For those who haven't heard, NIH and NSF are no longer processing grants, leading to many negative downstream effects.

I've been directing my attention elsewhere lately and don't have anything informative to say about this. However, my uninformed intuition is that people who care about effective altruism (research in general, infrastructure development, X-risk mitigation, life-extension...basically everything, actually) or have transhumanist leanings should be very concerned.

The consequences have already been pretty disastrous. To provide just one, immediate example, the article says that the Center for Disease Control and Prevention has shut down. I think that this is almost certain to directly cause a nontrivial number of deaths. Each additional day that this continues could have huge negative impact down the line, perhaps delaying some key future discoveries by years. This event *might* be a small window of opportunity to prevent a lot of harm very cheaply. 

So the question is:

1) Can we do anything to remedy the situation?

2) If so, is it worth doing it? (Opportunity costs, etc)

The consequences have already been pretty disastrous.

Can we please not engage in public hysterics?

Under which definition of disaster have the consequences already been "pretty disastrous"?

6Ishaan10y
I dunno, I think the interrupting of scientific experiments all across the US is pretty disastrous, in terms of long term effects. The positive downstream effects of scientific research should not be underestimated, and a large scale disruption of that seems bad. As I said, I'm not terribly well informed about this. Is there something I'm not considering about the extent of the interruption?
4[anonymous]10y
Here at a major research-focused university, work goes on as if nothing happened for now. There are however possibly going to be snarls in the grant-application process if this goes on for a while and much of my lab's funding does come from the federal government in one way or another, causing further problems in the event of truly long showdowns. I don't know the grant distribution schedule off the top of my head. Luckily we have all our new expensive equipment on hand as of a few months ago and ongoing costs are for things like yeast extract and disposable test tubes and tiny bits of custom DNA. And all our pay, of course... EDIT as of 10-5-13 It would appear that those of us who have grants paid out for multiple years as lump sums from the NIH are doing okay. Those of us who charge things to an external account are having a difficult time. And those of us who get yearly infusions of money and get the infusion in the fall are doing particularly badly. My lab seems to fall in the first two categories, thankfully enough.
0Ishaan10y
So, a lot of people here have been saying that my notion that there is a high probability that this entire thing has had lots of very negative effects (taking into account the exponential returns on research) are hyperbolic and silly. When I read this, I feel like I was right about the negative impact, even if I was wrong about the possibility of effecting the outcome. (My notion was that perhaps labs which were in keen need of small funds to tide them over could be supplemented, perhaps with pay-back-if-you-can loans) I would really like to avoid feeling that I was right if I wasn't actually right, so can I ask after your estimate of how much difficulty these people are in and what the rough ratio of effected / not effected is among those who you observe?
-2ChristianKl10y
It's not like scientists sit around and do nothing when they don't get funds. The might not be able to buy fancy new toys but they can still use their brains. Not having to waste as much time with writting grants is also a plus. They might even start thinking about applications of their knowledge to make money by solving real world problems. It reminds me of Bruce Sterlings book Distraction.
5Ishaan10y
Sure. Those who can pick up where they left off are not going to even notice that this happening. But there are a lot of projects that are very time sensitive, which have already had a lot of money and labor invested into them. These which might be significantly delayed or even cancelled, resulting in a loss of invested resources.
0Douglas_Knight10y
Could you give an example of such a project? I doubt that any projects will be canceled because of the shutdown.

From the linked article:

if the NSF misses one or two weekly payments to the National Radio Astronomy Observatory in Charlottesville, Virginia, the facility would be forced to close, disrupting long-term research, says facility director Tony Beasley.

also

At NASA, one casualty could be the Mars Atmosphere and Volatile Evolution (MAVEN) mission, which until 1 October was being prepared at Cape Canaveral in Florida for an 18 November launch. MAVEN’s principal investigator, Bruce Jakosky of the University of Colorado Boulder, says that his team can accommodate a brief work stoppage. But if MAVEN, which will study the Martian atmosphere, misses its three-week launch window, it will be delayed until 2016,

(A 3 year wait for something that was going to launch next month probably means wasted resources. There's also a chance that it becomes a sunk cost as better tech. comes by.)

the FDA has put 45% of its staff on leave and will cut back on food-safety programmes

Given the number of programs being effected, I think it's really unlikely that no projects will be shut down anywhere because of this.

2NancyLebovitz10y
I'm more worried about biology experiments-- some of them need constant maintenance. Do you know whether the folks who are feeding the animals and such are still doing so?
4[anonymous]10y
I did hear about this. Yes, those people were generally considered essential, so they get to work. Article link that mentions this: http://www.npr.org/blogs/thetwo-way/2013/10/01/228208246/the-shutdown-s-squeeze-on-science-and-health
2NancyLebovitz10y
I just heard a radio report which said that animals are being taken care of, but the results of experiments aren't being collected.
3A1987dM10y
Sure they can; but how many of them will be willing to?
0ChristianKl10y
What do you think they are going to do? Spend their time learning cooking and taking long naps?
4A1987dM10y
Don't think about the first scientist you can think of, think about the marginal scientist.
1ChristianKl10y
I think you underrate the value of unsheduled time when it comes to coming up with new creative ideas.
7A1987dM10y
I don't -- for the typical scientist. But there are a few marginal scientists out there who are torn between keeping on doing research and quitting science to take up (say) surfing, and will pick the latter but would pick the former if counterfactually the NSF were still processing grants.
2Eugine_Nier10y
Yes, but how much would they have contributed to science had they not quit science?
-1[anonymous]10y
Actually, no. A federally-employed scientist can't "still use their brains" during a shutdown; see the Antideficiency Act. See above. Grants have to be written eventually; not being able to work part of the year just makes the proportion of working time that has to be devoted to writing grants larger.
1JoshuaZ10y
Huh? How does this stop them from using their brains? Nothing there is going to stop them from continuing to think about their work, mentally desigining new experiments or new hypotheses.
2[anonymous]10y
Admittedly no one's ever been charged under the ADA, but there are plenty of examples of people being disciplined for violating it. I've been temporarily laid-off before -- they're not joking about not being allowed to work. At all. Even granting that our hypothetical scientist is willing to take the risk of being admonished for working during shutdown -- what exactly are they going to do without institutional support? No journal access, no computing resources, no facilities? Navel gazing only gets one so far.
2SilasBarta10y
Thinking about your experiments does not (in itself) involve expenditure of government money, so I don't see how they would prosecute you under the ADA for that. Yes, managers have to be very clear to workers not to use resources, just to keep them away from edge cases, but even with that level of overcaution, managers can't actually stop you. Even if you came back and (for some reason) said, "Hey boss, I totally thought about this experiment from the couch when the shutdown was going on", they still don't have grounds unless you were using up resources. Now, they could fire you just for the defiance (maybe), but if they're that trigger-happy in the first place, then ...
0JQuinton10y
How effective is the thinking that can be done if you don't have access to any of your work? I'm a gov't employee and am affected by the shutdown. All of my work is on my office computer, which I'm not allowed to even turn on during the shutdown. Yes, it's illegal for me to turn on my work computer or access work email during the shutdown. Sure, I can think all day about how to solve the current bug in my software, but without access to the actual code on my gov't computer not much can be done.
0Luke_A_Somers10y
I worked out an algorithm on paper while I was on vacation once. Once I was back, I implemented it quickly.
2JoshuaZ10y
This doesn't seem to be that severe a grant. People go into science because they like it, not because it pays well.- for many, thoughts fields about one's subject can border on the intrusive. And as long as they come back and don't say explicitly that their new ideas were from when they were on leave, they'll be fine. So, they can read papers they already have. They can get journal access from friends at universities. They can do computing that doesn't involve as large a scale. They can think about data they got that doesn't seem to make sense. I agree there are limits but those limits seem not that restrictive as long as the shutdown doesn't last for that long.

public hysterics?

...

has shut down on 18 occasions

Is that why you thought I was doing public histerics? I am uninformed, but that much I did know. Just because something has been happening doesn't mean it's okay to let it keep happening.

I'm not implying that society will collapse. I'm saying that research has exponential returns, and as a consequence setbacks that seem small right now might actually be pretty bad. Each one of these 18 occasions could have potentially set us back several years.

I posted to get an estimate on how bad this damage is, and how preventable it is. It might be a stupid question to someone who knows what's going on, but I really don't understand the hostility towards the fact that it was asked.

8ChristianKl10y
Politics is the mind killer. If you happen to be cluless about a charged political issue you shouldn't be suprised when you encouter hostility when you talk about the issue. If you want to get an accurate estimate it's a bad idea to start by saying "The consequences have already been pretty disastrous". Rationality 101.
7Ishaan10y
I suppose it could be interpreted that way. It's not like anyone wants research to shut down - everyone agrees that research should continue. There's no political faction that wants to cause trouble. We've talked about much more divisive things in the past. If the question is clueless, I find it rather strange that no one is actually bothering to explain. I've seen much more uninformed questions talked about in the Discussion sections. I guess I seriously underestimated the whole "politics-mindkilling" thing... Fair point.
0ChristianKl10y
Einstein was more productive when it comes to producing scientific breakthrough when he worked in a patent office in 1905 than when he was having big grants. It's not at all clear whether writing grants to run fancy experiments and then publishing papers that don't replicate to have a high enough publication rate to get further grants helps the scientific project.

Bad example. Einstein was A) doing physics at a time when the size of budgets needed to make new discoveries was much smaller B) primarily doing theoretical work or work that relied on other peoples data. Many areas of research (e.g. much of particle physics, a lot of condensed matter, most biology) require funding for the resources to simply to do anything at all.

0ChristianKl10y
I don't think that true. If you take something like the highly useful discovery that taking vitamin D at the morning is more effective than at the evening that discovery was made in the last decade by amateurs without budjets. Fermi estimates aren't easy but that discovery might be worth a year of lifespan. If you look at what the Google people are saying solving cancer is worth three years of lifespan. The people who publish breakthrough results in cancer research have replication rates of under 10 percent. Just as Petrov didn't get a nobel peace price, the people advancing human health don't get biology nobel prices. Relying on other people's data is much easier know that it was in Einsteins time. Open science doesn't go as far as I would like but being able to transfer data easily via computers makes things so much easier. The fact that most work in biology relies on experiments suggests that there are not enough people doing good theoretical work in the field it. I don't know much about particle phyiscs but I'm not sure whether we need as much smart people doing particle physics as we have at the moment.
4JoshuaZ10y
So there are two distinct arguments being made: one is a resource allocation argument (it would be better to spend fewer resources right now on things like particle physics) and the second argument is that in many fields one can still make discoveries with few resources. The first argument may have some validity. The second argument ignores how much work is required in most cases. Yes, one can do things like investigate specific vitamin metabolism issues. But if one is interested in say synthesizing new drugs, or investigating how those drugs would actually impact people that requires large scale experiments. That's not what is going on here. The issue is that biology is complicated. Life doesn't have easy systems that have easy theoretical underpinnings that can be easily computed. There are literally thousands of distinct chemicals in a cell interacting, and when you introduce a new one, even if you've designed it to interact with a specific receptor, it will often impact others. And even if it does only impact the receptor in question, how it does so will matter. You are dealing with systems created by the blind-idiot god.
1ChristianKl10y
You are defending a way of doing biology that plagued by various problems. It's a field where people literally believe that they can perceive more when they blind themselves. There are huge issues in the theoretically underpinning of that approach because the people in the system are too busy writing research that doesn't replicate for top tier journals that requires expensive equipment instead of thinking more about how to approach the field.
3JoshuaZ10y
So every field has problems, but that doesn't mean those problems are "huge". Outside view: An entire field which is generally pretty successful at actually finding what is going on is fundamentally misguided about how they should be approaching the field, or the biologists are doing what they can. Biology is hard. But we are making progress in biology at a rapid rate. For example, the use of genetic markers to figure out how to treat different cancers was first proposed in the early 1990s and is now a highly successful clinical method.
0Douglas_Knight10y
Really? Can you point to a paper demonstrating it's better than classifying cancers the way histologists did in the 80s? Everything I've seen says that it just reconstructs the same classification. But it took ten years for the geneticists to admit that. I've seen more recent genetic classification that might be better than the old ones, but they didn't bother to compare to the old genetic classifications, let alone the histology.
0[anonymous]10y
HER2 receptor. These days those with breast cancer that overexpresses this growth factor receptor tend to get monoclonal antibodies against it, which both suppress its growth effects and tag it for disruption by the immune system. Yes, this is a protein test rather than a genetic test. But it lets the subset of people with this amplification get a treatment that has a large positive absolute effect on those with early-stage cancer.
0JoshuaZ10y
I don't know enough about that subfield to answer that question. If what you are saying is accurate, that's highly disturbing. Most of my exposure to that subfield has been to popular press articles such as this one which paint a picture that sounds much more positive, but may well be highly distorted from what's actually going on.
0ChristianKl10y
You might be but I'm not really. That's a crude method of measuring success. The cost of new drugs rises exponentially via Eroom's law. Big Pharma constantly lays of people. A problem like obesity grows worse over the years instead of progress. Diabetes gets worse. Even if you say that science isn't about solving real world issues but about knowledge, I also think that replication rates of 11% in the case of breakthrough cancer research indicates that the field is not good at finding out what's going on.
2gwern10y
I don't think a flat replication rate of 11% tells us anything without recourse to additional considerations. It's sort of like a Umeshism: if your experiments are not routinely failing, you aren't really experimenting. The best we can say is that 0% and 100% are both suboptimal... For example, if I was told that anti-aging research was having a 11% replication rate for its 'stopping aging' treatments, I would regard this as shockingly too high and a collective crime on par with the Nazis, and if anyone asked me, would tell them that we need to spend far far more on anti-aging research because we clearly are not trying nearly enough crazy ideas. And if someone told me the clinical trials for curing balding were replicating at 89%, I would be a little uneasy and wonder what side-effects we were exposing all these people to. (Heck, you can't even tell much about the quality of the research from just a flat replication rate. If the prior odds are 1 in 10,000, then 11% looks pretty damn good. If the prior odds are 1 in 5, pretty damn bad.) What I would accept as a useful invocation of an 11% rate is, say, an economic analysis of the benefits showing that this represents over-investment (for example, falling pharmacorp share prices) or surprise by planners/scientists/CEOs/bureaucrats where they had held more optimistic assumptions (and so investment is likely being wasted). That sort of thing.
1Lumifer10y
Replication rate of experiments is quite different from the success rate of experiments. An 11% success rate is often shockingly high. An 11% replication rate means the researchers are sloppy, value publishing over confidence in the results, and likely do way too much of throwing spaghetti at the wall...
0gwern10y
Even granting your distinction, the exact same argument still applies: just substitute in an additional rate of, say, 10% chance of going from replication to whatever you choose to define as 'success'. You cannot say that a 11% replication rate and then a 1.1% success rate is optimal - or suboptimal - without doing more intellectual work!
2Lumifer10y
No, I don't think so. An 11% replication rate means that 89% of the published results are junk and external observers have no problems seeing that. Which implies that if those who published it were a bit more honest/critical/responsible, they should have been able to do a better job of controlling for the effects which lead them to think there's statistical significance when in fact there's none. If the prior odds are 1:10,000 you have no business publishing results at 0.05 confidence level.
1gwern10y
Yes, so? As Edison said, I have discovered 999 ways to not build a lightbulb. Huh? No. As I already said, you cannot go from replication rate to judgment of the honesty, competency, or insight of researchers without additional information. Most obviously, it's going to be massively influenced by the prior odds of the hypotheses. No one has any business publishing at an arbitrary confidence level, which should be chosen with respect to some even half-assed decision analysis. 1:10,000 or 1:1000, doesn't matter.
0Lumifer10y
You're still ignoring the difference between a failed experiment and a failed replication. Edison did not publish 999 papers each of them claiming that this is the way to build the lightbulb (at p=0.05). And what exactly prevents the researchers from considering the prior odds when they are trying to figure out whether their results are really statistically significant? I disagree with you -- if a researcher consistently publishes research that cannot be replicated I will call him a bad researcher.
1gwern10y
So? What does this have to do with my point about optimizing return from experimentation? Nothing. But no one does that because to point out that a normal experiment has resulted in a posterior probability of <5% is not helpful since that could be said of all experiments, and to run a single experiment so high-powered that it could single-handedly overcome the prior probability is ludicrously wasteful. You don't run a $50m clinical trial enrolling 50,000 people just because some drug looks interesting. Too bad. You should get over that.
0Lumifer10y
I think our disagreement comes (at least partially) from the different views on what does publishing research mean. I see your position as looking on publishing as something like "We did A, B, and C. We got the results X and Y. Take it for what it is. The end." I'm looking on publishing more like this: "We did multiple experiments which did not give us the magical 0.05 number so we won't tell you about them. But hey, try #39 succeeded and we can publish it: we did A39, B39, and C39 and got the results X39 and Y39. The results are significant so we believe them to be meaningful and reflective of actual reality. Please give our drug to your patients." The realities of scientific publishing are unfortunate (and yes, I know of efforts to ameliorate the problem in medical research). If people published all their research ("We did 50 runs with the following parameters, all failed, sure #39 showed statistical significance but we don't believe it") I would have zero problems with it. But that's not how the world currently works. P.S. By the way, here is some research which failed replication (via this)
1gwern10y
That would be a better world. But in this world, it would still be true that there is no universal, absolute, optimal percentage of experiments failing to replicate, and the optimal percentage is set by decision-theoretic/economic concerns.
0Lumifer10y
Experiments that fail to replicate at percentages greater than those expected from published confidence values (say, posterior probabilities) are evidence that the published confidence values are wrong. A research process that consistently produces wrong confidence values has serious problems.
1gwern10y
How would you know? People do not produce posterior probabilities or credible intervals, they produce confidence intervals and p-values.
1Lumifer10y
I don't see how this point helps you. Either the p-values in the papers are worthless in the sense of not reflecting the probability that the observed effect is real -- in which case the issue in the parent post stands. Or the p-values, while not perfect, do reflect the probability the effect is real -- in which case they are falsified by the replication rates and in which case the issue in the parent post stands.
0gwern9y
p-values do not reflect the probability that the observed effect is real but the inverse, and no one has ever claimed that, so we can safely dismiss this entire line of thought. p-values can, with some assumptions and choices, be used to calculate other things like positive predictive value/PPV, which are more meaningful. However, the issue still stands. Suppose a field's studies have a PPV of 20%. Is this good or bad? I don't know - it depends on the uses you intend to put it to and the loss function on the results. Maybe it would be helpful if I put it in Bayesian terms where the terms are more meaningful & easier to understand. Suppose an experiment turns in a posterior with 80% of the distribution >0. Subsequent experiments or additional data collection will agree with and 'replicate' this result the obvious amount. Now, was this experiment 'underpowered' (it collected too little data and is bad) or 'overpowered' (too much and inefficient/unethical) or just right? Was this field too tolerant of shoddy research practices in producing that result? Well, if the associated loss function has a high penalty on true values being <0 (because the cancer drugs have nasty side-effects and are expensive and only somewhat improve on the other drugs) then it was probably underpowered; if it has a small loss function (because it was a website A/B test and you lose little if it was a worse variant) then it was probably overpowered because you spent more traffic/samples than you had to to choose a variant. The 'replication crises' are a 'crisis' in part because people are basing meaningful decisions on the results to an extent that cannot be justified if one were to explicitly go through a Bayesian & decision theory analysis with informative data. eg pharmacorps probably should not be spending millions of dollars to buy and do preliminary trials on research which is not much distinguishable from noise, as they have learned to their intense frustration & financial cost, to s
0JoshuaZ10y
It isn't a metric of success. It is an example, one of many in the biological sciences. This is likely due largely to policy issues and legal issues more than it is how the biologists are thinking. Clinical trials have gotten large. A systemic problem, but one that has even less to do with biological research than Eroom's law. Obesity is not due to a lack of theoretical underpinnings in biology. The question isn't is the field very good. The question is are the problems which we both agree exist due at all to not enough theory? File drawer effects, cognitive biases, bad experimental design are all issues here, none of which fall into that category.
0ChristianKl10y
Then at what grounds do you claim that the field is succesful? How would you know if it weren't succesful? I'm not saying that theory lacks theoretical underpinnings but that the underpinning is of bad quality. Question about designing experiments in a way that they produce reproduceable results instead of only large p values are theoretical issues. Enough theory sounds like as attempt to quantify the amount of theory. That's not what I advocate. Theories don't get better through increase in their quantity. Good theoretical thinking can simply model and result in less complex theory.
0JoshuaZ10y
That's a good question, but in this context, seeing a variety of novel discoveries in the last few years indicates a somewhat successful field. By the same token, I'm curious what makes you think this isn't a successful field? I've already mentioned the file drawer problem. I'm curious, do you think that is a theoretical problem? If so, this may come down in part due to a very different notion of what theory means. You seem to be treating biology to some extent like it is physics, But these are complex systems. What makes you think that such approaches will be at all successful?
0ChristianKl10y
The fact that Big Pharma has to lay of a lot of scientists is a real world indication that the output of model of finding a drug target, screening thousands of components against it, runs those components through clinical trials to find whether they are any good and then coming out with drugs that cure important illnesses at the other end stops producing results. Eroom's law. Saying that there's a file drawer problem is quite easy. That however not a solution. I think your problem is that you can't imaging a theory that would solve the problem. That's typical. If it would be easy to imagine a theoretical breakthrough beforehand it wouldn't be much of a breakthrough. Look at a theoretical breakthrough of moving from the model of numbers as IV+II=VI to 4+2=6. If you would have talked with a Pythagoras he probably couldn't imaging a theoretical breakthrough like that. I don't. I don't know much about physics. Paleo/Quantified Self people found the thing with Vitamin D in the morning through phenemology. The community is relatively small and the amount of work that's invested into the theoretical underpinning is small. I think in my exposure with the field of biology from various angles that there are a lot of areas where things aren't clear and there room for improvement on the level on epistomolgy and ontology. I just recently preordered two angel sensors from crowdsourcing website indiegogo. I think that the money that the company gets will do much more to advance medicine than the average NHI grant.
1JoshuaZ10y
This seems like extremely weak evidence. Diminishing marginal returns is a common thing in many areas. For example, engineering better trains happened a lot in the second half 19th century and the early 20th century. That slowed down, not because of some lack of theoretical background, but because the technology reached maturity. Now, improvements in train technology do occur, but slowly. On the contrary. We have ways of handling the file drawer problem, and they aren't theory based issues. Pre-registration of studies works. It isn't even clear to me what it would mean to have a theoretical solution of the file drawer problem given that it is a problem about how culture, and a type of problem exists in any field. It makes about as much sense to talk about how having better theory could somehow solve type I errors. The ancient Greeks used the Babylonian number system and the Greek system. They did not use Roman numerals.
-2ChristianKl10y
The file drawer problem is about an effect. If you can estimate exactly how large the effect is when you look at the question of whether to take a certain drug you solve the problem because you can just run the numbers. The concept of the file drawer problem first appeared in 1976 if I can trust google ngrams. How much money do you think it cost to run the experiments to come up with the concept of the file drawer problem and the concept pre-registration of studies? I don't think that's knowledge that got created by running expensive experiments. It came from people engaging in theoretical thinking. Type I errors are a feature of frequentist statistics. If you don't use null hypotheses you don't make type I errors. Bayesians don't make type I errors because they don't have null hypotheses.
4gwern10y
The earliest citation in the Rosenthal paper that coined the term 'file drawer' is to a 1959 paper by one Theodore Sterling; I jailbroke this to "Publication Decisions and Their Possible Effects on Inferences Drawn from tests of Significance - or Vice Versa". After some background about NHST on page 1, Sterling immediately begins tallying tests of significance in a years' worth of 4 psychology journals, on page 2, and discovers that eg of 106 tests, 105 rejected the null hypothesis. On page 3, he discusses how this bias could come about. So at least in this very early discussion of publication bias, it was driven by people engaged in empirical thinking.
-2ChristianKl10y
I think doing a literature review is engaging in using other people data. For the sake of this discussion JoshuaZ claimed that Einstein was doing theoretical work when he worked with other people's data. If I want to draw information from a literature review to gather insights I don't need expensive equipment. JoshuaZ claimed that you need expensive equipement to gather new insights in biology. I claim that's not true. I claim that there enough published information that's not well organised into theories that you can make major advances in biology without needing to buy any equipment. As far as I understand you don't run experiments on participants to see whether Dual 'n' back works. You simply gather Dual 'n' back data from other people and tried doing it yourself to know how it feel like. That's not expensive. You don't need to write large grants to get a lot of money to do that kind of work. You do need some money to pay your bills. Einstein made that money through being a patent clerk. I don't know how you make your money to live. Of course you don't have to tell and I respect if that's private information. For all I know you could be making money by being a patent clerk like Einstein. A scientists who can't work on his grant projects because he of the government shutdown could use his free time to do the kind of work that you are doing. If you don't like the label "theoretic" that's fine. If you want to propose a different label that distinguish your approach from the making fancy expensive experiments approach I'm open to use another label. I think in the last decades we had an explosion in the amount of data in biology. I think that organising that data into theories lags behind. I think it takes less effort to advance biology by organising into theories and to do a bit of phenomenology than to push for further for expensive equipment produced knowledge. If I phrase it that way, would you agree?
2gwern10y
This can be true but also suboptimal. I'm sure that given enough cleverness and effort, we could extract a lot of genetic causes out of existing SNP databases - but why bother when we can wait a decade and sequence everyone for $100 a head? People aren't free, and equipment both complements and substitutes for them. I assume you're referring to my DNB meta-analysis? Yes, it's not gathering primary data - I did think about doing that early on, which is why I carefully compiled all anecdotes mentioning IQ tests in my FAQ, but I realized that between the sheer heterogeneity, lack of a control group, massive selection effects, etc, the data was completely worthless. But I can only gather the studies into a meta-analysis because people are running these studies. And I need a lot of data to draw any kind of conclusion. If n-back studies had stopped in 2010, I'd be out of luck, because with the studies up to 2010, I can exclude zero as the net effect, but I can't make a rigorous statement about the effect of passive vs active control groups. (In fact, it's only with the last 3 or 4 studies that the confidence intervals for the two groups stopped overlapping.) And these studies are expensive. I'm corresponding with one study author to correct the payment covariate, and it seems that on average participants were paid $600 - and there were 40, so they blew $24,000 just on paying the subjects, never mind paying for the MRI machine, the grad students, the professor time, publication, etc. At this point, the total cost of the research must be well into the millions of dollars. It's true that it's a little irritating that no one has published a meta-analysis on DNB and that it's not that difficult for a random person like myself to do it, it requires little in the way of resources - but that doesn't change the fact that I still needed these dozens of professionals to run all these very expensive experiments to provide grist for the mill.

LOL. That's, um, not exactly true. Let's take a new drug trial. You want to find out whether the drug has certain (specific, detectable) effects. Could you please explain how a Bayesian approach to the results of the trial would make it impossible to make a Type I error, that is, a false positive: decide that the drug does have effects while in fact it does not?
-1ChristianKl10y
I don't. A real bayesian doesn't. The bayesian wants to know the probability which with the drug will improve the well being of a patient. The output of a bayesian analysis isn't a truth value but a probability.
4Lumifer10y
So is the output of a frequentist analysis. However real life is full of step functions which translate probabilities into binary decisions. The FDA needs to either approve the drug or not approve the drug. Saying "I will never make a Type I error because I will never make a hard decision" doesn't look good as evidence for the superiority of Bayes...
-2ChristianKl10y
Decisions are not the result of statistical test but of utility functions. A bayesian takes the probability that he gets from his statistics and puts that into his utility function. Type I errors are a feature of statistical tests and not one of decision functions. It's a huge theoretical advance to move from aristotelism to baysianism. Maybe reading http://slatestarcodex.com/2013/08/06/on-first-looking-into-chapmans-pop-bayesianism/ might help you.

There a difference between asking yourself: "Does this drug work better than other drugs?" and then deciding based on the answer to that question whether or not to approve the drug and asking "What's the probability that the drug works?" and making a decision based on it. In practice the FDA does ask their statistical tools "Does this drug work better than other drugs?" and then decides on that basis whether to approve the drug. Why is that a problem? Take an issue like developing new antibiotica. Antibiotica are an area where there a consensus that not enough money goes into developing new ones. The special needs comes out of the fact that bacteria can develop resistance to drugs. A bayesian FDA could just change the utility factor that goes to calculate the value of approving a new antibiotica medicament. Skipping the whole "Does this drug work?"- question and instead of focusing on the question "What's the expected utility from approving the drug?" The bayesian FDA could get a probability value that the drug works from the trial and another number to quantify the seriousness of sideeffects. Those numbers can go together into a utility function for making a decision. Developing a good framework which the FDA could use to make such decisions would be theoretical work. The kind of work in which not enough intellectual effort goes because scientists rather want to play with fancy equipment. If the FDA would publish utility values for the drugs that it approves that would also help insurance companies. A insurance company could sell you an insurance that pays for drugs that exceed a certain utility value for a cerain price. You could simply factor the file drawer effect into such a model. If a company preregisters a trial and doesn't publish it the utility score of the drug goes down. Preregistered trials count more towards the utility of the drug than trials with aren't preregistered so you create an incentive for registration. You can do all sorts of thinks w

Consider Alice and Bob. Alice is a mainstream statistician, aka a frequentist. Bob is a Bayesian. We take our clinical trial results and give them to both Alice and Bob. Alice says: the p-value for the drug effectiveness is X. This means that there is X% probability that the results we see arose entirely by chance while the drug has no effect at all. Bob says: my posterior probability for drug being useless is Y. This means Bob believes that there is (1-Y)% probability that drug is effective and Y% probability that is has no effect. Given that both are competent and Bob doesn't have strong priors X should be about the same as Y. Do note that both Alice and Bob provided a probability as the outcome. Now after that statistical analysis someone, let's call him Trent, needs to make a binary decision. Trent says "I have a threshold of certainty/confidence Z. If the probability of the drug working is greater than Z, I will make a positive decision. If it's lower, I will make a negative decision". Alice comes forward and says: here is my probability of the drug working, it is (1-X). Bob comes forward and says: here is my probability of the drug working, it is (1-Y). So, you're saying that if Trent relies on Alice's number (which was produced in the frequentist way) he is in danger of committing a Type I error. But if Trent relies on Bob's number (which was produced in the Bayesian way) he cannot possibly commit a Type I error. Yes? And then you start to fight the hypothetical and say that Trent really should not make a binary decision. He should just publish the probability and let everyone make their own decisions. Maybe -- that works in some cases and doesn't work in others. But Trent can publish Alice's number, and he can publish Bob's number -- they are pretty much the same and both can be adequate inputs into some utility function. So where exactly is the Bayesian advantage?
0A1987dM10y
Why? X is P(results >= what we saw | effect = 0), whereas Y is P(effect < costs | results = what we saw). I can see no obvious reason those would be similar, not even if we assume costs = 0; p(results = what we saw | effect = 0) = p(effect = 0 | results = what we saw) iff p_{prior}(result = what we saw) = p_{prior}(effect = 0) (where the small p's are probability densities, not probability masses), but that's another story.
0Lumifer10y
You have two samples: one was given the drug, the other was given the placebo. You have some metric for the effect you're looking for, a value of interest. The given-drug sample has a certain distribution of the values of your metric which you model as a random variable. The given-placebo sample also has a distribution of these values (different, of course) which you also model as a random variable. The statistical questions are whether these two random variables are different, in which way, and how confident you are of the answers. For simple questions like that (and absent strong priors) the frequentists and the Bayesians will come to very similar conclusions and very similar probabilities.
0A1987dM10y
Yes, but the p-value and the posterior probability aren't even the same question, are they?
0Lumifer10y
No, they are not. However for many simple cases -- e.g. where we are considering only two possible hypotheses -- they are sufficiently similar.
0ChristianKl10y
No. You don't understand null hypotheis testing. It doesn't measure whether the results arose entirely by chance. It measures whether a specifc null hypothsis can be rejected.
3Lumifer10y
I hate to disappoint you, but I do understand null hypothesis testing. In this particular example the specific null hypothesis is that the drug has no effect and therefore all observable results arose entirely by chance.
0ChristianKl10y
Almost no drug has no effect. Most drug changes the patient and produces either a slight advantage or disadvantage. If what you saying is correct I could simply run n=1 experiments.
2Lumifer10y
You are really determined to fight they hypothetical, aren't you? :-) Let me quote myself with the relevant part emphasized: "You want to find out whether the drug has certain (specific, detectable) effects." And how would they help you? There is the little issue of noise. You cannot detect any effects below the noise floor and for n=1 that floor is going to be pretty high.
1ChristianKl10y
A p-value isn't the probability that a drug has certain (specific, detectable) effects. 1-p isn't either. No, I'm accepting it. The probability of a drug having zero effects is 0. If your statistics give you an answer that a drug has a probability other than 0 for a drug having zero effects your statistics are wrong. I think your answer suggests the idea that an experiment might provide actionable information. But you still claim that every experiment provides an actionable probability when interpreted by a frequentist. If you give a bayesian your priors and then get a posterior probability from the bayesian that probability is in every case actionable.
0Lumifer10y
Again: the probability that a drug has no specific, detectable effects is NOT zero. Huh? What? I don't even... Please quote me. What do you call an "actionable" probability? What would be an example of a "non-actionable" probability?
-1ChristianKl10y
I don't care about detectability when I take a drug. I care about whether it helps me. I want a number that tell me the probability of the drug helping me. I don't want the statisician to answer a different question. Detectability depends on the power of a trial. If a frequentist gives you some number after he analysed an experiment you can't just fit that number in a decision function. You have to think about issues such as whether the experiment had enough power to pick up an effect. If a bayesian gives you a probability you don't have to think about such issues because the bayesian already integrates your prior knowledge. The probability that the bayesian gives you can be directly used.
1Lumifer10y
Drug trials are neither designed to, nor capable of answering questions like this. Whether a drug will help you is a different probability that comes out of a complicated evaluation for which the drug trial results serve as just one of the inputs. I am sorry, you're speaking nonsense.
0ChristianKl10y
That evaluation is in it's nature bayesian. Bayes rule is about adding together different probabilities. At the moment there no systematic way of going about it. That's where theory development is needed. I would that someone like the FDA writes down all their priors and then provides some computer analysis tool that actually calculates that probability. If the priors are correct then a correct bayesian analysis provides me exactly the probability in which I should believe after I read the study.

No, seeing a bunch of novel true discoveries indicates a successful field. However, it's normally hard to independently verify the truth of novel discoveries except in cases where those discoveries have applications.
0JoshuaZ10y
This seems like a nitpick more than a serious remark: obviously one is talking about the true discoveries, and giving major examples of them in biology is not at all difficult. The discovery of RNA interference is in the biochem end of things, while a great number of discoveries have occurred in paleontology as well as using genetics to trace population migrations (both humans and non-humans). So one question here is, for what types of discoveries is your prior high that the discovery is bogus? And how will you tell? General skepticism probably makes sense for a lot of medical "breakthroughs" but there's a lot of biology other than those.

Additional context: only one of those shutdowns has involved a significant fraction of the government suspending its operations for more than 5 days. Before 1980, "shutdowns" followed different rules so that they did not affect government operations nearly as much. Since 1980, every shutdown but one has been 5 days or less. The Clinton-Gingrich shutdown, which began in late 1995, is the only one to last longer (first 5 days, and then 21 more days after a brief truce).

Should effective altruists care about the US gov't shutdown and can we do anything?

No to the second part. Certainly not without abandoning the "effective altruist" label. The US government is something that powerful entities already have huge motivation to influence. Your motivation to change it is laughably trivial. Comparative advantage.

I think that [CDC shutdown] is almost certain to directly cause a nontrivial number of deaths.

Did you, perchance, mean expected deaths? It seems to me that CDC is important iff there is an outbreak of a deadly epidemic. Then one can discuss what the delta-deaths is actually likely to be; but at any rate it does not appear obvious that losing CDC for a month is likely to increase the number of deaths in a non-epidemic (ie, business as usual) environment. So there's a small chance P(epidemic breaks out while shutdown) times a not-very-well-known but conce... (read more)

I was thinking of more mundane things, for example the yearly flu, which kills quite a few people yearly and would kill more but for careful monitoring of strains and preventative vaccination measures. The CDC alone isn't what I'm concerned about. It's the small-to-medium inconvenience distributed over a very large number of research facilities, and the larger inconveniences to projects which are time sensitive.

We should care, the likely damage from this while mainly diffuse impacts will be large. But no, there's not much one can do about this. The effective altruist community is not large enough nor influential enough to have any substantial impact on this matter.

Outspending an organisation like the US chamber of commerce who lobbies a lot won't be cheap. There also the problem of lack of information. The information that you read in newspapers about Washington is not objective but put into circulation to achieve political ends. Understanding the details of the problem enough to be able to usefully engage with the situation would require inside information that most of us probably don't have.
  1. No.
  2. See #1.

You didn't provide any reasons, which is odd. Did you just want me to weigh your opinion by itself?

I see you as someone who generally knows stuff, so your opinion alone does have some weight. However, as it stands, I can't even tell whether the lack of an explanation is meant to imply that this is an obvious conclusion and I'm being silly, or whether you're just making a casual remark. Can you say how confident you are in this opinion?

this is an obvious conclusion and I'm being silly

Yes.

Can you say how confident you are in this opinion?

If I were to attach a probability, it would be far below 1%; even if the most prominent famous person connected to LW I can think of, billionaire Peter Thiel, were to intervene, I still would not expect as high as a 1% chance of meaningful influence on the outcome.

In retrospect it was my mistake, although given my initial state of knowledge I don't think I did anything wrong. 1) I thought there was a possibility that something could be done. As of now, I'll take the majority opinion's word that nothing can be done, even though I'm still not sure why this is true. The opinions from people I trust to assign confidences accurately is sufficient evidence for now. I might investigate myself later if I have time, although the fact that most people think nothing can be done indicates that perhaps it's not worth the time to research it. 2) I didn't mentally classify this under the heading "politics", but under "shit, lots of labs are shutting down for a potentially preventable reason, and many smart people (on this forum, too) think that science research is the single most cost-effective good, so maybe this is a very critical time to act. Maybe if I post, other people who know more than me will think about it from an effective altruism perspective and a useful discussion will spark." It seemed a pretty non-partisan issue, since all sides agree that it's bad. That was actually a mistake - I should have realized that anything tangentially related to politics is a political issue. Despite some of the responses to the contrary, I'm actually still not convinced that this whole shutdown isn't a really, really bad thing...but I guess calculating the harm would be a difficult fermi estimate to pull off.
2Viliam_Bur10y
I'd say the mistake was speaking about disastrous consequences (as a certain fact), when in reality you had little information to back this up. The proper approach in such situation would be asking: "I heard about X. Do you think it will significantly impact Y?" And then the debate would be about the estimated impacts of X (instead of about your overconfidence). The political aspect just makes it worse, but I think speaking about disasters in situations where you have little information would be bad even in non-political areas.

I suspect two reasons: 1) This summarizes a large amount what other people were thinking. Note that the post Gwern is replying to has had a lot of downvotes, so people who think it is obviously not well thought out favor a response like this. 2) Gwern is a highly respected user who almost never says something without fairly good data to back up his positions, so they are operating under this being a summary of Gwern's more detailed position. (A slightly more cynical version of 2 is simply that Gwern has high status here.)

Write a letter to your congresspeople, and do it on paper to maximize the impact. Beyond that, you're looking at going up against big money, and the efficiency is gone.

Can we do anything to remedy the situation?
