The thread itself is immortal.
We've been wrong all along.
Jabba isn't trying to prove immortality. He's trying to create it.
The thread itself is immortal.
A pillar fallacy in Jabba's argument is, again relying on the fair die, that a probabilistic argument stating how improbable it is for a die to have rolled the number that came up doesn't dispute the fact of the face that's showing on the die.
That's not quite the fallacy.
I agree; your formulation is better.
Thank you. I'm glad we were able to come to agreement. That is something quite rare on the Internet.
- I'm thinkin again.
- The real issue, I think, is whether or not the event needs to be singled out/targeted ahead of time in order for its likelihood to be appropriately placed in the Bayesian formula. I claim that it is appropriate to place that likelihood into the Bayesian formula if we have a reasonably possible alternative hypothesis in which, this particular event is more likely than it is, given the original hypothesis.
- The issue now becomes – how/why would a reasonably possible hypothesis change things? I’m certainly not sure at this point -- but I'm thinking that it makes any occurrence of the event to be special...
- Say that we have two hypotheses: A and ~A.
- P(A) = .60.
- P(~A) = .40.
- P(E|A) = 1/1080.
- P(E|~A) = .62.
- Say that E occurs, and you now have to bet the farm on either A or ~A.
- Wouldn’t you have to bet your farm on ~A?
- If you say "no," and can explain it to me, that could go a long way towards cooling my ardor.
You have to define event E, and its probability under both hypotheses before it occurs, otherwise you are committing the Texas Sharpshooter fallacy.- I'm thinkin again.

JABBA: I think I can prove that I've won the lottery.
LOTTERYCO: OK, let's see your ticket.
JABBA: This week's winning numbers are 7, 15, 26, 28, 38, & 44. Under the hypothesis that I didn't win, this is so unlikely that it is virtually impossible. Look, here's a Bayesian formula showing that it if those numbers have come up, the hypothesis that I haven't won is infinitely unlikely to be correct. Since there is a reasonable possibility that I have won, the hypothesis that I have won is therefore infinitely more likely to be correct than the hypothesis that I haven't won, so I must have won.
LOTTERYCO: Hang on, it only shows that the hypothesis that you haven't won must be incorrect because you have put the likelihood of those numbers coming up as one over infinity. It isn't, it's just very unlikely.
JABBA: As I said, the likelihood of those numbers coming up is infinitesimal, because there are an infinite number of possible combinations.
LOTTERYCO: No, there are a finite number of possible combinations.
JABBA: What if Cleopatra had bought a ticket?
LOTTERYCO: That wouldn't change the fact that there are only a finite number of possibilities.
JABBA: my formula shows that it is impossible for me to have not won.
LOTTERYCO: No, it doesn't. Your argument relies on a false dilemma because it is merely trying to disprove one particular alternative to you winning, and the Texas sharpshooter fallacy because that combination of numbers is no more or less likely than any other combination. it isn't special.
JABBA: It doesn't need to be special because we have an alternative hypotheses under which that result is more likely.
LOTTERYCO: No we don't. The result is just as unlikely if you have won. Your winning would also require you to have bought a ticket with those numbers on it. Do you have that ticket?
JABBA: My formula shows that is impossible for me to have not won.
LOTTERYCO: Only because you have begged the question by claiming that the result is impossible if you haven't won. It isn't; it is entirely consistent with you not winning.
JABBA: But it is so unlikely that it is virtually impossible.
LOTTERYCO: No, it is possible, because there are a finite number of possible outcomes.
JABBA: If it is reasonably possible that I have won, then I must have won because the formula shows that it is impossible for me to have not won.
LOTTERYCO: No, it doesn't, for reasons the have already been provided. The only thing that matters here is whether you bought the winning ticket.
JABBA: The issue now is whether it matters that the result is no more or less likely than any other possible result if there is a reasonably possible alternative hypothesis to me not winning.
LOTTERYCO: Stop messing about and show us your ticket.
JABBA: This week's winning numbers are 7, 15, 26, 28, 38, & 44. Under the hypothesis that I didn't win, this is so unlikely that it is virtually impossible. Look, here's a Bayesian formula showing that it if those numbers have come up, the hypothesis that I haven't won is infinitely unlikely to be correct. Since there is a reasonable possibility that I have won, the hypothesis that I have won is therefore infinitely more likely to be correct than the hypothesis that I haven't won, so I must have won...
LOTTERYCO: Someone call security.
The next day:
JABBA: I can only deal with one point at a time, so I'll start by demonstrating that my assessment of the likelihood of those numbers coming up is correct.
But I think you would rather discuss the possibility of Cleopatra buying a ticket, so I'll start with that.
I'll be back.

LOTTERYCO: Security!
Jabba, if you convince yourself that you have an immortal soul, then what? Think you'll die happy?
You'd bet your farm on A?
