The best thing I’ve listened to this month, by a comfortable margin, is Russ Roberts’ conversation with Jim Manzi, founder of Applied Predictive Technologies, author of Uncontrolled, and a contributor to NRO, on the Oregon Medicaid study, which builds on Jim’s recent essay on the subject. The exchange is a useful primer on the analysis of experimental data, and it raises lots of interesting questions about how the results of the study have been interpreted by the major newspapers.
