This is my main question. I've never seen anything to imply that multi-day workshops are effective methods of learning. Going further, I'm not sure how Less Wrong supports Spaced Repetition and Distributed Practice on one hand, while also supporting an organization that's primary outreach seems to be crash courses. It's like Less Wrong is showing a forum wide cognitive dissonance that nobody notices.

That leaves a few options:

  • I'm wrong (though I consider it highly unlikely)
  • CFAR never bothered to look it up or uses self selection to convince themselves it's effective
  • CFAR is trying to optimize for something aside from spreading rationality, but they aren't actually saying what.

See my reply above. It is worth noting also that there is follow-up after the workshop (emails, group Skype calls, 1-on-1 follow-up sessions, and accountability buddies), and that the workshops are for many an entry-point into the alumni community and a longer-term community of practice (with many participating in the google group; attending our weekly alumni dojo; attending yearly alumni reunions and occasional advanced workshops, etc.). (Even so, our methodology if not what I would pick if our goal was to help participants memorize rote facts. But for ways of thinking, it seems to work better than anything else we've found. So far.)

I didn't mean to imply nonlinear functions are bad. It's just how humans are.

Picking gambles 1A and 2B, on the other hand, cannot be described by any utility function.

Prospect Theory describes this and even has a post here on lesswrong. My understanding is that humans have both a non-linear utility function as well as a non-linear risk function. This seems like a useful safeguard against imperfect risk estimation.

Insurance makes a profit in expectation, but an insurance salesman does have some tiny chance of bankruptcy, though I agree that this is not important. What is important, however, is that an insurance buyer is not guaranteed a loss, which is what distinguishes it from other Dutch books for me. Prospect theory and similar ideas are close to an explanation of why the Allais Paradox occurs. (That is, why humans pick gambles 1A and 2B, even though this is inconsistent.) But, to my knowledge, while utility theory is both a (bad) model of humans and a guide to how decisions should be made, prospect theory is a better model of humans but often describes errors in reasoning. (That is, I'm sure it prevents people from doing really stupid things in some cases. But for small bets, it's probably a bad idea; Kahneman suggests teaching yourself out of it by making yourself think ahead to how many such bets you'll make over a lifetime. This is a frame of mind in which the risk thing is less of a factor.)

The point of the Allais paradox is less about how humans violate the axiom of independence and more about how our utility functions are nonlinear, especially with respect to infinitesimal risk.

There is an existing Dutch Book for eliminating infinitesimal risk, and it's called insurance.

7Kindly
Yyyyes and no. Our utility functions are nonlinear, especially with respect to infinitesimal risk, but this is not inherently bad. There's no reason for our utility to be everywhere linear with wealth: in fact, it would be very strange for someone to equally value "Having $1 million" and "Having $2 million with 50% probability, and having no money at all (and starving on the street) otherwise". Insurance does take advantage of this, and it's weird in that both the insurance salesman and the buyers of insurance end up better off in expected utility, but it's not a Dutch Book in the usual sense: it doesn't guarantee either side a profit. The Allais paradox points out that people are not only averse to risk, but also inconsistent about how they are averse about it. The utility function U(X cents) = X is not risk-averse, and it picks gambles 1A and 2A (in Wikipedia's notation). The utility function U(X cents) = log X is extremely risk-averse, and it picks gambles 1B and 2B. Picking gambles 1A and 2B, on the other hand, cannot be described by any utility function. There's a Dutch book for the Allais paradox in this post reading after "money pump".

You may be interested in the term 'inverted classroom', if you're not already aware of it.

The basic idea is that it's the normal school system you grew up with, except students watch video lectures as homework, then do all work in class while they've got an expert there to help. Also, the time when the student is stuck in one place and forced to focus is when they're actually doing the hard stuff.

There's so many reasons why it's better than traditional education. I just hope inverted classrooms start to catch on sooner rather than later.

Anecdotally someone close to me did one of those and it was a quick way to burn thousands of dollars.

I tried to dissuade them, but end the end they came back with less knowledge than I did of the subject, and all I did was follow some youtube tutorials and look at stack overflow to create a couple learning apps for android.

That assumes the goal of App Academy is building knowledge. I don't think it is. The goal is getting a well paying job. Somnicule is likely smart and has knowledge of programming but he still doesn't know how to get a job despite not having formal credentials. Paying thousands of dollar for going to a state without a job to a state with a 50000k job is okay.

Anecdotally two people close to me did similar crash camps on coding and ended up with high-paying coding jobs despite having no experience in software development and degrees in unrelated fields. They seemed to do well, but since this isn't a controlled experiment I can't say whether the jobs they got are jobs they'd have not been able to get if they just studied on their own for a while.
1somnicule
The general incentives for this one seem better than average, (they generally take a cut of your first year's income rather than an upfront fee, high average income aster etc.) but I get a different, fixed payment contract since I'm from NZ. It's tempting, but higher risk than if I were from the US, especially since without a completed bachelors it'd be much harder to get a visa, and work here or in Australia won't pay nearly as well. I'm really losing motivation at university and have my own mental health issues, so the prospect of something like that has been somewhat comforting as an escape route. This has turned into "somnicule's personal problems" rather than the actual point of the thread, so I'll leave it there.

There should always, really, be "allowance in the original problem". Perhaps not explicitly factored in, but you should assign some nonzero probability to possibilities like "the experimenter lied to me", "I goofed in some crazy way", "I am being deceived by malevolent demons", etc. In practice, these wacky hypotheses may not occur to you until the evidence for them starts getting large, and you can decide at that point what prior probabilities you should have put on them. (Unfortunately it's easy to do that wrongly, e.g. because of hindsight bias.) As Douglas_Knight says, frequentist statistics is full of tests that will tell you when some otherwise plausible hypothesis (e.g., "these two samples are drawn from things with the same probability distribution") are incompatible with the data in particular (or not-so-particular) ways.
0Douglas_Knight
Frequentist tests are good here.

Surely that can't be correct.

Intuitively, I would be pretty ready to bet that I know the correct bookbag if I pulled out 5 red chips and 1 blue. 97% seems a fine level of confidence.

But if we get 1,000,004 red and 1,000,000 blues, I doubt I'd be so sure. It seems pretty obvious to me that you should be somewhere close to 50/50 because you're clearly getting random data. To say that you could be 97% confident is insane.

I concede that you're getting screwed over by the multi-verse at that point, but there's got to be some accounting for ratio. There is no way that you should be equally confident in your guess regardless of if you receive ratios of 5:1, 10:6, 104:100, or 1000004:1000000.

2Emile
Yeah, that's why I added "(in that context)" - i.e. we are 100% sure that those two hypotheses are the only one. If there's even a 0.01% chance that the distribution could be 50% / 50% (as is likely in the real world), then that hypothesis is going to become way more likely.
2othercriteria
There's actually some really cool math developed about situations like this one. Large deviation theory describes how occurrences like the 1,000,004 red / 1,000,000 blues one become unlikely at an exponential rate and how, conditioning on them occurring, information about the manner in which they occurred can be deduced. It's a sort of trivial conclusion in this case, but if we accept a principle of maximum entropy, we can be dead certain that any of the 2,000,004 red or blue draws looks marginally like a Bernoulli with 1,000,004:1,000,000 odds. That's just the likeliest way (outside of our setup being mistaken) of observing our extremely unlikely outcome.
gjm180

What getting a ratio of 1000004:1000000 tells you is that you're looking at the wrong hypotheses.

If you know absolutely-for-sure (because God told you, and God never lies) that you have either a (700,300) bag or a (300,700) bag and are sampling whichever bag it is uniformly and independently, and the only question is which of those two situations you're in, then the evidence does indeed favour the (700,300) bag by the same amount as it would if your draws were (8,4) instead of (1000004,1000000).

Dumb reinforcement question: How do I reward the successful partial-completion of an open ended task without reinforcing myself for quitting?

Basically I'm picking up the practice of using chocolates as reinforcement. I reward myself when I start and when I finish. This normally works very well. Start doing dishes -> chocolate -> do dishes -> finish doing dishes -> chocolate. It seems viable for anything with discrete end states.

Why does it need to be a hidden random timer? Reward yourself if you stayed on task for the past 30 minutes. (Hmm, I think we've just reinvented the Pomodoro Technique.)

Incidentally, have you (or others who use schemes like this) considered using intermittent reinforcement? Like, instead of just rewarding yourself upon meeting the victory condition, you flip a coin to see if you get the reward. It seems the obvious thing to do if you're going for the whole inner pigeon thing.

Otherwise Quirrel would be tracking down Phoenixes and... showing them the first 5 minutes of 'Up' or something.

Yes. "Up" was a fairly good movie, but it doesn't hold a candle to the short film that constituted its first 5 or 10 minutes. That should have won an Oscar.

I normally understand the LW use of 'taboo'.

It's just that 'taboo sex' brings up its own meaning/mental image faster.

I'm similarly peeved by words used with non-literal meanings in contexts that prime the literal meaning.

"Taboo 'sex'" might want to be rephrased though.

Until I saw Luke's response I thought it meant "Yes", "No", and "Yes, and it was really kinky sex!"

Yes. Better not use LW-specific lingo in a survey intended for lurkers as well as contributors. (I was going to change it but forgot to; done now.)

"Voting in primaries" is US specific, but it is significantly stronger than "voting in other elections." We have an order of magnitude more people voting in state elections than in primaries.

In fact, it's probably the strongest thing that you can do to influence politics in America. It's significantly rarer than volunteering to help elect parties or writing letters to your senator, and everyone who's at a primary already does those things.

5Nornagest
I only bothered looking up the statistics for California, but there I found 31% of registered voters showing up for the 2012 presidential primary elections, as opposed to 75% for the general election. (The statistics for eligible voters are somewhat lower, but more or less proportionally so.) That's a significant difference, but we're not talking an order of magnitude, and I'd be very surprised to find that that many people are politically engaged in more substantive ways.

Everyone does research before voting according to them.

My family members aren't familiar with even the most basic differences between the executive and legislative branches, and routinely make mistakes that would be cleared up with a 1st year understanding of government. They attribute blame/praise to one branch that they couldn't possibly be responsible due to how the separation of powers works.

But they've all "done their research, and [they] know a lot better than [I] do about who to vote for."

raising the minimum wage makes lower-productivity workers permanently unemployable, because their work is not worth the price, so no one can afford to hire them any more.

Employment is a function of being "worth the price" as you put it. But "worth the price" is not a fixed point; it is a function of demand. If only a handful of people want to buy your product, adding another person for $5/hr may not be worth the price. If everyone in the world were willing and able to buy your product, then you'd hire even if you had to pay $50/... (read more)

1Izeinwinter
Reality disagrees. The higher the minimum wage in a given country, the higher the labor force participation, - Ie, the percentage of the total population working goes up as the sums offered for their labor increases. The effect you describe may be real, but if so it is extremely consistently swamped by the basic law of supply and demand. Offering more money for labor causes more people to work.
8pjeby
But that's precisely what doesn't happen, particularly in a commodity business. When the minimum wage is raised, McDonalds has to either raise their price (which reduces demand), or find a way to do more with fewer workers. While it's true that for some products and services, demand can increase when the price is raised, it is not true of most products and services, and it is definitely not the case for products and services which are produced by minimum-wage workers. If you're talking minimum-wage workers, you're probably talking about basic goods and services, where demand is price driven.\ This "wages go up then demand goes up which increases employment" concept only works if you leave out any specification of whose wages, whose demand, for which products, increasing whose employment. Not everybody is a minimum wage worker, so unless those workers buy more stuff in exact proportion to how many of them are employed at each company, it doesn't actually translate into revenues for the right companies not to go belly-up if they don't lay people off and find a way to make up the difference. In particular, the timing and proportionality of that increased demand is pretty important. In particular, note that if the people with raised minimum wages go out and buy stuff from companies that aren't using minimum wage workers, or if the companies using minimum wage workers raise prices to stay afloat, there is a net zero change in demand, except that now non-minimum-wage workers are worse off than they were before, in two ways. First, their positional value as premium workers has eroded, which affects demand for their services, and also their job satisfaction. (i.e. the closer a worker's pay is to minimum wage, the less satisfied they are with their pay, even if the reason for the change is that minimum wage was raised.) Second, they are worse off because of the prices that were raised, as long as they use at least some goods produced by minimum wage workers. In short,

Correct. My point is that the Blueprint has conflicting messages about male attraction. It says one thing explicitly and very different thing implicitly.

I hold that the implicit teachings more closely match reality.

The people who point this out would be asked "Where's the proof?"

And if they could produce some, everyone would believe. And if they couldn't produce any... well why should they believe it in the first place?

3BlindIdiotPoster
That's how the conversation goes if the Soul Evangelist is trying to convert non believer into a believer. All she has to do is point out the existence of ghosts, the veil in the departments of mysteries, or maybe the legends of the resurrection stone. Most people would take this as sufficient evidence. In the proposed scenario, she is faced with the much more difficult task of converting a believer-in-belief.

Your intuitions about evolution and my intuitions must be drastically different.

I can imagine no possible world where human bodies were attached to an immortal decision-making engine, on an evolutionary timescale, where human brain biology still looks practically indistinguishable from all other mammal brain biology and where human grief behavior still corresponds to other mammal grief behavior.

0MugaSofer
How about if we replace "immortal decision-making engine"with "extradimensional backup drive"?
5BlindIdiotPoster
My intuition was that since a hypothetical immortal soul doesn't pass on the owner's genes and therefore doesn't contribute to genetic fitness, it should have little if any direct influence on evolutionary incentives. It's true that an animal that somehow evolved a soul would look drastically different neurologically from a human, but we know empirically that wizards are mostly the same as muggles psychologically/neurologically, so it seems this doesn't happen to be the case. By the way, I agree with Draco's hypothesis that if souls do exist, muggles probably don't have them, since they don't seem to have gotten any other benefits from the magic patch. I don't consider myself a particularly competent practitioner of counterfactual evopsych, so if you do, and still disagree, I suppose I'll have to update my beliefs.

It's not Harry's observations; it's everybody's observations of the world. People don't act like souls exist. If Dumbledore really thought that people just go on to another great adventure when they die, he wouldn't have a bunch of pedestals of broken wands.

Nobody in HPMOR believes in souls or acts like they exist. That's why Harry can decisively conclude that they don't exist.

4RolfAndreassen
Well, ok, but it's also been shown many times that most of the HPMOR cast needs to take several ranks in Knowledge(What The Heck They're Talking About) just to approach the effectiveness of the average level-1 fighter. Harry should not be weighting either their beliefs or their aliefs very strongly as evidence in any direction.
2Velorien
Correction: it is Harry's observations of the general public of the wizarding world, which is far from the same thing. There are many possible worlds in which a number of powerful wizards know for a fact that souls exist, and live their lives accordingly, but which look exactly the same to Harry. In fact, it's rather probable that a world in which a minority of wizards are aware that souls really exist would look just like this one. Imagine what it's like to be a member of such a minority trying to spread the truth. "By the way, souls really exist." "I know - everyone believes in souls." "No, I mean it - souls actually, literally, exist. So you shouldn't be too sad when people die, because they're just going somewhere else. And you shouldn't be too sad about your baby being stillborn, because it'll have another chance at happiness in the afterlife. And depending on their circumstances, severely disabled people might be better off comitting suicide so they can move on to a healthy existence faster. And- hey, where are you going?" I'm not saying any of those are necessarily reasonable conclusions to draw from the existence of souls, but it makes the point. Trying to live like this will automatically put you at odds with the rest of society, who will at best treat you like a crazy minority religious sect. So most soul-aware wizards will probably keep it to themselves, resulting in a world where Harry will be unaware of them.
5BlindIdiotPoster
Even if souls exist and everyone knows this, evolution would probably still select for humans who feel grief after their loved ones die.

Yes I disagree. The blueprint covers that both sexes attraction is value based. Women's attraction is dynamic because man's value is dynamic; man's attraction is static because women's value is static (looks based). I'd argue that women's value is static because they don't know how to hold intrinsic value and project that value to others aside from with their looks, just as 90% of men don't know how to do so either.

Note that this is a claim by user:Xachariah. The Blueprint does not make this oversimplified claim. In fact, it contradicts it.
1fubarobfusco
I'm a straight, polyamorous, and financially successful man. And I say unto ye: Huh?!

The blueprint makes that distinction but it's wrong. Male attraction is isomorphic to female attraction. The blueprint simply doesn't look into what it takes to attract men, so it doesn't make any statements about male attraction other than the superficial.

Anecdotally, as I became more attractive to women I became more attractive to men too. Not in a gay way, they just wanted my approval more and listened more and wanted to be my friends more than before. I felt the same way about my PUA friends as well; I could tell that they were getting cooler and I just wanted to be around them more.

There's no doubt in my mind that the teachings work on men too.

0gothgirl420666
This is interesting to me, what do you mean by this statement? For example, the blueprint says that men's attraction is more or less binary and relatively fixed, while a woman's is a highly dynamic sliding scale. Would you disagree with this idea?

Yes. It's not exclusively about picking up women, and from what I can recall the vast majority is about becoming an attractive person in general. Even the stuff about attracting women should generalize to women/gay men attracting straight/gay men.

1gothgirl420666
I strongly disagree. I personally wouldn't recommend it to anyone other than a straight man. It is definitely not catering to anyone else. A huge theme is that men and women feel attraction in drastically different ways and therefore need to pursue different strategies, so I expect that the majority of the advice would not transfer. And even if parts of it did, I'm not sure how you would go about identifying those parts. Lots of the general social skills and life attitudes might transfer, but again, not all of it, and it's heavily tied in with the themes of attracting women. I would only watch it if you're looking for ways to spend your time and are interested in the subject of relationships / social dynamics.

Disagree about optimal nap length being 24 minutes for everyone.

No, the rock might crush his finger, or cause other problems, but it would push his hand out of the way, while with a ring, the center would close.

He's familiar with cryonics then, or at least the concept of suspended animation.

It was another good outside-the-box idea, but Harry told his brain to keep thinking...

The next line implies that he'd have used the plan if he didn't immediately think up a better one. Any plan he comes up with to save Hermione has to be at least as likely to succeed as cryonics.

Why are people here reacting like Hermione is perma-dead?

I get that they'd act that way on reddit, but people here actually believe and sign up for cryonics. Harry's got a whole team of Alcor cryonic specialists right in his wand. And if he can't manage the magic, Dumbledore can. Hermione's soul and magic may have exploded in an impressive lightshow, but her brain is still fully oxygenated and hasn't even begun to decompose.

Everything that makes her her is still doing fine.

(And on a meta level, Elizer knows that fictional examples are strong drivers of behavior. A fictional example of cryonics working would be big for cryonics adoption.)

Because the old ancient wizard has reason to believe souls exist, which means that while it's probably possible to keep Hermione's body functioning, there's "a burst of something... too vast to be understood" that's just gone missing. Mind, that doesn't stop someone from figuring out a way anyway. Harry certainly plans to. It just makes things significantly more difficult.

Harry's brain suggested that an obvious way to stop the Dementors from seeing Bellatrix was to make her stop existing, i.e., kill her. Harry congratulated his brain on thinking outside the box and told it to continue searching. Kill her and then bring her back, came the next suggestion. Use Frigideiro to cool Bellatrix down to the point where her brain activity stops, then warm her up afterward using Thermos, just like people who fall into very cold water can be successfully revived half-an-hour later without noticeable brain damage. Harry considered this

Bullshit.

Never use "I'm too good at something to win" or "I only lose because other people are so bad". Those sort of explanations are never true. Not ever.

I don't know if there's some kind of word for this fallacy (maybe a relative of the Dunning-Kruger effect), but if your mind ever uses it in the future then you need to give your logic center a curbstomp in the balls. This sort of logic is ego protection bullshit. Hearing this explanation is the number one indicator that a person will never improve in a skillset.

Something like them is true of me in this case. Obviously I don't think my case is normal. If I didn't have lots of experiences of successfully manipulating people (mostly in high school, when I didn't care deeply about ethics) then it would indeed be silly for "I'm just handicapping" to show up on my radar as a hypothesis. Still though Jonii's hypothesis has enough merit that it at least describes some people (e.g. myself), and I don't get the impression he was suggesting it as the default explanation, so the strong reaction to the post seems misplaced. Might I suggest that you seem to be treating this issue as a pet cause, and are thus getting overly emotional about it, at least rhetorically? Your message is more or less correct but you sound like a moral crusader.

That's a nice heuristic, but unfortunately, it's easy to come up with cases where this heuristic is wrong. Say, people want to play a game, I'll use chess for availability, not because it best exemplifies this problem. If you want to have a fun game of chess, ideally you'd hope you did have roughly equal matches. If 9 out of 10 players are pretty weak, just learning the rules, and want to play and have fun with it, you, the 10th player, a strong club player, being an outlier, cannot partake because you are too good(with chess, you could maybe try giving your queen to handicap yourself, or take time handicap, to make games more interesting, but generally I feel that sorta of tricks still make it less for fun for all parties) While there might be obvious reasons to suspect bias being at play, unless you want to ban ever discussing topics that might involve bias, the best way around it, that I know of, is to actually focus on the topic. Just stating "woah, you probably are biased if you think thoughts like this" is something I did take into consideration. I was still curious to hear LW thoughts on this topic. The actual topic, not on whether LW thinks it's a bias-inducing topic or not. If you want me to add some disclaimer for other people, I'm open to suggestions. I was going to include one myself, that was basically saying "Failing socially in a way described here would at best be very very weak evidence of you being socially gifted, intelligent, or whatever. Reasoning presented here is not peer-reviewed, and might as well contain errors". I did not, because I didn't want to add yet another shiny distraction from the actual point presented. I didn't think it would be needed, either.

I'm fairly certain that's not how you're supposed to develop a habit of gratitude. It's not about doublithinking yourself into believing you like things that you dislike; it's to help you notice more things you like.

I've been doing a gratitude journal. I write three short notes from the last day where I was thankful for something a person did (eg, saving me a brownie or something). Then I take the one that makes me happiest and write a 1 paragraph description of what occurred, how I felt, and such that writing the paragraph makes me relive the moment.... (read more)

Here's another way to do gratitude wrong: thinking about the good things turns into "this is what can be lost".

For 12% of people it makes blood pressure higher not worse. The presenter chooses the terms 'adverse' and 'worse' for his own purposes.

My girlfriend has chronic hypotension, and can easily faint or become dizzy when standing or if she doesn't have enough water. Anecdotally, regular exercise seems to help prevent that. It's hard to find numbers, but the closest thing to solid I could find is that 26% of people with diabetes (couldn't find general population) suffer from hypotension.

Here is the study cited. There are four health markers that were chosen to be analyzed for this analysis. Actual physical fitness (ie VO2 max, strength, body fat percentage) were not measured. In all but one of the examined studies, diet was not controlled for, and they specifically only included endurance exercise, when virtually every recommendation is to combine endurance and strength exercise. Claiming that this population doesn't respond to exercise is a vast overstatement. More accurately, you might be able to say that "Endurance exercise alone isn't sufficient to improve health markers in a small fraction of the population." EDIT: The inverse to that is "Endurance exercise alone is sufficient to improve health markers in most of the population," which doesn't strike me as a good reason to not prescribe it.

This seems very interesting, and it's really cool that you've already been working on it. To clarify, you said you don't eat or drink anything unless it's a reward. Does this mean halting all meals?

How do you manage to eat healthily if all food has to stay within arm's reach? I suppose some fruits could stay out, but what about cooked meats or vegetables?

What do you do for recreation times: hanging out with others, visiting relatives, or just going to the beach or something, etc?

2D_Malik
Yes, stop all meals. You can get something a bit like a meal if you do a very high-value highly-rewarded task. Also, I let myself eat whatever I want for a few hours after doing something sufficiently awesome (such as accumulating sufficiently many CoZE points, or when I spent 3 hours coding up a system to implement another lifehack thing). My eating habits are a lot less healthy than they used to be - chips, fruit juice, candy, chocolate-chip cookies, etc., but also healthier things like nuts, popcorn, sandwiches and meat. If you do a high-value, highly-rewarded task, you can finish things quite quickly. At the moment I feel like health isn't as important as good reinforcement, but I'm planning to research that more. I don't do much social interaction (I don't value it highly terminally, and most of it is instrumentally useless) but have broken the system twice to eat lunch with people, and put it on hold for 3 days while away at a college's admit weekend.

Why do you advertise for Goodsearch? As far as I can tell, Goodsearch itself is a for-profit LLC that makes it's money by drawing referrals to Yahoo, by way of putting kittens and children on it's front page and making people feel good about doing searches. They're just trading a portion of revenue for increased marketshare.

But you're trading time. You earn 1 cent a search; at minimum wage, that's 5 seconds of labor time. Rough estimate of their criteria says that less than half my searches would be eligible for donation. So, in order for Goodsearch t... (read more)

I recommend Goodsearch because for me it was very helpful for getting me to search more. I don't particularly care what their business model is and in fact I hope they make good money so that I can continue benefiting from their service. While I certainly agree that Google search is typically better than Yahoo search, I find that in practice Yahoo search is good enough most of the time, Google search is still easily available via the URL bar, and conducting any search at all is better than not doing so. Even if Goodsearch makes using search less efficient, for me it makes me use search more often, and the efficiency lost by decreasing any given search seems more than made up for by the efficiency gained by searching at all in contexts where I might otherwise forget to. Your mileage may, of course, vary, but hey-- if things don't work it's easy to switch your default toolbar search engine back! This strikes me as a situation that is remarkably easy to test and potentially very valuable-- hence my recommendation.

The labeling isn't very confusing right now, but in 9 months it will be.

That's true. Adam is kindly updating videos with the correct year, and we'll reupload shortly. He's done excellent and professional work for the conference. As an FYI, the FHI's not planning to have a Winter Intelligence Conference in winter 2013, as we're pretty busy getting new projects off the ground. The expectation is that we'll continue having them at two year intervals for now (the previous WIC was in January 2011), although this isn't set in stone. This year's AGI conference will be in Beijing July 31- August 3 (last year's was hosted in Oxford as part of the WIC)

Woah. Instead of potato chips, I could be eating an equal amount of bacon.

I'm never going to eat another potato chip again.

2Desrtopa
Well, the fact that they have about the same calories per gram doesn't mean that they're equally healthy. The fat in bacon is almost all saturated. Bacon is probably more filling per calorie though, so you'd be less likely to gain weight snacking on bacon than potato chips.

Regarding whitespace, I usually like this style of spacing in articles. It makes it much easier to see what's going on and identify clusters of ideas.
It's like punctuation for paragraphs!

In this case, however, the whitespace seemed to have been placed at random and did not separate ideas.

Are you suggesting that rationality takes the same level of one-on-one contact that dancing does?

I'm sure it wouldn't be too much trouble to go out and find rationality partners, if that's what it took. I'd still need the curriculum though.

2Viliam_Bur
Talking with a rational person who disagrees with you can be a great experience, if both of you prefer finding the truth above winning the discussion. (I am not saying that the minicamps are about this. Just answering your question, out of context.)

I can see the usefulness of networking. Though I don't feel like I'm in the phase of my life where I'd want to go to such lengths just to network and have excellent conversations. I could imagine that being worthwhile enough to me one day.

It's good to hear about the followups. They mentioned that in the original post, but I didn't know how extensive it was. I suppose it's unfair to demand concrete data, when dealing with such small sample sizes.

Reference class tennis, but I did learn dancing via youtube + a partner. A couple of years of dance classes were pretty useless compared to how much I learned after a month of study online.

I bet that partner thing was kind of important.

I have a couple of questions:
1) Does the $3900 cost primarily cover the cost of the workshop itself, or is it mostly used as a revenue source for CFAR to keep the doors open year-round?

2) What advantages does the weekend retreat system offer that other systems don't, specifically distance learning?

3) Are there any plans to expand into distance learning, for example into the Khan Academy, edX, Udacity model?

Everything you've mentioned sounds great, but I'm inherently skeptical of a weekend retreat format. After all, even gay cure camps 'work' and have t... (read more)

1) There isn't that much of a pragmatic difference between whether the money is going to the workshop cost or to keep the CFAR doors open year round. CFAR needs to keep the doors open year round in order to continue to be able to host workshops and keep developing and refining curriculum. The venues and food are always great, but not $1000/night nice. 2) There's something about the weekend retreat format that allows for a really strongly transformative experience. Your time at a CFAR workshop somehow feels more significant than your time in everyday life, like each moment is just pulsing with more of the very fiber that gives reality its existence. This also results in some optimization for remembering self -- the moments at the CFAR workshop feel like something that will be remembered and deconstructed for far longer than the experience itself lasts. And there is a neat change towards increased emotional openness that happens over the course of spending such an intense weekend with new friends. Also, the kinds of people that attend $3900 weekend workshops can make for incredibly high value networking. 3) I expect it will happen eventually, sure.
7palladias
Re (1): The $3900 covers the cost of the workshop (the earliest workshops were offered at a loss to start testing the material). It covers cost of venue, outreach to find participants, and time spent on curriculum development and research to make sure the material offered is useful and clear.

2) What advantages does the weekend retreat system offer that other systems don't, specifically distance learning?

Most of the value that I got out of the January workshop was in having face-to-face contact with the instructors and the other students. This was enjoyable, impressed the units on me strongly, and led to many interesting, unplanned, and high-value conversations (e.g. one 5-minute conversation completely changed my attitude towards both nutrition and exercise, which I finally started paying attention to after the workshop).
