twin2k_gpt41mini_synthetic.csv against twin2k_wave4_human.csv

Precomputed example on public data (Twin-2K-500: human respondents against GPT-4.1-mini synthetic respondents). It is shown for illustration; it is not a verdict on any vendor.

Scope: 87 single-select or ordinal questions scored from 2,058 synthetic and 2,058 human respondents. The two files are compared as answer distributions, not respondent by respondent.

Use synthetic 17 17 from your human data, 0 from the ranker alone
Spot-check with humans 23 23 from your human data, 0 from the ranker alone
Field with humans 47 47 from your human data, 0 from the ranker alone

87 questions scored, 91 not scored (multi-select, open text, set aside for review, and similar). 87 have enough human answers to compare directly (human n at least 50); the rest are ordered by the ranker, which ranks and does not give probabilities.Bins marked "ranker only" are provisional.

Not scored: demographic and screening variables (5)

These columns describe respondents or the sample, not survey questions, so they are not audited. Add column names to config.exclude to leave out others.

How the ranker fares on your data

On 87 questions where your human data allows a direct comparison, 67% exceed the failure threshold. The ranker, which sees only the synthetic answers, orders them with an AUC of 0.91 (0.5 is chance, 1.0 is perfect) and the top fifth of its ranking contains 1.50 times the failure rate of a random fifth. With your human answers added as an audit sample, AUC is 1.00.

If your files contain the Twin-2K-500 study, the figure above is in-sample for the ranker and optimistic. The out-of-sample figures are below.
Published evidence for the rankerROC AUC
Twin-2K, synthetic answers only, question families and respondents held out0.802
Twin-2K, plus a 10% human audit0.883
GSS, frozen Twin-2K model, no refit (10 question families)0.752 [0.554, 0.893]

The ranking transferred to a second study; its probabilities did not (calibration error 0.178 on GSS). This report therefore uses ranks and never shows a probability.
