In this lecture, Dr. Alondra Nelson considers the “politics of ethics” that was a signature of the Obama administration’s approach to science and technology. This politics of ethics endeavored to place temporal distance between scientific research of the past and present, enabling claims about the importance of federal science to national wellbeing, broadly conceived. In particular, she will examine the roll-out of the Precision Medicine Initiative that incorporated plainspoken acknowledgement of prior discrimination in government-backed scientific research as a necessary predicate to the successful enrollment of research subjects—especially those from minority populations--into the program.
