They affect the likelihood (or our handicapping of the likelihood) that it took place as reported by the accuser, which is what we have to go on because she and the players are the ONLY ones who know what happened in that bathroom. Her allegations are the triggering event for the indictment of two guys who have a lot to lose. Her allegations are what the DA is going on (PROOF: If she had not made the allegations, there would be no case).
If her allegations are true, the event took place.
If her allegations are not true, it did not (unless some imagines some weird bizarro subset of cases where she’s totally lying about what happened, but was in fact raped anyhow).
Thus, the truth of her allegations is highly relevant to (determinative of) the occurrence vel non of the event.
Thus, we may for first order purposes (and in absence of other determinative evidence) treat “truthfulness of allegations” as identical to “occurrence of event.”
Thus, I posit, one may in evaluating “likelihood of truthfulness of allegations” take into account all factors suggestive thereof.
If one has reason to doubt the past truthfulness of the allegate-or, one may take that into account in ballparking the likelihood of “truthfulness of current allegations.”
If one finds the concatenation of alleged circumstances that would have to come into play unlikely (i.e., there are five red balls in a bag of twenty balls and the picker self-reports that she blindly picked them out five in a row), one may also consider that in setting a percentage for “likely truthfulness of allegation” and thus (in the absence of direct proof of “occurrence”), by proxy, “likely occurrence of given event.”
You may not like it but since we’re all speculating, I prefer my method to the head-in-sand one.
And, I’d make a heck of a lot more money by the end of the season in a sportsbook with this approach than you would by a blind insistence that there’s no reason the Houston Texans (2-14) should be expected to do worse than the Indianapolis Colts (14-2), just because of past records, and the rarity of personnel-challenged, undersized teams suddenly reversing their fortunes. My predictions of what would in fact happen in 2006 would be (in fact) right in more (not all) instances than would a random-walk.
