QUOTE=DMC]I just posted a link that showed for any given rape North Carolina, in the last year that statistics are available, the odds of it being a white rapist with a black victim are about the same as hitting a picked number in roulette, getting 2 sixes in a row with a standard die, or flipping heads 5 times in a row with a coin. Prior to responding to the post you made 10 minutes ago, I flipped a coin for a few minutes and actually got 6 heads in a row. So in this case, no, the odds do absolutely nothing to discount her credibility. She might be lying, and she might be telling the truth, but the odds themselves neither give credence, nor take away from it in this case.

Your conclusion does not follow from your premise. More on this later.
I do agree that if your statistic is accurate, and Huerta’s is not, the predictive value is lessened. That’s because, using your stat, the event in question is more common
Your experiment doesn’t increase either your credibility or the likelihood of the event, though. I put it that way, because I’m not sure exactly what you are claiming.
Possibility A: You are saying that your experiment shows that I am just as likely to succeed in an attempt get 6 heads outcomes as I am to fail in that attempt. (I hope you are not saying that, because it would be moronic. But if so, let’s play poker sometime.)
Possibility B: You are saying that your experiment shows that statistically unlikely events aren’t impossible. If so, I agree. (That doesn’t mean the statistic is valueless as a predictor, though.)
Possibility C: You are saying that your experiment shows that I cannot use statistics to evaluate the truth of your claim to have successfully obtained an unlikely outcome. If so, I disagree. Nothing can be proven, certainly. But in the absence of other evidence, a claimed event that is unlikely is less believable. (If you tell me you saw an animal walk down your city street today, my willingness to believe you is very high if the claimed animal was a dog, lessened (very slightly) if you say it was a Great Dane, reduced more if you claim it was a horse, further diminished if you say it was a gorilla, near-zero if you claim it was a white rhino, and zero if if say it was a unicorn.) Why is this so foreign to some of you?
