For the past year, I've been eagerly awaiting the start of 2018. This wasn't out of any dissatisfaction with 2017, or because of any specific events that I expected to happen today. No, I was excited for 2018 because it meant I got to grade my 2017 predictions and make predictions for 2018.
I've found this whole process great fun and would like to try and spread the habit. This post will include my graded 2017 predictions, templates so that you can make your own predictions, my calibration calculations, and my new predictions for 2018.
If you want to be able to look forward to the start of 2019 like I looked forward to today, or if you want to be able to make a cool graph (like this one!)
I recommend trying out my 2018 prediction templates before reading (to avoid being anchored by anything I write). The templates focus on international events and come in two versions:
With both these sheets, the idea is to pick a limited number of probabilities (I recommend 51%, 60%, 70%, 80%, and 90%) and assign one to each item that you have an opinion on. At the end of the year, you count the number of correct items in each probability bin and use that to see how close you were to ideal. This gives you an answer to the important question: "when I say something is 80% likely to happen, how likely, really, is it to happen?"
You can also make your own (or use the set of questions Slate Star Codex normally uses). If you do make your own, please link your post (and maybe also your template?) in the comments or post it to the front page. It's my hope that this post can serve as a convenient place for the LW community to look at the predictions of everyone who wants to participate in this experiment!

I thought that making my predictions mostly numerical would make them easy to grade. This mostly worked, but there were a few edge cases, judgement calls, and other amusing things that I want to explicitly mention:
- Throughout my predictions I used the word "remains". I regret this, because it is ambiguous. I think I intended it to mean "on January 1st, 2018, X remains true", but there's an alternative parsing that is "during all of 2017, X will be true". I feel it's most accurate to grade these according to my intent. For my 2018 predictions, I will use clearler language.
- For 8, the two most recent polls I could find were both from November. In one, Patrick Brown had a "don't know" rating of 50%. In the other, it was 34%. Polls were found by Googling 'ontario leader popularity' and 'ontario leader popularity politics'; November was the last month in which I could find polls, so I only used November polls. I'm averaging these two and considering the prediction successful. The lack of good aggregation of Ontario political information is part of why I would like to create a website tracking the Ontario election this year.
- While I was correct as to the who wasn't the next leader of the Conservative party, I definitely got emotionally involved such that I was severely miscalibrated. Bernier came far closer to winning it then Leitch or Chong and both of those two fringe candidates had much lower chances than it felt like they did.
- WRT 24 and 25, I'm not counting the Las Vegas shooting as a terrorist attack because it lacked a political motive (as far as we currently know). I think I overestimated the risk of terrorist attack because of the availability heuristic (the last two years had seen a higher than normal amount of successful and dangerous terrorist attacks). A proper estimation would have focused more on the base rate.
- I don't think Trump's cancellation of advertising comes anywhere close to fulfilling 29, so I'm marking it as failed.
- 31 is borderline, with many former FARC fighters "joining criminal gangs or a dissident FARC movement that has about 1,000 fighters nationwide". Given that this still implies less than 1000 members rearmed to continue the fight as FARC, I think the prediction holds.
- 38 is also borderline, but ultimately, I think there is a difference between an announcement of intent to move and an actual movement. Since I was going to mark 28 as a success if Trump hadn't signed the tax bill by now, it's only fair that I mark 38 as a failure.
- I was way under-confident in the stability of the Mosul dam (41). Compare my probability with the chance on the Good Judgement Project and you'll see I really overstated the risk compared to the consensus.
- WRT to 43 and 44, the US Treasury added new groups to existing designations, but these are neither new sanctions, nor international sanctions.
- For 59, I think this Daily Mail headline counts: "Thailand's colourful new King brought 'his mistress AND his former air stewardess wife' to his father's lavish cremation ceremony with both marching in bearskin hats". I think I want to stay away from predicting "scandals" in the future though, because it's a very fuzzy concept.
- While North Korea claims to have a complete, miniaturized ICBM, it looks like them actually realizing this with a weapon able to hit the US mainland is about one year away. Therefore 66 is a success.
- 69 is only provisionally true and needs to be revised when more GDP data is available.
- I am apparently rubbish at predicting snap elections, given that I got both 77 and 58 wrong, while being highly confident in my wrongness.
- Out of all of my failed predictions, the one that surprised me the most was the OPEC deal holding. I really thought that it would fall apart.
A complete list of the sources I used when grading all non-personal predictions is available here.
The whole point of having predictions with few allowed probabilities (for me it was 50%, 60%, 70%, 80% and 90%) is that you can then check how accurate these were by pooling your answers. Here's how I did:
- Of my predictions at a 50% confidence level, I got 7 right and 6 wrong (54%).
- Of my predictions at a 60% confidence level, I got 9 right and 4 wrong (69%).
- Of my predictions at a 70% confidence level, I got 16 right and 4 wrong (80%).
- Of my predictions at an 80% confidence level, I got 20 right and 6 wrong (77%).
- Of my predictions at a 90% confidence level, I got 17 right and 2 wrong (89%).
Here's the graph from above again. The red line shows what I would get if I was a perfect judge of probability. The blue line is actual me. Whenever the red line is below my results, I was under-confident. Whenever it's above them, I was overconfident.
I'm pleased that in general (excepting 70% vs. 80%), things I thought were more likely were in fact more likely. I appear to be fairly under-confident at lower probability levels (50% through 70%), and fairly good at higher confidence levels (80% and 90%), although of course this is just one year and some of this could be due to chance and luck.
My meta-calibration was quite poor. I was never more than 10% off from perfect calibration, despite my worries that I would frequently be up to 15% from it.
I tried to keep in mind the results of my calibration while making these predictions. I've also made one slight change. Instead of using 50%, I'm using 51%, which has the implication that whichever way the question is phrased is the way I expect things to be more likely to turn out.
