Public Responses to Policy Reversals: The Case of Mask Usage in Canada during COVID-19
Bibliographic record
Abstract
Coronavirus disease 2019 (COVID-19) has resulted in rapid, substantial, and at times contradictory policy changes as public health agencies and government officials react to new information. We examine the implications of such changes for public compliance by drawing on the case of revised guidance on mask usage by asymptomatic individuals. As official recommendations on the use of masks in Canada shift from discouraged to mandatory, we draw on findings from an ongoing public opinion study to explore contemporaneous changes in rates of mask adoption and levels of public trust in government institutions. We find that Canadians exhibit high levels of compliance with changing policies on mask usage and that trust in public health officials remains consistent despite policy change.

Full frame machine prediction
Teacher imitationNot 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.
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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
