Abstract

fetched live from OpenAlex

We thank Harper & Palayew for replicating our analysis of traffic risks on April 20.1 2 We agree that the absolute risks on April 20 must be modest because the majority of Americans do not celebrate the ‘high holiday’ and because comparison days are not devoid of impaired driving. Similarly, secular trends in relative risks for April 20 reflect evolving driving norms, fluctuating traffic enforcement, changing baseline rates of cannabis use, variable celebration behaviours and rapid growth of the cannabis industry. We also agree that crashes are already recognised to be more frequent on traditional holidays such as Independence Day and Thanksgiving.3 Beyond this shared understanding, however, we disagree with Harper & Palayew on a key assumption in their analysis.

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.
