I think we could modify our sense of it to mean that if you are down to having to accept a 0.01% probability, because you've excluded everything else, then it's probably better to go back over your logic and see if there's any place you've improperly limited your hypothesis space.

Several paradigm-changing theories introduced concepts that would have previously been thought impossible (like special relativity, or many-worlds interpretation)

At home there was a game that all the parents played with their children. It was called, What Did You See? Mara was about Dann’s age when she was first called into her father’s room one evening, where he sat in his big carved and coloured chair. He said to her, ‘And now we are going to play a game. What was the thing you liked best today?’
At first she chattered: ‘I played with my cousin . . . I was out with Shera in the garden . . . I made a stone house.’ And then he had said, ‘Tell me about the house.’ And she said, ‘I made a house of the stones that come from the river bed.’ And he said, ‘Now tell me about the stones.’ And she said, ‘They were mostly smooth stones, but some were sharp and had different shapes.’ ‘Tell me what the stones looked like, what colour they were, what did they feel like.’
And by the time the game ended she knew why some stones were smooth and some sharp and why they were different colours, some cracked, some so small they were almost sand. She knew how rivers rolled stones along and how some of them came from far away. She knew that the river had once been twice as wide as it was now. There seemed no end to what she knew, and yet her father had not told h

A long one:

. . . once upon a time men lived among the giants, who were like themselves but far more powerful, and these giants always had a supply of bread, fruit, milk, and all that was necessary to sustain life, which they must have acquired in ways that cost them little, for they would always give away their goods to whoever knew how to please them. And the giants would also carry them wherever they wanted to go, provided they asked in the proper way. So it came about that men never thought of working, nor of walking, nor of building wagons or ships; instead they became natural orators, and spent all of their time watching the giants, figuring out what would please or displease them, smiling at them or imploring them with tears in their eyes; or else simply pronouncing the necessary words, which had to be memorized exactly, though they had no understanding of the changes of humor that would come over the giants, their brusque refusals, or their sudden willingness. Now, if some man, in those days, had tried to get something for himself by his own industry, they would have laughed him to scorn; for the results of his labor would have been puny beside the immense provisions th

4[anonymous]14y

I thought it was a Marxist parable, or something of the sort...an allegorical critique of capitalism, supervalue, the elite exploiting the masses. I must be in a bad mood because of the Cathie Black situation in NYC...where the "giants" are the democratic masses, who protested against the natural orators of our government... Last night was a "change of humor that would come over the giants"... a "brusque refusal"...but in the end the middle/lower classes "seemed nevertheless to be charged with nourishing them and housing them and transporting them, and who eventually carried out their duties, provided they were prayed to" (the "praying" being only the making of promises, "I stand for the middle class", "we'll create jobs for you", "think of the children!!11!!1!"). The masses do, at times, crush the endeavors of the orators (more than one reference to Egypt was made last night)...but for the most part the giant masses do what they are told, as long as they hear the right things, and have a cookie or a coo tossed to them now and then. I freely admit taking too much liberty with all of that...but it really is what I was thinking about as I read it.

[-]Eneasz14y210

I guess I'm far too literal-minded. The whole time I simply assumed the giants were a normal God parable. I was rather non-plussed about the whole quote until I saw "A meditation on childhood" and then my head exploded. I don't even remember being a kid anymore.

4CronoDAS14y

I saw it coming before I read the line that explicitly mentioned childhood.

5Costanza14y

On the next page in the book, the author mentions, "I decided to go through with the fiction of the giants, although the reader will have seen by the third line where I was leading him." Personally, I didn't see it coming when I first read it. My first reaction was pretty much the same as Eneasz'.

0false_vacuum14y

Me too.

[-]wedrifid14y160

This was wasted as a point about 'gods'. The commentary on human social instincts irrespective of belief in literal gods was far more insightful.

[-]Armok_GoB14y130

Ok, so it seems almost everyone got a different idea of who the giants and the men were. Children and adults, pets and humans, humans and gods, governments and populations (in both directions!), humans and computers...

My first impulse upon seeing this, is that this must be a very general phenomena that occurs in a great spectrum of situations. That all these different situations are isomorpic towards one another. The next is that we should come up with a generalized theory for the concept and maybe make up a word to access the concept quicker.

8SRStarin14y

I didn't know where it was going at all until I hit the words "instead they became natural orators." It was a that point that I thought of my 17-month-old daughter. Thank you for a very timely message.

6gwern14y

Hah; I read through that entire thing expecting the punchline to be that the giants were computers.

2Costanza14y

Maybe one day they will be. Or we will be, or they'll make paperclips of us all.

4AngryParsley14y

For most of the time I spent reading this quote, I thought the men were celebrities or demagogues and the giants were the populace.

Day ends, market closes up or down, reporter looks for good or bad news respectively, and writes that the market was up on news of Intel's earnings, or down on fears of instability in the Middle East. Suppose we could somehow feed these reporters false information about market closes, but give them all the other news intact. Does anyone believe they would notice the anomaly, and not simply write that stocks were up (or down) on whatever good (or bad) news there was that day? That they would say, hey, wait a minute, how can stocks be up with all this unrest in the Middle East?

--Paul Graham

8simplyeric14y

An interesting concept...but I wonder. I bet at least some people would actually notice that. They'd see unrest in the middle east and say "hmm...oil prices didn't change the way I expected them to" or something. Sometimes you see things like " index rises in spite of ". I think Graham's inference has merit: these people don't really know what's happening...but I think some people at least would notice the anomoly.

[-]benelliott14y110

Well now I want to test this. Do we have anyone here who thinks they know a thing or two about the stock market? If so would they be amenable to an experiment?

I'm thinking that they would agree not to look at any stock price information for a day (viewing all the other news they want). At the end of the day they are presented with some possible sets of market closes, all but one of which of which are fake, and we see if they can reliably find the right one.

2Gurkenglas11y

Finding the most probable market outcome given a few possibilities and a day's news is easier than noticing by yourself that the news and the market don't fit.

2benelliott14y

I'm benelliott3 at gmail. To be honest I'm not very familiar with the stock-market so if you could suggest a procedure for the experiment, including such things as where to get the information that would be appreciated. Care to precommit to a discussion post about the experiment regardless of the result?

6private_messaging11y

Well, the time Steve Ballmer announced he was to quit the Microsoft, Microsoft's stock jumped quite a bit, clearly because Ballmer quit, even though one could perhaps explain either a raise or a fall with Ballmer quitting. Expected square of a change was big from Ballmer quitting, that's for sure. Same goes for any dramatic news, such as the recent gas attack in Syria. And yes, over the time one could tell that something is up if the stock market graph is uneventful while there's dramatic news. Bottom line is, a causal link can exist and be inferred even when there is no correlation.

"Great is Bankruptcy: the great bottomless gulf into which all Falsehoods, public and private, do sink, disappearing; whither, from the first origin of them, they were all doomed. For Nature is true and not a lie. No lie you can speak or act but it will come, after longer or shorter circulation, like a Bill drawn on Nature's Reality, and be presented there for payment, - with the answer, No effects.
Pity only that it often had so long a circulation: that the original forger were so seldom he who bore the final smart of it! Lies, and the burden of evil they bring, are passed on; shifted from back to back, and from rank to rank; and so land ultimately on the dumb lowest rank, who with spade and mattock, with sore heart and empty wallet, daily come in contact with reality, and can pass the cheat no further.
[...]
But with a Fortunatus' Purse in his pocket, through what length of time might not almost any Falsehood last! Your Society, your Household, practical or spiritual Arrangement, is untrue, unjust, offensive to the eye of God and man. Nevertheless its hearth is warm, its larder well replenished: the innumerable Swiss of Heaven, with a kind of Natural loyalty, gather round it;

There is no greater joy than riding the words of Thomas Carlyle. He may not always be correct (although his point above is a blow of hard-hitting truth as great as any ever written) but his phrasing, his metaphors, his analogy, are all magnificent.

-3SilasBarta14y

But ... but ... what about bankruptcies induced by a liquidity crunch -- the kind the political elite's propagandists have have been telling me entitle a "too big to fail" company to receive perpetual government assistance? In those cases, bankruptcy wouldn't suck up falsehoods, would it?

6gwern14y

No. But I think you* are guilty of affirming the consequent. If something is false, then it will end in bankruptcy - but that does not logically imply that everything ending in bankruptcy was false. So something true could still end in bankruptcy (for whatever reason, like a liquidity crunch). * Or Carlyle, I suppose, but given the choice between accusing a famous thinker of an elementary fallacy and a quick off-the-cuff Internet comment, I'd rather accuse the latter.

0BillyOblivion14y

If your business is structured such that a liquidity crunch will drive you bankrupt then some restructuring might be in order. Now one can (and I certainly would be willing) to make the argument that it is almost impossible for a small to medium sized business to structure itself such that a liquidity crunch exacerbated by an inept political class and a rapacious bureaucracy (or a rapacious political class and an inept bureaucracy, whatever). In that case it's best to take your ball and go home leaving the enlightened revolutionaries with the society they voted for.

-2SilasBarta14y

Eh, that's what I thought do, but the very idea looks to be beyond the pale. They tell me that we needed to make huge loans on terms no one else could get to prop up some large banks, and it's "only" to provide "liquidity". But my thought is: I find it extremely unsettling to be in an economy where such a huge fraction of it is based on business plans this brittle; and the sooner and more spectacularly they die off, the better a foundation future growth will be built on. But current mainstream thinking doesn't even allow such a thought. I also saw people present, as "evidence" of a liquidity crunch, the fact that overnight lending rights spiked from 4% to 6% annualized. Considering that these are the annualized rates for loans with a life of a few weeks at most, this is a trivial increase in borrowing costs. A business so fragile that it can't withstand paying a few extra pennies for ultra-cheap loans every once in a while ... well, any economy dependent on such brittle business plans is living on borrowed time anyway.

"Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered.
We should forget about small efficiencies, say about 97% of the time; premature optimization is the root of all evil."

A premature really powerful Optimization Process is the root of all future evil.

8CronoDAS14y

"The first rule of code optimization: Don't."

4imaxwell14y

I never thought of this quote outside the context of programming before reading it here, but it does seem pretty generally applicable. The force behind premature optimization is the force that causes me to spend so much time comparison shopping that the time lost eventually outvalues the price difference; or to fail to give money to charity at all because there may be a better charity to give it to. (I've recently started donating the dollar to Vague Good Cause at stores and restaurants when asked, because it's all well and good to say "SIAI is better," but that defense only works if I then actually give the dollar to SIAI.)

Just saw on reddit a perfect accidental metaphor: jakeredfield posted this in r/gaming:

For the people that have no played Portal yet, be warned, there may be spoilers up ahead for you.
So anyway, I am a huge fan of Portal, I love everything about the game. I bought it upon release and have played through it multiple times. My friends aren't as big of gamers as me so it took them some time to get their hands on Portal. My one friend didn't have a computer capable of running Portal so I let him play on mine.
I pulled up a chair besides him and eagerly watched him play then entire time. He loved the game. I expected him to. It's an awesome game. But here comes the WTF part...(SPOILERS AHEAD)
He go to the part at the last puzzle, right before GlaDOS tries to kill you in the fire. So then, my friend is like, "Oh, so it's one of those games where you die at the end. Haha, it was a good game." And then he immediately shuts it down. I just sat there. Shocked. In awe. I couldn't believe what I just saw. He turns to me and goes, "Good game, I'd play that again."
This is the part where I just hit him and yell, "IT WASN'T OVER YET!" He was so confused. He loaded it

1roryokane14y

Can you give some examples of when that has happened? I’m having trouble of thinking of any. The widespread use of computers seems to have been a great success, on the whole.

5gwern14y

Who said it was about computers per se? I didn't. I was personally thinking more of electricity and radiation. Electric belts! Electroshock therapy! Electric toothbrushes! The mind as a power grid! Radium salt supplements! Radioactive watches! Well actually we still use tritium for that. (Or to take a more recent example, microfilm. "Let's put everything on microfilm and shred all the original newspapers and books! What could possibly go wrong?") We may be a little too close to the computer to see the silliest and most grotesque solutions it has provided, although The Daily WTF may be a good start.

0roryokane14y

I know you didn’t mention computers; it was just the first example that came to mind. It seemed like if the quote would apply to anything, it would apply to computers most of all, but it didn’t. But good points about electricity and about being computers being too recent.

The IoT (internet of things) comes to mind. Why not experience WiFi connectivity issues while trying to use the washing machine? Everything trying to become a subscription service is another example (possibly related to IoT).

The company is called Klim, and in fairness, the user can check whether the airbag is ready for use, before getting on their bike.

"I submit that claims about God are of this latter sort. There’s simply no reason to take them more seriously than one does claims about witches or ghosts. The idea that one needs powerful philosophical theories to settle such issues I like to call the “philosophy fallacy.”

We will see that people are particularly prey to it in religious discussions, both theist and atheist alike; indeed, atheists often get trapped into doing far more, far riskier philosophy than they need."

--Georges Rey, "Meta-atheism: Religious Avowal as Self-deception" (2009)

(First version seen on http://www.strangedoctrines.com/2008/09/risky-philosophy.html but quote from an expanded paper.)

[-]ata14y190

It's true that the question of God's existence is epistemologically fairly trivial and doesn't require its own category of justifications, and it's also true that even many atheists don't seem to notice this. But even with that in mind, it almost never actually helps in convincing people to become atheists (most theists won't respond to a crash course in Bayesian epistemology and algorithmic information theory, but they sometimes respond to careful refutation of the real reasons they believe in God), which is probably why this point is often forgotten by people who spend a lot of time arguing for atheism.

-2ChristianKl14y

Choosing good priors isn't something that's epistemologically fairly trivial. Using the majority opinion of the human race as a prior is a general strategy that you can defend rationally.

If a given hypothesis is incoherent even to its strongest proponents, then it's not very meritorious. It's in "not even wrong" territory.

1Will_Newsome14y

I strongly suspect that there is a lot of coherence among many different spiritualists' and theologians' conception of God, and I strongly suspect that most atheists have no idea what kind of God the more enlightened spiritualists are talking about, and are instead constructing a straw God made up of secondhand half-remembered Bible passages. In general I think LW is embarrassingly bad at steel-manning.

Coherence isn't necessary factor for a good theory. In artificial intelligence it's sometimes preferable to allow incoherence to have higher robustness.

It's Georges Rey. I know because I sat through an entire class that he taught once. I think I also read his book, Contemporary philosophy of mind: a contentiously classical approach, during that time, but I don't recall learning anything from it. Can someone who has actually read the paper (I don't feel like it) tell me whether it has the same upshot as the earlier version I seem to remember, viz. that people only pretend to believe in God? (It's possible I've got this mixed up with something else.)

Unknown source. But I'm not sure what any of the variants of this have to do with rationality.

0TheOtherDave13y

Well, a lot of instrumental-rationality posts around here are basically about the benefits of devoting effort in the short term to developing techniques for making a class of task easier, rather than devoting effort in the short term to implementing an instance of that class with more difficulty. Also, efficient charity is a recurring theme. Whether either of those things have much to do with rationality is a broader question, but they certainly seem relevant to the quote.

"But can people in desperate poverty be considered to be making free choices? Many say no. So, is the choice between starving and selling one’s kidney really a choice? Yes; an easy one. One of the options is awful. To forbid organ selling is to take away the better choice. If we choose to provide an even better option to the person that would be great – but it is no solution to the problem of poverty to take away what choices the poor do have absent outside help."

7JoshuaZ14y

I don't like this quote. It is amusing but not very rational. It is not rational to ignore arguments because they were made by an awful person. It also isn't rational even if one thinks that an argument or set of ideas is not worth thinking about to actively refuse to discuss those ideas, even if one thinks that the ideas aren't worth considering. The first part of the quote is marginally defensible if Popper is very sure that Heidegger's ideas are a waste of time. The second part of the quote, about refusing to talk to people who defend Heidegger makes about as much sense as a religion telling its adherents not to listen to some specific critic. (That said, while I'm by no means an expert on this matter, my general opinion is that Heidegger is a waste of time.)

[-]shokwave14y220

It is not rational to ignore arguments because they were made by an awful person.

In academic philosophy there is a tendency to refer to "Heidegger's arguments and positions" as simply "Heidegger". (This is true of all philosophers, not just Heidegger). Popper, of course, would have been familiar with this; when I read that quote I got the distinct impression of "Heidegger's arguments are hollow and his positions are indefensible; please can we agree on this and stop discussing them?"

4Mitchell_Porter14y

Heidegger's theme from beginning to end was "Being". Why is there something rather than nothing, and what is existence anyway? In practice, it was the second question that dominated his life. He started out in phenomenology, so he was initially interested in being as appearance. We get this idea of existence from somewhere, but where exactly? How does it emerge from appearance? Another theme was the forgetting of Being in favor of beings. The modern mind, with its busyness and technological power, is usually engaged in interaction with one particular thing or another particular thing, and loses sight of the fact of existence as such. This theme led him to a historical examination of the concept of Being in different ages. A distinction between existence and essence - thatness and whatness - develops in Greek philosophy, and persists through the centuries despite many transformations, such as the emphasis on subjectivity and consciousness which characterizes the epistemology-dominated era since Descartes. By the end of his life, Heidegger considered that technology and especially "cybernetics" (computer science and information technology) were the start of a whole new epoch in humanity's relationship to Being; initially one in which the obliviousness to Being itself would persist - the metaphysical oblivion created by the focus on essence having been joined by a daily sensibility which was all about action rather than thought - but also a circumstance in which there could be a "second beginning", in which Being might be encountered anew again. So Heidegger deserves his place in the history of philosophy, and he's not obsolete yet, even if so much about him and his work belongs to a vanished culture and politics.

I once told a university friend of mine, who was majoring in modern philosophy, that Heidegger was the most empty and nonsensical philosopher I had encountered in high school. He blamed this on translation difficulties and my Marxist teacher, and offered to guide me through a selected reading of Sein und Zeit; an offer on which I took him up.

We called it quits (in a friendly manner) after five evenings of heated arguing over whether it was even intellectually permissible to use half of the words Heidegger was using, and I left with the judgment that Heidegger was raping the German language.

1Jack14y

I don't know about raping the German language but your friend is right in that a) Heideggerr, more than maybe any other philosopher ever, is harder to understand in translation and b) a Marxist might have a lot of trouble explaining Heidegger. He definitely is not an author one should take on by oneself and I definitely can't explain much of anything he's said. I do lean toward the position that he said meaningful, even important things but thats totally based on people whose rationality and intelligence I trust regarding other philosophy telling me so. His obscurity is definitely the cause of a ton of bad philosophy.

Will_Newsome pointed out the caveat that it's only good to admit errors when actually in error. I'd add a second caveat, which is that most of the benefit from admitting an error is in the lessons learnt by retracing steps and finding where they went wrong. Each error has a specific cause - a doubt not investigated, a piece of evidence given too much or too little weight, or a bias triggered. I try to make myself stronger by identifying those causes, concretely envisioning what I should have done differently, and thinking of the reference classes where the same mistake might happen in the future.

The wording actually given in this quote avoids the problems discussed by Will_Newsome and jimrandomh: admitting error clears the score, resets it to zero. If you were wrong, this wipes out your negative score, for a net win; if you were right, it wipes out your positive score, setting you back.

After finishing dinner, Sidney Morgenbesser decides to order dessert. The waitress tells him he has two choices: apple pie and blueberry pie. Sidney orders the apple pie.

Sidney chooses pies on the basis of popularity. Apple pie is more popular than blueberry pie. Apple pie is so popular that pie eaters have grown sick of it. They quickly gorge on the new cherry pie.

Its a bizarre feature of university life that it is very difficult to get students to take opportunities for help, even when they are obviously and explicitly provided.

[-]sketerpot13y170

And the reasons those students don't take opportunities for help tend to be embarrassingly pathetic. Like, so embarrassing that they avoid even thinking about it, because if they made their real reason explicit, they would be pained at how dumb it is. (I've done this sot of thing myself, more times than I'm comfortable with.)

For example, I discovered that a significant fraction of the students in a certain class were afraid to ask questions of the professor because they found him scary. Now, I know the professor in question, and he's a friendly person who wishes that his students would talk to him more -- but he has an abrupt, somewhat awkward way of speaking, and an eastern European accent. Such superficial details are apparently what leaves the biggest impression on most people.

Or there are the guys who get depressed and stop coming to class for a week or two, and then keep on not coming to class because they haven't been to class for a while, and it would be hard trying to get back up to speed. I really sympathize with these guys, but that doesn't make their reasoning any saner. (A fair number of them come in at the end of a semester to flunk their final exams. Damn it all, this... (read more)

8FiftyTwo13y

My experience of students here at [prominent UK university] is that they are very unwilling to ask for help because they have never needed to do so before, and so consider asking for help as a sign of weakness/low intelligence/low status. This makes a certain amount of sense, the people who have been able to meet entry requirements are likely in the top percentile of their subject and been the best or nearly at their school. Generally this has been the result of either natural ability or brute force work (memorising equations and examples etc) rather than acting strategically and gaining study skills such as the ability to find new sources f information or ask for help. So they either despair at the seeming impossibility of their tasks, or spend increasingly large amounts of time brute forcing the work and burn out. It takes a lot for people to understand that needing help doesn't mean you are stupid, but that the work is hard and its supposed to be hard.

4Swimmer963 (Miranda Dixon-Luinenburg) 13y

I've often found that this is so. I do try to read my textbooks, at least the assigned readings, because...well, because you're supposed to, I guess. But for most of my first year classes (three anatomy courses, psych 101, microbiology) just going to class was enough. (I did of course take detailed notes, with colourful diagrams, and then study from my notes afterwards. I have now bequeathed my anatomy notes to a friend a couple of grades younger.) One possible reason why this is true for me is that I like biology-related subjects, and I've always read anything I could get my hands on, and so I arrived in university to find that I already knew at least 50% of the material. Areas where this isn't true: English classes, history classes, etc, where there are a lot of required readings that cover material not covered in class, and where there are essays or papers to be written on material that isn't covered in class. And of course there's no rule that you can get good grades without reading textbooks. It just happens to be true sometimes, for some people.

7Desrtopa14y

There seem to be separate failure conditions here though. You could fail because you're too emotionally invested in your view, or you could fail because you can spot the flaws in all the arguments for the opposing view. If your original view was actually right, then you're not at fault. Since this can be hard to distinguish from motivated cognition, I think the exercise is questionably useful.

5Nornagest14y

I don't think the point of the exercise is to successfully defend the opposing point of view but to make a good-faith attempt to come up with an argument for it without getting your original emotions involved. If you can conjure up a coherent argument for the opposing side (allowing for a slightly different set of priors), that's some evidence that you're looking at consequences rather than being strung along by motivated cognition. If you can't -- and this is pretty common -- that's good evidence that the opposing view has been reduced to a caricature in your mind. It's a litmus test for color politics, in other words. Not a perfect one, but it doesn't have to be.

Heed a lesson from a successful practical propagandist. If you want to persuade people that a premise they unconsciously hold is wrong, do not give it a label they will perceive as insulting! If you do this, you make them reluctant to consciously accept that they hold the premise, which will make it more difficult to argue them out of it!

This rule does not hold for conscious premises. It can be effective to make insulting labels for those.

Disagree, at least in some instances. Many of these are just results of optimizing for normal environment. There is a theorem in machine learning (blanking on the name) that says any "learner" will have to be biased in some sense.

8fiddlemath14y

The No Free Lunch Theorem. Also, just because we can't expect to be free of bias doesn't mean that the bias is "proper functioning" of the hardware. An expected failure, perhaps, but still a failure.

3Dr_Manhattan14y

I make a finer distinction of "failure" as something that's inefficient for it's clear purpose. E.g. Laryngeal nerve of the giraffe. Evolution will do that on occasion. Sensory interpretations that optical illusions are based on are often optimal for the environment, and are a complement to the power of evolution if anything. Viewing something that is optimal as a failure seems like wishful thinking (though I suspect this is more of a misunderstanding of neurobiology).

2fiddlemath14y

Actually, that seems kind of fair. Something is a "failure to X" if it doesn't achieve X; something is a "failure" if it doesn't achieve some implicit goal. You can rhetorically relabel something a "failure" by changing the context. Vision works well in our usual habitat, so we should expect it to break down in some corner cases that we can construct: agreed. For me to argue further would be to argue the meaning of "failure" in this context, when I'm pretty sure I actually agree with you on all of the substance of our posts.

2Dr_Manhattan14y

I really do not want to argue about semantics either, but our agreed interpretation makes Niel's statement equivalent to "our visual system is not optimal for non-ancestral environments", which is highly uninteresting. I think the Dawkin's larengyal nerve example is much more interesting in this sense, since it points out body designs do not come from a sane Creator, at least in some instances (which is enough for his point).

I don't understand. Does that mean they have priors?

Example: There are compelling arguments that simulation hypothesis is at least somewhat likely to be correct. However, my intuition tells me that the simulation hypothesis is just plain false. I know that this is a subject that my intuition is poorly suited for, so I follow the logic and estimate a non-negligible chance of being in a simulation, despite it feeling wrong.

5gwern14y

It's an interesting topic, but what exactly makes this a rationality quote?

1Perplexed14y

Maybe it doesn't belong. But I was thinking in terms of something like rationality being an attractor. Minds, whatever their origin, if capable of self-improving, will tend toward a pattern which human economists had already identified as being at the heart of human rationality. The rational direction to guide your own improvement is toward greater rationality. Even if you are not all that rational to begin with. That means that the characteristics we assign to modeled "rational agents" may be universal - they are not just something invented by some lackey of a capitalist patron. Unless Omohundro's analysis is wrong and he just wrote it because he is a lackey, that is.

1timtyler14y

Some human irrationality seems adaptive. Humans apparently deceive themselves so they can manipulate others without actually lying - so as to avoid detection.

3Perplexed14y

That does not directly contradict Omohundro. The quotation merely suggests that almost-rational humans will seek to self-modify in the direction of becoming less self-deceptive and better at lying. A look at the self-help literature tends to confirm Omohundro's prediction. That leaves the question, though, as to why Natural Selection didn't take care of this 'improvement' itself. My guess is that it is a life-history, levels-of-selection, and kin-selection issue. Self-help books are purchased by adults. NS tries to optimize the whole life history. It is good for neither children nor their families that they become accomplished liars. Maybe self-deception in children has some advantages as well. Just speculating.

2timtyler14y

Are the liars going to win, though? Nature subsidises both transparency and lie detectors, for reasons to do with promoting cooperation. In the future it may get even harder to convince others of things you don't personally believe - as is dramatically portrayed in The Truth Machine.

I voted the comment up - because there is a relationship there. There are just other correlations and causal influences that are somewhat stronger in some situations.

-1gjm13y

The fact that you had to choose so ridiculous an example suggests that Paul Graham is basically correct. (I think the correct reading of "anything you do to decrease one will probably also decrease the other" is "if you pick something that decreases one, it will probably decrease the other" rather than "literally every single thing that might decrease one will, with high probability given that you do that particular thing, decrease the other".)

5wedrifid13y

No it doesn't. It suggests that when selecting examples for the purpose of countering generalizations wedrifid chooses examples that are clear and unambiguous to anyone who correctly parses the claim rather than choosing the most likely counter example. This is particularly the case when rejecting the extent of a general claim while accepting the gist - as I went out of the way to make explicit. I also reject the idea that the second example I gave is at all unrealistic: Corporal punishment for stupidity is an actual (hopefully mostly historical) thing.

Speaking of peculiarly boring sub-genres of science fiction, I am told that Paul Krugman was once the best and most promising of the Jedi Masters of Economics.

He has certainly become political. It might be worth asking: Has he become any less accurate in the process? Another possibility would be that the positions taken up by the major political parties in the US at present are such that it's impossible to tell the truth about some subjects without being (perceived as) highly political. (That's certainly happened often before. For extreme examples, consider cases where an important political movement is based on badly broken racial theories or on a specific religion.)

[-]Richard_Kennaway14y-30

When we exhort people to Faith as a virtue, to the settled intention of continuing to believe certain things, we are not exhorting them to fight against reason. The intention of continuing to believe is required because, though Reason is divine, human reasoners are not. When once passion takes part in the game, the human reason, unassisted by Grace, has about as much chance of retaining its hold on truths already gained as a snowflake has of retaining its consistency in the mouth of a blast furnace.

C.S. Lewis, "Religion: Reality or Substitute?", in "Christian Reflections".

2Oscar_Cunningham14y

Anyone want to try and tease a rationality message out of this?

9gwern14y

Lewis is saying that if you've disproved faith, your reason is flawed. After all, faith must be right! This is 'extraordinary claims require extraordinary evidence', but in unfamiliar garb. We're not used to seeing it used the other way. (If a study reports ESP, then we ought to suspect problems in how it was conducted or analyzed rather than accept its conclusion - to use a recent example.) I'm sure there are a number of relevant LW posts on the topic like "Einstein's Arrogance".

3Desrtopa14y

The one that immediately comes to mind for me is making your explicit reasoning trustworthy. Lewis was exhorting Christians not to trust their explicit reasoning.

5TheOtherDave14y

My take: "Because our cognition is unreliable, we can easily lose sight of truths we started out knowing as we walk along tempting-but-wrong garden paths, especially when strong emotions are involved." In other contexts this is sometimes known as "being so sharp you cut yourself."

2Nornagest14y

That's a good moral, but to me Lewis's quote seems to be more simply interpreted as an exhortation against successful doubt. Our thinking is certainly unreliable, but compensating for that with a fixed intention to keep believing whatever we're currently obsessed with seems like exactly the wrong thing to do; it essentially enshrines motivated cognition as a virtue.

2TheOtherDave14y

Having a "settled intention of continuing to believe" X shares with having a "high prior probability for" X the property that quite a lot of counterevidence can pile up before I actually start considering X unlikely. This is not a bad thing, in and of itself. Of course, if X happens to be false, it's an unfortunate condition to find myself in. But if X is true, it's a fortunate one. That just shows that it's better to believe true things than false ones, no matter how high or low your priors or settled or indecisive your intentions. Of course, if I start refusing to update on counterevidence at all, that's a problem. And I agree, it's easy to read Lewis as endorsing refusing to update on counterevidence, if only by pattern-matching to religious arguments in general.

5Nornagest14y

Point taken, but Lewis wasn't operating within a Bayesian framework. I haven't read a lot of his apologetics, but what I remember seemed to be working through the lens of informal philosophy, where a concept is accepted or rejected as a unit based on whether or not you can think of sufficiently clever responses to all the challenges you're aware of. From this perspective, a "settled intention of continuing to believe" implies putting a lot more mental effort into finding clever defenses of your beliefs, and Lewis's professed acceptance of reason implies nothing more than admitting challenges in principle. Since it's possible to rationalize pretty much anything, this strikes me as functionally equivalent to refusing to update. And, of course, enshrining the state of holding high priors as virtuous in itself carries its own problems.

2TheOtherDave14y

(nods) Mostly agreed.

2Richard_Kennaway14y

You get it.

4Normal_Anomaly14y

Within the context of Lewis' Christianity, it could be the valid form of the argument from authority: don't believe appealing falsehoods with a little evidence over unappealing truths with a lot of evidence you don't know. To give an example: you tell kids to believe evolution or special relativity without explaining the evidence in detail, but it would still be right for them to have "faith" instead of changing to believe creationism the first time they read a (bogus, but they wouldn't be able to tell) creationist argument on the internet.

5Richard_Kennaway14y

Except that Lewis' Christianity was not based on any authority deemed infallible. He reasoned himself into it, while recognising the fallibility of reason. His writings set out his arguments; they do not tout any source of authority whose reliability he has not already argued. But how can one rightly reason, while recognising one's fallibility? That is an issue for rationalists as well. Let me fix the original quote for you: When a long argument produces a conclusion that strikes one as absurd, one sometimes just has to say, "This is bullshit. I don't know what's wrong with the argument, but I'm not going along with it."

4Mass_Driver14y

I think the flaw in the syllogism is "the human reason, unassisted, has a low chance of retaining its hold on truths." We certainly forget a great deal of procedural and propositional knowledge if we don't use it on a regular basis, but that's different from letting go of a belief because you are passionate about how inconvenient the belief is. Once a belief takes root -- i.e., after you announce it to your friends and take some actions based on it -- it is usually very difficult to let go of that belief.
