BAYESIANISM AND THE VALUE OF DIVERSE EVIDENCE

In a recent essay (1995), Andrew Wayne charges that Bayesian attempts to account for the rule that, ceteris paribus, diverse evidence confir ms better than narrow evidence are inadequate. I reply to these critic isms and argue that, on the contrary, one of the Bayesian approaches c onsidered by Wayne does an excellent job of explaining why, and under what circumstances, diverse evidence is valuable.
