Respectfully, that sounds like the “catch” here, though I doubt you have any actual ill intentions. If it applies at any point within the period, then it could apply for something as simple as a brief miscommunication from the White House that gets resolved within 24 hours. Some overworked and underpaid headline-writer makes a critical typo, aliens suddenly seem confirmed to LWers, and then… it’s game?
I would strongly recommend that you amend that edge case interpretation to only consider the state of things at the end of the period. While there could still technically be a spike of credulity around that time, it would be quite unlikely, whereas if UFOs have actually properly been established at some point in that time period, they will remain so throughout.
A proper Bayesian currently at less 0.5% credence for a proposition P should assign a less than 1 in 100 chance that their credence in P rises above 50% at any point in the future. This isn’t a catch for someone who’s well-calibrated.
In the example you give, the extent to which it seems likely that critical typos would happen and trigger this mechanism by accident is exactly the extent to which an observer of a strange headline should discount their trust in it! Evidence for unlikely events cannot be both strong and probable-to-appear, or the events would not be unlikely.
If the purpose of this betting is to reward those who bet on the truth, though, then allowing a spike in credulity to count for it works against that purpose, and turns it into more of a combined bet of “Odds that the true evidence available to the public and LW suggests >50% likelihood or that substantial false evidence comes out for a very short period within the longer time period”.
In his comment reply to me, OP mentioned he would be fine with a window of a month for things to settle and considered it a reasonable concern, which suggests that he is (rightly) focused more on betting about actual UFO likelihood, rather than the hybrid likelihood that includes hypothetical instances of massive short-term misinformation.
While you are correct that the probability of that misinformation should theoretically be factored in on the better’s end, that’s not what the OP is really wanting to bet on in the first place; as such, I don’t think it was a mistake to point it out.
That’s a reasonable concern. My concern is that without some principal to avoid it, that would just mean that everyone waits out the full 5 years even if its clear I’m the winner.
I wouldn’t mind giving a window of a month for things to settle before there’s a duty to settle. I would still demand that if anyones credence ever goes >50% that they still have to register that publicly (or at least to me)

That sounds reasonable enough.
