US Population Aged 65+ vs US R&D Expenditure
US Population Aged 65+ and US R&D Expenditure correlate at r = +0.95 over 28 years (1996–2023), p < 0.0001. With the time trend removed, r = +0.75. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.75). Correlation still isn't causation, but this one isn't an obvious artifact.
