Bayes theorem is simply a device to proci learned.

Also the definition is individual-specific. As pointed out viduals may differ in their reaction to the same information source. For example their prior probabilities may differ so that posterior probabilities and hence their decisions may differ even when confronted with the same evidence. The definition should really be interpreted net of cost.
