Probability: If the typical modern {person, LWer} knew all the positive and negative effects of taking {modafinil, piracetam, etc.} they would pay present prices to take them.
Confidence interval(s): If the typical LWer knew the extent of all effects of {cardiovascular, weight-training, other} exercise, and they were able to commit to any amount of said exercise and stick to it, how much would they do?
Assume that any time they spend doing exercise would otherwise have been spent doing other work.
If you want to be more specific, what advice would you give to healthy 25-year-olds, to healthy 40-year-olds, etc.?
What is the minimum effective period over which one should try a new dietary plan, before reaching conclusions on its effectiveness?
(In other words, what is the time granularity for dietary self-experimentation? This question could be generalized to other health issues where self-experimentation is appropriate.)
Probability: You are living in a simulation run by some sort of intelligence.
Probability: Other people exist independently of your own mind.
Probability: You are dreaming at this very moment. (Learning to dream lucidly is largely a matter of giving this a high probability and keeping it in mind, and updating on it when you encounter, for instance, people asking whether you're dreaming.)
Let G be a a grad student with an IQ of 130 and a background in logic/math/computing.
Probability: The quality of life of G will improve substantially as a consequence of reading the sequences.
Probability: Reading the sequences is a sound investment for G (compared to other activities)
Probability: If every person on the planet were trained in rationality (as far as IQ permits) humanity would allocate resources in a sane manner.
What's the probability that the Swiss central bank will maintain its cap on the franc vs. euro? And what is your confidence interval for when they might give it up if they do decide to give it up.
I have a question about Pascal's mugging. This does break the standard question-answer format, but you said not to be squeamish about that, so here goes the problem I am currently considering.
According to the wiki, the Standard Pascal's mugging is formulated like this:
Now suppose someone comes to me and says:
"Give me five dollars, or I'll use my magic powers from outside the Matrix to run a Turing machine that simulates and kills 3^^^^3 people."
Now, further suppose that someone says
..."Never give into a Pascal's Mugging except this one. I
What is the probability that a person who signs up for cryonics will be revived?
(Yes, I did already ask this, but my estimate is far enough from the apparent consensus here that I'd like to see more estimates)
I read once 15 years ago that when a child is born in a modern-day forager group, e.g., in the Amazon with a missing limb, he or she almost always dies because the tribe ostracizes the child unless there are anthropologists or other such visitors to bring the child to 'civilization'.
The OP instructs me to ask for the probability, but I am actually more interested in short descriptions of pieces of evidence that would move the probability by a factor of >3 or <.333 and how independent that piece of evidence is from all the other piece of evidence.
In s...
They are clearly able to maintain the cap for as long as they choose to. This is because the Swiss central bank has the ability to print Swiss francs. They can always make more, and use them to buy Euros. In fact, the phrase 'print' is misleading, as no paper is needed - only electronic money is created.
By this means, the swiss central bank is always able to lower the value of the Swiss franc - it can just carry on printing more until everyone who wants one for the price of 1 Euro 20 cents has one. It is impossible for speculators to buy more Swiss Francs than the bank is able to print.
The strategy seems risk free - if in the future the value of the Swiss franc ever falls against the Euro, they can reverse the process, selling all the Euros they bought earlier with Francs, and buying back their francs at their lower price, and deprinting them. After the deal is fully unwound, they should even have money left over due to the fact that they sold Francs at a higher price than they bought them back.
However, it is not. If the Euro itself were to run into trouble, and become increasingly worthless, the Swiss bank would find that its cap becomes a dead weight - as all the Euros that it bought with printed money become worthless, it will still have lots of outstanding Swiss francs, which will probably be dragged down and become worth much less themselves.
To avoid this problem, they should avoid actually buying Euros. This is done by loudly announcing their strategy of printing Swiss Francs as necessary. Since it's mathematically impossible for speculators to win by buying more Swiss Francs than the bank can print, hopefully no speculator will try, and then hopefully the bank won't actually have to buy all that many Euros after all. This should make it much less painful to abandon the cap if the Euro falls to pieces, and the Swiss want the Swiss franc to be worth much more than 1.2 Euros after all.
Whoa, a piece of financial advice that I can actually see the reasoning behind.
Often, there are questions you want to know the answers to. You want other people's opinions, because knowing the answer isn't worth the time you'd have to spend to find it, or you're unsure whether your answer is right.
LW seems like a good place to ask these questions because the people here are pretty rational. So, in this thread: You post a top-level comment with some question. Other people reply to your comment with their answers. You upvote answers that you agree with and questions whose answers you'd like to know.
A few (mostly obvious) guidelines:

For answers:
This thread is primarily for getting the hivemind's opinions on things, not for debating probabilities of propositions. Debating is also okay, though, especially since it will help question-posters to make up their minds.
Don't be too squeamish about breaking the question-answer format.
This is a followup to my comment in the open thread.
