Of the ten clinical genetics labs in the United States that share the most data with the research community, seven include ‘Caucasian’ as a multiple-choice category for patients’ racial or ethnic identity, despite the term having no scientific basis. Nearly 5,000 biomedical papers since 2010 have used ‘Caucasian’ to describe European populations. This suggests that too many scientists apply the term, either unbothered by or unaware of its roots in racist taxonomies used to justify slavery — or worse, adding to pseudoscientific claims of white biological superiority.
