Bayesian and approach
Those who promote Bayesian inference view " frequentist statistics " as an approach to statistical inference that recognises only physical probabilities.

The reason is that the background knowledge which Good and others use can not be expressed in the form of a sample proposition-in particular, variants of the standard Bayesian approach often suppose ( as Good did in the argument quoted above ) that the total numbers of ravens, non-black objects and / or the total number of objects, are known quantities.
Hintikka was motivated to find a Bayesian approach to the paradox which did not make use of knowledge about the relative frequencies of ravens and black things.
This contrasts with the Bayesian approach, which requires that the hypothesis be assigned a prior probability, which is revised in the light of the observed data to obtain the final probability of the hypothesis.

Although this will result in choosing the same action as would be chosen using the Bayes risk, the emphasis of the Bayesian approach is that one is only interested in choosing the optimal action under the actual observed data, whereas choosing the actual Bayes optimal decision rule, which is a function of all possible observations, is a much more difficult problem.
One approach, suggested by writers such as Stephen D. Unwin, is to treat ( particular versions of ) theism and naturalism as though they were two hypotheses in the Bayesian sense, to list certain data ( or alleged data ), about the world, and to suggest that the likelihoods of these data are significantly higher under one hypothesis than the other.
