Bayesian epistemology is based upon the 'simple rule' (believe P if it is sufficiently probable) and Bayes' Theorem.

Clarification

'Bayes' Theorem' is an equation for assessing probability

Gist of Idea

Bayesian epistemology is Bayes' Theorem plus the 'simple rule' (believe P if it is probable)

A Reaction

For Bayes' Theorem, see Idea 2798. There is the question of whether the proposition is subjectively or objectively probable (I believe in ghosts, so any shadow is probably a ghost). There is also the problem of objective evidence for the calculation.

The 15 ideas with the same theme [areas of interest concerning justification]:

If we need a criterion of truth, we need to know whether it is the correct criterion [Pyrrho, by Fogelin]
It is common to doubt truth when discussing it, but totally accept it when discussing knowledge [Davidson]
Reasons can either be facts in the world, or intentional states [Searle]
Must all justification be inferential? [Ginet]
Inference cannot originate justification, it can only transfer it from premises to conclusion [Ginet]
A 'warrant' is a process which ensures that a true belief is knowledge [Kitcher]
Is it people who are justified, or propositions? [Williams,M]
Bayesian epistemology is Bayes' Theorem plus the 'simple rule' (believe P if it is probable) [Pollock/Cruz]
Justification can be of the belief, or of the person holding the belief [Bernecker/Dretske]
Knowing you know (KK) is usually denied if the knowledge concept is missing, or not considered [Williamson]
Modern epistemology centres on debates about foundations, and about external justification [O'Grady]
The 'warrant' for a belief is what turns a true belief into knowledge [Merricks]
Don't confuse justified belief with justified believers [Dougherty/Rysiew]
Epistemic is normally marked out from moral or pragmatic justifications by its truth-goal [Vahid]
'Modal epistemology' demands a connection between the belief and facts in possible worlds [Black,T]
