2021 Predictions Review

January 4th, 2022

Now that it’s 2022, I’ve scored my 2021 predictions. To get slightly bigger samples, I inverted the prediction and predicted probability of <50% predictions—e.g. “Democrats win both Georgia seats: 25%” became “Democrats do not win both Georgia seats: 75%” for scoring purposes.

Predicted Probability Actual Probability
90+% 89%
80-89% 75%
70-79% 63%
60-69% 58%
50-59% 67%

I was a little overconfident across the board, but this actually lined up a lot better than I thought it would:
