US Inflation Rate vs US R&D Expenditure
US Inflation Rate and US R&D Expenditure correlate at r = +0.39 over 28 years (1996–2023), p = 0.039. With the time trend removed, r = +0.48. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.039) and the association survives trend removal (detrended r = 0.48). Correlation still isn't causation, but this one isn't an obvious artifact.
