Grading 2019 Predictions

I make predictions every year to put empirical tests on my model of the world. I tend to do a lot of predictions, in order to get a larger dataset, and at the end of the year, I grade them. These were made last year in March.  I’ve placed levels of confidence for each prediction with the odds I would bet on those outcomes in the vein of Bryan Caplan. I’ve created a chart at the end to show my calibration versus perfect calibration.

  1. Trump Approval Rating end of year <50% (Gallup): 95% ✔️
  2. Trump Approval Rating end of year <45% (Gallup): 90% (was 45% exactly)
  3. Trump Approval Rating end of year < 40% (Gallup): 70%
  4. US will not get involved in any new major war with death toll of > 100 US soldiers: 60% ✔️
  5. No single terrorist attack in the USA will kill > 100 people: 95% ✔️
  6. The UK will not leave the EU this year: 80% ✔️
  7. North Korea will still be controlled by the Kim dynasty: 95% ✔️
  8. North Korea will not conduct a nuclear test this year: 60% ✔️
  9. North Korea will not conduct a missile test this year: 60% They conducted 10, with several launching many missiles
  10. North Korea will not agree to give up nuclear weapons entirely, contingent on US troops staying in the Korean peninsula: 99% ✔️
  11. North Korea will not agree to give up nuclear weapons as a result of any negotiations: 90% ✔️
  12. Yemeni civil war will still be happening: 70% ✔️
  13. S&P 500 2019 >10% growth (from 2506 on Jan 1): 60% ✔️
  14. S&P 500 will be between 2400 and 3100: 80% (80% confidence interval) was 3231
  15. Unemployment rate December 2019 < 6%: 80% ✔️
  16. Unemployment rate December 2019 < 5%: 70% ✔️
  17. WTI Crude Oil price up by 10% (from $45.41): 70% ✔️
  18. Price of Bitcoin in dollars up over the year (Coinbase – 3823 Jan 1): 70% ✔️ was $7163
  19. Price of Bitcoin < $8,000 (does not double): 60% ✔️
  20. Price of Bitcoin > $1900 (does not lose half value): 70% ✔️
  21. Price of Bitcoin < $12,000 (does not triple): 70% ✔️
  22. Drivechain opcodes not soft-forked into Bitcoin: 80% ✔️
  23. No drivechains soft-forked into existence: 99% ✔️
  24. US government does not make Bitcoin ownership or exchange illegal: 95% ✔️
  25. Self-driving cars will not be available this year for general purchase: 95% ✔️
  26. Self-driving cars will not be available this year to purchase / legally operate for < $100k: 99% ✔️
  27. I will not be able to buy trips on self-driving cars from Uber/Lyft/Waymo in a location I am living: 95% ✔️
  28. I will not be able to order groceries on self-driving cars in a location I am living: 90% ✔️
  29. I will not be able to buy a trip on a self-driving car from Uber/Lyft/Waymo without a backup employee in the car anywhere in the US: 80% ✔️ This is tough. You can get self driving cars in Phoenix, but only if you’re part of the Waymo beta and so far they are free, so no “buying”.
  30. The artificial general intelligence alignment problem will not be seen as the most important problem facing humanity: 99% ✔️
  31. Humans will not be in lunar orbit in 2019: 99% ✔️
  32. SpaceX Falcon Heavy rocket will launch again this year: 90% ✔️
  33. SpaceX will bring humans to low earth orbit: 60%
  34. SpaceX will test the “Starship” mock up this year: 70% ✔️ (pretty sure I just meant this giant water tower thing, not a real launch)
  35. Mexican government does not pay for wall: 99% ✔️ (lol)
  36. Border wall construction not complete by end of 2019: 99% ✔️ (some construction occurred, mostly replacing existing wall)
  37. National Debt increases by >$1 trillion (from
    $21,943,897,000,000): 90% ✔️ (was $23.201 trillion on Jan 1 2020)
  38. There will not be a significant decrease in trade barriers between US and China from pre-2017 tariff levels: 90% ✔️
  39. Democratic RCP front runner will not be Bernie Sanders: 80% ✔️ (front runner on Jan 1 was Biden)
  40. Democratic RCP front runner will not be Kamala Harris: 80% ✔️
  41. Democratic RCP front runner will not be Beto O’Rourke: 80% ✔️
  42. Trump not removed from office or resign: 95% ✔️
  43. Trump not impeached: 70% I was not expecting this
  44. No CRISPR edited babies will be born: 80% (it turns out the researcher responsible for the two 2018 CRISPR edited babies had already treated a third unborn child in 2018 when the story broke. Apparently the third baby was born in 2019 if you carefully read Xinhua, so technically this prediction is wrong, although I meant no other researcher would do anything. Remember to properly word your predictions!)
  45. No full year US government budget will be passed (only several months spending): 90% ✔️ (they basically only do continuing resolutions now)
  46. Some tariffs raised: 90% ✔️ (like a bunch)
  47. Trump administration does not file a lawsuit against any news organization for defamation: 90% ✔️
  • I got 4 of 6 predictions correct at 60% confidence
  • I got 7 of 9 predictions correct at 70% confidence
  • I got 7 of 9 predictions correct at 80% confidence
  • I got 8 of 9 predictions correct at 90% confidence
  • I got 7 of 7 predictions correct at 95% confidence
  • I got 6 of 6 predictions correct at 99% confidence

Overall, not bad at all, and we should note that from last year’s grading, my 60% confidence predictions have tended to be overconfident. I only had 6 of those predictions this year, so actually 66% is the closest I could have been to perfect calibration. 70% also ended up being a bit overconfident, but a single additional missed prediction here would have dropped me down to 66% as well. Had I moved one of my correct 70% predictions to 80%, I would have been perfectly calibrated.

Combining this data and data from last year gives:

  • I got 11 of 15 predictions correct (73%) at 60% confidence
  • I got 14 of 20 predictions correct (70%) at 70% confidence
  • I got 14 of 17 predictions correct (82%) at 80% confidence
  • I got 14 of 15 predictions correct (93%) at 90% confidence
  • I got 16 of 17 predictions correct (94%) at 95% confidence
  • I got 10 of 10 predictions correct (100%) at 99% confidence

In 2018, as I noted in the post last year, I should have made some of my 60% predictions at a higher confidence, but other than that, these predictions are remarkably well calibrated if I do say so myself.

I hope to post my 2020 predictions soon.

2019 Predictions

I’ve made predictions for the past several years, and here are my predictions for 2019, a bit late. I’ve noticed that when discussing politics or difficult subjects with other people with whom I have strong differences, a possible avenue of understanding is to make a prediction about the world with odds. Most people don’t accept these bets or predictions, which I think are one of the best ways to test different models of the world against each other. Nonetheless, I think it’s personally beneficial to list predictions and accompanying odds each year to see test my model of the world.

  1. Trump Approval Rating end of year <50% (Gallup): 95%

  28. I will not be able to order groceries on self-driving cars in a location I am living: 90%
  29. I will not be able to buy a trip on a self-driving car from Uber/Lyft/Waymo without a backup employee in the car anywhere in the US: 80%
  30. The artificial general intelligence alignment problem will not be seen as the most important problem facing humanity: 99%
  31. Humans will not be in lunar orbit in 2018: 99%
  32. SpaceX Falcon Heavy rocket will launch again this year: 90%
  33. SpaceX will bring humans to low earth orbit: 60%

  45. No full year US government budget will be passed (only several months spending): 90%
  46. Some tariffs raised: 90%
  47. Trump administration does not file a lawsuit against any news organization for defamation: 90%

I’d like to comment on every prediction, but I’m afraid it would take too much time. The predictions I find most interesting are whether the UK will leave the EU. I’m going by what predictions markets say, but I’m not really sure it will play out with only a few weeks to go and no deal. I’m also quite interested in the Democratic Presidential primary race, but I’m afraid the nomination will be trending towards someone pretty left wing. I’m also interested in whether Trump will be removed from office. I put the chances of Trump being impeached at 30% to stay in line with prediction markets, but my gut is that I should put that chance even lower.

2018 Predictions

Untestable knowledgeable cannot be scientific.  To avoid the problems of retroactively placing events into your narrative of the world, predictions must be laid out before events happen. If you try to use your model of the world to create testable predictions, those predictions can be proven right or wrong, and you can actually learn something. Incorrect predictions can help update our models.

This is, of course, the basis for the scientific method, and generally increasing our understanding of the world. Making predictions is also important for making us more humble; we don’t know everything and so putting our beliefs to the test requires us to reduce our certainty until we’ve researched a subject before making baseless claims.  Confidence levels are an important part of predictions, as they force us to think in the context of value and betting: a 90% confidence level means I would take a $100 bet that required me to put up anything less that $90. Moreover, it’s not just a good idea to make predictions to help increase your knowledge; people who have opinions but refuse to predict things with accompanying confidence levels, and therefore refuse to subject their theories to scrutiny and testability, must be classified as more fraudulent and intellectually dishonest.

Before I take a look at how I did this past year, and see if my calibration levels were correct, I should look at some hard fork predictions I made in July:

  1. There will be a Bitcoin Cash block mined before 12 AM August 2, US Eastern time: 80%
  2. The price of Bitcoin Cash at 12 AM August 2, US Eastern time will be <10% of Bitcoin’s price: 70%
  3. The price of Bitcoin Cash on August 5 will be < 10% of Bitcoin’s price: 90%
  4. The price of Bitcoin Cash on September 1 will be < 10% of Bitcoin’s price: 90%
  5. The value of all transactions of Bitcoin Cash around September 1 (maybe averaged over a week?) will be < 10% of the value of all transactions in Bitcoin: 95%

I did not predict that Bitcoin Cash would have long term staying power. In retrospect, I should have had more confidence that it would be similar to Ethereum Classic, which has remained for over a year now.

Now for predictions made at the beginning of the year:

  32. Some increased spending on immigration through expanding CBP, ICE, or the border fence: 80%
  33. Corporate Tax Rate will be cut to 20% or below: 50% (it was 21%)
  34. Obamacare (at least mandate, community pricing, pre-existing conditions) not reversed: 80%
  35. Budget deficit will increase: 90% (Not if you go by National Debt increase January to January)

  38. The US will not significantly change its relationship to NAFTA: 60%
  39. Federal government institutes some interference with state level legal marijuana: 60%

  41. Trump administration does not file a lawsuit against any news organization for defamation: 60%
  42. Trump not impeached (also no Trump resignation): 95%

Postlibertarian

  1. Postlibertarian.com to have >15 more blog posts by July 1, 2017: 80%
  2. Postlibertarian.com to have >30 blog posts by end of year: 70%
  3. Postlibertarian.com to have fewer hits than last year (no election): 60%
  4. Postlibertarian Twitter account to have <300 followers: 90%
  5. Postlibertarian Twitter account to have >270 followers: 60%
  6. Postlibertarian Subreddit to have <100 subscribers: 90%

I missed all the ones I marked as 50% confident, but I’ve realized this category conveys no mathematical information. I could have also listed the predictions as simultaneously saying that there was a 50% chance the exact opposite of the statement occurred, so actually, I got exactly half of them right, and I will always get exactly half of them right. This makes the category completely useless, and so I have decided to avoid posting any predictions of exactly 50% accuracy for next year.

In the other categories:

  • Of items I marked as 60% confident, 10 were correct out of 13.
  • Of items I marked as 70% confident, 5 were correct out of 7.
  • Of items I marked as 80% confident, 9 were correct out of 12.
  • Of items I marked as 90% confident, 7 were correct out of 9.
  • Of items I marked as 95% confident, 2 were correct out of 3.
  • Of items I marked as 99% confident, 4 were correct out of 4.

This may not look great, but is better than last year. Additionally, the big problem is the 95% predictions, which was severely hurt by my poor decision to make predictions about the Bitcoin hard fork, an event which hadn’t really happened before. Ignoring those predictions made in July would change my scores to:

  • Of items I marked as 60% confident, 10 were correct out of 13.
  • Of items I marked as 70% confident, 4 were correct out of 6.
  • Of items I marked as 80% confident, 8 were correct out of 11.
  • Of items I marked as 90% confident, 6 were correct out of 7.
  • Of items I marked as 95% confident, 2 were correct out of 2.
  • Of items I marked as 99% confident, 4 were correct out of 4.

That’s actually remarkably well, with perhaps some 60% predictions that needed more confidence. Moreover, it’s clear I had no business making predictions about Bitcoin with such high confidence, nor did anyone this year. I will definitely be dialing back my confidence levels in Bitcoin price predictions next year, and I’ve focused a bit more of whether Drivechain will be adopted.

*I modified prediction #31 on January 24th from 70% positive to 60% negative. This feels early enough that I can still call it a prediction, and I’m not sure why I was so confident in December when I wrote these.

Bitcoin Hard Fork Predictions

Tomorrow there is scheduled to be a hard fork of the Bitcoin blockchain and network. There’s a fair amount of uncertainty over what will happen. The hashrate is unknowable until the fork occurs. The price seems to be around 10% of the price of Bitcoin. However, there aren’t too many exchanges that will be accepting this currency, and there are even fewer places you can actually spend it.

I’m going to make some predictions about it to put on record what I think is going to occur and to see how correct or incorrect I end up being.

  1. There will be a Bitcoin Cash block mined before 12 AM August 2, US Eastern time: 80%
  2. The price of Bitcoin Cash at 12 AM August 2, US Eastern time will be <10% of Bitcoin’s price: 70%
  3. The price of Bitcoin Cash on August 5 will be < 10% of Bitcoin’s price: 90%
  4. The price of Bitcoin Cash on September 1 will be < 10% of Bitcoin’s price: 90%
  5. The value of all transactions of Bitcoin Cash around September 1 (maybe averaged over a week?) will be < 10% of the value of all transactions in Bitcoin: 95%

I have mixed hopes for the success of Bitcoin Cash. On the one hand, I wrote previously that if the two factions in Bitcoin split, we could have a competitive market showing which rules were better. However, due to network effects, I still don’t think it could happen and be very successful. Supposing it did succeed though (had a pretty high market price), what would that mean? I suppose it would mean forks would become more common. That might be better for competition, but not for stability of the currency.

Ultimately, the idea that it would be fairly easy to make a successful hard fork of Bitcoin would be pretty devastating to Bitcoin’s health. It would mean consensus doesn’t mean much, it would mean the Bitcoin community could splinter pretty easily, which would therefore mean Bitcoin’s usefulness as a currency decreases as each part of the community would be using their own forked blockchain and coin. Something like sidechains seems like a much better implementation of this idea.

I should probably also disclose that I do not have much faith in the current governance model of Bitcoin Cash, and that does concern me a bit as well. I hope that hasn’t clouded my judgment of the actual technological and economic implications, but only time will tell if my predictions are true.

2017 Predictions

It’s fun to have opinions, and it’s easy to craft a narrative to fit your beliefs. But it’s especially dangerous to look back at events and place them retroactively into your model of the world. You can’t learn anything if you’re only ever looking for evidence that supports you.  However, if you try to use your model of the world to create testable predictions, those predictions can be proven right or wrong, and you can actually learn something. Incorrect predictions can help update our models.

This is, of course, the basis for the scientific method, and generally increasing our understanding of the world. Making predictions is also important for making us more humble; we don’t know everything and so putting our beliefs to the test requires us to reduce our certainty until we’ve researched a subject before making baseless claims.  Confidence levels are an important part of predictions, as they force us to think in the context of value and betting: a 90% confidence level means I would take a $100 bet that required me to put up anything less that $90. Moreover, it’s not just a good idea to make predictions to help increase your knowledge; people who have opinions but refuse to predict things with accompanying confidence levels, and therefore refuse to subject their theories to scrutiny and testability, must be classified as more fraudulent and intellectually dishonest.

First let’s take a look at how I did this past year, and see if my calibration levels were correct. Incorrect predictions are crossed out.

Postlibertarian Specific

  2. Postlibertarian Twitter to have more than 240 followers:  70%
  3. Postlibertarian.com to have >10k page loads in 2016: 50% (had 30k according to StatCounter)
  4. The predictions on this page will end up being underconfident: 60%

World Events

  1. Liberland will be recognized by <5 UN members: 99% (recognized by 0)
  2. Free State Project to reach goal of 20,000 people in 2016: 50% (occurred February 3rd)
  3. ISIS to still exist: 80%
  4. ISIS to kill < 100 Americans 2016: 80% (I think <100 were killed by any terrorists, fewer in combat)
  5. US will not get involved in any new major war with death toll of > 100 US soldiers: 80%
  6. No terrorist attack in the USA will kill > 100 people: 80% (50 did die in the Orlando shooting unfortunately)
  7. Donald Trump will not be Republican Nominee: 80% (whoops)
  8. Hillary Clinton to be Democratic nominee: 90%
  9. Republicans to hold Senate: 60%
  10. Republicans to hold House: 80%
  11. Republicans to win Presidential Election: 50% (I predicted in December, Nate Silver had Trump at 35% the day of, who’s a genius now??)
  12. I will vote for the Libertarian Presidential Candidate: 70% *
  13. S&P 500 level end of year < 2500: 70%
  14. Unemployment rate December 2016 < 6% : 70%
  15. WTI Crude Oil price < $50 : 80%
  16. Price of Bitcoin > $500:  60%
  17. Price of Bitcoin < $1000: 80%
  18. Sentient General AI will not be created this year: 99%
  19. Self-driving cars will not be available this year to purchase / legally operate for < $100k: 99%
  20. I will not be able to rent trips on self-driving cars from Uber/ Lyft: 90% **
  21. Humans will not land on moon by end of 2016: 95%
  22. Edward Snowden will not be pardoned by end of Obama Administration: 80% ***

*I didn’t personally vote for the libertarian candidate, but I did trade my vote, resulting in Gary Johnson getting two votes more than he would have had I not voted at all. I’m counting this as at least a vote for Johnson.

**Technically, I am not particularly able to get a ride on a self-driving Uber because I don’t live in Pittsburgh, but I don’t think that’s what I meant. I also didn’t expect any self-driving Uber rides to be available anywhere, so I’m counting it against me.

***Obama still has a few weeks to pardon Snowden, but it’s not looking good

So let’s take a look at how I did by category:

  • Of items I marked as 50% confident, 3 were right and 0 were wrong.
  • Of items I marked as 60% confident, 3 were right and 0 were wrong.
  • Of items I marked as 70% confident, 4 were right and 1 was wrong.
  • Of items I marked as 80% confident, 7 were right and 2 were wrong.
  • Of items I marked as 90% confident, 1 was right and 1 was wrong.
  • Of items I marked as 95% confident, 1 was right and 0 were wrong.
  • Of items I marked as 99% confident, 3 were right and 0 were wrong.

As you can see from this data graphed, I have absolutely no idea what I’m talking about when it comes to predictions.

You’re supposed to be as close to the perfect calibration line as possible. The big problems are that I only had 2 or 3 predictions for the 50%, 60%, and 90% confidence intervals. For example, my slip-up on predicting Uber wouldn’t have self-driving cars this year means I was only 1 for 2 on 90% predictions. Clearly I need to find more things to predict, as I had 5 and 9 predictions for the 70% and 80% confidence levels, which were right about on the mark. Luckily for next year, I have almost double the number of predictions:

2016 Predictions

How confident should we be? People tend to be overconfident.  One way to figure out if our confidence levels are correct is to test our calibration levels by making predictions and seeing how many of them pan out. Inspired by Slate Star Codex’s predictions, here are my predictions and accompanying confidence levels. For the sake of convenience I will choose from confidence levels of 50%, 60%, 70%, 80%, 90%, 95% or 99%. All predictions are by December 31, 2016 unless noted otherwise.
