 In the past decade, Bayesian confirmation theory has firmly established itself as the dominant view on confirmation; currently one cannot very well discuss a confirmation-theoretic issue without making clear whether, and if so why, one’s position on that issue deviates from standard Bayesian thinking. Abduction, in whichever version, assigns a confirmation-theoretic role to explanation: explanatory considerations contribute to making some hypotheses more credible, and others less so. By contrast, Bayesian confirmation theory makes no reference at all to the concept of explanation. Does this imply that abduction is at loggerheads with the prevailing doctrine in confirmation theory? Several authors have recently argued that not only is abduction compatible with Bayesianism, it is a much-needed supplement to it. The so far fullest defense of this view has been given by Lipton (2004, Ch. 7); as he puts it, Bayesians should also be “explanationists” (his name for the advocates of abduction). (For other defenses, see Okasha 2000, McGrew 2003, Weisberg 2009, and Poston 2014, Ch. 7; for discussion, see Roche and Sober 2013, 2014, and McCain and Poston 2014.)
