Sometimes magic is just someone spending more time on something than anyone else might reasonably expect

--Teller (source)

0D_Malik
My experience has been that when people try to understand what went into a magic trick, they usually come up with explanations more complex than the true mechanism. Oftentimes a trick can be done either through an obvious but laborious method, or through an easy method, and people don't realize that the latter exists. (For instance, people posit elaborate mirror setups, or "moving the hand quicker than the eye", or armies of confederates, when in fact simple misdirection, forcing, palming, etc. suffice.)

This time he covered a lot more ground and was willing to talk about the mundane details of presidential existence. “You have to exercise,” he said, for instance. “Or at some point you’ll just break down.” You also need to remove from your life the day-to-day problems that absorb most people for meaningful parts of their day. “You’ll see I wear only gray or blue suits,” he said. “I’m trying to pare down decisions. I don’t want to make decisions about what I’m eating or wearing. Because I have too many other decisions to make.” He mentioned research that shows the simple act of making decisions degrades one’s ability to make further decisions. It’s why shopping is so exhausting. “You need to focus your decision-making energy. You need to routinize yourself. You can’t be going through the day distracted by trivia.”

I'm assuming many are already aware of this, but he's talking about decision fatigue here.

A lot of outcomes about which we care deeply are not very predictable. For example, it is not comforting to members of a graduate school admissions committee to know that only 23% of the variance in later faculty ratings of a student can be predicted by a unit weighting of the student's undergraduate GPA, his or her GRE score, and a measure of the student's undergraduate institution selectivity -- but that is opposed to 4% based on those committee members' global ratings of the applicant. We want to predict outcomes important to us. It is only rational to conclude that if one method (a linear model) does not predict well, something else may do better. What is not rational -- in fact, it's irrational -- is to conclude that this "something else" necessarily exists and, in the absence of any positive supporting evidence, is intuitive global judgment.

The late F.W.H. Myers used to tell how he asked a man at a dinner table what he thought would happen to him when he died. The man tried to ignore the question, but on being pressed, replied: "Oh well, I suppose I shall inherit eternal bliss, but I wish you wouldn't talk about such unpleasant subjects."

Curiosity was framed. Avoid it at your peril. The cat's not even sick. If you don't know how it works, find out. If you're not sure if it will work, try it. If it doesn't make sense, play with it until it does. If it's not broken, break it. If it might not be true, find out. And most of all, if someone says it is none of your business, prove them wrong.

-Seth Godin

If it doesn't make sense, play with it until it does. If it's not broken, break it.

I'm going to adopt at different social strategy and not be the obnoxiously nosy guy with no boundaries. Some things I'm curious about really aren't my business and actively seeking to uncover information that people try to keep secret is usually a personal (and often legal) violation. The terms 'industrial espionage' and 'stalking' both spring to mind.

Curiosity didn't kill the cat. The redneck with the gun killed it for tresspassing.

2Plubbingworth
As I was growing up around here, I discovered that there are certain curiosities which are always welcomed in this redneck sort of area. They include such lovely questions as; * "What church do you go to?" * 1. "You root for the home sport team, right?" 2. "...Do you follow sport at all?" 3. "Why not?!" (They progress like this the more you answer "No") * "Politics? Politics? Politics? Politics? Politics? Politics? POLITICS?" Any curiosity more complex than this is usually just there to serve these three topics. But if you answer correctly (cough) these questions three, it's basically like using the Konami Code or something. Just in case you're ever in the South.
0A1987dM
Now I'm curious about how the progression continues. (In Italy, I am asked what football (soccer) team I support all the time, but when I say “I used to support Juventus, but I haven't actually followed football in years” they usually leave it at that, and when they do ask me why and I say stuff like “I just don't enjoy it anymore” they never progress any further.)
3Plubbingworth
Usually I try to give similar answers that halt the line of conversation. "I've never cared for sports, I shouldn't play for health reasons, it's not interesting to me, I don't understand the point, I've got other things to do, my dog was killed by a rogue football and I've never been the same since that fateful day", etc. I've never actually answered "No" to the question "Why not?!", but I feel as though I should try, now... So, I've never really let it progress beyond that point. As a kid, I did that with both religion and politics, by giving noncommittal answers.

To succeed in a domain that violates your intuitions, you need to be able to turn them off the way a pilot does when flying through clouds. You need to do what you know intellectually to be right, even though it feels wrong.

There is an Ice-T quote here.

And who shows greater reverence for mystery, the scientist who devotes himself to discovering it step by step, always ready to submit to facts, and always aware that even his boldest achievement will never be more than a stepping-stone for those who come after him, or the mystic who is free to maintain anything because he need not fear any test?

“But can’t you just wave your hand and make all the dirt fly away, then?”

“The trouble is getting the magic to understand what dirt is,” said Tiffany, scrubbing hard at a stain. “I heard of a witch over in Escrow who got it wrong and ended up losing the entire floor and her sandals and nearly a toe.”

“That works,” said Tiffany, “but only if you wave them about on the floor with a scrubbing brush.”

And sometimes it's true with s/easier/harder/. ("feel compassion for".) Hence invertibility.
4[anonymous]
Well, yes, but the invertibility is conditional. Compassion is easier with a concrete person for a target. As is... idk. There's probably some (respect? romantic love? Loyalty?). Hate is easier with a diffuse target. As is, say, idolizing love, disgust, contempt, superiority, etc. The invertibility isn't in that you can flip "harder" to "easier" and then have it make just as much sense. You have to change the emotion too, which signifies that there is a categorization of emotions: useful! If you insist that this is invertible wisdom, then I must say you are misapplying the heuristic.

Hate is easier with a diffuse target.

Depends. A klansman may find it easy to hate "niggers" but much harder to hate his black neighbour. A literary critic who values her tolerance may it find difficult to hate an abstract group but can passionately hate her mother-in-law. I am not sure whether the difference stems from there being two different types of hate, or only from different causes of the same sort of hate.

Isn't the actually a and the an ?
4chaosmosis
I don't think hate is necessarily easier with a diffuse target. People hold personal grudges well. There's also the fact that there are sometimes legitimate reasons to hate specific people, but there are basically never legitimate reasons to hate entire groups of people.
0TheOtherDave
Can you summarize your understanding of legitimate reasons for hate? I'm not asking for examples, but rather for the principles that those examples would exemplify.
0chaosmosis
Semi-legitimate might be a better descriptor. If someone destroyed me or the ones I loved out of spite and took pleasure in it, I would probably hate them and probably feel that my hate was legitimate. If I went through any traumatic experience like torture or rape, I would probably come out of that with some hate. I'm an egoist, not a utilitarian (I have strong utilitarian preferences though). That probably has implications for this as well.

It is easier to control how you relate to a theoretical group than a concrete individual. If you believe it is proper to hate Creationists, you can do so with little difficulty. If you change your mind and think it is better to pity them, you can do that.

But if you landlady has actually helped or hurt you, and you know a strong emotional response isn't actually called for, you're going to have a very hard time not liking or hating her.

This point is also relevant to Eliezer's post on truth as correspondance. A belief can start unentangled with reality, but once people talk about it, the belief itself becomes part of the territory.

Yes, this. Other people's expressions of verbal symbols that are not even part of their map are also part of the territory.

Lastly, there is an attitude not unknown in the crisis against which I should particularly like to protest. I should address my protest especially to those lovers and pursuers of Peace who, very short-sightedly, have occasionally adopted it. I mean the attitude which is impatient of these preliminary details about who did this or that, and whether it was right or wrong. They are satisfied with saying that an enormous calamity, called War, has been begun by some or all of us; and should be ended by some or all of us. To these people this preliminary chapter about the precise happenings must appear not only dry (and it must of necessity be the driest part of the task) but essentially needless and barren. I wish to tell these people that they are wrong; that they are wrong upon all principles of human justice and historic continuity: but that they are specially and supremely wrong upon their own principles of arbitration and international peace.

These sincere and high-minded peace-lovers are always telling us that citizens no longer settle their quarrels by private violence; and that nations should no longer settle theirs by public violence. They are always telling us that we no longe

Two WAITWs don't make a right. In this quotation, Chesterton writes against people who compare war to vigilante justice. But his argument is not that this is a poor comparison, but that instead the analogy doesn't go far enough. So, he compounds the error of his opponents with an error of his own. There's also some scenario slippage -- in the peacenik argument, the citizen "avenges" himself, but by the time Chesterton gets to him, the dead man was just "standing there within reach of the hatchet." That alone gives you a hint about you what kind of hearing the accused is likely to get in Chesterton's court.

--Ambrose Bierce, The Devil's Dictionary
0MixedNuts
The international equivalent is not a police and justice system, it's vigilante justice. Doing nothing is not much worse than killing the attacker, being killed by the attacker's friends who believe the victim had started it, and starting a vendetta. How do you arrest a state? Ask the UN for permission to carpet-bomb it?

Under the assumption that a lesser power is unable to punish injustice done by a greater power, the three possible alternatives at any level of power are "Injustice is dealt with by a greater power", "Injustice is dealt with by peers", and "Injustice is dealt with by nobody". The first system sounds nice, except that infinite regression is impossible, and so eventually you end up at the greatest level of power, choosing between systems two and three. In that case, system two seems preferable, "vigilante" connotations notwithstanding.

I prefer this sort of distant, reductionist, structural approach to analysing the race because there's little reason to believe in the validity of the implicit theories or "models" lurking behind pundits' gut judgments. When I heard Mr Romney's 47% comments, I thought "Oooh, he's toast!" and then I stopped myself and acknowledged that I actually have no rational basis for believing that his remarks would in the final analysis hurt Mr Romney at all. What percentage of undecided or weakly-decided swing-state voters ever caught wind of Mr Romney's embarrassing chat? I didn't know! Of those who became aware of it, how many cared? I didn't know! So why did I think "Oooh, he's toast!" Because I am human, and I make most judgments and decisions on the basis of crackpot hunches, the underlying logic of which is almost completely inscrutable to me.

--Will Wilkinson

That comment did move Intrade shares by around 10 percentage points, I think, though I'm only going on personal before-and-after comparisons. The good Will may have picked the wrong time to criticize his instincts.

So? That just means that some of the people who trade on intrade also made the mistake Will alludes to.
2PlacidPlatypus
Nate Silver's model also moved toward Obama, so it's probably reflecting something real to some extent.
2Alejandro1
But the gains have been already cancelled by Romney's better performance in the first debate. You could spin this in two ways. One one hand, you could argue that the "47%" comment did move the polls, and that ceteris paribus it would have reduced significantly Romney's chances of winning. On the other hand, you could say that ceteris should not be expected to be paribus; polls are expected to shift back and forth, and regress to the mean (where "the mean" is dictated by the fundamentals--incumbency, state of the economy, etc), and that if 47% and the debate hadn't happened, other similar things would have.
2PlacidPlatypus
Silver's model already at least attempts to account for fundamentals and reversion to the mean, though. You could argue that the model still puts too much weight on polls over fundamentals, but I don't see a strong reason to prefer that over the first interpretation of just taking it at face value.

Has there been any analysis of how accurate Silver's predictions have been in the past?
5Alejandro1
He basically jumped to fame when he predicted the result of many of the Obama-Clinton primaries far more accurately than the pundits. He then got right 49 out of 50 states in Obama-McCain (missing only Indiana, where Obama won by 1%). He also predicted correctly all the Senate races in 2008 and all but one in 2010. In the House in 2010 the GOP picked just 8 seats more than his average forecast, which was well within his 95% confidence interval. (All info taken from Wikipedia.) I do not know of any systematic comparison between his accuracy and that of other analysts, but I would be surprised if there was someone better.

Despite the difficulty of exact Bayesian inference in complex mathematical models, the essence of Bayesian reasoning is frequently used in everyday life. One example has been immortalized in the words of Sherlock Holmes to his friend Dr. Watson: “How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?” (Arthur Conan Doyle, The Sign of Four, 1890, Ch. 6). This reasoning is actually a consequence of Bayesian belief updating, as expressed in Equation 4.4. Let me re-state it this way: “How often have I said to you that when p(D|θ_i ) = 0 for all i!=j, then, no matter how small the prior p(θ_j ) > 0 is, the posterior p(θ_j |D) must equal one.” Somehow it sounds better the way Holmes said it.

--Kruschke 2010, Doing Bayesian Data Analysis, pg56-57

When you have eliminated the impossible, whatever remains is often more improbable than your having made a mistake in one of your impossibility proofs.

-Steven Kaas (via)

5PhilGoetz
It always irritates me slightly that Holmes says "whatever remains, however improbable, must be the truth", when multiple incompatible hypotheses will remain. My Holmes says, "When you have eliminated the possible, you must expand your conception of what is possible."
3pragmatist
You have an inequality symbol missing at the end of the quote (between i and j). That made it slightly difficult for me to parse it on my first read-through ("Why does it say 'for all i, j' when the only index in the expression is 'i'?").
0WingedViper
I don't know if you know, but just in case you (or someone else) don't: There is no inequality symbol on the computer keyboard, so he used a typical programmer's inequality symbol which is "!=". So yes, it is not easily readable (i! is a bad combination...) but totally correct.

A space between variable & operator would help.
3pragmatist
The symbol wasn't there when I wrote my comment. It was edited in afterwards.
2A1987dM
The way to handle that is whitespace: i != 0. (I once was teased by my tendency to put whitespace in computer code around all operators which would be spaced in typeset mathematical formulas.) EDIT: I also use italics for variables, boldface for vectors, etc. when handwriting. Whenever I get a new pen I immediately check whether it's practical to do boldface with it.

Of course, an infitesimal prior dominating the posterior pdf might also be a hint that your model needs adjustment.

Frodo: Those that claim to oppose the Enemy would do well not to hinder us.

Faramir: The Enemy? (turns over body of an enemy soldier) His sense of duty was no less than yours, I deem. You wonder what his name is, where he came from, and if he was really evil at heart. What lies or threats led him on this long march from home, and if he'd not rather have stayed there... in peace. War will make corpses of us all.

-- The Lord of the Rings: The Two Towers (extended edition)

What Faramir says contains wisdom but so do Frodo's words. The enemy is trying to destroy the world with some kind of epic high fantasy apocalypse. Frodo does not terminally value the death (heh) of specific foot soldiers. They may be noble and virtuous and their deaths a tragic waste. But Frodo has something to protect and also has baddass allies who return from the (mostly) dead with a wardrobe change. But he doesn't have enough power to give himself a batman-like self-handicap of using non-lethal force. Killing those who get in his way (but lamenting the necessity) is the right thing for him to do and so yes, people would do well not to hinder him.

I'd ding you for having confessed to being proud of your ignorance, except that what you confessed ignorance of was not, technically speaking, a fact.
3NoSignalNoNoise
I'm never quite sure what to think about being proud of not knowing a fact. On one hand, knowledge itself almost certainly has positive value, even if that value is very small. On the other hand, making the effort to acquire very low-usefulness knowledge generally has negative expected utility, so I can understand prioritized a particular body of knowledge as "not worth it." Of course, pride is really about signaling, so it makes sense to look at what sort of signal one's pride is sending. If someone seems particularly knowledgeable about a low-status topic, such as celebrity gossip, I judge them negatively for it. I assume most people do this, though with different lists of which topics are low-status (or am I just projecting?). Ultimately, I think the questions to consider are: 1. As an individual, does prideful ignorance of a topic you consider not worthwhile send a signal you want to send, and 2. As a community, is this the sort of signal we want to encourage?

It's all fine and good to declare that you would have freed your slaves. But it's much more interesting to assume that you wouldn't have and then ask, "Why?"

A common mistake is to suppose that scientists are such admirable people that they can be safely entrusted with the ultimate responsibil­ity for guiding scientific research. In fact they are no more admirable than any other type of worker. Neither selection nor self-selection tor a scientific career is based on admirableness. Though the conventions and protocols of science enforce on scientists, in comparison to astrologers and English professors—and lawyers—a high degree of objec­tivity when they are doing science, it does not follow that such indi­viduals can be depended on to be objective policy analysts. That is a role for which they are not trained (but is anyone?) and that does not impose the constraints that science imposes.

From the leavings of memory and forgetfulness we could create a nearly complete map, I think, of a person's values. What you don't even see -- the subtle sadness in a colleague's face? -- and what you might briefly see but don't react to or retain, is in some sense not part of the world shaped for you by your interests and values. Others with different values will remember a very different series of events.

Paths are made by walking

-Franz Kafka (quoted in Joy of Clojure)

Caminante, son tus huellas
el camino, y nada más;
caminante, no hay camino,
se hace camino al andar.
Al andar se hace camino,
y al volver la vista atrás
se ve la senda que nunca
se ha de volver a pisar.
Caminante, no hay camino,
sino estelas en la mar.

-Antonio Machado

Translation:

Wanderer, your footsteps are
the road, and nothing more;
wanderer, there is no road,
the road is made by walking.
By walking one makes the road,
and upon glancing back
one sees the path
that must never be trod again.
Wanderer, there is no road—
Only wakes upon the sea.

He has a point. It isn't obvious that Dawkins' objection doesn't apply to math. The ontological argument probably has more real-world assumptions used in it than does arithmetic.

To think only of winning is sickness. To think only of using the martial arts is sickness. To think only of demonstrating the results of one's training is sickness, as is thinking only of making an attack or waiting for one. To think in a fixated way only of expelling such sickness is also sickness. Whatever remains absolutely in the mind should be considered sickness. As these various sicknesses are all present in the mind, you must put your mind in order and expel them.

It kinda backfired at first because I started over-planning the details of my daily activities, like ya do. And anything I actually took an interest in, to quell my confusion and streamline my time, drew people towards me for my arcane skills. Is there any honor in hiding your abilities (when it's not your job) so people don't ask for help with simple stuff? I was... uh... the family IT guy. My dad still needs the computer's power button pointed out to him.

Place a notebook next to the computer. When you tell someone how to do something, tell them to write it down, every step, in the notebook. Tell them to write it down so that they will be able to understand it later. Next time they ask you the same question, refer them to the notebook. If this fails to help, consider insisting on some minor cost (such as 'buy me a chocolate' - nothing expensive, more an irritant than anything else, merely a cost for the sake of having a cost) for reiterating anything that has been written in the notebook. It may or may not help, but if it doesn't help, then at least you'll get a certain amount of chocolate out of it.
