Anthropomorphic characteristics of centerfold models: Trends towards slender figures over time
Bibliographic record
Abstract
OBJECTIVE: Anthropomorphic characteristics of centerfold models were analyzed to determine if there has been a trend towards slimmer models over the last 50 years. METHOD: Height and weight, breast, waist, and hip measurements of 559 Playboy centerfold models, obtained from the magazine's website, were analyzed. RESULTS: Regression analyses indicated a gradual and subtle change towards slimness. A latent class analysis yielded five basic types of figures and results indicated that the prevalence of the type of figures being depicted changed over time, with a slightly thinner figure being more common. However, really thin figures were rare until the 2000s and the probability of a model having a body mass index (BMI) < 17 was greater in the 1950s than in the 2000s. DISCUSSION: These findings suggest that there has been a trend towards slimness, but that the changes have been gradual.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
