Abstract
This study examines whether loneliness explains the association between perceived everyday discrimination and depressive symptoms among older adults as well as whether this indirect pathway differs by education. Three waves (2006, 2010, and 2014) of the Health and Retirement Study ( N = 7,130) are analyzed with random-effects models that adjust for repeated observations and fixed-effects models that control for all time-stable influences. Everyday discrimination is associated with loneliness and depressive symptoms but more weakly in fixed-effects models. The association between discrimination and loneliness is stronger at low educational attainment, leading discrimination to be indirectly associated with depressive symptoms through loneliness only at low education. The consequences of everyday discrimination for depression in late life are limited to older adults with low education due to education-contingent associations with loneliness. Perceived discrimination may have broad health consequences through loneliness, especially for older adults at low education.

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
