Let’s talk about how the very first reader would vote. If they judged the post high quality, then they would multiply the prior likelihood ratio (6:4) times the bayes factor for a high private signal (4:1), get (6 4:4 1) = (6:1) and vote the post up.
Voting is a decision, so you need utility in order to go from 6:1 to “vote up”.

I agree. I should have said something about it, but at that point I’m using the assumption “Voters strive to vote the true quality of the post.”
