US Homicide Rate vs US Cereal Yield
US Homicide Rate and US Cereal Yield correlate at r = -0.67 over 31 years (1990–2023), p < 0.0001. With the time trend removed, r = +0.02. 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 0.02 — the relationship is probably coincidental, not causal.
