Why is EA so enthusiastic about forecasting?

My sense is that EA overrates forecasting a bit and that the world underates it a lot. 

Some underrated views I suggest:

• As Michael Story points out (emphasis his): "Most of the useful information you produce [in forecasting] is about the people, not the world outside. Forecasting tournaments and markets are very good at telling you all kinds of things about your participants: are they well calibrated, do they understand the world, do they understand things better working alone or in a team, do they update their beliefs in a sensible measured way or swing about all over the place? If you want to get a rough epistemic ranking out of a group of people then a forecasting tournament or market is ideal. A project like GJP (which I am very proud of) was, contrary to what people often say, not an exercise primarily focused on producing data about the future. It was a study of people! The key discovery of the project wasn’t some vision of the future that nobody else saw, it was discovering the existence of consistently accurate forecasters (“superforecasters”) and techniques to help improve accuracy. The book Superforecasting was all about the forecasters themselves, not the future we spent years of effort predicting as part of the study, which I haven’t heard anyone reference other than as anecdotes about the forecasters."
  • I don't really feel I can add to this quote. Forecasting is useful for filtering people but less useful for finding truth. It's easy to overrate
• It is difficult to forecast things policy makers actually care about. Forecasting sites forecast things like "will Putin leave power" rather than "If Putin leaves power between July 18th and the end of Aug how will that affect the likelihood of a rogue nuclear warhead". And I'm confident that question isn't actually specific enough in some way I don't understand. And even if it were,  decision makers would have to trust the results, which they currently largely don't.
• Forecasting beyond 3 years is not good. Anything above .25 is worse than random. Many questions are too specific and too far away for forecasting to be useful to them.

Forecasting is more useful as a filtering tool/a personal improvement tool than as part of better decision making. I suggest that individuals would gain from playing the estimation game each month and taking the hits that reality deals, but there are many things we could do to improve ourselves and if this doesn't fit for you, fair enough.

But the idea that every org should be forecasting or that every process should involve forecasting doesn't seem to fit in reality. I still look for ways it can (maybe there is a silver bullet!)  but I don't think you, the median EA should. If you want to test your knowledge of a topic, forecast on it. If you see someone has a good track record, consider taking their thoughts more seriously. Other than that, probably don't think that much more than you are interested to/you think it's important to already.

I both think that some groups in EA are slightly overenthusiastic about forecasting^[1] (while other subgroups in EA don't forecast enough), and that forecasting is underused/undervalued in a lot of the world for a number of different reasons. And I'd also suggest looking at this question less from the lens of "why is EA more into forecasting than other groups?" and more from the lens of "some groups are into forecasting while others aren't, why is that?"

More specific (but still quick!)  notes:

1. I'd guess reasons for why other groups are less enthusiastic about forecasting can vary significantly.
   1. E.g.: 
      1. People in governments and the media (and maybe e.g. academia) might view forecasting as not legible enough, or credentialist enough, and the relevant institutions might be slower to change. I don't know how much different factors contribute in different cases. There might also be legal issues for some of those groups. 
      2. I think some people have argued that in corporate settings, people in power are not interested in setting up forecasting-like mechanisms because it might go against their interests. Alternatively, I've heard arguments that middle management systems are messed up, meaning that people who are able to set up forecasting systems in large organizations are promoted and the projects die. I don't know how true these things are.
2. I think people who end up in EA are often the kinds of people who'd also be more likely to find forecasting interesting — both for reasons that are somewhat baked into common ~principles in EA, and for other reasons that look more like biases/selection effects.
3. I'm not sure if you're implying that EA is one of the most extremely-into-forecasting groups, but I'm not sure that this is true. Relatedly, if you're looking to see whether/where forecasting is especially useful, looking at the different use cases as a whole (rather than zooming into EA-vs-not-EA as a key division) might be more useful. 
   1. E.g. sports (betting), trading, and maybe even the weather might be areas/fields/subcultures that rely a lot on forecasting. Wikipedia lists lots of "applications" in its entry on forecasting, and they include business, politics, energy, etc. 
   2. [Edit: this is not as informative as I thought! See Austin's comment below.] Manifold has groups, and while there's an EA group, it's only 2.2K people, while groups like sports (14.4k people) and politics (16.4k people) are bigger. This is more surprising to me since Manifold is particularly EA-aligned.^[2] 
   3. The forecasting group on Reddit looks dead, but it looks like people in various subreddits are discussing forecasts on machine learning, data science, business, supply chains, politics, etc. (I also think that forecasting might be popular in crypto-enthusiast circles, but I'm not sure.)
4. This is potentially minor, but given that a lot of prediction-market-like setups with real money are illegal, as far as I understand, the only people who forecast on public platforms are probably those who are motivated by things like reputation, public good benefits, or maybe charity in the case of e.g. Manifold. So you might ask why Wikipedia editors don't forecast as much as EAs.

   You could claim that this is a sign that EA is more into forecasting, but I'm not sure; EA is also more into creating public-good technology, so even if lots of e.g. trading firms were really excited about forecasting, I'd be unsurprised if there weren't many ~public forecasting platforms that were supported by those groups. (And there are in fact a number of forecasting platforms/aggregators whose relationship to EA is at least looser, unless I'm mistaken, like PredictIt, PolyMarket, Betfair, Kalshi, etc.)

Some thoughts:

I think that you can think about "forecasting" as one of a collection of intellectual practices that the EA community is unusually focused on. 

Other practices/norms include:
- "Scout Mindset"
- Bayesian Thinking
- Lots of care/interest about analytical philosophy
- A preferences for empirical data/arguments
- A mild dislike for many kinds of emotions arguments
- Rationalism / Rationalist Fiction

I think that a background variable here is that EA is close to an intellectual community of thinkers that use similar tools and practices. Thinkers like Steven Pinker, Matthew Yglesias, Robin Hanson, Bryan Caplan, and Andrew Gelman come to mind as people with somewhat similar styles and interests. Many of these people also showed unusual interest in "forecasting". 

So some questions here would be:
1. How well does EA fit into some outer intellectual tribes, like I hinted at above?
2. What preferences/norms do these tribes have, and how justified are they?
3. Why aren't all of these preferences/norms more common? 

I think that "forecasting" as we discuss it is often a set of norms like:
1. Making sure that forecasts are recorded and scored.
2. Making sure forecasters are incentivized to do well.
3. Making sure that the top forecasters are chosen for future rounds.

To do this formally requires a fair bit of overhead, so it doesn't make much sense for small organizations. 

I think that larger organizations either know enough to vet and incentivize their existing analysts (getting many of the benefits of forecasters), or don't, in which case they won't be convinced to use forecasters.  (I think that obvious explanations are some of the reason, but  I do have questions here) 

Society-wide, I think most people don't care about forecasters for similar reasons that most people don't care about Bayesian Thinking, Scott Alexander, or Andrew Gelman. I think these tools/people are clever, but others aren't convinced/knowledgeable of them. 

My understanding is that the empirical basis for the forecasting comes from the academic research of Phillip Tetlock, summarised in the book Superforecasting (I read the book recently, it's pretty good). 

Essentially, the research signed up people to conduct large amounts of forecasts about world events, and scored them on their accuracy. The research found that certain people were able to consistently outperform even top intelligence experts. These people used the sort of techniques familiar to EA: analysing problems dispassionately, breaking them down into pieces, putting percentage estimates on them, and doing frequent pseudo-bayesian "updates". I say pseudo-bayesian because a lot of them weren't actually using bayes theorem, instead just bumping the percentage points up and down, helped with the intuition they developed, which apparently still worked. 

One theory as to why this type of forecasting works so well is that it makes a forecasting a skill with useful feedback: If a prediction fails, you can look at why, and adjust your biases and assumptions accordingly.

Two important caveats that are often overlooked with this research: First, all these predictions were of bounded probability, where the question-makers estimated probability was in the range between 5% and 95%. So no million to one shots, because you'd have to make a million of them to check if the predictions were correct. Second, they were all of short term predictions. Tetlock states multiple times in his book that he thinks forecasts beyond a few years will be fairly useless. 

So, if the research holds up, the methods used by EA are the gold standard in short-term, bounded probability forecasting. It makes sense to use it for that purpose. But I don't think this means that expertise in these problems will transfer to unbounded, long term forecasts like "will AGI kill us all in 80 years". It's still useful to estimate those probabilities to more easily discuss the problem, but there is no reason to expect these estimates to have much actual predictive power. 

why is Tetlock-style judgmental forecasting so popular within EA, but not that popular outside of it?

The replies so far seem to suggest that groups outside of EA (journalists, governments, etc) are doing a smaller quantity of forecasting (broadly defined) than EAs tend to.

This is likely correct but it is also the case that groups outside of EA (journalists, governments, etc) are doing different types of forecasting than EAs tend to. There is less "Tetlock-style judgmental" forecasting and more use of other tools such as horizon scanning, scenario planning, trend mapping, etc, etc.

(E.g. see the UK government Futures Toolkit, although note the UK government also has a more Tetlock-style Cosmic Bazaar) 

So it also seems relevant to ask: why does EA focuses very heavily on "Tetlock-style judgmental forecasting", rather than other forecasting techniques, relative to other groups?

I would be curious to hear people's answers to this half of the question too. Will put my best guess below.

– – 

My sense is that (relative to other futures tools) EA overrates "Tetlock-style judgmental" forecasting a lot and that the world underrates it a bit. 

I think "Tetlock-style" forecasting is the most evidence based, easy to test and measure the value of, futures technique. This appeals to EAs who want everything to be measurable. Although it leads to it being somewhat undervalued by non-EAs who undervalue measurability.

I think the other techniques have been slowly developed over decades to be useful to decision makers. This appeals to decision makers who value being able to make good decisions and having useful tools. Although it leads to them being significantly undervalued by EA folk who tend to have less experience and a "reinvent the wheel" approach to good decision making to the extent that they often don’t even notice that other styles of forecasting and futures work even exist!

One theory is that EA places unusual weight on issues in the long-term future, compared to existing actors (companies, governments) who are more focused on eg quarterly profits or election cycles. If you care more about the future, you should be differentially excited about techniques to see what the future will hold.

(A less-flattering theory is that forecasting just seems like a cool mechanism, and people who like EA also like cool mechanisms.)
