Several of the papers in this special issue are in one way or another linked to Cooke’s ‘‘classical’’ method for combining expert probability distributions. This comment focuses on characteristics of that method. In particular, I consider two questions: does the weighting scheme give the experts a positive incentive to report their beliefs honestly for each variable? How does Cooke’s method perform when evaluated out-of-sample? r 2008 Elsevier Ltd. All rights reserved.
