Politics, after all, is the art of persuasion; the political is that dimension of social life in which things really do become true if enough people believe them. The problem is that in order to play the game effectively, one can never acknowledge this: it may be true that, if I could convince everyone in the world that I was the King of France, I would in fact become the King of France; but it would never work if I were to admit that this was the only basis of my claim.
politicians and leaders worldwide don’t like to be associated with toilets, even state-of-the-art toilets. This sanitation stigma distorts international and national development agendas.

The quote was brought to my attention by a student in my Economics of Future Technology course who is writing on sanitation in the developing world.
Nor of course must they ever be allowed to raise Aristotle’s question: whether “democratic behaviour” means the behaviour that democracies like or the behaviour that will preserve a democracy. For if they did, it could hardly fail to occur to them that these need not be the same.
(..)
Even if they don’t read Aristotle (that would be undemocratic) you would have thought the French Revolution would have taught them that the behaviour aristocrats naturally like is not the behaviour that preserves aristocracy. They might then have applied the same principle to all forms of government.

Hayek was right. Capitalists in a mixed-economy seem to be in something analogous to a prisoner's dilemma. It would benefit any individual capitalist to seek monopoly privileges for their own firm, but it hurts all of them if any significant number of them do so.
Among a great many other things that chess teaches you is to control the initial excitement you feel when you see something that looks good. It trains you to think before grabbing, and to think just as objectively when you're in trouble. When you're making a film you have to make most of your decisions on the run, and there is a tendency to always shoot from the hip. It takes more discipline than you might imagine, to think, even for thirty seconds, in the noisy, confusing, high-pressure atmosphere of a film set. But a few seconds' thought can often prevent a serious mistake being made about something that looks good at first glance. With respect to films, chess is more useful in preventing you from making mistakes than giving you ideas. Ideas come spontaneously and the discipline required to evaluate and put them to use tends to be the real work.

It has been said that the past is a foreign country. Well, it is certainly inhabited by foreigners, people whose mindset was shaped by circumstances we shy from remembering. The mother of three children who gave birth eight times. The father of four children, the last of whom cost him his wife. Our minds are largely free of such horrors, and not inured to that kind of suffering. That is the progress of technology. That is what is improving the human race.
It is a long, long ladder, and sometimes we slip, but we've never actually fallen. That is our progress.
The past is in some respects worse than a third world country. In the United States around 1900, the life expectancy ranged from around 50 climbing steadily to reach around 60 around 1930 (curiously the Great Depression didn't cause a slump in life expectancy, although the rate of growth did slow). Source with related data(pdf). But, if one looks at current life expectancy in many countries in the developing world, most countries exceed the US-1900 numbers. Similar comparisons can be made for literacy and many other metrics of success. The middling developing countries today are better in many ways than most of the US was in 1900.
Also, third world countries can buy the used stuff we don't want anymore. The past can't do that.
You might expect that, having learned of the existence of immortal life, man would dedicate colossal resources to learning how the immortal jellyfish performs its trick. You might expect that biotech multinationals would vie to copyright its genome; that a vast coalition of research scientists would seek to determine the mechanisms by which its cells aged in reverse; that pharmaceutical firms would try to appropriate its lessons for the purposes of human medicine; that governments would broker international accords to govern the future use of rejuvenating technology.

I was once, years and years ago, falsely accused by someone of egregious dishonesty, and after I put forward evidence that the accusation was false, was told, "Let's just agree to disagree." At which, of course, I exploded; I would not be agreeing to disagree about whether I had been completely dishonest, thank you very much. And every time someone uses the phrase I am tempted to say, "We don't need to agree to disagree because we already are disagreeing." I think what gets me is that it's such an unbelievably low standard that almost anything would be more intellectually robust; why not agree to something more ambitiously intellectual, like swapping book recommendations, or having a temporary cooling-off period, or going to a third party for arbitration or advice, or anything else, really?
I thought that "agree to disagree" had become a fixed expression meaning something like "stop discussing this for now even though we don't agree, because we have more productive things to do/talk about".

...Anyone who values truth should stop worshipping reason. We all need to take a cold hard look at the evidence and see reasoning for what it is. ... [M]ost of the bizarre and depressing research findings [about cognitive biases] make perfect sense once you see reasoning as having evolved not to help us find the truth but to help us engage in arguments, persuasion, and manipulation in the context of discussions with other people.
I'm not saying we should all stop reasoning and go with our gut feelings. Gut feelings are sometimes better guides than reasoning for making consumer choices and interpersonal judgments, but they are often disastrous as a basis for public policy, science, and law. Rather, what I'm saying is that we must be wary of any /individual/'s ability to reason. We should see each individual as being limited, like a neuron. A neuron is really good at one thing: summing up the stimulation coming into its dendrites to 'decide' whether to fire a pulse along its axon. A neuron by itself isn't very smart. But if you put neurons together in the right way you get a brain; you get an emergent system that is much smarter and more flexible than a single neuron.

In December of each year, the New York Times film critics, like film critics everywhere, write Deep Think pieces about what patterns in the movies released in the current year tell us about Trends in the Big Issues. The annual answer ought to be: Virtually nothing, because what gets released in a single year is a close to a random sample of projects that had been in the works for years and happened to come to fruition now. But that never stops the critics from pontificating on 2012: The Meaning of It All.

"It's frightening to think that you might not know something, but more frightening to think that, by and large, the world is run by people who have faith that they know exactly what is going on." - Amos Tversky
One in four Americans has an opinion about an imaginary debt plan
A new poll from Public Policy Polling found that an impressive 39 percent of Americans have an opinion about the Simpson-Bowles deficit reduction plan.
Before you start celebrating the new, sweeping reach of the 2010 commission’s work, consider this: Twenty-five percent of Americans also took a stance on the Panetta-Burns plan.
What’s that? You’re not familiar with Panetta-Burns? That’s probably because its “a mythical Clinton Chief of Staff/former western Republican Senator combo” that PPP dreamed up to test how many Americans would profess to have an opinion about a policy that did not exist. They found one in four voters to do just that.
Panetta-Burns’ nonexistent policy proposals were supported by 8 percent and opposed by 17 percent of the voters surveyed. Simpson-Bowles’ real policy proposals had stronger favorables, with 23 percent support and 16 percent opposition.
Devil's advocate time:
They don't know nothing about it. They know two things.
Here are some reasons to oppose the plan, based on the above knowledge:
We don't need a debt reduction plan, just keep doing what we're doing and it will sort itself out.
I like another existing plan, and this is not that one, so I oppose it.
I've heard of Panetta and (s)he's a complete douchebag. Anything they've come up with is clearly junk.
I haven't even heard of either of them, so what the heck would they know about debt reduction?
They're from different parties, there's no way they could have come up with something sensible.
I've heard 10 different plans described, and surely this is one of them. I can't remember which one this is, but I hated all of them so I must oppose this too.
And of course you can make a very similar set of reasons to support it. Not trying to rationalise people's stupidity or make excuses for them as such, just present the opposing argument in all its glory. Ok maybe making excuses for them is exactly what I'm doing. But honestly, how many of your political opinions, as a percentage, including all those that you don't know you have until asked, are really much better than the reasons above?
This might be a distinction without a difference. The trick was to get people to think they knew about some topic X well enough to profess an opinion on it, even though in fact they didn't know the first thing about X. Making sure that X doesn't exist is just a cheap way to implement this trick.
Long quote to make a simple point, but relevant. (Context: this is from a Star Wars novel, so it's fiction.)
...A death hollow is a low point where the heavier-than-air toxic gases that roll downslope from the volcanoes can pool.
The corpse of a hundred-kilo tusker lay just within its rim, its snout only a meter below the clear air that could have saved it. Other corpses littered the ground around it: rot crows and jacunas and other small scavengers I didn't recognize, lured to their deaths by the jungle's false promise of an easy meal.
I said something along these lines to Nick. He laughed and called me a Balawai fool.
"There's no false promise," he'd said. "There's no promise at all. The jungle doesn't promise. It exists. That's all. What killed those little ruskakks wasn't a trap. It was just the way things are."
Nick says that to talk of the jungle as a person-to give it the metaphoric aspect of a creature, any creature-that's a Balawai thing. That's part of what gets them killed out here.
It's a metaphor that shades the way you think: talk of the jungle as a creature, and you start treating it like a creature. You start thinking you can outsmart the jungle, or tr
...A person is said to exhibit rational irrationality when it is instrumentally rational for him to be epistemically irrational. An instrumentally rational person chooses the best strategies to achieve his goals. An epistemically irrational person ignores and evades evidence against his beliefs, holds his beliefs without evidence or with only weak evidence, has contradictions in his thinking, employs logical fallacies in belief formation, and exhibits characteristic epistemic vices such as closed-mindedness. Epistemically irrational political beliefs can reinforce one’s self-image; boost one’s self-esteem; make one feel noble, smart, superior, safe, or comfortable; and can help achieve conformity with the group and thus facilitate social acceptance. Thus, epistemic irrationality can be instrumentally rational.

It might make me feel patriotic; serve my xen
Well,
it is exactly what the quote said:
The cost to the typical voter of voting in epistemically irrational ways is nearly zero. The cost of overcoming bias and epistemic irrationality is high. The psychological benefit of this irrationality is significant. Thus, voters demand a high amount of epistemic irrationality.
In the case of LW, voting irrationally has almost zero costs. You don't get penalized for voting wrongly(Incidentally I suggested trying to implement some measure of this kind and guess what... I was downvoted). The penalties are more indirect, like diminishing the amount of epistemically correct contributions.
So why would you assume that LW would be less prone to have this sort of problem?
The evidence suggests that the problem should actually be worse on LW, see1, 2.
When you have run the length of various practices and none of those practices remain in your mind, that very lack of mind itself is the heart of "all things." When you have exhaustively learned the various practices and techniques and made great effort in disciplined training, there will be action in your arms, legs, and body but none in your mind; you will have distanced yourself from training, but will not be in opposition to it, and you will have freedom in whatever techniques you perform. You yourself will be unaware of where your mind is, and neither demons nor heresies will be able to find it.

It is very difficult to find a black cat in a dark room, especially if the cat is not there.
— Confucius, allegedly (quoted in The Meeting Place Cannot Be Changed)
Edit: The rationality relevance might need some explanation. The way I've seen this aphorism used is this: it's sometimes hard to distinguish between a task that's achievable but very difficult (and that it therefore might make sense to spend time/effort on), and a task that is impossible (and thus is a complete waste of time/effort).
If you spend some time searching for the cat in the dark room, you might not find it. Is that because finding it is difficult (after all, this is what you might quite plausibly expect, if you assume that the cat is there), or because the cat is not there and you're wasting your time?
It’s easier to do trivial things that are urgent than it is to do important things that are not urgent, like thinking; and it’s also easier to do little things we know we can do than to start on big things that we’re not so sure about.
Do not read written works and think, "This is the Way." Written works are like the gate to approach the Way. Thus, there are people who remain ignorant of the Way regardless of how much they have learned and how many Chinese characters they know. Though they face the pages and read as skillfully as though they were annotating the ancients, they are ignorant of the truth and so do not make the Way their own.
— Yagyū Munenori, The Life-Giving Sword
Nevertheless, it is quite difficult to approach the Way without studying. Still, one cannot say that a man embodies the Way simply because he has studied and speaks well. There are also people who are naturally in harmony with the Way and who have never studied at all.

"So have I," said Valentine. "But the trouble is that man, or in any case the common man, easily overcomes this need for knowledge of his. It seems to me that he doesn't have such a need at all. There's a need to understand, but knowledge is not required for that. The God hypothesis, for instance, gives one an unparalleled ability to understand absolutely everything, while discovering absolutely nothing...

But are we asking too much when we declare that our drugs need to work through single defined targets? Beyond that, are we even asking too much when we declare that we need to understand the details of how they work at all? Many of you will have had such thoughts (and they've been expressed around here as well), but they can tend to sound heretical, especially that second one. But that gets to the real issue, the uncomfortable, foot-shuffling, rather-think-about-something-else question: are we trying to understand things, or are we trying to find drugs?

...I don't have any previous experience with this sort of thing, but judging from what I hear and read, I'm supposed to be asking why all this is happening, and why it's happening to me. Honestly, those questions are about the farthest thing from my mind.
Partly, that’s because they aren't hard questions. Why does our world have gravity? Why does the sun rise in the East? There are technical answers, but the metaphysical answer is simple: that’s how reality works. So too here. Only in the richest parts of the rich world of the twenty-first century could anyone entertain the thought that we should expect long, pain-free lives. Suffering and premature death (an odd phrase: what does it mean to call death "premature"?) are constant presences in the lives of most of the peoples of the Earth, and were routine parts of life for generations of our predecessors in this country—as they still are today, for those with their eyes open. Stage 4 cancers happen to middle-aged men and women, seemingly out of the blue, because that's how reality works.

...The basic mission for which the police exist is to prevent crime and disorder.
The ability of the police to perform their duties is dependent upon the public approval of police actions.
Police must secure the willing co-operation of the public in voluntary observation of the law to be able to secure and maintain the respect of the public.
The degree of co-operation of the public that can be secured diminishes proportionately to the necessity of the use of physical force.
Police seek and preserve public favour not by catering to public opinion, but by constantly demonstrating absolute impartial service to the law.
Police use physical force to the extent necessary to secure observance of the law or to restore order only when the exercise of persuasion, advice, and warning is found to be insufficient.
Police, at all times, should maintain a relationship with the public that gives reality to the historic tradition that the police are the public and the public are the police; the police being only members of the public who are paid to give full-time attention to duties which are incumbent upon every citizen in the interests of community welfare and existence.
Police should always direct their

-- Sherlock (BBC series), season 1, episode 3 "The Great Game"
Yes, I know that if you correct for differences in caring due to distance/scope insensitivity/etc. it does help save them, and that caring doesn't preclude skepticism about which actions are helpful, and that in this particular case Sherlock should have refused to respond to blackmail and there'd have been fewer deaths. But it works as a retort to "can't say no" spending. Don't give to some counterproductive charity because you care about starving kids in Africa, give to the Against Malaria Foundation because it makes fewer kids dead.

The exposure of truth sometimes results in tragedy. However, no matter how tragic the truth may be, it would be an even greater tragedy to avert one's eyes from it.
If you are hiding in a basement from the Nazis, this isn't true. If you are going to be tortured for the whereabouts of people hiding from the Nazis, you should also avert your eyes and avoid finding out where they are hiding. The fact that instrumental and epistemic rationality are sometimes at odds is another tragic truth.
Just remember, most people most of the time are not about to learn the location of a refugee just before being tortured by Nazis.

The "mountain-sea" spirit means that it is bad to repeat the same thing several times when fighting the enemy. There may be no help but to do something twice, but do not try it a third time. If you once make an attack and fail, there is little chance of success if you use the same approach again.

Stripped to its essentials, every decision in life amounts to choosing which lottery ticket to buy. . . . Most organisms don't buy lottery tickets, but they all choose between gambles every time their bodies can move in more than one way. They should be willing to 'pay' for information---in tissue, energy, and time---if the cost is lower than the expected payoff in food, safety, mating opportunities, and other resources, all ultimately valuated in the expected number of surviving offspring. In multicellular animals the information is gathered and translated into profitable decisions by the nervous system.
Perhaps there is nothing in Nature more pleasing than the study of the human mind, even in its imperfections or depravities; for, although it may be more pleasing to a good mind to contemplate and investigate the application of its powers to good purposes, yet as depravity is an operation of the same mind, it becomes at least equally necessary to investigate, that we may be able to prevent it.

In the matter of reforming things, as distinct from deforming them, there is one plain and simple principle; a principle which will probably be called a paradox. There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, “I don’t see the use of this; let us clear it away.” To which the more intelligent type of reformer will do well to answer: “If you don’t see the use of it, I certainly won’t let you clear it away.
