[Charles] Darwin wrote in his autobiography of a habit he called a "golden rule": to immediately write down any observation that seemed inconsistent with his theories--"for I had found by experience that such facts and thoughts were far more apt to escape from the memory than favorable ones."

-Robert Wright, The Moral Animal, p.280

A passion to make the world a better place is a fine reason to study social psychology. Sometimes, however, researchers let their ideals or their political beliefs cloud their judgment, such as in how they interpret their research findings. Social psychology can only be a science if it puts the pursuit of truth above all other goals. When researchers focus on a topic that is politically charged, such as race relations or whether divorce is bad for children, it is important to be extra careful in making sure that all views (perhaps especially disagreeable ones, or ones that go against established prejudices) are considered and that the conclusions from research are truly warranted.

Roy Baumeister & Brad Bushman, Social Psychology and Human Nature, Belmont, 2008, p. 13

-5Lumifer7y

A special technique has been developed in mathematics. This technique, when applied to the real world, is sometimes useful, but can sometimes also lead to self-deception. This technique is called modelling. When constructing a model, the following idealization is made: certain facts which are only known with a certain degree of probability or with a certain degree of accuracy, are considered to be "absolutely" correct and are accepted as "axioms". The sense of this "absoluteness" lies precisely in the fact that we allow ourselves to use these "facts" according to the rules of formal logic, in the process declaring as "theorems" all that we can derive from them.

It is obvious that in any real-life activity it is impossible to wholly rely on such deductions. The reason is at least that the parameters of the studied phenomena are never known absolutely exactly and a small change in parameters (for example, the initial conditions of a process) can totally change the result...

In exactly the same way a small change in axioms (of which we cannot be completely sure) is capable, generally speaking, of leading to completely different conclusi

6emr7yYou can model uncertain parameters within a model as random variables, and then run a large number of simulations to get a distribution of outcomes. Modeling uncertainty between models (of which guessing the distribution of an uncertain parameter is an example) is harder to handle formally. But overall, it's not difficult to improve on the naive guess-the-exact-values-and-predict method.
7Epictetus7yThe usual error analysis provides an estimate of an error in the result in terms of error in the parameters. Any experiment used to test a model is going to rely on this kind of error analysis to determine whether the result of the experiment lies within the estimated error of the prediction given the uncertainty in the measured parameters. For example, for an inverse-square law (like Newtonian gravity) you could perturb the separation distance by a quantity epsilon, expand in a Taylor series with respect to epsilon, and apply Taylor's theorem to get an upper bound on the error in the prediction given an error in the measurement of the separation distance. Statistical methods could be used should such analysis prove intractable. The issue that the author refers to is where the model exhibits chaotic behavior and a very small error in the measurement could cause a huge error in the result. This kind of behavior renders any long-term predictions completely unreliable. In the words of Edward Lorenz:

Focus on what something does, rather than what it is.

-- Joshua Engel, Quora

I consider as lovers of books not those who keep their books hidden in their store-chests and never handle them, but those who, by nightly as well as daily use thumb them, batter them, wear them out, who fill out all the margins with annotations of many kinds, and who prefer the marks of a fault they have erased to a neat copy full of faults.

Erasmus, Letter to an unidentified friend (1489)

7fortyeridania7yWhat is the relationship to rationality? This seems simply to be a cheer for reading and a jeer for pretentious book-collecting.

Reread the quote. Erasmus isn't just talking about reading. There are multiple relations:

  • Knowledge is useless sitting there untouched you have to actively make use of it.
  • to truly understand something you have to make that knowledge your own, write down things, make annotations, work through examples, read and reread the book. You can't just absorb the knowledge by skimming through.
  • There are lost purposes here. How many people have books just to look cultured, or read books just to say they have read them. Think of all the famous unread books or Gatsby's famous library.

I agree with each of your bullet points, and they do help clarify the Erasmus quotation's relationship to rationality. Thanks.

Dilbert

Hypocrisy doesn't bother me. Everyone's got his ideal, and then the reality of what he can actually deliver. Scratch hypocrisy, and you're more likely to lose the ideal than the reality.

Milo Behr, Beowulf: A Bloody Calculus.

Hypocrisy does not mean falling short of one's ideals. It means only pretending to hold them.

4Kindly7yI think the same point still applies. I might pretend to hold grandiose ideals by accomplishing some small things in their support. Call me out on it, and I have no further reason to continue doing those small things.
7HalMorris7yTo criticize hypocrisy in debate you don't even have to understand the other's argument -- you only have to be able to find a logical contradiction, and you can always find a contradiction, or something you can plausibly claim is a contradiction. For the debater, it may be very hard to give up. Many of us can find (or generate plausible arguments for) contradictions with 10% of your brain power, thus keeping the other on the defensive, while using the rest of ones mind to search for a deeper argument. But for this reason it makes for tedious unilluminating debate, and ought to be given less encouragement than it gets - that is, if we want more insightful argument.
3torekp7yDaniel Dennett has a very similar remark in Elbow Room, to the effect that hypocrisy is the clutch of moral motivation. Paraphrasing: Use too much, and you go nowhere, but too little, and you're lugging the engine.
1maxikov7yHypocrisy isn't actually fundamentally wrong, even is deliberate. The idea that it's bad is a final yet arbitrary value that has to be taught to humans. Many religions contain the Golden Rule, which boils down to "don't be a hypocrite", and this is exactly an indicator [http://slatestarcodex.com/2013/04/11/read-history-of-philosophy-backwards/] that is was highly non-obvious before it permeated our culture.
2CCC7yHypocrisy means that what you are signalling is not reality. It doesn't harm you, directly; but it does, potentially, and in general, harm anyone who relies on your signalling. Therefore, in a sufficiently large and inter-connected society, the society will be more successful if hypocrisy is given some significant negatives, like social ostracisation for known hypocrites (that also cuts down on the potential damage radius). Therefore, societies which punish hypocrisy will, on average, be more successful than societies which do not. So I don't think that the idea that hypocrisy is bad is arbitrary. It might not be obvious, but it's not arbitrary.
6RichardKennaway7yIt is totally obvious. No-one wants to be lied to, and no-one wants to be found out lying.
0undermind7yLove it -- mainly because it invokes one of my favourite paradoxes. If you preach hypocrisy, and you are in fact hypocritical, than you're not a hypocrite. And if you aren't a hypocrite, then you are.
3DanielLC7yThe paradox arises only if you aren't hypocritical about anything else.
0dxu7yHence why Russell's paradox [http://en.wikipedia.org/wiki/Russell%27s_paradox] makes reference to the set of all sets that do not contain themselves, rather than just some sets that don't contain themselves. (Now, of course, mathematicians don't use naive set theory anymore, but ZFC, which solves the problem.)

On the dispersing of memes (note: politicised).

The reason that millions of people read books about Islam (even if they don't believe in it) instead of studying Cosmology is that cosmologist don't go around blowing up train stations, turning school girls into sex slaves, executing cartoonists, and crashing airplanes into skyscrapers. The reason why we are having a worldwide discussion about one of the most ridiculous superstitions in the history of humankind (to depict or not to depict a man who lived in the 7th century) is that people get killed because of that superstition.

-Piero Scaruffi

cosmologist don't go around blowing up train stations

First thing I thought at this point was "Oh! Maybe we should," then I remembered that I'm not aware of anybody who's studied mathematics thanks to Ted Kaczynski.

Also, you know, blowing up train stations.

"Suppose you ask your friend Naomi to roll a die without letting you see the result... Having rolled the die Naomi must write down the result on a piece of paper (without showing you) and place it in an envelope...

So some people are happy to accept that there is genuine uncertainty about the number before it is thrown (because its existence is ‘not a fact’), but not after it is thrown. This is despite the fact that our knowledge of the number after it is thrown is as incomplete as it was before."

  • Risk Assessment and Decision Analysis with Bayesian Networks, Norman Fenton and Martin Neil, Chapter 1
2anandjeyahar7yAh.... "genuine uncertainty" the term reminds me of "no true scotsman argument". My point being, there's an uncertainty reduction before and after the die was rolled, not to say this means, I should update my belief about the die's rolled/winning value. Simply put my friend Naomi's beliefs have been updated and uncertainty in her mind has been eliminated. I think the author was trying to point out that most people conflate the two differences. It definitely is well worded for rhetoric, but not for pedagogy(in Feynman sense).
0Davidmanheim7yWhat does it mean to have uncertainty reduction taking place outside of the frame of reference of the person being asked for a decision? In other terms, the discussion would have been the same if they replaced Naomi with a camera that is automatically used to take a picture.
0anandjeyahar7yYou're assuming humans are rational(as in the AI definition of a rational agent). We're not. So this knowledge that other person knows something for sure, that we don't know about, colours/biases one's judgement. I am not saying one should update their beliefs based on another person knowing or not knowing, but that we do anyway, as part of perception. I would argue, that we should be learning to notice the confusion between the rational side of us vs the perceptive side which notes (the other agent's) confidence/lack there of. I know it is a hand-wavy explanation, but my point stands nevertheless. I agree with the OP that one shouldn't update their beliefs on the basis of Naomi/camera having no certainty about the outcome(of coin toss). Simply say that if it is Naomi, there could be cases where it is rational to update, though hard to actually observe/be-aware of these updations and therefore, safer to not update.
0Davidmanheim7yOK, so "there could be cases where it is rational to update." How would you do so? (I can't understand what an update could reasonably change. You aren't going to make the probability of any particular side more than 1/6, so what is the new probability?)
0anandjeyahar7y(I can't understand what an update could reasonably change. You aren't going to make the probability of any particular side more than 1/6, so what is the new probability?) I don't know either. I can make up a scenario, based on a series of die throws, history of win-losses and guesses based on that, but that would simply be conjecture, and still may not produce a reasonable process. However, this discussion reminded me of a scene in HPMOR. (The scene where HP's critic part judges that Miss Camblebunker was not a Doctor, but an actor. (After Bellatrix is broken out of prison.))
0Davidmanheim7yMy claim is that you can't come up with such a conjecture where it makes sense to change the probability away from 1/6. That is why you should not update.
-1anandjeyahar7yI disagree. I'm not sure it's provable(maybe in professional poker players??), but if you've played the bet a lot of times, you could have come up with cues* about whether your friend has got the same roll(or number on the die) as the last time or not. * -- not sure how verbalizable or not it is .(which implies harder to teach to someone else).
1Davidmanheim7ySo you should update after you see that she rolled some number, and saw her reaction - but this says nothing about updating again because she wrote the number down,

it helps to be on board with the quasi-positivist idea that the sets of things that can and can’t be done, by any experiment, are not just random collections of engineering details; rather, they’re the scaffolding on which we need to construct our understanding of what’s real.

Science meant looking -- a special kind of looking. Looking especially hard at the things you didn't understand. Looking at the stars, say, and not fearing them, not worshiping them, just asking questions, finding the question that would unlock the door to the next question and the question beyond that.

“I’ve said I understand. Stop fighting after you have won.”

7alienist7yJust because you say you understand (or even think you understand) doesn't mean you do [http://lesswrong.com/lw/ki/double_illusion_of_transparency/].

This type of man who is devoted to the study of wisdom is always most unlucky in everything, and particularly when it comes to procreating children; I imagine this is because Nature wants to ensure that the evils of wisdom shall not spread further throughout mankind.

Erasmus, The Praise of Folly

0Weedlayer7yWhile the quote is anti-rationality, it IS satirical, so I suppose it's fine.

"Applause, n. The echo of a platitude."

--Ambrose Bierce, The Cynic's Word Book

I must respect you before your insults matter to me.

Brandon_Nish Concerning Cyberbullying

Sadly, the insults of those we do not respect often matter, because of what they imply about that person's future conduct, and because of their effects on third parties.

So for example if a bully starts insulting you, this may matter, both because this might indicate he is about to attack you, and because it may cause other people to turn against you. To give a non-cyber-bullying example, the insults of Idi Amin against Indians residing in Uganda surely mattered to them, even though they did not respect him.

This seems inapt as a generalization about human psychology.

In one psychology experiment which a professor of mine told me about, test subjects were made to play a virtual game of catch with two other players, where every player was represented to each other player only as a nondescript computer avatar, the only input any player could give was which of the other two players to toss the "ball" to, and nobody had any identifying information about anyone else involved. Unbeknownst to the test subjects, the other two players were confederates of the experimenter, and their role was to gradually start excluding the test subject, eventually starting to toss the ball almost exclusively to each other, and almost never to the test subject.

Most test subjects found this highly emotionally taxing, to the point that such experiments will no longer be approved by the Institutional Review Board.

In addition to offering a hint of just how much ethical testing standards can hamstring psych research, it also suggests that our instinctive reactions to ostracization do not really demand identifying information on the perpetrators in order to come into play.

Another important factor that influences attraction is similarity… elementary school students prefer other children who perform about as well as they do in academics, sports, and music, and best friends in high school tend to resemble each other in age, race, year in school, and grades. Attributes such as race, ethnic origin, social and educational level, family background, income, and religion do affect attraction in general and marital choice in particular. Also relevant are behavioral patterns such as the degree of gregariousness and drinking and smoki

0Fluttershy7yMy interpretation: in order to have more awesome social interactions, try to seek out both friends and mates who are similar to you along most axes.
1Lumifer7yI don't think that when searching for friends and mates you're looking for a mirror. In an ideal partner there is a balance between the degree to which s/he is similar to you and the degree to which s/he is different (in particular, complementary: strong where you are weak and vice versa).

9FeepingCreature7yNote to Scott: a problem only counts as solved when it's actually gone.

a problem only counts as solved when it's actually gone.

And there are a surprising number of problems that disappear once you have clarity, i.e., they are no longer a problem, even if you haven't done anything yet. They become, at most, minor goals or subgoals, or cease to be cognifively relevant because the actual action needed -- if indeed there is any -- can be done on autopilot.

IOW, a huge number of "problems" are merely situations mistakenly labeled as problems, or where the entire substance of the problem is actually internal to the person experiencing a problem. For example, the "problem" of "I don't know where to go for lunch around here" ceases to be a problem once you've achieved "clarity".

Or to put it another way, "problems" tend to exist in the map more than the territory, and Adams' quote is commenting on how it's always surprising how many of one's problems reside in one's map, rather than the territory. (Because we are biased towards assuming our problems come from the territory; evolutionarily speaking, that's where they used to mostly come from.)

4FeepingCreature7yYeah but it's also easy to falsely label a genuine problem as "practically already solved". The proof is in the pudding. --Two Cult Koans [http://lesswrong.com/lw/m4/two_cult_koans/] Conversely, to show the worth of clarity you actually have to go drive some nails with it.
5pjeby7yYeah... but then that's your second problem. ;-) And that problem exists only in the map, and can be resolved by getting clarity. ;-)
3FeepingCreature7yHaha. True!

Quote from the comedian Frankie Boyle in his new blog post, about people deciding whether they're offended by his jokes:

Also, a lot of people would form an opinion about the joke without having heard it. It's a feature of late capitalism that we get a lot of information thrown at us, and we have to make snap decisions and form strong opinions without really knowing anything. Sure, if our football club buys a new centre half we might do a bit of research. But often we're just being asked if we should bomb Syria or not, and we're busy, and we just have to say fuck it, yeah, my mate Gavin's in the army, so yeah.

I don’t think you can reason people out of positions they didn’t reason themselves into.

Ben Goldacre

3RichardKennaway7yThis is much older than Ben Goldacre. The earliest appearance known to wikiquote [http://en.wikiquote.org/wiki/Jonathan_Swift] is in 1851, in Scientific American . The origin is unknown. It also sounds like Deep Wisdom [http://lesswrong.com/lw/k8/how_to_seem_and_be_deep/]. Let's try a few variations: Once a man's reasoned himself into something, the Devil himself won't reason him out of it. -- this might be plausibly attributed to Thomas Edison. No faith can long survive the light of thought, Which as the salt sea eats away the iron: However stoutly it may seem to stand It yields to sleepless rust and falls apart. When Epicurus "Atoms!" spoke, that light Once kindled ever burned, nor all the priests That spark could e'er extinguish from men's souls Wherein it worked to split the true from false And though it take a thousand years, yet still As iron yields to rust, and stone to frost Inexorable reason knows no sleep. That Church most catholic that holds itself To be the true custodian of the faith: 'Tis but fire-hardened wood, not ageless steel, Which seems at first to gain access of strength From that which would destroy it, but i' the end Must split and crumble into smoking ash. Like to the basilisk gaze is reason's light That scours away the shadows of false night. -- some suitable Victorian figure might be found to ascribe this doggerel to.
5Epictetus7yFound the following in Jonathan Swift's Letter to a Young Clergyman:
0gjm7ySo now RichardKennaway's comment says that the earliest appearance known to Wikiquote is from 1851 ... but it links to Wikiquote's page about Jonathan Swift, with that same quotation. Richard, did you half-edit your comment?
0RichardKennaway7yNo, Google led me to a version of the quote in the section of unverified Swift quotes. I didn't notice that the same thought with slightly different wording appears earlier with a verifiable attribution.
2gjm7yOh yes. How strange. I've tweaked the WQ page to make this less likely to recur.

He who wants to know too much knows in the end nothing, and he who conversely believes that some things do not concern him, often victimizes himself, when, for example, the philosopher believes that history is dispensable to him.

-Immanuel Kant, Logic

4Epictetus7yWhile we're on the subject, here's another: -Seneca, Letter 88

Bean came up with his plan (the Third Invasion) because he thought there was no ansible, so the invasion fleet would hit the formics just when they found out they had lost the Second Invasion. When he found out there was an ansible, if he'd had the slightest sense in his head, he should have realised that the formics therefore knew they lost the moment it happened, seventy years ago, and thus could have launched their own fleet just as long ago.

And even when "truth" can be clearly defined, it is a concept to which natural selection is indifferent.

-Robert Wright, The Moral Animal, p. 272

4Lumifer7yThis seems to be just wrong. If your map significantly doesn't match the territory, natural selection is likely to be brutal to you.
2Torello7yMaybe I should have included the whole paragraph: "And even when "truth" can be clearly defined, it is a concept to which natural selection is indifferent. To be sure, if an accurate portrayal of reality, to oneself or to others can help spread one's genes, then accuracy of perception or communication may evolve. And often this will be the case (when, say, you remember where food is stored, and share the data with offspring or siblings). But when accurate reporting and genetic interest do thus intersect, that's just a happy coincidence. Truth and honesty are never favored by natural selection in and of themselves. Natural selection neither "prefers" honesty nor "prefers" dishonesty. It just doesn't care." He's talking about the "maps" that humans/animals may carry in their brains. These maps don't need to match the territory to be adaptive (I think your criticism of the quote hinges on how you would define "significantly"). But there's quite a bit of space where a "bad map" does not prevent adaptive behavior. For example, some non-venomous snakes "copied" the color patterns of venomous snakes. It's still adaptive for animals to avoid all snakes with this coloring (just to be safe) without needing to know the truth about which snake is dangerous and which isn't. And natural selection is "rewarding" the non-venomous snake for lying about how dangerous it is.
3dspeyer7yThis seems to be conflating possessing truth and sharing truth. The former is almost always valuable. The latter is an interesting bit of game theory, that can go either way. As it has been said, truth may be spoken as events dictate, but should be heard on every occasion.
1Lumifer7yPartially that, but also partially about the direction of the gradient. First, maps never match the territory perfectly precisely, they are always simplified models. In that sense, of course, a map not "matching" the territory is not a obstacle to surviving and prospering. However I would claim that the greater the mismatch between the map and the territory, the greater disadvantage in the natural selection game does the creature accrue. If, magically, you get a choice between getting a more accurate map or a less accurate map, you should always choose the more accurate map. That is not true -- you set up the question wrong. There are three maps involved: map 1 does not recognize venomous snakes at all; map 2 confuses venomous and mimicry-using snakes; and map 3 successfully distinguishes between venomous snakes and mimicry-using ones. Map 3 matches the territory better than map 2 which matches the territory better than map 1. The natural selection would give advantage to an animal with map 3 over the one with map 2, and the one with map 2 over the one with map 1.
0Torello7yI think that point he's trying to make is that natural selection doesn't magically get a choice between maps. In general, a more accurate map will only become available to the mind of some creature if it happens to be adaptive for genes in a particular population in a particular environment. Think of all the creatures with really bad maps. In terms of reproduction, they are doing just fine. For some species, their relative reproductive success can be improved with more accurate maps, but that's a means to the end of reproductive success, There are many ways to "make a living" in evolutionary terms, and having a mind with accurate maps is only one of them. Think of all the creatures who don't have "maps" as humans do. They are still being acted upon by natural selection.
027chaos7yThe idea that it is just "a happy coincidence" makes me think Lumifer's criticism still applies.
0fortyeridania7yThis additional context does help; thanks. Yes, this could be adaptive, but not costless. An animal that avoids all snakes that look venomous misses out on some opportunities (e.g., foraging for food in a tree occupied by a harmless but dangerous-seeming snake). The opportunity cost, in reproductive terms, might be negligible, or it might matter, depending on the specifics. (Here I'm agreeing with you when you point to the importance of the term "significantly.") Because the truth, even in small matters like snake coloration, can make a difference, the original quotation is an overstatement.
0Torello7yAll natural selection "cares about" is genes copied. Claws, peacock tail feathers, and "maps" can all "make a difference," but natural selection only acts on the results (genes copied); natural selection itself doesn't favor any particular kind of adaptation, that's why I think the original quote is not an overstatement.
0hairyfigment7yAs a general statement the quote seems absurd (except in the sense that natural selection has no mind and is thus indifferent to everything). But note that our ancestors' beliefs interacted with evolution by way of predictions (conscious or unconscious) and not by truth directly. Our normative 'beliefs' may have had reproductive value in other ways, but this need have nothing to do with moral truth as defined by those same norms.
1Lumifer7yI don't understand what this means. Is this quote talking about morality and moral "truth"? That's not how I read it -- if it does, it needs more context.
-1hairyfigment7yEvolution determines gene survival by (to use a hypothetical example) whether or not you can throw a spear, rather than whether or not you have an accurate picture of the the underlying physics. Beats me, I just read the title underneath.
0ravenlewis7yyes, i would like to agree with you sir :)
0Torello7yHe's using "indifferent" metaphorically. He would completely agree that natural selection has no mind. What he means is that natural selection operates on differential rates of reproduction of genes, not on the accuracy/truth of the beliefs that the mind of an individual holds.
-1Torello7yAnother way to think about his idea: Natural selection is equally brutal to all life. Moss and ants have horrible maps, but they are still successful in terms of natural selection.
2Lumifer7yThat's not self-evident to me. They certainly have very limited maps, but I don't know if these limited maps are bad.
0Torello7yI agree that "limited" is a better word than "horrible". What I meant by "horrible" is that, relative to human maps, ant maps are extremely limited; they do not represent "truth" or reality as well to the same scope or accuracy of human maps. I think the point is that even though ant maps are limited, they can still be adaptive. Natural selection is indifferent to the scope/accuracy of a map in and of itself.
1Wes_W7yCritically, the areas in which ant maps are limited are the areas in which natural selection doesn't kill them for it. Colonies that think food is in places where food isn't starve to death.
1Torello7yYes, you've hit on the main point. Survival (and later on, reproductive value) is what matters. The fact that the maps help them survive is what matters. The existence of the map or its accuracy matters only matters in so far as it contributes to reproductive success. Natural selection doesn't "reward" them for having an accurate map, only a map that helps they live and reproduce.
0Wes_W7yYes...? And one of the key traits of a useful map is accuracy. I mean, yes, clearly natural selection doesn't value truth for its own sake. It certainly does favor truth for instrumental reasons. I'm uncomfortable phrasing this as "indifferent to truth" as the original quote did. But perhaps we're talking past each other, here.

If a person doesn’t believe climate change is real, despite all the evidence to the contrary, is that a case of a dumb human or a science that has not earned credibility? We humans operate on pattern recognition. The pattern science serves up, thanks to its winged monkeys in the media, is something like this:

Step One: We are totally sure the answer is X.

7Vaniver7yMy personal experience is that I've mostly seen two main camps of climate skepticism, both of which seem to map to contrarian [http://lesswrong.com/lw/2pv/intellectual_hipsters_and_metacontrarianism/] sophistication levels. I don't see many people who are operating at level 2 and climate skeptics. The first is the 'uneducated' critique, that nature is simply too big and variable for man to impact the climate, be sure he's impacting the climate, or have a desired climate reference level. This seems to mostly be out of touch with the data / scientific reasoning in general, but does fit into Adams's claim; one of the reasons why someone might disbelieve claims that we're sure about the causality and predictions is an overall poor track record of science. In this particular field, for example, some predictions of global cooling were made before, and people who value consistency more than correctness are upset by that. (It's worth pointing out that many people do give the argument "you're able to predict what the climate will look like in 80 years but you aren't able to predict what the weather will look like in 8 days?" despite the inherent difference between climate and weather, but that's mostly unrelated to Adams's point.) The second is the 'meta-contrarian' critique, that pokes at the incentives of climate science, the difficulties of modeling, and the desirability of change. As an exercise in scientific number-crunching, climate predictions are very difficult and in a class of models where many tunable parameters can be adjusted to get highly variable results. Most of our understanding of how the climate will behave depends on the underlying feedback loops, and it seems that positive feedback loops (i.e. the temperature increases, which changes things so that temperatures continue to increase) are more publicized than negative feedback loops (i.e. the temperature increases, which changes things so that temperatures stop increasing). There's also evidence that th

0ChristianKl7yThere the xkcd [http://xkcd.com/1074/] comic asking regarding the moon landing: "If NASA were willing to fake great accomplishments, they'd have a second one by now." It's mean, but given the fake NASA discovery that "expands the definition of life" it's funny. At a time where jokes like that can be made, there's really question where the trust is supposed to come from.
5JoshuaZ7yDo you mean the reports of life able to survive in high arsenic environments? In that context it may be important to note that that was poorly done science not deliberate fakery. It is pretty difficult to fake landing on the Moon out of sheer incompetence.
0ChristianKl7yYes, but incompetence still doesn't encourage general trust in science and NASA should have known better than to announce the bacteria that supposedly live in high arsenic enviroments as a discovery that "expands the definition of life" at a big press conference.
2Kenny7yI can easily understand how someone could consider everything NASA (or technologists generally) claims to do as being faked. Everything they claim to do is really hard to verify for almost anyone. And, a lot of it might actually be easier to pull off by faking it – CGI is pretty impressive nowadays and it's not that hard to believe that a lot of images and even video are manipulated or even generated from whole cloth. If you had to verify, personally, that the ESA actually controlled a spacecraft that orbited a comet, etc., how would you do it? Myself, I accept that I'm really trusting a network of people and that I can't practically verify almost anything I'm told.
8Nornagest7yGood question. Intercepting the data stream sent back from the spacecraft would probably be possible (direct imaging at that range isn't in the cards), but it would take some rather sensitive equipment. It might be possible to find amateur astronomers who tracked it during its launch or during its flybys of Earth in 2005, 2007, and 2009, though, and derive a trajectory from that; it's not "personal", but if you don't trust that kind of data, you'd be getting far into conspiracy-theory territory. That'd only get you so far, though. Rosetta's flight plan was pretty complicated and included both several gravity-assist flybys and maneuvers under its own power, so if you doubt ESA's ability to do anything other than get mass near the comet, that'd be tricky to verify. ETA: Googled "amateur spacecraft tracking" and found a response to almost precisely this question [http://www.planetary.org/blogs/emily-lakdawalla/2008/1757.html]. Turns out there are a few amateur groups with the resources to find the carrier signals from deep-space probes. They even have a Yahoo group [https://groups.yahoo.com/neo/groups/amateur-DSN/info].
0Kenny7yGreat response. You're not fully resolving the potential skepticism I identified, but that's impossible anyways. What should be ultimately convincing is that good theories generate good predictions, and you should expect good theories to be connected to other good theories. Unfortunately, I think a lot of people are firmly in "conspiracy-theory territory" already and aren't consistently testing their beliefs. I can sympathize because I know I spend a lot of time generating and trusting weak theories about, e.g. other people's motivations, my likely performance on a particular project.
0ChristianKl7yIn 2010 NASA hold a press conference that they made a discovery that supposedly expands the definition of life [http://science.nasa.gov/science-news/science-at-nasa/2010/02dec_monolake/]. Today the consensus among scientists seems to be that the finding is bullshit. While incompetence is likely the better explanation than malice, it's still a fake. The point is that the network you are trusting was likely wrong about a big discovery that NASA claimed to have made in this decade. Maybe even the biggest claimed discovery of NASA in this decade.
7gjm7yI have no idea exactly what network Kenny trusts how much, but just about everything I read about NASA's alleged discovery was really skeptical about it and said "yeah, this would be amazingly cool if it were true, but don't hold your breath until it's been confirmed by more careful investigation". And, lo, it was not confirmed by more careful investigation, and now everyone thinks it was probably bullshit. Much the same story for superluminal neutrinos (more so than the arsenic-using life) and CMB polarization due to inflation (less so than the arsenic-using life).
6ChristianKl7yIn the case of the neutrinos the announcement there was much more skepticism on the part of the people who made the discovery.
3gjm7yYup, but I don't think that's relevant to how reliable the people Kenny trusts to tell him about scientific research are.
5elharo7yIn the case of superluminal neutrinos, pretty much nobody including the people who made the announcement believed it; and the real announcement was more along the lines of "we've got some problematic data here; and we can't find our mistake. Does anyone see what we've done wrong?"
3Kenny7yGood point. But my trusting a network of people, or really many (overlapping) networks of people, doesn't mean that I trust every specific claim or theory or piece of information. It just means that I've learned that they're overall trustworthy, or trustworthy to a specific (perhaps even quantifiable) extent, or maybe only trustworthy for certain kinds of claims or theories or information.

We can't go back, Mat. The Wheel has turned, for better or worse. And it will keep on turning, as lights die and forests dim, storms call and skies break. Turn it will. The wheel is not hope, and the Wheel does not care, the Wheel simply is. But so long as it turns, folk may hope, folk may care. For with light that fades, another will eventually grow, and each storm that rages must eventually die. Thom Merrilin, The Gathering Storm by Robert Jordan and Brandon Sanderson

Indecision and delays are the parents of failure.

George Canning, source.

Failure is the child of a... very extended family, including impulsiveness and hot-headedness.

6Salemicus7yAgreed. Very often the opposite of these quotations could also be a rationality quote. No such quote is ever going to cover the full spectrum, and they will always be from the speaker's experience and reflecting his personality. In context, then, it is worth pointing out that Canning was a politician who achieved perhaps his greatest success in wartime, and who is otherwise best known for running a highly active and aggressive (and successful) foreign policy, largely independently of the rest of the government. He's also notorious for having a duel against another Cabinet minister, which hugely damaged his career, so "impulsiveness and hot-headedness" is a yes. As Muir wrote [https://books.google.co.uk/books?id=1eQBrz9o17UC&pg=PA59&lpg=PA59&dq=%22he+was+a+passionate,+active,+committed+man+who+poured+his+energy+into+whatever+he+undertook.%22&source=bl&ots=5jCbfcw8Sp&sig=vfUoOgPqvjUvDs0bISyKAM7knbo&hl=en&sa=X&ei=U6_QVMzmJ5TjatLtgMAN&ved=0CCcQ6AEwAQ#v=onepage&q=%22he%20was%20a%20passionate%2C%20active%2C%20committed%20man%20who%20poured%20his%20energy%20into%20whatever%20he%20undertook.%22&f=false] : Emphasis mine.

For example: most men have inner conflicts of values; these conflicts, in most lives, take the form of small irrationalities, petty inconsistencies, mean little evasions, shabby little acts of cowardice, with no crucial moments of choice, no vital issues or great, decisive battles--and they add up to the stagnant, wasted life of a man who has betrayed all his values by the method of a leaking faucet.

5emr7y-- Emerson, Self-Reliance Perhaps these are two prescriptions for two different patients: The fox and the hedgehog!
5elharo7yAbsent context, I notice I'm confused about which sense of the word "values" she's using here. Perhaps someone can elucidate? In particular is she talking about moral/ethical type values or is she using it in a broader sense that we might think of as goals?
2hwold7yCan’t tell for the Romantic Manifesto, but in Atlas Shrugged, Ayn Rand uses the word “value” as a synonym of “rule of conduct”. For example, she argue that “rational evaluation” is a correct value for man in the same way that “flying” is a correct value for birds. She calls her philosophy objectivism because the thinks that correct values, which means rules of conduct that leads to environmental fitness (in her words says : “survival”), are objective.
0Kenny7yFunny enough, I'm confused by your distinction between moral or ethical values and goals – aren't those really the same? Ayn Rand held that some preferences were rational or more rational than others.
2[anonymous]7yThe first sentence read like sound logic to me (personally, not speaking for other guys), but I couldn't really figure what the hell she wants from my life from all the rest. I could explain, but that would be A. a spoiler and B. a potential (and equally idiotic, aka "reach a conclusion already idiots) type of) flamewar that shouldn't be here.
1Vaniver7yAs far as I can tell, that quote is one sentence, so I'm not sure how you're dividing it up.
0[anonymous]7y"For example: most men have inner conflicts of values;" This part. It's an issue I can solve quite easily, but at the same time it feels like the bar is being set lower, rather than higher, and that's what irks me.
0Vaniver7yThe quote is exhibiting a thing not to do, so that doesn't seem that surprising to me. I'd restate the quote as something like "resolve your inner conflicts, even if that requires dramatic effort, rather than letting them fester."

“What about honor and ethics?” “We’ve got honor in us, but it’s our own code...not the make-believe rules some frightened little man wrote for the rest of the frightened little men. Every man’s got his own honor and ethics, and so long as he sticks to ’em, who’s anybody else to point the finger? You may not like his ethics, but you've no right to call him unethical.”

-Alfred Bester, in The Demolished Man chapter 6 p 84, according to wikiquote

8alienist7yIn that case who is Alfred Bester to tell me who I can or can't call "unethical"?
2wadavis7yI like how this touches on respecting the agency of others. The idea that: I do not like how you operate, but I will respect that you are a thinking person, and for that reason alone, deserving of respect.
