"Even though he could foresee the problem then, we can see it equally well now. Therefore, if he could foresee the solution then, we should be able to see it now. After all, Seldon was not a magician. There are no trick methods of escaping a dilemma that he can see and we can't."
-- Salvor Hardin
Years ago at the Singularity Institute, the Board was entertaining a proposal to expand somewhat. I wasn't sure our funding was able to support the expansion, so I insisted that - if we started running out of money - we decide in advance who got fired and what got shut down, in what order.
Even over the electronic aether, you could hear the uncomfortable silence.
"Why can't we decide that at the time, if the worst happens?" they said, or something along those lines.
"For the same reason that when you're buying a stock you think will go up, you decide how far it has to decline before it means you were wrong," I said, or something along those lines; this being far back enough in time that I would still have used stock-trading in a rationality example. "If we can make that decision during a crisis, we ought to be able to make it now. And if I can't trust that we can make this decision in a crisis, I can't trust this to go forward."
People are really, really reluctant to plan in advance for the abyss. But what good reason is there not to? How can you be worse off from knowing in advance what you'll do in the worse cases?
I have been trying fairly hard to keep my mouth shut about the current economic crisis. But still -
Why didn't various governments create and publish a plan for what they would do in the event of various forms of financial collapse, before it actually happened?
Never mind hindsight on the real-estate bubble - there are lots of things that could potentially trigger financial catastrophes. I'm willing to bet the American government knows what it will do in terms of immediate rescue operations if an atomic bomb goes off in San Francisco. But if the US government had any advance idea of under which circumstances it would nationalize Fannie Mae or guarantee Bear Stearns's counterparties, this plan was not very much in evidence as various government officials gave every appearance of trying to figure everything out on the fly.
A published, believable advance plan for the worst case - one that you could actually believe the government would carry out, instead of junking the plan to try to keep the top spinning a little longer - would have made the markets that much less uncertain.
If you don't publish a plan for catastrophe - or can't publish a believable plan - then the market just tries to guess what a realistic, believable plan would look like. If that realistic, believable plan involves frantically attempting to bail out the large financial entities in order to keep the whole system from melting down further, you have moral hazard. If they actually do it, that's lemon socialism (privatized upside, public downside).
If that's what happens in the abyssal case - then not publishing that fact, doesn't prevent anyone from foreseeing it. If you publish that plan, maybe it will start a debate about whether to break up Bear Stearns into smaller entities, or change the plan to give counterparties a predictable 10% haircut, or claw back executive bonuses no matter what their contracts read (because you really aren't supposed to screw up so badly that the government has to get involved)...
But if you can't publish a realistic, believable advance abyssal plan that doesn't call for rescuing the huge entities - then who are you even kidding?
Governmental agencies failing to stare into the abyss in advance gives us a double problem: moral hazard as counterparties and investors try to guess what the government will realistically do; and fear and uncertainty in the market when the worst does happen.
It's questionable whether the government should be in the position of trying to forecast the abyss - to put a probability on financial meltdown in any given year due to any given cause. But advance abyssal planning isn't about the probability, as it would be in investing. It's about the possibility. If you can realistically imagine global financial meltdowns of various types being possible, there's no excuse for not war-gaming them. If your brain doesn't literally cease to exist upon facing systemic meltdowns at the time, you ought to be able to imagine plausible systemic meltdowns in advance.
Sure, you might have to make some modifications on-the-fly because you didn't get the exact causes and circumstances right. But it shouldn't be obvious and predictable that the modifications will consist of "Oh dear it's more awful than we planned for and the systemic hazard is worse and now we really do have to bail out everyone even though we said we wouldn't." Then the plan is not believable.
So long as the plan is not wrong in the stupidly obvious directions, it's hard to see how we'd be worse off if the governors of the Federal Reserve had taken a week once per year to play through scenarios more nightmarish than this one in their minds, deciding in advance what to do about it, realistically.
I suppose the main argument against publishing the plan would be that the uninformed public (i.e. Congress) would revolt against the emergency plans, demanding that unbelievable plans be substituted (let the banks burn! don't bail out GM!) and then changing their tune as soon as the worst actually happened.
But at least having the Federal Reserve privately visualizing all sorts of hideous possibilities in advance, war-gaming them with the Board of Governors, and planning for them realistically - so that when the worst starts happening, you don't have everyone running around being vague and visibly unprepared and refusing to talk about what happens if things get even worse - instead you just take out folder #37-B and figure out what needs tweaking - for the lack of that preparedness, there seems to me to be very little excuse. The Federal Reserve should not be in the business of forecasting probabilities - they've already demonstrated that they can't, and they're not investors. They should just be always staring into the abyss.
Of course the Federal Reserve doesn't read this blog, so far as I know. But it's the sort of thing that doesn't require a majority vote for individuals to use in their personal lives.

There is a vast space of possible things that can go wrong, so each plan will have to cover a pretty wide range of scenarios. Even to include a scenario as one with a plan will signal to viewers that you consider it more likely and/or important.

I doubt we'd find much comfort in the government's plans for an A-bomb in San Fran, and probably much less in their execution.

Robin, there are many possible causes but the convergent results of systemic risk, asset price declines, deleveraging, slows in money velocity, etc. etc. might not be that different across causes. Would Bear Stearns have gone much differently, if an atom bomb had gone off in San Francisco? Staring into one abyss would increase your ability to deal with many others without panicking.
Burger, comfort isn't the point. You can't expect to suddenly find a trick method in the actual event, so whatever uncomfortable thing it is you're going to end up doing, why not know it in advance?

Isn't there a bias something like: "If something actually happens, then people believe that it was foreseeable before it happened."?
I think you're correct (and also) governments should be judged more by how well they protect against extreme circumstances than how well they do in the no-disaster, short term.
However, an opponent of your ideas might make an argument that if they believed the probabilities of collapse implied by the market before the collapse, it would have been a waste of time and effort to make plans for such worst-case scenarios.

Here's a sick idea.
Call for volunteers. Ask people to volunteer for positions in that list, first-come, first-serve. The first to volunteer are the last to be fired if money becomes short.
When money becomes short, flip a coin, and if it comes up heads - reverse the list. Now the first to volunteer will be the first to be fired.
This reconciles the fundamental issue that those who rush to volunteer if they will be the LAST fired are probably those with the least confidence in the project. The coin toss roughly equalises the chance that anyone on the team will be fired, based on their position in the list, leaving them all roughly equivalent in terms of their motivation to keep the project running.
I don't know what good that is in the grand scheme of things, I just thought it made things interesting.

In "David's Sling", Marc Stiegler suggested that even just visualizing in advance what could go wrong would be helpful, in that if the worst happened you at least wouldn't be fighting disbelief as well as trying to make things work.
And does anyone think that the gov't would actually keep to a plan with special interests screaming for help. It's the same problem of trusting gov't; Congress can change any law any time it wants, you cannot rely on what they have said, or even what they have enacted into law.

"Why didn't various governments create and publish a plan for what they would do in the event of various forms of financial collapse, before it actually happened?"
Same reason the money that was supposed to go to flood control in New Orleans got spent on more-visible projects. What politicians do is get elected, not solve people's problems. How would devoting energy to this sort of plan win votes? The sort of person who would even consider this sort of thing wouldn't be running for office and wouldn't get campaign contributions if they did.

Hardly any potential catastrophies actually occur. If you only plan for the ones that actually occur (say, by waiting until they happen, or by flawlessly predicting the future), then you save a lot of mental effort.
Also, consider the difference between potential and actual catastrophe regarding how willing you will be to make a desperate effort to find the best solution.
comment by Doug_S. · 2009-02-23T23:19:09.000Z · LW(p) · GW(p)
What if, realistically, your plan turns out to be "Do nothing of consequence, and let my successor deal with the mess?" You probably don't want to actually tell people that, even if that's the way the incentives turn out. (For example, my father works for a company that recently fired its CEO, after some decisions he made turned out to be disastrous. Unfortunately, according to the CEO's contract, they had to give him a huge severance package if they fired him. Ergo: the company is screwed, but he isn't.)
comment by Hrm · 2009-02-24T00:05:24.000Z · LW(p) · GW(p)
There are number reasons:
1) Economics, being the dismal science, has been very bad at prediction. Sometimes, some schools get stuff right, other times they get them dead wrong.
2) Due to the huge number of variables, it's hard to even make a plan
3) With Economics, what worked last time may not in fact work this time. Economics is not like Physics. Sometimes it /seems/ deterministic, other times it doesn't. It's also very difficult to test in a "lab-like" setting. There's no such thing as a clean-room country that you can test your theories on without outside influence.
4) Finally, we have the issue of the dominant economic ideology, Neoliberalism, close cousin of perennial favorite Economic Libertarianism that insists that process legitimizes outcome. Why mess with anything if it was /supposed/ to happen as a result of market forces? It may even be fair (but it makes a lot of people miserable). That's OK, though, since it's proper adjustment.
comment by SilasBarta · 2009-02-24T01:05:37.000Z · LW(p) · GW(p)
Correct me if I'm wrong, but wasn't the problem that the government's economic "experts" seriously believed that the worst possible thing that could happen was that the system needed a "liquidity" injection?
Well, now the major institutions are clamoring for "liquidity", but that has by now become a euphemism for "free money in the form of a loan that no sane person expects to be paid back."

I'm with Doug S. on this one. None of the "leaders" who be in a position to create such plans are in any way motivated to develop or publish such things, or to follow them after the fact.
For those that ARE interested and motivated to make such things, a better term would be "prediction" than "plan". And we're very bad at such predictions, as we always seem to underestimate the shortsightness of every participant, from government to private industry.

If any of you guys have any suggestions you may get one more to your camp as this blog has whet my appetite for rationality. Thanks in advance to any with some thoughts.

They can't publish such a plan because it would depend almost entirely on who was in power. In the US specifically, also because no executive has any incentive to plan for anything at all beyond their 8th year.

Hmm. It seems to me that Eliezer had a plan for the economic crisis, namely to keep his mouth shut about it, and when the crisis actually happened the pressure to talk about it apparently exceeded his expectations and he didn't follow through. That with the level of agency and unitary identity of a practiced human rationalist. Imagine how much less able to follow through he would be if he fell entirely under the sway of an arbitrary coalition of sub-motivations every 4 years (hmm... he does deny identity with the authors of his earlier papers). Oh, and I have to ditto "Katrina".

Original draft of this post contained the specific reasons I was trying to keep my mouth shut (everyone already talking, and seems like the sort of thing a non-professional would screw up) to which this post is a probable exception (haven't seen it pointed out, and the interaction with domain-specific expertise that makes everything I said about the psychology obviously wrong is at least not visible at a glance). Deleted because it wasn't really all that relevant.

Johnicholas:

Hindsight Bias and, to an extent, Taleb's Narrative Fallacy. This whole topic is quite Talebian. How do we plan for disasters we can't foresee? As Robin says,
There is a vast space of possible things that can go wrong, so each plan will have to cover a pretty wide range of scenarios.
While there might be a very wide range of causes for disasters, the possible effects are likely to be fewer. A government can plan for a crisis by making a shortlist of bad things and planning how to limit their effect, and can deal with the underlying cause on-the-fly. By analogy to emergency medicine, deal with easy-to-see life-threatening symptoms first and figure out the underlying cause later when the patient is stablised. In financial disaster planning, decide how to deal with known knowns like high unemployment, high interest rates, inflation and so on beforehand then figure out how to deal with the failing banks as you go along.

My impolite assumption is that you want to discuss having plans for when things go abyssal, but I don't think the current economical turbulence is a good example. What's happening is natural, a reaction to mindless tampering. What would that plan look like? "If we tamper too much, lets tamper some more in THIS way instead". The thought of stop tampering will not occur to them.
The underlying problem is that the ones in charge don't understand human nature. They they don't understand people, they don't understand themselves, and think economics is something unrelated to what makes people people tick. In a couple hundred years, I believe current economic theories will be regarded they same way as alchemy. If things doesn't go abyssal before then.(Is it not depressing to go around thinking like this all the time?)
I guess people prefer to think about how to make the worst case not happen rather than plan what to do when/if they get there. What are the possible bad outcomes, what lies outside our control and how can we minimize the risk. Emergency plans are good for things we have little control over, like natural disasters(disregarding that they can avoid building huge cities at stupid locations, and subsidize rebuilding them when they are wiped out). People like to think they understand economics and therefor can control it. Problem is that reality doesn't fit their model.
Oh, and I don't claim to have anything close to a complete understanding of people. But you don't need to understand everything to see that someone else doesn't get it either.

This may provide some insight on the topic:
Politico: Yap trap: Pols talk, markets dive 2/24/09 It was a perfectly reasonable question, and on the surface it seemed like a perfectly reasonable answer. But when Senate Banking Committee Chairman Chris Dodd went on Bloomberg TV Friday and mused about the possibility of bank nationalization, panicked investors sent the Dow plummeting a hundred points in the next hour. Whoops. Dodd’s casual remark and the not-so-casual consequences it caused were among the most vivid examples of a new Washington phenomenon. The city’s sudden status as the de facto world financial capital means that briefings and interviews that once would have passed with a yawn can create instant terror on Wall Street and Main Street alike. [...] “Sen. Dodd’s ‘nationalization’ comment wins the Oscar for most irresponsible remark by a U.S. official,” said Tony Fratto, a financial spokesman at the White House and the Treasury Department during the Bush years. “The last thing markets need is to have officials speculating about hypothetical policy choices.”

I suspect that if you could go back in time and confront the Federal Reserve on their lack of abyssal planning, the knee-jerk justification for it would be very similar to the current justification for Obama's vocal and continual support of the Stimulus package - namely, that the economy works on unquestioning Faith. The Stimulus will work as long as people believe it will work, the math be damned. We can't make an Abyssal Plan because doing so will cause it to manifest.
They seem to think that the economy is a form of Consensus Reality, and nothing more. While you can point to economic bubbles (such as Tech in the 90s, or Tulip Mania in the 1600s) as an example of this, all bubbles share a common feature - eventually cold, hard, deterministic reality came crashing in to lay the smack down.
Refusing to plan for economic abysses seems on par with the driver of a car not asking his passengers to buckle up, because he doesn't want to jinx himself and get into an accident.
While it is true that people hate to think about the abyssal scenario (lord knows, I never do in my own life) there is one branch of government which does a great job of it - the military. I'd wager they even have contingency plans for an intra-NATO war. I see no reason you couldn't find a bunch of Economists who would take a morbid glee in planning for an apocalypse.

When I worked remodeling and landscaping I used to try to visualize what could go wrong and head potential problems off while we were still planning the work. I finally got tired of the man I was working for calling me a pessimist and complaining about my negativity and quit saying anything.
Stay well away from anyone who uses the word "negativity". Every time I have heard it used it was an attack on someone attempting to show some foresight.

Here are some possible reasons for not wanting to explicitly plan for future failure, more at the level of the institute than at the level of the economy:
-The board wants to build consensus and forge a diverse group of people into a coherent whole. Telling some people that they are marginal would damage this focus.
-If a funding agency finds out that you can withstand an X% cut with vital operations intact, your odds of getting your grant cut by X% skyrocket.
-The board and officers are largely tasked with selling your concept to funding agencies. Given that funding agencies are usually risk-averse in practice (despite being risk-seeking in rhetoric), any suggestion that you might fail makes it harder to get funding.
You are making a conscious effort not to fool yourself. This habit of mind is excellent in a scientist or philosopher, but does not work well in contexts involving leadership, salesmanship, and negotiation.

I don’t suppose you can. But the process of deciding in advance can cause a lot of trouble. It would be necessary for people to argue in favour of e.g. firing Eliezer Yudkowsky first, rather than anybody else. Then you might have to work with the person who made that argument. Perhaps after arguing that he should be fired first, instead.
Perhaps it would have been easier to decide in advance that everyone should take a pay cut...
Short version: People try to avoid hard choices because they are hard. If the choice will not have to be implemented for a long time, if ever, there is therefore a lot of pressure to defer making the choice. After all, if you defer it long enough, you might never have to make it at all.
comment by Mike6 · 2009-02-24T19:49:54.000Z · LW(p) · GW(p)
I think the answer is, beforehand there are too many contingencies and it seems like a waste in mental effort to consider them all.
Consider the stock example, which is quite simple. I buy a share at $100. I don't think it's so simple that I decide in advance I'm going to sell if it drops below $80. What if, in one day, it drops to $83, and I don't have access to a broker except to sell it at the end of the next day? What if the stock is doing well, and then there's a rumor that quickly sends it down to $80? What if I happen to have good reason to think the rumor is false? What if it's doing very well, but then a rumor sends it down to $85? And this time, I think the rumor is correct. What if I'm away from my broker while bad news develops and it drops to $50, but then the bad news appears increasingly not so bad and the stock is rising when I get in contact with my broker again? Etc.
And all this has to do with when to sell a share of stock, which is seemingly characterized by a single number. There is much more that can develop in connection to the scenario you describe.

For the same reason that when you're buying a stock you think will go up, you decide how far it has to decline before it means you were wrong
Do any investors actually do that? I don't mean to be rude - but why haven't they got better things to do with their time?

But what good reason is there not to? How can you be worse off from knowing in advance what you'll do in the worse cases?
The answer seems trivial: you may have wasted a bunch of time and energy performing calculations relating to what to do in a hypothetical situation that you might never face.
If the calculations can be performed later, then that will often be better - since then more information will be available - and possibly the calculations may not have to be performed at all.
Calculating in advance can be good - if you fear that you may not have time to calculate later - or (obviously) if the calculations affect the choices to be taken now. However, the act of performing calculations has associated time and energy costs - so it is best to use your "calculating" time wisely.

Millenium Challenge. (A defence of it is here for sake of balance).
I'd expect lots of Advance Abyssal plans by government, especially war gaming as Eliezer suggested, to end up something like that. As a hypothetical future it falls more prone to signalling and various biases.

It seems reasonable to me to not come up with fixed solutions to crisis, ahead of time.
I'd propose that it is very difficult to, in general, ahead of time, properly assess the viability of a solution. Planning who to fire ahead of time doesn't make sense for a business, since it is difficult to figure out ahead of time, who will be most likely to be useful or harmful during a crisis. For a world wide crisis, it may be more reasonable to have an arsenal of well thought out, potential solutions, and an ordering for considering them in any situation - assuming it can be done more efficiently than coming up with a solution on the spot.
In the specific case of a political body, this sort of planning faces even more problems. If the government had planned ahead on how to deal with a financial meltdown, the plans would have been heavily influenced by those with political clout, increasing the risk of profiteers getting into the fray, to attempt and abuse any recovery plans. The government has to be competent enough at dealing with planned solutions in general, for the plans to be worth making.

The pain of a crisis is in having to deal with it in the first place. What you are proposing is to deal with a crisis before it occurs, in order to prepare ourselves better for it. This means incurring the pain upfront even though there is a low probability that the crisis will ever occur. Now multiply this by the number of different crises - New Orleans, after all, is different from Bear Sterns - and we might spend all of our spare time preparing for low-likelihood catastrophes.
Perhaps you'll argue that not everyone needs to prepare, only a few people need to do it on everyone's behalf, but I don't think that's true. Preparedness has to be pervasive, or else we're not prepared.

I have been personally doing this for years with really nasty personal scenarios. From broken bones to amputation of limbs to death of family members, etc.
It is liberating, but you have to overcome your initial mental pain reflex. It hurts to imagine a funeral for your significant other, but you need to know what to do in the case: find a good psychologist in advance and know who of your friends you can depend on to make sure you don't get ripped off by an undertaker.
