In other Peoples Shoes

Part of Philosophy with Children Sequence

"Assume you promised your aunt to play with you nieces while she goes shopping and your friend calls and invites you to something you'd really like to do. What do you do?"

This was the first question I asked my two oldest sons this evening as part of the bed time ritual. I had read about Constructive Development Theory and wondered if and how well they could place themselves in other persons shoes and what played a role in their decision. How they'd deal with it. A good occasion to have some philosophical talk. This is the (shortened) dialog that ensued:

The immediate answer by A: "I will watch after the girls."

Me: "Why?"

A: "Because I promised it."

B: "Does A also promise it and get a call?"

Me: "This is about your nieces and your friend, not about your brother."

B: "But I need this for my answer."

Me: "I don't see why, but OK, assume that he is not involved."

B: "Because I would ask him whether he might play with the girls in exchange for a favor."

Me: "OK, but please assume that ... (read more)

Reading the preface to Science and Sanity by Korzybski:

From its very inception, the discipline of general semantics has been such as to attract persons possessing high intellectual integrity, independence from orthodox commitments, and agnostic, disinterested and critical inclinations. (...) For them, authority reposes not in any omniscient or omnipresent messiah, but solely in the dependability of the predictive content of propositions made with reference to the non-verbal happenings in this universe. They apply this basic rubric as readily to korzybskian doctrine as to all other abstract formulations and theories and, like good scientists, they are prepared to cast them off precisely as soon as eventualities reveal them to be incompetent, i.e., lacking in reliable predictive content. This circumstance in itself should abrogate once and for all the feckless charges sometimes made by ill-informed critics that general semantics is but one more of a long succession of cults, having its divine master, its disciples, a bible, its own mumbo-jumbo and ceremonial rites. (...) Far from being inclined to repel changes that appear to menace the make-up of general semantics, they actively a

8cousin_it6yYeah, I guess LW rationality should be filed under "intellectual fads" rather than "cults".
4RichardKennaway6yWhat are the dynamics that produce a fad rather than growth into the mainstream? It might be worth CFAR thinking about that.
6ChristianKl6yIn the 20st century serious intellectual thought mostly became thought backed up by academia. Academia then had a custom that it didn't really like interdisciplinary departments but it tried to organize itself into nonoverlapping departments. Many departments were also pressured into doing research that's directly useful to corporations and that can produce patents. General Semantics and also Cybernetics are fields that lost as a result. I think there a good case that times change. With the Giving Pledge there a lot of Billionaire money that wants to fund new structures. OpenAI is one example of a well funded projected that likely wouldn't have existed in that form in the past. Sam Altman also wants to fund other similar research projects. The OpenPhilantrophy project is sitting on a lot of money that it wants to funnel into effective project without caring at all about departmental overlapping. A world where a lot of people live in their own filter bubble instead of living in the bubble created by mainstream media might also lack what we call mainstream at the moment. Yesterday I was at a Circling meetup in Berlin. I also read at the same day about the experience of an old Facebook friend that lives in the US that did a circling trainers training. In my filter bouble Circling is a global trend at the moment but that doesn't mean that it's mainstream. If we look at general semantics it's also worth noting that it both succeeded and failed. The phrase "The map is not the territory" is very influential. Neuro-linguistic Programming (NLP) is named that way because of Korzybski usage of the term neuro-linguistic. NLP is based on general semantics but it evolved a lot from that point. NLP is today an influential intellectual framework outside of the academic mainstream.
2Viliam6yI could imagine some good reasons for doing so. Sometimes scientists who are experts in one field become crackpots in another field, and it may be dificult for the new colleagues to argue against them if the crackpot can euler [http://slatestarcodex.com/2014/08/10/getting-eulered/] them by using the arguments from their old field. On the other hand, there is the saying that a map is not the territory, and this seems like suggesting that the existing maps can be modified in the middle, but the boundaries are fixed. But we have already seen e.g. computer science appearing at the boundary of mathematics; biochemistry appearing on the border between biology and chemistry; or game theory somewhere at the intersection of mathematics, economy, and psychology.
2ChristianKl6yMy argument is primarily about whether that historical development was good or bad. It was that there are reasons why certain memes won over others that aren't directly about the merit of the memes. Additionally I make the prognosis that those reasons are less likely to hold in the next 40 years the way they did in the last 40. Today computer science is very much a subfield of math. Heinz von Foerster had a psychatrist in his Biological Computer Laboratory. He wanted to study computing, system theory, cybernetics or whatever word you want to use broadly. The Biological Computer Laboratory was shut down when the military came to the point of deciding that funding it doesn't produce militarily useful results. As far as I know we don't have professors for game theory as a discipline. We have economic professors who study game theory, mathematics professors who study it and psychology professors who study it. We don't have departments of game theory.
0mwengler6yNever heard of Circling until your post. Looked it up, initially find nothing going on in San Diego (California US). I wonder if it is more of a European thing? If you know how I can find something local to San Diego CA US, please let me know.
4TimS6yLikely strong factors include: * Ease of applicability. If the average middle manager cannot apply a technique easily or straightforwardly while working, the major pressure to use a technique will be social signalling (cf. corporate buzzword speak). * Measurable outcomes. If the average middle manager cannot easily observe that the technique makes her job easier (either the productivity of subordinates or her control over them), then she will have no reason to emotionally or intellectually invest in the technique.
3username26yBecoming a niche is a third possibility if ideas are suitable to one area but hard to expand to different areas.
1mwengler6yI do think rationality is a niche. I had a conversation with a not-particularly-bright administrative assistant at work where she expressed the teachings of Jehovah's Witness as straightforward truth. She talked some of the chaos of her life (drugs, depression) before joining them. As I expressed the abstract case for, essentially, being careful about what one believes, it seemed clear enough to me that she had little or nothing to gain by being "right" (or rather adopting my opinion which is more likely to be true in a Bayesian sense) and she seemed to fairly clearly have something to lose. I, on the other hand, have a philosopho-physicist's values and also value finding regular (non-theological) truths by carefully rejecting my biases, so I was making a choice that (probably) makes sense for me. When my 14 year old daughter (now 16 and doing much better) was "experimenting" with alcohol, marijuana, and shop-lifting, I had a "come to Jesus" talk with my religious cousin. She told me that I knew right from wrong and that I was doing my daughter no favors by teaching her skepticism above morality. I decided she was essentially correct, and that some of my own "skepticism" was actually self-serving, letting me off the hook for some stealing I had done from employers starting when I was about 15. I view rationality as a thing we can do with our neocortex. But clearly we have a functional emotional brain that "knows" there are monsters or tigers when we are afraid of the dark and "knows" that girls we are attracted to are also attracted to us. I continue to question whether I am doing myself or my children any real favors by being as devoted to this particular feature of my neocortex as I am.
2username26yWithout numbers it sounds more like a sales pitch rather a honest analysis.
4PipFoweraker6yI think that's a reasonable position for a preface to take.
2Gunnar_Zarncke6yI had a comparable impression from reading Cybernetics [http://www.goodreads.com/book/show/294941.Cybernetics] (at least the parts I got to so far) and other books on system theory.
6Vaniver6yI think cybernetics the practice / math is alive and well, even if cybernetics the name is mostly discarded. Take a look at Wiener's wiki page: The right way to read that is that it's used in seven fields, not zero.
7ChristianKl6yCybernetics is alive but I think it's misleading to call it well. When talking about an issue like weight loss the dominating paradigm is "calories in, calories out" and not a cybernetics inspired paradigm. We don't live in a world where any scale on the market allows automatic calculating of the moving averages of the hacker diet. Quantified Self as movement is based on Cybernetics. At first European conference Gary spoke about how cybernetics is not well. I had an old professor in university who taught physiology based on regulation system thinking (cybernetics but he didn't use the word cybernetics). According to him there's was no textbook that presents that perspective we could use for the course.
2Viliam6ySo it seems like cybernetics was dissected and some of its parts were digested by various disciplines, but the original spirit which connected those parts together was lost. An analogy for the rationality movement would be if in a few decades some of the CFAR or MIRI lessons will become accepted material in pedagogics, physics, or maybe even AI research, but the whole spirit of "tsuyoku naritai" will be forgotten. Some parts that I guess are likely to survive, because they can fit in the existing education: * treating emotions as rational or irrational depending on whether they relate to facts (psychology) * planning fallacy (management) * illusion of transparency (pedagogics) Some parts that I guess are likely to be ignored, because they seem too trivial, and don't fit to the existing educational system. They may be mentioned as a footnote in philosophy, but they will not be noticed, because philosophy already contains millions of mostly useless ideas: * making beliefs pay rent * noticing confusion * fake explanations * mysterious answers * affective spirals * fallacy of grey * dissolving the question * tsuyoku naritai * rationality as a common cause of many causes EDIT: Reading my lists again, seems like the main difference is between things you can describe and things you have to do. The focus of academia is to describe stuff, not to train people. Which makes sense, sure. Except for the paradoxical part where you have to train people to become better at correctly describing stuff.
3Viliam6yI haven't read the book, but looking at the reviews on the page you linked... That's like Eliezer from a parallel universe, except that in this parallel universe the alternative Eliezer was a professor of mathematics at MIT.
1ChristianKl6yNot everything that has 'semantics' written on it is 'general semantics'. The academic seminars on semantics rather see themselves in the tradition of linguistics.
0TimS6yYes. That assertion threw up a red flag that the author was overstating the importance of the methodology.

Please share something you consider a positive characteristic of another LessWronger that you haven’t shared elsewhere :)

It may not seem so, but I actually enjoy debating Lumifer. He never fails to show me where I'm wrong.

2[anonymous]6ythat's a really good one. Lumifer is wonderful!
9philh6yIlyaShpitser is really good at calling out people who are using bayes etc. as applause lights. It's valuable and entertaining.
7[anonymous]6yVaniver and FrameBeningly answer my questions in an understandable and friendly way. (Other people do, too, I just have an easier time deciding to PM those two.) I also pattern-match them to a couple of very good friends in RL, which is why 1) I don't think your formulation is really meaningful, 2) I want them to know, if they are reading this, that I might go to greater lengths in helping them than is rationally expected considering we've never met.

Is here any interest in posts about parenting with a lesswrong touch?

Mental Images Part of Philosophy with Children

This evening my oldest asked me to test his imagination. Apparently he had played around with it and wanted some outside input to learn more about what he could do. We had talked about https://en.wikipedia.org/wiki/Mental_image before and I knew that he could picture moving scenes composed of known images. So I suggested

  • a five with green white stripes - diagonally. That took some time - apparently the green was difficult for some reason, he had to converge there from black via dark-green
  • three mice
  • three mice, one yellow, one red, and one green
  • the three colored mice running behind each other in circles (all no problem)
  • he himself
  • he himself in a mirror looking from behind (no problem)
  • two almost parallel mirrors with him in between (he claimed to see his image infinitely repeated; I think he just recalled such an experiment we did another time).
  • a street corner with him on the one side and a bike leaning an the other wall with the handlebar facing the corner and with a bicycle bell on the left side such that he cannot see the bike.

3NancyLebovitz6ySparks of Genius [http://www.amazon.com/Sparks-Genius-Thirteen-Thinking-Creative/dp/0618127453] has a lot of challenges for the imagination. What geometrical figure has a circular cross section and a square cross section? Circular, square, and triangular cross sections?
3Gunnar_Zarncke6yThat book looks interesting. Added it to my wish list. Here is a summary: http://vnthomas1.blogspot.de/2009/06/sparks-of-genius-13-thinking-tools-of.html [http://vnthomas1.blogspot.de/2009/06/sparks-of-genius-13-thinking-tools-of.html]
3Gunnar_Zarncke6yWe talked about 3D objects being square from one side and circle from the other - for example a cylinder. But he rejected this approach (though he was able to visualize the form). He considered taking circle and square apart and putting it back together into something like a rounded square but rejected that too as neither square nor circle.
2NancyLebovitz6yMy guess is that your son doesn't have a solid grasp of the idea of a cross section. Actually, I don't quite feel good about a cylinder having a square cross section. It's as though it's wrong to neglect the idea that a cylinder is round.
4Vaniver6yConsider a square in front of you with its edges horizontal and vertical. (Say, drawn on your monitor.) Then consider the line running from the top of the square to the bottom of the square that passes through the center of the square. What happens when you rotate the square around that line?
2Gunnar_Zarncke6yThat was also my first impression. But we talked about it a bit longer. I think it clicked when he mentioned how he looked (in imagination) at the form such that the top becomes a straight line (like looking a paper from the side) and the same with the bottom.
0moridinamael6yI think your link didn't happen correctly.
0NancyLebovitz6yThanks for letting me know.
0Baughn6yI am now imagining a square circle. That's interesting.
2Gunnar_Zarncke6yCan you describe it?
2Baughn6yIt's circular, and square. That's literally all there is. I can't imagine it visually, the way I usually would. Wonder why. :P
2Gunnar_Zarncke6y― Lewis Carroll See also this article [http://www.news.ucsb.edu/2015/016055/impossible-things] discussing the usefulness of believing impossible things.
0roystgnr6yI can imagine it. You just have to embed it in a non-Euclidean geometry. A great circle can be constructed from 4 straight lines, and thus is a square, and it still has every point at a fixed distance from a common center (okay, 2 common centers), and thus is a circle.
4gjm6yThe four straight lines in your construction don't meet at right angles.

Oh, dear. A paper in PNAS says that the usual psychological experiments which show that people have a tendency to cooperate at the cost of not maximizing their own welfare are flawed. People are not cooperative, people are stupid and cooperate just because they can't figure out how the game works X-D

Abstract:

Economic experiments are often used to study if humans altruistically value the welfare of others. A canonical result from public-good games is that humans vary in how they value the welfare of others, dividing into fair-minded conditional cooperators, who match the cooperation of others, and selfish noncooperators. However, an alternative explanation for the data are that individuals vary in their understanding of how to maximize income, with misunderstanding leading to the appearance of cooperation. We show that (i) individuals divide into the same behavioral types when playing with computers, whom they cannot be concerned with the welfare of; (ii) behavior across games with computers and humans is correlated and can be explained by variation in understanding of how to maximize income; (iii) misunderstanding correlates with higher levels of cooperation; and (iv) standard co

... (read more)
4Kaj_Sotala6yThat sounds like it would contradict the results on IQ correlating positively with cooperation [http://slatestarcodex.com/2015/12/08/book-review-hive-mind/]:
6gwern6yOnly if you assume that IQ is independent of altruism. Given that IQ covaries with altruism, patience, willingness to invest, willingness to trust strangers, etc, I don't see why you would make that assumption. I'm fine with believing that greater IQ also causes more cooperation and altruism and so high IQ players understand better how to exploit others but don't want to. If anything, the results suggest that the relationships may have been underestimated, because lower IQ subjects' responses will be a mix of incompetence & selfishness, adding measurement error.
1Kaj_Sotala6yGood point.
2Gurkenglas6y(ii) They may also be anthropomorphizing the computers. (iii) This just means that the sort of person who cooperates in this sort of game also treats humans and computers equally, right?
0Lumifer6yI would count it as supporting evidence for "they're just stoopid" hypothesis X-)
1mwengler6yDoes "value the welfare of others" necessarily mean "consciously value the welfare of others"? Is it wrong to say "I know how to interpret human sounds into language and meaning" just because I can do it? Or do I have to demonstrate I know how because I can deconstruct the process to the point that I can write an algorithm (or computer code) to do it? The idea that we cannot value the welfare of computers seems ludicrously naive and misinterpretative. If I can value the welfare of a stranger, then clearly the thing for which I value welfare is not defined too tightly. If a computer (running the right program) displays some of the features that signal me that a human is something i should value, why couldn't I value the computer? We watch animated shows and value and have empathy for all sorts of animated entities. In all sorts of stories we have empathy for robots or other mechanical things. The idea that we cannot value the welfare of a computer flies in the face of the evidence that we can empathize with all sorts of non-human things fictional and real. In real life, we value and have human-like empathy for animals, fishes, and even plants in many cases. I think the interpretations or assumptions behind this paper are bad ones. Certainly, they are not brought out explicitly and argued for.
0Jiro6yI actually read the paper. ((iii) and (iv) apply to the general case of "people behave as if they are playing with humans", but not to the specific case of "people behave as if they are playing with humans, because of empathy with the computer").
0Lumifer6yI am always up for being ludicrous :-P So, what is the welfare of a computer? Does it involve a well-regulated power supply? Good ventilation in a case? Is overclocking an example of inhumane treatment? Or maybe you want to talk about software and the awful assault on its dignity by an invasive debugger...

Do we have a way to measure how happy farm animals happen to be? If we don't than developing a metric might produce huge gains in animal welfare, because it allows us to optimize for it better.

Temple Grandin has some work that's relevant, and argues for quantitative measures. One of the easy metrics to use now are bodily integrity things, like the percentage of animals who are lame when they make it to the slaughterhouse. A lame animal is unlikely to be a happy or well-treated animal, and it seems easy to measure and compare.

She's also done work on what animals are willing to take some trouble to get-- chickens apparently care more about having a secluded place to lay eggs than they care about getting outside.

5Gunnar_Zarncke6yWhich reminds me: Would it be ethical to reduce animal suffering by somehow breeding suffering out of animals? Or asked differently: Is suffering a simple concept (that can be selected against) or is it just negative value with all the associated complexity? Or doesn't this apply to animals? Obligatory hitchhikers quote [http://remotestorage.blogspot.de/2010/07/douglas-adamss-cow-that-wants-to-be.html] .

This is tricky, because if we don't understand (on the technical level) how "qualia" work, we cannot be sure if we are breeding for "less suffering" or merely "less ability to express suffering".

In other words, now the humans could play the role of the unfriendly AI who "would rip off your face, wire it into a permanent smile, and start xeroxing".

3PipFoweraker6yI'm not certain if we need to understand how suffering works if we can simply remove the organs that house it. It seems less tricky when a technological set of solutions come along that allow delicious engineered meat to be grown without all the unnecessary and un-delicious bits. I think the in vitro meat industry will have an extraordinarily good time when things develop to the point of being able to synthesis a lazy-person's whole stuffed camel.
1Viliam6yIn vitro meat -- okay. Modifying animals so they can't scream -- not okay. -- this is the part that IMHO depends on details we may not yet understand sufficiently.
0Dagon6yIn-vitro meat reduces suffering, but also reduces joy and brain-experienced life in general. I don't know how to evaluate if a current cow or chicken's life is negative value (to the animal) or not.
1PipFoweraker6yIf I'm exclusively limiting myself to animals that are raised in an organised fashion for eventual slaughter, I don't think I need too much data to assign broadly negative values to lives that are unusually brutish, nasty and short compared to either non-existence or a hypothetical natural existence. In my consideration, simple things like the registering of a pain stimulus and the complexity of behaviour to display distress are good enough indicators.
2AstraSequi6yI don't think you can make that decision so easily. They're protected from predators, well-fed, and probably healthier than they would be in the wild. (About health, the main point against is that diseases spread more rapidly. But farmers have an incentive to prevent that, and they have antibiotics and access to minimal veterinary treatment.) This leads me to conclusions I disagree with - like if a person is murdered, then their life had negative value.
1Dagon6yThe comparison at hand is only to non-existence; you're not proposing any mechanism to improve such lives or to make them similar to a hypothetical nature, only to eliminate any experience of the life while still providing the meat. As such, you don't need too much data, but you currently have none, nor even a theory about what data you'd want. Trying to determine a preference for non-existince in animals (or vegetables, for that matter, or lumps of vat-meat) when such units don't seem to have the concepts (or at least the communication ability) to make choices for themselves doesn't seem obvious at all to me.
-2PipFoweraker6yWhen animals are created and destroyed solely for a purpose attributed to them by their human overlords, that reduces their utilisable preferences to zero or near zero. Unless a meat producer had reason to believe that inflicting pain on an animal improved the resulting meat product, that pain would almost certainly be a by-product of whatever the farmer chose rather than an exclusive intent. I personally know no farmers that inflict 'pointless' injury on their livestock. Given any amount of suffering in the animal stock needed to feed, say the US compared to a zero amount of suffering of the in-vitro meat needed to feed the US, if we were basing decisions solely on the ethics of the situation the choice would be clear-cut. As it stands it is simply one amongst many trade-offs, the numbers and data of which I agree would be laborious to define. The inability to communicate or even experience a preference for the concept of non-existence compared to an experienced or ongoing pain does not invalidate the experience of the pain. In this field of thought I am happy to start from a non-rigorous framework and then become more so if needs be. At a simple level, my model says [for SolvePorkHunger: 'no pig' > 'happy pig + surprise axe' > 'sad pig + surprise axe']. The practical ways to improve such lives as already exist are, broadly speaking, answered by practitioners of veganism, vegetarianism, cooperative existence with animals (raising chooks, goats for milk, etc etc).
5MrMind6yAlthough I can understand the intuitiveness of this ordering, I think it should be pondered more deeply. It's safe to say that no pig experiences no joy and no suffering, and that sad pig experiences lots of suffering. Also it would seem intuitive that a happy pig dying of natural causes experiences lots of joy. From the point of view of the animal: long lived sad pig < short lived sad pig < no pig < long lived happy pig It is weird not to put short lived happy pig were it seems to belong, and I think it has to do with the fact that killing a happy pig carries a lot of negative moral weight. Would you say the same about a pig genetically engineered to die of natural causes when it's most delicious?
2Dagon6yOoh! I love the point about it being morally heavier to kill and eat a happy animal than a sad one. I tend to think even relatively sad lives are not absolutely negative - very nearly any life is better than none, and a good life better than a bad one, but it's going to give some of my fuzzy-vegetarian friends a good question to ponder.
2Dagon6yDoes this argument apply to humans created or destroyed solely for purposes of evolutionary pressure or environmental accident? I'd argue that nothing happens solely for any purpose. Measured how? This seems to be the crux of your position. I don't buy it. Let's leave aside (unless you want to try to define terms) the difference between happy, sad, and more common mixed cases. Let's focus on the main inequality of nonexistence vs some temporary happiness. Would you say 'no human' > 'happy human + surprise cancer'? I assert that neither human nor pig really frames things in terms of the farmer's or universe's motivations.
0mwengler6yWould this also mean 'no pig' > 'happy pig + surprise predator' > 'sad pig + surprise predator' I don't think nature is generally any better than (some kinds of) farming for prey animals. Should vegans be benefitting from lowering the birth rates among natural animals? Or for that matter, does it also mean 'no human' > 'happy human + eventual death' > 'sad human + eventual death' Even in nature, all life is alive, and then it dies, almost always in a way it would not choose or enjoy. Does life just suck? Are we bad actors for having children?
2Vaniver6yThe term to search for is 'wild animal suffering.' The term to search for is 'anti-natalism.'
0IlyaShpitser6yPeople who worry that life sucks that much should make sure they correctly priced in the possibility that we can figure out how to arrange it so that life is super great in the future. (But everyone here realizes this).
2mwengler6yWould it be ethical to grow meat in a vat without a brain associated with it? Personally, I think pretty clearly yes. So breeding suffering out of animals would seem to be between growing meat in a vat and what we have now. So it would seem to be a step in the right direction. We, and animals, almost certainly have suffering because it had survival value for us and animals in the environment in which we evolved. Being farmed for meat is not that environment. I don't think removing suffering from our farmed animals has a downside. Of course, removing it from wild animals would probably not be a good thing, but would probably correct itself relatively quickly in the failure of non-suffering animals to survive.
2Gunnar_Zarncke6yI wonder about more intermediate stages. Animals suffering less is one obviously. Animals with less nervous systems would be another (though probably not practical). More ideas?
1Jiro6yMost vegetarians would think that activities that normally make animals suffer are bad in themselves. They may have originally have used suffering as a reason to figure out that those activities are bad,m but they're bad in themselves. You can't just take away the bad consequences and make them good. Also, utilitarianism has a problem with blissful ignorance. Most vegetarians would probably think that animals that are engineered to be unable to suffer have a blissful ignorance problem; they are being harmed and just don't realize it.
2Lumifer6yDo carrots have a blissful ignorance problem, then?
0Jiro6yThe problem only exists for beings with some sort of mind that has moral relevance. I would guess that most vegetarians believe that animals have such a mind, but not carrots.
0Lumifer6ySo what happens when you engineer a "mind that has moral relevance" out of an animal? And going a bit upthread, what do you mean by acts that are "bad in themselves"?
0Jiro6yI'm not a vegetarian myself. I was just describing how people think. I don't know that they have a coherent concept of "acts that are bad in themselves".
0mwengler6yPresumably the moral win in reducing or eliminating the suffering of farmed meat would have more to do with non-vegetarians than vegetarians. But really, is the point here to do something better than is already done, or is to impress vegetarians?

I was on vacation, confident that Clarity would have opened the new open threads. Since it wasn't the case, I'm resuming from today the 'duty' of creation of such threads. Happy LessWronging.

0[anonymous]6yEvidence for an inefficient market for karma for public goods like open threads on LessWrong. I assumed we would adapt [http://lesswrong.com/lw/l8/conjuring_an_evolution_to_serve_you/] to it after I attracted controversy for starting that open thread the other day. Maybe I've taboo'd non-MrMind's from doing instead and legitimised a kind of proprietary right to it to you!
2MrMind6yYeah, but why it would be inefficient? Entry cost is negligible and the need of open thread is very visible. I would rather say that there's no market because there's no demand: nobody cares that much about gaining that karma. Or maybe it's not a high status activity. Perverse incentives are everywhere! ;)
0Elo6yI wasn't watching... Should have jumped in myself... Sorry...
0MrMind6yNo problem, no harm has been effected, as far as I can see.

Interested if anyone has thoughts/research on this question:

Are chickens affected by the hedonic treadmill? If so, are they equally, more, or less susceptible to it? What about pigs?

0[anonymous]5yI have yet to find good research on this. However, if anyone out there believes that farm animals are affected by the hedonic treadmill, and that farm animal suffering causes great disvalue, prioritizing donations to the Humane Slaughter Association [http://www.hsa.org.uk/] (HSA) might be a good idea. Part of HSA's mission is to reduce the suffering of animals during slaughter, and I find it unlikely that farm animals hedonically adapt during their short and often intensely painful deaths. It seems more likely that a chicken hedonically adapts during its time in a battery cage. Brian Tomasik has a good piece on HSA here [http://reducing-suffering.org/why-i-support-the-humane-slaughter-association/].

6gwern6yHave you checked first that tattoos do not affect organ donation eligibility, or have any legal/medical weight whatsoever compared to, say, an organ donor card or check on your driver's license?
1Tem426yIt would be worth double-checking your local regulations, but tattoos do not generally restrict you from organ donation. You should make sure you get your tattoo from a licensed business, of course. As far as legal status -- that is a good question. I would think that as long as you updated it at least as often as you update your driver's licence, it would remain a valid indicator of your intent. That might mean adding a date to the tattoo, and adding another one every few years. You might contact your local hospital and see what they would do if they had a fresh corpse with no ID but a organ donor tattoo...
4ChristianKl6yWhy? Doctors have procedures for how to deal with organ donations. That procedure means looking at driver's license and organ donor cards. There are huge legal risks for them being creative.
0Tem426yI had to give up on trying to find out if a tattoo can count as consent on its own -- I would guess that it would be iffy territory unless you had it notarized and witnessed. It might still be worthwhile to have a tattoo; it does tell them that you have given consent, meaning that they will make an extra effort to look for consent (In the US this means a state database). This would only be relevant if you are found without your drivers license/ID. There are a number of fringe cases where you might be found dead and dying without easy access to your ID, but they are admittedly rare. They are also more likely to cases where your organs aren't usable (fire, ravaged by bears, rip tide carries you out to sea). However, if the legal team gets any head start on finding a John Doe's organ donor status, on average this is likely to result in increased organ salvage. Here's a revised suggestion, for social feasibility, effectiveness, and pain reduction: get a tattoo of a red heart and the words organ donor and your name in a protected area (e.g. on the side of your trunk, just below the arm pit). Until RDFI chips become common this is also probably one of your best protections against becoming a J. Doe (I mean, other than living a sane and safe life).
2ChristianKl6yThe core question isn't whether it can legally count as consent but whether the process that a medical team uses when it finds a dead body recognizes the tattoo.
1Tem426yI am not a first responder, but if I had a pile of corpses and one of them had an organ donor tattoo, that corpse would definitely be flagged for special attention and quick transport to the morgue. I wouldn't count on it being legal for them to make an extra effort to ID one body before another just based on (suspected) organ donor status, but making it into the refrigerator a bit earlier is a benefit.
0[anonymous]6yI don't have a driver's license, but taking into account the possibility of ...eligibility and what Tem24 said, it would seem definitely better to go about getting myself a card. Sorry, I just thought somebody could have already asked that before.
1Tem426yI think that optimal design would include the red heart that is placed on driver licences (in most American states) and on NHS cards (in the UK), plus the words "Organ donor". You might also want to include your organ donor ID, but you might not... in the US this is (sometimes? usually?) your driver's licence number, which may not be something you need strangers to see when you are at the beach. My understanding is that if you do not specify otherwise, it is assumed that they can take any organ they need, but if you wanted to clarify (or were worried that your relatives my get greedy about the parts you get buried with), I would expect that the words "no limitations" would be sufficient to allow the hospital to take any skin, eyes, etc., they feel they have a use for. Optimal wording may be less important than optimal placement. I would assume on the chest over the heart would be least likely to be destroyed in an accident / most likely to be seen by first responders... Plus, if that is destroyed, the best organs are also likely to be damaged. However, if you want optimal, you should really get a set of tattoos -- one for the chest, one for the stomach, and one for the neck(?).
0[anonymous]6yDamn, I'd better just get a card then. Thank you!
1Tem426yI wasn't arguing against the tattoo! It sounds like a good idea, and more likely to be seen than the card. (However, you should get the card and then plot the tattoo. A being on the local database and having your wishes known by your next-of-kin is your best bet to being effective in donating).
0[anonymous]6yYes, but I would rather suffer the small embarrassment of having the card with me on the beach than the pain of multiple tattoos, plus having to listen to my other-than-next-of-kin relatives' sighs and moans if they see the ones on appendages etc. (I have not had a single one yet, but I assume there is pain involved.)

Evidence for a distant giant planet in the Solar System

Recent analyses have shown that distant orbits within the scattered disk population of the Kuiper Belt exhibit an unexpected clustering in their respective arguments of perihelion. While several hypotheses have been put forward to explain this alignment, to date, a theoretical model that can successfully account for the observations remains elusive. In this work we show that the orbits of distant Kuiper Belt objects (KBOs) cluster not only in argument of perihelion, but also in physical space. We dem

There was a link (I think it was from Wedrifed) that allowed you to sort a particular user's posts/comments by karma (rather than by time). Does anybody know where that link is?

You mean Wei Dai's tool? eg http://www.ibiblio.org/weidai/lesswrong_user.php?u=gwern ? Works best with accounts with few comments...

0CurtisSerVaas6yYep! Thanks! Edit: I see what you mean about it being slow with accounts with lots of comments.
3Gunnar_Zarncke6yAnd now lots of people are thinking about who might be searched for insight. If it's Yvain then there are curated lists of that...
2CurtisSerVaas6yI'm basically going back over the sequences and top posts of LW again. I'm already aware of curated lists for Yvain and Kaj, but I don't think there are curated lists for the other top all-time posters. Unfortunately, A. That tool doesn't really work well enough. B. The list of all time top-posters has disappeared, and I'm sure I'd forget some of them if I tried to go off the top of my head.
2Gunnar_Zarncke6yThere used to be a ZIP download with all the posts. I just can't find that link though. An alternative is to mirror the site with wget and grep that.

So, I only recently decided to start taking Vitamin D after reading Gwern's discussion of it here, and I've been wondering if there are other easy wins for extending one's healthspan/life expectancy/lifespan cheaply that we're collectively missing.

On one level, it seems like having individual LWers go out, read a number of research papers, and then do a cost-benefit analysis on an intervention has produced good research before, but this approach feels a bit unorganized to me.

So, part of me wonders if it might be a good idea to just pay someone (say, Gwern,... (read more)

8James_Miller6yOther easy wins: The Squatty Potty [http://www.squattypotty.com/], magnesium supplements, meditation, and donating blood if you are male.
4PipFoweraker6yMy experience with giving people the data behind squatting to go to the dunny is that their awkwardness about it strongly outweighs, initially, their willingness to experiment. Which leads to the thought that there are probably some provably life-enhancing things that people don't even consider doing because it is so far outside their social mores that the possibility doesn't occur. I have had an entertaining few minutes trying to think of some that my great-descendants will be bewildered we didn't consider.
2James_Miller6yFecal transplants and cryonics.
2ChristianKl6ySeth Roberts nose clips while eating for people who want to lose weight probably falls under strong awkwardness that doesn't let people consider it.
2gwern6yI gave squatting a try a few months back. You can do the same thing by grabbing two cinder blocks and positioning them on either side of the toilet with the seat up. It felt slightly easier to defecate, but I couldn't figure out how to use it with pants as easily as regular sitting; you need to get out of one leg, almost, for it to work. And taking off my pants every time I need to defecate is a pain in the ass.
0Tem426yFor many people who on their own homes it would actually be feasible to build or install a pit toilet. I do not know of anyone in America who has done so. The cider-block idea sounds unstable... but I haven't tried it. However, it seems that it should be fairly easy to train your body to go just before you take a shower, assuming you take showers on a predictable schedule, thus solving the undressing inconvenience.
1gwern6yNo, the cinder-blocks were very stable. That was not the issue. I also think it's a little unreasonable to schedule your defecations and showers for the convenience of your squatting toilet rather than the other way around. Bidets are a big improvement but I'm not convinced by squatting for people without problems.
0[anonymous]6yAn anecdote: it was easy to train myself to go before I went on to yoga-like exercises (at home) which lasted more than an hour, although admittedly I was a teenager, one should have an instructor at hand at least in the beginning, one should shower after the exercises, and I did it 3-4 times a week. However, it also (seemed to) improve sleep quality.
0pepe_prime5yCould you elaborate on why squatting is a clear win? I took a brief look online and the evidence seems to favor squatting, but not hugely: https://skeptoid.com/blog/2015/09/26/squatty-potty/ [https://skeptoid.com/blog/2015/09/26/squatty-potty/] Regardless, thanks for the list!
0James_Miller5yThe cost of squatting is tiny, and part of the benefit is saved time so on net it seems like a clear win.
5Lumifer6yAverages are pretty useless -- go to a doctor, ask for a full set of blood tests. And when I say "full", I mean ridiculously all-encompassing, if your doctor is OK with this. The printout of your results should take a couple of dozen pages. Ask for copies of the lab results. Study them carefully and they will tell you personally what would be a good idea for your health.
1Tem426yIs that working under the assumption that normalizing is better for your health? I don't think that I would trust myself or my doctor to optimize supplements based simply on what I am low in. For example, normal vit. D3 levels are often set by the healthy level for Caucasians, with the result that Asians with healthy, normal levels for their genotype are flagged as dangerously low. This is not something that you can assume that your doctor is aware of. However, the tests would give you some starting points for research. Also, I suspect that most doctors are not likely to offer much more than a chem-20, which I think is pretty useful across populations (IANAD) -- but also is probably not what you are recommending.
0Lumifer6yNo. That's working under the assumption that more information is better than less information. I didn't say "listen to your doctor". I said "study them carefully". Ask for specific, comprehensive panels. Do not go in saying "You think I should maybe get some tests?" :-/

1[anonymous]6yAhh, screw the format. I’ll just post here to contain it in one place as it comes to me. I lie here in my hotel. Sometimes I think of relatively trivial matters compared to the recent tribulations: Í shouldn’t have prepaid my entire stay in this hotel. I should have taken it one night at a time’ I think. That may be wrong. There were some parts of the events of last night where my intuitions were gravely wrong. Both the hallucinations and the delusions offered insights: Let’s star with the comedic, but totally non-chronological. One gentleman at a bar I stopped for some food seemed like mafia to me. It turned out he was a gay guy who upon noticing me, did the surrepticious gay secret ritual for wanting me to follow him to his hotel room. If I was in the mood and not drug-fucked, I might have obliged. Importantly, it’s unlikely that there would be an openly gay russian mafioso because of the homophobia among Russians and machismo of criminals. I noticed upon leaving that the bar was called Same Same and the servers came across as pretty gay. So I was delusional. My insight fluctuated throughout the night but remained under a threshold. For one, I couldn’t will myself to consciously test items on scales of insight that I otherwise can vaguely remember if I’m primed with the memory. And indeed, during the peak of the trip I did WANT to test myself since it often increases my self-awareness: I just couldn’t do it. During that peak: what felt like several hours but I later inferred was under an hour, perhaps about 330 minutes or less. I pleaded out aloud for anyone who might be able to here me to evacuate me to a psychiatric ward or hospital immediately. It was, in retrospect, looking for positives, a respite from the paranoia of losing my valuables that has burdened me for the whole trip. Nevermind that I could not reconcile my visual and auditory information, nor my olfactory sensory data with one another. In a sense it was a moment of highly intentioned high stak
1[anonymous]6yI went on brief mental journeys. Things were still positive at this time. It was supposed to be a time of healing, retreating to my room. But, it would be the lead in to the negative parts. The mental journeys culminated in me making a few notes: I had been to hell and back: psychosis before without drugs. This was a reminder of what it could be like and importance of mental health..i know that this probably not cure depression, just brief serotonin boost, others have reported this, but now motivated to restart antidepressants and maybe antipsychotics I’m just on drugs, I thought. But that didn’t really help. I thought maybe it wasn’t mushrooms. It was the right duration, but so does LCD and some RC’s. The dangers of the unknown substance really scared me. Also my history of mental health scared me in that it may have precipitated on ongoing psychosis, or HPPD. I think about the phone monkey cliff mafia. They might be disinformants

Rant mode on:

Whenever Hawking blurts something out, mass media spread it around straight away. While he is probably OK with black holes, when it comes to global risks, his statements are not only false, but, one could say, harmful.

So, today he has said that within the millennia to come we’ll face the threat of creating artificial viruses and a nuclear war. This statement brings all the problems to about the same distance as that to the nearest black hole.

In fact, both a nuclear war and artificial viruses are realistic right now and can be used during our l... (read more)

3gjm6yI think you're reading things into what he said that he never intended to put there. His central claim is certainly not a reassuring, relaxing one: disaster is "a near certainty". He says it'll be at least a hundred years before we have "self-sustaining colonies in space" (note the words "self-sustaining"; he is not talking about a colony on Mars that "will die off without supplies") and that this means "we have to be very careful in this period". Yes, indeed, the timescale on which he said disaster is a near certainty is "the next thousand or ten thousand years". I suggest that this simply indicates that he's a cautious scientific sort of chap and doesn't like calling something a "near certainty" if it's merely very probable. Let's suppose you're right about nuclear war and artificial viruses, and let's say there's a 10% chance that one of those causes a planetary-scale disaster within 50 years. (That feels way too pessimistic to me, for what it's worth.) Then the time until there's a 99% chance of such disaster -- which, for me, is actually not enough to justify the words "near certainty" -- is 50 log(0.9)/log(0.01) years ... or about 2000 years. Well done, Prof. Hawking! Indeed, the statement that "migration to other planets automatically means salvation" is false. But that goes beyond what he actually said. A nuclear war or genetically engineered flu virus that wiped out most of the population on earth probably wouldn't also wipe out the population of a colony on, say, Mars. (You say "nuclear missiles would reach [Mars] as well", but why? Existing nuclear missiles certainly aren't close to having that capability, and there's a huge difference from the defensive point of view between "missiles have been launched and will hit us in a few minutes if not intercepted" and "missiles have been launched and will hit us in a few months if not intercepted".) You ask "Why namely 100 years?" but, at least in the article you link to, Hawking is not quoted as saying that
-2turchin6yI comment on what impression he translates to public, that risks are remote and space colonies will save us. He may secretly have other thoughts on the topic, but this does not matter. We could reconstruct his line of reasoning, but most people will not do it. Even if he thinks that risks are 1 per cent in next 50 years it results in 87 per cent in 10 000 years. I think that attempts to reconstructs some one line of reasoning with goal to get more comforting result is biased. For example one may said: "I want to kill children". But we know apriori that he is clever and kind man. So may be he started from the idea that he wants to make the world better place and may be he just wanted to say that he would like to prevent overpopulation. But I prefer to take claims on their face value. No matter who say it and what he may think, but didn't said. Self-sustain Mars colonies are able to create nukes on their own. If a war starts on Earth and if we have several colonies on Mars built by different countries, they could start war between each other too. In this case travel time for nukes will still be minutes - from one point on Mars to another. The history of WW2 shows that war between metropolis often resulted in the war in colonies (North Africa). Hawking has been quoted about AI in 100 years in another article about the same lectures.
3gjm6yThat's not my idea of "near certainty". That is not my goal, and I have no idea why you suggest it is. It doesn't appear to me that you are doing this in Hawking's case; rather, you are reading all sorts of implications into his words that they don't logically entail and don't seem to me to imply in weaker senses either. Sure, they could. But I don't see any particular reason to assume that they would.
0turchin6yWe don't know what Hawking meant by "near certainty" - 90 per cent or 99,999 per cent and depending on it we may come to different conclusion about what probability it implies for next 100 years. Most readers will not do this type of calculations anyway. They will learn that global risks is something that could happen in 1000 - 10 000 years time frame. And will discount it as unimportant. Your goal seems to be to prove that Hawking thinks thats global risks are real in near term future while he said exactly opposite. A lot of media starts to report Hawking claims in following words: "Professor Stephen Hawking has warned that a disaster on Earth within the next thousand or ten thousand years is a ‘near certainty'. http://www.telegraph.co.uk/news/science/science-news/12107623/Prof-Stephen-Hawking-disaster-on-planet-Earth-is-a-near-certainty.html [http://www.telegraph.co.uk/news/science/science-news/12107623/Prof-Stephen-Hawking-disaster-on-planet-Earth-is-a-near-certainty.html] While media may be not exact in repeating his claims and the wording is rather ambiguous, he didn't clarify them publicly as I know. About Mars. If colonies will be built by national states, for example there will be two colonies, American and Chinese, the war between US and China will result in war between their colonies with high probability, because if one side choose to completely destroy other side and its second strike capability it has to destroy all its remote military bases which may have nukes.
3gjm6yHe did not "say exactly opposite". He said: it'll be at least 100 years before we have much chance of mitigating species-level disasters by putting part of our species somewhere other than earth, so "we have to be very careful". My goal is to point out that you are misrepresenting what Hawking said. If these are genuinely self-supporting colonies on another planet, I think it will not be long -- a few generations at most -- before they stop thinking of themselves as mere offshoots of whatever nation back on earth originally produced them. Their relations with other colonies on Mars (or wherever) will be more important to them than their relations with anyone back on earth. And I do not think they will be keen to engage in mutually assured destruction merely because their alleged masters back on earth tell them to. (And if they are not genuinely self-supporting colonies, then they are not what Hawking was talking about.)
0turchin6yMy criticism should concentrate on two levels: on his wording and on his model of x-risks and their prevention. His wording is ambiguous than he speak about tens of thousand years - we don't have them. But I also think that his claims that we have 100 years (with small probability of extinction) and that space colonies are our best chance are both false. Firstly, because we need strong AI and nanotech to create really self-sustained colony. Self-replicting robots are the best way to build colonies. So we need to prevent risks of AI and nanotech before we create such colonies. And I think that strong AI will be created in less than 100 years. The same maybe said about most other risks - we could create new flu virus even now without any new technologies. Global catastrophe is almost certain in next 100 years if we don't implement protective measures here on Earth. The space colonies will not be safe from UFAI and from nanobots. Large space crafts maybe used as kinetic weapon against planets, so space exploration could create new risks. Space colonies also will not be safe from internal conflicts, as large colony will be able to create nukes and viruses and use it against another planet or another colony on the same planet or even in case internal terrorism. Only starships with near light speed maybe useful as escape mechanism as they could help spread civilization through Galaxy and create many independent nodes. Our best option to prevent x-risks are international control systems on dangerous tech and lately friendly AI, and we need to do it now, and space colonies have remote and marginal utility.
0ChristianKl6yHis claim is that we have 100 years in with we have to be extra careful to prevent Xrisk. With today's technology you could create a problematic new virus. On the other hand that hardly would mean extinction. Wearing masks 24/7 to filter air isn't fun but it's a possible step when we are afraid of airbone viruses. It's not like Hawkings doesn't call for AGI control.
0ChristianKl6yDo you really think that it's Hawking's position that at the moment there's no threat of nuclear war?
1turchin6yI don't think that he think so, I comment on what impression he translate to public, that risks are remote and space colonies will save us. He may secretly have other thoughts on the topic, but this does not matter.
0ChristianKl6yI don't think that it makes sense to give the full responsibility for a message to a person that's distinct from the author of an article. That said I don't think that saying: Although the chance of a disaster on planet Earth in a given year may be quite low, it adds up over time, becoming a near certainty in the next thousand or ten thousand years. makes any reader update to believe that the chance of nuclear war or genetically engineered viruses are lower than they previously expected. Talking with mainstream media inherently requires simplying your message.Focuses the message compounding of risk over time doesn't seem wrong to me.
0turchin6yIf he write an article about his understanding of x-risks timeframe and prevention measures timeframe with all fidelity he use to describe black holes we could concentrate on it. But now it may be wise to said that the media is wrongly interoperated his words and that he (probably) meant exactly opposite: that we must invest in x-risks prevention now. The media publications is only thing with which we could argue. Also I think that he may take more responsibility while talking to media, because he is guru and everything he said may be understood uncritically.
0ChristianKl6yEven the article says we have to be extra careful with x-risk prevention in the next 100 years because we don't have a self sustaining Mars base. I think you are misreading the article when you say it argues against investing in x-risk prevention now.

Comments by The Lion show up on his overview page but no longer in their original context (the permalinks say "There doesn't seem to be anything here.") What gives? In particular, that of 27 January 2016 02:16:08AM turned my inbox icon red but didn't show up in my inbox, which confused me.

2polymathwannabe6yHe has now created a new username, The Lion 2, to repost his old posts and threaten the moderators. Edited to add: As of now, he has gathered 65 karma points (87% positive) in less than a full day.
0Zubon6yThat seems like really sloppy sockpuppetry. Wouldn't that just tell admins which other accounts are likely also the same person, so ban the lot of them?
1Vaniver6yLet's not publicly discuss flaws in plans to evade admin action.
1Lumifer6yWhy not? I am not buying this argument in the context of national security, why in the world would it apply here? I didn't pinky swear to uphold the power of moderators. Besides, it's not like we're talking about non-obvious things.
0Vaniver6yThere's an asymmetry between discussing flaws in the admin's plans and discussing flaws in the attacker's plans, which is significant enough that the first can be a public service and the second a public disservice. The national security analog of the former is pointing out security holes, and the analog of the latter is giving helpful advice to terrorists. If it is truly obvious, then there is nothing to be gained by saying it; if it is not obvious, then there is something lost by saying it.
-2Lumifer6yNot quite, the defence and the attack are a matching zero-sum pair. Aiding one disadvantages the other. Pointing out security holes is routinely called "giving helpful advice to terrorists" (or other members of the unholy triad, child pornographers and drug dealers).

I silently think I have conservative political values, yet my private lifestyle is anything but. In real life, I generally expouse fairly conservative views too, in contrast to my online posting behaviours. It’s one reason I am hesistant to be completely transparent about my LessWrong/reddit identities and my every day physical world identity.

I reckon it’s okay to have different attitudes to public and private life, since governance is differant than running your own life. However, the hypocrisy kinda unnerves me. My intuition is that conservative aestheti... (read more)

1polymathwannabe6yI have liberal politics and choose to live a very restrained personal life. I don't see any incompatibility. Why do you feel hypocritical?
3gjm6yOversimplifying: * Liberals say "do what you like". If you are liberal and choose not to do X, Y, and Z then you are not violating any of your espoused principles. * Conservatives say "don't do X, Y, or Z". If you are conservative and choose to do X, Y, and Z then you are violating your espoused principles. (I repeat, the above is an oversimplification, and in fact there are things most liberals say not to do and most conservatives don't object to.)
0Strangeattractor6yIs conservatism something you appreciate aesthetically? A tribe you like belonging to more than the "liberal" tribe? Something closer or farther away from what you perceive to be reality than the alternatives? I don't know how to give advice based on the question as you've stated it. Or, rather, my advice would be to pose a better question, not necessarily here, but to yourself. Figure out where the conflicts are and evaluate each one individually, instead of generalizing to all of them.
0[anonymous]6yYes False choice. In Australia, the liberal and cosnervative tribes are one in the same for historic reasons. I'm from Australia. It's a reality of possible utilities from the value system rather than reality reality of predictive validity I'll meditate on that Ok
0Tem426yOne possible interpretation of this is that you are more liberal when surrounded by people whose judgement you trust -- which is a sane and defensible position. You should give more trustworthy (and more rational) people more leeway in their behaviors.
0[anonymous]6yI like how that sounds

Which is the best online dating site or dating app? Why?

4username26yOKCupid has way more people from geeky demographics than most other dating sites.
2Viliam6yLessWrong meetups obviously. Unless you want to date irrational people. :D
1ChristianKl6yThat likely depends on where you live and what people you are seeking. In many areas OkCupid is good because a lot of interesting people sign up for it. It's matching algorithm also allows you to search for people with similar personalities.
0CurtisSerVaas6ySurprisingly, I've had more success meeting nerdy types on Tinder than OkCupid. I think this might be because there are more people on Tinder.
0MrMind6yAre you good looking? What kind of relationship are you searching for? Where do you live?
0Brillyant6yI'm average. Monogamous. U.S. I'm looking for more of a meta analysis, though. Generally, my experience has been that ease of access is negatively correlated with the overall positivity of my experience. Pay sites seem to eliminate a lot of insincere people, where apps like Tinder (free and almost instant setup) attract many flaky people, making it almost unusable in my experience.
0MrMind6yThen I would say that your analysis is correct: in my experience, Tinder and the like are more suited to the good looking, younger and fling-searching crowd, in your case you'd be better off with Match. com and eHarmony.
0Tem426yMy experience is that pay sites are geared most towards signaling professionalism and (moderate) wealth -- which is often shorthand for 'adult', and therefore useful. However, in my experience OKCupid has provided better signaling for intelligence and thoughtfulness, simply because it allows users to write commentary on any question you answer. Most users do not take advantage of this, but looking for 'explained answers' is one of the most useful metrics I have found on any dating site.
0Gunnar_Zarncke6yThat heavily depends on your country. For Germany see here [http://www.10bestesingleboersen.de/].
2ChristianKl6yWhy do you consider that link to be good? It's a website that makes money by directing people to dating sides with affiliate programs and therefore doesn't list free websites like OkCupid or Finya. Payed websites not only mean that you pay money but also that you have people reading your messages and generally trying to manipulate you to spend money.
3Gunnar_Zarncke6yYour criticism of the linked site is valid. Nonetheless it does list the platforms with the largest number of customers. I tried Okcupid and the number of people there seems to be quite small compared to these platforms (I did like the flexible site mechanics though). Actually I will try one or two of these paid services shortly. One reason people might pay for such services is because paying signals that you are willing to invest in dating and by extension the partner. We will see.
0ChristianKl6yA while ago I sat at the community camp in Berlin where the CEO of FriendScoot24 and the CEO of ElitePartner were in attendance. That gave me an interesting perspective into how those sites work. For them it's important that you pay for the service. That means they have humans reading your messages to check that you don't give the other person your email address in the first message. They also allow you to write messages to people who can read your message but need to upgrade their account to actually read them. Apart from that I don't want to stop you from trying any of them as the invested money isn't that big compared to the possible benefit. Customers, in the sense that people pay for the service. Not customers in the sense of users. Finya has a large amount of users in Germany. On LW person recently wrote on his facebook feed that a while ago he reasoned that there were 1000 people in the world who fit his list of potential partners. Then he went on to reason that's no problem because he can actually meet those people. Multiple people I know in the German LW scene have talked about having OkCupid profiles while I don't think anybody talked about having a profile on other sites.

Mark Zuckerberg of Facebook wants to build an AI. That's a Facebook link; for anyone who for whatever reason doesn't want to go there, the Hacker News discussion includes one comment containing all Zuckerberg's text.

Oil prices have recently fallen to near record lows. What are the risks and benefits?

Risks:

  • Increased instability in the Mideast as governments are less able to buy the loyalty of the people.
  • Likely slow the transition to electric vehicles, may slow the overall decline of carbon emissions.
  • Many job losses in petroleum-producing locations, especially higher cost producers.

Benefits:

  • Possibly stimulate the global economy, especially good for fast-developing oil importers like China and India.
  • Might push oil producers toward economic reforms that will b

2MrMind6yOnly two nuances: * Venezuela is / will very shortly also experience political instability; * Iran has just seen heavy international sanctions lifted, so while its oil will be valued less than it could have been, it will still provide a push to the economy.
0[anonymous]6yFinally my readings of Stratfor Wikileak documents about Venezuala are topical!
1_rpd6yWe can expect lower food prices. High food prices have been an important political stressor in developing nations.
0RichardKennaway6ySaudi Arabia flooded the market in order to reduce the price, in order to combat the benefit to Iran of the raising of sanctions.
3ChristianKl6yTheir oil production didn't rise that much. They didn't really flood the market. They mainly decided not to cut their production.
0_rpd6yAnd there is a good reason for this decision. Saudi Arabia tried cutting production in the '80s to lift prices, and it was disastrous for them. Here's a blog post with nice graphs showing what happened ... Understanding Saudi Oil Policy: The Lessons of ‘79 [http://www.prienga.com/blog/2014/11/11/understanding-saudi-oil-policy-the-lessons-of-79]
0knb6yThat's one argument. Another common argument is that they want to increase their market share and kill the US tight oil industry.
0polymathwannabe6yThat's a strange move. Right now the last thing oil producers need is even lower prices.
2Lumifer6yYou're assuming they are maximizing money. That is not so.
0MrMind6yConsider that Saudi Arabia and Iran are on the opposing side of Islam sects, so the reason was to stump the sudden economic growth of their enemy. Yes, it's centuries that people kill each over who was the correct successor of Muhammad, his cousin or his friend. Welcome to planet Earth...
0polymathwannabe6yI get that. But by cutting their own lifeblood? On what basis do Saudi strategists estimate that the damage to the Saudi economy will be small enough compared to the damage to the Iranian one?

I would love to see a CFAR SuperBetter pack.

Why does my Karma score keep increasing when I don't do anything? It's a disincentive to post. . .?

2tut6yPresumably people read your old comments and upvote them.
0Dagon6yI think tut has it right: old articles still get some votes. But why is it a disincentive? I'd think it would make you (slightly) more willing to take a risk and post something that might get downvoted, since you don't expect a marginal downvote to matter as much based on your background karma income.
1gjm6yI think WhyAsk's model of the situation was "get karma while not doing anything" rather than "get karma independently of what you're doing". (WhyAsk, the reality is much nearer the latter than the former.)
0WhyAsk6yA lot of what I was sure of, I'm not any longer. . .:D

Why isn't there empirical evidence in the Wikipedia article on investment strategy? Are the hypothesises financial engineers make unscientific?

3IlyaShpitser6yMarkets are not like Nature, they are much more adversarial.
0[anonymous]6yEven if they are better modeled by game theoretic processes, surely that could still be inferred empirically?
5IlyaShpitser6yI don't know what you mean by "inferred empirically." If you mean "statistical inference," there are tons of unstated assumptions that basically assume the observed object is benign or indifferent. There is work in machine learning on learning in adversarial settings, but it's a much harder problem. Markets are super adversarial, and in addition there are incentives against publishing sensible analyses (why give away money to hostile/competing interests?) -------------------------------------------------------------------------------- edit: Sorry, I should say "tons of assumptions." People state them, and it's clear they are benign, e.g. samples are i.i.d.
2[anonymous]6yHow interesting! I've seen work on game theoretic optimal poker playing. I can only imagine how sophisticated the market versions would be. Looking forward to seeing a wikipedia page on the topic one day :)
1ChristianKl6yPoker is a game with known rules. In investing the rules are not known in the same way. Nassim Taleb calls equating the two the ludic fallacy.
0[anonymous]6yWho?
3gjm6yNassim Nicholas Taleb [https://en.wikipedia.org/wiki/Nassim_Nicholas_Taleb], author of the somewhat well-known book "The Black Swan". Former (successful) trader and (not so successful) hedge fund manager.
0[anonymous]6yInteresting!
0Lumifer6yDepends on your definition of "scientific". Markets change. What used to be true ten years ago might not be true now.
0ChristianKl6yIn this case it seems to mean "What Wikipedia considers scientific enough to back up a claim".
0[anonymous]6yNature changes too. In both cases I believe there are identified causal determinants of both market and natural behaviour and in both cases these can change over time. Still, the scientific process can be meta-inducted in the case of markets to identify whether, for instance, financial news or academic papers give useful tips and in what circumstances. In fact, now I'm really curious to know about literature on that very topic.

Cost of being less wrong: increased cognitive load?

Benefit oblw: longer life expectancy?

Risk oblw: becoming a pariah in most crowds?

3username26yFinding a crowd that allows your abilities to bloom is a useful skill as well :)
0WhyAsk6yThat's one reason I'm here, but in the limited time the mortality tables give me I'd like to find a way to present myself favorably to almost any crowd. In the past, very few have cheered me on and a more vocal few have fervently hoped I'd fail.
2TimS6yThere's no reason you should be a pariah accidentally simply because you have clarified your goals or gotten better at implementing them. One possibility - your estimate of how many people are not friends to you. That sucks, but you can't force another person to be a good person at you. Remember the right way to approach someone-is-wrong-on-the-internet, and apply the same principle to in-person interactions. This is a much harder, and dramatically different goal, from not being a pariah.
0PipFoweraker6yThere is value in having crowds that view you mildly and strongly disfavourably, but much of this value depends on the rule of law in one's immediate environment.
1[anonymous]6yI was very inefficient when I was more wrong. Definately lower cognitive load now.
0[anonymous]6yCost: Not much that I wasn't already doing, less optimally. Benefit: Social group that I can count on to at least TRY to be epistemically honest. Also, openness towards odd people. Risk: Pariah? I'm already considered odd by a lot of people.
0WhyAsk6y:D The textbooks written about my personality type say I'm "eccentric".
