Evaluation of model bias using the Persona Engineering Persona A dataset, reporting PSI and Volatility scores.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Persona Bias Evaluation |
| Dataset (including any stated split) | Persona Engineering Persona A |
| Metric | PSI |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 5 of 5 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [PSI](<https://www.sota2.com/research/sota/persona-bias-evaluation-on-persona-engineering-persona-a.md?metric=PSI>): Lower is better; unit: SCALAR.

- [Volatility](<https://www.sota2.com/research/sota/persona-bias-evaluation-on-persona-engineering-persona-a.md?metric=Volatility>): Lower is better; unit: SCALAR.
