Science or pseudoscience? A distinction that matters for police officers, lawyers and judges
Bibliographic record
Abstract
Scientific knowledge has been a significant contributor to the development of better practices within law enforcement agencies. However, some alleged 'experts' have been shown to have disseminated information to police officers, lawyers and judges that is neither empirically tested nor supported by scientific theory. The aim of this article is to provide organisations within the justice system with an overview of a) what science is and is not; b) what constitutes an empirically driven, theoretically founded, peer-reviewed approach; and c) how to distinguish science from pseudoscience. Using examples in relation to non-verbal communication, this article aims to demonstrate that not all information which is presented as comprehensively evaluated is methodologically reliable for use in the justice system.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
