Abstract
Sensation seeking is the tendency to seek out new and thrilling experiences and to take risks for the sake of such experiences. A single-nucleotide polymorphism, -521 C/T (rs1800955) in the promoter region of the dopamine-4-receptor gene (DRD4), is associated with approach-related traits including novelty seeking and extraversion, in some, but not all studies. To our knowledge, no studies have been conducted on the genetics of risk-taking behavior in sports. Using a joint-analysis approach, we measured sensation seeking in two cohorts of experienced male and female skiers and snowboarders (n = 503) using a sports-specific tool developed for this study, the Contextual Sensation Seeking Questionnaire for Skiing and Snowboarding (CSSQ-S), and a more general trait measure, the Zuckerman-Kuhlman Personality Questionnaire impulsive sensation-seeking subscale. We detected, and then replicated a significant association between the DRD4 -521CC genotype and sports-specific sensation seeking as measured using the CSSQ-S (P < 0.001). These data suggest that the DRD4 -521 C/T polymorphism contributes to a "risk-taking phenotype" in skiers and snowboarders, but the variant was not associated with impulsive sensation seeking (P = 0.9).

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
