US Annual Working Hours per Worker vs US Cereal Yield
US Annual Working Hours per Worker and US Cereal Yield correlate at r = -0.76 over 63 years (1961–2023), p < 0.0001. With the time trend removed, r = +0.25. 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 0.25 — the relationship is probably coincidental, not causal.
