Rotten apples, Lockean belief, and Booleanosis

May 3, 2013

The Lockean thesis maintains that an individual fully believes a proposition p just when he has a high level of confidence in p.  The received view has it that the problem with Lockean accounts of qualitative belief  is summed up by Henry Kyburg’s lottery paradox, which pits high-probability acceptance rules against the rule of adjunction. For Kyburg, there was no paradox, but instead a misplaced commitment to the rule of adjunction, a condition he famously described as “conjunctivitis”.  

Less observed is a problem for Lockean belief and disjunction (Kyburg, Teng, and Wheeler 2007). It turns out that Lockeans expose themselves to a pernicious form of amalgamation reversals (a.k.a., “Simpson’s paradox”) which cannot be handled by the known recipes for avoiding such reversals (Good and Mittal 1987).  Below the fold is an example and short discussion.

CMU Ockham’s Razor Workshop: Follow-up

June 27, 2012

The CMU Ockham’s Razor workshop was last weekend, and several participants have written up comments on their blogs:

Deborah Mayo, at her blog Error Statistics [here];

Cosma Shalizi, at his blog, Three-Toed Sloth  [Day 1, Day 2, Day 3] ;

Larry Wasserman, on his new blog, Normal Deviate [here], which also has a nice précis of Peter Grunwald’s talk on “Self-repairing Bayesian Statistics”.


Schervish on Strictly Proper Scoring Rules for Incentive-Compatible Elicitation

April 10, 2012

Mark Schervish, Professor and Head of the Department of Statistics at Carnegie Mellon University, will deliver a Games and Decisions lecture, “Incentive-Compatible Elicitation,” on Wednesday, April 11, 2012, at Carnegie Mellon University.

Schervish joined the Department of Statistics in 1979 after earning a doctoral degree in statistics from the University of Illinois at Urbana-Champaign and a master’s degree in applied mathematics from the University of Michigan. His research interests in statistics are broad, spanning problems concerning foundations, methodology, theory, and applications. In addition to numerous articles, Schervish is author of Theory of Statistics (Springer) and co-author of Rethinking the Foundations of Statistics (with Teddy Seidenfeld and Jay Kadane; CUP) and Probability and Statistics (with Morris H. DeGroot; Addison-Wesley). What follows is an abstract of his Games and Decisions lecture.

Strictly proper scoring rules have been advertised as tools that allow the elicitation of various aspects of subjective probability distributions by providing the proper incentives to induce agents to honestly report their beliefs. We give a brief overview and report some results that raise some questions about the ability to implement the incentive structure as intended. The results extend to all statistical decision problems and raise issues that should be addressed whenever applying statistical decision theory in practice.
