Uhrm, that's right, the value judgements weren't important to the point about probability, as I literally just said-- they'd let us skip a few steps later, that's all. But as you got so hung up on them, we can go for full tone neutrality.They also weren't important to my point about how the probability is irrelevant. Incredible.
Say instead there's a rare book in a shop window. One of the people who often comes to the shop is a fan of the author. An observer (who knows this) estimates at the start of the day that the probability of selling it on that day is 20% or so.
The fan passes by, and returns home, without coming in or spotting it.
The observer reestimates the likelihood of selling it that day. Do you think it's risen? Stayed the same? Decreased?
