27 hours to PhD thesis submission. Science is hard.

EDIT first allnighter in a long time.

1username24yI'm rooting for you!
1CellBioGuy4yIt is in! Now 2 days to put together final edits for my committee, 2 weeks to seminar/defense, and then a week or so for final revisions... interesting to see 6 years in 133 pages.

This feels quite important, especially in the context of "dying Less Wrong":

Bottom line: I know of only one minimum viable architecture for turning individuals into a superorganism — for making sure it’s in everyone’s self-interest to work together. I call it the Prestige Economy, and it runs on a deceptively simple rule:

Individuals should grant social status to others for advancing the superorganism’s goals.

-- source

1MrMind4yHow is this different from the karma system?
3Viliam4yKarma system itself doesn't specify what you get most karma for. It could be "for advancing the superorganism’s goals", but it also could be for "making snarky comments about those who try to advance the superorganism’s goals", or simply for "posting a lot of trivial stuff". Also, social status is perceived not only by how much karma one has, but also how they are treated (replied to, talked about) by other people in comments.
0MrMind4yIndeed, but how would you enforce a system of points granted if and only if someone advances the goal of this site? This I think is unavoidable in a human society.
0Viliam4ySometimes what would be easier to do in real life is more difficult to do online, because the functionality is different or missing. For example, the real-life equivalent of "karma" -- displays of admiration or friendship -- is public. Assuming voluntary association, one way to "enforce a given behavior" is to only associate with people who agree to behave like that. So if you want to have a group that does X, you associate with people who give social status to people working on X (as opposed to e.g. people who talk a lot about X, but give low status to people actually working on X). Online... I guess banning people for not expressing proper attitudes would be perceived by many as very problematic (even if that's what most of us more or less do in real life), so the realistic solution seems to be an invite-only club. Or a two-tiered system, where the outer forum is open to everyone, and only people with the desired behavior get an invitation to the inner forum.
0Lumifer4yYou are glossing over the practice of giving social status. In real life, as you said, it is basically public displays of admiration (friendship is a bit different). So you are going to build a community with the inclusion criterion of being willing to publicly admire a particular set of people. Presumably if you stop admiring, you are no longer welcome in the community. That doesn't strike me as a way to build a healthy community -- there are obvious failure modes looming.
1gjm4yThat isn't quite what Viliam is proposing. He says (emphasis mine): so what membership in this community commits you to is not admiring specific people but admiring people who do specific things, whoever those people are. This still seems kinda dangerous, but I don't think it has the same failure modes.
0Lumifer4yI suspect that distinction is not going to be as clear-cut when you are dealing with a bunch of actual humans. "Bob is an asshole but he did the specific thing X so I'm supposed to publicly praise him? I'll pass." "Alice is such a great person, so what that she skipped the specific thing X this time, she's the best and I'm going to sing hosannas to her really loudly".
0philh4yYou seem to have hit on (one reason) why the prestige economy is different from the karma system.
0MrMind4yNo, my question was more abstract, in the sense of "can you ever design a system that grants a prestige economy that doesn't de-evolve into a karma system"?
0username24yKarma is not granting social status, it is community moderation of discussion. Imagine if the aggregate karma numbers were removed from display (arguably this is maybe something that should be done).
0MrMind4yKarma was not designed to grant social status, but people look at it as if it does.
1Lumifer4y"Individuals should" is not an architecture. A great many things become possible conditional on "everyone should so as I say".
0Viliam4ySure, but assuming you have people willing to contribute to "many things", it can help to say explicitly what behavior is helpful and what is harmful. Especially among nerds.
0tristanm4yWhat do you think is the best example of this kind of principle at work? My first guess would be academia, but I can also think of a dozen reasons why the prestige system in academia is flawed. My intuition is that there is really no shining example of the prestige economy in the real world - but whether this has to do with the difficulty of implementation, or a flaw with the idea itself, I'm not sure.
0Viliam4yThere can be many flaws in implementation, and we probably won't find a perfect one, but academia seems like a decent example. It has a goal (research and education), and it assigns status (academic functions) to people who contribute to that goal, and the status comes with certain benefits (salary) and powers (over students) which means other people will recognize it as a status. If you spend a lot of time hanging out with professors and learn all their buzzwords, but you will do no research nor teaching, you are not going to become a professor, i.e. you are not able to out-status them within the academia. Another example would be meritocratic open-source projects, where people are respected according to their contributions to the project. Or perhaps a sales department, where people are rewarded depending on their sales.
0Lumifer4yHow is that different from pretty much any job? Let's take ditch-digging. It has a goal (digging ditches), and it assigns status (becoming a foreman, then a manager) to people who contribute to that goal, and the status comes with certain benefits (salary) and powers (over workers) which means other people will recognize it as a status. If you spend a lot of time hanging out with ditch-diggers and learn all their buzzwords, but you will do no digging of ditches, you are not going to become a ditch-digger, i.e. you are not able to out-status them within the ditch-digging world.
2gjm4yI don't think anyone was claiming it doesn't apply to pretty much any job. (In the original context, the point was that it does apply to pretty much any job, and to a host of other things besides.) It will apply better to some jobs than others. It needs * the people doing that job to form a community in which social status is actually meaningful * mere membership of the community to be seen by its members as conferring status * doing the job effectively to lead to promotion to a position in which one can do it better * (preferably) status within that community to have some currency elsewhere. Those are all true for academia. There is definitely such a thing as the academic community, its members relate to one another socially as well as professionally, academics tend to think highly of themselves as a group, promotion means better opportunities for furthering academic research (oneself or by organizing subordinates and taking some credit for their work), and -- at least in the nice middle-class circles in which academics tend to move -- there's some broader cachet to being, say, a professor. I think they're less true for ditch-digging. So far as I know, there isn't the same sort of widely-spread confraternity of ditch-diggers that there is of academics. I've not heard that ditch-diggers see themselves as having higher status than non-ditch-diggers. I think a lot of ditch-diggers are casual labourers with no real prospects of promotion, though I confess I don't exactly have my finger on the pulse of ditch-digging career progression. And there are few social circles in which introducing yourself as a ditch-digger will make people look up to you. So yeah, this structure applies to things other than academia, but it does seem like it applies better to academia than to the other example you offered.
0Lumifer4yWe could swing in the other direction and consider hedge fund managers instead of ditch-diggers if you worry that ditch-diggers are too low status :-) However I think the issue is a bit different. The original question was how to build a community successfully driven by status. Once we switch to jobs we are talking about money and power -- pure status becomes secondary. Besides, academia seems to me to be a poor example. Its parts where advancement doesn't give you much in the way of money and power -- that is, social sciences -- became quite dysfunctional and the chasing of status leads to bad things like an ever-growing pile of shit research being published as "science".
0gjm4yPossibly, though I suspect status is more important relative to money in motivating employees than is commonly thought. I'm not sure you get a lot more money and power from advancement in other areas of academia. (Unless you count coaching the football team, in US universities. Plenty of money there.) It seems to me that there are better explanations if the hard sciences are less dysfunctional than the soft. Whether things like are evidence that the academic community isn't driven successfully (whether by status or by something else) depends on what you take to be the actual goals of academia as an institution. I agree that if we take those goals to be research that actually uncovers truths, and education that actually improves the minds and the lives of the educated, it's debatable how well academia does.
0Lumifer4yI think power is more important than commonly thought, but I accept that it's not easy to disentangle it from status. You do in some, notably law and business. And yes, I'm not saying that's the main explanation why soft sciences do so much worse than hard ones.
0Viliam4yI have no experience with professional ditch-digging, so I can't comment on that. My job experience is mostly software development, and in many companies the people who actually create the software are near the bottom of the status ladder. (Which I guess is okay, because the actual goal is making money; creating quality software is just an instrumental goal which can be sacrificied for the higher goals at any moment.)
0ChristianKl4yI'm not sure that "social status" on an online forum like this is an important currency.
0WhySpace_duplicate0.92616921290755274yAwesome link, and a fantastic way of thinking about how human institutions/movements/subcultures work in the abstract. I'm not sure the quote conveys the full force of the argument out of that context though, so I recommend reading the full thing if the quote doesn't ring true with you (or even if it does).
0Elo4yLesswrong doesn't celebrate heroes much. I think that's on purpose though...
1Viliam4yYes, but... []
0ChristianKl4yI feel like has the problem but our local LW Berlin community doesn't.
0WhySpace_duplicate0.92616921290755274yTrue. Maybe we could still make celebrate our minor celebrities more, along with just individual good work, to avoid orbiting too much around any one person. I don't know what the optimum incentive gradient is between small steps and huge accomplishments. However, I suspect that on the margin more positive reinforcement is better along the entire length, at least for getting more content. (There are also benefits to adversarial review [] and what not, but I think we're already plenty good at nitpicking, so positive reinforcement is what needs the most attention. It could even help generate more long thoughtful counterarguments, and so help with the better adversarial review, improving the dialectic.)
2Viliam4yThis. Different people need different advice. People prone to worship and groupthink need to be told about the dangers of following the herd. People prone to nitpicking and contrarianism need to be told about how much power they lose by being unable to cooperate. Unfortunately, in real life most people will choose exactly the opposite message -- the groupthinkers will remind themselves of the dangers of disagreement, and the nitpickers will remind themselves of the dangers of agreement.

I must admit to some amount of silliness – the first thought I had upon stumbling onto LessWrong, some time ago, was: “wait, if probability does not exist in the territory, and we want to optimize the map to fit the territory, then shouldn’t we construct non-probabilistic maps?” Indeed, if we actually wanted our map to fit the territory, then we would not allow it to contain uncertainty – better some small chance of having the right map, then no chance, right? Of course, in actuality, we don’t believe that (p with x probability) with probability 1. We do n... (read more)

1WhySpace_duplicate0.92616921290755274yI rather like this way of thinking. Clever intuition pump. Hmmm, I guess we're optimizing out meta-map to produce accurate maps. It's mental cartography, I guess. I like that name for it. So, Occam's Razor and formal logic are great tools of philosophical cartographers. Scientists sometimes need a sharper instrument, so they crafted Solomonoff induction and Bayes' theorem. Formal logic being a special case of Bayesian updating, where only p=0 and p=1 values are allowed. There are third alternatives, though. Instead of binary Boolean logic [], where everything most be true or false, it might be useful to use a 3rd value for "undefined". This is three-value logic [], or more informally, Logical Positivism []. You can add more and more values, and assign them to whatever you like. At the extreme is Fuzzy Logic [], where statements can have any truth value between 0 and 1. Apparently there's also something which Bayes is just a special case of, but I can't recall the name. Of all these possible mental cartography tools though, Bayes seems to be the most versatile. I'm only dimly aware of the ones I mentioned, and probably explained them a little wrong. Anyone care to share thoughts on these, or share others they may know? Has anyone tried to build a complete ontology out of them the way Eliezer did with Bayes? Are there other strong metaphysical theories from philosophy which don't have a formal mathematical corollary (yet)?
1Houshalter4yI think a concrete example is good for explaining this concept. Imagine you flip a coin and then put your hand over it before looking. The state of the coin is already fixed on one value. There is no probability or randomness involved in the real world now. The uncertainty of it's value is entirely in your head.
1Viliam4ySure; including probability in the map means admitting that it is a map (or a meta-map as you called it).

I was thinking of how we could decrease the barriers to presenting ideas on LW.

Personally, when I think about writing something up here, I feel an unusually high need to make it high quality. That has the obvious benefit of encouraging people to make better stuff, but I've also felt it play out such that I just don't bother presenting.

How about a weekly thread for people to present 100-word half-baked, half-polished ideas explicitly for the purpose of seeing if people would like there to be something more substantial on the subject submitted to LW discussi... (read more)

3ChristianKl4yI don't think there's anything wrong with having an additional thread like this. But there no need to commit to a weekly schedule from the beginning. Simply open one and then see how it goes. MVP's.
0MrMind4yHow about a [stub] tag in the title?
0Bound_up4yWhat is that, exactly?
0MrMind4ySimply prefix the word [stub] to the title of the article, and add the word 'stub' to the tags. The code doesn't allow for formal tags in the title, so it's a custom here that whatever sits at the beginning of the title and between square brackets is metadata.
0MaryCh4y...maybe bi-weekly?

Quixey has been shutdown.

3Daniel_Burfoot4ySorry to hear that, I know a lot of LW-adjacent people were involved. Is there a postmortem discussion or blog post anywhere?

I wrote an article, but was unable to submit it to discussion, despite trying several times. It only shows up in my drafts. Why is this, and how do I post it publicly? Sorry, I'm new here, at least so far as having an account goes - I've been a lurker for quite some time and have read the sequences.

1Elo4yBelow the edit area is a drop down menu where you can select "discussion", you may need 10 karma to post it.
1I_D_Sparse4yAh, thanks. Uh, this may be a stupid question, but how do I upvote?
1Elo4yAt the bottom left of each post or comment is a thumb up button
3I_D_Sparse4yI don't see it... do you need a certain amount of karma to vote?
2g_pepper4yYes, my understanding is that you need a certain number of karma points to vote. I think the number is 10, but I am not certain of this.
0Elo4yHave you verified your email address?
0Viliam4yYou have 10 karma now; act quickly! :D :D :D

TAP's (Trigger Action Plans) have become increasingly ubiquitous in the LW consciousness (my impression).

Does anybody have some cool TAP's they'd like to share? Should we have a depository of good ones?

I've set up a few:

IF back hurts, THEN adjust posture (right now, that's mostly focusing on the angle of my hands as they swing and the angle of my spine to my hips)

IF notice procrastination/have the "I should really do XYZ...." feeling, THEN take five mindful breaths.

4MrMind4yIF acquiring a new belief, THEN try to destroy it immediately. An example from yesterday: "wow, these TRX suspension trainer look really cool, they would allow me to do better pull-ups", following immediately by "I should read negative reviews of TRX right now."
1Elo4yIf organising some event, put it in my diary now. (if people say, "we should catch up") When I get home I put my laptop on my desk and plug it in.

Do people study effects of drugs (that wouldn't lead to crippling or fatal outcomes) on healthy people? (Stupid question, just, the latest post on SSC, on pharmacogenomics, made me wonder about it. Could be nice to have a baseline.)

3sixes_and_sevens4yPhase I clinical trials [] exist for this purpose. The objective of Phase I trials is to establish safety, dosage, and side-effects of drugs in human subjects, and to observe their proposed mechanism of action if relevant. It's rare for Phase II and III trials (which have clinically-relevant endpoints [] ) to be carried out on healthy subjects. Part of this is ethical considerations, but also clinical trials are extremely expensive to carry out, and there's not much payoff in learning whether your drug has some specific effect on healthy subjects.

Writing Scifi: Seeking Help with a Founding Charter

I'm trying to figure out which details I need to keep in mind for the founding charter of a particular group in a science-fiction story I'm writing.

The sci-fi bit: The group is made up of copies of a single person. (AIs based on a scan of a human brain, to be precise.)

For example, two copies may have an honest disagreement about how to interpret the terms of an agreement, so having previously arranged for a full-fledged dispute-resolution mechanism would be to the benefit of all the copies. As would guidel... (read more)

1MrMind4yAre the personalities of the sub-copies allowed to evolve on their own? If this is true, given enough time there would be very little difference between a society of people following from the same source and a society of individual that were born from different parents, so you would require no special treatment of the subject.
1DataPacRat4yYes, the copies are expected to diverge to that degree, given sufficient time. However, by the time that happens, enough evidence about organizational science will have been gathered for the founding charter to have been amended into unrecognizability. That's not the period of development I'm currently focusing on. If by 'no special treatment' you mean 'an existing co-op's charter and by-laws could be copied, have the names search-and-replaced, and they'd be good to go', I disagree; the fact that the copies can make further copies of themselves, and that the copies can be run at extremely different speeds, adds a number of wrinkles to such topics as defining criminal responsibility, inheritance, and political representation, just for starters. That said, I'm perfectly willing to save myself as much effort as is possible by importing any existing pieces of charters or bylaws which don't need further tweaking, if anyone can point me to such.
0MrMind4yWell, if this charter is important for the story, then you should tweak the future organizational science so that it points in the direction you want to. If otherwise it's not, then why not hand-wave it?
2DataPacRat4yJust because I don't currently know the details of the relevant bits of organizational science doesn't mean somebody around here doesn't already know them. Just because I can't do the math as easily as I could for rocket science is no excuse to try to cheat how reality functions.
0MrMind4yThat is an objection that is only valid for a story happening in a time near to us. But, as you say: and nobody out there can possibly know their own field hundreds of years in the future. I state my case: handwave everything and concentrate on the story.
0DataPacRat4yI believe I may have phrased that quoted part poorly. Perhaps, "... long before the time the copies diverge enough to want to split into completely separate groups, they would likely have already learned enough about the current state-of-the-art of organizational theory to have amended the charter from its initial, preliminary form into something quite different". I didn't mean to imply 'hundreds of years', just a set of individuals learning about a field previously outside their area of expertise.
0MrMind4yI still don't understand why it has to be a charter instead of, say, an AI that can react to change and update itself on new information.
0DataPacRat4yBecause I am actually reasonably capable of creating some sort of actual charter that actually exists, and apply it to a scenario based on minor extrapolations of existing technologies that don't require particularly fundamental breakthroughs (ie: increased computer power; increased understanding of how neural cells work, such as is being fiddled with in the OpenWorm project; and increased resolution of certain scanning technology). I wouldn't know where to begin in even vaguely describing "an AI that can react to change and update itself on new information", and if such a thing /could/ be written, it would nigh-certainly completely derail the entire scenario and make the multi-self charter completely irrelevant.
0MrMind4yI'm just saying that a coordinating AI seems an obvious evolution, I was told just yesterday by one of my coworker that machine learning systems for the automatic checking of complex regulations are already used profitably. Anyway, if the charter itself is the focal point of the story, by all mean delve into organizational science. Just don't forget that, when writing science fiction, it's very easy to descend into info-dumping.
0DataPacRat4yI've been skimming some of my setting-idea notes, such as 'algorithms replacing middle-managers' and have realized that, for a certain point of the planned setting, you've highlighted an approach that is likely to be common among many other people. However, one of the main reasons for my protagonist's choice to try relying on himselves is that AIs which optimize for various easy-to-check metrics, such as profitability, tend not to take into account that human values are complex. So there are likely going to be all manner of hyper-efficient, software-managed organizations who, in a straight fight, could out-organize my protagonist's little personal co-op. Various copies of my protagonist, seeing the data, will conclude that the costs are worth the benefits, and leave the co-op to gain the benefits of said organizational methods. However, this will cause a sort of social 'evaporative cooling', so that the copies who remain in the co-op will tend to be the ones most dedicated to working towards the full complexity of their values. As long as they can avoid going completely bankrupt - in other words, as long as there's enough income to pay for the hardware to run at least one copy that remains a member - then the co-op will be able to quietly chug along doing its own thing while wider society changes in various values-simplifying ways around it. ... That is, if I can do everything that such a story needs to get done right.
0moridinamael4yIn lieu of coming up with a creative solution to your problem, I will relate how Hannu Rajaniemi solves this problem in the Quantum Thief [] books, particular for the group called the Sobornost. (Spoilers, obviously.) There are billions (trillions?) of copies of certain individuals, and each copy retains self-copying rights. Each copy knows which agent forked it (who its "copyfather" is), and is programmed to feel "religious awe" and devotion to its specific line of descent. So if you found yourself spawned in this world, you would feel strong awe and obedience for your copyfather, even stronger awe and obedience for your copygrandfather, and ultimate devotion to the "original" digital version of yourself (the "prime"). This policy keeps everyone in line and assists in conflict resolution, because there's always a hierarchy of authority among the copies. This also allows small groups of copies to go off and pursue a tangential agenda with trust that the agenda will be in line with what the prime individual wanted.
0DataPacRat4yIt's an interesting solution, but the ability to edit the AIs to reliably feel such emotions is rather further in the future than I want to focus on; I want to start out by assuming that the brain-emulations are brute-force black-box emulations of low-level neural processes, and that it'll take a significant amount of research to get beyond that stage to create more subtle effects. That said, I /do/ have some notes on the benefits of keeping careful track of which copies "descend" from which, in order to have a well-understood hierarchy to default back onto in case some emergency requires such organization. I've even considered having 'elder' copies use a set of computational tricks to have kill-switches for their 'descendants'. But having spent some time thinking about this approach, I suspect that an AI-clan which relied on such a rigid hierarchy for organizing their management structure would be rapidly out-competed by AI-clans that applied post-paleolithic ideas on the matter. (But the effort spent thinking about the hierarchy isn't wasted, as it can still serve as the default basis for legal inheritance should one copy die, and as a default hierarchy in lifeboat situations with limited resources of the AI-clan hasn't come up with a better system by then.)
0TimS4yI suspect your proposed charter is practically impossible for you to write. If is was possible for one charter document to scale up and down the way you suggest, then we should expect it to already exist and be in use. After all, people have been writing charter documents for a long time. In the real world, charter don't survive in their original form all that long. To pick an example I am familiar with, the US Constitution was ratified in 1789. Fourteen years later, in 1803, the Supreme Court interpreted the document to allow judicial review of whether statutes complied with the Constitution. You'll have to take my word for it, but whether judicial review was intended by the drafters of the US Constitution is controversial to this day. It is pretty clear that the drafters would have been surprised by the degree of judicial intrusiveness in implementing policy, just as they would be surprised by how much the US has grown in economic size and political power since the Constitution was drafted.
0DataPacRat4yIf we're going for American political parallels, then I'm trying to put together something that may be more closely akin to the Articles of Confederation; they may have been replaced with another document, but their Articles' details were still important to history. For a more modern parallel, startup companies may reincorporate at various times during their spin-ups and expansions, but a lot of time they wouldn't need to if they'd done competent draftwork at the get-go. Amendment, even unto outright replacement, is an acknowledged fact-of-life here; but the Founder Effect [] of the original design can still have significant consequences, and in this case, I believe it's worth doing the work to try to nudge such long-term effects. That said - in the unlikely event that it turns out to be impossible to assemble a charter and bylaws that do everything I want, then I can at least put together something that's roughly equivalent to the Old Testament [] in the sense of being "a stream-of-consciousness culture dump: history, law, moral parables, and yes, models of how the universe works", to serve as enough of a foundational document to allow the AI copies to maintain a cohesive subculture in much the way that Rabbinical Judaism has over the centuries.
0TimS4yThe Articles of Confederation were not amended into the Constitution, they were replaced by the Constitution in a manner that likely violated the Articles. Likewise, the Old Testament leads to Priestly Judaism (with animal sacrifice), not the radically different Rabbinical Judaism. I think trying to bring these things in parallel with start-up incorporation is inherently difficult. Re-incorporation of start-ups is driven by the needs of mostly the same stackholders as the original incorporation. Most importantly, they are trying to achieve the same purpose as the original incorporation - wealth to founders and/or investors. Changes to foundational governing documents are usually aimed at changed or unanticipated circumstances, where the founders's original purpose does not address how the problem should be solved.

I said a few weeks back that I would publically precommit to going a week without politics. Well, I partially succeeded, in that I did start reading for example an SSC article on politics because it popped up in my RSS feed, but I stopped when I remembered that I was ignoring politics. The main thing is I managed to avoid any long timewasting sessions of reading about politics on the net. And I think this has partially broken some bad habits of compulsive web browsing I was developing.

So next I think I shall avoid all stupid politics for a month. No facebo... (read more)

0Lumifer4yThat applies to homosexuality in spades, and yet gay people haven't been washed out of populations. By the way, keep in mind that "feminist" is not a very precise label. In particular, there is a rather large difference between the first-wave feminists (e.g. Camille Paglia) and third-wave feminists (e.g. Lena Dunham, I guess?). They don't like each other at all.
0Elo4ythere was a theory that the genes that confer gay men also confer extra fertility for women (and twinning). So keeping the genes in the population via other mechanisms. (I think the research was in Italian families, no link sorry.)
2gwern4yAside from the inclusive fitness claim, Cochran's gay germ hypothesis is also consistent with the continued existence of homosexuality: the pathogen co-evolves and so while the genes do get selected against, which genes keeps changing. Unfortunately, his theory still remains something of a 'germ of the gaps' theory - no one's come up with a remotely plausible theory or found decent evidence that homosexuality spikes the fertility of relatives so much as to compensate for the sterility of homosexuals (remember, inclusive fitness decreases fast: if a homosexual has 1.05 rather than 2.1 children, then their siblings have to have 2.1 additional children, their cousins 4.2 additional children, and so on), so a theory which merely isn't contradicted by any evidence looks pretty good by comparison. One thing I thought of which would be direct evidence for the infection theory: polygenic scores for homosexuality. It's somewhat heritable, so given a large sample size like UK Biobank, it should be possible to explain a few % of variance and construct a PGS based on a fairly narrow age cohort like 1 or 2 decades. Then the PGS can be applied longitudinally outside the sample. If it's pathogenic co-evolution and the relevant genes keep changing, then the homosexuality PGS should show highest predictive validity in the original age bracket, but then decrease steadily as one moves away from the age bracket into the past or toward the present, showing a clear inverted V shape. While polygenic scores can increase or decrease steadily or show sudden shocks for various reasons just like heritabilities can increase/decrease over time (eg education PGS decrease due to dysgenics, height PGS increase and so on), they don't typically show a distinct V shape, so finding one for homosexuality would be very striking.
1Mitchell_Porter4yMy theory and meta-theory: The gay germ theory is pretty silly. But the big myth to which it is a reaction, is the idea that people are simply "born that way". Cochran has a paranoid intuition that something else is happening, so he posits his gay germ. But what's really happening is sexual imprinting. A person's sexuality is greatly shaped by the first conditions under which they experience arousal, orgasm, and emotional bonding. Sexualities are "transmitted" in a way a little like languages. There's no "German germ" which makes people think and speak auf deutsch, instead there's some sort of deep learning based on early experience of a German-speaking environment. The acquisition of sexuality might be more like conditioning than learning, but it's still an acquired trait.
3gwern4yThat theory is even worse than the inclusive fitness one because you offer no mechanism whatsoever to offset the huge fitness penalty. Sexual imprinting is a highly successful evolved mechanism critical to reproductive fitness which does in fact succeed in the overwhelming majority of cases; in many ways, it is more important than trivial details like 'eating food' because at least an offspring which immediately starves to death doesn't drain parental resources and compete with siblings and the parents can try again! There should be a very good reason why such an important thing, found throughout the animal kingdom in far stupider & less sexually-dimorphic organisms, goes wrong in such a consistent way when other complex behaviors work at a higher rate and fail much more bluntly & chaotically. 'Random imprinting' is too weak a mechanism to thwart such a critical device, and doesn't explain why the errors do not rapidly disappear with general or sex-linked adaptations. (Even as a 5% liability-threshold [] binary trait, a reproductive fitness penalty of 50%, to be generous to a trait which involves active aversion to procreative sex, would imply it should be far lower now than when it first arose*.) Further, such a random nonshared environment theory doesn't explain why dizygotic and monozygotic same-sex twins differ in concordance. (They don't differ in language, so your example is evidence against your imprinting theory.) * [] gives a low end heritability estimate of 0.31; population prevalence among males is usually estimated ~5% giving a liability threshold of ~-1.64; homosexuality is amply documented fo
0Mitchell_Porter4yMy guess is that it's somehow a spandrel of intelligence.
0gwern4yTo be immune to selection because it's part of intelligence would imply a strong genetic correlation []. Aside from the fact that I am doubtful any such genetic correlation will ever be found (there is no noted phenotypic correlation of homosexuality & intelligence that I've heard of), this still has the issue that homosexuality ought to be decreasing noticeably over time: while intelligence has apparently been neutral or selected for over the past few millennia and so hypothetically could've slowed the selection against homosexuality, intelligence itself has been selected against for at least a century, so that would accelerate the selection now that there are fitness penalties for both homosexuality & intelligence (by a fair bit, because selection on continuous traits is much faster than selection on rare binary traits).
0Douglas_Knight4yI've heard the raw correlation widely claimed, but I think most people interpret it as measuring closeting. Certainly openly gay men have higher income than straight men.
0Error4yI'd be inclined to suspect closeting too. The better your ability to support yourself, the less you need to worry about repercussions. Tangential and possibly relevant: I've noticed bisexual women appear to be ridiculously common in high-intelligence nerd communities. I don't know whether I should associate that with the intelligence or the geek/nerd/dork personality cluster, nor do I know which way the causation goes.
1Douglas_Knight4yYou only posit that because your paranoid ignorance of biology. Bullshit. Cochran wrote down his exact thought process [] . He thinks that everything is due to germs. Moreover, he measures of the strength of the evidence. Schizophrenia and (male) homosexuality are at the top of the list
1Mitchell_Porter4yOK, let's talk about proximate causes and ultimate causes. The proximate causes are whatever leads to the formation of a particular human individual's sexuality. The ultimate causes are whatever it is that brought about the existence of a population of organisms in which a given sexuality is even possible. My focus has been on proximate causes. I look at the role of fantasy, choice, and culture in shaping what a person seeks and what they can obtain, and the powerful conditioning effect of emotional and sexual reward once obtained, and I see no need at all to posit an extra category of cause, in order to explain the existence of homosexuality. It's just how some people end up satisfying their emotional and sexual drives. What I had not grasped, is that the idea of the gay germ is being motivated by consideration of ultimate causes - all this talk of fitness penalties and failure to reproduce. I guess I thought Cochran was a science-jock who couldn't imagine being gay, and who therefore sought to explain it as resulting from an intruding perturbation of human nature. I am frankly not sure how seriously I should take the argument that there has to be (in gwern's words) a "mechanism... to offset the huge fitness penalty". Humanity evolves through sexual selection, right? And there are lots of losers in every generation. Apparently that's part of our evolutionary "business model". Meanwhile I've argued that non-reproducing homosexuality is a human variation that arises quite easily, given our overall cognitive ensemble. So maybe natural selection has neither a clear incentive to eliminate it, nor a clear target to aim at anyway.
0entirelyuseless4yI agree with what you said, and it is borne out very well by my experience of gay persons. As for gwern's comment, the silliness is to think that evolution has enough selective power to completely remove that sort of thing. In fact, it would be far easier for evolution to remove a gay gene than for it to prevent things that happen through accidental social circumstances. Consider this: I am over 40, I do not have children and have never had sex, and I have no intention to do so. Shouldn't evolution have completely removed the possibility of people like me? I am not even helping other people raise children. I live alone, and consume my own resources. The answer is that if "people like me" came about because of a specific gene, evolution would indeed have removed the possibility. As it is, it comes about through a vast collection of accidental and social facts, and the most evolution can do is make it rare, which it does. The same is true of homosexuality.
0Douglas_Knight4yWhereas you can imagine it so easily that you didn't bother to look at the real world, just as you can imagine Cochran so easily you didn't bother to look at him 90% of biologists don't believe in evolution, either, but progress comes from those who do.
0Mitchell_Porter4yI believe in evolution, I just don't believe in the gay germ. But regardless of belief... I have some questions which I think are fair questions. Are there any ideas about how and when the gay germ is acquired? Are there any ideas about its mechanism of action? If homosexuality has such a huge fitness penalty, why haven't we evolved immunity to the gay germ? If someone hasn't experienced sex yet, but they already think they are gay, is that because of the gay germ?
0Douglas_Knight4yGays generally say that they "always knew they were different" (and there is some evidence that this is not just confabulated memories), so it is probably acquired before age 5, possibly before birth. It is probably something common, like the flu. And there might be multiple infections that cause the same brain changes, as appears to be the case with narcolepsy. You could ask a similar question about any explanation of homosexuality. It is measured to be weakly heritable. So we know that there are genes that protect from it. Given the fitness penalty, why haven't those genes swept through the population? That wouldn't necessarily eliminate it, but they would eliminate the heritability. There are only two possibilities: either the fitness penalty is not what it looks like (eg, the sexual antagonism hypothesis); or the environment has changed so that which genes protect has changed. Germ theory gives a simple explanation for changing environment, The Red Queen Hypothesis: the germ is evolving, so the genes that protect against it are changing. This is the metric that Cochran and Ewald use: multiply the fitness cost by the heritability. The higher that number, the more likely the cause is infection.
0Mitchell_Porter4yThere actually is a known replicator that assists the reproduction of gay phenotypes, but it's a behavior: gay sex! For a recent exposition, see the video that cost "Milo" his job.
0Douglas_Knight4yNo, there is no evidence of such replication. This isn't really compatible with gays being detectable at age <5. Also, it's pretty clear that isn't what happens in sheep, which are highly analogous. Common infections can have effects on a small population. For example, Barr-Epstein is implicated in at least some cases of narcolepsy, but 95% of the population tests positive for it.
0Mitchell_Porter4yWhat about pederasty in ancient Greece, what about sex in all-male prisons... in both those cases, you have men who by current definitions are not gay, but rather bisexual. And in both cases you have recruitment into an existing sexual culture, whether through seduction or coercion. Human sexuality can clearly assume an enormous variety of forms, and I don't have a unified theory of it. Obviously genes matter, starting with the basic facts of sex determination, and then in a more elusive way, having some effect on sexual dispositions in the mature organism. And yes, natural selection will be at work. But, in this case it is heavily mediated by culture (which is itself a realm of replicator populations), and it is constrained by the evolvability of the human genome. I continue to think that the existence of nonreproductive sexuality is simply a side effect of our genomic and evolutionary "business model", of leaky sexual dimorphism combined with Turing-complete cognition.
1bogus4yPederasty in ancient Greece was culturally very different from modern homosexual behavior though (or at least, the conventional view thereof; some people would contend that the 'ancient' model is very much lurking beneath the surface of even the most modern, 'egalitarian' gay relationships!). In that case, there was a very clear demarcation between an active participant (the pederast or erastês) who did behave 'bisexually' in some sense, but was really more properly connoted as highly masculine, and a passive participant (the erômenos) who was the only one to be specially connoted as 'feminine'. The sexual manifestations of pederasty were also criticized by quite a few philosophers and intellectuals, and the tone of these critiques suggests that pederasty could easily shade into sexually abusive behavior. (Notably, Christian morality also shared this critical attitude - the heavy censure of "homosexuality" and heterosexual "fornication" one finds in the New Testament can really only be understood in the light of Graeco-Roman sexual practices). Sex in all-male prisons also seems to share many of these same features; at the very least, if the common stereotypes of it are to be believed, it doesn't really feature the 'egalitarianism' of modern homosexual relationships!
0Douglas_Knight4yYes, the gay uncle hypothesis, that the gay phenotype has positive inclusive fitness, is absurd. But I think Elo was referring to the sexual antagonism hypothesis, that the gene increases fitness in women who carry it and decreases fitness in men. Then we are out of the realm of inclusive fitness and the tradeoff is 1:1. Moreover, if the female variant has 100% penetrance and the male variant only 1/3 penetrance, then there is a 3:1 advantage. So if gay men are down a child, female carriers only need to have 1/3 of an extra child. In one sense 1/3 of an extra child is small. It would be pretty hard to measure that sisters of gay men have 1/6 of an extra child. The claim isn't immediately inconsistent with the two observations of (1) gay equilibrium; and (2) not particularly fecund relatives. But in another sense, 1/3 of an extra child in reach is a huge fitness boost and I would expect natural selection to find another route to this opportunity. So I don't believe this, either, but it's a lot better than the gay uncle hypothesis.
0gwern4yWell, maybe. I don't much like that either since you would expect some sex-linked adaptations to neutralize it in males on the Y chromosome (and you would expect to see low genetic correlation between female homosexuality and male homosexuality if they're entirely different things) and I don't think I've seen many plausible examples of sexual antagonism in humans. (Actually, none come to mind.) It's better than overall inclusive fitness but still straining credulity for such a pervasive fitness-penalizing phenomenon. Why is that? 0.33 kids vs a mean of 2.1 and an SD of I dunno, 3 (lots of people have 0 kids, a fair number have 4-6), implies a fairly observable effect size with a sample requirement of n=1300 (power.t.test(power=0.8, d=0.33/3)), even less if you take advantage of within-family comparisons to control away some of that variance, and it doesn't require a particularly exotic survey dataset - most studies which ask in as much detail as sexual orientation will also collect basic stuff like 'number of offspring'.
0Douglas_Knight4yYour power calculation was for an effect size of 1/3, which only makes sense if you know exactly which women have the gene. The obvious test is to look at the children of sisters of gay vs straight men. But then the relationship is 1/2, so this cuts down the necessary advantage to 1/6. This has been done, but it is not at all standard, and I the sample size was too small. Aunts have the advantage of having being older and thus more likely to have completed their fertility and the disadvantage of being less related. The fertility of mothers is more commonly measured: the number of siblings. And, indeed, it is often claimed that gay men come from large families, or at least that they have older brothers. But we still don't know that the mother has the gene. As a warm-up, consider the case of penetrance still 1/3, but gays having no children, requiring female carriers to have an extra 2/3 to compensate. Then male carriers have 4/3 children and female carriers 8/3, so the gay man is 2/3 likely to have gotten the gene from his mother, 1/3 from his straight father. So his expected family size is an extra 4/9, which is measurable in a large sample. Back to my model where gay men have 1 child and female carriers 7/3. Then the gay son is 7/12 likely to have gotten the gene from his mother, 4/12 from his straight father and 1/12 from his gay father. So a naive calculation says that his family size should be boosted by 1/3*7/12 and reduced by 1*1/12, thus net increased by 1/9, which is very small. (This is naive because the fertility of a gay man conditioning on his having a child probably depends on the exact distribution of fertility. This problem also comes up conditioning on the mother having a child, but with a small fertility advantage it probably doesn't matter much comparing the mother of a gay and a straight.)
0gwern4yNot sure I follow. I wasn't talking about the gene, I was talking about the net fertility impact which must exist in the sisters to offset their gay brother's lack of fitness. If you want to see if it exists, all you have to do is compare the sisters of gay men to non-gay men; either the former have enough extra babies to make up for it or not. There is no single gene for homosexuality otherwise the pedigree studies would look much clearer than they do and not like a liability-threshold sort of thing, the linkage studies would've likely already found it, or 23andMe's GWAS would've (homosexuality is so common that a single variant would have to be very common; they probably ran a GCTA since I know they've GCTAed at least 100 traits they haven't published on but not whether they checked the correlation with chromosome length to check for polygenicity). So I'm not sure your calculations there are relevant.
0Douglas_Knight4yYes, of course all my calculations are under the simplifying assumption of a single gene. But under that assumption, sisters of gay men have only 1/2 chance of having the gene and so their expected additional number of babies is only 1/6. If you don't think that this assumption is appropriate, you can suggest some other model and do a calculation. One thing I can guarantee you is that it won't produce the number 1/3.
1gwern4yI think you're missing the point. The effect size of the gene or genes is irrelevant, as is the architecture. There can be any distribution as long as there's enough to be consistent with current genetic research on homosexuality having turned up few or no hits (linkage, 23andMe's GWAS & GCTA, etc). The important question is merely: do their sisters have enough kids to via inclusive fitness make up for their own lack of kids? If the answer is no, you're done with the sexual antagonism theory, so you only need to detect that. This is set by the fitness penalty of being homosexual, not by any multiplications. So if homosexuals have 1 fewer kid, then you need to detect 2 kids among their sisters, and so on. From that you do the power calculation.
0Douglas_Knight4yBack when you did the power calculation for 1/3 rather than 2, you didn't believe that. This number 2 is wrong for three reasons: * Inclusive fitness is irrelevant to the antagonistic selection hypothesis. (factor of 2) * It ignores penetrance, which is clearly not 100%; it doesn't matter how many children homosexuals have, but rather how many children (male) carriers of the gene(s) have. (factor of 3) * It ignores the fact that siblings only are only 1/2 related. The relevant gene(s) should only elevate the fertility of carriers, not all sisters. (factor of 2)
0dogiv4yI haven't seen any feminists addressing that particular argument (most are concerned with cultural issues rather than genetic ones) but my initial sense is something like this: a successful feminist society would have 1) education and birth control easily available to all women, and 2) a roughly equal division of the burden of child-rearing between men and women. These changes will remove most of the current incentives that seem likely to cause a lower birth rate among feminists than non-feminists. Of course, it could remain true that feminists tend to be more educated, more independent, less traditional, etc--traits that might correlate with reduced desire for children. However, I suspect we already have that issue (for both men and women) entirely separately from feminism. Some highly-educated countries try to increase fertility with tax incentives and ad campaigns (Denmark, for instance) but I'm not sure how successful it is. In the end the only good solution to such Malthusian problems may be genetic engineering.
0knb4yThere are some intelligent and interesting heterodox feminists who spend a lot of their time criticizing mainstream or radical feminist positions. I could recommend them to you, and you would probably like some of what they have to say, but then you wouldn't really be challenging your current notions and wouldn't be getting the strongest defenses of current feminist thought. I'm not a feminist (or a marxist) but I do remember being impressed by the thoughtfulness and clarity of Friedrich Engels' The Origin of the Family, Private Property and the State when I read it back in college.
0SnowSage44444yFeminist thought: "Men have power and that's sexist. Smash the patriarchy!" Anti-Feminist thought: "Feminism has too many bad eggs". Feminist thought: "You can't say that, you racist sexist bigoted bigot!"

What's up? I've read up to chapter 40 of HPMOR, and I thought I'd try talking on its forum.

0ingive4yAs an intervention, I suppose by the number of applicants. It's was mostly about changing one's essence or awareness rather than it changing itself by taking action, being responsible and not making excuses. Of course, 'clickers' can still apply but this is the new stuff, regarding non-clickers. Bachir is taking application calls publicly and it's pretty fun (Here's a Scientology mention).

1MrMind4yNope. My speculation was: It was an easy prediction.
0Thomas4ySome hint: []
0gjm4yNot a useful hint, sorry. "About half" of primes are in that sequence. The product of (1-2/p) behaves like exp of the sum of -2/p, which looks like a constant times log log N. So your product diverges to 0.
0Thomas4yYes, well ... that would be too good anyway. A finite (greater than zero) percentage of primes in N*N+1.

The point I was making is that this isn't an HPMoR forum.

What if terrorists are just a twist on the run-of-the-mill cult or suicide cult?

Could general cult-breaking tactics work on terrorists? Maybe terrorists don't have the happiest lives, find some brotherhood in a weird group, buy into it all, and thus, end up committing terrorism (inspired by sinesalvator's post on a successful plot to marry off terrorists to get them out of terrorism).

1Lumifer4ySome are. But not all. Terrorism is basically a method, a tool. People who use that method are quite diverse.
0niceguyanon4yBut how many? It seems more likely that most terrorist have shitty lives and got exposed to a dangerous and bad meme. The alternative would be that there is a certain genetic demographic that is predisposed to committing terrorism, sounds far fetched. If Christians during the crusades had modern technology 1000 years ago, we would probably have seen the kinds of solo terrorism we see today. It was really hard to be a lone fanatic trying to kill 10s of people back then with a blade.
1Lumifer4yNo, it doesn't seem like that, at all. Read something else other than hysterical mass media. Oh, and do distinguish between "professional"/successful terrorists and disposable (literally!) cannon fodder who only need to have a pulse and be insane enough to pull the cord (but sane enough to listen to instructions). I agree. That's why poisoning the well was a much better idea.

Did any of you do typing training to increase your typing speed? If so, how much time investment did you need for a significant improvement?

4MrMind4yI undertook type training at the beginning of my programming carreer, many many years ago (I used a program I think was called "Type genius"). It took me not much more than three-four weeks (although it's fair to say that I was obsessed with typing back then), and I've reaped the benefits ever since.
1ChristianKl4yHow much time did you invest per day?
1MrMind4yI think they were 45 minutes of excercises per day, if I recall correctly, but I did more.
0moridinamael4yI changed schools during the period of time when typing classes are generally taught, this led to me taking two years of typing classes. I could type pretty goddamn fast at the end of this period. That was about twenty years ago. I just tested myself at this site [] and average about 92 words per minute, which is still pretty fast. I actually feel like ~90 WPM is close to the physical limit at which point you are making most of your errors because your fingers are hitting keys out of order due to the signals being sent milliseconds apart. I doubt that I really needed two years of training to get good at typing, but on the other hand, there's something to be said for over-learning.
1Elo4yHad a high school friend typing at 145wpm casually. He was also a fast reader.

0ChristianKl4yThe German version of consumer reports recommends [] which is open source software. It seems to provide both deliberate practice and also tracking/feedback.

A lesson on the linguistic concept of argument structure, with special reference to observational verbs (see/hear/watch/etc) and also the eccentric verb "help".

I've been noticing a trend lately, perhaps others have some evidence for this.

Perhaps during casual conversation, or perhaps as a means of guiding somebody, maybe an old friend, or an inquisitive stranger, I'll mention this site or rationality as a practice in General. Typically, I get what I believe is a cached response most people saw somewhere that follows along something like this, "Rationalists are too high in the clouds to have useful ideas. Logic is impractical."

Perhaps people heard it through casual conversation themselves, but at the end of the day, there's source out there somewhere that must have blown up like any other meme on the planet. Anybody have a few sources in mind?

1ChristianKl4yBeing high-class means that you can afford to spend your time on issues that are impractical. As a result you had throughout history high class people signal the fact that they are high class by spending their time on impractical matters. Applied rationality doesn't have that much to do with using logic. It doesn't violate logic but a lot of what we talk about, is about different heuristics. It might be worthwhile to present the idea of applied rationality differently.
0dglukhov4yThis seems like an issue of conflating logic with applied rationality, then. Chances are that I made this mistake in writing my post. I'll be sure to check for conflation in the rhetoric I use, chances are that certain words used will carry with them a connotation that signals to the listener a need to reply with a cached response.
1Lumifer4yLW. Example: preoccupation with the Newcomb's problem. You think it's of any use in reality?
1Viliam4yNewcomb's problem is one possible way to explain the power of precommitments, and why "doing what seems most rational at this moment" doesn't have to be the best strategy generally. (But of course you can also explain precommitments without the Newcomb's problem.) Sometimes rationality novices are prone to use greedy [] reasoning, and dismiss everything else as "irrational". Newcomb's problem may happen be the koan that wakes them up. In its literal meaning (i.e. not merely as a metaphor for something else), as MrMind said, it's useful for people who do something with decision theory, like publish papers on it, or try to build a decision-making machine. Otherwise, it's just a curiosity.
2Lumifer4yYou can't precommit to something you have no idea will happen. In the standard Newcomb's problem the existence of Omega and his two boxes is a surprise to you. You did not train since childhood for the moment of meeting him.
0MrMind4yIt's a counter-example to the back-then prevailing theory of decision making, which is a foundational discipline in AI. So yes, it has a very important use in reality.
0Lumifer4yIn which sense do you use the word "prevailing"? I am also not quite sure how is it a counter-example. Newcomb's problem involves "choice". If you are not going to discard causality (which I'm not willing to do), the only sensible interpretation is that your choice when you are in front of the two boxes doesn't matter (or is predetermined, same thing). The choice that matters is the one you've made in the past when you picked your decision algorithm. Given this, I come to the conclusion that you should pick your decision algorithm based on some improbable side-effect unknown to you at the time you were making the choice that matters.
0MrMind4yIf by prevailing we agree to mean "accepted as true by the majority of people who worked on the subject", then it's safe to say that causal decistion theory was the prevailing theory, and CDT two-boxes, so it's sub-optimal and so Newcomb is a counter-example. That is exactly the crux of the matter: decision theory must be faced with problem of source code stability and self-alignment. Well, there's a probabilistic Newcomb problem and it's relevant in strategic decision making, so it's not very improbable. It's like the Prisoner's dilemma, once you know it you start to see it everywhere.
0Lumifer4yI don't see it as sub-optimal (I two-box in case you haven't guessed it already). I don't understand what that means. Can you ELI5? OK. Throw out the word "improbable". You are still left with You haven't made much progress.
0dglukhov4ySomething earlier? That is, who regurgitated that question to you before you regurgitated it to me? Newcomb? Robert Nozick?
3Lumifer4yI think LW was actually the place where I first encountered the Newcomb's problem. But if you're looking for origins of intellectual masturbation, they go waaaaay back X-)
0username24yI have never encountered things like Newcomb's problem before LW. And after years on this site, I still don't understand their relevance, or why the more AI x-risk people here obsess over them. Such issues have very little practical value and are extremely far removed from applied rationality. I agree with Lumifer. It's hard to look at LW and not come away with a bad aftertaste of ivory tower philosophizing in the pejorative sense.
0dglukhov4yDoesn't that bother you? If the goal of applied rationalists is to improve upon and teach applied rationality to others, wouldn't it behoove us to reframe the way we speak here and think about how our words can be interpreted in more elegant ways? It doesn't matter how good of an idea somebody has, if they can't communicate it palatably, it won't reliably pass on in time, not to other people, not to the next generation, nobody.
0Dagon4yIt would be very surprising for an agent or community to have only one goal (at this level of abstraction. If you prefer, say "to have only one term in their utility function"). There are multiple participants here, with somewhat variant interests in rationality and lifehackery. Personally, I prefer exploring the edge cases and theoretical foundations of correct decision-making BEFORE I commit to heuristics or shortcuts that clearly can't apply universally. The fact that these explorations aren't necessary or interesting to those who just want to learn some tricks to be stronger (probably, for some definitions) bothers me a bit, but more for them than for me. If you don't see how an understanding of Newcomb's problem lets you better evaluate the power and limits of a decision mechanism, that's fine, but please don't try to stop me discussing it.
0dglukhov4yI wouldn't ask anybody to stop discussing Newcomb problems, my response was solely directed at the rhetoric behind Newcomb discussion, not the merits (or lack thereof) of discussing it. I'm not as concerned about what it being discussed, as much as how. When inferential distances and cognitive biases get in the way of understanding concepts, much less make them seem palatable to read about, I'd hope people would spend more time optimizing the topic to appear more transparent. When I hear somebody claiming to have had a "bad aftertaste" from coming to this site, I can't help but think this partially a failure of the site. Then again, perhaps my standards would be too high for the discussion board...
0MrMind4yI'm reminded of a tale retold by Plato, about the famous philosopher Thales who was so intent at looking at the star that he fell into a well. This 'meme' is actually as ancient as civilization itself (Thales is indeed pre-Socratic, that is, this anecdote predates the very idea of rationality).
1gjm4yOther early tellers of tales about Thales point in quite a different direction: I think the single best-known story about him is of how one year he worked out that it was going to be a good year for olive oil, hired all the olive presses, and made an absolute killing when the autumn harvest came along. (Aristotle's telling, at least, is explicitly aimed at indicating that philosophers are perfectly capable of turning their talents to practical ends, and that if they don't it's by choice.)
