Scientific Racism

Since enslaved people were first brought to this country, promoters of anti-Black racism and white supremacy have co-opted the authority of science to justify racial inequality. A history of pseudoscientific methods "proving' white biological superiority and flawed social studies used to show "inherent" racial characteristics still influence society today.

In 1619, when the first enslaved people were brought to what would become the United States, justifications for their enslavement were brought here too. In the 400 years since then, as those enslaved and their descendants have continued to call this country home, the justifications for their abuse and mistreatment have stayed with us as well.

One of the most effective tactics used to justify anti-Black racism and white supremacy has been scientific racism. Through the years, scientific racism has taken many forms, all with the goal of co-opting the authority of science as objective knowledge to justify racial inequality.

Some 19th-century scientists, like Harvard's Louis Agassiz, were proponents of "polygenism," which posited that human races were distinct species. This theory was supported by pseudoscientific methods like craniometry, the measurement of human skulls, which supposedly proved that white people were biologically superior to Blacks. Early statistical health data was weaponized against Black Americans in the late 1800s, as it was used to claim they were predisposed to disease and destined for extinction.

By the early to mid-20th century, polygenism and biology-based racism were widely disproven, and racism in social science had gained popularity. Studies showing high rates of imprisonment among Black Americans were used as proof of innate criminality, while pseudoscientific intelligence testing claimed the mental superiority of white people. These flawed, biased studies failed to account for political and social factors such as poor housing, poverty, lack of healthcare, and virulent racial oppression. But they provided the so-called evidence needed to fuel systemic forms of anti-Black racism, like segregation. And, for many Americans looking for objective reasons to justify racist beliefs and behaviors, studies like these were more than enough.

Contemporary scientific consensus agrees that race has no biological basis, but scientific racism still exists. While it's now more subtle than craniometry, its long history demonstrates the influence social ideas about race can have on supposedly unbiased research.
