(Since there didn't seem to be one for this month, and I just ran across a nice quote.)

A monthly thread for posting any interesting rationality-related quotes you've seen recently on the Internet, or had stored in your quotesfile for ages.

Please post all quotes separately (so that they can be voted up (or down) separately) unless they are strongly related/ordered.
Do not quote yourself.
Do not quote comments/posts on LW/OB - if we do this, there should be a separate thread for it.

"There is nothing so useless as doing efficiently that which should not be done at all." - Peter Drucker

4Nominull13y

Surely it's at least as useless to do it inefficiently?

8conchis13y

Depends what "it" is. If the alternatives are killing 10 people efficiently at a cost of $100 a head vs. killing ten people inefficiently at a cost of $1000 a head, then killing them inefficiently is worse: I've not only killed 10 people, I've wasted $9000 worth of resources that could have been used to do something actually useful. But if I've been given a $10,000 killing budget, then it's clearly better for the world if I spend this inefficiently and only manage to kill 10 people rather than 100.

-1tim13y

this seems to convolute the example with personal moralities that have no bearing on the actual, objective "task" and how efficiently or inefficiently it is accomplished. if the goal is to kill people, your moral qualms don't make it "better" to kill less. you are still performing poorly relative to the task. this does highlight a problem with the original quote. "useless" is rather ambiguous as the reader has to decide whether to tie "use" to the utility of the task relative to what it is trying to accomplish versus the reader's personal goals. the same applies to the equally ambiguous word, "should."

5Vladimir_Nesov13y

Doing it efficiently turns you into a dangerous paperclip monster [http://wiki.lesswrong.com/wiki/Paperclip_maximizer], while doing it inefficiently makes you a mere harmless rock.

I guess it implies the extra cost of optimizing the useless task. Mostly agreed, though.

A competitive game, to me, is a debate. You argue your points with your opponent, and he argues his. “I think this series of moves is optimal,” you say, and he retorts, “Not when you take this into account.”

Debates in real life are highly subjective, but in games we can be absolutely sure who the winner is.

-- David Sirlin, Playing to Win

0JGWeissman13y

I like this, but beware the converse. Debates should not be competitive games. The goal is not to steer a path through the game tree that causes your opponent to seem a fool, but to resolve disagreement by the discussion of the actual reasons you have for your position. Edit: After I started reading the linked source, I find my position really contrasts with Sirlin's:

[-]Eliezer Yudkowsky13y 8

That, I think, is part of the nature of beliefs about justice—they are absolute, bright edged, in a way in which preferences are not. The point is summed up in the Latin phrase Fiat justicia, ruat coelum—let justice be done though the sky falls. Those whose bumper stickers read "If you want peace, work for justice" simply take it for granted that there is no question what is just; if you want to find out, just ask them. The problem with the world as they see it is merely that other people are insufficiently virtuous to act accordingly.

People normally read only their own horoscope in the newspaper. If they forced themselves to read the other 11 they'd be far less impressed with the accuracy of their own.

-- Richard Dawkins, "Unweaving the Rainbow"

6thomblake13y

I can't find a reference, but I'm pretty sure this is actually false. Someone who reads a horoscope with his 'sign' attached tends to think the horoscope applied particularly well to himself (even amongst skeptics). Obviously, removing the 'signs' makes them indistinguishable.

3JamesAndrix13y

Obviously, removing the 'signs' makes them indistinguishable. I wonder if this is true. There is a personality attached to 'Aquarian' even within the generalism of horoscopes. If I've been reading a horoscope for many years that encourages me to act like an Aquarian, and think like and Aquarian, Then perhaps I just won't identify with the advice that the same astrologer would give to 'Scorpio'.

[-]Jack12y 10

Relevant anecdotal evidence: I have a cousin who was really in to astrology a few years ago: so obviously my sister and I insisted she partake in an experiment. We had her do three specific readings (not just with signs but with the mercury rising nonsense for which she needed exact birth-dates and birth locations): for me, my sister and my brother who wasn't there. She read them to us without indicating who they belonged to and we tried to see if we could tell which ones referred to us. The second one she read was just shocking to hear. It described me perfectly. I was in awe for about 10 minutes until the experiment finished and I learned that the reading that described me perfectly belonged to my sister.

5fburnaby12y

My girlfriend have been casually collecting data on this over the past 2 years. We occasionally end up in social situations with people who are flaky enough to take this stuff seriously. They'll usually -- after about 15 minutes of conversation -- make note of our 'auras' or personalities, and then guess a sign for each of us. We encourage them to try. Of the eight guesses we've had about our signs so far, none have been correct within 2 tries. I hope a few more years of this (and maybe some more data from less flaky friends) will offer enough data points to see if there's any bias, or if the odds of a good initial guess are uniform.

2Technologos13y

I think the point is that people attach a feeling of truth to their own horoscope, without considering whether other horoscopes could feel similarly true.

...look at 9/11 tower destruction theories. They want to believe something other than the planes caused the buildings to collapse. OK fine, let them bark up that tree if they want, but why must they leap to bizarre stories about government agents and secret operations? None of that is necessitated by the idea that another mechanism was fully or partially responsible. Why don't they suspect that Al-Quaeda planted a bomb in the basement in order to hasten the building's collapse, as a secondary part of their operation? Why leap to the US government as the c

8dclayh13y

That quote seems silly. If there were hidden elements to 9/11 (or JFK, or anything) obvious enough for lone nuts to find, then it's reasonable to assume the government investigation would have found them also. Given that the government investigation didn't say anything about it, then, it's reasonable to assume it's because they have something to hide.

3SoullessAutomaton13y

Also, there's the obvious, cynical "cui bono?" point. The government is one of the few entities that could reasonably be said to have benefitted from the attacks (expanded power, pretense for war, &c.), so if you start with the assumption that the "official story" is wrong the government would be the next most plausible culprit. The argument used is much more applicable to creationist arguments of the form "evolution has this flaw, ergo god exists".

[-]dclayh13y 10

I heard an interview with the guys who do South Park that for their 9/11 conspiracy episode they were considering making the real culprits the American flag manufacturers, because they clearly benefited the most.

9SoullessAutomaton13y

So... China?

2jimrandomh13y

Which government? Almost all the major world powers have spy agencies that could've pulled it off. Russia would do it because of ex-Soviets holding a grudge. China would do it to strengthen their relative economic power. Israel would do it to ensure the US would continue backing their military. Most of the countries in the middle east, and half the countries in Latin America have grievances against us. Lots of people acted strangely that day, but trustworthy information is hard to come by. More than anything else, 9/11 reminds me of the story of Alexander Litvinenko, which was in the news in 2006: Spy poisoned, accuses spy agency, spy agency denies it and accuses different spy agency, radioactive trail painted to someone's door, and you might as well roll a die to decide who to accuse, because very skilled agents have already destroyed the evidence.

Mr. President, it is natural to man to indulge in the illusions of hope. We are apt to shut our eyes against a painful truth, and listen to the song of that siren till she transforms us into beasts. Is this the part of wise men, engaged in a great and arduous struggle for liberty? Are we disposed to be of the number of those who, having eyes, see not, and, having ears, hear not, the things which so nearly concern their temporal salvation? For my part, whatever anguish of spirit it may cost, I am willing to know the whole truth; to know the worst, and to provide for it.

Most of us, I suspect, would rather believe that the devil is running things than that no one is in charge, that our lives, our loves, World Series victories, hang on the whims of fate and chains of coincidences, on God throwing dice, as Einstein once referred to quantum randomness. I've had my moments of looking back with a kind of vertigo realizing how contingent on chance my life has been, how if I'd gotten to the art gallery earlier or later or if the friend I was supposed to have dinner with had showed up, I might not have met my wife that night, and our daughter would still be in an orphanage in Kazakhstan.

All advances of scientific understanding, at every level, begin with a speculative adventure, an imaginative preconception of what might be true — a preconception that always, and necessarily, goes a little way (sometimes a long way) beyond anything which we have logical or factual authority to believe in. It is the invention of a possible world, or of a tiny fraction of that world. The conjecture is then exposed to criticism to find out whether or not that imagined world is anything like the real one.

My interpretation: "As a woman, you are stuck with not being allowed to speak what you think, but there is a workaround for this."

2zaph13y

It's a line from a play called Love for Love. The quote is voiced by a character; so the presentation here lacks that context. The play was satirical, and I wouldn't take the quote at face value. I think Congreve was voicing what had become the standard social games of his time - say like Barney on How I Met Your Mother.

[-]NihilCredo13y 1

But now I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth.

Umberto Eco, "Foucault's Pendulum"

4HughRistik13y

This is actually an anti-rationality quote. Enigmas of the world are not harmless. Just try fighting "harmless enigmas" like diseases before germ theory. The mysteries of the world are not made terrible by our attempts to interpret them as though it had an underlying truth. I interpret this quote to suggest that mysteries are harmless, and that trying to understand the world is what is harmful. The vast majority of the time, this view is backwards; it is falsified by the history of science. I really hope this isn't what the quote means in context, because otherwise, it is mystery mongering [http://lesswrong.com/lw/fo/religion_mystery_and_warm_soft_fuzzies/], and I can't even begin to fathom what is wrong [http://lesswrong.com/lw/fy/what_is_wrong_with_our_thoughts/] with the thought process that led to it. What we don't know can hurt us. Attempting to understand the world based on an underlying structure is at least instrumentally rational, and it might even be true, also. I'm curious about the context of the quote, and what NihilCredo thinks it has to do with rationality.

5gwern13y

Larry Niven, "Flatlander" (1967)

3thomblake13y

In my view, Eco wasn't referring to things in the world like diseases, but rather the world itself. Trying to answer questions like "what is the meaning of life" or "why does anything exist rather than not exist" can drive you mad, and it's a pointless exercise. The takeaway: accept that life has no 'meaning' beyond what we give it, and move on.

1HughRistik13y

Diseases are a part of the world. My point is that empirical mysteries are not harmless. I agree with your view. Empirical mysteries are bad. Yet certain non-empirical mysteries such as questions of metaphysical meaning, or value judgment, are better left off as mysteries. Unlike empirical questions, there is no right answer. As many philosophers have argued, a lot of human suffering is based on assigning inappropriate meaning to things. Indeed, cognitive behavioral therapy, and self-help such as The Work [http://en.wikipedia.org/wiki/Byron_Katie] of Byron Katie are based on destroying or suspending these meanings that people assign. I hope this is what Eco means in context. But it's not what is literally said in this quote: the phrase "the whole world" sounds like it is also referring to empirical phenomena.

5Cyan13y

The novel is a satire on conspiracy theories. The entire book can be read as a polemic against the mind projection fallacy and confirmation bias.

Would it help to note that the book was something of a reductio of conspiracy theories?

Oh, so is it one of Eco's characters asserting this view? That would make more sense.

It is the narrator's final despair of rationality. He and his colleagues in a publishing house, having read many conspiracy theories, start inventing their own as an intellectual game. But it gets taken up by real conspiracy theorists; hijinks ensue.

"...any inward-oriented and continued effort to improve the match-up of concept with observed reality will only increase the degree of mismatch...Put another way, we can expect unexplained and disturbing ambiguities, uncertainties, anomalies, or apparent inconsistencies to emerge more and more often. Furthermore, unless some kind of relief is available, we can expect confusion to increase until disorder approaches chaos— death.

Fortunately, there is a way out."

~ John Boyd, Destruction and Creation

1RichardKennaway13y

This looks not like rationality, but like one of David Stove's examples [http://lesswrong.com/lw/fy/what_is_wrong_with_our_thoughts/] of thought gone wrong. And like his examples, the context is just more of the same. Can you explain what you see in Boyd's words? ETA: I've since googled to see who John Boyd [http://en.wikipedia.org/wiki/John_Boyd_(military_strategist\]) was, and he was a notable military strategist credited with fundamental improvements to fighter aircraft design. That tweaked my interest up enough to read some more of his work, but I am still unable to see anything in it.

5HughRistik13y

I agree. Many of the sentences in this essay have something horribly wrong with the thought process behind them, but I can't even begin to describe what it is. There is a similar problem with the Umberto Eco quote [http://lesswrong.com/lw/g1/rationality_quotes_may_2009/cxw] below. The above quote begins with this: I am pretty sure that Boyd is badly mangling Heisenberg, the Second Law of Thermodynamics, and Godel's Incompleteness Theorem, or his extrapolations are way off. In fact, someone mentioning Heisenberg's Uncertainty Principle, the Second Law of Thermodynamics, and Godel's Incompleteness Theorem all in one place, triggers my Bayesian epistemic spam filter. Some people's minds seem to be infected with a strange solipsistic and skeptical epistemic disease where they think that trying to understand reality is futile, and will lead to either increasing mismatch of the map to the territory (in the case of this quote), or some other "terrible" results (in the case of the Eco quote). How the hell do people come with ideas like these??

2thomblake13y

That's actually a position of reasonable people who engage in non-greedy reductionism, mostly replying to greedy reductionists (to use Dennett's terminology). To give an example, suppose you're trying to get better at playing chess on a chess program running on a computer. Further suppose that the computer you're using is a Turing machine being implemented in Conway's Game of Life. Does understanding the behavior of a turing machine, or gliders and spaceships, or the basic rules of the Game of Life, increase your understanding of how to get better at chess? Will focusing on such things make you better or worse at playing chess? That said, I agree with you about the above quote.

0HughRistik13y

Trying to understand reality is futile is a narrow and trivial sense: the map will never completely match the territory. That's not the notion I'm criticizing. In the case of Boyd, when he says "any inward-oriented and continued effort to improve the match-up of concept with observed reality will only increase the degree of mismatch," he seems to imply that the harder we work to create a model of observed reality with our concepts, the worse the match will be. That's a truly weird notion. Maybe his quote goes from being an example of thinking gone horribly wrong, to thinking gone horribly explained, if we try to figure out what he means by "inward-oriented." If we are charitable and creative, perhaps Boyd means something like this: "given a bad theory, additional ad hoc modifications increase the mismatch between the theory and observed reality." Though I don't think that's true either: ad hoc modifications of a bad theory don't "increase" its mismatch with observation. Rather, they stretch the theory until it does match the observations, making the theory more strained. A much better framework for discussing matches of theory with observation than Boyd's 9th grade philosophy paper is Imre Lakatos' work on "progressive" vs. "degenerating" research programs [http://en.wikipedia.org/wiki/Imre_Lakatos#Research_programmes].

1Kakun13y

The key word here is "inward-oriented;" that is, based on internal logic, instead of on new evidence. When previous theories are destroyed by the mismatch with reality, the facts that supported the previous theory are either revealed as untrue, or merged into a newer and more correct theory, that incorporates new evidence and different links between the facts to come to a different, and presumably superior, conclusion. On second though, that was a bad section to quote, although Boyd never really gave any better ones in his essay. I tried to note the way out without throwing on too much of Boyd's pointless terminology in the last sentence ("Fortunately, there is away out.") I clearly failed; my bad.
