I'm not getting the same result... let's see if I have this right.
If you quit if the first coin is heads: 50%*75% death rate from quitting on heads, 50%*50% death rate from tails
If you never quit: 50% death rate from eventually getting tails (minus epsilon from branches where you never get tails)
These deathrates are fixed rather than a distribution, so switching to a logarithm isn't going to change which of them is larger.
I don't think the formula you link to is appropriate for this problem... it's dominated by the log(2^-n) factor, which fails to account ...
In every case of the pirates game, the decision-maker assigns one coin to every pirate an even number of steps away from himself, and the rest of the coins to himself (with more gold than pirates, anyway; things can get weird with large numbers of pirates). See the Wikipedia article Kawoomba linked to for an explanation of why.
I'm trying to interpret this in a way that makes it true, but I can't make "AI researchers" a well-defined set in that case. There are plenty of people working on AI who aren't capable of creating a strong AI, but it's hard to know in advance exactly which few researchers are the exception.
I don't think we know yet which people will need to cooperate for FAI to succeed.
[I've written two different responses to your comment. This one is more true to my state of mind when I wrote the comment you replied to.]
Consider this: a man gets a woman pregnant, the man leaves. The woman carries the child to birth, hands it over to an adoption agency. Raising the child to maturity is now someone else's problem, but it has those parents' genes. I do not want this to be a viable strategy. If some people choose this strategy, that only makes it more important to stop letting them cheat.
It's a lot of resources from the perspective of a single person, but I was thinking at a slightly larger scale. By "easy", I mean that manageable groups of people can do it repeatedly and be confident of success. Really, the fact that sentient minds can be valued in terms of resources at all is sufficient for my argument. (That value can then be ignored when assessing productivity, as it's a sunk cost.)
You seem to be looking in the wrong place with your "that people ought to earn every resource themselves" example - my opinion is tha...
This looks like equivocation between the math-like structure of the universe and mathematics itself - mathematics proper is something invented by humans, which happens to resemble the structure of the universe. Whatever is outside the universe is unknown, but probably can be discovered with considerable difficulty (and will probably be describable by mathematics, but will not be mathematics itself).
Do we know that saying "I don't know" is a failure? Clearly accepting the one-sixth answer given by the guide would be a failure, and stubbornly sticking to a different wrong answer is probably a failure as well, but saying "I need more time and equipment to figure this out" might very well be tolerated.
I thought of the possibility that Brennan might be counted as one of the people in the room (and thus he has more information than was stated) as a possible reason the one-sixth answer could be correct. From that angle, whether the information given describes the current moment is a very relevant concern.
After doing the math, it works out that if there are exactly 80 people in the room, and Brennar himself belongs to the Heresy of Virtue (highly unlikely), then one-sixth is in fact the correct estimation (based on 45 female virtuists, and 9 male virtuists other than Brennar).
At least in some cases, yes. I don't agree with the "every sentient mind has value" view that's so common around here; sentient minds are remarkably easy to create, using the reproduction method. Dividing a share of resources to every human according to their needs rewards producing as many children of possible, and not caring if they're a net drain on resources. I would prefer to reward a K-selection strategy, rather than an r-selection strategy.
The various advantages you list aren't simply a matter of chance; they're things I have because my parents earned the right to have children who live.
One method to check if you're dreaming is to hold your nose shut and try to breathe through it - if you're dreaming, your nose will work "normally", whereas if you're awake actual physics will take effect. (Note: every time I've done this while dreaming, I immediately got very excited and woke up.)
In my experience, the english "and" can also be interpreted as separating two statements that should be evaluated (and given credit for being right/wrong) separately. Under that interpretation, someone who says "A and B" where A is true and B is false is considered half-right, which is better than just saying "B" and being entirely wrong.
Though, looking back at the original question, it doesn't appear to use the word "and", so problems with that word specifically aren't very relevant to this article.
You need *at least* 26.9 bits. Since the boxes he talked about provide 2 bits each, you need 14 boxes to get *at least* 26.9 bits (13 boxes would only be 26 bits, not enough). 14 boxes happens to be 28 bits.
