# Limitations

## Human reference limitations

- DSE references are aggregate published point estimates, not microdata.
- Human confidence intervals cannot be computed from the available material.
- Samples and subgroup estimates are not equivalent.
- The source book contains an unresolved internal discrepancy for the Swiss
  family result.
- MFQ references are 19 national means with incomplete row-level provenance in
  the current package.

## Instrument limitations

- DSE vignettes are reconstructed from the published design.
- The model task fixed CHF 18,000, whereas the source design varied the sum.
- Public questionnaires may have appeared in model training data.
- Human-validated psychometric constructs may not transfer invariantly to
  language models.

## Design limitations

- The active release is cross-sectional.
- The DSE covers two settings and one amount.
- Repeated generations characterize output variability; they are not human
  participants.
- Model intervals do not cover new prompts, dates, tasks or versions.
- No independent human methodological audit or peer review has been completed.

## Interpretation limitations

- Hypothetical outputs are not real-world behaviour.
- A model point inside or outside aggregate human estimates does not establish
  representation.
- Equal splitting alone does not identify a single egalitarian motive.
- Differences between exact configurations do not imply effects of developer
  country or model family.
