I see your point about the special snowflake. Toontown’s argument still doesn’t seem to make sense unless there is something different about the specific brain. If the point is that everyone with a brain seems to have won the lottery (odds wise) then it seems like Loss Leader’s point about running multiple lotteries every day for a few billion years comes into play. After all, it seems that once you start getting brains, it’s going to be somebody’s brain pretty much every time.
Toontown, I genuinely have been trying to follow your argument. If you can help me see where I’m missing it I really would be interested.
Sorry. Can't help you. I'm using a perspective you refuse to take.
You don't accept the validity of your subjective perspective, or mine, so there is no use talking about it. I just talk about it sometimes for practice, in a sense. Nothing will come of it.
Nor is there any simple analogy or math I can think of to clarify what I see as your categorization error when you lump yourself in with all the other brains and lose critical specific information in the bargain.
It isn't about being a "special snowflake". It is all about the fact that the lumping strategy loses information. The information loss is real, and I can explain the probabilistic side of it:
Probalistically, It is akin to trying to calculate your chance of winning the lottery by lumping yourself in with all other lottery players. All you can come up with is a near certainty that someone will win, and you are a someone, so there is a non-zero chance you will win. But that's very nearly meaningless. If you want to know what your specific chances are, you have to take the subjective perspective and calculate your individual odds. Or read the individual odds printed on the ticket. But those odds are relative to the narcissistic, verboten subjective perspective, so you will presumably become a thread heretic if you do so.
However, should you choose to become a thread heretic and look at the prior probability of someone winning the lottery versus the prior probability of you winning, you will see that those probabilities are nearly as different as they can get. Further thought will reveal that the two probabilities are derived from fundamentally different perspectives. Further thought will reveal that both perspectives, though fundamentally different, are equally valid. Further thought will reveal that "equally valid" and 'equally informative' are not equivalent. The subjectively derived probability gives you the useful information.
But even if you do heretically determine your individual chance of winning, you will still need to have a feel for probability to understand just how daunting a proposition it is for you specifically. You have to understand that those odds stacked against you are mountainous and real, they don't like you at all, and they are telling you they don't give a rat's ass about your pitiful little non-zero chance of winning. They are going to slap that out of your hand and make you eat it. Nothing at all like the near certainty that someone else will win. I can confidently predict that you won't be the someone else that wins. But some other someone else will. That's for sure.
I can tell you how the conversation might go if, for example, someone told me that the only reason eternal darkness has not prevailed is because my particular brain has come into existence.
I would reply, "But the prior odds against this particular brain coming into existence are giganogargantuan, and yet eternal darkness has not prevailed, as your hypothesis assures me it should have, with a giganogargantuanly high confidence. Therefore your hypothesis has failed miserably to account for my current sentient experience. If you are correct, then I shouldn't be here, now or ever. Someone, certainly, but not me. Not ever me. Effectively, that is what you're saying."
To which the claimant replies that no, that isn't what they're saying, perspective doesn't matter in probability, I have committed the Texas Sharpshooter fallacy, and besides I already exist, so it's too late to question my existence.
To which I would reply, "I see. You would have me believe perspective matters when you are condemning me to eternal darkness, but not when I point out that your condemnation has failed miserably. Nor have I committed any Texas Chainsaw Massacre. Nor am I questioning the absence of eternal darkness. On the contrary, I'm using the absence of eternal darkness to question your explanation of it's absence. I find myself starting to doubt you."
From all the above and much more, I conclude that perspective does matter in probability. There are those who trot blithely forward, secure in the knowledge that "perspective is irrelevant in probability", and thread bias has attracted a crew of them. And they can't even calculate their chance of winning a lottery without taking the perspective they say is irrelevant in probability.
