Establish external validation in the brand-recommendation domain

Establish whether the Dice Roll Method’s domain-specific effect sizes, iteration thresholds, and other brand-recommendation findings generalize to independently collected repeated-query brand-recommendation data.

Background

The external validation uses independent corpora from political-orientation testing and benchmark-accuracy studies because no public repeated-identical-prompt brand- or product-domain corpus from another research group is available.

The statistical machinery transfers across the external corpora, but the authors explicitly distinguish that result from validation of the protocol’s brand-recommendation-specific effect sizes and thresholds. Independent brand-domain evidence is therefore still needed to address the paper’s evidential circularity.

References

External validation therefore runs out of domain and tests the statistical machinery (variance components, iteration requirements, generalizability projections, drift diagnostics); brand-domain external validation remains open, as Section~\ref{sec:limitations} records.
