US Electricity Generation vs US Resident Patent Applications
US Electricity Generation and US Resident Patent Applications correlate at r = +0.89 over 37 years (1985–2021), p < 0.0001. With the time trend removed, r = +0.13. Likely spurious (shared time trend).
Verdict: Likely spurious (shared time trend). Both series mostly just trend over time. After removing that trend the correlation collapses to 0.13 — the relationship is probably coincidental, not causal.
