Natural experiments: I've been trying a new acne wash for the past 6 months, and although I felt like it was working, I wasn't sure. Then, the other day when I was applying it to my back, my partner noticed there was an area I wasn't reaching. In fact, there was an entire line on my back where I wasn't stretching enough to get the wash on. This line coincided exactly with a line of acne, while the rest of my back was clear.
Now I know the wash works for me.

Strong statement from Bill Gates on machine superintelligence as an x-risk, on today's Reddit AMA:
I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage it well. A few decades after that though the intelligence is strong enough to be a concern. I agree with Elon Musk and some others on this and don't understand why some people are not concerned.
Someone here mentioned the idea that making objects very cold was a more plausible source of unexpected physics leading to extinction than high energy physics because high energy events occur in the atmosphere all the time whereas there's no reason to expect any non-artificial cause of temperatures in the millKelvin range. Does someone have a source for this observation? I'm writing a post where I'd like to attribute this properly.
Sometimes when one learns something it makes many other things "click" by making them all make sense in a broader framework. Moreover, when this happens I will be astounded I hadn't learned about the thing in the first place. One very memorable such occasion is when I learned about categories and how many different mathematical structures could be thought of in that context. Do people have other examples where they have been "Wow. That makes so much sense. Why didn't anyone previously say that?"
Basic game theory: Nash equilibriums and the idea of evolutionary game theory.
An unbelievable number of human problems map onto the property that a particular Nash equilibrium or evolutionarily stable strategy isn't guaranteed to be socially desirable (or even Pareto-efficient, or even when compared only to other Nash equilibrium).
Likewise, you really can't do non-trivial consequentialist reasoning without accounting for the impact of your proposed strategy on the strategies of other agents.
Once you've seen the patterns, you can avoid painstakingly deriving or arguing for the general picture over and over again, which probably consumes about a third of all policy and ethics debate. And more critically, you can avoid missing the importance of interlocking strategies in cases where it does matter: Another third of public debate is reserved for wondering why people are acting in the way that the actions of other people encourage them to act; or for helpfully suggesting that some group should move unilaterally along a moral gradient, and then blindly assuming that this will lead to a happier equilibrium once everything adjusts.
1) The idea of constructing things out of axioms. This is probably old hat to everyone here, but I was clumsily groping towards how to describe a bunch of philosophical intuitions I had, and then I was learning math proofs and understood that any "universe" can be described in terms of a set of statements, and suddenly I understood what finally lay at the end of every chain of why?s and had the words to talk about a bunch of philosophical ideas...not to mention finally understanding what math is, why it's not mysterious if physics is counterintuitive, and so on. (Previously I had thought of "axioms" as"assumptions", rather than building blocks.). Afterwards, I felt a little cheated, because it is a concept much simpler than algebra and it ought to have been taught in grade school.
2) Something more specialized: I managed to get a B.S. in neuroscience without knowing about the thalamus. I mean, knew the word and I knew approximately where it was and what it did, but I did not know that it was the hub for everything. (By which I mean, nearly every connection is either cortico-cortico or cortico-thalamic). After graduation, I was involved in a project whe...
Basic chemistry. I hated chemistry the first 2-3 of years of high school (UK; I don't know if it's taught differently elsewhere). It was all about laundry lists of chemicals, their apparently random properties, and mixing them according to haphazard instructions with results that very occasionally corresponded approximately with what we were informed they should be. We were sort of shown the periodic table, of course, but not really enlightened as to what it all meant. I found it boring and pointless. I hated memorising the properties and relationships of the chemicals we were supposed to know about.
Then, all of a sudden (I think right at the start of year 10), they told us about electron shells. There was rhyme! There was reason! There were underlying, and actually rather enthralling and beautiful, explanations! The periodic table made SO MUCH SENSE. It was too late for me... I had already pretty much solidified in my dislike of chemistry, and had decided not to take an excessive amount of science at GCSE because similar (though less obvious) things had happened in biology and physics, too. But at least I did get that small set of revelations. Why on earth they didn't explain it to us like that right from the start, I have no idea. I would have loved it.
I seem to recall that some Democrat and Republican donors have agreed not to give to their respective parties, but rather to charity, on the condition that their opponents do the same. Does anyone know about this? Mine and Google's combined efforts have been fruitless. Seems a very nice idea that could be used much more widely to re-distribute resources away from zero-sum games to games with joint interests.
I remember somewhere in the sequences EY mentioned that Bayesianism was a more general method of which the scientific method was merely a special case. Now I find this, Dempster-Shafer theory, which according to Wikipedia is an even more general method, of which Bayesianism is merely a special case.
Has this topic been given any treatment here?
On Sunday at 11 AM Eastern and 8 AM Pacific*, I will be playing a round of AI Box with a person who wishes to remain anonymous. I will be playing as AI, and my opponent will be playing as Gatekeeper (GK). The loser will pay the winner $25, and will also donate $25 to the winner's charity of choice. The outcome will be posted here, and maybe a write-up if the game was interesting. We will be using Tuxedage's ruleset with two clarifications:
The transcript will not be made public, sorry. We are looking for a neutral third party who will agree beforehand to read and verify the transcript. Preferably someone who has already played in many games, who will not have their experience ruined by reading someone else's transcript.
I've been using LyX for preparing my doctoral dissertation and I'm amazed that such a complete and capable tool isn't more widely known and used. I can't imagine preparing scientific documents now with anything other than LyX, and I can't imagine that I used to use software like MS Word for this purpose. Anyone have any other examples of obscure but amazingly capable software?
Are there any updates on when the Sequences e-book versions are going to be released? I'm planning a reread of some of the core material and might wait if the release is imminent.
In the spirit of admitting when I am wrong, I would like to say that when /u/Azathoth123/ said that schools were encouraging children to be gay and transsexual, I thought he was being paranoid. I thought that schools were preaching tolerance, and this had been misinterpreted.
Also, the strategy of asking children whether any of their friends are trans is bizarre, because (a) if about 0.1% of adults are trans, then you really wouldn't expect any children to be trans unless the population of the school is gigantic, regardless of the school's attitude to tolerance and (b) children should not be discussing their friend's private secrets with strangers.
I have nothing against transexuals, and in fact they seem like obvious allies of transhumanists. But, unlike homosexuality, 'being trapped in the wrong body' clearly causes a lot of psychological distress - otherwise people wouldn't undergo serious surgery to correct it (although this is not necessarly true of people who don't identify as either gender). As long as there is a possibility that it has partially psychological roots (apparently twin studies show 62% heritability), priming people at a young age (1...
While it is good to acknowledge when one is wrong, this is hardly strong evidence. One has one school in one location making an allegation. There also seems to be a big leap between asking people if they know anyone trapped and pushing people to be gay or transsexual. (I agree though with your points in your second paragraph.)
I suppose that this is only an allegation at the moment, although other similar allegations about the same organisation pushing a left-wing agenda at the expense of education have been made, which makes the whole thing more plausible (plus there is Azathoth's original allegation).
Asking an adult if they know anyone who is trapped is ok. The problem is that asking a 10 year old primes them with a concept they would not previously have had. If there is some sort of train of thought one can go down, which ends with 'help I'm trapped in the wrong body' when they would otherwise not have had this problem, then you do not prompt them to start this train of thought. For mostly the same reason, you don't ask children "do your friends drink vodka?".
Essentially, its conceivably possible that the idea of transsexualism poses an information hazard to children.
the idea of transsexualism poses an information hazard to children
Of the same magnitude as the idea of drinking alcohol, shooting guns, or doing stupid things on video..?
I tend to think that in the age of internet-connected smartphones the concept of protecting children from information hazards is... quaint and counterproductive.
Having said that, I would interpret the events which led to this discussion as authorities attempting to shape the kids' value system which is a different and, probably, a more dangerous thing.
I would say that smartphones should have age filters on them
I agree. We should encourage children to develop an interest in anonymous filter-dodging web access systems like Tor, securely encrypting their messages such that they can't be monitored for inappropriate language usage, and other related skills while they're still young.
I don't understand. Nothing in the article you linked to describes anyone
encouraging children to be gay and transsexual
and the article isn't about what schools do, or even about what one school does. It's about what some government inspectors are alleged to have done, and I think a little context might be in order.
This is about the inspection of Grindon Hall Christian School. I think it's clear that the inspectors were concerned that the school might be instilling hostility to, and/or ignorance of, various things that conservative Christians commonly disapprove of: other religions, homosexuality, transsexualism. So they asked pupils some questions intended to probe this.
The school has issued a complaint about those questions. (This is where the stuff in the Telegraph article comes from.) The inspection report, now it's out, is extremely negative.
If the complaint made by the school is perfectly accurate, then it does sound as if the probing was done quite insensitively. Tut tut, naughty inspectors. But it's worth noting that complaints of this sort -- especially when, as one might suspect here, they're made partly in self-defence -- are not always perfectly accurate. And, e.g., ...
Could use an editor or feedback of some kind for a planned series of articles on scarcity, optimization, and economics. Have first four articles written and know what the last article is supposed to say, and will be filling in the gaps for a while. Would like to start posting said articles when there is enough to keep up a steady schedule.
No knowledge of economics required, but would be helpful if you were pretty experienced with how the community likes information to be presented. Reply to this comment or send me a message, and let me know how I can send you the text of the articles.
I read a book from a guy who writes many funny stories about animals (sorry, I don't remember his name now). He described how ZOOs often try to provide a lot of space for animals... which is actually bad for non-predators, because their instinct is to hide, and if they cannot hide, they have high levels of stress (even when nothing is attacking them at the moment), which harms their health. Instead, he recommended to give the animals a small place to hide, where they will feel safe.

An ancient extrasolar system with five sub-Earth-size planets

A few day ago, I saw an interesting article on a site somewhat related to lesswrong. Unfortunately I didn’t have the time to read it, so I bookmarked it.
Computer crashed, lost my last bookmarks and now I spent 2 hours trying to find this article, without luck. Here is the idea of the article, in a nutshell : we human are somewhat a king of learning machine, trying to build a model of the “reality”. In ML, overfitting means that in insisting too much on fitting the data, we actually get a worse out-of-sample performance (because we start to fit the modeling...
A self-improvement inquiry. I've got an irrational tendency to be too relaxed around other people; too sincere, transparent, and trusting. In general I'm very uninhibited and uncontrolled, and this goes to spectacular levels when I'm the slightest bit intoxicated. This has come back to bite me in more than one occasion.
I've had trouble finding documentation on how to improve on this. "Being too honest/sincere/open" doesn't seem like a common problem for people to have.
Other than Superintelligence and Global Catastrophic Risks what should I read to find out more about existential risk?
I still don't understand the apparently substantial difference between Frequentist and Bayesian reasoning. The subject was brought up again in a class I just attended—and I was still left with a distinct "... those... those aren't different things" feeling.
I am beginning to come to the conclusion that the whole "debate" is a case of Red vs. Blue nonsense. So far, whenever one tries to elaborate on a difference, it is done via some hypothetical anecdote, and said anecdote rarely amounts to anything outside of "Different people somet...
...A cool fact about the human brain is that the left and right hemispheres function as their own little worlds, each with their own things to worry about, but if you remove one half of someone’s brain, they can sometimes not only survive, but their remaining brain half can learn to do many of the other half’s previous jobs, allowing the person to live a normal life. That’s right—you could lose half of your brain and potentially function normally.

I think in many professions you can categorize people as professionals or auteurs (insofar as anyone can ever be classified, binaries are false, yada yada).
Professionals as people ready to fit into the necessary role and execute the required duties. Professionals are happy with "good enough", are timely, work well with others, step back or bow out when necessary, don't defend their visions or ideas when the defense is unlikely to be listened to. Professionals compromise on ideas, conform in their behavior, and to some degree expect others to do t...

Politics as entertainment
For many policy questions I normally foresee long term 'obvious' issues that will arise from them. However, I also believe in a Singularity of some sort in that same time frame. And when I re-frame the policy question as will this impact the Singularity or matter after the Singularity the answer is usually no to both.
Of course, there is always the chance of no Singularity but I don't give it much weight.
So my question is: Has anyone successfully moved beyond the policy questions (emotionally)? Follow up question: once you are bey...

Are human ethics/morals just an evolutionary mess of incomplete and inconsistent heuristics? One idea I heard that made sense is that evolution for us was optimizing our emotions for long term 'fairness'. I got a sense of it when watching the monkey fairness experiment
My issue is with 'friendly ai'. If our ethics are inconsistent then we won't be choosing a good AI but instead the least bad one. A crap sandwich either way.
The worst part is that we will have to hurry to be the first to AI or some other culture will select the dominate AI.

It's worth estimating when existential risks are most likely to occur, as knowing this will influence planning. E.g. If existential risks are more likely to occur in the far future, it would probably be best to try to invest in capital now and donate later, but if they are more likely to occur in the near future, it would probably be best to donate now.
So, what's everyone's best estimates on when existential catastrophes are most likely to occur?
The BBC has an article about how Eric Horvitz (director of Microsoft Research's main lab) doesn't think AI poses a big threat to humanity.
Not a very high-quality article, though. A few paragraphs about how Horvitz thinks AI will be very useful and not dangerous, a few more paragraphs about how various other people think AI could pose a huge threat, a few kinda-irrelevant paragraphs about how Horvitz thinks AI might pose a bit of a threat to privacy or maybe help with it instead, the end.
Apparently Horvitz's comments are from a video he's made after getting...
Sublinear pricing.
Many products are being sold that have substantial total production costs but very small marginal production costs, e.g. virtually all forms of digital entertainment, software, books (especially digital ones) etc.
Sellers of these products could set the product price such that the price for the (n+1)th instance of the product sold is cheaper than the price for the (n)th instance of the product sold.
They could choose a convergent series such that the total gains converge as the number of products sold grows large (e.g. price for nth item = ...
Small observation of mine. While watching out for sunk cost fallacy it's easy to go to far and assume that making the same spending is the rational thing. Imagine you bought TV and the way home you dropped it and it's destroyed beyond repair. Should you just go buy the same TV as the cost is sunk? Not neccesarily - when you were buying the TV the first time, you were richer by the price of the TV. Since you are now poorer, spending this much money might not be optimal for you.
Does anybody here have a lot of knowledge in social psychology who has an opinion on the elaboration likelihood model (ELM)? The model appears to me to be tautological, but the sources I've looked at seem to indicate it's widely accepted. It feels to me as if the central route vs. peripheral route is determined essentially by whether the participant tells you it's central or peripheral and strong or weak arguments similarly are determined by the participant's opinion, and not any objective measure. The model throws off my BS detector, but I can't dismiss it when a lot of researchers specializing in this field seem to think very highly of it.
I said before that I was going through Lepore's Meaning and Argument. I was checking my answers for exercise 4.3 when I get to solution #27 and read:
Ambiguous. It is not the case that (John beats his wife because he loves her); because he loves her, it is not the case that John beats his wife.
To which I reply, "Whoaaaa." To be clear, problem #27 reads:
I don't think John will arrive until Tuesday.
which appears to be related to solution #28, and there are 30 problems and 31 solutions. Looks like they removed the problem but not the solution.
Tighten up, Lepore. (And Lepore's editor.)
The Intelligence was confined for security reasons. Eventually people became tempted that things might be much better off to have the Intelligence working in the real world outside of confinement. However people were also working on making the Intelligence safer. To evaluate whether the work was successful or whether it ever could be usefull a Gatekeeper was assigned. During their training the Gatekeeper was reminded that the Intelligence didn't think like he did. It's kind was known to be capable of cold blooded deception where humans like the Gatekeeper ...
What value do you assign to your leisure time, when deciding if something is worth your time? For example, do I want to spend 2 hours building something or hire someone to do it. It feels incorrect to use my hourly pay, because if I save time on a Sunday, I'm not putting that time to work. I'm probably surfing the internet or going to the gym, the sort of things people generally do in leisure time. It has value to me, but not as much as an hour of work. What do you suggest?
Does anyone else love Curb Your Enthusiasm? I have a hypothesis that it's especially appealing to rationalists.

MW vs MIW mental models
A standard description of Multiple Worlds is that every time a particle can do more than one thing, the timeline branches into two, with the particle doing X in one new branch and Y in the other. This produces a mental model of a tree of timelines, in which any given person is copied into innumerable future branches. In some of those branches, they die; in a few, they happen to keep living. This can lead to a mental model of the self where it makes sense to say something like, "I expect to be alive a century from now in 5% of th...

I believe many philosophies and ideologies have hangups, obsessions, or parasitical beliefs that are unimportant to most of the beliefs in practice, and to living your life in concordance with the philosophy, yet which are somehow interpreted as central to the philosophy by some adherents, often because they fit elegantly into the theoretical groundings.

Christians have murdered each other over transubstantiation vs consubstantiation. Some strands of Libertarianism obsess over physical property. On this forum huge amounts of digital ink are spilled over Many-Worlds Interpretation.
One of these is not the like the others. The first one is killing over something that likely doesn't exist. The others are a bit different from that. The second one is focusing on a coherent ideological issue with policy implications. The third one may have implications for decision theory and related issues. Note by the way that if the medieval Christian's theology is correct then the the first thing really is worth killing over: the risk of people getting it wrong is eternal hellfire. Similarly, if libertarianism in some sense is correct then figuring out what counts as property may be very important. Similar remarks about to MWI. The key issue here seems to be that you disagree with all these people about fundamental premises.
