Abstract

fetched live from OpenAlex

Introduction: It is a positive indicator that human lifeexpectancies calculated from birth have been increasing. The current standards for counting life-years, however, assume social desirability and exclude all prenatal deaths. These assumptions mask low life-year deaths and obscure results of medical and environmental interventions, thus falsely indicating higher life expectancies.Aim: To quantify the life expectancy with and withoutsocial desirability.Methods: This case study investigates 1930 to 2016 using CDC and World Bank data for the U.S. for the impact of social desirability on life expectancy.Results: It is evident, published U.S. life expectancies are greatly exaggerated and what would have beenshort-lived Americans are disproportionately labeled as socially-undesirable and ignored when counting life years, thus presenting an overly-optimistic view of U.S. health.Conclusions: A comprehensive global investigation isneeded, and a refinement of life expectancy calculationsshould be introduced, which does not bias results by only counting life expectancy from the time of live birth.

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.

Not 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.
