During the discussion of Pranknet on Slashdot about a month ago, I saw this comment. It reminded me of our discussions about Newcomb's problem and superrationality.

I also disagree that our society is based on mutual trust. Volumes and volumes of laws backed up by lawyers, police, and jails show otherwise.

That's called selection/observation bias. You're looking at only one side of the coin.
I've lived in countries where there's a lot less trust than here. The notion of returning an opened product to a store and getting a full refund is based on trust (yes, there's a profit incentive, and some people do screw the retailers [and the retailers their customers -- SB], but the system works overall). In some countries I've been to, this would be unfeasible: Almost everyone will try to exploit such a retailer.
When a storm knocks out the electricity and the traffic lights stop working, I've always seen everyone obeying the rules. I doubt it's because they're worried about cops. It's about trust that the other drivers will do likewise. Simply unworkable in other places I've lived in.
I've had neighbors whom I don't know receive UPS/FedEx packages for me. Again, trust. I don't think they'

2John_Maxwell12yPerpetually angry dude makes the opposite case [http://richardkulisz.blogspot.com/2009/01/low-trust-in-crazyland.html]. Never get an argument with that guy, by the way.

2CronoDAS12yYeah, looking over his blog, he never has arguments, only shouting matches. Considering his rampaging contempt for everyone who is not himself, I wonder why he even bothers to publish anything at all.

2taw12yUS is higher than most of non-Northern Europe when it comes to trust. http://www.nationmaster.com/graph/lif_tru_peo-lifestyle-trust-people [http://www.nationmaster.com/graph/lif_tru_peo-lifestyle-trust-people] The first theory is diversity, but trust here doesn't seem to correspond to diversity at all - Norway and Austria are homogenous and on opposite ends. Canada and Belgium are diverse and on opposite ends. As for other theories, socialist countries are also on both top (Scandinavia) and bottom (Austria, France). Catholic countries seem to be lower than Protestant countries, but Ireland is pretty high, and it might just be Scandinavia making this impression. So I'm not really sure what trust correlates much with.

2Douglas_Knight12yWhich countries on that list do you call not socialist? English-speaking ones? Switzerland? Where can we get objective information about whether people are trusting or trust-worthy, rather than what they say? The Japanese claim to be less trusting than Americans, but they are trustworthy with wallets, if not with umbrellas and bicycles. and the angry dude argues that Americans should not trust institutions which is completely different from whether they do trust people, which is the topic of the survey and the slashdot entry.

0taw12yUS, Japan, and Switzerland seem less socialist than Scandinavia, Austria, and France by standard measures, right? Questionnaire is a proxy measure, but it's better proxy than some random blog rant. Here are some obvious things that might reasonably correlate with trust, but don't seem to: * http://en.wikipedia.org/wiki/List_of_countries_by_tax_revenue_as_percentage_of_GDP [http://en.wikipedia.org/wiki/List_of_countries_by_tax_revenue_as_percentage_of_GDP] * http://en.wikipedia.org/wiki/List_of_countries_by_income_equality [http://en.wikipedia.org/wiki/List_of_countries_by_income_equality]

The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.

2dclayh12yA cursory Google search doesn't reveal the date of this quote. Do you know if it was before or after Yeats's version of 1919? (Wikipedia claims that Yeats was inspired by Shelley...)

I would roughly divide philosophies into two categories, "crazy" and "sensible". Of the two, I definitely prefer the former. Sensible philosophies are noted for their sobriety, propriety, rationality, analytic skill and other things. One definite advantage they have is that they are usually quite sensible. Crazy philosophies are characterized by their madness, spontaneity, sense of humor, total freedom from the most basic conventions of thought, amorality, beauty, divinity, naturalness, poesy, absolute honesty, freedom from inhibitions

Lighthouses are more helpful than churches.

-Benjamin Franklin

0sketerpot12yThe real confusion begins when you make lighthouse-churches, and people start defending the religious doctrines by saying that faith-based buildings are the only possible source of warning-lights to sailors, and hey, just look at all that beautifully cylindrical architecture, so it must be a great and necessary thing to believe in [insert wacky stuff here]. Rationalizations for silly things one came to believe as a child are always ugly, because everything gets all jumbled up in people's heads, and they don't want to straighten it out, because that would be a thought crime. [Sorry, was that venting a little? I get so sick of this argument, but I can't bring myself to humor people who say it.]

You won't gain knowledge by drinking ink.

-Arab proverb

2Rain12yMaybe it needs further explanation? Ink being the object with which books are created, and knowledge put down for others to use, you must be careful to avoid using that object directly and believing you have gained knowledge from it. The blog post itself isn't the great insight, nor is the Reddit software it's running on, or the comment system, or the upvoting and downvoting. Insight can only come from the mind, and understanding the words and how they all link together into the idea being presented. The idea isn't in the text; it's an abstraction of the human mind. Perhaps better summarized as, "Don't just read: think."

4Rain12yAlternatively, "Put down the RSS feed and go learn something."

-2John_Maxwell12yI don't see the connection. The point of the original quote is that the medium is independent of the info it carries. You're quote says the opposite: one particular medium (RSS) is incapable of carrying info.

We at the Church of Google believe the search engine Google is the closest humankind has ever come to directly experiencing an actual God (as typically defined). We believe there is much more evidence in favour of Google's divinity than there is for the divinity of other more traditional gods.
We reject supernatural gods on the notion they are not scientifically provable. Thus, Googlists believe Google should rightfully be given the title of "God", as She exhibits a great many of the characteristics traditionally associated with such Deities in a

4SilasBarta12yHeh, it's funny that you first put it in the LW/OB quotes section, because that's actually kind of similar to an out-of-context quote [http://lesswrong.com/lw/13b/dreams_with_damaged_priors/1137] I excerpted from Eliezer Yudkowsky here.

A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines. With consistency, a great soul has simply nothing to do.

-Ralph Waldo Emerson

1anonym12yIf I only had a dollar for every time somebody misquoted that wonderful quote to me as "consistency is the hobgoblin of little minds"...

-1thomblake12yNot a misquote, just slightly out of context. And I'm fairly sure Emerson would apply 'foolish' to most sorts of consistency.

2anonym12yIt omits a crucial part of the quote that results in a completely different meaning. Leaving out an adjective that it is integral to the meaning is different than omitting some minor context.

0thomblake12yThat's why I pointed out that leaving out 'foolish' probably doesn't change Emerson's intent at all. Worrying about consistency at all is what he found troublesome - he counseled against trying to be consistent in general, and I take 'foolish' to be more superlative than anything.

0anonym12yYou may be right that it doesn't change the meaning much, in which case it's still a misquote, but a minor one (such as using a synonym of a word instead of the actual word: correct sense, wrong words). What it definitely is not is "just slightly out of context", since that means the utterance is missing context and as a result appears to mean something other than what was intended, which is precisely what you're arguing has not happened.

0thomblake12yI disagree on both points. It is not a misquote since it is entirely the words Emerson actually wrote, as he wrote them. It is out of context since there are words nearby ("context") that were not included.

1anonym12yI guess we understand the phrase "out of context" differently then and have to disagree. I would never use it for leaving out a single adjective, and haven't heard it used that way. I have only heard it used when entire clauses or sentences are omitted. I note that wikipedia seems to agree with my interpretation.

When the time comes, there is no moment for reasoning. And if you have not done your inquiring beforehand, there is most often shame. Reading books and listening to people's talk are for the purpose of prior resolution.

The word “philosopher” has its origins in the Greek, where its root is a “lover of wisdom.” There is no assurance that a lover of wisdom has any, just as an anglophile is not assured to have an Englishman locked in the basement.

Extraordinary claims require extraordinary evidence -- Carl Sagan

Economic growth occurs whenever people take resources and rearrange them in ways that are more valuable. A useful metaphor for production in an economy comes from the kitchen. To create valuable final products, we mix inexpensive ingredients together according to a recipe. The cooking one can do is limited by the supply of ingredients, and most cooking in the economy produces undesirable side effects. If economic growth could be achieved only by doing more and more of the same kind of cooking, we would eventually run out of raw materials and suffer from un... (read more)

Great thinkers build their edifices with subtle consistency. We do our intellectual forebears an enormous disservice when we dismember their visions and scan their systems in order to extract a few disembodied “gems”—thoughts or claims still accepted as true. These disarticulated pieces then become the entire legacy of our ancestors, and we lose the beauty and coherence of older systems that might enlighten us by their unfamiliarity—and their consequent challenge—in our fallible (and complacent) modern world.

-- Stephen Jay Gould

0RichardKennaway12yDo you have the context for that one? My immediate reaction is to suspect that Gould wants to rehabilitate some discarded old idea, and talks about consistency, beauty and coherence as a way of not talking about evidence and truth. But perhaps I am too suspicious.

0[anonymous]12yI don't have the context for that particular wording, but it's a recurring theme of his essays. He felt that wrong ideas could still be instructive, and he would often write essays explaining ideas that he clearly referred to as incorrect. His point here seems to be that the theory is already wrong, so don't destroy the remaining value by cutting it up to extract the bits you could get from current theory. I don't think you need to worry that he's calling for a return to something you dislike.

Elpinice was skeptical. She likes evidence. That means a well-made argument. For Greeks, the only evidence that matters is words. They are masters of making the fantastic sound plausible.

A single conversation with a wise man is better than ten years of study.

[-]Eliezer Yudkowsky12y 16

That had better be a long conversation, a very wise person, and one damned lost field you were studying for ten years.

1[anonymous]12yThis is a lesswrong quote, but I think it belongs in this discussion because it's remarkably apropos: -- Eliezer Yudkowsky

-1PeterS12yWise in comparison. The other quantifiers are hyperbole. The quote applies insofar as the field being studied is already somewhat mapped and investigated. Programming forums are ultimately more useful than tutorials and textbooks, talking to an author more insightful than reading the 200 page thesis, and having access to a community of intelligent synthetics is much more valuable than having access to a library.

6sketerpot12yFind the right books, and it'll probably be far more rewarding than talking to an author, simply because of the information density and better organization that you can get in written form. An hour of reading Hennessy and Patterson's excellent book on CPU design [http://www.amazon.com/Computer-Architecture-Quantitative-Approach-4th/dp/0123704901/ref=dp_ob_title_bk] will teach you a hell of a lot more than six hours of classes. I speak from recent quantitative experience here, which is where I got those specific numbers. The exceptions to this rule are local: particularly hard-to-understand concepts like the Tomasulo algorithm [http://en.wikipedia.org/wiki/Tomasulo_algorithm] are a lot easier to wrap your head around if you have someone to walk you through them. But for the most part, a well-written textbook can teach you better than a person talking with you. One problem is that most textbooks just aren't written that well. Often they're too concerned with signaling academic status, and they forget to make the book something that people will want to read. Just because an author can go off on a tangent [http://tvtropes.org/pmwiki/pmwiki.php/Main/BigLippedAlligatorMoment] about graph isomorphisms [http://en.wikipedia.org/wiki/Graph_isomorphism] doesn't mean they should. Other times they get bogged down in obscure details up front, killing off people's interest. There are other failure modes [http://www.textbookleague.org/103feyn.htm], too depressing to list here. By the way, I think that one reason why wikis are so easy to learn from is because you can skip past the boring stuff until you need it. This makes reading a wiki more fun, and also leads to tab explosions [http://xkcd.com/214/], keeping you hooked. I figure that this could significantly improve on the traditional textbook model, despite all those nice things I said about it earlier in the post. (In honor of the tab explosion, I've stuck in a bunch of links to pages that might be interesting.)

5Kaj_Sotala12yOnly if he were an exceptionally bad writer. 200 pages contains a lot more information than you can fit into most conversations. Not to mention being more logically structured. Of course, a conversation is more interactive and lets you ask about the things that were left unclear, as well as clear up misunderstandings... but I don't think that anywhere near compensates. What you could argue is that talking to the author is time more efficiently spent, as it gives you a better idea of whether her thesis is worth reading.

-2Nominull12ymost people are exceptionally bad writers

4RolfAndreassen12yHow can that be the case? You apparently have 'exceptions' forming most of the population! More generally, being able to talk to the author after reading the thesis is hugely valuable, because whatever was unclear in the thesis can be cleared up. But talking to the author without reading his work is fairly worthless; you won't know what questions to ask, unless of course you're already knowledgeable in the field.

0rwallace12yBut actually it also applies only insofar as you have already studied the field. Programming forums are great, but we've all seen the guy who shows up to post a tutorial question verbatim and appends "send me the code plz", and we all understand he's just wasting everybody's time. You have to read the textbooks and at least seriously attempt the tutorials yourself before you can ask the right questions on the forum.

1darius12yYou could see that as anthropomorphizing the power of interaction [http://en.wikipedia.org/wiki/Interactive_proof_system].

0SilasBarta12yMeh. Maybe if that wise man is Eliezer Yudkowsky. But then, calling Eliezer Yudkowsky a "wise man" is like calling the Sahara Desert a "litterbox". Or Chuck Norris a "tough guy". ETA: Grr! I can't put underscores in people's names anymore without adding italics!

2dclayh12yIs it perhaps time for another round of Eliezer Yudkowsky Facts [http://lesswrong.com/lw/4g/eliezer_yudkowsky_facts/]?

0thomblake12yJust backslash escape them - type it like this: Eliezer\_Yudkowsky ETA: this is an amusing example of "do as I say, not as I do". What I actually typed looked like this: Eliezer\\\_Yudkowsky

0SilasBarta12yI think you misunderstand the problem. I know I can override the formatting. It's just that if I did so, it would invalidate my claim that I have software that lets me call up forum screen names with hotkeys, and replaces the spaces with underscores in forums that allow spaces in names. In other words, people would know I was needlessly typing out their whole screen name and adding underscores, and it wasn't just some glitchy software.

0kpreid12yOf who is this a quote?

1PeterS12yI believe it's actually a Chinese proverb.

7billswift12yYou need to be careful of supposed Chinese proverbs; I recently found that the Chinese curse "May you live in interesting times" was actually created in the fifties by Eric Frank Russell.

2ChrisHibbert12yIt has to be "may your grandchildren live in interesting times", or the caster of the curse is as cursed as the recipient. sheesh!

1SilasBarta12yMaybe the problem is that you're focusing too much on whether the proverb is authentic Chinese rather than on whether it accurately captures reality?

The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents.

-H.P. Lovecraft

1Eliezer Yudkowsky12yIt could be true, but how would anyone know?

3thomblake12yWell it may be technically false that the human mind has this inability, but on the other hand the human mind has a remarkable ability to avoid correlating many of its contents. "Belief is not closed under implication!"

-3CronoDAS12yConsistency checking is NP-complete... "Compartmentalization" may be a rationalist sin, but you can't learn anything efficiently if you have to keep checking every fact against every other fact.

0thomblake12yThat's a pretty strong claim. Is there a proof? Or did you just mean that consistency checking is in NP?

3RichardKennaway12yIt's worse than that, consistency checking is undecidable. This is implied by Gödel's second incompleteness theorem.

1CronoDAS12yWell, 3-SAT [http://en.wikipedia.org/wiki/Boolean_satisfiability_problem] is NP-complete, anyway. If consistency checking in mere propositional logic is already NP-complete, then it can't be any easier to do consistency checking to real-world arguments that require predicate logic or other, even more complicated systems to express. Godel Escher Bach has a section that talks about this.

In the words of the ancients, one should make his decisions within the space of seven breaths. Lord Takanobu said, "If discrimination is long, it will spoil." Lord Naoshige said, "When matters are done leisurely, seven out of ten will turn out badly. A warrior is a person who does things quickly."
