The thing about that is, is that not everyone is donating at the same time, so that they can see the expected value change.

Yes, but there can be long delays between a donation happening and updates. Coordinating donations can be non-trivial, especially when flash crowds appear (e.g. sob story on reddit). Also, such a randomized approach is not necessary if one can just donate small amounts to multiple projects instead (i.e. if transaction fees are not a problem).

I don't know. The question of self is a hard one. I would not, because I would like my consciousness, as in the one that I control (a little recursive, but you get the point) to be alive, and because that other me is another distinct set of atoms, and therefore my neurons don't control him. So I would say no

There might not be such a thing as "distinct set of atoms" on fundamental level and even if it does, the atoms/molecules in constellation that constitutes you are turned over all the time. In short you in 5 sec do not consist of the same set of atoms at present you. Does that make you think that 5 sec you is not really you?

You're right, that was one of the erroneous assumptions I made. The problem with that is that there are an infinite number of permutations of possible universes. Even if only a small fraction of them are habitable, and a small fraction of those are conducive to intelligent life, we still have the multiplying by infinity issue. I don't know how valid using infinity in an equation is though, because when there are two infinities it breaks down. For example, if they're are an infinite amount of dogs in New York, and 10% of dogs are terriers, technically the probability of the next dog you see being a terrier is equal to that of any other dog. That again simply doesn't make sense to me

Random question that just occurred to me: would you be fine if an exact copy was made of you (ignore quantum mechanics for now), and the old you was killed off?

Could I come back at say 21 with the knowledge / wisdom I have now?

If you asked me afterwards, I'd hardly say "no".

Me? I suppose so - if I could be really convinced the process was reliable. Make two of me and I might need less convincing.

On your argument, there is little need to flawlessly compute the universe. If a civilization sees that their laws are inconsistent with their observations, then they will change their laws to reflect their observations. Because there is no way to conclusively prove your laws are correct, it is impossible for a simulation to state that "Our laws are correct, therefore there is a flaw in the universe". Furthermore, on the probability that our ancestors have obtained the computing power of running a simulation:

You seem to be assuming that we'd be simulated by a universe which is physically like our own. Our simulations, at least, are of much simpler scenarios than what we're living in. I'm not sure what properties a universe would need to have to make simulating our universe relatively cheap and easy. I'm guessing at smaller and faster fundamental particles.

That's really interesting; maybe we need a new name for the (convoluted) modern Socratic method?

That's why I think that the basic concept of "building block" schooling works-you essentially keep the distance constant, but teach them ever more challenging topics. The one time where there is a large gap is in the introduction of completely new ideas or subjects. For example, in physics when people first learn of general relativity there is a large inferential distance, which is very hard to remedy.

Amount you need to understand to get from what you currently understand to also understanding the new thing. Eliezer talks about it in a piece well worth reading.

Interestingly, the one time that I find that the modern Socratic method works is math. Because it is so much more helpful in math to have an innate understanding of the subjects, you have to be able to explain why an equation or theorem works/is true. So when time permits, guiding them with questions is very helpful, as figuring something out sticks in your mind more than having it on a board.

You're right, I really wasn't thinking of a specific method of comparison, rather I was just kind of ranting on how much I dislike it. Of the teaching methods we have: Lecturing- Above average students might be bored if the teacher is telling them information they already knew, but it many times has just a blanket boredom effect

Demonstrating- Even if certain students already know information, can still be interesting if they try to extend their thinking on the demonstration. The opposite of a lecture, many times has a blanket engaging effect

Socratic- See ... (read more)

Well, there is of course the alternative of getting away from the idea of one-teacher-many-students altogether, by encouraging students to teach one another, or by creating autodidactic tools that students can explore on their own, or by segmenting students differently, etc. But yeah, if we're restricting the scope of discussion to traditional teacher-led classrooms, the segmentation problem is hard to get away from. That said, I'm rather fond of Socratic inquiry myself.

On the Socratic method; I was wondering if anyone had any ideas about that or could write an article on the benefits and consequences of it. From what I see is that the above average students get frustrated when the jump to conclusions faster than the teachers guide the class to them, and the below average students who consistently aren't understanding the questions, with the Socratic method really only working for the average students (this scale though can be re-calibrated, for example if the teacher caters the to the below average students, now the average students are also frustrated, and vice versa.)

The main problem with using the Socratic Method as a didactic tool is that it really wasn't intended for that purpose; Socrates was a man who claimed to know nothing, and the "Socratic method" is simply a collection of techniques he developed to demonstrate that other people didn't know anything either. 90% of his so-called Method (as demonstrated in the early dialogues like Euthyphro or Charmides -- which have the highest probability of actually being representative of things he actually said, and not just mouthpiecing from Plato) consists of Socrates demanding that people define their terms, refusing to continue the argument until they did so, and then pointing out that the definitions they supply are either self-contradictory or inconsistent with what they're actually arguing. When used correctly, the Socratic method is great at exposing logical inconsistency and self- contradiction, but extremely inefficient when it comes to guiding people to truth -- its purpose is to destroy; it does not create.

I'm curious: are you comparing the Socratic method here to some other technique that works more reliably with a broad range of capabilities? I would have thought that no matter what technique I use, the subset of my class that I devote most of my attention to will get the most benefit, and everyone else will be frustrated that they aren't getting as much out of it as they could with more attention.

The issue with that line of thinking, while I think it is the optimal result, is that you have some degree of control over your future self, in setting up binding or non-binding systems for you to follow in the future. But you have no control over your past self, only your present and some control over your future. So now, you have to think of yourself as the soon to be past self, and your future self as your present self. That then goes against the authors original goal, because then you will be working forever, as the gratification is always in the future.

I find this is the most constructive way to resolve a debate between two people (see: http://lesswrong.com/lw/881/the_pleasures_of_rationality/) But in long-running debates, or ones with heated debaters, this is much harder. Firstly, because many debates are long running precisely because this strategy cannot be applied to the,. The issue with heated debaters is that this requires an open mindset of looking for truth versus looking to prove yourself right, which I find lacking in many debates.

What happens in that situation is that people continue to invest in malaria nets, so much that the marginal cost of saving another life goes from say, $500 to $700, and for $600 dollars you can dig a well, saving another persons life. In essence, you donate to the most efficient charity until that money has caused the charity to have to pay more to save lives, and therefore stops being the most efficient charity.

I've thought about this problem before, but in the context of peer peer-to-peer file sharing. The problem is that everyone is acting independent and with limited knowledge. It's hard to know what other people are choosing. There may also be long delays between you and others paying and the cost changing. Say that the optimal outcome is that out of $1000M, $200M is spent on insect nets and $800M on wells, and that you can only donate to one charity (too bothersome or high transaction costs or something). Now, if everyone is rational they are going to donate to the wells, and no one to nets. This is a suboptimal outcome. It'd also be difficult to coordinate the millions of people donating, so that just the right amount choose nets instead of wells. A solution to such coordination is to roll a dice. If everyone makes a random selection and lets the probability of choosing nets be 2/10ths then the expected outcome is just what we want. Now, you can adjust this to how many (you think) are playing like yourselves. E.g. if you know most people are going to give to wells, perhaps it'd be better if you put higher probability on nets (perhaps 100%).
