If handling uncertanty caused by computational limitation is really a
standard part of Bayesianism, then show me a reference or textbook that
deals with this. None of the probability theory books I've read (for
example _Probability Theory: The Logic of Science_ by E. T. Jaynes
available online) talks about it. My understanding is that Bayesianism
only deals with uncertanties already present in one's prior information,
not ones introduced during one's reasoning process.
