Abstract

According to the dominant interpretation of the likelihood approach to hypothesis ranking, likelihoods are supposed to be conditioned on the available background information. In doing so, background information about the manner in which evidence was obtained can obliterate the value of that evidence for discriminating amongst hypotheses. I argue that this interpretation conflates two distinct questions concerning the support offered by evidence, and derive appropriate expressions for addressing each.
