No, Mr. Shepard, with respect, (that) is not the moral of the story. The moral of the story is that, if you have grounds to believe there is a ferocious predator at large, don't appoint as your sole watchman a twelve-year-old child whom you have resolved to ignore.

  • Mitchell and Webb prosecuting attorney, from the sketch, "The boy who cried wolf"

When I was in law school, I devised my own idiosyncratic solution to the problem of studying a topic I knew nothing about. I'd wander into the library stacks, head to the relevant section, and pluck a book at random. I'd flip to the footnotes, and write down the books that seemed to occur most often. Then I'd pull them off the shelves, read their footnotes, and look at those books. It usually took only 2 or 3 rounds of this exercise before I had a pretty fair idea of who were the leading authorities in the field. After reading 3 or 4 of those books, I usually had at least enough orientation in the subject to understand what the main questions at issue were - and to seek my own answers, always provisional, always subject to new understanding, always requiring new reading and new thinking.

The oldest (non-dead) source I could find was this 2008 post by someone else quoting Frum.

In Silicon Valley, [...] many of the more successful entrepreneurs seem to be suffering from a mild form of Asperger’s where it’s like you’re missing the imitation, socialization gene... It happens to be a plus for innovation, and creating great companies, but I think we always should turn this around as an incredible critique of our society. We need to ask, what is it about our society where those of us who do not suffer from Asperger’s are at some massive disadvantage because we will be talked out of our interesting, original, creative ideas before they are even fully formed?

To teach students any psychology they did not know before, you must surprise them. But which surprise will do? Nisbett and Borgida found that when they presented their students with a surprising statistical fact, the students managed to learn nothing at all. But when the students were surprised by individual cases—two nice people who had not helped—they immediately made the generalization and inferred that helping is more difficult than they had thought. Nisbett and Borgida summarize the results in a memorable sentence:

Subjects’unwillingness to deduce the particular from the general was matched only by their willingness to infer the general from the particular.

This is a profoundly important conclusion. People who are taught surprising statistical facts about human behavior may be impressed to the point of telling their friends about what they have heard, but this does not mean that their understanding of the world has really changed. The test of learning psychology is whether your understanding of situations you encounter has changed, not whether you have learned a new fact. There is a deep gap between our thinking about statistics and our thinking about individual case

Science has this in common with art, that the most ordinary, everyday thing appears to it as something entirely new and attractive, as if metamorphosed by witchcraft and now seen for the first time. Life is worth living, says art, the beautiful temptress; life is worth knowing, says science.

Nietzsche, Homer and Classical Philology, http://en.wikisource.org/wiki/Homer_and_Classical_Philology

There may be room for a few pure theorists... In my life I’ve met a few brilliant geniuses, very few, who could sit in an office and think great thoughts and contribute to the world. It’s a very small number, by the way. Then I’ve met lots of people who generalize, which doesn’t move me because I don’t find it helpful. I find it distracting, confusing, misguided, or misplaced.

For most of us mortals, I think the deep engagement in real problems is crucial. I wouldn’t want to train doctors without the medical students walking the wards with their mentors. I don’t like training economists without them grappling with real problems in real places and learning the complexity of the interacting physical, technological, political, economic, natural systems.

Jeffrey D. Sachs on the Future of Innovation, in conversation with Tyler Cowen.

3gwern6yQuestion for readers: Jeffrey Sachs is best known for two things - shock therapy for former communist countries trying to modernize, and the Millennium Village projects. Are these examples vindication or refutation of his quote here?

“What's up, Sarge? Do you want to live for ever?”

“Dunno. Ask me again in five hundred years.”

  • "Guards! Guards!", Terry Pratchett

What is the difference between describing 'how' and explaining 'why'? To describe 'how' means to reconstruct the series of specific events that led from one point to another. To explain 'why' means to find causal connections that account for the occurrence of this particular series of events to the exclusion of all others.

--Yuval Harari, Sapiens: A Brief History of Humankind

0Ben Pace6yIn a lot of cases, 'why' can hide a lot of different questions, and needs to be properly reduced.

Now on what condition is the use of hypothesis without danger?

The firm determination to submit to experiment is not enough; there are still dangerous hypotheses; first, and above all, those which are tacit and unconscious. Since we make them without knowing it, we are powerless to abandon them. Here again, then, is a service that mathematical physics can render us. By the precision that is characteristic of it, it compels us to formulate all the hypotheses that we should make without it, but unconsciously.

Henri Poincaré, "The Foundations of Science".

What great causes are deeply unpopular?

Peter Thiel 50m into the interview. He only wants to fund unpopular causes because he assumes popular causes are relatively well funded.

6Good_Burning_Plastic6yI dunno, much of the popularity of certain causes is just slacktivism.
-127chaos6yAlso, non-popular causes deserve to be considered before leaping all the way to the other end of the spectrum.
0James_Miller6yWhat if you only have time to consider a small number of charities. Might it be reasonable to only look at those for unpopular causes?
127chaos6yI mean, sure. But it's not as though this scenario much resembles such a case.
0[anonymous]6yThere are causes people like, and there are causes people want to signal liking as it makes them look good. The second tends to attract slacktivism.

Desirability is not a requisite of the truth darkmatter2525 source

0James_Miller6yDoes this conflict with the Litany of Tarski [http://wiki.lesswrong.com/wiki/Litany_of_Tarski]?
3Quill_McGee6yOn the contrary, this is what the Litany of Tarski states.
0James_Miller6yBut by the Litany of Tarski, I want to desire the truth, I want the truth to be desirable.
7gjm6yThe quotation (I take it) means: What you are saying (I take it) is: or maybe neither of which is the same as what the quotation deplores. And neither of these is in fact the same as what the Litany of Tarski recommends, which is Perhaps a few specific examples may help to clarify the distinctions. 2,3 versus 4: I desire to believe that I will be dead in a week if in fact I will be dead in a week (4). But I don't see any reason why I should want to be dead in a week (3), nor would I be glad of being dead in a week if I learned I would be (2). 2 versus 3: Perhaps there is something to be said for an attitude of acceptance, whereby once I know I will be dead in a week I adjust my mental attitudes so as to be accepting, or even glad (2). But that doesn't mean that ahead of time I should prefer being dead in a week to not being dead in a week, even if at that point it happens that I already have the aneurysm that's going to kill me (3). 1 versus 2: (Almost identical to 2 versus 3, above.) Perhaps, if I find that I shall be dead in a week, I should adopt a positive attitude to that fact. But that doesn't mean that being dead in a week should be something I find desirable if I don't know it's going to happen. 1 versus 3: These are both commenting on the question of whether our desires should match up with how the world is. But they have different focuses. #1 is saying that because they don't always match, we shouldn't use our desires as a guide to how the world is. But #3 is saying that we should use how the world is to help form our desires. Those are not necessarily in conflict.

If you can't feed your baby, then don't have a baby.

-Michael Jackson (Wanna be starting something)

4[anonymous]6yRight, just the thing they should have told those irrational pregnant women who ran away from the Eastern part of Ukraine.
-1HedonicTreader6yEven if we're willing to take it out of context like this, we might still consider it ethically undesirable to have kids in a time and place where military conflict or politically caused poverty is likely.
1[anonymous]6yI personally wouldn't decide to have kids in a warzone... But what context are you referring to? Is there any context outside of sudden, subjectively unlikely disaster where the quote is meaningful?
0HedonicTreader6y...but it's okay if others do it? How is that different from saying, "I personally woudn't decide to abuse children..." It was written by Michael Jackson. I don't think he was referring to sudden, subjectively unlikely disasters, but the personal material means of people deciding to become parents.
1Jiro6yIt's impossible to have children and do no actions whatsoever which are less than optimal for the children. Rather, people make--and have to make--tradeoffs between things being bad for the children and other considerations. There is an acceptable range of such tradeoffs. Having kids in a warzone falls in that range and abusing kids does not. And even if you think people making other tradeoffs are actually wrong rather than just making the tradeoffs based on different circumstances, there are degrees of being wrong and abuse is wrong to a greater degree.
-4HedonicTreader6yThe dominating distinction between our perspectives is that I don't think having kids in a warzone is an acceptable tradeoff, where you think it is. This is probably just an intuitive disagreement about the relative harm and benefit of being born into a warzone. I think it is clearly a very bad deal for the child, and to do it recklessly or out of selfishness in fact constitutes a form of child abuse. Of course, if you would actually rather be born into poverty or war, than not be born, you will disagree where the acceptable range lies. We do not disagree about the rest of the argument.
-1[anonymous]6yIs it the same to die without ever abusing children and to die childless?
-1Lumifer6yApplying this, humanity would have quietly died out a few thousand years ago...
0HedonicTreader6y2 responses: 1. It is possible that this would have been better overall. 2. Even if we reject 1, humanity was no where near extinction for thousands of years now. You can easily augment the underlying harm avoidance principle with a condition that it should not result in the extinction of intelligent life (assuming that intelligent life doesn't cause even more harm in the long run).
0Lumifer6yI don't think this is how the real world works.
1RichardKennaway6yWell, quite. What can we do about that? [http://lesswrong.com/lw/1e/raising_the_sanity_waterline/]
-1Lumifer6yWhat exactly is the problem you want to solve? :-/
0hairyfigment6yClearly. [http://lesswrong.com/lw/lzn/rationality_quotes_thread_april_2015/c9k5]
-3James_Miller6yBut what if I can get taxpayers to feed my baby?
5pianoforte6116yAf first I thought you doing that Redditesque sarcasm, in which you argue a straw man of the outgroup in a mocking way, which made me disappointed since the goal is signaling rather than discourse. However perhaps you are being serious? Are social services a valid means of feeding a baby, rendering the original quote not applicable in countries where social services exist? I think the answer is obviously yes, in that if social services are available, people are going to use them. Whether the should exist is a separate discussion.
2IlyaShpitser6yI think it's a law that if you fund something you get more of it. Serious discussion of safety nets, etc. already assumes some parasite response from the "ecosystem," takes it into account, and argues safety nets are still a good thing on net.
0Lumifer6yI think "unintended consequences" is a better analysis framework than "parasite response from the ecosystem". And speaking of, there is a recent paper discussed on MR [http://marginalrevolution.com/marginalrevolution/2015/04/declining-desire-to-work-and-downward-trends-in-unemployment-and-participation.html] which claims to show how safety nets drive down the decline in labor force participation and, in particular, that "the Clinton-era welfare reforms lowered the incentive to work".
0HedonicTreader6yIt certainly sounds less cynical, unless we use strong charity and see it in the most technical way possible. I think the most plausible use case for government-funded incentives to have extra kids is a wide consensus that a society doesn't have enough of them at the time, according to some economical or social optimum. But even this requires a level of cynicism in seeing kids as a means to an end.
1James_Miller6yI was being serious. Abstractly, if my doing X requires Y, but I don't have Y but I'm confident that if I do X the government will give me Y, then my lack of Y isn't much of a reason to forgo X.
2hairyfigment6yCan you also get them to pay for cryonics? I don't know if you consider cryonics worthwhile, but the point is that "feed" generalizes easily. * Urahara Kisuke
0HedonicTreader6yThe difference is that babies suffer if they starve, but not if they don't have cryonics. The badness of making an extra life comes from its suffering (+ negative externalities) [- positive externalities]
1TheOtherDave6yInteresting... can you say more about why you include a term in that equation for internal negative value (what you label "suffering" here), but not internal positive value (e.g., "pleasure" or "happiness" or "joy" or "Fun" or whatever label we want to use)?
0HedonicTreader6yI suppose it was because the original quote started with a negative framing, the assumption that the baby might not be fed. I think both birth and death are stressful experiences that are not worth going through unless there are compensating other factors. I don't think infants have enough of those if they die before they grow up. Also I suspect human life is generally overrated, and the positives of life are often used as an excuse to justify the suffering of others. I do not trust people to make a realistic estimate and act with genuine benevolence.

Magnificent phrases like 'inductive reactance' flow effortlessly from the lips of guys who can't cook hotdogs or find the flashing blue light in a K-mart store. That's important to keep in mind. It doesn't take a lot of brains to learn a few words. Parakeets and my a birds do it all the time. You can, too. It's not work, it's a game.

It would have been wiser for the English governing class to have called upon some other god. All other gods, however weak and warring, at least boast of being constant. But science boasts of being in a flux for ever; boasts of being unstable as water.
