I simply use an app called Hosts Editor on my phone to map reddit.com to localhost. This instantly broke a habit I had of wasting time on reddit (an activity I generally regret after the fact, but that I still tended to do whenever I had a few spare minutes) and increased the time I spent on reading more interesting content (instapaper, or books). No downsides I have noticed.

I was surprised at this:

In a recent survey, just 1 percent knew we had cut extreme poverty in half, and 99 percent underestimated the progress. That survey wasn’t just testing knowledge; it was testing optimism—and the world didn’t score so well.

The survey seems to be the one described here: http://www.glocalities.com/news/press-release-global-povert-survey.html

It reveals that 87% of people around the world believe that global poverty has either stayed the same or gotten worse over the past 20 years, when the exact opposite is true – it has more tha

There are a lot of people with incentives to convince you that things are horrible.

Notable categories are people who want to mobilize you to do something, e.g. protest, and people who want your money.

It's a testament to the mainstream media's ability to inform it's audience of import facts about the world. Given the debate we have about alternative facts, the inability of our media matters.

He might have been lucky rather than have a good strategy, yes. Hard to tell.

Oh, I agree. He himself claims that many analysts were saying the same things, and that you would need to be an imbecile to not notice what was going on at the time. My feeling is that he himself does not feel that he made an impressive prediction, and was actually just pointing out that it would inevitably go wrong at some point. in fact he has been talking about the issue for long before 2008, it just happens that the publication of his book came at just the right time to make it look like he predicted it just before it happened. (I may be wrong, and am ... (read more)

I don't have the impression that Taleb goes to any lengths to discourage people from thinking that he made more impressive predictions than he actually did :-).

Taleb's strategy is to absolutely make many bets with high payoff, low downside, expecting most of them to not pay out.

eg. http://www.newsmax.com/finance/StreetTalk/Nassim-Taleb-Shorting-Treasuries/2010/02/04/id/348993/ he was wrong, but as he puts it:

“You have a very small probability of making money,” he said. “But if you’re right, you’ll never see a public plane again.”

another quote:

"I did 700,000 trades in career, was "wrong" on between 650,000 and 695,000."

We can assume that he is either lucky, or well calibrated, since he ... (read more)

Citation needed. I believe he tried to run a hedge fund for a while, basically buying volatility. He failed and, as far as I know, closed the fund down.

Source for the 2008 crisis prediction would be his book The Black Swam (I remember checking the publication date when reading The Black Swan, since it did seem very prescient):

Globalization creates interlocking fragility, while reducing volatility and giving the appearance of stability. In other words it creates devastating Black Swans. We have never lived before under the threat of a global collapse. Financial Institutions have been merging into a smaller number of very large banks. Almost all banks are interrelated. So the financial ecology is swelling

The saying goes that economists have successfully predicted nine of the last five recessions. In that passage, Taleb correctly identifies some systemic problems that led to the 2008 crash. That's not quite the same thing as predicting the crash. (If I say "San Francisco is built on a big fault, and it hasn't had a really big earthquake for some time." do I get to claim I predicted the Next Big One, if and when it happens?) So (1) the impressiveness of that passage depends on how unusual it was to recognize those problems. I don't know the answer to that; perhaps scarcely anyone else did, or perhaps most of the people with any information did but most of them found it expedient not to say so, or perhaps actually lots of people said so and we didn't listen. And (2) whether or not we take this as a prediction, and taking him at his word that he predicted Brexit and Trump and whatever else he said he predicted: what else has he predicted, and how did the other predictions turn out? For instance: perhaps all his recent predictions have been of the form "populism is in the ascendant". If so, then that would lead to correct Brexit and Trump predictions, and maybe some others, since populism is indeed doing well. If he noticed that before everyone else, that's impressive. But it doesn't necessarily indicate that he'll predict well outside that domain. Or perhaps he's predicted hundreds of things and most of them were wrong -- but he doesn't mention those. If so, saying "I predicted Brexit and Trump" would be entirely misleading and he deserves no credit for anything. Or perhaps he's predicted hundreds of surprising things and got lots of them right, in which case we should indeed take seriously the idea that there's some fundamental thing he's doing right and others are doing wrong. Anyone got more information about his actual predictions and how they've turned out?

I don't think that the dev's touched predictionbook in quite a while. In general discovery of interesting public predictions doesn't work well because it's not easy to search and there are no tags.

Yes, this is true. I believe they accept pull requests but there has not been much development for a long time and the site is quite basic.

I didn't know about this one, thank you!

0ChristianKl
That's might be true, but from my perspective, a few pull requests won't change the fate of predictionbook significantly. It's likely that another service will sooner or later overtake it. I like the Android App at it's current state but don't know how much time it's creator plans to invest in it in total. For personal prediction tracking the Android App is already more handy for me than predictionbook as I caryy my mobile phone around and it's relatively straightforward to add new predictions when I have nothing else to do at the moment while traveling from place A to B. Arbital might sooner or later build it's own prediction tracking. It's also possible that someone starts a completely new project.

(some previous discussion of predictionbook.com here)

[disclaimer: I have only been using the site seriously for around 5 months]

I was looking at the growth of predictionbook.com recently, and there has been a pretty stable addition of about 5 new public predictions per day since 2012 (that is counting only new predictions, not including additional wagers on existing predictions). I was curious why the site did not seem to be growing, and how little it is mentioned or linked to on lesswrong and related blogs.

Just adding to the other responses: I also use Metaculus and like it a lot. In another thread, I posted a rough note about its community's calibration. Compared to PredictionBook, the major limitation of Metaculus is that users cannot create and predict on arbitrary questions, because questions are curated. This is an inherent limitation/feature for a website like Metaculus because they want the community to focus on a set of questions of general interest. In Metaculus's case, 'general interest' translates mostly to 'science and technology'; for questions on politics, I suggest taking a look at GJ Open instead.

I use Metaculus a lot, and have made predictions on the /r/SpaceX subreddit which I need to go back and make a calibration graph for. (They regularly bet donations of reddit gold, and have occasional prediction threads, like just before large SpaceX announcements. They would make an excellent target audience for better prediction tools.) I've toyed with the idea of making a bot which searched for keywords on Reddit/LW, and tracked people's predictions for them. However, since LW is moving away from the reddit code base, I'm not sure if building such a bot would make sense right now.

I don't think that the dev's touched predictionbook in quite a while. In general discovery of interesting public predictions doesn't work well because it's not easy to search and there are no tags. There's https://www.metaculus.com and https://www.gjopen.com/ for curated public predictions. For private prediction there's a new Android App (still very much in Beta and in development): https://play.google.com/store/apps/details?id=squirrelinhell.lwpredictions I also did a bunch of prediction tracking in less structured ways. Our LW dojo had a while a shared Workflowy for predictions.

Coming up with criteria and metrics on the economy is pretty easy

I think it can be quite hard to do this in the context of evaluating a presidency. For example while you could look at GDP, unemployment, etc. it can be hard to determine if the president had much impact on those numbers.

Does anyone know if there have been efforts to quantify the impact of a president on the economy? I would imagine that most of the change is due to randomness/external factors.

Education

This is another tricky one, in that we might need to wait more than 4 years to see the results for a lot of metrics.

0NatashaRostova
I agree. In fact, I think coming up with criteria and metrics on the economy is profoundly challenging within the US context. We know there are right tail events (inflation, unemployment, etc) that are very strong. But when they are all generally stable, or within the realm of stability, but the variation within demographics and geographies of the US is huge, the value of the metrics can start to dramatically collapse IMO.
