Dorothy Roberts discusses some of the problems with race-based medicine. Before seeing the TED talk, I didn't realize that there were so many issues. These issues include poor study design (eg, asking a question about social race identification when the study was supposed to measure biological traits), historical and current biases (eg, using a different set of numbers in blood tests or physical tests because of assumptions that black people have more muscle mass without actually measuring the muscle mass), and obscuring some of the social determinants of health outcome (eg, food deserts).
Roberts' arguments were very compelling, and I highly recommend the talk to folks who are interested in medicine and/or race.
