of their clothing. In other words, the first group of subjects, with no clues from clothing, used race as a visual guide to guessing who was on which side of the debate; the second group of subjects used the clothing color as their main visual clue, and the effect of race became very small.

Some research suggests that ethnocentric thinking may have actually contributed to the development of cooperation. Political scientists Ross Hammond and Robert Axelrod created a computer simulation wherein virtual individuals were randomly assigned one of a variety of skin colors, and then one of a variety of trading strategies: be color-blind, favor those of your own color, or favor those of other colors. They found that the ethnocentric individuals clustered together, then grew, until all the non-ethnocentric individuals were wiped out.

In The Selfish Gene, evolutionary biologist Richard Dawkins writes that "Blood-feuds and inter-clan warfare are easily interpretable in terms of Hamilton's genetic theory." Dawkins writes that racial prejudice, while not evolutionarily adaptive, "could be interpreted as an irrational generalization of a kin-selected tendency to identify with individuals physically resembling oneself, and to be nasty to individuals different in appearance." Simulation-based experiments in evolutionary game theory have attempted to provide an explanation for the selection of ethnocentric-strategy phenotypes.

Despite support for evolutionary theories relating to an innate origin of racism, various studies have suggested racism is associated with lower intelligence and less diverse peer groups during childhood. A neuroimaging study on amygdala activity during racial matching activities found increased activity to be associated with adolescent age as well as less racially diverse peer groups, which the author conclude suggest a learned aspect of racism. A meta-analysis of neuroimaging studies found amygdala activity correlated to increased scores on implicit measures of racial bias. It was also argued amygdala activity in response to racial stimuli represents increased threat perception rather than the traditional theory of the amygdala activity represented ingroup-outgroup processing. Racism has also been associated with lower childhood IQ in an analysis of 15,000 people in the UK.

Psychological causes

A 2017 study in the American Political Science Review found that prejudice towards marginalized groups, such as refugees, could be explained by a failure to take the perspective of the marginalized group.The study found that young Hungarian adults who played a perspective-taking game (a game intended to reduce prejudice towards marginalized groups by having players assume the role of a member of a marginalized group) showed reduced prejudice towards Romani people and refugees, as well as reduced their vote intentions for Hungary's overtly racist, far right party by 10%.

State-sponsored racism

State racism—the institutions and practices of a nation-state that are grounded in racist ideology—has played a major role in all instances of settler colonialism, from the United States to Australia.[citation needed] It also played a prominent role in the Nazi German regime, in fascist regimes throughout Europe, and during the early years of Japan's Shōwa period. These governments advocated and implemented ideologies and policies that were racist, xenophobic, and, in the case of Nazism, genocidal.

The Nuremberg Race Laws of 1935 prohibited sexual relations between any Aryan and Jew, considering it Rassenschande, "racial pollution". The Nuremberg Laws stripped all Jews, even quarter- and half-Jews (second and first degree Mischlings), of their German citizenship. This meant that they had no basic citizens' rights, e.g., the right to vote. In 1936, Jews were banned from all professional jobs, effectively preventing them from having any influence in education, politics, higher education, and industry. On 15 November 1938, Jewish children were banned from going to normal schools. By April 1939, nearly all Jewish companies had either collapsed under financial pressure and declining profits, or had been persuaded to sell out to the Nazi government. This further reduced their rights as human beings; they were in many ways officially separated from the German populace. Similar laws existed in Bulgaria (The Law for protection of the nation), Hungary, Romania, and Austria.

Legislative state racism is known to have been enforced by the National Party of South Africa during its Apartheid regime between 1948 and 1994. Here, a series of Apartheid legislation was passed through the legal systems to make it legal for white South Africans to have rights which were superior to those of non-white South Africans. Non-white South Africans were not allowed involvement in any governing matters, including voting; access to quality healthcare; the provision of basic services, including clean water; electricity; as well as access to adequate schooling. Non-white South Africans were also prevented from accessing certain public areas, from using certain public transportation, and were required to live only in certain designated areas. Non-white South Africans were taxed differently than white South Africans and they were also required to carry on them at all times additional documentation, which later became known as "dom passes", to certify their non-white South African citizenship. All of these legislative racial laws were abolished through a series of equal human rights laws which were passed at the end of the Apartheid era in the early 1990s.

Human zoos

Human zoos (called "People Shows"), were an important means of bolstering popular racism by connecting it to scientific racism: they were both objects of public curiosity and of anthropology and anthropometry. Joice Heth, an African-American slave, was displayed by P.T. Barnum in 1836, a few years after the exhibition of Saartjie Baartman, the "Hottentot Venus", in England. Such exhibitions became common in the New Imperialism period, and remained so until World War II. Carl Hagenbeck, inventor of the modern zoos, exhibited animals beside humans who were considered "savages".

Congolese pygmy Ota Benga was displayed in 1906 by eugenicist Madison Grant, head of the Bronx Zoo, as an attempt to illustrate the "missing link" between humans and orangutans: thus, racism was tied to Darwinism, creating a social Darwinist ideology that tried to ground itself in Darwin's scientific discoveries. The 1931 Paris Colonial Exhibition displayed Kanaks from New Caledonia. A "Congolese village" was on display as late as 1958 at the Brussels' World Fair.
