Why does race matter so profoundly for health? Dr. David R. Williams developed a scale to measure the impact of discrimination on well-being, going beyond traditional measures like income and education to reveal how factors like implicit bias, residential segregation and negative stereotypes create and sustain inequality. In this eye-opening talk, Dr. Williams presents evidence for how racism is producing a rigged system — and offers hopeful examples of programs across the US that are working to dismantle discrimination.
