Predictions for 2021
January 11, 2021
Making predictions for the year seems like a good beginning-of-the-year tradition, so I’m trying it out. My evaluation criterion for these predictions will be their Brier score, where I interpret the score roughly as follows:
- > 0.25: Bad (worse than predicting 50% for everything)
- 0.20-0.25: Okay
- 0.15-0.20: Good
- < 0.15: Excellent! (my expected score if all these predictions are perfectly calibrated is about 0.17)

Hard to operationalize2, but I expect it to be pretty obvious. ↩︎
Attempt: there is evidence of its presence in >20 states, and there are more than 2.5M confirmed cases per week in the US at its peak, sometime between March and June. ↩︎
A decline of at least 20% from the peak. ↩︎
I did run 5k in 28 minutes in 2018, but I haven’t been running recently. ↩︎
My current best is 10.687. ↩︎
It can consistently resolve in either direction, or it is inconsistent no matter which direction it resolves. ↩︎
