Abstract

fetched live from OpenAlex

The Trivers-Willard Hypothesis posits that parents in favorable conditions tend to invest more in male offspring, while those in disadvantaged conditions focus on female offspring under the disadvantaged condition based on the reproductive potential of the next generation. Through a review of previous studies, we find that these series of studies lack a unified measurement to assess parental socioeconomic status and parental investment, which may be the cause of inconsistent results. To solve this problem, our study establishes a cross-culturally applicable measurement framework. By measuring the annual household income, the income distribution ratios and time investment differences between children of different sexes, we aim to validate the Trivers-Willard Hypothesis. Even if there are possible negative results in future studies, our measurement still contributes to enhancing methodological homogeneity in future research.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
