: He contends that a 10% increase in excess deaths is typically a once-in-200-year event; thus, a 40% jump represents an "earth-shaking" anomaly.

: Dowd frequently cites public disclosures from the CEO of OneAmerica insurance, stating that death rates among working-age individuals (ages 18–64) rose by 40% in late 2021 compared to pre-pandemic levels.

: Dowd's primary thesis is that the introduction of mass COVID-19 vaccination campaigns and employment mandates in 2021 is the only major variable that changed to account for this sudden spike.
