Sunspot Number vs US Resident Patent Applications
Sunspot Number and US Resident Patent Applications correlate at r = -0.43 over 42 years (1980–2021), p = 0.0043. With the time trend removed, r = +0.24. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0043) and the association survives trend removal (detrended r = 0.24). Correlation still isn't causation, but this one isn't an obvious artifact.
