Abstract

fetched live from OpenAlex

Real-world food label reading is examined in two laboratory tasks to evaluate the role of cognitive factors in peoples’ willingness and ability to follow therapeutic diets. Participants were asked to repeatedly make decisions about the safety of foods that did or did not contain specified allergen targets; each of 30 foods were presented 15 times in randomized and intermixed orders. At each presentation the safety judgement could be made with or without consulting the food ingredient label. The results imply limitations to reading accuracy, learning, and judgements about that learning. Most participants became less likely to read ingredient lists over time, suggesting that decisions to read is driven by cost-benefit. The findings suggest that despite the improvements to food label formats, people probably choose not to read them as often as they should and will miss seeing target ingredients when they do.

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.
