RQ19: How do educational quality (school funding history), English proficiency, numeracy skills, previous healthcare navigation experiences, material adequacy (patient education materials at appropriate reading level), provider communication clarity, and health system complexity predict health literacy scores and healthcare navigation success?
RQ20: Why is life expectancy 4 years lower for Black Americans than White Americans?
RQ20: How do cumulative exposures across the lifecourse—including childhood poverty duration, educational quality, occupational hazards, environmental racism (air/water quality), healthcare quality and access, chronic stress (measured via allostatic load), neighborhood safety, housing quality, and social capital—predict longevity across birth cohorts and geographic regions?
OLD PARADIGM assumptions:
Race is a valid, measurable category
Racial groups are internally homogeneous
Differences between races are meaningful
Race can serve as proxy for unmeasured factors
Comparing racial averages produces interpretable results
NEW PARADIGM (Williams) requirements:
Measure actual exposures and mechanisms
Account for within-group heterogeneity
Specify causal pathways explicitly
Use validated measurement tools
Consider historical and structural contexts
Avoid crude categorical comparisons
Test specific hypotheses about mechanisms
Ensure reliability and validity of all measures
The difference: OLD asks "Do races differ?" NEW asks "What specific, measurable factors cause health differences across populations, and how do they operate?"
