I think this leans a lot on “get evidence uniformly over the next 10 years” and “Brownian motion in 1% steps”. By conservation of expected evidence, I can’t predict the mean direction of future evidence, but I can have some probabilities over distributions which add up to 0.
For long-term aggregate predictions of event-or-not (those which will be resolved at least a few years away, with many causal paths possible), the most likely updates are a steady reduction as the resolution date gets closer, AND random fairly large positive updates as we learn of things which make the event more likely.
