A new season of Pew's "After the Fact" podcast explores diversity in America and how race intersects with research in a range of fields—from public opinion polling to medicine to economics. We talk with social scientists who are helping society better understand how the nuances of race can change the perspective of issues and other experts who are looking at how diverse viewpoints improve policy solutions. The episodes of this season are a contribution to the evolving national conversation about race and diversity, offering a timely look at the challenges, opportunities—and the work—ahead.
