What it is
Runs Jev and GPT-4.1 as 300 synthetic survey respondents on Twin-2K-500, comparing probability elicitation methods for survey research.
How it uses Jev
Jev answers yes/no questions as Noul (single probability) and multi-option as Choice. Its probability vector is compared to GPT-4.1's verbalized probabilities on distribution gap, calibration, Brier, and accuracy.
Primitives:choicenoul
Technique worth stealing
Asking yes/no items as Noul instead of Choice moves results more than model choice.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
