PREFERENCE FOR A FIRST-BORN BOY IN WESTERN SOCIETIES
Bibliographic record
Abstract
Many studies in the last 45 years have shown that women prefer a boy to a girl for their first-born child, suggesting that this preference is universal in Western societies. A careful examination of these studies reveals, however, that the subjects were often women who were not pregnant and/or students. A review of sixteen studies with first-time-pregnant women showed that in most cases the opposite was true, namely, that a girl was desired more often than a boy, especially during the last two decades (from 1981 to 1996). Data concerning expectant fathers, however, indicate that they prefer a boy rather than a girl. A preference for a boy first was also observe for both non-expectant males and females. Women's preference for a male child decreased and men's preference increased slightly when the two sub-periods (before 1980vs after 1981) were compared. A difference between men and women is, however, evident whatever the sub-period: men more often prefer a boy than women. These findings suggest that something specific about being pregnant is related to the preference for a girl first.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
