US GDP per Capita vs US Resident Patent Applications
US GDP per Capita and US Resident Patent Applications correlate at r = +0.97 over 42 years (1980–2021), p < 0.0001. With the time trend removed, r = -0.01. 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 -0.01 — the relationship is probably coincidental, not causal.
