Abstract
Synchronization of behavior has repeatedly been shown to increase pain threshold, which is understood to be an indicator of endorphin activity. Although Weinstein et al. found that large and small groups showed the same effect, to date no study has manipulated group size to determine if it has an effect on change in pain threshold. Thirty-three participants rowed two 20-min time trials under two counterbalanced conditions—paired and large group. Pain threshold was assessed before, immediately post, 5-min post, and 10-min post each session. A repeated-measures (3 × 2) factorial ANOVA revealed a significant interaction between condition and time. Specifically, there was a significantly higher pain threshold in the large group than in the paired condition after 10 min of exercise.

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
