Our reading of the claim

Reference (stated reasonable reading)

Wrong / missed

Criterion: Ordinary population life expectancy/expected lifespan exceeds 100 years, not a few individuals living past 100.

Deadline: 2019 · Included in this comparison

At original deadlineNOT FULFILLED
By review dateNOT FULFILLED

Observed 2019 US life expectancy was 78.8 years, far below 100. CDC’s 2024 estimate is 79.0 years. Cohort hopes or exceptional centenarians do not establish ordinary life expectancy over 100.

Deadline and follow-up notes

At deadline: Observed 2019 US life expectancy was 78.8 years, far below 100.

By review: CDC’s 2024 estimate is 79.0 years. Cohort hopes or exceptional centenarians do not establish ordinary life expectancy over 100.

Capability, adoption, and timing

A related breakthrough is not automatically fulfillment. Review must check the actual capability, how widely it was required to be used, the specified technology, and the original deadline. A prototype cannot establish a claim about routine or widespread use.

Research notes & history

Period life expectancy is the reference measurable interpretation. A forecast about an unspecified future cohort would need its own model; it is not evidence of present achievement.

Review history

— Evidence v0.2: WRONG_MISSED. Final US life expectancy was 78.8 in 2019 and 79.0 in 2024. Even this high-income-country example does not support the general claim. The judgment is explicitly under the conventional period-life-expectancy reading. Change: Complete deadline/current outcome assessment under explicit scope; separate uncertainty from verdict.

— Evidence v0.3: EDITORIAL_ASSESSMENT_COMPLETE; supplied verdict WRONG. Observed 2019 US life expectancy was 78.8 years, far below 100. CDC’s 2024 estimate is 79.0 years. Cohort hopes or exceptional centenarians do not establish ordinary life expectancy over 100.
