Abstract
Additional file 1: Table SM.1. Expected (based on population) versus actual count of households receiving postcards. Fig. SM.1. “COVID Specific” postcard design. Fig. SM.2. “General Health” postcard design. Table SM.2. Descriptive characteristics of study sample by postcard type. Table SM.3. Likelihood of Agreeing with the statement: “Getting sick with COVID-19 can be serious.” Table SM.4. Likelihood of Agreeing with the statement: “I will probably get COVID-19.” Table SM.5. Likelihood of Agreeing with the statement: “The threat posed by COVID-19 is exaggerated by the Canadian federal government.” Table SM.6. Likelihood of Agreeing with the statement: “COVID-19 will NOT affect many Canadians.”.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
