Abstract

fetched live from OpenAlex

One-hundred twenty-eight undergraduates were shown a videotape of a staged crime of a young man abducting a child. Participants were instructed to role-play eyewitness behaviors in which they (a) lied to protect the perpetrator; (b) lied to protect the perpetrator but told the truth about the child; (c) lied to ensure the conviction of the perpetrator; or (d) responded truthfully and accurately to the best of their ability. One week later, participants were given a target-present or target-absent photo lineup of both the perpetrator and the child-victim. Participants instructed to lie to protect the perpetrator consistently stated he was not present as opposed to selecting an innocent person. In addition, participants lying to protect the perpetrator were significantly quicker to make identification decisions than participants attempting to make an accurate identification. There were no significant differences between groups in identification performance or in decision times involving the child lineup.

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.
