Abstract
Government regulators and consumer packaged goods companies around the world struggle with methods to help consumers make better nutritional decisions. In this research we find that, depending on the consumer, a traffic light color-coding (TLC) approach to product labeling can have a substantial impact on perceptions of foods' health quality and food choice. Across 3 lab experiments and a field experiment, we find that TLC labels provide nondieters with an information processing cue that directly influences evaluations in a manner that is consistent with the "stop" and "go" logic behind the traffic light labels. In contrast, we find that dieters do not simply adopt the red, yellow, and green cues into their health quality evaluations. Instead, regardless of the color, the TLC approach increases the depth at which dieters process label information. Dieters tend to focus on the costs of consumption and, as a result, lower their health quality evaluations. In a field study, measuring actual behavior in a grocery store, health quality evaluations predicted consumption and consistent with the color coding of the labels nondieters consumed the most when they were presented with a predominantly green label.

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 it
