If four out of five people say one thing, it makes it more likely that what they say is true. That's the only point here. Witness testimony matters, and not only eye witness testimony. Beyond reasonable doubt isn't even in the equation here.
True, but I also said it has no bearing on the likelihood unless you can establish credibility, direct witness account, or some other relationship that establishes some sort of bearing on the truth. If I get 5 people to say something and believe it, it has no bearing on whether or not it's true, only that those people believe it. If they believe it for good reasons, then maybe it can start to have some bearing, but until such a time, the simple act of believing has no effect on the truth or even the likelihood of proof.
Given no evidence whatsoever, every proposition is "50/50". If I have no reason whatsoever to choose A or B, how can I say one is more likely than the other? The reason the number of people who believe either way is relevant is because they might know something.
No, this is a very common misconception. Given no indication or direction, you cannot form the probability space of a problem - it has unknowable probability. You can't say one is more likely than the other, but you can't say that they are equally likely either. You simply can't make any judgment as to their probabilities.
So are you saying that it would be more rational to pick B, C, or D? I'd like to hear the case for that.
No, I'm saying there is NO RATIONAL CHOICE.
You should because they might have knowledge on the subject. The fact that 80% picked A provides evidence that they DO have knowledge... otherwise why would such a strong majority pick A?
Do you know the probability that they might have knowledge? You might be able to form some quick probabilistic estimates (and I doubt you could do the correct probabilistic calculations controls for variance to be able to tell), but for things in which no one is known to have knowledge (theistic claims), it becomes an unknown probability. In the case of the poll of the audience, it can be more fairly said that their own opinions are not influencing others, but it can't be said of the more relevant examples.
There may be reasons why, I didn't say it was a "strong" case. Its an appeal to probability. The fact that 80% picked A increases the probability that A is the correct choice. Given no knowledge of other variables, that makes A more probably than B, C, or D. Maybe it isn't enough evidence for you to say the answer must be A or maybe you could learn more about the variables later. But it does provide evidence for A. Not sure how else to put it, its kinda obvious.
It's obviously and factually wrong, though. You just can't invent probabilities on a whim for unknowns like this. You have no indication that the beliefs of these individuals in any way corroborate to the truth. We have no way of evaluating the accuracy of these sorts of claims because we don't have a way to measure it. We're dealing with too many unknowns in an entirely unknown probability space.
If I ask the question: What is 5 >^< 8, where >^< is an unknown operator and the possible options are 13, 40, 9, and 3, and a majority of people pick 40, is 40 any more likely to be the answer? No! The operator stood for divide the second term by two and add to the first (9). For questions in which the probability of any relevant piece of information is unknown, the entire probability space becomes unknown. It just makes no sense to use this in any fashion.
