Episode notes

Bayes' theorem says that you have a prior credence or probability that you're giving to various propositions and then it tells you how to update your credences when new evidence comes in. The idea of Bayesian epistemology is that that's how knowledge works. We start with a whole bunch of credences for different propositions, then we update them when we get new information coming in. If only we actually did that, that would be great.

Welcome to the April 2023 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy!
