Some inconvenient truths (well, "facts") from the quotes in the latest slatestarcodex post (see the sidebar):

The most reliable way to create a lasting community is basing it on shared religion AND costly personal sacrifices. Secularity doesn't cut it, even if demanding sacrifices.
Being religious signals trustworthiness: "The highest levels of wealth ...[is]... created when religious people get to play a trust game with other religious people."
" religion in the United States nowadays generates such vast surpluses of social capital that much of it spills over and benefits outsiders."
Liberals are the least accurate in modeling the views of other political groups (moderates and conservatives).

Note that this is all based exclusively on the US data.

The most reliable way to create a lasting community is basing it on shared religion AND costly personal sacrifices. Secularity doesn't cut it, even if demanding sacrifices.

What kind of secular communities was used in the research? The "secular community" without further specification feels a bit like a non-apple.

Maybe this is because religious communities try to solve all aspects of their member's lives, while secular communities usually have a single purpose. Single-purpose communities can fall apart when their members focus on some other asp... (read more)

Cialdini's Influence presents a pretty strong case for Sacrifice being a very powerful method for ensuring group cohesion all by itself. For example, Fraternities and Hazing or indigenous peoples and coming-of-age rituals. The first reason I would think of that religion does a good job of holding groups together is that it's an interest that you're "not supposed to" grow out of, unlike things like drinking/partying and playing sports.

0pianoforte61111y

Strong communities tend to have a shared religion but this doesn't tell us which way the casual arrow points. Given that trustingness is heritable, I think its likely that trustingness increases both religiosity and the ability to form a community. The sacrifice result seems a bit more robust since it was done with both religious and secular groups. About liberals, they are the least accurate in modeling how other political groups describe themselves. However, this could mean that other groups are less genuine in their self description: for example conservatives that think that gays are gross will probably appeal to "family values" rather than being honest. And really all this tells us is that other groups are harder to understand. This doesn't tell us if they are right or not.

Here's an interesting application of elementary probability theory.

Syria recently held an election, in the midst of a civil war. Dr. Bashar Hafez al-Assad wins post of President of Syria with sweeping majority of votes at 88.7%.

The elections were a sham. The vote counts are completely fraudulent. And you can learn this just from the results page linked above, without knowing anything about Syria or its internal politics. How?

The results are too accurate.

"11,634,412 valid ballots, Assad wins with 10,319,723 votes at 88.7%". That's not 88.7%, that's 88.699996%. Or in other words, that's 88.7% of 11,634,412, which is 10,319,723.444, rounded to a whole person.

The same is true about all other percentages in this election. In one of the results there's even a bad rounding error: 4.3% cast for Al-Nouri is 11,634,412 * 0.043 = 500,279.716 votes which is rounded down to 500,279 votes in the results instead of the closer 500,280. As a result, the total number of all alternatives (three candidates + incorrect ballots) differs from the total number of valid ballots by 1 (442,108 + 10,319,723 + 500,279 + 372,301 = 11,634,411 and not 11,634,412. If they were rounding correctly, their f... (read more)

[-]whales11y250

I have no idea how likely it is, but an alternative explanation is that the vote counts were first converted to percentages to one decimal place, then someone else converted them back to absolute numbers for this announcement.

9Nornagest11y

Nice work. I tend to take high-profile election results over 66% or so in favor of one option as prima facie evidence of election fraud (maybe 75 if there's some exceptionally strong reason to vote one way or another, like if one of the candidates is dead), but this is certainly damning. You'd think that the perpetrators of electoral fraud would realize this sort of thing -- but I suppose the most likely explanation is that (dons Robin Hanson glasses) elections in these cases aren't about legitimacy, but rather about proving that one party has enough power to enforce a clearly illegitimate result.

[-]Daniel_Burfoot11y120

I am thinking about forming a non-profit organization called "Thalassocracy Now". The sole purpose of this organization will be to convince the Singaporeans to set up a confederation of coastal charter cities in various impoverished places bordering the Indian and South Pacific oceans (east Africa, India, the Persian Gulf, southeast Asia, etc). The cities will be ruled by the draconian but honest and efficient Singaporean government. They will be linked together by trade routes, naval and air power, and a common legal and administrative framework. The inhabitants of the cities will have some minor influence over their own city's government, but no broader political power; the basic bargain will be: if you don't like it here, leave.

Okay, just kidding, I am not actually planning to do this. But I think someone should.

9James_Miller11y

I remember reading in Lee Kuan Yew's autobiography that China asked him to set up a Singapore in China, but Lee said this wouldn't be possible. More practically, let's get a copy of Lee's DNA and when the technology becomes available make a few thousand clones of him that in 20 years can be made mayors of major cities.

The Gulf is impoverished? Besides, isn't Dubai just a better version of Singapore?

1Daniel_Burfoot11y

I was thinking of Yemen, Oman and Somalia, though now that I look at a map I see they're not technically on the Persian Gulf. I've heard good things about Dubai, but not enough to do a serious comparison between it and other countries. Ideally, Dubai and Singapore would both set up thalassocracies, competing in a friendly way for trade and citizens. Their cities could be adjacent to one another, kind of like Burger King and McDonalds.

4Salemicus11y

Interestingly, one of your proposed colonial sites, Oman, already followed your plan, several centuries ago. They set up thalassocracies all down the coast of East Africa, and even moved their capital to Zanzibar, out-competing the incumbent Dutch and Portuguese thalassocracies. Those cities were indeed linked by trade routes, naval (but not air) power, and a common legal and administrative framework. Consider the career of Ibn Battuta, or indeed the entire Hadramawt. What's to stop your proposed thalassocracies being displaced in exactly the same way, by other, less capitalist, imperialists, or by violent nativist sentiment?

2komponisto11y

(To do so would be a category error, because Dubai is in fact a city -- and, unlike Singapore, not an independent one. The country it's in is called the United Arab Emirates.)

0lmm11y

As your own link says, Dubai is something equivalent to a principality. It seems to empirically cluster closer to Singapore than to, I don't know, Istanbul.

3komponisto11y

You seem to be missing the point, which is about its political subordination to a larger entity. What I was attempting to correct was (possible) ignorance of the existence of the UAE. Here are the first two sentences of my link (emphasis added): For all that an "emirate" may be similar to a "principality" (or, dare I say, a "count-y"), the fact remains that the political status of Dubai is different from that of e.g. the principality of Monaco, in the sense that Monaco is an independent country, and Dubai isn't. Dimensions along which Dubai is more similar to Singapore than Istanbul aren't relevant to this point. (If someone pointed out that California was part of the United States, you wouldn't argue with them by saying that it's the seventh largest economy in the world [or whatever] and therefore "empirically clusters" with countries rather than states.)

2lmm11y

In some legalistic sense Monaco may be more independent than Dubai. But in practical terms like "how different are its laws from France/UAE" I'd say it's the opposite. My point about empirical differences wasn't about economy, it's that Dubai is much more like a sovereign city than like an ordinary city in a country, even in purely governmental terms like taxes and courts and so on.

3komponisto11y

Let's pause for a moment for a meta-level reflection. You're engaging in metacontrarianism, with the relevant uneducated/contrarian/metacontrarian triad being: Dubai is a country / No, Dubai is part of the UAE / Dubai has a lot of power and autonomy within the UAE. The trouble with metacontrarianism is that metacontrarians often seem to forget that even if they're right -- that is, even if the third level of the triad is true -- the first level is still wrong. In some sense, you have to pass through the second level in order to legitimately claim the mantle of the third. (Here, "pass through the second level" means not "go through a stage of being at the second level" so much as "understand why, and in particular that, the second level is an improvement over the first".) I submit to you that if Alice thinks Dubai is a country because she's never heard of the UAE, and Bob thinks that Dubai is the UAE's version of Istanbul, Bob's model of the political geography of the Arabian peninsula is still better than Alice's, even if Carol, who thinks that Dubai is so different from the rest of the UAE that it "might as well" be a country in its own right, has a better model than Bob. Now, to return to the object level, I don't actually see why Carol's model is better than Bob's. I don't know that much about the internal politics of Turkey, but I assume that Istanbul, being a major city, is culturally and demographically different from most of the rest of the country, wields a lot of influence in the country's politics, and has governmental policies that most other parts of the country don't have. For that matter, the same is true of New York City, whether regarded as a part of New York State or of the United States. In neither of these cases do I see any need to give up the model that has these cities being politically subordinate to the nation-states (or states) that contain them, and I don't see how the case of Dubai within the UAE is any different (or, anyway, different

1Richard_Kennaway11y

At this point in a discussion one would have to dissolve the word "country" and ask what properties of Dubai are important to the discussion. A glance at a few Wikipedia articles indicates that the UAE is a federation of kingdoms, in which all powers not explicitly granted to the federation are retained by the members, each of which has absolute sovereignty within its borders under a hereditary king. Before the UAE was created, the emirates were absolute sovereign entities (i.e. "countries"). After it was created what were they? Well, "are" the members of the EU "countries"? Yes. "Are" the states of the US? No. "Is" Dubai? Doesn't matter, look instead at the question of substance, which was: Dubai might want to first informally square things with the other members of the UAE (or at least, the one other member that matters, Abu Dhabi), but establishing overseas colonies, er, charter cities, would not necessarily be an activity that would officially concern the UAE federal entity.

0komponisto11y

I never intended to enter the discussion in the first place; my original comment was parenthetical. I was simply pointing out a verifiable, objective, yet quite possibly tangential matter of fact that some participants (or readers) may have been unaware of. Whether Dubai is a country or a part of a country is not a question that there's any ambiguity about. It's not a subject of dispute, as in the case of e.g. Taiwan. It's a simple matter of looking the answer up in Wikipedia. If you want to question the answer you find there, fine, but then you have to question the notion of "country" in general, and acknowledge that you're doing so, otherwise you're not being intellectually honest.

0lmm11y

I'm not trying to be metacontrarian. I disagree with this point. I think Bob's model is less good than Alice's in that it will make less accurate predictions of empirical facts (and potentially dangerous ones, given that e.g. alcohol is legal in some but not all of the emirates).

4komponisto11y

Forgive me, but this is preposterous. Neither model makes predictions about policy differences among the emirates, except insofar as Alice's model predicts that the other emirates don't exist. Different parts of a single country can have different policies, on alcohol or anything else, and do all the time. U.S. states have all kinds of differing laws. In California it's illegal to have a pet gerbil; in other states it isn't. You wouldn't for one moment cite this as an argument that California is a country. Or would you? On the other hand, here is an empirical question where the models do in fact differ: Alice's model predicts that Dubai is a member of the UN and that the UAE (being nonexistent) isn't, while Bob's model predicts that the UAE is a member and that Dubai (being part of the UAE) isn't. Which model's prediction is more accurate? Or how about this: which entity has embassies in other countries? Also an empirical fact. Which model predicts it correctly? I suspect you know the answer as well as I do. I therefore don't believe you when you say

1lmm11y

Whether we ultimately consider California a country or not is just an argument about the meaning of words (and the practical answer is that we have the word "state", which usually means a country but also means California). But I'd certainly say that the US is a very noncentral example of a country, and I'd warn people travelling there that the states of the US have some of the properties of countries and therefore it's important to e.g. check state laws in a way that you wouldn't do for subdivisions of more typical countries. Well of course the model that contains the correct the international-law technicalities is the model you'd want to use if you wanted to predict international-law technicalities. Just like if you want to predict where to find a tomato in a biology textbook, you should model it as a fruit. But if you want to know what to cook with it, you're better off modelling it as a vegetable.

4komponisto11y

However, that doesn't mean it doesn't have an answer. The stopsign "that's just an argument about the meaning of words" is useful in cases where a genuine ambiguity about the meaning of a word has caused a discussion to be diverted from its main topic, which was something else. But here, the meaning of words is the topic (as I noted in my reply to RichardKennaway, I entered this thread exclusively to point out the official political status of Dubai), and there's no ambiguity about what the answer is. Indeed, there's not even any argument. Rather, what we have is me pointing out a certain fact, and you (and others) evidently seeking to justify ignorance of that fact. To the extent there is any argument, it's about how important the fact is, not about whether the fact is true. The answers to semantic questions, when they exist, may not be ultimate or necessary or fundamental or even important, but they are still real. Well, I suppose that depends on your point of view. For me, the US is the central example of a country, because it's the one I live in and am a citizen of. I would in fact be curious to know what your idea of a "central" country is. One that's smaller? Okay, but smaller countries still have political subdivisions (as indeed, do U.S. states themselves), and the whole point of political subdivisions is that policies may differ among them. France has a lot more centralization of policy than the US does, but I'll still bet you that the municipal code of Paris is non-identical to the municipal code of Marseille. Spain's "autonomous communities" definitely have differing laws from each other: Catalonia, for example, has banned bullfighting, which would be unthinkable in other parts of the country. Do you doubt that one could multiply such examples at will? "International-law technicalities" include things like what embassy you have to go to to get a visa to travel to the place. I dispute your implicit marginalization of these "technicalities", just as I wou

-1lmm11y

Language is a tool for communication. Daniel_Burfoot's original post was clear (and "compare Dubai with other cities" would have been misleading); while a formulation like "compare Dubai with other zones where a particular legal and administrative system applies" might be technically more correct, I don't think the difference justifies the verbosity. I think we could form a reasonably uncontroversial ranking of countries by "how distinct their political subdivisions are", and the US would be close to one end of the scale (though not quite as far along as UAE). Do you disagree? A typical country has some minor variations within the country (though perhaps not if we restrict ourselves to law rather than administrative codes), sure. But I think the scale of variation seen in the US is very much atypical.

1komponisto11y

Here is more of the context: In the above, "the UAE" should replace "Dubai". If the UAE is so heterogeneous a country that greater specificity is required, then it should read "the UAE (particularly Dubai)", just as someone might write "the USA (particularly New York)". The set {Yemen, Oman, Somalia, Dubai} is "wrong", for the same reason that {plane, train, boat, driver's-seat-of-car} is; they should be respectively "corrected" to {Yemen, Oman, Somalia, UAE} and {plane, train, boat, car}. Mildly, but that disagreement is tangential. Even if the UAE has the most distinct political subdivisions of any country in the world, it is still a country, and its political subdivisions are still political subdivisions. The distinction between a country and a non-country is pretty sharp as far as human societal constructs go. We have established institutions for adjudicating this question (such as the UN, international treaties, diplomatic relations, etc.), and the results they present on the specific case of Dubai vs. the UAE are pretty unambiguous. I doubt it is, when adjusted for size (of both territory and population). I must admit that your model of a typical country seems very strange to me. It seems to correspond not even to (my model of) a US state, but to a smaller subdivision like a county or municipality. (That's the level on which you find differing policies about alcohol, for instance.)

-2lmm11y

Again, I disagree; it's a useful set for practical purposes, in the same way as {lettuce, cucumber, tomato}. Again, very much a US peculiarity. A quick look suggests India and UAE are the only other countries where alcohol is banned in some regions but not others, as opposed to over a dozen countries with national bans.

3komponisto10y

To be explicit about something I wasn't explicit about in my other reply: There is an ambiguity here, but if what you are claiming to disagree with is the analogy to {plane, train, boat, driver's-seat-of-car} (as opposed to merely the "wrongness" of either), then you genuinely do not have a good understanding of, or are stubbornly refusing to acknowledge, the relevant political geography, and I would suspect you of having heard of Dubai before you had heard of the UAE (probably as a result of journalists' ignorance), and anchoring on this fact. But I can't be sure to what extent we really have differing models of how the world works, as opposed to at least one of us going out of our way to signal something (willingness to disregard official politics in your case, familiarity with the Middle East in mine).

-3Eugine_Nier10y

If your goal was to signal your familiarity with the Middle East, you've utterly failed since it appears you didn't know how the UAE was organized. You come across as one of those people who memorizes lists of countries and capitals and possibly shapes but has no idea how the map does (or does not) correspond to facts on the ground.

2komponisto11y

I am having a hard time understanding your motivation for vigorously defending ignorance of the UAE's existence from my attempt to correct it. As far as I can tell, you're worried that someone who thought Dubai was a country and knew that alcohol was legal there might, upon learning the indisputably true fact that Dubai is inside a country called the UAE, conclude that alcohol was legal in the rest of the UAE also -- apparently on the assumption that products cannot be banned at any lower level of government than the national, in any country in the world. But anyone who makes such an assumption is likely to be suffering from a model of governance too fundamentally broken for this discussion to even matter to them. Furthermore, it's hard to imagine how a situation where someone practically benefited from ignorance of the UAE's existence would even arise. After all, it would be unlikely for a foreigner to end up in Dubai without learning about the UAE in the very process of getting there. (If, as a result of this discovery, they hatched a plan to take alcohol from Dubai to some other emirate where it wasn't legal, perhaps they would have been better off not knowing that the latter was in the same country; but it would be too late.) Given this, I really don't understand what the harm is in educating people about the existence of the UAE in a context like this, a discussion of hypothetical geopolitics on a sophisticated website. I didn't even claim the fact was terribly important; the parentheses in my original comment were intended to be the functional equivalent of labeling the comment a "nitpick". I do think that it is the kind of fact that readers of this site ought to know, if they don't already. It's not as if the cost of learning it were high. This is once again tangential, but what matters here is not whether policy contingently happens to be uniform throughout a country (because all localities agree on the correct policy), but whether the uniformity necessari

Belgium is more subordinate to the EU than Dubai is to the UAE.

So what? Dubai is still more subordinate to the UAE than you would have thought if you didn't know the UAE existed.

-1Douglas_Knight11y

If you follow your definition, rather than intellectually dishonestly changing definitions in every comment, you should stop calling Belgium a country. Or start calling Dubai one. If your point is merely to point out the existence of UAE and its small effect on the relative country-ness of Dubai, your original statement should not have been absolute. You appear to be using as your definition of country "member of the UN." If you want a canonical list of countries, that's about all you can do. But I don't trust authority to list countries just as I don't trust authority to list poisons.

2komponisto11y

We differ on that point, then. The concept of "country" as I intend it here is more or less entirely a matter of what authorities list (in contrast to the concept of "poison", which involves the question of whether something kills you). The authorities here aren't epistemic ones pointing to empirical facts, but are rather political ones making declarations that they intend to enforce. "Member of the UN" is at least a sufficient condition for countryhood, and the sense of my original comment is approximately the same as if it read:

0Lumifer11y

Well, in practical terms "setting up" a thalassocracy in such places would have to start with landing a pretty sizeable army on the shore and fighting it out with the locals. Kinda like the US experience in Afghanistan (and the Russian experience there before, and the British experience there before that...). "Nation-building" in the Middle East and environs has been a pretty miserable failure so far.

2Daniel_Burfoot11y

To be clear, I am definitely not advocating large scale military invasion and occupation. The external power would take over a tiny bit of land - say 1000 km2 - to set up a city. Let's do a quick comparison between Yemen and Singapore: * Land area (Km2): Yemen 5e5, Singapore 7e2 * Population: Yemen 2.4e7, Singapore 5.4e6 * Population density (person/km2): Yemen 4.4e1, Singapore 7.5e3 * GDP (nominal $) : Yemen 3.6e10, Singapore 3.3e11 The point is that Singaporean institutions are vastly more efficient at turning land area (an intrinsically scarce commodity) into liveable and economically viable polity. One way to formulate the goal of political development is to attempt to maximize the number of people living under good, efficient, non-corrupt governments. The thalassocracy concept is a way of implementing that goal without major political upheaval (e.g. revolution, war, massive immigration, etc).

2Lumifer11y

So, a small-scale military invasion and occupation?? The issue isn't land you will be taking over, the issue is people. Some of them (probably a lot) will not want your thalassocracy. Some of them (and in Yemen, pretty much all of them) will be adept with weapons. You want to come into the Middle East, set up an enclave completely different (politically, culturally, etc.) from anything around it and you don't expect war? Um, may I suggest you ask the Israelis about how well it works X-/

-3Eugine_Nier11y

The difference is that the US attempted to establish democracy, i.e., hand over power to the locals as quickly as possible, I believe Daniel's plan would avoid this. The problem both the Russians and British had was interference by rival powers, the US and Russia respectively. The Russians also had the problem that the economic system they wanted to impose being dysfunctional.

2Lumifer11y

I don't think it mattered what the US attempted to establish and, actually, I don't think it tried any such thing anyway. In any case, you seem to be arguing for old-style colonialism based on crushing military superiority. Even leaving aside whether it will work in our times, I am pretty sure that's not what OP has in mind.

0Eugine_Nier11y

They held elections and put the people who got majority into positions of power. Old-style colonialism wasn't based on crushing military superiority, during the British Raj the number of British born troops in India was a tiny fraction the the native troops. Thus the British relied on the cooperation of large numbers of Indians and Indian troops. What do you mean by this? Are you saying that the laws of nature somehow changed over the past century?

2Lumifer11y

Elections are no big deal. Mugabe holds elections, Putin holds elections, hey, even Assad recently held elections. Yes, it was. Certainly, it wasn't just military superiority, especially once the colonies were established, and the British, for example, became masters of control through political and financial means as well. However the military strength was the underlying bedrock. Which particular laws of nature do you have in mind?

-1Eugine_Nier11y

Well, the US forces actually attempted not to rig them. Disagree. Military strength was based on a bedrock of competent management. Whichever laws you invoked when you said implied that "old-style colonialism won't work in our time" is a reasonable hypothesis.

2Lumifer11y

No need to, the locals can do everything necessary. The US forces just provided the money and prevented the "undesirables" from playing. I did not invoke any laws of nature. I think that in the current social, political, informational, military, etc. global environment the old-style colonialism is highly unlikely to work. No laws of nature are involved in this assertion.

Loving the forename, forename, BOSTROM, forename, forename!

9Nornagest11y

The odd thing about that graph, to me, is the large number of estimates in the middle of the scale for P(simulation). I'd have expected more people to accept the simulation argument (and rate it very high) or reject it outright (and rate it very low). I guess we might be seeing uncertainty over whether or not to accept the argument, or some kind of computationally bounded simulation argument where the root universe can only handle a relatively small number of simulations. I don't quite think I buy the latter, though.

7KnaveOfAllTrades11y

I sure know that in my brief considerations of the matter, the paths of thought have consisted of a lot of 'Well if this is true, then that is almost certainly true' and lots of meta- and meta-meta-uncertainty. E.g. 'Well, if X and Y (meta)epistemological/(meta)metaphysical propositions hold, then it seems like P(Simulation) is zero/is a half/is one. But I'm not sure if I'm overlooking some class of cases that weaken the implication, so maybe it merely seems like P(Simulation) is that high under those propositions, but actually it's not'. That immediately leads to lots of cases arising as X, Y, and 'seems like' are variously true or false or not applicable. So it wouldn't surprise me at all if uncertainty over arguments gave rise to the middling estimates. I also wouldn't buy the latter. It wouldn't have occurred to me as an explanation. Given he's the expert on the simulation argument, I was pretty disappointed that there wasn't an estimate by BOSTROM for it.

I frequently see parents stressing out and forcing their kids (3+) to eat or eat enough, when the kids don't want to eat. So which one is it? Do kids really lack the capacity start eating before it becomes unhealthy and need to be coerced.... or are parents doing something irrational?

5polymathwannabe11y

Before the Industrial Revolution, people ate when they were hungry. Our insistence on meals at fixed times is a modern effect of accurate watchmaking and the introduction of work shifts.

[-]Nornagest11y100

That seems... less than obvious to me. One could as easily say that modern food-preservation technology (refrigeration, sealed containers, chemical preservatives) enabled snacking, and that preindustrial people would have had a stronger incentive to eat preplanned meals. That's a just-so story, granted, but most of the preindustrial cooking methods I'm familiar with would have taken hours and produced food for many people: not exactly conducive to eating individually as a response to hunger.

Of course, eating at precisely 7:00 or whatever is enabled by modern timekeeping, but my understanding is that the concept of a noon or an evening meal has been around for a long while. (Breakfast in the modern sense is more recent, though.)

5kalium11y

Perpetual stew

9Nornagest11y

Click through to the page on medieval diet and it presents a two-meal structure based on grains and alcohol, with the main meal around noon and a lighter one in the evening. Which is about what I'd have thought. Also some interesting moralism around meal timing. Though it does say that snacking was common (if disapproved-of by the church), so I guess my wild-assed guess there was wrong.

5kalium11y

My point was that the technology of the time did not prevent snacking on prepared food. Not that people actually did so. Probably should have actually said that instead of just giving a bare link.

4Lumifer11y

I suspect that there was/is a big difference between foragers and farmers in that respect. Snacking also doesn't require modern food-preservation technology. It's easy to snack on apples, berries, bread, cheese, etc.

1A1987dM11y

Which unfortunately means that even refraining from buying junk food doesn't completely stop me from eating before dinner! :-(

6Viliam_Bur11y

I mostly agree with you, but let's not take this "reversing stupidity" too far. Centuries ago, many people died in their child years, so this is not as strong evidence as it would be in a hypothetical universe where people ate when they were hungry and all children survived. I mean, maybe with 90% of children, letting them wait until they are hungry would be okay, but with 10% it would be harmful. Such hypothesis can only be proved or disproved by someone with detailed knowledge, not by simple comparison with eating habit of our ancestors.

5NancyLebovitz11y

It may also be a matter of convenience for the parents-- if you let the child stop eating when they feel like it, they might be hungry in a half an hour, when you were hoping to do something else. I'd want to see some cross-cultural work on how much parents control the amount small children eat.

6Viliam_Bur11y

What kind of secular communities was used in the research? The "secular community" without further specification feels a bit like a non-apple. Maybe this is because religious communities try to solve all aspects of their member's lives, while secular communities usually have a single purpose. Single-purpose communities can fall apart when their members focus on some other aspect of their lives. For example, yesterday they wanted to save the whales or start the proletarian revolution, today they want to start a family. A religious community can satisfy a wider range of needs. Also, your relatives are often part of the same religious community. I imagine this is because religion has a clearly defined set of rules, and members are punished by other members if they break them. I can imagine that a christian who would steal from many people, would be unpopular within their own community. On the other hand, when a social justice warrior would steal from many people, their victims would be probably told to check their privilege, and called sexist / racist / ...phobic for trying to avoid them. Okay, I exaggerate a bit here to illustrate the point. Being a member of a group is an evidence of a trait if the group tries to change or avoid people who lack the trait.

4Douglas_Knight11y

What kind of secular communities? This question is answered in the linked post. The answer, for both secular and religious is: nineteenth century American communes. The paper is here.

3Lumifer11y

Not quite -- for a counterexample consider whether being a highly religious Muslim signals trustworthiness in the contemporary US. I think in local terminology this can be generalized as an observation that high-cost precommitment to avoid certain behavior provides a convincing signal :-) Looking at the whole thing from 10,000 feet I am impressed by how much the high-trust societies are more productive than low-trust societies.

3pianoforte61111y

This is a good point, being a member of the dominant religion signals trustworthiness, and most Americans probably assume religious means Christian.

9Lumifer11y

I think being a member of the same religion as you signals trustworthiness. The position of Orthodox Jews in the diamond industry was quoted as an example -- Judaism isn't a dominant religion (in Amsterdam and New York), but Orthodox Jews trust *each other*.

0Lumifer11y

Why would being a highly religious Muslim make you a popular business partner?

0lmm11y

Because it would indicate that you are a person of strong integrity, whose moral convictions mean a lot to you, and thus someone to be trusted.

0Lumifer11y

Interesting. So do you, then, buy into the popular perception of atheists as people without moral convictions and lacking integrity? There is also the empirical reality of a lot of visibly highly religious people turning out to have serious problems with integrity and honesty. And, of course, being really religious means the subordination of the mundane life to the pursuit of religious goals. You can trust such a person to be who he is, but you may be mistaken about the ranking of his values :-/

0lmm11y

It's more that I'd think of non-practicing religious or "spiritual but not religious" folks as that. Serious, committed atheists, those who sacrifice popularity, time and money for the sake of their atheism, I would accord the same trust (and for the same reasons) as the committed Muslims.

6Viliam_Bur11y

Once there was a confusion about what "liberal" really means, so some people decided to call themselves libertarians instead. Now there is a confusion about what "libertarian" really means. Seems to me we have some kind of ideology-name treadmill here, which works like this: * start a political movement * become popular * many people will use the name of your movement, even if they disagree with a few (or later: many) points * at some moment those people will complain that you want the definition to include you, when you are obviously merely a fringe member of this movement

2pragmatist11y

And it's not even universal in the US. Or at least, it wasn't at some point. Noam Chomsky has often referred to himself as a libertarian, and he is certainly not a right-libertarian. Glenn Greenwald is also sometimes called a libertarian, and he doesn't have right-wing economic views either.

Sometimes I come up with scenarios where nothing seems to be wrong yet something still bugs me.

Say there is an economy of two people, Alice and Bob. Bob has an object, say a monthly newspaper, that he personally values at $5. Alice values the newspaper at $7 and thus they are willing to exchange the object at some price strictly between $5 and $7. Now Charlie, who values the newspaper at $10, comes along and is willing to bid a higher monetary amount than Alice, taking her opportunity to make an economic surplus of less than $2.

9David_Gerard11y

Try to find actual examples. See if you can find two examples where your intuition as to which way is correct are different.

6Lumifer11y

Why is this a problem? The mere presence of a bunch of people who are trying to use the road at the same time as I do hurts me. That doesn't mean I have a claim against them. Or just look at any markets. The general rule is that for Alice to assert a claim against Charlie, Charlie must have some sort of legally recognized duty towards Alice. Just showing loss is not sufficient.

4Slider11y

I guess that you would also find it equally vexing if Daisy comes with a newspaper and newspaper valuation of $3 and "damages" Bob by trading with Alice. Also note that if Bob has two newspapers he just sells to both Alice and Charlie. Is it now Charlie that complains about 3$ of damages or Alice that doesn't get the newspaper because Charlie sets a price over 7$ while there would have been enough newspapers to go around? (I guess Bob could also complain if he only gets 2*$7 while the average valuation would have been higher). Suspecting that there is a "trade is good" or "trade is fair" assumption for certain sense of "good" and "fair" that just doesn't hold. Most likely you are treating market value as property. The value is not in the object to be traded but also in the needs of the peoples using it.

3wadavis11y

This is a big issue, the root of protectionism vs. free trade. My first example is the National Energy Program from the 1970s to 1980s in Canada. Left Canada (Alice) legislated the prices Right Canada (Bob) could sell their oil to Alice while the World (Charlie) was offering higher prices. The second example is a little more convoluted but have a look at the Canada–United States softwood lumber dispute. In this case Bob and Alice are producing newspapers for $5 and $7 respectively. Charlie is a newspaper distributer wants to protect Alice who is his sister, so he charges the buyers an extra $2 for Bob's papers to keep things fair. Edited for spelling.

2Slider11y

Don't you mean free trade? Fair trade is about ensuring a non-poverty compensation to workers in poor production countries which wouln't be that opposed to protectionism.

2Punoxysm11y

Yep, absolutely Alice is injured. In many market scenarios this is true. Usually, of course, Alice is both a producer and a consumer so broad protectionist laws will hurt her. But sometimes, the "pure buyer" idea is true. So, for instance, incumbent renters have a strong incentive to advocate rent control; otherwise, a frothy real estate market will force them to find new housing.

Regular reminder that, yes, there really have been some pretty smart philosophers in previous eras: http://en.wikipedia.org/wiki/Ramsey%E2%80%93Lewis_method

Frank P. Ramsey seems to be generally regarded as a prodigy. But I have a vague impression that Lewis has a mixed reputation and some even think he's outright crap. But everything of his I've seen mentioned seems at worst merely plausible and important to consider, and at best maybe decades ahead of its time. Does anyone know why he might have a bad reputation with some?

[-]pragmatist11y160

David Lewis is generally regarded as one of the most formidable philosophers of the last century in terms of sheer intellectual firepower. I'm not aware of anyone who thinks he's outright crap. His papers are incredibly well-written - dense, but very well argued and lucid. On topics of interest to LW: he made significant contributions to causal decision theory, the interpretation of probability, the compatibilist account of free will, physicalism about the mind, and the counterfactual analysis of causation.

However, he has been criticized for too often directing his impressive abilities towards an ill-conceived task - the revival of armchair speculative metaphysics. I think this is a fair criticism. Lewis was very adept with logic and mathematics, but he was, as far as I can tell, insufficiently familiar with the sciences, and this shows in his metaphysics.

That said, the idea for which he is most often criticized -- his modal realism -- is now making somewhat of a comeback in the form of Tegmark's Level IV multiverse hypothesis. It's still a fairly fringe and very controversial idea, of course, but its now being taken seriously in at least some non-philosophical circles. It also ap... (read more)

3[anonymous]11y

Isn't modal realism much, much more dramatic a thesis than a mere multiverse? For example, modal realism should entail that there exists a world in which there is no multiverse, even if there is one in our world.

5pragmatist11y

Well, to relate the vocabularies of two theories you need the appropriate translation manual. The manual I'm considering here would equate a "possible world" in Lewis's terminology to a "universe" in Tegmark's terminology. According to Tegmark, all mathematically possible universes are real in some sense, and according to Lewis all metaphysically possible worlds are real in some sense (and Lewis's conception of metaphysical possibility seems pretty close to mathematical possibility). Lewisian worlds are spatio-temporally isolated from one another, as are Tegmarkian universes. The two theories do seem almost, if not exactly, equivalent. On the proposed translation schema, the appropriate Lewisian analogue of Tegmark's multiverse would be the entire landscape of all possible worlds. And so, on this translation, modal realism does not entail that there exists a world in which there is no multiverse. That would be equivalent to saying that there exists a world in which modal realism is false (i.e. the landscape of all possible worlds does not exist), which modal realism cannot entail if it is coherent.

0[anonymous]11y

Well argued, and fair enough. I guess the question comes down to this: I suppose I'm under the impression that the space of metaphysical possibility is much broader than the space of mathematical possibility. Would the two spaces be identical of a reduction if mathematics to complete and consistent logic had worked out? Does Tegmark take himself to be making an empirical claim, in asserting a multiverse?

4gjm11y

I've not heard that Lewis (note for other readers: that's David Kellogg Lewis, the mid-to-late 20th-century philosopher best known for modal realism, even though his dates don't overlap with Ramsey's) is regarded as "outright crap" by anyone of substance. But I'm not particularly well up on the internal disputes of philosophy. Who doesn't like him? Supposing that indeed some people do hold his work in low esteem, I'd guess it's because of his modal realism, which is for sure a major bullet-biting exercise and might strike some as silly. (I suppose he might also be contemned in some quarters for "political" reasons -- e.g., he was a fairly outspoken atheist, and I wonder what Alvin Plantinga thinks of him.)

4[anonymous]11y

I majored in philosophy. The only full-time, tenured analytic in my department thought that 1) modal realism was ridiculous, 2) David Lewis was incredibly smart, almost as much so as... I forget who he thought was the absolute smartest in recent times, but I think it might've been Kripke.

0KnaveOfAllTrades11y

Thanks. I can't remember the object-level dislike (i.e. who disliked him), my brain just held onto the meta of the fact that somebody trashtalked him, and indeed trashtalked him in a way that made it sound like their objections were shared by others. I also suspect it was because of his modal realism.

Multilevel voting rounds have the problem that they end up representing elite interests to a very unhealthy degree - round one is likely to select representatives with impressive accomplishments and credentials. Which means the pool of voters for subsequent votes is now more or less entirely from the very top social strata, and as such is not likely to elect leadership responsive to needs of the people. This is not just theory- it has been tried, and the results were bad. The one I would actually like to see tried is rotating sortition. Representatives are selected for five years terms at random, one year where they are non-voting observers, then 4 years of service. (to counter the inherent problem of throwing people straight into the job)

0Douglas_Knight11y

Do you have any examples of multilevel voting that test whether they increase or decrease the concentration of power? The only example I know is Venice, where they were introduced with the express purpose of decreasing it and they succeeded. Another example is American direct election of Senators and Presidents. I'm not sure what effect it had there. Plus it is confounded by the continual increase in the franchise.

3Will_BC11y

I read a very interesting book on election systems by William Poundstone called Gaming the Vote. His conclusion was that Score (aka Range) Voting was the best system on offer. A brief explanation can be found at rangvoting.org; it's a rather simple and intuitive system. As to idea number 2, I had a similar idea a while back, I called it fractal hierarchy, and a few thoughts occurred to me. First, it need not be democratic at all levels. I was thinking that if you wanted to select for rationality then the entry levels might not be very good at this. This led me to realize that this was rather similar to how the US military is structured, and they are generally positively regarded and considered quite meritocratic, so it might be a good way to do things. Another idea for legislative systems that I came across that is a merger between direct and representative democracy is called delegable proxy. The idea is that every member can vote on every issue, but they can choose to delegate their vote to a proxy voter, who can then choose to delegate all their votes to another voter, and so on, until you get a number of people with large chunks of votes. But for any issue, an individual can retract their vote(s) and vote how they wish. I think this system would allow for a lot of legislation to get passed, and would most strongly represent the popular will, but that is also it's greatest weakness, in that you get the issue of tyranny of the majority and ignorance of the masses playing a greater role. I am working on a project right now to put these and other ideas into practice, and will make a discussion post about it at some point in the future. If anyone is interested in helping me to better articulate my ideas before I post them, please let me know.

2Gavin11y

Interesting. Wouldn't Score Voting strongly incentivize voters to put 0s for major candidates other than their chosen one? It seems like there would always be a tension between voting strategically and voting honestly. Delegable proxy is definitely a cool one. It probably does presuppose either a small population or advanced technology to run at scale. For my purposes (fiction) I could probably work around that somehow. It would definitely lead to a lot of drama with constantly shifting loyalties.

4Will_BC11y

There is some incentive to vote strategically, but depending on the range and the other candidate on offer you might be better off voting honestly. If there's a candidate you dislike strongly, and a major candidate you only mildly dislike, you might give your favorite a 10, the mild dislike a 3, and the major dislike a 0, just to reduce the major dislike's chances. The worst case scenario, which you describe, is called bullet voting, and is basically identical to our current system, but if even a small proportion vote honestly it can improve the results. The researcher who made the graph at the bottom of rangevoting.org ran computer simulations of voter preferences compared with candidate values, and found that something like 10% of voters given their honest preference can improve results. I do recommend the book if you want to know more. I am very interested in delegable proxy, although it seems potentially dangerous and I think if it were implemented it would need to be tempered with some less democratic devices, but it could certainly make for some interesting drama.

3John_Maxwell11y

It seems like it would solve US 3rd party voting issues, e.g. if I prefer Libertarians to Democrats to Republicans, I could give the Libertarian candidate 10/10, the Democratic candidate 10/10, and the Republican candidate 0/10.

2roystgnr11y

You'd presumably plan to do that so long as the Republican was in first or second place, but if polling started to show the Republican candidate in third place, you'd want to switch the Democratic candidate's score down to 0. In the end, range voting boils down to approval voting, but with a trick to penalize people who are bad at math; and approval voting itself penalizes people who don't closely follow election polling. On the other hand, I'm not sure that voting weights based on mathematical aptitude and knowledge of current events are necessarily bad things, and even if they were they're still probably not nearly as bad as the hysteresis effects of plurality voting.

0Gavin11y

It would absolutely be an improvement on the current system, no argument there.

0Lumifer11y

Huh? The US military is certainly not universally positively regarded and I am not too sure about being meritocratic either. But in any case, it has nothing to do with voting systems, it's a strictly hierarchical organization where you shut up and do what your superior tells you to do.

0Will_BC11y

Well, highly regarded as far as US politics is concerned. A lot of people here like to see military service in a politician, and it's considered to be somewhat above partisan politics. And doing what you're told is a meritorious characteristic to have in the military, although I suppose it's far less meritocratic than some other organizations, it's ideal is that it is. Although you're certainly right, I should have said my statements were framed in the context of the US politics.

In theory, if a small group of people can be trusted to pick a person among them who is at least slightly above average rationality of the group, you could add lots and lots of levels of voting for people who vote for people who vote for people who vote on the issues.

3Douglas_Knight11y

For a millennium, Venice had a multi-layer system that alternated voting for voters and drawing lots for voters.

0James_Miller11y

Didn't this result in the election of Enrico Dandolo, who directed the 4th crusade to sack Constantinople, one of the most self-destructive acts of Western Civilization?

[-]Douglas_Knight11y130

Yes, Venice elected Enrico Dandolo. I'm not sure if "this" elected him, because he was of the intermediate period 1176-1268, but probably a multi-tier voting system.

It depends on your definition of "the West." Some people insist that Byzantium is not part of the West. This is probably the point where Venice joined the West. But is "self-destructive" a natural category? Wars are destructive. Would it have been less barbaric for the Crusade to follow its original plan and conquer Muslims? What does it matter that you, a millennium later, see Venice and Byzantium as one? That didn't stop Constantinople from enslaving its Venetian population in 1171.

Some people attribute the Renaissance to Greek manuscripts fleeing Constantinople when it fell a 250 years later. I imagine you condemn the sack because you think it lead to that fall. Was Constantinople doing anything with those manuscripts? They weren't having their own Renaissance. My impression was that already in 1200 Venice was the greater center of learning.

Anyhow, Byzantium wasn't his constituency. As I said, the voting system elected a leader with wide support who didn't use the mercenaries to sack his local rivals. Also, it achieved what Coscott asked for: a highly capable leader, who saved his city from an idle army, improvised a use for it, and, as a blind centenarian, lead the army to great victories.

I made the case for the likelihood of the Singularity here, and one of my favorite authors, John Wright, really didn't like what I said. My response to him is here.

6Punoxysm11y

I think your initial post was not the best / least-condescending way of talking about the singularity. But I think the main problem you encountered was that many of the commenters were religious and openly anti-materialist. If you think God created man in his image and that man's consciousness and cognition are special and linked to a divine, immaterial element called a soul, it's going to be hard to convince you of superhuman AI. Trying to start off with an argument for materialism conflated with an argument for extrapolating current scientific trends is just going to make them dig in further. So you really were in a lose-lose situation. But your response was solid; certainly better than the original case. A better point many of those commenters make is the distinction between extrapolation and creation; even if I disagree that singularity predictions are optimistic navel-gazing, it's still fair to say that the path to the singularity is not laid out in a concise and reasonable way (and pointing to Kurzweil's charts is a poor response).

[-]gwern11y220

So you really were in a lose-lose situation. But your response was solid; certainly better than the original case.

I thought it largely ignored the points and positions Wright made, and the counter-arguments weren't great. (I like Bostrom, but when someone makes a laughable claim like materialism is associated with no great philosophers, that's not a good time to bring him up; that's a time to invoke Hume, the Atomists and Stoics, Dennett, etc.)

If one is going to respond at all (and given how intemperate his response was, I would personally feel no obligation to reply), one should try to do at least a decent job which doesn't demonstrate one's opponent's claim that materialists don't know "enough philosophy to argue with a freshman" and possibly fostering a back-fire effect. (Hopefully wittily, like quoting some of Wright's bile and then sardonicly noting that Wright's religious conversion after a heart attack is itself an excellent example of materialism.) Strawmen are common enough without becoming a living one.

Chapeau!

3drethelin11y

Your case was kinda simple and condescending. On the other hand I can answer Wright by saying "Phineas Gage"

0[anonymous]11y

I don't think anyone denies that brain states have a strong influence on conscious experience, which is the only thing that Phineas Gage proved. The real question is how mechanistic matter can create subjective experience. For example, someone who was completely colorblind from birth could never understand what it felt like to see the color green, no matter how much neuroscience that person knew, i.e., you could never convey the sensation of "green" through a layout of a connectome or listing wavelengths of light. However, this doesn't mean that there must be some magical substance which produces experience, and it does not mean that Whole Brain Emulation and AGI is impossible, which is the hasty conclusion reached by many non-materialists. Rather, it only poses problems for those who say that brain states are the same thing as conscious experience.

Also see orthonormal's posts here (and accompanying discussion). I remember the point being similar to "I might know all about heroin and how I'd respond to it, but taking heroin means that certain neurons release chemicals in ways that I don't have conscious control over, and it e.g. will cause memories to be formed that I could not form normally."

0jacob_cannell11y

Philosophy (which today is mostly a historical field - the study of old speculations) is not the right place to find the answer to this question. Computational neuroscience is. The 'problem' is overstated - the mindstate of observing green through information flowing from the retina through multiple layers of visual cortical processing is in a wholly different category than the congenital colorblind's mindstate of thinking about green as an abstract linguistic concept. The two mindstates are completely different and involve largely unrelated computations in functionally distinct minds.

2MrMind11y

I fail to see how Wright's answer is even remotely relevant. Let's say that for some mysterious reason brains have a door that connects them to some metaphysical realm that silicon-based devices could never have. Does this changes the fact that a properly programmed computer can beat any human at chess or checkers? Does this changes the fact that cars can self-drive successfully for thousands of miles? Does this changes the fact that right now a living organism is being simulated at cellular level? The only thing that distinguishes the Singualirty scenario from a simple observation of the state of the world is the assumption that there is a point after which an AI can exponentially self-improve, and that will have an exponentially large effect on our society.

0James_Miller11y

The fact that Albert Einstein existed wouldn't provide as much evidence for the future likelihood of science-doing AI if brains had such doors, although you are correct that this wouldn't mean we sill could not develop such AIs.

I was trying to figure out how big 3^^^3 was, which led to the following interesting math result. How high would a power tower of 3's have to be to surpass a googolplex raised to the googolplexth power? For what value of X is (3^^X)>(googolplex^^2)? I don't have the full answer, but an upper bound for X is 16. A power tower of 3's 16 high is guaranteed to be vastly larger than a googolplex raised to itself. And when you consider that 3^^^3 is a power tower 7.6 trillion 3's tall... it's way larger than I thought.

5gjm11y

In what follows, all logs are to base 3. Definition: [a,b,c,d] := a^(b^(c^d))), etc. Lemma: log [a,b,...,z] = log a^[b,...,z] = (log a) [b,...,z]. Definition: {n} := [3,...,3] with n 3's. Lemma: log {n} = {n-1}. Definition: G := [10,10,100]. OK. So we want to know when {n} > [G,G]. Taking logs, this is the same as {n-1} > G log G = [10,10,100] log [10,10,100]. Taking logs again, it's the same as {n-2} > log log [10,10,100] + log [10,10,100] which (unless it comes out amazingly close) is the same as {n-2} > log [10,10,100] = (log 10) [10,100]. Taking logs again, this is the same as {n-3} > log log 10 + log [10,100] = log log 10 + 100 log 10, which again is basically the same as {n-3} > 100 log 10, and now we're in the realm of small numbers and we find that [3,3] is too small but [3,3,3] is way more than enough. So I'm pretty sure the answer is that you need six 3s in your tower. Since it's easy to get this kind of thing wrong -- which is why I introduced notation and lemmas intended to make the manipulations as simple as possible -- I just did it again a different way (a couple of steps of algebra on paper, plus some ordinary floating-point arithmetic on a computer) and without the informal throwing away of much smaller bits. I can confirm that five 3s aren't nearly enough and six 3s are way more than you need. [EDITED to remove a definition and a lemma that I never actually used, and to add a little clarification.]

2gjm11y

By the way, here's the handwavy heuristic version that gives the right answer. When you are comparing two exponentials with really big exponents, only the exponent really matters even if the difference in bases is huge (unless it's really huge or the exponents are really close). So the following should all be the same: * 3^(n)^3 versus G^10^10^100 where G = 10^10^100 * 3^(n-1)^3 versus 10^10^100 * 3^(n-2)^3 versus 10^100 * 3^(n-3)^3 versus 100 * NB you can do all the foregoing in a single step: just cross out the 3 bottom levels. and now we can see that 3^3 < 100 but 3^3^3 > 100, so n-3=3 and n=6. If the detailed algebra in the parent isn't enough to make "look at the exponent and ignore the bases" plausible, here's another way to see it that happens to work neatly in this case: (10^10^100) ^ (10^10^100) = 10^(10^100 . 10^10^100) = 10^10^(100 . 10^100) = 10^10^10^102 so the difference between 10 and 10^10^100 on the base is the same as the difference between 100 and 102 three levels up! ... EDIT, on happening to reread this days later: No, I slipped up in the calculation above and the result is actually a lot closer. (10^10^100) ^ (10^10^100) = 10^(10^100 . 10^10^100) = 10^10^(100 + 10^100) = 10^10^10^(100+teenytiny) because 10^100 + 100 is barely bigger than 10^100 at all. In fact it turns out that "teenytiny" is about 4 x 10^-99. So: the difference between 10 and 10^10^100 on the base is the same as the difference between 100 and 100 + 4e-99 three levels up.

I'm hoping to get a quick reaction to the following situation: I'm leaving a job in Asia and want to look for work in my native US. I've been away for two years. First I thought that since the cost of living is much lower here, I should do the job search here and only return to the US after getting an offer. But based on "local candidates only" restrictions in job ads and some recent advice I got on Quora, I'm now thinking it might be best to show up soon in California with $6K in savings, check in to a cheap hostel and look from there.

4gjm11y

Most prospective employers will want to interview candidates before making offers. If you are living in Asia, you will not want to be constantly flying back and forth to interviews. So you may have to have fewer (reducing your options) or schedule them all in a small number of blocks (also reducing your options since some prospective employers won't have flexible enough schedules for that to be easy). How much this matters depends on how tasty a prospect you are for employers, how much you care how good your first job is, what field you're looking to work in, etc.

This fail-safe is only an actual net gain if you would rather die than see the aftermath of nuclear war, but don't want to go through all the trouble of committing suicide manually.

Moving to New York in order to make sure that a nuclear war would kill you is like getting a DNR notice put on your bed in hospital. It may be a sensible thing to do, but if so is independent of MWI.

7Manfred11y

If we want to talk about majorities, most people think quantum mechanics is too complicated to worry about. Smaller fractions think that quantum mechanics means humans have souls, quantum mechanics will let you be in two places at once, and that quantum mechanics fix quantum cars. In a rare display of majoritarianism, the "don't worry about it" demographic is probably right. Egan's law - it all adds up to normality. "Quantum killed" is just a more complicated way of saying "normally killed," because quantum mechanics is how reality has always been.

2Tenoke11y

Good job on arguing against majoritarianism, but you haven't provided any arguments as to why the view that I attributed to a majority is wrong.

2Manfred11y

If you had all the prerequisites, you would not need the argument. So I'll give you a short overview of the point, and then just link you to some articles. Quantum immortality is not fundamentally about quantum mechanics. It is about whether you can live forever by defining yourself as a person who doesn't die. "You" can, but you can't. Links: You could learn some quantum mechanics. Then look into where the relative state interpretation (MWI) comes from, by reading Everett's quite accessible paper. Key thing that you will understand after this: probability is a measure, and norm-squared measure is all there is. Look into the foundations of VNM decision theory, but maybe also temper it by reading Savage's decision theory. Now you should understand how quantum mechanics fits into VNM decision theory by providing a measure. At this point it all adds up to normality - you make the same decisions using any interpretation of quantum mechanics. Now on to definitions: A Human's Guide to Words on why we have them. The Metaethics Sequence on what we're talking about when we say "I want to live forever." At this point, if not earlier, you should be able to conceive of an agent that actually does believe in quantum immortality, and acts accordingly - and also an agent that doesn't believe in quantum immortality, and acts accordingly. Experiment: Attempt to define yourself as a rock, thus increasing your lifespan. Did it work? Why or why not?

3komponisto11y

The assumption of quantum immortality is that once some branches of "you" are gone, then you have to define "you" as the remaining branches. It's about the impossibility of expanding the definition of "you", not the possibility of expanding it.

0Manfred11y

I think there are some additional assumptions required to get you to Tenoke's example, of dying in a nuclear blast not counting as a downside of living somewhere, because of quantum immortality.

-2Tenoke11y

That is just not correct, it is about how under some definitions of 'you', you don't die, and some people use those definitions regardless of QM (pattern identity theory uses a definition compatible with quantum immortality for example). The real issue with quantum immortality is whether measure matters, and as far as I know, this is an open question (although, I suspect there are plenty of good resources on the question which I haven't seen)

0Jiro11y

If you have a choice between living in Sitka and living in New York, isn't that a choice that splits the worlds too? So in one world you'd be living in Sitka and in another world you'd be living in New York. In general, it would seem like "choose X so that I am in this set of worlds and not in that set of worlds" doesn't work--you're always still in the set of worlds where you made the opposite choice. Even "choose X so as to increase my measure in this set of worlds and decrease my measure in that set of worlds" won't really work. By definition, the whole set of worlds encompasses all choices. You can't choose X so as to affect something about your situation with respect to the worlds. What would that mean anyway? Would there be a meta-set of sets of worlds, and there's a branch of the meta-set where you chose X and increased the measure of part of the set, and another branch of the meta-set where you didn't choose X and didn't increase the measure of the same part?

0KnaveOfAllTrades11y

'Died from nuke in London' is a vague thing, but even if you choose a boundary by which to delineate it, that partition does not carve reality at the joints. There would probably be intermediate states of some measure where you suffer but live for some time after the initial blast, and probably be states of lesser measure where you are unharmed or even gain from the blast. It might still turn out that the measure/probability/whatever of the suffering states is low enough that it's still worth leaving yourself open to being nuked, though. Like, maybe P(Alive|Nuked)=10^-5 and that's an acceptable proportion of worlds where you live through the nuking since you do successfully die in the vast majority of worlds. But if you're not sure, all else being equal, you'd want to pick the place within London that would be most likely to kill you if a bomb hit, rather than some obscure, heavily-sheltered place on the outskirts where you'll just about live and suffer after the blast. In general, it's pretty suspicious if death seems to be the fundamental deciding factor in such matters (e.g. whether to live in London, whether MWI vs. Copenhagen matters); the reason people suspect so is anthropic--we can't observe (parts of) worlds where we are dead. But since 'I' and 'dead' are going to be fuzzy notions that do not carve reality at the joints, we should not expect them to be fundamental to decision-making in multiverses, even if they are efficient shorthands. It's important to bear this in mind with MWI and anthropics. lolol

I used the linked resources and didn't come off much wiser, but I guess regoing over he basics is only good. I guess it hammered home that there is convergence on the double slit experiment. However in all these things it's a scenario where you start off in one world split it into multiple and then coverge to a result world. However in my understanding pure states are hard to prepare. There are a multiple worlds where we run the experiment a little later or in a little diffferent conditions. Won't those worlds also have a chance to effect our experiment in addition to the "intra branch" interference? There was a side mention that in multiple worlds there is a "branching structure". I guess it might be characterise long distance behaviour but in short range convergent interference can play a big role?

That said, don't expect many good ones. 1) QM is, believe it or not, difficult (big surprise, right?) 2) what needs to be said really depends on the directions your thoughts bend when being exposed to it - covering every blind alley that could screw someone up would slow everyone down to a crawl, unless you go very formally, and then see point 1 even more so.

A set of n entangle particles is a function from R^(3n) to C. It's assigning a complex number to each configuration of particles. Since there are n particles, and each particle has three real dimensions, it comes out to 3n real dimensions. It's a local fact. Knowing just that point won't work; it only gives you the positions of the particles, but having an arbitrarily small neighborhood will give you the derivative, which gives you the momentums of the particles. In stationary waves, you're dealing with something that only has a small set of states. It has to converge as fast as it splits, since there's nowhere else to go. If you stick a particle in an infinite universe, there's no stationary wavefunction. It doesn't happen as much thanks to increasing entropy. Everything starts from the big bang, but it can end anywhere. That's not to say it doesn't happen. The double slit experiment works because the universe where the photon passes through the left slit and the one where it passes through the right slit intersect again. It doesn't work when you record which slit the photon passes through, since one universe now has a detector saying "left" and the other one has one saying "right", so they're not the same universe. As long as it's stable it will. Once something chaotic happens, it will start splitting. Imagine you're putting a drop of dye into a pool. It doesn't break down or otherwise stop being dye, but it does dissipate. It's the same deal with quantum physics. The measure is preserved, but later on it's just spread out more. Also a good example of converging worlds. If the bomb doesn't explode, the universes can converge again, causing destructive interference in places. If it does explode in one universe, they can't converge, so those places that would have had destructive interference can still happen, and if they do, that proves the bomb exploded in another universe.

0Slider11y

But won't the physcial underlying reality still be contrained to a fixed dimensionality space (if it is not R3)? That is can the function be composed as a R^(3n) function to R^3 to C? I thought particles are bumps in a field not that each bump makes it's own field to contain it.

0DanielLC11y

I'm not sure what you're trying to say here. Are you suggesting that it's a function that maps a point on R^(3n) onto functions from R^3 to C? Like you plug in a point in R^(3n), and you get a function from R^3 to C? If you have one particle, it can be in any position in R^3, so you have a function from R^3 to C. If you have two particles, then they can be in any combination of positions with their own values. For example, if one is a proton and one's an electron, and there's not enough energy in the system to split them, then either of the particles can be anywhere, but they still have to be close to each other. If they each had their own distinct wave function, that wouldn't be possible. It works because the system as a whole has one wave function, and it's close to zero for any configuration where the proton and electron are not close together. Does that help at all?

0Slider11y

If they are of the same type then a point (A,0,0,B,0,0) would result in the same state as (B,0,0,A,0,0) I would understand this as those points mapping to a same R^3->C function. I thought there was no billiard balls and that the wavefunction has ontological priority? If I had two separate particles of different kinds in the same position I could tell from the R^3->C undulations on which kind of particle it is. I can understand it might be handy to order the undulations by their centers point-like shorthands. I thought that the real mechanics happen on the R^3->C and if there are mechanics on the higher dimensional structure they are an emergent consequence of that level. Like I can index me throwing a rock on the lake by where my rock lands. However this kind of description can not describe any two simultanoues throws or things like throwing a stick sideways into the water. The wierder throws I make the more things I need to spesify. However if I somehow manage convey the shape of the water there is no way it can be inadeqaute picture of the wave (such as if I make a topographical map). And in no way of splashing can I add or remove water or make it do anything but go up or down. The quantum field takes on value of C so it has "more room" than simply going up or down. However in no way of taking on those C values does the lake change in volume or dimensionality.

If they're bosons. If they're fermions it would be opposite state. They map to the same (or opposite) C value. The real mechanics happen on the R^(3n)->C. If they're not very entangled, you can separate it approximately into f(x,y) ~= (g(x),h(y)), where x and y are the positions of the points in R^3, f is a wave function from R^6 to C, and g and h are wave functions from R^3 to C. I'm not sure what you mean by this.

Even if I knew the neighbors in space in this configuration wouldn't I still need to know the other configurations state? Depending on whether interference is enabled or disabled by monitoring the path in the double slit experiment I could be spatially close but far in configuration space in the middle receiving point. There is off course a linkage with the spatially close neighborhood as it too is influenced by the same offworlds. But isn't it so that an event such as a bomb going off in another world will not have (perfect) precursor trace in this world but will have some point of first effect. I was thinking off solid classical stuff that quantum mechanically still pulses. Like if I stick atom in a empty universe the electron will hang around the nucleus. I guess the direction of wandering of the whole atom would still spread. Does stuff not evaporating from your hands need a converging contribution from the environment? I find the idea a little spooky. How come the effects of light on the air is not enough to "break the spell"? The splitting of worlds is not pointlike but I have very much trouble imagining what is "halfsplitting" like. I was thinking if it more like oil that does form droplets as it is interacted with but sticks together instead of dissolving when left to it's own.

I'm not sure I understand. Are you saying that, in addition to knowing what the nearby universes are, you need to know the value of the waveform there? I was just talking about the value of the waveform. You automatically know what the nearby universes are. They're the ones just like yours, but with a few particles moved by epsilon. In principle, the electron can go anywhere, but it's being forced near the atom, so almost all of the waveform will be there. There's not enough room for it to spread out. It interacts with nearby universes. The universe where the photon changes the direction of a molecule of air on the way to the sensor array interferes with a universe where the photon took a different path and the air was already going that direction. This doesn't happen with a sensor, because any sensor that's likely to say the photon went through the left slit when it really went through the right one isn't very good at sensing. You said that multiple splitting of worlds seems like it would reduce measure. I showed an example of something dispersing but not reducing, showing that dispersion does not imply reduction. The fact that there are many things that don't disperse or reduce is irrelevant. Placing oil in droplets results in the droplets sticking together, but this is due to the cohesive force of the water. It has nothing to do with conservation of oil.

The wavefunction is the same object shared by all universes, correct? Thus a point's spatial neighborhood in one universe is not the full neighborhood of the point. I would imagine (if it's a coherent notion) taking a derivate only "within one universe" would have a different result than taking it with the full wavefunction. Wouldn't an air molecule already going one way need a separate cause to be going that way (as in something that pushes it that way (probably another air molecule))? And wouldn't that put it simply further in configuration space (ie make interference less likely)? I have still trouble imagining when interference happens and when not. You need a path in configuration space to connect two points to have interference? And if the distance is big there are more chances for the intervening configurations to spoil the interaction? It seems the air gets scrambled. I guess any device that could detect the scrambling would be as good as detecting the particle directly?

0DanielLC11y

I meant the universe's neighborhood, at taking the derivative of the universe's wavefunction at that point. Since the wave function is continuous, if you look at a universe with a particle nudged just a little bit, the wave function won't change much. It's not like you're moving that particle very far. No. If the air only ended up in that orientation if the particle went in a particular direction, then the system would decohere, and the detector would be unnecessary. Since the air can end up in the same orientation either way, there's no way to detect it.

If the photon is going through the other slit it's several molecule lengths away. So the molecule just curves/collides with empty space as if the photon was there? I don't understand how it can touch the air and not decohere.

The interactions are weak. If we had some super-sensitive air pressure detector that could tell which slit the photon had gone through, we'd get the same results as when we measure which slit the photon has gone through (that is to say, no interference). But actually such a thing is impossible; maybe a few air molecules close to the photon path will get their state entangled with the photon state, but they don't interact enough with other air molecules for the entanglement to spread through the whole room. So you get a case rather like the one where you record which slit the photon went through but then destroy that information without reading it - and you do see the interference.

-2DanielLC11y

There's another universe where the air was already going in that direction. Since the photon isn't going to nudge it much, it's a really similar universe, so it has about the same wavefunction as the universe you were looking at to begin with.

I just read an AI thriller by Greg Iles called 'The Footprints of God'. Don't want to spoiler it, so I'll just say that it strikes me as singularity-lite.

Also, here's an objectivist Harry Potter treatment.

Downvoted for linking a memetic vaccine. (Yes, memetic immune reaction to memetic immune reactions.)
