Abstract
Peer antisocial behavior robustly predicts adolescents' own behavior, but not all adolescents are equally vulnerable to their peers' influence and genetic factors may confer vulnerability. This study used data of n = 3,081 adolescents from the A von L ongitudinal S tudy of P arents and C hildren to examine whether brain‐derived neurotrophic factor ( BDNF ), a polymorphism that affects psychological functioning, moderates the association between affiliation with aggressive peers at age 10 and own aggression at age 15. A significant gene–environment interaction was found, where those who affiliated with aggressive peers in childhood showed increased risk of being aggressive in adolescence if they carried the BDNF met‐met variant compared with val‐val carriers. Our findings underline the importance of both biological and social factors for adolescent development.

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
