 What’s stated here is only a preliminary version. More sophisticated versions are developed by Lipton (2004: ch. 7) and Weisberg (2009a). This view is resisted by some Bayesians to varying degrees. van Fraassen (1989: ch. 7) argues that IBE should be rejected because it is in tension with the two core Bayesian norms. Okasha (2000) argues that IBE only serves as a good heuristic for guiding one’s credence change. Henderson (2014) argues that IBE need not be assumed to guide one’s credence change because it can be justified by little more than the two core Bayesian norms. For more on IBE, see the entry on  abduction,  in which sections 3.1 and 4 discuss explanationist Bayesianism.
