What the data shows
- Looking back: 87%. Why someone did something (87%), what they needed to do first (87%).
- Looking ahead: 83%. What they'll want to do next (84%), what will happen to them (81%), what will happen to others (81%).
- The gap is small but consistent: 3 to 5 points in favor of looking back.
- Confidence is a bit high. When Jev is 70% to 90% sure, it's right 72% of the time; when it's 99% sure, 98%.
What it means, and what it doesn't
Jev reads people about as well as people do on these questions, and a little better when explaining than when predicting. That fits how it learned: from text that mostly explains what people did after the fact.
It doesn't mean Jev is bad at prediction: 83% is close to the human agreement rate. And some of the gap is noise in the forward-looking answers themselves (see Caveats).
