The detection of deception during trials: Ignoring the nonverbal communication of witnesses is not the solution—A response to Vrij and Turgeon (2018)
Bibliographic record
Abstract
In their paper ‘Evaluating credibility of witnesses—Are we instructing jurors on invalid factors?’, Vrij and Turgeon (2018) argue that jurors should be advised not to consider demeanour when trying to evaluate if witnesses are honest or dishonest because of ‘overwhelming scientific evidence’. However, in this response, we contend that substantial empirical scientific studies on nonverbal communication alongside the limitations of deception detection research, as cited by Vrij and Turgeon (2018), undermine their overall argument. While jurors should be warned about erroneous beliefs and dubious concepts on human communication, jurors should also be advised to consider demeanour as a way of enriching their overall understanding of witnesses and their verbal testimony.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
