US Internet Usage vs Sunspot Number
US Internet Usage and Sunspot Number correlate at r = -0.34 over 35 years (1990–2024), p = 0.048. With the time trend removed, r = -0.12. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.048) and the association survives trend removal (detrended r = -0.12). Correlation still isn't causation, but this one isn't an obvious artifact.
