[3] Research has uncovered extensive evidence of discrimination based on skin color in criminal justice, business, the economy, housing, health care, the media, and politics in the United States and Europe.In addition to this issue being documented in the United States, lighter skin tones have been considered preferable in many countries in Africa, Asia, and Latin America.Research shows that ethnic minorities are offered fewer opportunities in higher education and employment, are subject to increased scrutiny by police, and are less likely to receive adequate care from physicians.[6][7][8] A 2016 meta-analysis of 738 correspondence tests in 43 separate studies done in OECD countries in 1990–2015 finds that there is extensive racial discrimination within both the European and North American hiring processes.[13][15] Der Spiegel reports that in Ghana, "When You Are Light-Skinned, You Earn More", and that "[s]ome pregnant women take tablets in the hopes that it will lead their child to be born with fair skin.In the ancient dynastic eras, to be light in an area where the sun was harsh implied wealth and nobility, because those privileged persons could stay indoors while servants had to labor outside.[29] The legacy of this 'Eurasian' beauty ideal continues to be reflected in local literature, as it was written in a popular novel that "a golden colored skin is the greatest gift Allah can bestow upon a woman", in reference to a blonde-haired girl who did not inherit her grandmother's complexion.[19] Multiple studies have concluded that preference for lighter skin in India is historically linked to both the caste system and centuries of rule by peoples from other areas: Persia, Mughal territory, and Europe.A light complexion is equated with male and female beauty, racial superiority, and power and continues to have strong influences on marital prospects, employment, status, and income.As these mechanisms interplay with the presence of existent capitalistic institutions that control much of today's world, the skin-lightening industry benefits this system through the exploitation of vulnerable individuals.[51][52] In the wake of the murder of George Floyd, an African-American man in the United States, which led to protests against racism worldwide, the debate about colorism and skin tone in India has been discussed in several media outlets.Because Mexico consists of ethnic, cultural, and linguistic diversity, many Mexicans argue that darker-skinned citizens tend to live in historically disadvantaged and highly indigenous areas.A parallel as well as an opposite critique of this theory is made by black scholars, who state that racial neutrality will not eliminate discrimination based on skin color as long as some races continue to be negatively perceived and unfairly treated.For those who harbor such fears, the browning of America brings with it yet another opportunity for the nation to evade social justice.Several authors have noted that a kind of reverse-colorism began to form within the African-American community after the end of slavery.[6] A 1995 study found that car dealers "quoted significantly lower prices to white males than to black or female test buyers using identical, scripted bargaining strategies.[99] In 2018, a study was published by Dr. Joy Buolamwini and Timnit Gebru evaluating the accuracy of several facial recognition technologies in identifying male and female individuals of varying skin tones.[115] A 2018 study in the journal Proceedings of the National Academy of Sciences found that tall young black men are especially likely to receive unjustified attention by law enforcement.[5] A 2016 study by Roland G. Fryer, Jr., of the National Bureau of Economic Research (NBER) found that while overall "blacks are 21 percent more likely than whites to be involved in an interaction with police in which at least a weapon is drawn" and that in the raw data from New York City's Stop and Frisk program, "blacks and Hispanics are more than fifty percent more likely to have an interaction with police which involves any use of force" after "[p]artitioning the data in myriad ways, we find no evidence of racial discrimination in officer-involved shootings."[124] The study did find bias against blacks and Hispanics in non-lethal and less-extreme lethal violence, stating that "as the intensity of force increases (e.g. handcuffing civilians without arrest, drawing or pointing a weapon, or using pepper spray or a baton), the probability that any civilian is subjected to such treatment is small, but the racial difference remains surprisingly constant", and noting that "[u]ntil recently, data on officer-involved shootings were extremely rare and contained little information on the details surrounding an incident".[127] Reports by the Department of Justice have also found that police in Baltimore, Maryland, and Ferguson, Missouri, systemically stop, search (in some cases, strip-search), and harass black residents.[174] Pulse oximeters are a medical device that is commonly attached to a patient's finger and uses a sensor to measure light that has traveled through the skin to determine oxygen saturation in blood.[199] A 2017 study in Research & Politics found that white supporters of Donald Trump became less likely to approve of federal housing assistance when they were shown an image of a black man.[202] A 2018 experimental study by University of Illinois and Duke University economists found that real estate agents and housing providers systematically recommended homes in neighborhoods with higher poverty rates, greater pollution, higher crime rates, fewer college-educated families, and fewer skilled workers to minority individuals who had all the same characteristics as white individuals except ethnic differences.[203] A 2018 study in the American Political Science Review found that white voters in areas that experienced massive African-American population growth between 1940 and 1960 were more likely to vote for California Proposition 14 (1964), which sought to enshrine legal protections for landlords and property owners who discriminated against "colored" buyers and renters.Animal print reinforces the stereotypes that African Americans are animalistic in nature, sexually active, less educated, have lower income, and are extremely concerned with their personal appearances.[238] A 2009 study of the 2006 midterm election nationwide found that 47% of white voters reported being asked to show photo identification at the polls, compared with 54% of Hispanics and 55% of African Americans.[240] A 2016 study by University of California, San Diego researchers found that voter ID laws "have a differentially negative impact on the turnout of Hispanics, Blacks, and mixed-race Americans in primaries and general elections."[241] Research by University of Oxford economist Evan Soltas and Stanford political scientist David Broockman suggests that voters act upon racially discriminatory tastes.Although her camp denied the accusations, the intention, whether apparent or not, stems from the system of colorism and viewing or equating darker skin tones as bad and in a negative light.Additionally, concerns about winning the votes of white men can cause voters to rate black and female Democratic candidates as less capable of beating Donald Trump in 2020.
