The guy who thought the value of the product must reflect the labour that went into it was Karl Marx. He was wrong.

Well, his actual claim is that any product which sells for less than its inputs cost will not exist in the long run, which is correct, because its production does not sustain itself. But this seems to be an empirically valid description of the common impression (even among Marxists) of Marx.

Well, his actual claim is that any product which sells for less than its inputs cost will not exist in the long run

As far as I remember, that's what he got to in the third volume of Das Kapital, but the first volume is very certain that the value of any product is a direct function of the amount of labour that went into it. I think the observation that Marx was a proponent of the Labour Theory of Value is uncontroversial? He didn't invent it, of course, but his name is strongly associated with it.

So, I think I've... not really 'unlocked an achievement', I guess, but hit a milestone of some sort: my first mockery in an academic publication. From the PhD thesis "Effectiveness of n-back cognitive training: quantitative and qualitative aspects", Vladimír Marček ("polar") 2014:

Now, considering this lack of clarity about IQ itself, how can the public make sense of improving IQ studies? Even more so, when research on the topic is considered a “swamp” even by experts in the field? The simple answer is it can’t. As a layman in psychology, hopefully you can tolerate the feeling of not knowing or acknowledging that we do not have enough evidence and wait and learn on the go. If you can’t tolerate the unknown you’ll probably pick your favorite study and fall prey to biased media coverage, or your friendly neighborhood intellectual, who has all the knowledge, intelligence, and especially confidence and time to argue about his opinions.
This happened repeatedly in the “Dual N-back, Brain Training & Intelligence” discussion group during my participant observation. This group, according to its owner Paul Hoskinson, has around 2500 members, from which 900 subscribed

Making the news today is MIT taking down all Walter Lewin videos (most now, some at the end of the term) as a result of their investigation into sexual harassment allegations. This seems like a gross and unprecedented overreaction (a rough equivalent of removing all Bill Cosby videos), so I would estimate that this decision will be partially or fully reversed within 1 year, with probability of 75%.

[-]Kawoomba10y140

In our ridiculous societal climate, if you're not the chief inquisitor you'll be the target of the next shitstorm yourself, #MIThateswomen. You're mostly getting punished for underreacting, so you err on the side of overreacting.

If you can't beat'em, join'em. If they are crazy, the best way to be safe is to (pretend to) lead them (unless you can avoid them, which wasn't an option).

This seems like a gross and unprecedented overreaction

Welcome to the brave new world. Blood and games, keeps us busy from dealing with the issues that matter.

6Lumifer10y

Historically speaking, not the best way. Once the ranks of external enemies thin or move out of reach, rabid movements start destroying their own.

4Kawoomba10y

You hope the roving ire of the storm front has moved on until then. (xpost /r/meteorology) There are plenty of historical examples in which monarchs sought to defuse revolutionary pressure by "joining" some of the more moderate factions, it's one of the two typical responses (placate them versus fight them). The demise of monarchy shouldn't be taken to mean that they weren't occasionally successful, see for example Victoria of England, or the German "revolution" of 1848/49. (Disclaimer: Not claiming expertise, also not a NRx-disciple.) ETA: Also, your argument seems to be "eventually the movement will turn on itself (see the French Revolution "devouring its children") once it runs out of external enemies", which is a general argument against joining such movements. However, the question is whether you're "allowed" to stay neutral and wait until the whole thing blows over. Typically, such isn't an option. Instead the alternatives often come down to "get beaten by them"/"become one of them". In which case the latter is preferable to the former.

0Lumifer10y

Typically, such is. We are not talking about acceptance or even necessary obeisance -- you said the best way is to "lead them". This means much more than just proclaiming "Yes, witches are bad, I don't like them, too". This means grabbing the torch and the pitchfork and shouting "After me, lads! I know some witches that need burning!". Take a pretty extreme case -- Stalin's Russia. You had no choice about demonstrating loyalty and singing the praises of communism and Stalin personally. But you did have a choice about joining the secret police and "leading" the hunt for the insufficiently enthusiastic.

-1Kawoomba10y

Joining the secret police would probably render you safer (note the comparative) from being their target than trying to be an accepting bystander. The 'best way to be safe', i.e. 'the safest way', not the only potentially safe way. Finding the least amount of cooperation you can "get away with" sets you up for being identified as a target. The worst case comes from underreacting, or from trying to find some middle ground which could be perceived as underreacting. Back to the MIT case, "leading" in the sense of "look, we 'sacked' the guy (in his emeritus activities) and destroyed his legacy even before anyone could even ask us for our reaction!". Leading in the literal sense: being the forerunner, not a follower, showing a preemptive radical reaction to signal "see, we're one of us, we're leading the wave of punishing the evil professor". "(Pretend to)" since clearly everyone involved there would like nothing more than the whole thing to go away, and to go back to business as usual once they've collectively passed the "we're the most progressive/feminist/buzzword institution ever, see we even cut off our own hand! (figuratively)" test. I do maintain the "typically, such isn't an option", since it referred to "stay neutral and wait until the whole things blows over". I wouldn't say "acceptance or even necessary obeisance" falls under that description, that would be along the lines of "join them". Which can mean you're safe. It's just not the safest way, which is joining the secret police equivalent. The "Gerstein Report" makes for fascinating reading, an SS scientist who purportedly sabotaged a lot of the gas production, was suspected of being a dissenter at various points, but always got away through being of high rank in the very organisation everyone was so fearful of.

9ChristianKl10y

Under Stalin party members weren't very safe. For Stalin is was more important to kill members of the party that might not be according to his standards than it was to kill random people without any political power. It was quite easy to pick the wrong side in inner party battles.

1Kawoomba10y

Good point.

-1Lumifer10y

Stalin's purges around 1937 show otherwise. That depends -- first, I'm arguing for the "hide in crowds" tactics, not for the least possible amount that doesn't get you shot immediately, and second, you are assuming the "nowhere to hide" scenario. Since we are speaking about SJWs and such, some people and organizations are forced to declare their positions, but a lot are not. But right in the parent post you talk about the necessity of "being the forerunner, not a follower, showing a preemptive radical reaction to signal". I continue to think that passive acceptance and active participation are very different things.

-1Kawoomba10y

Certainly if you can thoroughly evade the spotlight that's a good alternative and one most of us are taking right now, as we speak. Such situations do exist historically as well, no doubt, you mentioned one. I didn't mean to overly generalize in the first comment, as you say I was assuming a "nowhere to hide" scenario because in this particular case (and similar cases these days) that's what it was: the Twitter spotlight (the modern Eye of Sauron) was about to shine upon them, and they needed to frame their role thus that it reflects a positive light. Like meeting drunk soccer fans in an alley, you gotta declare yourself to be a friend of their club, if they friend/foe query you. Generally/Typically I do think that it is the easiest way (note the superlative, "the safest way") to evade prosecution when you're one of the prosecutors yourself. But of course that's hard to quantify, let alone when the domain spans across human history. I didn't mean to say that typically there are no alternatives which could also keep you safe, or that the safest way is always to join the most radical part of the winning faction. But even if you're including a margin a safety in that "least possible amount", that still puts you closer to the crazy's bad side than being one of their bannermen. If they can target e.g. Richard Dawkins / UVA / Lewin they can target anyone. Which is why, of course, ahem, I wholeheartedly support the crazies. If they asked ...

1Lumifer10y

The problem is that they commonly ask for corpses of infidels as proof of your sincerity.

-1Kawoomba10y

If it comes down to it, better their corpses than my own. Since I'm in this body, and not some other one.

-1Lumifer10y

That might be an interesting morality discussion, but would probably be high on heat and not so much on light. But let me point out that you bet heavily on the crazies winning. To return to your soccer hooligans example, your choice might be between being beaten up in an alley (if you refuse) or landing in jail for aggravated assault (if you agree and join them in persuading other teams' fans with boots and broken bottles).

-4JoshuaZ10y

Are you arguing that sexual harassment doesn't matter? It seems like your comment conflates two separate issues:1) Did MIT overreact and 2) Should sexual harassment be dealt with.

8Kawoomba10y

I don't know which comment you're responding to; I'm not sure it was mine. If it was, please explain how you could possibly get the impression that "sexual harassment doesn't matter" from my comment, or where I was "conflating" anything. If you got caught stealing, and in return your students got barred from using your library, and some of those students protested their lack of access, would a reasonable line of debate be "are you arguing that stealing doesn't matter"? Obviously not. It is not that the punishment doesn't fit the crime in that it is "merely" excessive, it is that it is incongruent in kind. Deleting learning material because of sexual online messages (I'm sorry, sexual harassment, or cyber abuse, or whichever label sounds most dramatic) is simply a non sequitur, it doesn't accomplish anything other than placate the mob, at great cost. These matters can be dealt with internally and aren't worth destroying someone's intellectual heritage over, nor punishing online learners who lose a valuable and non-harassing resource: videos of his lectures. The guy through his teaching of generations has done more for the common good than you and I ever will. To have that legacy publicly marred -- and access to his recorded lectures revoked -- because of inappropriate chat messages is simply bonkers. And yes, the above does imply that I consider grouping his probable transgressions with sexual harassment and then referring to the whole affair by that umbrella term to be a classic case of the noncentral fallacy, which rightly is called The Worst Argument In The World. No, that does not mean that, say, unsolicited online sexual messages "don't matter". Nor was such an extreme and nonsensical position contained in the grandparent comment. If he murdered his student still I would protest his lectures being taken offline. In that case, he should go to jail. There is no need to punish aspiring physics students in either case. The logical analogue of supporting MIT's

1JoshuaZ10y

You wrote "Blood and games, keeps us busy from dealing with the issues that matter." Do you want to clarify what you meant there then? Since we're in agreement that MIT overreacted, I fail to see the relevance of the vast majority of your comment.

1Kawoomba10y

Stealing is bad. We should not spend our collective attention on discussing some shmoe (nor a professor) stealing. Unrequited sexual chat messages are bad. We should not spend our collective attention on discussing some shmoe (nor a professor) sending unwanted sexual chat messages. (If you think this was sufficiently bad to warrant public attention of any kind, never ever visit Twitch.tv's chat of any female streamer. Oh Lordie (or oh Kappa, for the in-group).) The terminal problems all around us which desperately require collective attention are in such a state of being neglected (be they oeconomical, environmental, political, societal, technological or in intersections thereof) and they cannot be solved by experts without mass support (because of the vestiges of democracy) that it is comical (or, since we're in the same boat, tragicomical) to collectively talk about someone's sexual chat messages instead ("instead" because attention is a painfully finite resource). It really is. It's like seeing someone bleed out in front of your eyes and focussing on a pimple on his/her forehead. I'm not saying this particular outbreak of hysteria (and all the other nonsense we spend our hysteria on) is all some sinister plot/smokescreen from the powers-that-be to keep (part of) the bottom 99% busy. More like a happy coincidence, for them.

-2JoshuaZ10y

I'm not sure if the problem is connotation v. denotation here or possibly a motte/bailey fallacy, but I'm fairly confident that something like that is happening, or some massive failure of communication. You wrote: At minimum, the connotation of these phrases is a deliberate attempt to distract from the "serious" issues, which is an extremely different claim than the one you are apparently making above that this simply should be an extremely low priority issue. I'm also confused if you think this should be such a low priority why you persist in discussing it. I'm also highly uncovninced that this should be such a low priority issue. Sexual harrassment and associated problems contribute to fewer women in the STEM fields, which means in general fewer people going in to STEM fields than would be otherwise. All of the issues you describe as serious problems are issues where solutions, if they arise or exist, will arise out of technology and research. I'm deeply confused by this. Who are these powers-that-be and how is this in any way shape or form to their advantage? You mention the 99%, a specific idea that is in most contexts refers to a 1% income v. 99%. I'm not sure how that would be relevant to many of the serious issues that currently are issues (such as the enviromental ones you note) or others you didn't note such as existential risk. So be more explicit, who do you think benefits from this "happy coincidence" and what specific issues do you think it is distracting from that should be a higher priority?

0alienist10y

Evidence? Because, the typical argument I've seen for this claim tends to boil down to "If you even have to ask you're an evil misogynistic sexist".

0JoshuaZ10y

I'm not aware of any studies specifically. The basic argument isn't that complicated though: A) there are women who attribute their lack of involvement in the STEM fields to extremely bad experiences at an early age and B) there's an obvious way this would be causally related. Note also that some other fields such as medicine have taken more active steps to deal with sexual harrassment issues and they do have more women going into those fields.

0alienist10y

There are several problems with that theory. 1) A lot of people who deice not to go into STEM had bad experiences. (In fact bad experience may very well mean wasn't good at it). 2) The kind of things they wind up pointing to as "sexual harassment", e.g., wearing a bad 50's sci-fi shirt with 'ray-gun-babes' or happening to overhear a not-quite g-rated conversation between two men, don't seem like the kind of things people should be too bothered about. 3) Women have less variance on IQ scores then men and thus we would expect fewer of them to show up in at high levels in IQ-intensive fields. (Feminists dispute the last point, but they're arguments tend to boil down to "you're sexist for even suggesting this").

6JoshuaZ10y

I'm not sure what you mean by 1. Can you clarify? As for 2, sure there's a range of behaviors and it is worth discussing that which ones do or don't matter. At the same time, the mild behavior is the one set of behavior that we actually do have studies showing it has an impact. In particular, women who have been stared at by men then perform more poorly on math tests(PDF). Yes, up to a point. No one here is asserting that this is the only cause or the primary cause of differences in gender ratious. That's not the same thing as asserting that it isn't a cause. And IQ variance is clearly insufficient: different disciplines requiring similar needs have radically different gender ratios. And there's real evidence that in at least some cases, cultural issues are having much more of an impact than IQ- look at how the percentage of women in IT and computer related fields was steadily going up and then started dropping when personal computers appeared. See discussion here. This is now the second time you've made a comment like this- bringing up an argument that hasn't been made so you can knock it down. That might be rhetorically fun but it isn't helpful. Bad arguments are made for pretty much any position possible. The fact that such arguments are being made somewhere isn't relevant for fairly obvious reasons.

6gwern10y

That's a paywall, so I assume you have not read it. Here's a jailbroken copy: "When What You See Is What You Get: The Consequences of the Objectifying Gaze for Women and Men ", Gervais et al 2011 (Libgen; PDF.yt; Dropbox). This paper inherits the usual defects of the 'stereotype threat' literature. It takes place in no-stakes situations, while stereotype threats have failed to generalize to any situations that actually matter, and blinding is questionable (they bring the subjects in, then "They also learned that they may be asked to report their feelings about themselves and others and to complete word problems", and do math problems? Gee, I'm sure none of these undergrads recruited from psychology classes figured out what the real experiment was!) The results are also a little bizarre on their face: "...the objectifying gaze also increased women’s, but not men’s, motivation to engage in subsequent interactions with their partner...the objectifying gaze did not influence body surveillance, body shame, or body dissatisfaction for women or men". Huh? And finally, this is social psychology. That does not follow. If different disciplines have non-identical needs, then depending on the exact differences in distribution shape, the correlation between IQ, and the cutoff for success (see for example the table of r vs cutoff in "What does it mean to have a low R-squared ? A warning about misleading interpretation") - not to mention the other variables which also vary between gender (Conscientiousness; degree of winner-take-all dynamics; expected work hours) - may well be sufficient to explain it. You'll need to do more work than that. See discussion here.

-1JoshuaZ10y

Sure. It is extremely difficult to test these situations in high-stakes situations for obvious reasons. This is an intrinsic problem in almost all psychology studies. Is there anything specific here that's worse than in other cases? I don't see what your point is. What do you find is bizaare about this and how do you think that undermines the study? That's a reason to be skeptical of the results, not a reason to a priori throw them out. You are correct. The word clearly is doing too much work in my comment. At minimum though, the fact that other similar disciplines don't have that situation even though they historically did is evidence that IQ variance is not all that is going on here. And that's especially the case when many of those disciplines are ones like medicine that have taken many active steps to try to encourage women to be interested in them. Now seen. Having read that discussion, I agree with Kaj there. Do you have any additional point beyond which you said to Kaj there?

4gwern10y

It is not so difficult as all that: high-stakes tests are conducted all the time and gender is routinely recorded. I refer you to the WP article for how stereotype threat evaporates the moment it would ever matter. It is not that bad a problem in most studies, and stereotype threat studies are particularly bad. Their results make no sense in almost any causal model of how stereotype threat would work. What sort of stereotype threat has no effect on attitudes and body images and increases interest in co-workers, and how would you expect this to support the argument you made with regard to co-workers in the real world? Indeed. So why did you cling to a weak reed? No. I stand by the sum of my comments: that it is blatant post hoc rationalizations which contradict any theory a feminist would have made before seeing the actual data, which clearly supports an economic rather than pure bias account, and makes false claims about new CS students as well.

2JoshuaZ10y

Which studies there are you referring to as being relevant? Note by the way that the study in question isn't quite the same as stereotype threat in the classical sense anyways. I'm not completely sure what model would actually do this but it could be something that causes them to think of themselves less as people doing math and more as people who are socially or sexually interested in others. But the fact that it didn't have an impact on body image is strange, and needs further investigation. In the short version though, that should suggest that this study actually is more reliable: one of the most common criticism of psychology as a discipline is that the studies have way too high a confirmation of hypotheses rate. That's been discussed on Less Wrong before. In this case, the fact that part of the study went against the intuitve hypothesis and went against what the authors explicitly hypothesized is a reason to pay more attention to it. Because this is one of the very few studies that have looked at how sexualization impacts performance. There are a lot of stereotype threat studies (as you noted) but they don't generally look at this. I'd be happy to rely on something else or change my opinion here if there were that many more studies. So in your view, what precisely is the reason for the fact that the percentage of female CS students was consistently rising and then took a sharp drop-off? Also, why do you think Kaj disagreed with your position?

2gwern10y

If you aren't going to read the links I provided*, I'm not going to bother continuing. Both of those questions were answered. * please note I have already gone above and beyond in not just reading your source material while you have not, but jailbreaking & critiquing that study, and also excerpting & linking contrary opinions & surveys

0JoshuaZ10y

I read the conversation with Kaj and I read the links thank you very much. In that conversation you brought up a variety of different issues, focusing on the "practicality" issue but you give multiple different versions of that claim and I'm not completely sure what your primary hypothesis is. The primary claim there seems to be that the ups and downs on the graph mirror ups and downs in the market, but the primary link justifying that claim is this one you gave which doesn't make any claim other than the simple claim that the graphs match without even showing that they do. The only bit there is there that is genuinely interesting evidence is the survey showing that women pay more attention to job prospects when considering fields which is not at all sufficient to explain the size of the drop there, nor the fact that law didn't show a similar drop in the last few years when there's been a glut of lawyers. I don't know where you are getting the second part of that claim from. But it is true I didn't read every single link in the Kaj conversation, and I'm not sure why you think reading a single study is on the same scale as reading an additional long conversation and every single link there. So if you want to point to which of those links matter there, I'd be happy to look at them.

6alienist10y

On the other hand, the fact that such arguments are used to intimidate anyone who dares question a certain position is relevant (possibly successfully remember what happened to Summers). In particular it affects what arguments we expect to have been exposed to. Furthermore in Lewin's case we have no idea what he actually did, thus the only evidence we have is that a committee at MIT decided what he did was bad. Thus to evaluation how much we should trust their conclusion it is necessary to look at the typical level of argument.

0JoshuaZ10y

It isn't at all relevant. To use a different example (coming from the other side of the poltiical spectrum)- one argument made against releasing the recent torture report was that anyone wanting it released was "anti-American" which is essentially the same sort of thing. The presence of such arguments is in no way relevant to any actual attempt to have a discussion about whether releasing the report was the right thing. No matter what position you discuss someone will be using bad arguments to intimidate people into silence. Rise above it. The typical level of argument isn't that when it comes to sexual harassment though. The typical level is a massive mix with some universities overreacting, and other's underreacting. For every example of a university overreacting there's an example of it underreacting. For example here. But this also isn't relevant for another reason: this entire subthread isnt even discussing the specifics of the Lewin case but a more general question of whehether such issues matter and are worth discussing. It is a red herring to go back to the original situation. But if you really do care about that situation, it might be worth looking at what Scott Aaronson has said on it, I'm curious if this adjusts your estimate at all that this is a minor situation being overblown?

3alienist10y

I've been somewhat following the situation, and yes it is. The fact that you would claim otherwise cause me to update away from trusting other claims or judgements you make on the subject. I didn't see anything in the article that would adjust my estimate. The only thing there is that some who know told Aaronson that "this isn't a borderline case", given the kinds of things feminists consider "not borderline cases" these days that isn't strong evidence.

2JoshuaZ10y

I'm not sure a polite response to that, so let me just ask, given that I just pointed to an example that went in the other direction, maybe it is worth considering, just maybe, possibly, that you are vulnerable here to a combination of confirmation bias and what media sources you are using? Let's as a start focus on a simple example: were you aware of the example I linked to above before I linked to it? At this point, I think we may be having problems with radically different priors, part of which is that I give Aaronson enough credit that I don't think he's going to go the most radical end of the women's studies department and ask for their analysis to get some idea of what happened.

1bogus10y

Aaronson's post also states that the incidents occurred online, and for that matter on the MITx platform, which caters to MOOC users, not actual MIT students. Given these factors, I just can't see how MIT's Damnatio memoriae towards Walter Lewin could be anything but an outrageous overreaction.

-2JoshuaZ10y

I'm not sure at all the relevance of your comment in the context of what we are quoting. The fact that this was not the regular MIT students has been known for a while. I'm also not sure what that has to do with my comment, since everyone here is in agreement that the removal of the videos was an overreaction. (However, I'm not at all sure how the fact that it was with MOOC users rather than regular students makes any difference whatsoever unless you are talking about a very marginal difference in legal liability.) What is the connection between your comment and the part of my comment that you are quoting?

-1alienist10y

He can only get information from the people who handled the case, who are likely to be SJW-types.

0JoshuaZ10y

These issues are handled in general by university committees. Does your lack of knowledge on this fact cause you to update at all about how good your judgment is for such issues? Also it is worth noting that "SJW-types" in most contexts is a group which is by and large restricted to certain parts of the internet or some parts of certaind departments on campuses.

-1Kawoomba10y

Yes, we evidently disagree on that. Let's identify that as "area of contention #1", before we dive into the specifics. I do disagree with your chain of reasoning of "(sexual harrassment) leads to (fewer women in STEM fields) leads to (fewer/worse technological solutions to the 'all the issues I described')" playing a role commensurate with the hubbub we spend on the topic. There are many aspects to each of the causal links (for example: is the sexual harassment situation in STEM fields particularly bad, as opposed to other university courses, or as opposed to non-university occupational choices?), and I doubt a few paragraphs will suffice to cause either of us to update. I don't mind delving into #1 by any means, but let's divide and conquer, since #1 could keep a serious discussion going for months. If you saw the public discourse and the attention of the public raptly focussed on the welfare of ponies, to the exclusion or at least neglect of all other pressing problems, you'd discuss such a misallocation of resources as well, even if you didn't care about ponies one bit. "This is not what we should spend our attention on" would probably be your message, or what other reaction to a hypothetical pony craziness would you implement? This is just an edge case to illustrate the principle; concerning sexual harassment, which is a serious issue overall (though less so when we're talking about chat messages), the message would be "This isn't what we should spend such a huge amount of our attention on" (versus "no attention at all on"). Everyone who profits from the status quo. Which is disproportionally the global elites, those who neither suffer from droughts, nor from a lack of healthcare, nor from transmittable diseases (comparatively), nor from job insecurity, nor from ... you get the picture. Those who bought and paid for government initiatives (or the lack thereof) via myriad lobby groups. This isn't some conspiracy theory; there are many different groups with m

0JoshuaZ10y

Sure. I'm curious, by the way, if you saw my reply to Alienist which discussed some of the basic evidence for this being an issue. Sure, but it doesn't need to be substantially worse as a whole to have a disparate impact. Sexual harassment can combine with other problems (e.g. a pre-existing gender imbalance as well as larger cultural issues). Ignore it completely, just as you and I are ignoring what the vast majority of people really do seem to care about- e.g. celebrities. In general, if there really is a problem and some humans are putting resources into handling that problem, it isn't likely to be productive to spend time telling them that they should go do something else. It also isn't helpful to then use language that essentially compares caring about a cause to being somehow complcit in Roman style bread-and-circuses keeping the people down. How does being well-off and not suffering from any of those problems mean that one somehow benefits from the status quo? If global warming becomes a serious enough problem, it is inconvenient to everyone. If a paperclip maximizer turns all into paperclips everyone has the same problems. And at the same time, if more people are in the STEM fields or more people who can succeed at it, we all benefit.

3alienist10y

The problem with that is that the over-focus isn't harmless, it's already having negative effects, e.g., Lewin's videos being taken down. Also this is not the kind of thing that's smart to ignore for them same reason that someone living in Salem Village in 1692 probably should not ignore the increasingly popular silly belief that a lot of their problems are caused by witches.

0JoshuaZ10y

Sure. For any given problem, some degree of focus, whether it is an overfocus or not is going to have some negative side-effects. That's essentially just the non-onesided nature of policy issues. So the question becomes where do you balance it? And moreover, how do you decide that it really has gone over too far in one direction or aother? Can you expand on this logic?

Eh, I'm not gonna call "women being stared at" and such sexual harassment, which is what we are talking about. As I've mentioned, to discuss sexual harassment in general when our starkest disagreement lies in the sexual chat messages and the like is a Worst Argument In The World situation in any case. If you have a phenomenon with multiple causes I wouldn't characterize a minor causal node as having a "disparate impact" just because it contributes to a much larger phenomenon. The only thing necessary for the triumph of evil is for good men to do nothing. If you saw MIRI going off on a dead-end tangent, and you are invested in its fate, "ignore it completely" is a bad choice. Same dynamic. If the resources were allocated appropriate to the problems, where would the money come from? For carbon licenses and other Pigovian taxes? Yea, from the powers-that-be. Solving it inconveniences ExxonMobil more, for the next few hundred quarterly reports. Certainly. The first step for that should be creating better role models, getting rid of the ridiculous "I'm a fragile flower waiting for good things to happen to me, since I deserve everything"-entitlement attitude people are developing, and creating more of a meritocracy (e.g. not turning people away because they have the wrong gender / wrong nationality etc.). Not becoming hysteric over sexual chat messages, when there are already rules in place against that sort of thing (and yes, the professor should be reprimanded and, if repeated, suspended, but goddamn that should not be national news).

The point here should be clear: of course it isn't sexual harassment. Yet the data shows that even that limited form of negative interaction can have a substantial impact on performance. A fortiori you'd expect the same thing for more serious situations. Huh? First of all, it is highly likely that what happened with Lewin went well beyond any sort of mildly sexual chat messages. Second, the primary argument isn't even about that but the claim that in general, sexual harassment shouldn't be a high priority. Missing the point. It may not be a minor causal node. The ability to identify one cause among many isn't a reason to think that it is a minor node. I can identify hundreds of ways humans die: it doesn't make cancer a minor node just because it is one among them. Moreover, in this sort of context different nodes can interact to have an impact substantially larger than any single one would. Sure, but that's a specific organization with a specific set of goals. If you think this sort of thing is important then why don't you go around telling everyone who talks about celebrities or Hollywood movies or whatnot how they are wasting their time? Is wasting time your true objection? Ok. So it is a problem for almost everyone, and anyone at ExxonMobile who cares about their children. There's still no large set of "Powers that be" that all these problems apply to. Yes, there are small, specific groups that have interests which are counter to the interests of the general population for specific issues. But none of those will see eye-to-eye on the same issues. This seems more like a series of boo lights and labels for people you don't like then a substantial point. I am however curious if you've been subject to unwanted sexual attention from people in a position of power. Have you? How frequently? How did you react? How did it make you feel? And what makes you so confident that in the actual situation in question that this was so mild that anyone who reatced can be labele

Beware the man of one study who uses that study for conclusions concerning different phenomena. That's not how evidence works, the correct Bayesian update "a fortiori" on different behavior would be negligible. How does that even work, "if they are sexually messaged they do worse on math tests"? Hello there "mildly", I didn't see you in my original quote. That must be because you came out of thin-air. It can be explicit enough to fit right into some Gangsta rap song, it's still a chat message which shouldn't be discussed in the same breath as e.g. violent sexual assaults. I reject logic along the lines of "A belongs to B, C belongs to B. We should deal with A because C is really serious, and we'll transfer that association with seriousness to A via B". If you want to talk about men staring at women, and what policies and punishments we should have for that, we can do that. Or for when an authority figure writes sexual messages to a college student. These are neither in kind nor in degree the same thing as many other forms of assault, sexual or otherwise. You probably agree, so let's not strawman "sexual harassment shouldn't be a high priority" out of "sexual chat messages shouldn't be a high priority". Don't slippery-slope your way from "men staring at women" to sexual harassment as a whole (including e.g. violent rape), these are different problems requiring different solutions and most importantly different amounts of societal attention and anxiety. What you said was "Sure, but it doesn't need to be substantially worse as a whole to have a disparate impact. Sexual harassment can combine with other problems (e.g. a pre-existing gender imbalance as well as larger cultural issues)" which I understood as "even if the difference was minor, combined with other factors the overall impact can be large". If you only intended to say "if it is a significant causal link on its own, it is a significant causal link on its own", that would merely be a tautology and a reminde

-2JoshuaZ10y

That's relevant when you have other studies that show something in the other direction and one is picking one study exactly. Do you have any similar studies to mention? Since you've mentioned exactly zero studies about behavior or any links to any stats in this conversation, my guess no. Really? This seems pretty clear. If weak examples of A cause some amount of X, then one should expect that more extreme amounts of A cause more of X, and in this case we have an easy causal model that supports that. You're right. Poor rephrasing on my part. But no one here is claiming they are the same as "violent sexual assaults". Did you see anywhere I or anyone else in this subthread tried to make that claim? That's not what I said. Please reread what I said without trying to make it the stupidest argument you can. I'm confused. Do you see the celebrities and movies as in the same category or not? And if you don't why don't you spend time telling people to stop focusing on them? In general, politically involved topics lead to toxic climate. There's nothing special about the topic in question. And in your view they coordinate that how? Google and Exxon have wildly different goals as do the MPAA and Google and any other two major powers you can name. No. A thousands times no. As should pretty obvious since I made zero comment about your gender. But here's the thing: it is really easy to label people as "fragile flowers" or the like when they've had bad experiences you have not. What this reminds me of is an old English teacher I knew in highschool who used to complain that it was no longer acceptable for students who had a disagreement to just leave the class-room and settle things "out doors"- he thought that this was making a weak generation of students. I believe he actually used the word "sissies" and said that the solution was for nerdy students to "man-up". But we've decided that that's not acceptable, and I suspect that you agree there. And we've all benefited. Let

Since at this point we probably regard each other as fully mindkilled on the subject (at least I can vouch for one half of that statement), we should probably stop. I shall leave you the last word. My reply would be along the lines of Pedophile hysteria is part of the problem in the same vein as rape hysteria and sexual harassment hysteria in general. Ok then: why would you even question my personal experiences if not to discount my opinion on that basis, since if you're not facetious you know I'm male and probably haven't received unwanted sexual chat messages from female professors. It's an obvious set-up to an ad hom. Otherwise explain the question. Entitlement culture and a loss of the ability to concentrate and exhibit mental discipline have become endemic (take obesity as one marker), my 'fragile flower' comment was meant to apply stochastically across the board, not to the student in question specifically obviously. You must think me to be some crazy misanthrope or somesuch. It seems like the familiar "enemy detected"-pattern of political discourse. It seems like we're regressing ... didn't we already cover that? But since you ask ... again ... let me quote ... a comment like 5 ancestors up: It's easy to paint people who disagree as conspiracy nuts. Don't fall into that temptation. I did. I have no idea what you were trying to say there, if it apparently was neither "if it is a significant causal link on its own, it is a significant causal link on its own" nor "even if the difference was minor, combined with other factors the overall impact can be large". Both are apparently the stupidest argument I can make up? Which is why I asked if I understood you correctly? This is where I expected some sort of troll face following the quote. We seem to live in different slices of society, I can't explain why our perception would differ so fundamentally otherwise. Except the very first line of this comment, that is. Even Robin Hanson, of all people, became a tar

2JoshuaZ10y

That's a fascinatingly passive-aggressive way of saying "I think you're hopelessly mindkilled". To be blunt, while I do certainly have suspicions in that direction, the outside view suggests that neither of us is mind-killed as much as we think the other person to be since both of us have taken positions with some degree of nuance. Not really. They aren't raised by the same people and they don't even always occur in the same places. For example, much of the UK has massive pedophile hysteria but in many ways much less of a focus on sexual harassment issues than the US does. I did explain it. Please reread what I wrote right after that sentence where I said " it is really easy to label people as "fragile flowers" or the like when they've had bad experiences you have not." The point is that it may be worth considering whether the labels and descriptions you are attaching are based on you not having been on the receicing end. And didn't you just reference the idea that politics is the mind-killer? Sure, different political subjects will lead to different degrees of toxicity in different contexts but this is very much not the only one which can do so. Try to have a conversation with a random bunch of Americans about abortion or gun control. I don't see why you see that as such an extreme thing. Robin is a borderline professional troll who trolled his way to tenure. He first became welll known for his fairly tone-deaf pushing for terrorism futures markets(pdf). I'm familiar with it, and you need to reread what I wrote since that's not what is going on here and the fact that you brought up rape (which is genuinely distinct) if anything shows how that's not what is going on. The point here is that actitivies which in an academic context can sexualize women make them perform more poorly. That's the common connection between the staring and sexual harassment situations. It has nothing to do with rape at all - I agree that if one were trying to make such a connection that

As it happens half the issues you raise there are also distractions, but best. A number of them are also ways for the elite to con the populace into giving them more power. Keep in mind that just because you've seen through one smoke screen doesn't mean there aren't others. To take the example of Citizens United, the question there is whether a group of average individual citizens can pool their resources to create lobbying groups that have a chance to compete with individual wealthy and/or well-connected citizens.

2alienist10y

Another question is whether Lewin is actually guilty of sexual harassment. This raises the question of how exactly "sexual harassment" is defined. Given the kind of things feminists have been trying to get away with (and scarily enough frequently succeeding) with calling "sexual harassment", for example see the recent #ShirtStorm incident (or elevatorgate, or DongleGate), my prior is that whatever Lewin did doesn't mater. That is if you call whatever Lewin did "sexual harassment" then "sexual harassment" doesn't matter, and if you define "sexual harassment" to only include things that matter then Lewin isn't guilty. Now you might ask how exactly I can be this confident without knowing what exactly Lewin is supposed to have done. Well, Im basing my prior on a combination of two things: 1) We are in the middle of a witch hunt against "rapists" and "sexual harassers", especially on campus, with respectable columnists arguing that we shouldn't let mere facts get in the way of fighting "rape culture". 2) The reason I don't know what Lewin is supposed to have don't is because MIT hasn't seen fit to inform the public of any details. To see how big a red flag this should be, imagine if the authorities had accused Lewin of terrorism, but without even describing the plot he was supposedly involved in, much less any actual details. Would you take the official account at face value?

Richard Feynman may have been a creep-and-a-half, but it would be a shame to stop publishing the Feynman Lectures on Physics on that regard. (That said, Richard Feynman is dead and therefore cannot sexually harass any of his current readers.)

7Vulture10y

A similar argument could be made that a pre-recorded lecture cannot sexually harass someone either (barring of course very creative uses of the video lecture format which we probably would have heard about by now :P ).

7fubarobfusco10y

From the MIT press release, it sounds as if the former professor emeritus¹ has been harassing online students through means other than pre-recorded videos. ¹ Would that be a professor demeritus?

It's MIT - they have lots of compelling lecturers. Far more likely one of them will be tasked with producing a replacement series long before then. Actually, that's probably already in motion.

4Douglas_Knight10y

Lewin spent 25 years recording lectures. That's a quarter century working on them after he was singled out as the guy to do it, some combination of already being a good lecturer and willing to put in the work. And, no, MIT does not have a lot of compelling lecturers -- the teaching prize is known as the "Kiss of Death Award."

The key question is whether this action increases or reduces the amount of people that watch the lectures. Has anybody any guesses?

As far as I understand some form of consequentialism is the default ethical system on LW. If the action has positive consequences, why should it be unethical?

4Shmi10y

I don't think (even) in consequentialism you include unforeseeable consequences into the ethical assessment of an agent. If someone plans to kill their neighbor but instead their polonium-laden coffee turned the neighbor into spider-man, they are still just as immoral, even if the act itself can be retroactively deemed good. You might even hail the agent for helping save the human race from the evil Doctor Octopus, but you certainly would not want to be their neighbor, no matter how consequentialist you are.

2ChristianKl10y

The streisand effect is not a unforeseeable consequence.

2Shmi10y

True, but then if it was foreseen and used intentionally to bolster Lewin's viewership, then the ethics of the administration is even more questionable. Also, it feels like you are now arguing for the sake of arguing.

0ChristianKl10y

I don't think it makes sense to do things for a single reason. It's better to look at the likely effects of a decision and then decide whether or not you want to go the road that leads there. It's still punishment for Lewin to stop hosting his videos. It's likely perceived by Lewin that way. It's perceived by the media as a symbol for it. All the social justice people feel good because of the symbolic act. It still puts the video outside of MIT.

0Lumifer10y

The professor probably has hidden all sort of sexual suggestions in his lectures that MIT doesn't want to be associated with. Scott Aarasson writes that "Prof. Lewin tells the students that they’re about to lose their “Maxwell’s equations virginity.”" The old professor toyed the line of what can be said in todays world of politcal correctness. That pitch might just work to get people interested.

Last week I was going to ask if anyone had recommendations for nerd-friendly resources on public relations. Then I remembered where I was, and went "ha ha ha!"

This was possibly unfair.

Out of the many people who read Less Wrong, it feels like one or two of them should be able to recommend a good entry point for any given subject. We've got physics, mathematics, statistics, computer science, et al covered, but other areas don't enjoy the same coverage.

It does seem to me that if there were someone on Less Wrong with a background in PR (or constitutional law, or the Yugoslav conflict, or whatever), they'd probably have some ideas about what material other Less Wrongers might find accessible or valuable. With that in mind, does anyone want to volunteer an unusual-for-LW academic or professional background we can mine for information?

9satt10y

To fill that last gap while we wait for an actual expert to arrive, I offer my own reading list on the Yugoslav wars of the 1990s. Actually, it is also a watching list, because I recommend doing as I did by starting with * The Death of Yugoslavia (1995), 6-part documentary produced by Norma Percy & Brian Lapping with the BBC (and the Discovery Channel and VPRO, among others) Watching TV science documentaries mostly soured me on documentaries in general, because I realized they have a woeful information density compared to academic books. But as an introduction to a tranche of history, a lower density documentary* was extremely useful for learning the names & places I needed to know to understand chapter- and book-length treatments of the wars. If I read someone's name in a book I'm likely to forget it before it crops up again, but if I see ten clips of someone answering questions with their name hovering by their head, I have a good chance of remembering who they are. (Something I like a lot about the documentary is that it's not stingy with the name captions.) It also helps that the series mixes things up with photographs, maps, tourist adverts, state TV cartoons, contemporary news reports (and yes, old Yugoslav TV looks about as you'd expect it to), at least one snippet of hidden camera footage, recordings of phone calls, and amateur camcorder film. A downside of Death of Yugoslavia is that it's too old to cover the war in Kosovo, but it's still indirectly helpful there because it gives a fair amount of background information about the province. I've also seen allegations that the film's English translations are tendentiously inaccurate, but the only remotely reliable source I have for those claims is a couple of references to ICTY transcripts in the documentary's Wikipedia article. Once you know the broad structure of the wars, it's time for books. The documentary has an accompanying book, also called The Death of Yugoslavia, and I've yet to find an academi

An update for future readers on the Death of Yugoslavia documentary and the accuracy of its subtitles: idupizdu (heh) on YouTube is the first person I've seen to step up and list specific subtitles they think are tendentiously mis-translated. They give 17 examples, each comparing idupizdu's transcription of the spoken Serbo-Croat, idupizdu's own English translation, and the documentary's subtitled translation. Most of the examples strike me as fairly innocuous, and I reckon the subtitles' imprecision in general is explained by the usual preference of TV editors for concision over accuracy. Still, I'm grateful to idupizdu for cataloguing examples so others can decide for themselves.

PR is a quite wide field. I personally have been multiple times on TV, radio and mainstream newspapers for the topic of Quantified Self. One of the best books to read on PR is likely Trust Me I'm Lying by Ryan Holiday. Ryan Holiday is a nerd and was Director of Marketing for the clothing company American Apparel. He also did PR for a few authors such as Robert Greene and Tucker Max. Even when you don't want to use some of the dark arts technqiues he writes about, reading his description of how US newsmedia works, is likely very useful.

At the Less Wrong meetup yesterday we played the Less Wrong Name Game. You may know the regular Name Game by another name. It involves all players having the name of a celebrity, historical figure, fictional character, etc., attached to their forehead. The identity of each figure is not known to the player labelled with it, and they must deduce this identity by asking a series of yes/no questions. In the Less Wrong variant, we gave each other identities from the Less Wrong memeplex/ideosphere.

We played this fairly late on at the meetup when we were down to six attendees. Our identities were Peter Singer, Aubrey de Grey, Yvain, Moloch, Philip Tetlock and The Sorting Hat.

This was fun, informative and pleasantly in-groupish. That said, when labelling someone else, I'd suggest being very sure that they've heard of the person you're assigning to them. We now know quite a few obscure facts about Philip Tetlock.

First quote about Lesswrong:

4Vulture10y

I have to say I appreciated the first description of LessWrong as "confoundingly scholastic".

1dxu10y

That seems somewhat uncharitable. Most critiques of Less Wrong I've read seem to be predominantly predicated on the fact that it seems "weird". This is unfortunate, in my opinion, as Less Wrong actually has a lot to offer, and it's a shame that people are turned off by their first glance. Articles like this only serve to heighten the effect, especially since readers might not even visit Less Wrong after reading such an article. I have to confess that I wish journalists wouldn't do this sort of thing... ...but that's little more than a pipe dream. Non-academic journalism has notoriously low standards, which means they can pretty much write whatever they want. Which means that if we want to stop getting called out as "weird", we're the ones who're going to need to do something about it...

1ChristianKl10y

The article basically says that we are a bunch of weird people with an average IQ of 138. That means that most people who read the article won't think they are at home on LW and most people probably wouldn't. On the other hand readers who want to take part in a high level discussion forum, might be motivated to check out LW. It's okay that not everybody wants to join LW.

Further thoughts on Imaginary Expertise...

I'm currently studying a final-year undergrad course in the mathematical underpinnings of statistics. This course has three prerequisite courses, all of which have the word "statistics" or "statistical" in the title. While the term has obviously come up beforehand, it was only a couple of chapters ago that we were given a formal definition for what a "statistic" is, (in the context of parameter sufficiency).

It occurred to me that if someone was ignorantly mouthing off about statistics, and you wanted to shut them up, you could do a lot worse than to ask "so, what exactly is a statistic?"

I've noticed beforehand that "so what exactly is money?" has a similar effect for economics pseudo-blowhards, and "so what exactly are numbers?" for maths. It's worth noting that these questions aren't even the central questions of those disciplines, (insofar as such broad categories have central questions), and they don't necessarily have canonical answers, but completely blanking on them seems indicative of immature understanding.

I've now taken to coming up with variants of these for different disciplines I think I know about.

[-]Vaniver10y110

completely blanking on them seems indicative of immature understanding.

Or of question ambiguity. If the word exists on many layers, and they're not sure which one you're asking about, they might get stuck there. I notice that I mostly agree with your questions (a 'statistic' and 'money' are both fairly crisp ideas that have a clear use in their respective fields, and so even just pointing at what they're used for is a decent definition), but that bramflake's suggestions all seem problematic.

5DanielLC10y

"Money" is a vague idea. It's defined as something that can be traded for goods and services, but everything can be. It's just a question of how quickly, reliably, and consistently it can be done. Out of necessity, economists have given precise definitions of "money". At least six of them.

2Vaniver10y

Sort of? The sentence that immediately follows seems precise enough to me, and is the same idea (though different words) than the definition I had in mind. If someone jumps to, say, "root of all evil" or "shared fiction" instead of "trade," that does seem informative about their blowhard-nature.

8Punoxysm10y

This is somewhat unfair. If you already think someone's a blowhard, and you want to take the wind out of their sails, go for it, but a lot of people who have some legitimate expertise won't have a definition at their fingertips. Or if they do know, you'll tip them off that you don't think much of them. Or they might give a legitimate answer that differs from your own flawed understanding. In which case you're just a jerk to judge them by it.

1sixes_and_sevens10y

Reiterating what I said to ChristianKI, it's not about seeing whether the person has a "correct answer", but whether they're already aware it's a non-trivial question.

3Punoxysm10y

I'd still say it's unfair. I was burned by a question like this in a job interview. Would you agree that that sort of high-pressure context is a poor place to ask questions like this?

2sixes_and_sevens10y

I'm not sure how the conversation got here. Your question is reminiscent of a friend or partner talking about the perceived-wrongdoing they suffered at the hands of a mutual acquaintance, before asking "don't you agree it was wrong of them to do that?" It's not obvious to me that interviews are a bad situation for questions like the ones I describe in the OP. I don't know the circumstances of the interview you experienced, though I can believe it was conducted poorly and you have my sympathies. There are obviously social consequences to going round putting people on the spot with awkward questions all the time. If people can't exercise good judgement in this matter, I don't think anything I write will save them from themselves.

2Punoxysm10y

I'll clarify: I think the ability of people to respond adequately to these questions depends as much on their confidence as their knowledge, and that interpreting their answers is very subjective. In general, asking your suggested questions are a good way to make someone look dumb or fluster them, but not the best way to correctly identify their expertise. Only in limited contexts are questions like these asked in good faith. They're still valuable to think about because if you're ever in a position to receive these sorts of questions, you should be prepared to give at least a couple types of concise and competent-sounding answers, whether the question is asked in good faith or not.

3gothgirl42066610y

This seems incredibly obnoxious and I don't understand how it's helpful. It reminds me of a little kid playing the "Why?" game. Regardless of whether someone can provide a precise exact definition for "money", I think we all understand what it is on some level. You don't have to define every single word you use in a conversation, because the definitions are already assumed to be understood... that's the whole point of having words. I agree that there are situations where two people might fundamentally disagree on the definition of a word they are using and unless they define it they will never get anywhere (e.g. utilitarians and deontologists arguing over what is "good"), but I don't see how these situations are like that. I'm not an economist or statistician but: Money: an item with no inherent worth of its own, but is understood to have a specific value and can be traded for goods and services Statistics: facts about the world that are expressed in quantitative form I don't know how either of those advanced my understanding. Also I have had the opposite problem with academia, I find it really annoying how every professor feels like they have to spend the first day of class on "what is design?" or "what is psychology?" or "what is logic?" or etc. etc.

0sixes_and_sevens10y

Well, what is logic? Would some hypothetical alien civilisation have a notion of propositional logic, complete with equivalents of syllogisms and modus tollens and all that stuff? Would any of it be different to ours? Would they even have a concept of "proposition" or is the whole endeavour a weird parochial human construct for navigating the world? It kind of feels that logic and mathematics exist independently of logicians and mathematicians, somehow. But how? Is this actually the case? What is logic "made of"? Is this question even meaningful, and what does that say about how the universe works? This is interesting. It's certainly way more interesting than never asking what logic is. Most people never do, and yet they still use the word "logical" in an intuitive, folksy way, convinced that they know exactly what it means. The word that comes out of the everyday user's mouth is loosely pointing to the same set of ideas that philosophers talk about when they talk about logic, but the everyday user has never bothered to follow the pointer to see where it goes. The point of asking questions like this is to find out what ideas we take for granted without being aware of the complexity behind them. As a material object, contemporary fiat money isn't unusual, but as an artefact of human culture it has some of the weirdest properties you might possibly hope to dream up. In order to appreciate this, you have to think about what money is. Plenty of people are happy to talk about quantitative easing, the gold standard or the Eurozone as if they know what's going on, and yet they haven't asked themselves this question. Maybe they should ask themselves this question, is all I'm saying; and if they're not in a position to ask that question to themselves, maybe someone else should ask them.

0Lumifer10y

They probably didn't because your definitions are wrong. Until relatively recently, money did have intrinsic value. A trivial example: gold coins. And a statistic is a technical term in statistics which has nothing to do with what you said.

I don't really like these questions. "What exactly is a number?" doesn't really have an answer. I can give the standard answer about representing integers as certain sets. And I give the details of constructing the real numbers either as cuts or Cauchy sequences of rationals. But neither answer is very satisfying imo. Saying that integers "are" certain kinds of sets seems wrong to me (as it does to Tim Gowers). My feeling is I don't know what numbers exactly are. I understand you probably are going to attack someone's expertise if they blank and can't say anything. But people react to things differently. I could imagine a version of myself who was didn't realize she needed to spout information even if she couldn't answer the question fully. The other problem is my best friend studied computer science not mathematics. She is however much more intelligent than myself. Her knowledge of math is really quite good. She can give the "standard answer" to "what is an integer" but cannot give the details of a construction of the real numbers (I just asked her). So I really think we should be careful about these gotcha questions.

0sixes_and_sevens10y

I might edit the OP. It's not about there being a right or wrong answer. The whole point of asking the question is to discriminate between "'what exactly is a number?' is a deep, nebulous, philosophical question we don't have a satisfactory answer for" and "'what exactly is a number?' is a trivial question I simply haven't asked myself yet". It's also not necessarily about posing awkward questions to other people, but about mechanically assembling these questions for any given topic, which we can then ask ourselves.

3fubarobfusco10y

A number is anything that acts numbery under certain operations. Integers are very numbery. Reals are pretty numbery. Polynomials and matrices are still pretty numbery. Strings and graphs are somewhat less numbery. Rubber chickens are scarcely numbery at all. "What is a mathematical operation?" is maybe a better question.

0sixes_and_sevens10y

Inspired by this, I am going to come up with an amazing new philosophical theory of truth based on Perl.

2ChristianKl10y

I'm not sure this has something to do with Imaginary expertise. If you ask a 10 year old kid what money happens to be, it probably gives you a straightforward answer. On the other hand an expert might understand flaws of various different definitions of money and therefore won't give you a straightforward answer.

4sixes_and_sevens10y

This isn't about whether or not one can provide a straightforward answer. It's whether or not one is even aware that the question has a non-obvious answer. Saying "actually, that's a complicated question" is a more virtuous answer than providing some unsubstantiated, ad-hoc response that falls apart under the slightest scrutiny. It most poignantly ties in with imaginary expertise as both arise from the illusion of explanatory depth, (i.e. "I am familiar with this, therefore I understand it")

Hm. If I had to give an answer, I'd say it's the stuff that's conserved because the laws of physics don't change over time. But that's pretty theoretical - maybe an extensional definition would be better.

It is variously said that we share 99% of our genes with a chimpanzee, 95% of our genes with a random human, and 50% of our genes with a sibling. Explain how these can all be true statements.

6ChristianKl10y

Without wanting to claim complete coverage of the subject, let me talk about a few relevant issues:: Let's look at what's the word 'gene' supposed to mean in the first place. A while back there was the belief that DNA mainly exists to be translated into proteins. A gene was supposed to be a sequence that's translated into a protein. Today we now that a lot of DNA exists to be translated into RNA without producing proteins. Depending on the circumstance you might count RNA producing DNA as genes or not. When you take a string of DNA that can produce a protein it's possible that different splicing on introns produces a different protein. Humans seem to have something between 20000 and 25000 protein coding genes but >100,000 proteins. That drastic difference in numbers was a surprise to everyone when we did the human genome project. There seem to be multiple copies of some genes. It's not clear whether you count them multiple times and you can't count repetitions in DNA well because we sequence DNA via shotgun sequencing. If you compare the gene for human insulin with the one for champanzee insulin you can count it as both having insulin. You could use the match score between human insulin and champanzee insulin. You could say that it's a different gene because it's not exactly the same. In the last case you have to think about what "the same" mean. Is it enough that the same protein gets produced or do you also want the exact same DNA? There are 64 different 3 base pair combination and only 20 (+1) different amino acids, so some amino acids get encoded by multiple base pairs. Those changes could however change the amount of protein that get's produced. When producing human insulin in the lab one for example switches those base pairs to maximize protein production. Lastly it's not quite clear which DNA sequences actually get translated into proteins. One test is to try to let yeast or another organism produce the protein based on the gene and that's expensive. I

6tut10y

99% of our genes have a chimp equivalent and vice versa In 95% of something or other of their genome two random humans have the exact same allele. In the other 5% they are no more similar than a human and a chimp are in the 99% that are shared between the species. Of the loci where humanity have different alleles two whole siblings have identical alleles. This is a theoretical number for average siblings in a population with no inbreeding or any population structure, actual siblings tend to be much more similar.

4V_V10y

Non-expert there, but here are my two cents: If you sequence your DNA and the DNA of a random chimp, and consider only the substrings that can be identified as genes, and measure string similarity between them, you will get a number between 98% and 99%, depending on the choice of string similarity measure (there are many reasonable choices). Never heard that before. Suppose an unique id tag was attached to all the gene strings in the DNA of each of your parents. Even if the same gene appears in both of your parents, or even if it appears multiple times in the same parent, each instance gets a different id. Then your parents mate and produce you and your sibling. On average, you and your sibling will share 50% of these gene ids. Of course, many of these genes with different ids will be identical strings, hence the genetic similarity measured as in the human-chimp case will be > 99.9%.

2Unknowns10y

Saying this as a non-expert, the percentages are obviously taken over different gene pools (e.g. there is no reason to count genes in common with a chimpanzee when you are comparing two humans or two siblings.)

1gmzamz10y

This confuses me. I find it highly unlikely the average human shares more genes with a chimpanzee than another human and even more unlikely that siblings only share 50% of their genes. probability estimates (statement is true): * 99% genetic similarity to a chimpanzee = 75% * 95% genetic similarity to a random human = a low nonzero number * 50% genetic similarity to a sibling = 0% * 95% genetic similarity to a random human given 99% genetic similarity to a chimp = 0% I am going to research this. EDIT: findings: 1. Researching an an actual number is exceeding difficult. About 50% of the pages are non-secular websites (this may be my non-optimized google searching). The rest are a mix between technical articles and articles formatted for the average human (average being living in a English speaking and developed nations). 2. 99% genetic similarity to a chimpanzee Mostly correct. Estimates range between 95%^[1] and 98.8%^[2] * 95% genetic similarity to a random human Incorrect. Estimates are at 0.1%^[1]. I did not notice other numbers. * 50% genetic similarity to a sibling Incorrect as you stated it (comparing total gene dissimilarity). You might want to reword it since you were probably comparing what percentage of gene can be attributed to a parent.

4Richard_Kennaway10y

It puzzles me as well. I believe the answer is that there are multiple concepts of "shared genes", but I have never been clear what they are.

0Dahlen10y

That depends on the meaning of "our". A smaller and smaller subset of genes is being considered, as you shift focus from chimp to human to sibling. In the chimp example, the statistic may as well have been made for your entire genome, including stuff like genes coding for cell membrane (which doesn't vary wildly with species/taxonomy, more likely to vary with tissue type -- don't know, not a biologist). In the sibling example, you take for granted that the greatest part of your genome is going to be shared by virtue of both of you being human, exclude those genes, and only count the rest. If you establish similarity/difference by counting the same set of genes (for instance all of them, like with chimps), the difference between you and your sibling might only differ by very, very few percentage points down from 100%, and that's not exactly telling us anything useful, is it? At least this is how I understand it, and why that type of sentence doesn't confuse me. Again, not a biologist, sorry for possible stupid mistakes/inaccuracies.

0Ilverin the Stupid and Offensive10y

Disclaimer: Not remotely an expert at biology, but I will try to explain. One can think of the word "gene" as having multiple related uses. Use 1: "Genotype". Even if we have different color hair, we likely both have the same "gene" for hair which could be considered shared with chimpanzees. If you could re-write DNA nucleobases, you could change your hair color without changing the gene itself, you would merely be changing the "gene encoding". The word "genotype" refers to a "function" which takes in a "gene encoding" and outputs a "gene phenotype" Use 2: "Gene phenotype". If we both have the same color hair, we would have the same "Gene phenotype". Suppose the genotype for hair is a gene that uses simple dominance. In this case, we could have the same phenotype even with different gene encodings. Suppose you have the gene encoding "BB" whereas I have the gene encoding "Bb". In this case, we could both have black hair, the same "Gene phenotype", but have different "Gene encodings". Use 3: "Gene encoding". If we have different color hair, then we have different gene encodings (but we have the same "genotype" as described in "Use 1"). This "gene encoding" is commonly not shared between siblings and less commonly shared between species. So "we share 99% of our genes with a chimpanzee" likely refers to "Genotype". "95% of our genes with a random human" likely refers to "Gene phenotype". "50% of our genes with a sibling" likely refers to "Gene encoding".

2DanielLC10y

Exactly. You have to be an expert in order to know about all of the edge-cases that make definitions difficult.

1NancyLebovitz10y

Try it-- "species" is definitely messy.

5solipsist10y

Off the top of my head, "A collection of organisms which can interbreed with each other and produce fertile offspring", for sexual organisms, and "what humans decide is a species" for asexual organisms. Would an expert be able to do better? The word seems too old and the concept to vague to have a tight definition.

5IlyaShpitser10y

"Species" is not a clean concept in a world with viruses, clines, and ring species. More precisely, "species" is a map marker made by someone who likes discrete, mostly tree-like maps (legacy of Aristotle?)

3faul_sname10y

"Species" is one rung on the phylogenetic ladder. Whether a given edge case should be classified as a species or as a subspecies can be debated, but in practical terms it is useful to have a tree-like map, because it allows you to assess the phylogenetic distance between two groups. Also, compared to the range from class to genus, "species" is relatively clear-cut.

0ChristianKl10y

That works as long as a virus doesn't transfer genes from one species to the next and thus invalidates the tree structure.

1faul_sname10y

It depends on your goal. What a lot of non-biologists don't realize is that the ladder keeps going after species down through subspecies and beyond. In terms of bacteria, which do undergo horizontal gene transfer, we generally refer to them by their strain in addition to their species. The strain tells you where you got the culture, and, in lab settings, what it's used for. CAMP Staphylococcus aureus is used for the CAMP test, for example -- because you know where the strain comes from, you can be reasonably confident that it will behave like other bacteria of that strain. If you have a different strain of Staphylococcus aureus, you expect that it would probably also work for this test, but by the time you get as far away as Staphylococcus epidermidis, it's quite unlikely that you could use it successfully for the CAMP test. In theory, you could do a DNA extraction and see if your organism has the right genes to do what you want. In practice, it's usually cheaper and easier to use a strain that you know has the right characteristics -- even among bacteria with 20 minute generation times, genetic drift is still pretty slow, and what little selective pressure there is is pushing for the strain to keep its useful properties (i.e. we throw away bad cultures). The phylogenetic tree model is used because it makes useful predictions about the world, not because it represents the way the world actually is.

2ChristianKl10y

Yes. I'm not denying that such models do have use. But on the other hand people outside of biology do often consider them to represent the world as it actually is.

0faul_sname10y

I think we're in agreement here.

0Gunnar_Zarncke10y

Only if you define the tree genetically and not via ancestorship. Trying to go from one approach to the other is bound to be messy.

I think species can be paraphyletic. If we sent a family of llamas into outer space and they evolved into Space Llamas, there would be no common ancestor which included all terrestrial _L. glama_s but excluded L. astrollama.

0ChristianKl10y

There are various genetic issues that make individuals sterile. We don't say that they are suddenly another species just because they are sterile and thus not sexually compatilbe.

0[anonymous]10y

And there are groups (like oribatid mites) where parthenogenesis is very common. No sex at all, though males occur. (Here's a challenge: you think of anything common among vertebrates, then look for invertebrates (including single-cellular animals) for whom it's not common. The sea-dwellers are very good for this search.) Some people would tell you that only Homo sapiens exists as a species. Suppose a 'species' exists as a set of disjointed populations, which will never meet each other (or the probability of it happening is so much smaller than of them going extinct)...

0tut10y

No, that's a clade or a monophyletic taxon. Most species are clades, but as solipsist points out not all species are necessarily clades, and most clades are not species.

No, it's more specific because of based on criteria like "sexual compatibility of descendants".

I appreciate your reasoning, but... First, I assume this exchange takes place among a group (part of my personal definition of “mouthing off”). I further assume that your goal is to disparage the “pseudo-blowhard”. Given these assumptions, your strategy can only succeed if you “blank” the pseudo-blowhard AND if the group doesn’t believe your question is trivial AND ALSO if the group does not confuse this blanking with a reasonable reaction to a surprisingly difficult question. I think the odds are against you. Furthermore, if you do not succeed, I predict the group will think less of you. Your question will seem like a waste of time, an unwelcome redirection of the conversation, or a lame attempt to express your disagreement with the speaker.

I like 'what is a statistic?" and "what exactly is money?". I'm not sure how I feel about "what exactly are numbers?", though.

It's a messy term that doesn't correspond to any simple territory as far as I'm aware.

[-]iarwain110y110

I recently started reading up on the standard approaches to epistemology. Much of the primary discussion seems to be focused on the question "what constitutes knowledge?". The basic definition used to be that to count as knowledge it needs to be a belief, it needs to be justified, and it needs to be true. But there's the Gettier Problem which points out that there are cases that satisfy the above criteria but which we wouldn't normally consider "knowledge". Numerous alternative "theories of knowledge" have been proposed, new counter-examples have been pointed out, philosophers have split into competing camps (each under its own "-ism" title), and hundreds if not thousands of papers have been published on this topic.

But I'm totally confused. It sounds like they're just arguing about basically arbitrary definitions. So agree on a definition and get on with it. Or define different types of knowledge if that suits you better. And if that doesn't perfectly capture everything we might mean by the word "knowledge", what difference does it make? If they'd taboo the word "knowledge" would there be anything left to discuss?

I assume I'm just missing something. But if in fact they could just taboo the term and get on with more important discussions, then could someone please explain to me why so many highly intelligent, extremely thoughtful philosophers have spent so much time on a (seemingly) ridiculous discussion?

9Stefan_Schubert10y

I agree with this. However, there are philosophers who criticize this practice. For instance, Peter Unger recently published a vehement criticism of mainstream analytic philosophy, Empty Ideas. One influential view is that we should not try to "analyze" pre-theoretical concepts, but rather construct fruitful, exact and simple "explications". If you have that view, definitions do not become interesting for their own sake. Rather, terms and concepts are a tool in the pursuit of knowledge, which can be more or less effective. See Carnap's dicussion in Logical Foundations of Probability, pp. 3-20 (esp. p. 7). That said, it is true that many philosophers continue to write papers on the Gettier problem in a very classical essentialist fashion, along the lines you are describing. The same goes for many other philosophical discussions (e.g. on truth, reasons, etc). I think that there is a selection effect at work here: those who think this is silly move on to other things while those who think that it isn't keep on doing it. This creates the illusion that more people think this is a good and interesting form of philosophy than is actually the case. Of course now and again some outsiders get so fed up with this that they write a book on it to attack it. Another similar example of this (in addition to Unger) is Ladyman and Ross's attack on mainstream analytic metaphysics (which treats questions like "is the statue and the lump of clay that is made of distinct or identical objects?). I suspect that many others feel, however, that although this kind of philosophy is a bit of a nuisance, there are other more pressing problems more worth focusing on. For instance, I suspect Nick Bostrom doesn't like this kind of philosophy, but as far as I know he hasn't spent much time criticizing it, thinking there are other problems which are more important to spend time on. Also, it seems surprisingly hard to weed out. The kind of criticism that Carnap gave is at least a century old, but

2ChristianKl10y

Do you think the question whether or not core foundations of analytical philosophy are correct is unimportant?

1Stefan_Schubert10y

No, though I understand my comment could be read in that way. I have thought and read a lot about these questions (and written some things) and sometimes get a bit frustrated with them. I have started to become more pessimistic about the possibilities of convincing mainstream philosophers who like to work on these questions ("scholasticism with a dull knife", as a brilliant colleague of mine scribbled on his noteblock during a talk on the Gettier problem). Perhaps we should instead focus on showing what alternative things philosophers could do. Also we should make alliances with other subjects. People outside the discipline are much more likely to want to fund work on business ethics or medical ethics than yet another go at some concept or metaphysical question. I think this view of Matti Eklund's has a lot to be said for it: If we can't disprove the Gettier stuff, perhaps we can hope that people will get bored of it (if we provide them with a less boring alternative).

1ChristianKl10y

When you can't disprove something the straightforward way is to accept it. In this case you can switch to a more construtivist notion of knowledge. To quote Heinz von Förster: "Truth is the invention of a liar." The problem isn't that you can't do anything useful with ontology but that a lot of analytic philosophers are confused about the subject and produce papers that provide no value. Barry Smith does deal with the question of knowledge and get's funded because he actually does something useful. Applied ontology is useful for bioinformatics and other fields likely also would profit from it. It possible that in one or two decades bioinformatic inspired mapping of mental states is good enough that the psychology folks with their DSM simply loses it's authority.

6Shmi10y

That has been my exact reaction to most of the "big" questions, with a few exceptions. As for the "justified true belief" "definition", each word in it is already so poorly defined, you might as well give up on it. My personal working definition of knowledge is the capability to accurately predict the outcome(s) of a certain (set of) action(s). Which probably matches an existing camp or two, not that I care.

5ChristianKl10y

Yes. If we want to have an AI that knows things we have to be specific about what knowledge is. If we have unrealistic naive concepts we will never get the knowledge into the AI. If you want an university to teach knowledge, then it makes sense to have an idea of what the university is supposed to teach. If you want to decide whether someone has depression, than it makes sense to ask what you mean with the sentence: "Alice has depression." Currently it might mean: "A trained psychologist has found that Alice fulfills the criteria of the DSM-V for depression." It would be possible to get saner way to deal with the issue if we would have a better grasp on the underlying ontology. Based on certain ideas of knowledge people reject certain approaches as pseudoscience because they don't fulfill the criteria of what's believed to be necessary for knowledge generation.

4crazy8810y

Yes, philosophers tend to be interested in the issue of conceptual analysis. Different philosophers will have a different understanding of what conceptual analysis is but one story goes something like the following. First, we start out with a rough, intuitive sense of the concepts that we use and this gives us a series of criteria for each concept (perhaps with free will one criteria would be that it relates to moral responsibility in some way and another would be it relates to the ability to do otherwise in some way). Then we try to find a more precise account of the concept that does the best (though not necessarily perfect) job of satisfying these criteria. I personally find the level of focus on conceptual analysis in philosophy frustrating so I'm not sure that I can do justice to a defence of it. I know many very intelligent people who think it is indispensible to our reasoning though so it may well be deserving of further reflection. If you're interested in such reflection I suggest that you read Frank Jacksons, "From Metaphysics to Ethics: A Defence of Conceptual Analysis". It's a short book and gives a good sense of how contemporary philosophers think about conceptual analysis (in terms of what conceptual analysis is, btw, Jackson says the following: "The short answer is that conceptual analysis is the very business of addressing when and whether a story told in one vocabulary is made true by one told in some allegedly more fundamental vocabulary.") Off the top of my head, why might someone think conceptual analysis is important? First, conceptual analysis is all about getting clear on our terms. If you're discussing free will, it seems like a really bad idea to just debate without making clear what you mean by free will. So it seems useful to get clear on our terms. Myself, I'm tempted to say we should get clear on our terms by stipulation (though note that even this involves a small amount of conceptual analysis or I would be just as likely to stipulate

SIA/anthropics strike again? "Fantastically Wrong: The Scientist Who Thought 22 Trillion Aliens Live in Our Solar System":

Here’s what [Thomas] Dick figured. At the time, there were an average of 280 people per square mile in England. And because he thought every surface of our universe bears life, it would naturally occur at roughly the same population density. So from comets and asteroids to the rings of Saturn, if you knew how big something was, you could guess how many beings live there. Thus, Jupiter would be the most populated object in the solar system, with 7 trillion beings. The least populated would be Vesta, the second largest asteroid in the asteroid belt, tallying just 64 million.
Dick, you see, was a very religious man, but also a voracious scientist, one of the last of the so-called natural theologists, who looked for signs of God’s influence in nature. For Dick, it simply did not make sense for God to have created the cosmos just to have it sit around unoccupied.

Well, that's kind of close. The average density of Saturn is in fact less than that of water, and the gravity at its cloudtops is only very slightly higher than at Earth's surface. Jupiter's isn't that bad, either, at ~2.5g.

2gwern10y

Sure, but that's not impressive and you'd expect him to be close to right about those numbers. As I understand it, it's pretty easy to derive the volume of planets from optical observations of diameter, and the mass from their orbits & Newtonian mechanics, and then divide to get net density.

In the spirit of asking personal questions on Less Wrong I'd be pleased if some of the community's brainpower could be directed in my direction. (It's a minor problem.)

After about a year of being unemployed, I found a job (hooray), but it's not a job I want to do for a long time. This means looking for a new job, but due to the long and unpredictable hours of my current job I'm left without time to look for a new job. The time away from the job is spend, in decreasing order: sleeping, quality time with girlfriend, internet, food and personal entertainment/projects. As it stands, I don't feel like I can touch either of the non-work activities without going insane, or at least not to an extent where I can shave of an hour to allocate to looking for a new job (I know from previous experience that doing it for less than an hour doesn't result in anything) without going insane.

Current options (I can see):

In So Good They Can't Ignore You, Cal Newport argues that the path to enjoying a job goes primarily through being good at that job, not liking the job when first starting it. I suspect there is much to be gained by devoting yourself to your current job and getting good at it. Even if you transition to another job, the self-control and emotional maturity you learn by doing this is likely to transfer. (He also argues that it's better to be in a field where quality is detectable and valuable; if you're doing commodity work, than being especially good is unlikely to get you far. But I think there's a psychological component as well: it is highly likely your coworkers and employers can detect a shift from disliking the job to liking the job, and you might be surprised at how much that transition will get you in terms of respect and power on the job.)

2MathiasZaman10y

Sounds like reasonable advice, but my reasons for not wanting the stick with the job have less to do with my enjoyment of it and more with it it not being something I'm talented at/uses the skills I'm good at, it isn't a direction I want to go with nor is it very high-paying. I like the job just fine and want to do it properly (to an extent), I'd just enjoy doing something else more.

4chaosmage10y

Look around your current company and see if there's another job in there you'd like better (or which would suck less). Switching jobs inside a company is often easier than switching companies. Ask someone to find a job for you. Family and close friends will often do this for free. Others might if they like you and they trust you'll remember you owe them a favor. Your girlfriend might, because it means you get more time together. Learn how to slack and not get caught. If you're in an office, there are HowTos. If not, you can still determine which parts of your job are safest to slack off at. If you haven't, become friends with someone who has the kind of job you want. If you have, deepen that relationship and ask to be introduced to similar friends. As long as you never directly beg for a job, it is perfectly alright to say you're looking for a job in that area. All of this is assuming that one year of unemployment was entirely due to factors outside your control. This is very unlikely. You could almost certainly raise your employability in lots of ways that you haven't used. Move to a place with a better job market for example, dress better (to use the Halo effect), or whatever it is - basically remove some of the differences between you and the kind of person who gets the job you want. For more advice, be a lot more specific about your situation. What kind of job do you want, why don't you have it, how much are you willing to sacrifice to get it?

Thanks for the advice. I love how Less Wrong is a place where you can say you want to slack at work and someone points you to a good resource for doing so :-) Changing job within the company isn't an option, due to it being a small cultural non-profit that mostly works with freelance artists.

If you're interested in IT, talk to someone in your area working in IT about the options for somebody without a degree in IT to get a job in that field. In the US at least, there are a number of mini certifications that would take a lot less than 3 years. Similarly, you should explore a variety of more easily obtained technical vocations. I am not sure what the options in Belgium are. 3 years spent towards only a slight improvement sounds like a negative return on investment.

Are you sure cutting 15 minutes from each of the four non-work things would make you go insane?

-3dxu10y

How many hours of sleep do you get per day, on average? That seems to me the most plausible option here to cut down on without suffering any psychological or emotional effects, although of course if you're not getting much sleep as it is, it's probably best not to go with this idea. At any rate, if you sleep roughly 8 to 10 hours a day, do you think you could cut down on sleeping for maybe an hour or so, possibly by setting an alarm, or is that unfeasible?

1Gondolinian10y

There're also biphasic and dual core sleep schedules which may reduce the need for sleep to ~6 hours total per day. I believe Yvain uses something like this. (ETA: It seems he does have a biphasic sleep schedule, but it's 8 hours total. (double ETA: source)) As I understand it, more extreme polyphasic sleep schedules are difficult to get into to say the least and aren't compatible with mainstream work schedules.

1dxu10y

Excellent point, although you are correct about the difficulty of integrating such a sleep schedule into a regular work schedule. The diagrams in the Wikipedia article, however, seem to imply that sleep episodes need to be more or less equally spaced. Is this always the case? If not, it might be possible to "shift" a nap a little bit earlier or later in order to accommodate a full-sized workday.

1Gondolinian10y

Something like the Everyman would likely work if Mathias could take a nap during his lunch break. (If it's a short break, he could simultaneously try out intermittent fasting. :)) I also imagine the 20-minute nap biphasic would tolerate his waiting until the late afternoon to take the nap. I don't know about the others, perhaps someone with polyphasic sleep experience could weigh-in?

0MathiasZaman10y

I sleep between 6 and 7 hours a day and that's already stretching my ability to deal with that. Biphasic sleep put too much strain on my relationship, so unless something changes in that area (and I hope it doesn't) that option is also out.

[-]protest_boy10y70

I have a question about a seemingly complex social issue, so I'm interested if anyone has any insights.

Do protests actually work? Are e.g. the Ferguson/police crime protests a good way of attacking the problem? They seem to me to have a high cost, to be deflecting from the actual problem, and not enough sustained effort by people who care to push through to actual social change in the U.S.

7Sarunas10y

According to Stephen Pinker, protests can turn individual knowledge into mutual knowledge This suggests that protests may lead to something in a particular case when most people already have individual knowledge, but they do not have mutual knowledge yet. For example, suppose those people really care about some issue and have idea what to do, then if participating in protests is risky, that signals that all those protesters are willing to take risks in order to achieve their goal (curiously, in this particular case, if protesting is safe (as it is in most Western countries), the signal might be less clear). This way individual knowledge becomes mutual knowledge. So if it is the lack of mutual knowledge that prevents their goals from being achieved, then protests might help. Otherwise, if it is something else that prevents solution (e.g.lack of idea how to solve a problem, various game theoretic (or coordination) problems that are not solved by going from individual to mutual knowledge, etc.) from being achieved, they are probably much more likely to be useless.

3Ixiel10y

In my area, protests are largely social gatherings of like minded people. I asked protesters on three occasions last year and only two of a couple dozen protesters thought they were reaching an audience that does not already agree. I stress this was not a scientific study, but at least average for anecdote.

3Lumifer10y

You need to define your goals. Do protests work to achieve what?

3LizzardWizzard10y

Em..change in policy I suppose, isn't all this protest business about it?

6Lumifer10y

Which "change in policy" do Eric Garner protests aim to achieve? A rewriting of how indictment or grand juries work? Which "change in policy" did Occupy aim to achieve?

3protest_boy10y

I think that's one issue with protests. Many people gather with ill defined goals that are tangentially related to what most would agree is the actual problem. The "actual problem" for Occupy relates to unequal distribution of wealth, and the "actual problem" for the recent police brutality protests relates to systemic bias in the criminal justice system. I'm not sure if there actually is this sort of systemic bias, nor am I sure of the implicit claim that "things have gotten worse." So, what do protests actually achieve, and is that effective in making things better? It seems that they do raise some level of awareness in the sense that more eye balls are on the issue for a short period of time. It's unclear to me that that's effective though, especially since it's a double edged sword. Raising awareness about the issue makes the negative externalities (like rioting and looting) more likely to be picked up and emphasized about the media.

3Lumifer10y

A recent Yvain blog post might be helpful.

3Bugmaster10y

I was wondering that too; personally, I have no idea how to even begin answering the question. It would seem that at least some protests do work, as evidenced by the civil rights movement during the Martin Luther King era; but I don't know if this is true in general.

2knb10y

I think protests work if there is already a critical or near-critical mass of support in the relevant decision-making body (legislature, courts, civil service, etc.) Protests rarely change minds, but they can give already-sympathetic people a new impetus to take action in this area rather than another. ETA: It also helps if the protesters have specific, focused demands, like "end segregation," or "bring the troops home."

What problem? That Blacks aren't free to steal from and intimidate Asian store owners and then charge at a police officer going for his gun?

7RowanE10y

Whether the protesters are trying to solve a problem that actually exists is entirely irrelevant to the question of whether protests work, and you're making your irrelevant point in an extremely confrontational red-tribe-blue-tribe way. This is exactly what the whole "politics is the mind-killer" thing is about, and doesn't belong here.

4Lumifer10y

How so? If the problem doesn't actually exist, the protests are guaranteed to NOT work. They might have a variety of different consequences but they cannot work in the sense of solving that problem.

4RowanE10y

I meant that whether these specific protesters are attacking a non-existent problem isn't relevant to the effectiveness of protesters in general. One could make an argument that there's a more general tendency for protesters to attack problems that don't really exist and therefore can't be solved, as a reason why protest is generally ineffective, but I'm pretty sure alienist wasn't doing that.

0Lumifer10y

There is no good answer to the question of the effectiveness of protesters in general. The answer will always be "It depends".

3bogus10y

I disagree. alienist's answer was a bit flippant, but he's pointing out a real issue. If we're not even sure that there is a problem to be solved, how can we assess what protests are supposed to achieve? His links discuss newly-released grand-jury testimony (among other things) that is significant evidence, and should rationally lead us to alter our views of the Ferguson incident.

-2alienist10y

Well, in the parent I listed one potential "problem" that the protests were trying to "solve". You might not think of it as a problem (and I would agree), but at least some of the protesters seem to. In any case the protests probably have in fact helped to "solve" that problem. Given what happened to Officer Wilson, many cops are going to decide that they don't want to risk being the target of the next "anti-racist" media circus/protests and simply avoid policing black neighborhoods.

I've noticed that for many LW posts - and EA posts to a lesser extent - it's very common for a comment on them to get more upvotes than the post itself. Since it's usually a lot harder to write a post than to comment on it, it seems like this isn't incentivising people to post strongly enough.

This also seems to apply to facebook posts and likes in the LW and EA groups.

6Lumifer10y

You don't want to incentivise people to make top-level posts, you want to incentivise them to contribute excellent content, and it doesn't matter much if it's in the top-level post or the comments. The guy who thought the value of the product must reflect the labour that went into it was Karl Marx. He was wrong.

3Vaniver10y

3Lumifer10y

As far as I remember, that's what he got to in the third volume of Das Kapital, but the first volume is very certain that the value of any product is a direct function of the amount of labour that went into it. I think the observation that Marx was a proponent of the Labour Theory of Value is uncontroversial? He didn't invent it, of course, but his name is strongly associated with it.

2Vaniver10y

I'll have to wait until I get home to find the relevant section in my copy* to make sure I haven't misremembered it, but as I recall he claims a widget's value is lower bounded in the long run by the cost of labor because otherwise that laborer will starve / switch to doing something else. That qualifier is very important, as with it the statement is a correct observation about equilibria, and without it the statement is an incorrect empirical claim (people can make mistakes and misinvest resources in the short run) that typically takes on a prescriptive or moralistic flavor. * It's been a long time since I read Marx for a reason. I'm not seeing it in the 40 pages I was expecting it to be in, so who knows if it's there.

1Lumifer10y

Well, thanks to the magic of the 'net let me quote from Volume 1: I think Marx is quite clear on what he believes creates the value of the product.

3Vaniver10y

I think the first part of that sentence is very dangerous: Marx does not use the writing style most modern readers of English are used to. For example, "plainly" can be either read as stating that the underlying reality is as simple as the description (as I think most moderns would interpret that sentence) xor that the underlying reality is less simple than the description (as most moderns would interpret that sentence if he used "simplistically" or "naively" instead). I'm moderately confident that the second case is the intended one: in the first volume, Marx makes a sketch, that he then refines again and again and again in the volumes to follow, and so to call him "very certain" of the sketch in the first volume is misreading him (or, at least, misrepresenting him). All Marx is doing here is acknowledging that all commodities can be traded for each other, and that means there is some idea of a 'common standard of exchange-value,' and the obvious 'natural currency' in which to express exchange values is a sort of generalized human time. Consider this section a few pages later: The following section also serves as evidence that he is using generalized human labor just as a reference for prices: To step back, Marx spends several pages discussing the difference between "Use value" and "exchange value"- the first is what we call 'utility,' and the second 'price,' and Marx typically uses "value" to refer to "exchange value"- consider this paragraph:

2Lumifer10y

All that feels a bit too post-modern to me :-/ Even if Marx's thinking changed in between Vol 1 and Vol 3, that's not a good thing for the theory and cherry-picking is still cherry-picking. Without going into what Marx really believed, let me just point out that the labour theory of value is widely accepted by Marxists (those that still remain) as the correct one, see e.g. here.

0Vaniver10y

! The point isn't that Marx changed his mind, but that, among other communication problems, he makes many broad statements and then carves away caveats, either afterwards or in some definition elsewhere (that hopefully you've remembered correctly). For this particular example, though, consider the paragraph that you cut out with an elipsis: This is an explicit disavowal of the simplest possible interpretation of the labor theory of value, the claim that "labor in = value out." The 'labor' he's talking about isn't actual labor, but hypothetical generalized labor, and it basically exists just to be a natural currency. Sure, and I agreed on that point up here. LTV, as I see it, runs into huge Motte and Bailey problems, where the actual theory is inoffensive as a "dollar theory of price," in which the 'price' of a commodity is the 'number of dollars it costs', but the conclusions people want to use it for are "the past doesn't matter, everyone owns everything!" As far as I can tell, though, Marx stayed in the motte, and this is where the "I'm not a Marxist" statement comes from.

2Lumifer10y

Which makes his thesis kinda hard to pin down, doesn't it? So what precise, hard, falsifiable statements about the nature of value of a good does Marx make, you think? That's not inoffensive at all. There is a great divide between thinking the value comes from the supply side and thinking the value comes from the demand side. The theory is inoffensive if you make it say nothing useful, but that's not how it has been read. Did he now? You think he didn't make any connections between the LTV and his characterization of the bourgeoisie as parasites inasmuch all the value is created by the labour of the workers?

3Jabberslythe10y

I think that people making more top level posts makes the community better off. I think that a new post that someone has put work into tends to be a lot better content overall than the top comment that might just be stating what everyone else's immediate thought about this was. Top level posts are also important for generating discussion and can be valuable even if they are wrong for that reason (though obvious they are better if they are right).

When is it wrong to enable someone to significantly reduce the quality of their life and thereby significantly increase yours, while remaining happy themselves?

4Jiro10y

Unless the quality of life is reduced because they have a false belief that it would increase, and I can prove to a sufficient degree that that belief is false, I'd say "it's pretty much never wrong". Is it really wrong to get paid for constructing a church if I think organized religion makes people worse off? And I certainly wouldn't want someone applying that principle to me, because I know how bad other people are determining what reduces the quality of my life. It's this logic which leads to large soda bans.

1TheOtherDave10y

I usually approach this sort of question by modeling people as approximations to ideal agents who reliably act in such a way as to actually optimize the world for their own values. If I consider a hypothetical person who very closely approximates that ideal, I'd say it's generally+ not at all wrong to enable them to significantly reduce the quality of their own life... they will either do so, or not, depending on their own values. If I consider the other extreme, a hypothetical person who reliably acts in such a way as to optimize the world for the opposite of their own values, I'd say it's generally+ wrong to enable them to make any effective choices at all. Either way, their happiness is largely irrelevant to me except insofar as it's subsumed in their values, and whether I benefit from their actions is irrelevant. That said: obviously I'm more inclined to motivated cognition when I benefit, and therefore need to be a lot more scrupulous about whether my thinking has gone completely off the rails. There's something to be said for the rule of thumb that if a line of reasoning tells me it's OK for me to act in ways that predictably lower the quality of other people's lives and benefit mine, I should reject that line of reasoning as flawed... not because that's necessarily the case, but because human minds being what they are that's the way to bet. + There are exceptions in cases where I think their values are themselves wrong, but I think that's a different conversation.

In the spirit of Tell culture, I'd like to make known my preference for not being downvoted without a reason given. I'm open to modifying my behavior in response to criticism, but just downvoting something I write doesn't give me much information, and I find it rather unpleasant to know that people disapprove of something I've done, without knowing what I did wrong or what I might be able to do to fix it.

[This comment is no longer endorsed by its author]Reply

[-]Unknowns10y100

I disagree with this sentiment. If anything, giving criticism and downvoting are alternatives, not things that go together. For example, since I don't like this idea I might have just downvoted this comment. But since I'm responding to it I'm not going to do that; it isn't necessary to downvote if I'm going to express my criticism anyway, and most likely it wouldn't be helpful either, since you'd probably just be annoyed by the downvote.

In other words, your comment is basically a criticizing of downvoting in general; if that is a reasonable preference, we should just remove the possibility of downvoting at all.

5dxu10y

My personal downvoting policy is this: I tend to refrain from downvoting unless the comment really is atrocious in a way that I feel ought to be intuitively obvious. This has very little to do with the actual content of the comment and a great deal to do with the presentation; for example, I won't downvote a comment that I disagree with, but I will downvote a comment that I perceive as adding nothing to the discussion. In practice, this means that I do not downvote very often; in the totality of my time here on this site, I believe I've downvoted less than ten comments. The less atrocious comments, however, I neither upvote nor downvote; instead, I write a reply discussing what I disagree with in the comment and what can be done better. (Note that in this case I actually upvoted your comment for being well-written and thoughtful, even though I disagree with your conclusion.) In that sense, my downvoting rationale adheres to your "exclusivity" principle. And yet I feel that downvoting based on pure disagreement, which you appear to be endorsing, is rude and is not a healthy behavior for the community, seeing as it basically serves to provide negative reinforcement every time someone says something contrarian, which is hardly conducive to an atmosphere of cooperative discourse. Comments that you disagree with should be replied to, not downvoted without explanation, unless there's some other factor unrelated to content that caused the downvote. Most of the time, however, when I'm downvoted, I find that I can hardly discern the reason. I strive to make clear comments that express my point concisely without going on for to long, so whatever the reason is, it can't be presentation. Content, then? But if I'm saying something stupid or wrong, I'd very much like to know! Naturally I don't think I am, so if someone randomly downvotes one of my comments without telling me why, I'm forced to either (a) make unsupported speculations about what I'm doing wrong, or (b) disregard

2Unknowns10y

I did not suggest downvoting purely on account of disagreement. It is true that if I had not responded to Gondolinian's comment, I might have downvoted it. But not just because I disagree, but because I find complaints about downvoting unpleasant and would rather see less of them on the site. In general there might be many other reasons for downvoting which do not necessarily involve disagreement, such as vagueness, excessive verbosity, illogical reasoning, and so on. Again, of course you can simply respond and mention those things, but again in that case there is not all that much reason for downvoting at all. The advantage of downvoting is that it takes very little resources and does not require responding to something which may not be worthy of a response. The suggested policy does not necessarily fail, for several reasons: 1) the person may indeed in some cases realize why he is being downvoted; 2) even if he does not, he may speculate randomly and modify his behavior until he is no longer downvoted -- i.e. downvoting provides selective pressure on comments; 3) in some extreme cases, it would be good even if he just becomes less likely to comment at all. In any case, as I said, the point of downvoting is that such a small use of resources is involved that it is not necessary that there be some particular positive effect in every case.

2Gondolinian10y

I'm retracting this because in retrospect, I don't think it was a good idea to post this (I was rather tired when I wrote this--not a state of mind known for its good judgement.), and I'd rather not worry about having this as a potential karma sink.

This doesn't sound like a system that would be easy for less intelligent/educated voters to use. I wouldn't be surprised if it would lead to a number of voters voting for candidates they didn't intend to vote for. Additionally, many more potential voters might refrain from voting at all because of the complexity of the system.

1ike10y

That's why I said a "standard" option would still be available. That would just be a standard vote for one candidate. Also, raising the sanity line for voters might be a net positive ...

1Torgo10y

That would help, but just adding complexities to the act of voting could turn people away (just as offering more possible modes of response to surveys can sometimes decrease response rates). Whether that would be a good thing or a bad thing depends on what the purpose of voting is. If the purpose of voting is to benefit from collective wisdom, perhaps preventing less educated/intelligent voters from voting is a net positive. However, if the purpose of voting is to represent diverse interests in order to more fairly allocate societal resources, than preventing less educated/intelligent voters from voting could leave them less effectively represented.

What if it's neither of those?

Right now, I bet that over 50% of the people who vote in a US presidential general election couldn't explain how the electoral college works, and over 10% think they are voting directly for president (if anyone is less lazy than me and looks up relevant surveys, let me know.) This doesn't stop them from voting. My system would still have the individual candidates on the top, and only advanced voters would even care about going further. Is this really so much more complicated than the electoral system, compared to a direct voting system? I know this has no chance of happening in a real government anytime soon, but I'd still like to talk about it. There are voting systems that are more complex than ones used in "production" and only used privately. (I can't name any off-hand, but I'm not so familiar with voting theory.) Also, if this is more optimal than what's being done now, then we can educate voters, or at least know that it's better so one day when people are ready, we can switch. What led me to this idea was thinking about the National Popular Vote, which only goes into effect if it itself gets a cetain number of votes (or rather, the strategy of the states that adopted it is to do something different if enough other states also do so.)

That depends very much of what you mean with real government. There no reason why the student body of an university can't be persuaded to elect their Student Government President that way. Various open source projects govern themselves through complex processes. LessWrong didn't use an election to pick a moderator but we could have, if we would believe that a democratic process would have been better. If you think you have a system for better governance than it's a mistake to focus mainly on the national level. It's bad to suggest that the national level should switch to a system that hasn't proved it's worth on a smaller scale. As a young and idealist college student who wants to change governance, student self governance is the ideal playground. On the one hand you are facing smart people who have other interests than you, on the other hand you don't mess up too much if you get things wrong.

Many folks' response to advocacy of weird voting systems seems to be something like — "The only reason you would advocate that weird voting system is because it gives your party some sort of sneaky advantage. I don't know enough about voting systems to know what that sneaky advantage is, but I know enough about humans to know that you're up to something."

Have you been in any discussion with practical implications about a voting system, based on which you make that statement or is your experience mainly about talking with people who don't have an influence on actual voting systems?

3fubarobfusco10y

It was, in fact, to do with student government. :)

What kind of pitch did you gave in favor of another voting system? If all you can say is "the math is more beautiful" than that's likely not going to convince anyone.

The electoral college system doesn't require that they look over a long list of conditional responses and select from among them; the complexities are hidden from the voters, as you mention. I don't think the complexity of the electoral college system provides much evidence for how prospective voters would react to a complex system of voting options. Voting systems used privately can be more complex than voting systems for public office because a more educated population may be using them. I'd be more concerned about getting a representative pool of voters than trying to get voters to learn a new more complex system. I don't believe the difficulty of strategic voting is a major problem. On the other hand, I do think that reforms that reduce the cost of voting would be useful, and are being implemented in some states. I like the national popular vote, but the complexities of that idea, like the electoral college, are hidden from voters; I don't think it's comparable to your ballot system.

[META]

It seems like several people are against having a meta sub-thread in the Open Thread. I thought it would be a cool thing to have, I'm provisionally assuming I was wrong. If no one objects, I'll revert back to the norm of not having one in any future OTs I post.

3Gurkenglas10y

But how could you have made this kind of announcement without a meta sub-thread?

3Gondolinian10y

Perhaps I could post a top-level reply with a "[META]" tag at the top?

1DanielLC10y

He could have made it without putting it in a sub-thread.

1MathiasZaman10y

What are the arguments against it?

3Gondolinian10y

Two users downvoted the [META] comment. One of them withdrew their downvote after I posted the grandparent. So not exactly arguments, but there does seem to have been a general preference revealed for not having a meta sub-thread.

2tut10y

I didn't downvote, but one possibility is that they prefer that the meta thread is posted by the first person to post in it rather than at the same time as the open thread. In that case they only downvoted the TLP because the thread was empty/clutter.

2Gondolinian10y

Thanks for the input. Perhaps I could ask that anyone who has a meta comment make a [META] TLP and post their comment as a reply to it? Or should I just not mention it?
