Abstract

fetched live from OpenAlex

Eyewitnesses typically communicate identification confidence to law enforcement in their own words. Despite a positive confidence-accuracy relationship when confidence is measured numerically (and identifications uncontaminated), there is no clear basis for determining whether oft-ambiguous verbal phrases indicate low, medium, or high confidence. Participants indicated which percentages they associate with low, medium, and high confidence or judged whether percentages signal low, medium, and high confidence. They also provided numeric interpretations of verbal phrases. Laypersons considered 80%+ as high confidence and the level of confidence they believed was intended with words and numbers varied considerably. Miscommunications about eyewitness confidence may be common.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
