Where prediction markets are used now

Robin Hanson, of George Mason University, argues that health care is different, but not in the usual ways people claim. He describes a set of paradoxical empirical findings in the study of health care and tries to explain these paradoxes in a unified way. One of his arguments is that the human brain evolved in ways that make it hard for us to be rational about health care. He also discusses using prediction markets as a way of designing health care policy.
