How covid-19 exposes systemic racism in America
- The murder of George Floyd triggered the largest civil rights protests in U.S. history, catalyzing a global movement against racism and police brutality.
- One year later, police reform legislation has expanded across the U.S., and the officer responsible for Floyd's death is incarcerated.
- The pandemic highlighted systemic racism as a direct life-or-death factor, with Black people in the U.S. facing nearly twice the risk of dying from COVID-19 compared to white people.
- Black patients were frequently misdiagnosed or turned away during the pandemic due to inaccurate pulse oximeter readings caused by device calibration on lighter skin.
- Pulse oximeters function by passing light through skin to measure oxygen levels, a mechanism calibrated predominantly using white subjects.
- Darker pigmented skin absorbs and reflects light differently than lighter skin, leading the devices to falsely indicate high oxygen saturation in Black patients even when they were critically ill.
- Disparities in health outcomes are driven by structural inequities rather than solely individual malice or explicit discrimination.
- Key structural factors include lack of access to quality healthcare, primary care physicians, pharmacies, jobs, and health insurance.
- These systemic gaps impact public health broadly, affecting communities beyond those directly marginalized, such as Hispanic and Native Americans.
- Structural racism is characterized as "racism without racists," where well-intentioned individuals perpetuate bias through unexamined systems and practices.
- Examples of this structural bias include facial recognition algorithms developed by white men and tested on lighter-skinned subjects, resulting in mistaken arrests of innocent Black Americans.
- Bias often emerges during the R&D phase (e.g., lack of diverse testing subjects) rather than from overt acts of discrimination in the field.
- Addressing these disparities is complicated because they lack obvious "villains," making it difficult to assign blame and implement fixes compared to issues caused by explicit bad actors.
- Closing these gaps requires deep reflection and confrontation of unconscious biases by institutions, as current methods often inadvertently perpetuate racial inequality.
- Solving the problem involves two steps: identifying the structures that created the disparity and determining actionable steps to correct them.
- Overcoming defensive reactions to these revelations is a necessary hurdle for promoting equitable outcomes.
