Updated: August 17, 2022
At the beginning of every year, I make predictions. At the end of every year, I score them (this year I’m very late). Here are 2014, 2015, 2016, 2017, and 2018.
And here are the predictions I made for 2019. Strikethrough’d are false. Intact are true. Italicized are getting thrown out because I can’t decide if they’re true or not. All of these judgments were as of December 31 2019, not as of now.
Please don’t complain that 50% predictions don’t mean anything; I know this is true but there are some things I’m genuinely 50-50 unsure of. Some predictions are redacted because they involve my private life or the lives of people close to me. A few that started off redacted stopped being secret; I’ve put those in [brackets].

50% predictions are technically meaningless since I could have written them either way. I’ve lightened them on the chart to indicate they can be ignored.
It was another good year for me. Unlike past years, where I erred about evenly in both directions, this year I was about 4% underconfident across the board. I’m not sure how much I should adjust and become more confident. In past years I’ve been burned by major black swan events that affect multiple predictions and made me look overconfident. In 2019 I tried to leave a cushion for that, but nothing too unexpected happened and I ended up playing it too safe. My worst failures were underestimating Bitcoin (but who didn’t?) and overestimating SpaceX’s ability to launch their crew on schedule. I didn’t check formally, but there doesn’t seem to be much difference in my calibration about world affairs vs. my personal life.
I forgot to make predictions for 2020 until now, which in retrospect was the best prediction I’ve ever made. I’ll probably come up with some later this month.
