By the specified date there will be verifiable evidence proving the alien abduction phenomenon to be true.
I will judge based on the intent of this claim, if I perceive such intent to be obvious. If such intent is ambiguous I will judge on the basis of the precise wording. If both are ambiguous, I will look for a solution which follows IF/FX precedent insofar as such precedent is apparent to me and applicable to the claim. I will seek the guidance of the claim's owner/author in interpreting the claim. It's his or her question - s/he ought to get the answer sought. If I believe this claim to have met a YES or NO condition, and if I believe judgement will be controversial, I will post a prospective judgement to fx-discuss and forestall entering the judgement for a comment period to be announced in the post.
