MODELING EFFECTS IN STUDENT DRINKING AND SMOKING, REVISITED AFTER 24 YEARS
Bibliographic record
Abstract
A systematic replication is reported of a campus survey carried out in 1978. The present data (N = 100) indicate increased peer modeling effects for drinking, in which a respondent's intake of alcohol and drunkenness are both best predicted from the drinking of his/her friends. Smoking, however, today shows no correlation with the smoking of either friends or parents, unlike the previous survey. Alcohol consumption, measured as drinks per week, has remained constant over 24 years for female students, but has doubled for males, reaching four times the female level. The frequency of drinking “to excess” also increased greatly over this interval. Smoking has decreased to minimal levels, and now shows no sign of modeling effects, but self-serving bias now occurs, since respondents today report themselves as smoking fewer cigarettes than their friends.

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.
