Robustness, Diversity of Evidence, and Probabilistic Independence

Part of the European Studies in Philosophy of Science book series (ESPS, volume 1)

Abstract

In robustness analysis, hypotheses are supported to the extent that a result proves robust, and a result is robust to the extent that we detect it in diverse ways. But what precise sense of diversity is at work here? In this paper, I show that the formal explications of evidential diversity most often appealed to in work on robustness – which all draw in one way or another on probabilistic independence – fail to shed light on the notion of diversity relevant to robustness analysis. I close by briefly outlining a promising alternative approach inspired by Horwich’s (Probability and evidence. Cambridge University Press, Cambridge, 1982) eliminative account of evidential diversity.
