### Single Idea 16802

#### [catalogued under 14. Science / C. Induction / 6. Bayes's Theorem]

Full Idea

Old evidence seems to provide some confirmation, but Bayesianism does not allow for this, since old evidence will have a prior probability of one, and so have no effect on the posterior probability of the hypothesis.

Gist of Idea

Bayes seems to rule out prior evidence, since that has a probability of one
