I get the feeling that there must be an "anthropic weirdness" literature out there that I don't know about. I don't know how else to explain why no one else is reacting to these paradoxes in the way that seems to me to be obvious. But perhaps my reaction would be quickly dismissed as naïve by those who have thought more about this.
The "obvious" reaction seems to me to be this:
The winner of the lottery, or Barack Obama for that matter, has no more evidence that he or she is in a holodeck than anyone else has.
Take the lottery winner. We all, including the winner, made the same observation. No one, including the winner, observed anything unusual. What we all saw was this: someone won the lottery that week. This is not an uncommon event. Someone wins the lottery in many weeks.
Perhaps people are confused because the winner will report this shared observation by saying
And, indeed, in that regard, the winner is unique. But, in the very way that I formulated this fact, the referent of "I" is defined to be the winner. Therefore, the above remark is logically equivalent to
That hardly seems the sort of surprising evidence that might lead one to suspect holodecks. Moreover, it's what we all observed. With regards to evidence for holodecks or what have you, the winner is not in a special position.
Maybe people think, "But the winner predicted what the numbers would be beforehand, and he or she then observed those predictions come true. That gives the winner strong evidence for the false conclusion that he or she can predict lotteries."
But that conclusion just doesn't follow. We all observed the same thing: Millions of people tried to guess the numbers, and one (or a few) got them right. That's all that any of us saw. The number of correct predictions that we all saw was perfectly consistent with chance.
If the winner were unaware of all the other people who tried to guess the numbers, then he or she would be in trouble. Then he or she might validly reason "Just one person tried to guess the numbers, and that person got it right. Therefore, that person must have a special ability to predict the numbers." That's the person I pity, someone who had the misfortune to be exposed to extremely misleading observations. But normal lottery winners are not in that position.
I also don't see the asymmetry in the Quantum Theory of Immortality scenario. You and your friend both make the same observation: the version of you in the Everett branch where the gun doesn't go off doesn't get shot. Assuming that you both believe Many-Worlds, you both know that there are scads of branches out there where both your friend and your bullet-punctured remains "observed" (i.e., recorded in their physical structure), the gun's firing. And if you weren't convinced of Many-Worlds, then you will likely conclude that your model of physics is wrong because of the high probability that it assigned to the gun's firing. Rather than conclude that Many-Worlds is true, you will probably throw out QM altogether. (You might do this eventually even if you did go in believing Many-Worlds.) But, again, you have no privileged position over your friend here, because you don't see anything that he doesn't see.
Am I missing something? Are these paradoxes really this easy to dismiss?
The idea of a holodeck is that it's a simulated reality centred around you. In fact, many, most, or all of the simulated people in the holodeck may not be conscious observers at all.
So, either I am one of 6 billion conscious people on Earth, or I am the centre of some relatively tiny simulation. Winning the lottery seems like evidence for the latter, because if I am in a holodeck, interesting things are more likely to happen to me.
As you say, when someone wins the lottery, all 6 billion people on Earth get the same information. But that's assuming they're real in the first place, and so seems to beg the question.
In passing, I said:
And lo, CronoDAS said:
To which I replied:
There's a certain resemblance here - though not an actual analogy - to the strange position your friend ends up in, after you test the Quantum Theory of Immortality.
For those unfamiliar with QTI, it's a simple simultaneous test of many-worlds plus a particular interpretation of anthropic observer-selection effects: You put a gun to your head and wire up the trigger to a quantum coinflipper. After flipping a million coins, if the gun still hasn't gone off, you can be pretty sure of the simultaneous truth of MWI+QTI.
But what is your watching friend supposed to think? Though his predicament is perfectly predictable to you - that is, you expected before starting the experiment to see his confusion - from his perspective it is just a pure 100% unexplained miracle. What you have reason to believe and what he has reason to believe would now seem separated by an uncrossable gap, which no amount of explanation can bridge. This is the main plausible exception I know to Aumann's Agreement Theorem.
Pity those poor folk who actually win the lottery! If the hypothesis "this world is a holodeck" is normatively assigned a calibrated confidence well above 10-8, the lottery winner now has incommunicable good reason to believe they are in a holodeck. (I.e. to believe that the universe is such that most conscious observers observe ridiculously improbable positive events.)
It's a sad situation to be in - but don't worry: it will always happen to someone else, not you.
