In a class I taught at Berkeley, I did an experiment where I wrote a simple little program that would let people type either "f" or "d" and would predict which key they were going to push next. It's actually very easy to write a program that will make the right prediction about 70% of the time. Most people don't really know how to type randomly. They'll have too many alternations and so on. There will be all sorts of patterns, so you just have to build some sort of probabilistic model. Even a very crude one will do well. I couldn't even beat my own program, knowing exactly how it worked. I challenged people to try this and the program was getting between 70% and 80% prediction rates. Then, we found one student that the program predicted exactly 50% of the time. We asked him what his secret was and he responded that he "just used his free will."

My bet is that the student had many digits of pi memorised and just used their parity.

I would have easily won that game (and maybe made a quip about free will when asked how...). All you need is some memorized secret randomness. For example, a randomly generated password that you've memorized, but you'd have to figure out how to convert it to bits on the fly.

Personally I'd recommend going to random.org, generating a few hexadecimal bytes (which are pretty easy to convert to both bits and numbers in any desired range), memorizing them, and keeping them secret. Then you'll always be able to act unpredictably.

Well, unpredictably to a computer program. If you want to be able to be unpredictable to someone who's good at reading your next move from your face, you would need some way to not know your next move before making it. One way would be to run something like an algorithm that generates the binary expansion of pi in your head, and delaying calculating the next bit until the best moment. Of course, you wouldn't actually choose pi, but something less well-known and preferably easier to calculate. I don't know any such algorithms, and I guess if anyone knows a good one, they're not likely to share. But if it was something like a pseudorandom bitstream generator that takes a seed, it could be shared, as long as you didn't share your seed. If anyone's thought about this in more depth and is willing to share, I'm interested.

When I need this I just look at the nearest object. If the first letter is between a and m, that's a 0. If it's between n and z, that's a 1. For larger strings of random bits, take a piece of memorized text (like a song you like) and do this with the first letter of each word.

There's an easier way: look at the time.

Seconds are even? Type 'f'. Odd? Type 'd'. (Or vice-versa. Or use minutes, if you don't have to do this very often.)

A while ago there was an article (in NYTimes online, I think) about a program that could beat anyone in Rock-Paper-Scissors. That is, it would take a few iterations, and learn your pattern, and do better than chance against you.

It never got any better than chance against me, because I just used the current time as a PRNG.

Comment author: Desrtopa 12 April 2013 01:06:17AM 2 points [-]

Over 12 rounds against the veteran computer, I managed 5-4-3, just trying to play "counterintuitively" and play differently from how I expected the players whose information it aggregated would play.

Not enough repetitions to be highly confident that I could beat the computer in the long term, but I stopped because trying to be that counterintuitive is a pain.

Comment author: Roxolan 26 September 2013 04:03:59PM 1 point [-]

Got 7-6-7 with the same tactic. Apparently the computer only looks at the last 4 throws, so as long as you're playing against Veteran (where your own rounds will be lost in the noise), it should be possible for a human to learn "anti-anti-patterns" and do better than chance.

19-18-13 over 50 rounds against the veteran, without using any external RNG, by looking away and thinking of something else so that I couldn't remember the results of previous rounds. (My after-lunch drowsiness probably helped.)

That'll be almost independent but not unbiased: I think that a-m will be more frequent than n-z. However, you could do the von Neumann trick: if you have an unfair coin and want a fair sequence of bits, take the first and second flips. HT is 0, TH is 1, and if you get HH or TT, check the third and fourth flips. Etc.

Comment author: Oscar_Cunningham 12 April 2013 06:03:05PM *  7 points [-]

I just looked up the letter frequencies and it's 52% for a-m and 48% for n-z (for the initial letters of English words). Using 'l' instead of 'm' gives a 47/53 split, so 'm' is at least the best letter to use.

A remarkable aspect of your mental life is that you are rarely stumped. True, you occasionally face a question such as 17 × 24 = ? to which no answer comes immediately to mind, but these dumbfounded moments are rare. The normal state of your mind is that you have intuitive feelings and opinions about almost everything that comes your way. You like or dislike people long before you know much about them; you trust or distrust strangers without knowing why; you feel that an enterprise is bound to succeed without analyzing it. Whether you state them or not, you often have answers to questions that you do not completely understand, relying on evidence that you can neither explain nor defend.

True, you occasionally face a question such as 17 × 24 = ? to which no answer comes immediately to mind, but these dumbfounded moments are rare.

Unless you took John Leslie's advice and Ankified the multiplication table up to 25.

Comment author: AlanCrowe 04 April 2013 11:43:53AM 21 points [-]

I've read your link to John Leslie with both curiosity and bafflement.

17 x 24 is not perhaps the best example of a question for which no answer comes immediately to mind. Seventeen has the curious property that 17 x 6 = 102. (The recurring decimal 1/6 = 0.166666... hints to us that 17 x 6 = 102 is just the first of a series of near misses on a round number, 167 x 6 = 1002, 1667 x 6 = 10002, etc). So multiplying 17 by any small multiple of 6 is no harder than the two times table. In particular 17 x 24 = 17 x (6 x 4) = (17 x 6) x 4 = 102 x 4 = 408.

17 x 23 might have served better, were it not for the curious symmetry around the number 20, with 17 = 20 - 3 while 23 = 20 + 3. One is reminded of the identity (x + y)(x - y) = x^2 - y^2 which is often useful in arithmetic and tells us at once that 17 x 23 = 20 x 20 - 3 x 3 = 400 - 9 = 391.

17 x 25 has a different defect as an example, because one can hardly avoid apprehending 25 as one quarter of 100, which stimulates the observation that 17 = 16 + 1 and 16 is full of yummy fourness. 17 x 25 = (16 + 1) x 25 = (4 x 4 + 1) x 25 = 4 x 4 x 25 + 1 x 25 = 4 x 100 + 25 = 425.

17 x 26 is a better example. Nature has its little jokes. 7 x 3 = 21 therefore 17 x 13 = (1 + 7) x (1 + 3) = (1 + 1) + 7 x 3 = 2 + 21 = 221. We get the correct answer by outrageously bogus reasoning. And we are surely puzzled. Why does 21 show up in 17 x 13? Aren't larger products always messed up and nasty? (This is connected to 7 + 3 = 10). Any-one who is in on the joke will immediately say 17 x 26 = 17 x (13 x 2) = (17 x 13) x 2 = 221 x 2 = 442. But few people are.

Some people advocate cultivating a friendship with the integers. Learning the multiplication table, up to 25 times 25, by the means exemplified above, is part of what they mean by this.

Others, full of sullen resentment at the practical usefulness of arithmetic, advocate memorizing ones times tables by the grimly efficient deployment of general purpose techniques of rote memorization such as the Anki deck. But who in this second camp sees any need to go beyond ten times ten?

Does John Leslie have a foot in both camps? Does he set the twenty-five times table as the goal and also indicate rote memorization as the means?

Comment author: Jayson_Virissimo 04 April 2013 10:29:34PM *  14 points [-]

I'm not sure exactly what he had in mind, but learning the multiplication tables using Anki isn't exactly rote.

Now, this may not be the case for others, but when I see a new problem like 17 x 24, I don't just keep reading off the answer until I remember it when the note comes back around. Instead, I try to answer it using mental arithmetic, no matter how long it takes. I do this by breaking the problem into easier problems (perhaps by multiplying 17 x 20 and then adding that to 17 x 4). Sooner or later my brain will simply present the answers to the intermediate steps for me to add together and only much later do those steps fade away completely and the final answer is immediately retrievable.

Doing things this way, simply as a matter of course, you develop somewhat of a feel for how certain numbers multiply and develop a kind of "friendship with the integers." Er, at least, that's what it feels like from the inside.

Comment author: ygert 01 April 2013 07:27:50PM *  5 points [-]

That's not the important point. Even if you have, you will still face the same problem when facing a question like, for example, say 34 × 57 = ?. The quote was using that particular problem as an example. If that example does not apply to you because you Ankified the multiplication table up to 25 or for any other reason, it is trivial to find another problem that gives the desired mental response. (As I just did with the 34 × 57 problem.)

Comment author: Jayson_Virissimo 01 April 2013 10:59:43PM *  3 points [-]

Agreed. I'm not so much disagreeing with the thrust of the quote as nitpicking in order to engage in propaganda for my favorite SRS.

Comment author: Kindly 01 April 2013 09:26:57PM 0 points [-]

Of course, even if I have no complete answer to 34 × 57, I still have "intuitive feelings and opinions" about it, and so do you. For example, I know it's between 100 and 10000 just by counting the digits, and although I've just now gone and formalized this intuition, it was there before the math: if I claimed that 34 × 57 = 218508 then I'm sure most people here would call me out long before doing the calculation.

Comment author: ygert 01 April 2013 09:40:03PM 1 point [-]

What has this got to do with the original quote? The quote was claiming, truthfully or not, that when one is first presented with a certain type of problem, one is dumbfounded for a period of time. And of course the problem is solvable, and of course even without calculating it you can get a rough picture of the range the answer is in, and with a certain amount of practice one can avoid the dumbfoundedness altogether and move on to solving the problem, and that is a fine response to give to the original quote, but it has no relevance to what I was saying.

All I was saying is that it is an invalid objection to object to the quote based on the fact that with a certain technique the specific example given by the quote can be avoided, as that example could have easily been replaced by a similar example which that technique does not solve. I was talking about that specific objection I was not saying the quote is perfect, or even that it is entirely right. You may raise these other objections to it. But the specific objection that Jayson_Virissimo raised happens to be entirely invalid.

Comment author: Stabilizer 01 April 2013 07:19:22PM 33 points [-]

More specifically, one thing I learned from Terry that I was not taught in school is the importance of bad proofs. I would say "I think this is true", work on it, see that there was no nice proof, and give up. Terry would say "Here's a criterion that eliminates most of the problem. Then in what's left, here's a worse one that handles most of the detritus. One or two more epicycles. At that point it comes down to fourteen cases, and I checked them." Yuck. But we would know it was true, and we would move on. (Usually these would get cleaned up a fair bit before publication.)

At that point I'd start wondering why there doesn't appear to be a simple proof. For example, maybe some kind of generalization of the result is false and you need the complexity to "break the correspondence" with the generalization.

Right, I often play blitz games for an hour a day weeks on end and don't improve at all. Interestingly, looking at professional games, even if I don't bother to calculate many lines, seems to make me slightly better; so there are ways to improve without deliberate practice, but playing blitz doesn't happen to be one of them. Playing standard time controls does work decently well though, at least once you can recognize all the dozen or so main tactics.

Comment author: MikeDobbs 01 April 2013 11:49:11PM 4 points [-]

In my experience it can often turn out that the formulation is more difficult than the solution (particularly for an interesting/novel problem). Many times I have found that it takes a good deal of effort to accurately define the problem and clearly identify the parameters, but once that has been accomplished the solution turns out to be comparatively simple.

Comment author: PhilGoetz 05 April 2013 11:45:20PM *  3 points [-]

Hmm. Einstein is perhaps most famous for "discovering" special relativity. But he neither formulated the problem, nor found the solution (I think the Lorentz transformation was already known to be the solution), but reinterpreted the solution as being real.

His "greatest error" was introducing the cosmological constant into general relativity--curiously, making a similar error to what everyone else had made when confronted with the constancy of the speed of light, which was refusing to accept that the mathematical result described reality.

Comment author: FiftyTwo 08 April 2013 02:25:30AM 2 points [-]

Comment author: gwern 11 April 2013 03:34:09AM *  13 points [-]

My problem with this is, that like a number of Kafka's parables, the more I think about it, the less I understand it.

There is a mouse, and a mouse-trap, and a cat. The mouse is running towards the trap, he says, and the cat says that to avoid it, all he must do is change his direction and eats the mouse. What? Where did this cat come from? Is this cat chasing the mouse down the hallway? Well, if he is, then that's pretty darn awful advice, because if the cat is right behind the mouse, then turning to avoid the trap just means he's eaten by the cat, so either way he is doomed.

Actually, given Kafka's novels, so often characterized by double-binds and false dilemmas, maybe that's the point: that all choices lead to one's doom, and the cat's true observation hides the more important observation that the entire system is rigged.

('"Alas", said the voter, "at first in the primaries the options seemed so wide and so much change possible that I was glad there was an establishment candidate to turn to to moderate the others, but as time passed the Overton Window closed in and now there is the final voting booth into which I must walk and vote for the lesser of two evils." "You need only not vote", the system told the voter, and took his silence for consent.')

On the other hand, it's a perfectly optimistic little fable if you simply replace the one word "trap" with the word "cat".

"Alas", said the mouse, "the whole world is growing smaller every day. At the beginning it was so big that I was afraid, I kept running and running, and I was glad when I saw walls far away to the right and left, but these long walls have narrowed so quickly that I am in the last chamber already, and there in the corner stands the cat that I must run into."

This is much better than my moral.

Comment author: xv15 08 April 2013 05:38:53AM 4 points [-]

I will run the risk of overanalyzing: Faced with a big wide world and no initial idea of what is true or false, people naturally gravitate toward artificial constraints on what they should be allowed to believe. This reduces the feeling of crippling uncertainty and makes the task of reasoning much simpler, and since an artificial constraint can be anything, they can even paint themselves a nice rosy picture in which to live. But ultimately it restricts their ability to align their beliefs with the truth. However comforting their illusions may be at first, there comes a day of reckoning. When the false model finally collides with reality, reality wins.

The truth is that reality contains many horrors. And they are much harder to escape from a narrow corridor that cuts off most possible avenues for retreat.

If you will learn to work with the system, you can go as far as the system will support you ... By realizing you have to use the system and studying how to get the system to do your work, you learn how to adapt the system to your desires. Or you can fight it steadily, as a small undeclared war, for the whole of your life ... Very few of you have the ability to both reform the system and become a first-class scientist.

Comment author: TimS 03 April 2013 03:51:56PM 3 points [-]

I think you are using settle in its more precise meaning (i.e. release a legal claim), which is not consistent with the colloquial usage. Colloquially, "settle" is often used as the antonym of "take reasonable risks."

Similarly, I think the difference between "don't like the menu" and "fairly bad" is hairsplitting for someone who would find this level and type of advice useful. In just about any city, the BATNA is "travel to another place to eat, getting no further from your home than you were at the first place." And that's a pretty good alternative. I think the quote correctly asserts that the alternative is underrated.

But regardless of whether we believe our own positions are inviolable, it behooves us to know and understand the arguments of those who disagree. We should do this for two reasons. First, our inviolable position may be anything but. What we assume is true could be false. The only way we’ll discover this is to face up to evidence and arguments against our position. Because, as much as we may not enjoy it, discovering we’ve believed a falsehood means we’re now closer to believing the truth than we were before. And that’s something we should only ever feel gratitude for.

Within the philosophy of science, the view that new discoveries constitute a break with tradition was challenged by Polanyi, who argued that discoveries may be made by the sheer power of believing more strongly than anyone else in current theories, rather than going beyond the paradigm. For example, the theory of Brownian motion which Einstein produced in 1905, may be seen as a literal articulation of the kinetic theory of gases at the time. As Polanyi said:

Discoveries made by the surprising configuration of existing theories might in fact be likened to the feat of a Columbus whose genius lay in taking literally and as a guide to action that the earth was round, which his contemporaries held vaguely and as a mere matter for speculation.

Columbus's "genius" was using the largest estimate for the size of Eurasia and the smallest estimate for the size of the world to make the numbers say what he wanted them to. As normally happens with that sort of thing, he was dead wrong. But he got lucky and it turned out there was another continent there.

Comment author: MugaSofer 08 April 2013 07:34:12PM *  12 points [-]

Yes, actually. He believed the true dimensions of the Earth would conform to his interpretation of a particular Bible verse (thwo-thirds of the earth should be land, and one-third water, so the Ocean had to be smaller than believed) and fudged the numbers to fit.

Exactly. In fact, it was well known at the time that the Earth is round, and most educated people even knew the approximate size (which was calculated by Eratosthenes in the third century BCE). Columbus, on the other hand, used a much less accurate figure, which was off by a factor of 2.

The popular myth that Columbus was right and his contemporaries were wrong is the exact opposite of the truth.

Perhaps Columbus's "genius" was simply to take action. I've noticed this in executives and higher-ranking military officers I've met-- they get a quick view of the possibilities, then they make a decision and execute it. Sometimes it works and sometimes it doesn't, but the success rate is a lot better than for people who never take action at all.

Executives and higher ranking military officers also happen to have the power to enforce their decisions.

One test adults use is whether you still have the kid flake reflex. When you're a little kid and you're asked to do something hard, you can cry and say "I can't do it" and the adults will probably let you off. As a kid there's a magic button you can press by saying "I'm just a kid" that will get you out of most difficult situations. Whereas adults, by definition, are not allowed to flake. They still do, of course, but when they do they're ruthlessly pruned.

The way to deal with uncertainty is to analyze it into components. Most people who are reluctant to do something have about eight different reasons mixed together in their heads, and don't know themselves which are biggest. Some will be justified and some bogus, but unless you know the relative proportion of each, you don't know whether your overall uncertainty is mostly justified or mostly bogus.

Jack Sparrow: [after Will draws his sword] Put it away, son. It's not worth you getting beat again.

Will Turner: You didn't beat me. You ignored the rules of engagement. In a fair fight, I'd kill you.

Jack Sparrow: Then that's not much incentive for me to fight fair, then, is it? [Jack turns the ship, hitting Will with the boom]

Jack Sparrow: Now as long as you're just hanging there, pay attention. The only rules that really matter are these: what a man can do and what a man can't do. For instance, you can accept that your father was a pirate and a good man or you can't. But pirate is in your blood, boy, so you'll have to square with that some day.

The pirate-specific stuff is a bit extraneous, but I've always thought this scene neatly captured the virtue of cold, calculating practicality. Not that "fairness" is never important to worry about, but when you're faced with a problem, do you care more about solving it, or arguing that your situation isn't fair?

If it's a frequently-occurring observation within the group then yes, there seems to be something wrong. Possibly because things are regularly proposed and acted on without considering fairness until someone has to point it out.

Not that I don't think this is a fair counterpoint to make, but in my own experience trying to find the best arguments for religion, I learned a lot more and got better reasoning talking to random laypeople than by asking priests and theologians.

To this, the skeptics might respond: but of course we can’t win over the mainstream scientific community, since they’re all in the grip of an evil left-wing conspiracy or delusion! Now, that response is precisely where “the buck stops” for me, and further discussion becomes useless. If I’m asked which of the following two groups is more likely to be in the grip of a delusion — (a) Senate Republicans, Freeman Dyson, and a certain excitable string-theory blogger, or (b) virtually every single expert in the relevant fields, and virtually every other chemist and physicist who I’ve ever respected or heard of — well then, it comes down to a judgment call, but I’m 100% comfortable with my judgment.

I can't think of a reply to this that won't start a game of reference class tennis; but I think there's a possibility that Aaronson's list is a more complete set of the relevant experts on the climate than your list is of the relevant experts on the existence of deities.

I think "etc." is a request to the reader to be a good classifier--simply truncating the list at "etc." is overfitting, and defeats the purpose of the "etc." Contrariwise, construing "etc." to mean "everything else, everywhere" is trying to make do with fewer parameters than you actually need.

In a trivial sense I agree with you, in that there's all sorts of tribal signaling effects going on, but not if I assume honest discussion. In my experience, strongly identified Christians believe that most theologians are unreliable authorities on the nature of God.

Indeed, it would be hard for them to believe otherwise, since most theologians don't consider Jesus Christ to have been uniquely divine.

Of course, if we implicitly restrict "the theology community" to "the Christian theology community," as many Americans seem to, then you're probably right for sufficiently narrow definitions of "Christian".

If atheists really thought that theists believed just because the pastors did, then targeting the pastors would seem to be the best way to go about it, yes.

Let us say you have a paper to write but you also want to go to a party.

Or you could decide, once and for all that you are not going to go to the party, which is saying no. I think the second approach will be more effective in getting the paper done. So, I think there is actually a difference.

The lack of a well-delineated hypothesis is not necessarily a barrier to acceptance of new directions in medical practice. The classic example is John Snow's demonstration that the 1854 cholera epidemic in London was attributable to contaminants in the water. When he removed the handle from the Broad Street pump, the number of cases in the area served by that pump promptly began to wane. Exactly what was in the water that caused the cholera would not be demonstrated for more than a quarter of a century. Still the results of Snow's intervention were so dramatic that no one questioned the cause-and-effect relationship even in the absence of an explicit hypothesis. However, when the causal linkage is less obvious, the absence of a plausible hypothesis can be a significant deterrent to action.

To return to the case at hand, it was difficult for several reasons for physicians to accept the idea that the concentration of blood cholesterol could be a major factor in determining the chances of myocardial infarction decades down the road. As discussed in Chapter 3, it was not appreciated that the average blood cholesterol level in the United States, the so-called normal level, was actually abnormal. It was accelerating atherogenesis and putting a large fraction of the so-called normal population at a high risk for coronary heart diseases. Also, very little was known about the structure and metabolism of these recently discovered and still mysterious cholesterol-protein complexes -- the serum lipoproteins -- and almost nothing was known about how they got into the vessel wall and contributed to the development of the lesions. A degree of skepticism was understandable.

...What now matters most is that we avoid ending human history.

I am now sixty-seven. To bring my voyage to a happy conclusion . . . I would need to find ways of getting many people to understand what it would be for things to matter, and of getting these people to believe that certain things really do matter. I cannot hope to do these things by myself. But . . . I hope that, with art and industry, some other people will be able to do these things, thereby completing this voyage.

Joe Pyne was a confrontational talk show host and amputee, which I say for reasons that will become clear. For reasons that will never become clear, he actually thought it was a good idea to get into a zing-fight with Frank Zappa, his guest of the day. As soon as Zappa had been seated, the following exchange took place:

Pyne: I guess your long hair makes you a girl.

Zappa: I guess your wooden leg makes you a table.

Of course this would imply that Pyne is not a featherless biped.

WAYS TO KILL 2 BIRDS W/ 1 STONE

  • Radioactive stone in nest.
  • Use stone to seal off the air supply to a cage of birds.
  • Economist: Sell a precious stone (diamond? Ruby?). Use the proceeds to purchase several dozen chickens. The purchase produces an expected number of bird deaths equal to approximately the number of chickens purchased through tiny changes at the margins, making chicken farming and slaughter slightly more viable.
  • Omega: Use stone to kill the dog that would have killed the cat that will now kill 40 birds over its extended lifespan.

Most of the propositions and questions to be found in philosophical works are not false but nonsensical. Consequently we cannot give any answer to questions of this kind, but can only point out that they are nonsensical. Most of the propositions and questions of philosophers arise from our failure to understand the logic of our language. [...] And it is not surprising that the deepest problems are in fact not problems at all.

All things be ready if our minds be so.

What does this mean?

Comment author: tgb 08 April 2013 11:59:27AM 4 points [-]

In context, this is said right before the battle of Agincourt and Henry V is reminding his troops that the only thing left for them to do is to prepare their minds for the coming battle (where they are horribly outnumbered). I guess the rationality part is to remember that sometimes we must make sure to be in the right mindset to succeed.

I've always seen that whole speech as a pretty good example of reasoning from the wrong premises: Henry V makes the argument that God will decide the outcome of the battle and so if given the opportunity to have more Englishmen fighting along side them, he would choose to fight without them since then he gets more glory for winning a harder fight and if they lose then fewer will have died. Of course he doesn't take this to the logical conclusion and go out and fight alone, but I guess Shakespeare couldn't have pushed history quite that far.

A good 'dark arts' quote from that speech might be when he offers to pay anyone's fare back to England if they leave then. After that, anyone thinking of deserting will be trapped by their sunk costs into staying - but maybe that's not what Shakespeare had in mind...

Comment author: Yossarian 08 April 2013 07:19:07PM *  11 points [-]

The quote struck me as a poetic way of affirming the general importance of metacognition - a reminder that we are at the center of everything we do, and therefore investing in self improvement is an investment with a multiplier effect. I admit though this may be adding my own meaning that doesn't exist in the quote's context.

I've always seen that whole speech as a pretty good example of reasoning from the wrong premises: Henry V makes the argument that God will decide the outcome of the battle and so if given the opportunity to have more Englishmen fighting along side them, he would choose to fight without them since then he gets more glory for winning a harder fight and if they lose then fewer will have died. Of course he doesn't take this to the logical conclusion and go out and fight alone, but I guess Shakespeare couldn't have pushed history quite that far.

Rewatching Branagh's version recently, I keyed in on a different aspect. In his speech, Henry describes in detail all the glory and status the survivors of the battle will enjoy for the rest of their lives, while (of course) totally downplaying the fact that few of them can expect to collect on that reward. He's making a cost/benefit calculation for them and leaning heavily on the scale in the process.

Contrast with similar inspiring military speeches:

William Wallace says, "Fight and you may die. Run and you may live...for awhile. And dying in your beds, many years from now, would you be willin' to trade ALL the days, from this day to that, for one chance, just one chance, to come back here and tell our enemies that they may take our lives, but they'll never take our freedom!" He's saying essentially the same thing as Henry, but framing it as a loss instead of a gain. Where Henry tells his soldiers what they'll gain from fighting, Wallace tells them what they'll lose if they don't. Perhaps it's telling that, unlike Henry, he doesn't get very specific. It might've been an opportunity for someone in the ranks to run a thought experiment, "What specific aspects of my life will be measurably different if we have 'freedom' versus if we don't have 'freedom'? What exactly AM I trading ALL the days for? And if I magically had that thing without the cost of potentially dying, what would my preferences be then?" Or to just notice their confusion and be able to recognize they were being loss averse and without the ability to define exactly what they were averse to losing.

Meanwhile, Maximus tells his troops, "What you do in life echoes in eternity." He's more honest and direct about the probability that you're going to die, but also reminds you that the cost/benefit analysis extends beyond your own life, the implication being that your 'honor' (reputation) affects your placement in the afterlife and (probably of more consequence) the well being of your family after your death. Life is an iterated game and sometimes you have to defect (or cooperate?) so that your children get to play at all.

And lastly, Patton says, "No bastard ever won a war by dying for his country. He won it by making the other poor, dumb bastard die for his." He explicitly rejects the entire 'die for your country' framing and foists it wholly onto the enemy. It's his version of "The enemy's gate is down." He's not telling you you're not going to die, but at least he's not trying to convince you that your death is somehow a good or necessary thing.

When taken in this company, Henry actually comes across more like a villain. Of all of them, he's appealing to their desire to achieve rational interests in an irrational way without being at all upfront about their odds of actually getting what he's promising them.

Most of quantum physics and relativity are certainly intuitively weirder than Jesus turning water into wine, self-replicating bread or a body of water splitting itself to create a passage.

I mean, our physics say it's technically possible to make machines that do all of this. Without magic. Using energy collected in space and sent to Earth using beams of light. Although we probably wouldn't use beams of light because that's inefficient.

Well, I dunno, if you describe physics as a Turing machine program, ala Solomonoff induction, special relativity may well be more incredible than god(s), chiefly because Turing machines may well be unable to do exact Lorentz invariance, but can do some kind of god(s), i.e. superintelligences. (Approximate relativity is doable, though).

These studies are the record of a failure-- the failure of facts to sustain a preconceived theory. The facts assembled, however, seemed worthy of further examination. If they would not prove what we had hoped to have them prove, it seemed desirable to turn them loose and to follow them to whatever end they might lead.
