Title: Probing with Severity: Beyond Bayesian Probabilism and Frequentist Performance
Time: 3:20 – 4:20pm, Wednesday, December 3, 2014 Place: 552 Hill Center
ABSTRACT
Probing with Severity: Beyond Bayesian Probabilism and Frequentist Performance Getting beyond today’s most pressing controversies revolving around statistical methods, I argue, requires scrutinizing their underlying statistical philosophies.Two main philosophies about the roles of probability in statistical inference are probabilism and performance (in the long-run). The first assumes that we need a method of assigning probabilities to hypotheses; the second assumes that the main function of statistical method is to control long-run performance. I offer a third goal: controlling and evaluating the probativeness of methods. An inductive inference, in this conception, takes the form of inferring hypotheses to the extent that they have been well or severely tested. A report of poorly tested claims must also be part of an adequate inference. I develop a statistical philosophy in which error probabilities of methods may be used to evaluate and control the stringency or severity of tests. I then show how the “severe testing” philosophy clarifies and avoids familiar criticisms and abuses of significance tests and cognate methods (e.g., confidence intervals). Severity may be threatened in three main ways: fallacies of statistical tests, unwarranted links between statistical and substantive claims, and violations of model assumptions.

Since 1986 Icahn School of Medicine has co-sponsored an annual series of day-long conferences, Issues in Medical Ethics. These conferences attract a broad audience of 150-200 participants including physicians, medical students, nurses and other health care providers, scientists, lawyers, academics, and graduate students. Speakers have come from medicine, philosophy, government, and law.
Each year’s conference focuses on a timely issue. Topics have included medical professionalism, organ transplantation, the Americans with Disabilities Act, money and access to health care. The proceedings of many of these conferences have appeared in special issues of The Mount Sinai Journal of Medicine. In February 2014, the conference topic was “Data Science and Digital Medicine.”
