Abstract
According to D. Kimura's (2000) interpretation of the hunter-gatherer hypothesis, men are better at targeting tasks and women are better at fine-motor tasks because of their evolutionary experiences. The author applied that hypothesis to a lower limb pointing task, a task uninfluenced by hunting and gathering experience throughout history. Participants (39 women, 35 men) completed the P. M. Fitts (1954) task by using both their dominant right hand and foot. Results suggested that for both the upper and lower limbs, men move faster, particularly for the more difficult tasks. The hunter-gatherer hypothesis does not predict those data; rather, linear regression data suggest that gender differences in movement strategies affect motor performance. The author proposes that men and women preferentially adopt distinct strategies emphasizing speed for men and accuracy for women.

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
