Nuclear war probabilities are useless - counter to the nuclear gambler’s ruin

> Putin does not roll a dice every morning and launches a nuclear missile if a six shows up. You wish! The problem here is that Putin is not rational.
- SvenSchnieders 5y ago
  He might not be rational, but surely nobody can argue that he is insane to that level – at least, I haven’t seen anything that suggests that.
  - raducu 5y ago
    He's just a little bitch screaming to everyone's face "I'm gonna use nukes!" hoping we give him what he wants. What does he have to lose by alluding to using nukes right now? Nukes are the only thing stopping the West from rolling into Moscow, the magic wears off if the clock strikes 12. Nukes only work for the 15 minutes before they are used, Putin and Lavrov keep crying "Nuklear wolf!".
    - zabzonk 5y ago
      > Nukes are the only thing stopping the West from rolling into Moscow Yeah, tell Napoleon and Hitler how easy that is.
      - raducu 5y ago
        Napoleon and Hitler were not defeated by Russia. Napoleon/Hitler could have raised 3 more armies if they were fighting just Russia. On the contrary, Putin is the new insane and isolated Hitler.

        The Soviets destroyed 3 times as many German divisions as the western front allies combined.
        raducu 5y ago
        Because the german forces were split and the allies supplied USSR, otherwise the USSR would have collapsed. Without the allied material support and the german forces being split, the USSR would have been deffeated. It's not something that I would have liked, just the truth. People claiming Russia to be invulnerable miss the real lesson of those conflicts -- the ballance of power. The ballance of power is set against Russia right now, if the West remains strong in its unity and resolve, Russia will collapse.

  This makes me chuckle. The Bad Orange Man played the "insane king" role really, really well. Everyone was on their best behaviour until he left office. Peace talks in the Middle East progressed. Russia stayed in their borders. North Korea huffed and puffed and ultimately did nothing. Trade with China became more favorable to the US. It's almost like his foreign policy was effective. To your point: Putin isn't nuts. He's just a really good politician. He's pragmatic and knows the value of being seen as "crazy" and "he might actually launch a nuke".

    The same was said about Nixon during the Vietnam war (which he inherited, but would never have started) but it is a really risky stratergy once you start ramping up the mania levels and passing them on to your nuclear forces, which Nixon (a good president, all in all) nor the Big Orange ever did.

  So? Whoever is insaner wins? Nah, remind Putin that we all saw how much the russian army sucks and in case of nuclear war the US still wins after they get out of their bunkers.
  - ghufran_syed 5y ago
    with the greatest respect, this is the greatest evidence of insanity I’ve seen in this thread…
    - raducu 5y ago
      This is the only approach that works and won the US the Cold War. A credible threat that if the USSR dared to use nukes, NATO would use nukes against the USSR. Do you think Putin is a genious and it didn't cross other USSR leaders minds the same idea -- "surely, the USA would not use nukes again us if we used just a few nukes against a weaker NATO member"? The only sane answer is to absolutely make sure the other guy knows you're going to use nukes the second they use them. Macron's retort to Putin needs to be shouted from the rooftops -- we also have nukes, you're not that special.
      - k__ 5y ago
        Also, the question is: if Putin orders it, would it happen?
  - altdataseller 5y ago

      This is actually exactly what Putin said - that NATO is much stronger, but if there is a nuclear war, it's going to be bad for everybody.

dontbeevil1992 5y ago
Another issue with this logic is that the probabilities are not independent. Saying that you have probability x of nuclear war every year and so probability (1-x)^n of no nuclear war in n years assumes independence. In fact, if you don't have nuclear war on year 1, I would assume that the reasons for that lead to inferences and correlations that would affect the probability of nuclear war on year 2, possibly making it lower.
- LeonB 5y ago
  No, that’s not quite right. Measuring “did we have a nuclear war?” is not the input you’d ever want to use there, it’s only one binary digit of information. Instead take info like “did we have events/incidents with a high potential of nuclear war?” If three “Cuban missile crisis” level events happened in year X, then the probability of nuclear war in year x+1 is higher than it was in other years — even though nuclear war didn’t occur in either year. If national leaders make no statements threatening war in year A, then it’s probably safer than year B where there were 100 such threats.
  - dontbeevil1992 5y ago
    I might not have said this clearly enough - I'm not saying that conditioning on "did we have a nuclear war" will change the probability to be less. I'm saying that the event "did we have a nuclear war in year n" is not independent from "did we have a nuclear war in year n+1" "n+2", ... because there are shared factors influencing them. Therefore the model of independent probabilities multiplying year over year and seeming to imply that nuclear war is inevitable because (1-p)^n goes to 0 as n grows doesn't make sense mathematically speaking.
    - LeonB 5y ago
      Ok. I think the question that we want to ask from the model is more like: “What is (one minus (What is the chance we have had 0 nuclear wars by year “now plus 70”?)” So if there is a nuclear war in year n+3 (for example) it’s effect on year n+4 is irrelevant as the answer to the question is already “0% chance of no nuclear wars by year 70”. So the angle you’re initially coming from is not quite relevant. We can then turn that a bit though and continue your point — we can rephrase your claim to be like this, for example: “if we have had 0 nuclear wars in the next 69 years, then surely that would lower the probability of a war in year 70.” And to that I’m saying — actually no. Or rather: not necessarily. Or more accurately: not much! The info of “we’ve had no nuclear wars in 69 years” is not what the model would care about. More likely it would care about, running the model a bunch of times, in the cases where there no wars in the first 69 years, how many times is there a war in the 70th year? And “brink of war” or “HPI” scenarios would be a much better indicator than the simple absense of nuclear war in those first 69 years. Maybe better to said “there is a lot more information in the question of ‘how many times have we been on the brink of war’ than there is in the answer ‘did we have a nuclear war yet? No’. It’s more about that “how much info is there here?”

A useful metric - how often does a national leader willing to start a nuclear war come to power in a state with nuclear weapons? That's measureable from historical data.
- jeremyjh 5y ago
  Which data would that be? We don't know if anyone is willing to use nuclear weapons against a nuclear power because no one has ever done it.
- daliusd 5y ago
  How? We had no nuclear war yet. How can you know that leader is willing to?
- AnonCoward4 5y ago
  It's not measureable. First of you need to account for many having the same weapons (MAD) and you also need to account for the knowledge of the impact of these weapons. The knowledge does change the probability for someone willing and able to use these weapons to come into power (as well as the whole structure around the usage).
- vkou 5y ago
  You're missing half the equation. 'Every'[0] national leader is willing to start a nuclear war given some particular set of circumstances. There's always some line that they will not allow their enemies to cross. The difference between leaders is what those circumstances are. It's in where that line is. [1] Public communications on this subject have to be taken with a pound of salt. It's in every nuclear nation's interests to claim that line is further out than it really is... As long as they believe that broadcasting the claim itself won't start nuclear war. It's also in every nuclear nation's interests to be very mindful about where their adversary's line is. [0] Okay, there might be a closet pacifist somewhere that won't use them in any situation, but if there is, they certainly aren't broadcasting that. [1] So far, we're batting a thousand for 'No national leader whose last name was not Truman started a nuclear war in a situation where his state was not fighting an existential war'. This statistic, unfortunately, is not particularly helpful.

So this is basically saying that it's extremely hard to estimate these tail-event probabilities reliably, and therefore conclusions should not be taken as gospel. But we mostly knew that already?
hankchinaski 5y ago
the gambler's ruin fallacy is a typical example of cumulative probability. cumulative probability measures the odds of two, three, or more events happening. there's just one catch involved: each event needs to be independent of the others. you can't have the outcome of a first event influence the probability of the next. which we know for nuclear war it be dependent upon the probability of previous events. ie. if a nuclear war starts, either everyone gets annihilated, which in turn influences the probability of the next nuclear war to be zero, or one or both of nuclear powers get severely damaged with catastrophic consequences, therefore influencing probability of future similar events
bayesianbot 5y ago
On the other hand we have a lot of data points of humans and nations using every available edge to expand their power throughout history. Also we have made social systems where narcissistic greed and lust for power seems to get pretty much rewarded with more money and power, and misinformation runs rampant. More powerful weapons systems will get developed until MAD might not be certainty for the aggressor, if bombs can be delivered stealthily in minutes. Or at least MAD might get tested with one warning shot, delivering a message of "what is your actual defense going to be, I don't really care about the world anyways" I don't really see it as much as daily roll of a dice but more of a system that might guarantee to force us down that road some day within a few generations.
- empressplay 5y ago
  People think MAD is 'we launch everything at our enemy if we see one missile' -- this hasn't been the case for decades, since all sides can see launches almost as soon as they happen. So yes, 'warning shots' are now effectively the start of such a conflict. Where MAD comes in is it's generally accepted that if you do that your opponent is likely to lob one back. An eye for an eye. I suspect capitals of nuclear powers are special cases though, and would generally be avoided unless absolutely necessary. I don't think Putin needs to actually start nuking European countries to get his way though. He knows the Americans simply do not have the resolve to escalate a nuclear confrontation unless its own domestic security is threatened. I don't think the UK or France would either. NATO is kind of a sham. But Putin isn't worried about nukes in Ukraine as much as ground troops. The fact that he is suggests he's not worried about getting nuked himself, which is actually a positive sign, for everyone except Ukraine. ETA: I just realized in Biden's SOTU he said the US would defend every inch of NATO territory and make the Russians pay, which was clever, since neither of those statements suggests either an invasion of Russia nor a nuclear response, only that Russia wouldn't be able to hold the territory and that there would be repercussions of some kind. Not a dumb guy.

  > The ways we could end up in a nuclear war are frightening to the point of madness. Haven't read the book, but I watched Dr. Strangelove when I was young(er). What made the movie great to me was that it made me realize that, although there is a nuclear "safety net", it was designed and controlled by humans — flawed humans who don't always behave rationally and who may not act in the best interests of humanity.

  ... and yet we haven't. Every day since WW2, things could have gone wrong. Every day, for 76.56 years. 918.79 months. 27965 days. I think we'll be fine. And if I'm wrong, you probably won't be able to tell me! :) Edit: not sure (and don't really care) why this got downvoted, but I meant it as a morale boosting thing, not as a probability calculation. Things could have gone horribly wrong so many times, but they haven't so far. That personally gives me hope for the future.
  - abvdasker 5y ago
    I hope you're right, but this feels like an instance of the hot hand fallacy. In a historical sense, nuclear weapons haven't existed for very long. 76.56 years without a nuclear attack is less than the life expectancy of one US adult. It's too soon to tell.

> Put differently, Putin does not roll a dice every morning and launches a nuclear missile if a six shows up. Even he himself cannot meaningfully answer the question “What’s the probability that Russia will launch nuclear missiles 6 months from now” unless his answer is 100%. It depends on many factors, like how NATO reacts and how strong the Ukraine military is, none of which can be captured by probabilities. There's a guy[0] who spent a career analyzing and writing about these things. His most recent take is that by refusing to get directly involved in Ukraine, NATO creates an understanding in Putin's mind that it wouldn't get involved in, say, Latvia either. According to Piontkovsky, (to Putin,) there's no essential difference, and the (lack of) NATO membership reason provided by NATO is a lame excuse indicative of a lack of resolve to commit, NATO member or not. So Putin is willing to keep upping the ante until NATO folds and becomes irrelevant.

- virgilp 5y ago
  I don't buy this. The NATO message was clear & consistent that they will intervene in case of an attack on a member - there's 0 reason to believe otherwise. In fact, I'd say that current response in Ukraine enforces this (though it's not a NATO member it got plenty of offensive equipment, intelligence, money, support, etc. - basically everything possible short of direct declaration of war / direct military involvement from all NATO members). Keep in mind that Putin's mythos was blown to pieces, there's no way he can (politically, if not physically) survive this. And he probably knows it. This is the weakest position he can be in - if the west attacked him, he could at least mobilize the Russians to "defend against western aggression" and could even justify the nuclear bombs to his generals; As things stand, his rhetoric and position are very shaky (he's not being defeated by mighty USA, but by the "weak" Ukrainians who "aren't even a nation")

I would say that probability is 100%, having a corrupted system, with corrupted people and madmen, on all sides, it is not question of "will" but rather "when"...
- WJW 5y ago
  The system being corrupted makes it less likely to have nuclear wars, not more? Idealists are willing to blow up everything for their ideals, people who are only in it for themselves have nothing to gain by destroying the world.
  - NiceWayToDoIT 5y ago
    Idealism, nationalism, fascism... are forms of corruption, but in this case there is inherited problem with aristocratic corruption, the one that allows people with lot of money to command most deadliest weapons on the planet. When you think about nowadays leaders and there structures are not very different from mafia bosses behaviors, and I am not talking about Russia only, each super power has the same problem.

The whole article is basically about different interpretations of probabilities -- probabilities as reflecting the degree of belief, vs pure frequentist ones. Both make sense, they just need to be used in different situations and need to be interpreted differently.

> Putin does not roll a dice every morning and launches a nuclear missile if a six shows up Very true. Using, essentially, the infinite typing monkeys idea to say that a nuclear war is bound to happen eventually is just a pseudo-scientific rationalization of war. Put this way, almost anything becomes certain if you completely ignore the fact that you don’t know P(nukes|war) since we have no further data to base this on. Even a coin flipped once or twice might not be heads and tails. The idea of P(heads) = 0.5 is that eventually, as the flips extend to infinity, it equals 0.5. This would be similar to someone living in the Black Plague saying “since 10% of Europe is dying per year, in 10 years we will most certainly be extinct.” I don’t know the technical or formal name for this fallacy or line of thinking, so I’ll just call this gross oversimplification.
- LeonB 5y ago
  That’s not how the modelling works. That’s a mischaracterisation, a straw man argument.
hashimotonomora 5y ago
What is an ensemble probability of something that has never occurred and is essentially impossible to model? Have you seen all infinite alternate universes? Probability does not make sense. Compare the following: What is the probability that you will die today? What is the probability that you will die today given that you belong to the category of people with A_i characteristics and whose ensemble probability of dying on a given day has been measured?
- LeonB 5y ago
  The insurance industry does a pretty good job of “what is the probability that you will die in the next billable period” - but they would never reduce the bet to “what is the probability that you will die today?” You say it’s “essentially impossible to model” something that hasn’t occurred before. Nations have engaged in a lot of wars. Nations have engaged in a lot of wars they could not possibly win. People have committed suicide to harm other people. Many many times. Nations have developed weapons and then used those weapons on other people. Countries that have engaged in arms races and stock piled weapons have then gone to war. Many times. In some decades we do more of these things and in others we do less. To say it’s hard to model, or the models are imperfect (as all models are) - fine. To say it is impossible to model - that’s very naive.
  - hashimotonomora 5y ago
    If you are lost in a city would you rather have the wrong map or no map at all? The person that has the wrong map and thinks that it’s the right map is the one that’s naive. Regarding insurance companies, you are conflating ensemble probabilities with time probabilities. Insurance companies can estimate the ensemble probability of an event in a group of agents which belong to a certain category and not the time probability of said event on a single agent.
    - LeonB 5y ago
      I’m pretty sure we’re in agreement in the insurance policy part. If I buy a policy to cover my risk of death for the next X years, the insurance company uses the ensemble probability of the group to price that policy (and believes that the risk of me knowing more than them is covered by the fact they’ve factored that in, plus that they’ve insured multiple people in the group and the aggregate will be good even if 1 policy isn’t.) If I said to an insurance company — okay I want to buy a policy that only covers me for one day - they would not do it. Firstly of course the transaction costs would swamp the cost of the policy, but let’s ignore that by pretending they use some magical technological solution (digital contracts… hardy har har) The second reason they wouldn’t do it is because that’s not how their model works. It has to smooth over time. Over a year, over a lifetime - not over a day. The third reason they wouldn’t do it is because the information asymmetry now dominates. My knowledge of whether I’ll die tomorrow in particular is better than their model. I’m able to price the policy much more accurately than them. The fact I want the policy is a big red flag. (They do offer some very short term contracts such as holiday insurance — but those disclaim every imaginable pre-existing… which is out of scope for this discussion as it’s not something we can do with nuclear risk) I think we more or less agree on that stuff. Don’t we? What I’m saying about it is that just as we all know that insurance policies don’t make sense when you reduce it down to thinking about an individual person on an individual day — the nuclear war modelling doesn’t work when (the author of the article) reduces it down to saying it’s like suggesting that Putin flips a coin each morning. The most likely reason an author would pretend that the models claim such a plainly ridiculous thing is in order to ridicule the models, about a claim they did not make. In this way it is a straw man argument. They are recasting the original assertion into something that is easy to attack. It’s not a well intentioned thing to do. That’s what I’m saying about that.
LeonB 5y ago
In safety we try to prevent rare events (such as death) and these are rare enough that “past deaths” are not a useful way to predict the likelihood of a death. A crucial metric that occurs more more often and does help predict deaths is “HPI” - high potential incident. A worker eight metres in the air dropped a spanner. It thudded on the ground, harmlessly. No one was hurt. No problem, right? That’s a HPI. A workplace that has a death will have had many HPIs. The dice-roll is not “it’s a new day, we roll the dice”. When a HPI occurs, that’s when we roll the dice. Or in nuclear war estimates: a HPNWI occurs (high potential nuclear war incident). The Cuban missile crisis springs to mind as a particularly big example. But many many smaller HPNWI’s have occurred. Border skirmishes between nuclear powers. Sabre rattling by nuclear powers. Elect a president who uses threats and brinkmanship. Do this year in, year out. The dice is rolled not because time passes but because risky decisions are made and risky actions are taken, over and over and over and over and over and over, year in, year out.

  - apendleton 5y ago
    I took it to be: the original author's point was that nuclear attacks are so rare and our sample size so small that we can't use history to predict their occurrence in the future. This commenter is saying the typical way to handle situations like this is to look for more-common events that are proxies for the less-common ones in some predictable way. To give a different example of my own: on an intersection-by-intersection basis, pedestrians dying from getting hit by a car is relatively rare, so if it's perceived that a particular intersection is unsafe and the design of the intersection is modified with a goal of reducing the chance of death, it can be difficult to know if that intervention worked. Supposing last year there was one death there and this year there weren't any; was that because of the design change, or just chance? But we do know that, in aggregate, some relatively constant percentage of collisions will result in deaths, and collisions overall are much more common than deadly ones, so even if the policy goal is to reduce deaths, measuring all collisions is a very useful, less-noisy proxy for determining if an intersection has been made less deadly. So: original author is arguing that we can't meaningfully reason about these things because they're rare, and this commenter is saying "yes we can, if we find a more-common, less-noisy thing that's a good proxy for the rarer thing," and proposes that nuclear close calls are such a proxy.
panax 5y ago
While it is difficult/impossible to accurately quantify the probability of war, and that the ground truth is far more complex than these simple models, there still has been a long list of historical incidents in which the outcome was decided by sometimes random and even independent factors outside of anyone's control and makes the gambler's ruin argument compelling: https://en.wikipedia.org/wiki/List_of_nuclear_close_calls https://en.wikipedia.org/wiki/List_of_nuclear_close_calls https://en.wikipedia.org/wiki/List_of_military_nuclear_accidents https://en.wikipedia.org/wiki/List_of_military_nuclear_accid...

  There's two particular incidents that are great examples of this. The '83 false alarm [1], and the 1980 missile silo explosion [2]. In both cases, they were razor-thin near misses. If either accident happened even once more, we absolutely would have either a radiological disaster or accidental nuclear war. It's this sort of thing that makes me think maybe we shouldn't have any nuclear technology at all, the risks are just too high. Climate change is bad, but not as bad as burning our entire planet to the ground in under an hour, then poisoning it forever.

    > If either accident happened even once more, we absolutely would have either a radiological disaster or accidental nuclear war. The Soviet incident sure, but the missile explosion was pretty much as bad as it could have been. You could explode the rocket fuel in every nuclear missile on the planet and you wouldn't get a single nuclear explosion, just scattered chunks of fresh nuclear fuel over a small area, which isn't really a huge deal compared to, for example, an oil pipeline leak.

Every day I wonder if what is happening in Ukraine right now - will turn out to be another invasion of Czechoslovakia 2022 edition written in history books as a missed opportunity to turn the tide as the world watched paralyzed by Putin’s nuclear rattle. Legitimate concern, yes, but here’s the food for thought and mark my words - it is inevitable that very soon Russia’s rhetoric will turn to “economic sanctions are intended to destroy Russia and are an act of war”, along with “supplying Ukrainian resistance is an act of war”, while the nuclear rattle comes out once again in one form or another, like “Russia is forced to respond by arming with nuclear weapons all allied states, such as Iran, Talibistan, North Korea, Venezuela” etc…

What about asking what's the probability that nuclear-powered nation gets an autocratic leader who can decide on his own whether to launch the first strike? I think the current situation most strikingly points to the dangers autocratic governments pose to the whole planet. If people of a nation could vote on whether to start nuclear war I think they would vote no. But a crazy dictator? Not so sure. It should be the law everywhere: No nuclear first strikes. But that can only work if rule of law is the rule. The other great concern is misinformation and ability to keep most of the nation misguided enough to support a war. There should be international law to prevent spread of misinformation that can cause or lengthen wars.

In a sense the dice are rolled constantly. Every time someone monitors a nuclear power’s early warning system there is a risk that system will return a false positive. There is a chance the operator won’t recognize it. There is a chance the geopolitical situation will cause leadership to believe it is a true positive. There is a chance they will choose to launch on warning rather than risk loosing the opportunity at a meaningful counter attack. I agree that it’s probably impossible to estimate the probability, but it is definitely greater than 0. Eventually the dice will come up snake eyes. Hopefully not before we figure out how to stop rolling them.

They’re not modelling the chance of a spontaneous war erupting without cause on day X. Motivated authors just pretend that’s what the models mean because it makes it easy to ridicule. Regarding this — “it’s probably impossible to estimate the probability” - ok - well. I think we have to unpack that a lot! I would say: “we can model the event.” That’s an absolute. (Anyone who disagrees with that statement just does not understand the statement) It does not mean the models are accurate. The model will provide probabilities. How much confidence can we have in the probabilities? Now this is where the difficulty lies. The probability itself will be a low number. And our confidence won’t be very high. That’s automatically creates an opening for any bad faith commentator to say launch an attack. And yet… what’s the alternative? Pretend it cannot be modelled as various commentators in this page (but not you) have done? Pretend that a model with low probabilities or low confidence can be dismissed? The best response (if we agree that nuclear war is a Bad Thing and worth avoiding) is to improve the models, not ignore them - and of course in so doing —- to try and avoid nuclear war.

Barrin92 5y ago
John Kay wrote a good book about this called Radical Uncertainty. It's annoying that there is an increasing tendency to frame what is a purely narrative statement in quantitative terms. As the author points out war is not historically predetermined, at least in any way we could convincingly figure out, and pulling numbers out of thin air only serves the purpose of trying to talk about the future with less uncertainty than is appropriate. Talking about events in terms of probabilities should be reserved for events that are not dominated by 'unknown unknowns'. You can attach a probability to a volcano outbreak, a transaction in an ordinary functioning market, a game of blackjack. That is to say 'small worlds' where outcomes are known, rules well defined and inputs quantified. You can't predict the overthrow a government in 5 years in numerical terms. That doesn't mean you can't talk about it. It's okay to say something is unlikely or very likely, but it makes more sense to explicitly talk about these things in qualitative terms rather than trying to be 'mathy' to make a prediction appear more objective than it is.
ajnin 5y ago
This makes very little sense to me. Nuclear war is not a random event that might happen at any given point with some probability P. It is a decision that is made based on an evolving situation, there are not independent random event you can apply high school math to. Also an event being rare does not mean that it is unlikely. For example a 29th of February is a rare event, if you were to think about it in terms of probabilities, there is about 0.07% of chance for it to occur on any given day. So you would conclude that there is about 1-(1-.0007)^(2*365)=40% chance to occur within 2 years. But it is obviously absurd to think this way, since the next 29th of February will happen in 2024, in less than 2 years, the probability is 100%.
feral 5y ago
May be missing some subtlety, but at a quick read I would respond to this as: - The author has not deeply understood the subjective interpretation of probability, as widely used by bayesians, and applicable to this sort of reasoning - the author, and the sources the author quotes based on a quick read, seem unfamiliar with quanifying uncertainties not just as point estimates, but instead by using a probability distribution, which you can use to easily tell the difference between a mean probability of .5 based on say 5 heads and 5 tails, vs one based on 500 heads and 500 tails. The point that it's often difficult to tell whether a particular probability should be 0.0001 or 0.00001 is a fair one. But overall I don't take much reassurance from this article.

People claiming Russia to be invulnerable miss the real lesson of those conflicts -- the ballance of power. The ballance of power is set against Russia right now, if the West remains strong in its unity and resolve, Russia will collapse.

This makes me chuckle. The Bad Orange Man played the "insane king" role really, really well. Everyone was on their best behaviour until he left office. Peace talks in the Middle East progressed. Russia stayed in their borders. North Korea huffed and puffed and ultimately did nothing. Trade with China became more favorable to the US. It's almost like his foreign policy was effective. To your point: Putin isn't nuts. He's just a really good politician. He's pragmatic and knows the value of being seen as "crazy" and "he might actually launch a nuke".

dontbeevil1992 5y ago

Another issue with this logic is that the probabilities are not independent. Saying that you have probability x of nuclear war every year and so probability (1-x)^n of no nuclear war in n years assumes independence. In fact, if you don't have nuclear war on year 1, I would assume that the reasons for that lead to inferences and correlations that would affect the probability of nuclear war on year 2, possibly making it lower.

LeonB 5y ago
No, that’s not quite right. Measuring “did we have a nuclear war?” is not the input you’d ever want to use there, it’s only one binary digit of information. Instead take info like “did we have events/incidents with a high potential of nuclear war?” If three “Cuban missile crisis” level events happened in year X, then the probability of nuclear war in year x+1 is higher than it was in other years — even though nuclear war didn’t occur in either year. If national leaders make no statements threatening war in year A, then it’s probably safer than year B where there were 100 such threats.
- dontbeevil1992 5y ago
  I might not have said this clearly enough - I'm not saying that conditioning on "did we have a nuclear war" will change the probability to be less. I'm saying that the event "did we have a nuclear war in year n" is not independent from "did we have a nuclear war in year n+1" "n+2", ... because there are shared factors influencing them. Therefore the model of independent probabilities multiplying year over year and seeming to imply that nuclear war is inevitable because (1-p)^n goes to 0 as n grows doesn't make sense mathematically speaking.
  - LeonB 5y ago
    Ok. I think the question that we want to ask from the model is more like: “What is (one minus (What is the chance we have had 0 nuclear wars by year “now plus 70”?)” So if there is a nuclear war in year n+3 (for example) it’s effect on year n+4 is irrelevant as the answer to the question is already “0% chance of no nuclear wars by year 70”. So the angle you’re initially coming from is not quite relevant. We can then turn that a bit though and continue your point — we can rephrase your claim to be like this, for example: “if we have had 0 nuclear wars in the next 69 years, then surely that would lower the probability of a war in year 70.” And to that I’m saying — actually no. Or rather: not necessarily. Or more accurately: not much! The info of “we’ve had no nuclear wars in 69 years” is not what the model would care about. More likely it would care about, running the model a bunch of times, in the cases where there no wars in the first 69 years, how many times is there a war in the 70th year? And “brink of war” or “HPI” scenarios would be a much better indicator than the simple absense of nuclear war in those first 69 years. Maybe better to said “there is a lot more information in the question of ‘how many times have we been on the brink of war’ than there is in the answer ‘did we have a nuclear war yet? No’. It’s more about that “how much info is there here?”

A useful metric - how often does a national leader willing to start a nuclear war come to power in a state with nuclear weapons? That's measureable from historical data.

jeremyjh 5y ago
Which data would that be? We don't know if anyone is willing to use nuclear weapons against a nuclear power because no one has ever done it.
daliusd 5y ago
How? We had no nuclear war yet. How can you know that leader is willing to?
AnonCoward4 5y ago
It's not measureable. First of you need to account for many having the same weapons (MAD) and you also need to account for the knowledge of the impact of these weapons. The knowledge does change the probability for someone willing and able to use these weapons to come into power (as well as the whole structure around the usage).
vkou 5y ago
You're missing half the equation. 'Every'[0] national leader is willing to start a nuclear war given some particular set of circumstances. There's always some line that they will not allow their enemies to cross. The difference between leaders is what those circumstances are. It's in where that line is. [1] Public communications on this subject have to be taken with a pound of salt. It's in every nuclear nation's interests to claim that line is further out than it really is... As long as they believe that broadcasting the claim itself won't start nuclear war. It's also in every nuclear nation's interests to be very mindful about where their adversary's line is. [0] Okay, there might be a closet pacifist somewhere that won't use them in any situation, but if there is, they certainly aren't broadcasting that. [1] So far, we're batting a thousand for 'No national leader whose last name was not Truman started a nuclear war in a situation where his state was not fighting an existential war'. This statistic, unfortunately, is not particularly helpful.

So this is basically saying that it's extremely hard to estimate these tail-event probabilities reliably, and therefore conclusions should not be taken as gospel. But we mostly knew that already?

hankchinaski 5y ago

the gambler's ruin fallacy is a typical example of cumulative probability. cumulative probability measures the odds of two, three, or more events happening. there's just one catch involved: each event needs to be independent of the others. you can't have the outcome of a first event influence the probability of the next. which we know for nuclear war it be dependent upon the probability of previous events. ie. if a nuclear war starts, either everyone gets annihilated, which in turn influences the probability of the next nuclear war to be zero, or one or both of nuclear powers get severely damaged with catastrophic consequences, therefore influencing probability of future similar events

bayesianbot 5y ago

On the other hand we have a lot of data points of humans and nations using every available edge to expand their power throughout history. Also we have made social systems where narcissistic greed and lust for power seems to get pretty much rewarded with more money and power, and misinformation runs rampant. More powerful weapons systems will get developed until MAD might not be certainty for the aggressor, if bombs can be delivered stealthily in minutes. Or at least MAD might get tested with one warning shot, delivering a message of "what is your actual defense going to be, I don't really care about the world anyways" I don't really see it as much as daily roll of a dice but more of a system that might guarantee to force us down that road some day within a few generations.

empressplay 5y ago
People think MAD is 'we launch everything at our enemy if we see one missile' -- this hasn't been the case for decades, since all sides can see launches almost as soon as they happen. So yes, 'warning shots' are now effectively the start of such a conflict. Where MAD comes in is it's generally accepted that if you do that your opponent is likely to lob one back. An eye for an eye. I suspect capitals of nuclear powers are special cases though, and would generally be avoided unless absolutely necessary. I don't think Putin needs to actually start nuking European countries to get his way though. He knows the Americans simply do not have the resolve to escalate a nuclear confrontation unless its own domestic security is threatened. I don't think the UK or France would either. NATO is kind of a sham. But Putin isn't worried about nukes in Ukraine as much as ground troops. The fact that he is suggests he's not worried about getting nuked himself, which is actually a positive sign, for everyone except Ukraine. ETA: I just realized in Biden's SOTU he said the US would defend every inch of NATO territory and make the Russians pay, which was clever, since neither of those statements suggests either an invasion of Russia nor a nuclear response, only that Russia wouldn't be able to hold the territory and that there would be repercussions of some kind. Not a dumb guy.

> Put differently, Putin does not roll a dice every morning and launches a nuclear missile if a six shows up. Even he himself cannot meaningfully answer the question “What’s the probability that Russia will launch nuclear missiles 6 months from now” unless his answer is 100%. It depends on many factors, like how NATO reacts and how strong the Ukraine military is, none of which can be captured by probabilities. There's a guy[0] who spent a career analyzing and writing about these things. His most recent take is that by refusing to get directly involved in Ukraine, NATO creates an understanding in Putin's mind that it wouldn't get involved in, say, Latvia either. According to Piontkovsky, (to Putin,) there's no essential difference, and the (lack of) NATO membership reason provided by NATO is a lame excuse indicative of a lack of resolve to commit, NATO member or not. So Putin is willing to keep upping the ante until NATO folds and becomes irrelevant.

virgilp 5y ago
I don't buy this. The NATO message was clear & consistent that they will intervene in case of an attack on a member - there's 0 reason to believe otherwise. In fact, I'd say that current response in Ukraine enforces this (though it's not a NATO member it got plenty of offensive equipment, intelligence, money, support, etc. - basically everything possible short of direct declaration of war / direct military involvement from all NATO members). Keep in mind that Putin's mythos was blown to pieces, there's no way he can (politically, if not physically) survive this. And he probably knows it. This is the weakest position he can be in - if the west attacked him, he could at least mobilize the Russians to "defend against western aggression" and could even justify the nuclear bombs to his generals; As things stand, his rhetoric and position are very shaky (he's not being defeated by mighty USA, but by the "weak" Ukrainians who "aren't even a nation")

> Putin does not roll a dice every morning and launches a nuclear missile if a six shows up Very true. Using, essentially, the infinite typing monkeys idea to say that a nuclear war is bound to happen eventually is just a pseudo-scientific rationalization of war. Put this way, almost anything becomes certain if you completely ignore the fact that you don’t know P(nukes|war) since we have no further data to base this on. Even a coin flipped once or twice might not be heads and tails. The idea of P(heads) = 0.5 is that eventually, as the flips extend to infinity, it equals 0.5. This would be similar to someone living in the Black Plague saying “since 10% of Europe is dying per year, in 10 years we will most certainly be extinct.” I don’t know the technical or formal name for this fallacy or line of thinking, so I’ll just call this gross oversimplification.

That’s not how the modelling works. That’s a mischaracterisation, a straw man argument.

hashimotonomora 5y ago

What is an ensemble probability of something that has never occurred and is essentially impossible to model? Have you seen all infinite alternate universes? Probability does not make sense. Compare the following: What is the probability that you will die today? What is the probability that you will die today given that you belong to the category of people with A_i characteristics and whose ensemble probability of dying on a given day has been measured?

LeonB 5y ago
The insurance industry does a pretty good job of “what is the probability that you will die in the next billable period” - but they would never reduce the bet to “what is the probability that you will die today?” You say it’s “essentially impossible to model” something that hasn’t occurred before. Nations have engaged in a lot of wars. Nations have engaged in a lot of wars they could not possibly win. People have committed suicide to harm other people. Many many times. Nations have developed weapons and then used those weapons on other people. Countries that have engaged in arms races and stock piled weapons have then gone to war. Many times. In some decades we do more of these things and in others we do less. To say it’s hard to model, or the models are imperfect (as all models are) - fine. To say it is impossible to model - that’s very naive.
- hashimotonomora 5y ago
  If you are lost in a city would you rather have the wrong map or no map at all? The person that has the wrong map and thinks that it’s the right map is the one that’s naive. Regarding insurance companies, you are conflating ensemble probabilities with time probabilities. Insurance companies can estimate the ensemble probability of an event in a group of agents which belong to a certain category and not the time probability of said event on a single agent.
  - LeonB 5y ago
    I’m pretty sure we’re in agreement in the insurance policy part. If I buy a policy to cover my risk of death for the next X years, the insurance company uses the ensemble probability of the group to price that policy (and believes that the risk of me knowing more than them is covered by the fact they’ve factored that in, plus that they’ve insured multiple people in the group and the aggregate will be good even if 1 policy isn’t.) If I said to an insurance company — okay I want to buy a policy that only covers me for one day - they would not do it. Firstly of course the transaction costs would swamp the cost of the policy, but let’s ignore that by pretending they use some magical technological solution (digital contracts… hardy har har) The second reason they wouldn’t do it is because that’s not how their model works. It has to smooth over time. Over a year, over a lifetime - not over a day. The third reason they wouldn’t do it is because the information asymmetry now dominates. My knowledge of whether I’ll die tomorrow in particular is better than their model. I’m able to price the policy much more accurately than them. The fact I want the policy is a big red flag. (They do offer some very short term contracts such as holiday insurance — but those disclaim every imaginable pre-existing… which is out of scope for this discussion as it’s not something we can do with nuclear risk) I think we more or less agree on that stuff. Don’t we? What I’m saying about it is that just as we all know that insurance policies don’t make sense when you reduce it down to thinking about an individual person on an individual day — the nuclear war modelling doesn’t work when (the author of the article) reduces it down to saying it’s like suggesting that Putin flips a coin each morning. The most likely reason an author would pretend that the models claim such a plainly ridiculous thing is in order to ridicule the models, about a claim they did not make. In this way it is a straw man argument. They are recasting the original assertion into something that is easy to attack. It’s not a well intentioned thing to do. That’s what I’m saying about that.

LeonB 5y ago

In safety we try to prevent rare events (such as death) and these are rare enough that “past deaths” are not a useful way to predict the likelihood of a death. A crucial metric that occurs more more often and does help predict deaths is “HPI” - high potential incident. A worker eight metres in the air dropped a spanner. It thudded on the ground, harmlessly. No one was hurt. No problem, right? That’s a HPI. A workplace that has a death will have had many HPIs. The dice-roll is not “it’s a new day, we roll the dice”. When a HPI occurs, that’s when we roll the dice. Or in nuclear war estimates: a HPNWI occurs (high potential nuclear war incident). The Cuban missile crisis springs to mind as a particularly big example. But many many smaller HPNWI’s have occurred. Border skirmishes between nuclear powers. Sabre rattling by nuclear powers. Elect a president who uses threats and brinkmanship. Do this year in, year out. The dice is rolled not because time passes but because risky decisions are made and risky actions are taken, over and over and over and over and over and over, year in, year out.

- apendleton 5y ago
  I took it to be: the original author's point was that nuclear attacks are so rare and our sample size so small that we can't use history to predict their occurrence in the future. This commenter is saying the typical way to handle situations like this is to look for more-common events that are proxies for the less-common ones in some predictable way. To give a different example of my own: on an intersection-by-intersection basis, pedestrians dying from getting hit by a car is relatively rare, so if it's perceived that a particular intersection is unsafe and the design of the intersection is modified with a goal of reducing the chance of death, it can be difficult to know if that intervention worked. Supposing last year there was one death there and this year there weren't any; was that because of the design change, or just chance? But we do know that, in aggregate, some relatively constant percentage of collisions will result in deaths, and collisions overall are much more common than deadly ones, so even if the policy goal is to reduce deaths, measuring all collisions is a very useful, less-noisy proxy for determining if an intersection has been made less deadly. So: original author is arguing that we can't meaningfully reason about these things because they're rare, and this commenter is saying "yes we can, if we find a more-common, less-noisy thing that's a good proxy for the rarer thing," and proposes that nuclear close calls are such a proxy.

You could explode the rocket fuel in every nuclear missile on the planet and you wouldn't get a single nuclear explosion, just scattered chunks of fresh nuclear fuel over a small area, which isn't really a huge deal compared to, for example, an oil pipeline leak.

  I think nuclear energy is mostly orthogonal to nuclear weapons. We should pursue more nuclear energy and seek to eliminate nuclear weapons.

Every day I wonder if what is happening in Ukraine right now - will turn out to be another invasion of Czechoslovakia 2022 edition written in history books as a missed opportunity to turn the tide as the world watched paralyzed by Putin’s nuclear rattle. Legitimate concern, yes, but here’s the food for thought and mark my words - it is inevitable that very soon Russia’s rhetoric will turn to “economic sanctions are intended to destroy Russia and are an act of war”, along with “supplying Ukrainian resistance is an act of war”, while the nuclear rattle comes out once again in one form or another, like “Russia is forced to respond by arming with nuclear weapons all allied states, such as Iran, Talibistan, North Korea, Venezuela” etc…

what is Talibistan?
- klausjensen 5y ago
  I believe the author refers to Afghanistan under the rule of Taliban...
  - VincentEvans 5y ago
    Yeah, I started typing it out, but then took the shortcut figuring people will get that from the context.
  - cdelsolar 5y ago
    but Afghanistan under the Taliban is certainly not an allied state of Russia...
    - VincentEvans 5y ago
      I don’t think I would be saying something scandalous and shocking by pointing out that for Russia - enemy of my enemy is… if not a friend, then an associate at the least, and theres nothing that’s seems outside of ethics for Putin’s regime.

What about asking what's the probability that nuclear-powered nation gets an autocratic leader who can decide on his own whether to launch the first strike? I think the current situation most strikingly points to the dangers autocratic governments pose to the whole planet. If people of a nation could vote on whether to start nuclear war I think they would vote no. But a crazy dictator? Not so sure. It should be the law everywhere: No nuclear first strikes. But that can only work if rule of law is the rule. The other great concern is misinformation and ability to keep most of the nation misguided enough to support a war. There should be international law to prevent spread of misinformation that can cause or lengthen wars.

In a sense the dice are rolled constantly. Every time someone monitors a nuclear power’s early warning system there is a risk that system will return a false positive. There is a chance the operator won’t recognize it. There is a chance the geopolitical situation will cause leadership to believe it is a true positive. There is a chance they will choose to launch on warning rather than risk loosing the opportunity at a meaningful counter attack. I agree that it’s probably impossible to estimate the probability, but it is definitely greater than 0. Eventually the dice will come up snake eyes. Hopefully not before we figure out how to stop rolling them.

The original article does this straw man trick of pretending that the models act like every day is independent. That’s not how it works at all. They’re not modelling the chance of a spontaneous war erupting without cause on day X. Motivated authors just pretend that’s what the models mean because it makes it easy to ridicule. Regarding this — “it’s probably impossible to estimate the probability” - ok - well. I think we have to unpack that a lot! I would say: “we can model the event.” That’s an absolute. (Anyone who disagrees with that statement just does not understand the statement) It does not mean the models are accurate. The model will provide probabilities. How much confidence can we have in the probabilities? Now this is where the difficulty lies. The probability itself will be a low number. And our confidence won’t be very high. That’s automatically creates an opening for any bad faith commentator to say launch an attack. And yet… what’s the alternative? Pretend it cannot be modelled as various commentators in this page (but not you) have done? Pretend that a model with low probabilities or low confidence can be dismissed? The best response (if we agree that nuclear war is a Bad Thing and worth avoiding) is to improve the models, not ignore them - and of course in so doing —- to try and avoid nuclear war.

Good piece. Typo in the last line: It's "stave off", not "stage off".

John Kay wrote a good book about this called Radical Uncertainty. It's annoying that there is an increasing tendency to frame what is a purely narrative statement in quantitative terms. As the author points out war is not historically predetermined, at least in any way we could convincingly figure out, and pulling numbers out of thin air only serves the purpose of trying to talk about the future with less uncertainty than is appropriate. Talking about events in terms of probabilities should be reserved for events that are not dominated by 'unknown unknowns'. You can attach a probability to a volcano outbreak, a transaction in an ordinary functioning market, a game of blackjack. That is to say 'small worlds' where outcomes are known, rules well defined and inputs quantified. You can't predict the overthrow a government in 5 years in numerical terms. That doesn't mean you can't talk about it. It's okay to say something is unlikely or very likely, but it makes more sense to explicitly talk about these things in qualitative terms rather than trying to be 'mathy' to make a prediction appear more objective than it is.

This makes very little sense to me. Nuclear war is not a random event that might happen at any given point with some probability P. It is a decision that is made based on an evolving situation, there are not independent random event you can apply high school math to. Also an event being rare does not mean that it is unlikely. For example a 29th of February is a rare event, if you were to think about it in terms of probabilities, there is about 0.07% of chance for it to occur on any given day. So you would conclude that there is about 1-(1-.0007)^(2*365)=40% chance to occur within 2 years. But it is obviously absurd to think this way, since the next 29th of February will happen in 2024, in less than 2 years, the probability is 100%.

May be missing some subtlety, but at a quick read I would respond to this as: - The author has not deeply understood the subjective interpretation of probability, as widely used by bayesians, and applicable to this sort of reasoning - the author, and the sources the author quotes based on a quick read, seem unfamiliar with quanifying uncertainties not just as point estimates, but instead by using a probability distribution, which you can use to easily tell the difference between a mean probability of .5 based on say 5 heads and 5 tails, vs one based on 500 heads and 500 tails. The point that it's often difficult to tell whether a particular probability should be 0.0001 or 0.00001 is a fair one. But overall I don't take much reassurance from this article.
