Explore the outreach toolkit, view upcoming screening events, and browse support materials for two NOVA films – Critical Condition: Health in Black America and When Machines Prescribe.
In <a href="https://www.pbs.org/wgbh/nova/video/critical-condition-health-in-black-america/">Critical Condition: Health in Black America</a>, Oscar-nominated and Emmy award-winning filmmaker Stanley Nelson investigates the dramatic health disparities in the US, even as scientists confirm that there are no meaningful genetic differences between races. From the deep history of pseudoscientific beliefs about race that still permeate modern medicine, to the latest research on how experiencing discrimination can directly damage the body’s DNA and biology, Critical Condition reveals the factors behind the health crisis facing Black Americans.The accompanying short documentary, <a href="https://www.pbs.org/wgbh/nova/video/when-machines-prescribe/">When Machines Prescribe</a>, produced by Llew Smith and Kelly Thomson, investigates the use of race in clinical algorithms. Designed to weigh factors like symptoms, medical history, and test results to achieve the best possible outcomes for patients, some common medical algorithms were built using data based on old pseudoscience about racial differences and their continued use has harmed the health of Black patients.<a href="https://www.pbs.org/wgbh/nova/video/critical-condition-health-in-black-america/">Critical Condition</a> and <a href="https://www.pbs.org/wgbh/nova/video/when-machines-prescribe/">When Machines Prescribe</a> are both available to stream on NOVA's website and the <a href="https://www.pbs.org/pbs-app/">PBS app</a>.
