Imagine two Olympians who are equally trained, equally fit, equally talented. Is there a way to tell which athlete will win, and which athlete will choke? Vikram Chib, an assistant professor of biomedical engineering at Johns Hopkins, says that if he could compare their brain scans, he’d have a good idea about which one is most likely to choke under pressure.
The JHU Exploration of Practical Ethics provides funds for nine projects—some of which are still under way—that examine issues relating to criminal justice, higher education, economics, and environmentalism.
