I wouldn't make the mistake of connecting Jabba's performance in this forum to any specific belief system, or to any desire to support one. While the authenticity of the Shroud of Turin is generally of interest only to Christians (and perhaps only to Catholics), Jabba did not profess or defend the Catholic faith in his effort to prove it was real. He said he was basically just interested in the "spiritual" and he had no special devotion to Catholicism or Christianity. And while Jabba's audience elsewhere tend to be Christian, I don't get that he's trying to argue immortality here from a strictly Christian perspective. (Or from a mathematical perspective either, for that matter, but here we are.) Therefore rebuttals saying that Jabba's argument is incompatible with some supposed religion probably miss the mark.
Of course we know from external sources that his probable goal here is nothing more noble than to rail against skeptics. And we glean from observation that he wants to be seen as a hero for doing so, which explains a lot of the debate dynamic. Jabba told us during the Shroud debate that skeptics were just being mean-spirited by rejecting his excellent evidence, and that a less "biased" audience received his arguments well. When asked to put up, he made the mistake of linking to an outside forum where Shroudie sycophants were happily stroking Jabba's ego for his efforts against skepticism. I think it's fair to suppose that's what he's after again.
What that would mean is that he's interested only in expending the least effort it would take to appeal to the segment of people who clamor for secular confirmation of religious belief. I've observed that segment tends to glom onto champions who turn out to be pseudo-intellectuals or pseudo-scientists of little, if any, distinction outside the scope of religious polemics.
Jabba has no prodigious aptitude for statistical math. That much is certain, and in his more candid moments he has admitted as much despite his ongoing claims elsewhere to be a "certified statistician." And his argument suffers greatly for that deficit, as has been pointed out. But his intended audience will not be statisticians or mathematicians. It is sufficient for Jabba's audience that his notation appears "mathy" enough to convince a layman it might mean something. Jabba appears uninterested in classical philosophy, over which he claims superiority. He shows no inclination to research reincarnation, animism, or any of the other schools of thought upon which he relies. He has left his conclusion sufficiently open-ended so that it
could appeal to rank and file Christians if only to say he has refuted materialism. But his intended audience will not be philosophers. He merely needs to talk as much pseudo-philosopy as it takes to impress a lay anti-skeptic audience. And Jabba shows no desire to defend or discuss the science he says supports his claim. There is no indication he even reads what he cites. Most of his "science" seems to come from heavy-on-woo popular books, which he seems to expect to simply be taken uncritically at face value. And that's okay for him, because none of his intended audience will be scientists. They just need to be told -- true or not -- that there is secular science that nurtures their beliefs, with citations that will certainly go unread or even unfollowed.
We are compelled by the ground rules to take Jabba at face value and examine only the mathematical, factual, and logical claims of his arguments. But Jabba is pretty
explicit about his inability to hold up his side of such a debate. He is utterly convinced he's right -- if right enough only to fool an undiscriminating audience -- and he doesn't want anything to get in the way of his applause.
