The regressions identified correlations rather than causal mechanisms. Most analyses excluded deaths before age 10 because of concerns about infant and child mortality reporting. The dataset was limited by missing data, privacy restrictions, user-contribution bias, and incomplete or inaccurate records. The U.S.-focused machine-learning task does not generalize directly to all countries, modern cohorts, or people dying earlier in life. Infant and child mortality were likely misreported or underrepresented in the genealogy data.
