US personal income per capita is 10 times higher than a hundred years ago.
Unresolvable The public record could not settle it.
Factual: Statements about the present or the past, checked against the record: did they hold up?
The second judge would not resolve this claim; the verdict shown is the first judge's.
What would count as true or false
Judge the numeric claim that US personal income per capita is 10 times higher than a hundred years ago. True if, on a consistent real (inflation-adjusted) basis over ~100 years, US real personal income per capita is about 10 times higher. If Kurzweil meant real terms and the data show roughly 10x, true; mostly true if close (e.g. 8-12x). Mostly false if a real figure underlies it but materially differs (e.g. the claim conflates nominal and real, or the true multiple is far from 10). False if wrong outright.

Reasoning
The evidence gives multiples of more than five since 1929 [E2] and about 6.6 from 1930 to 2022 [E3], but the quoted material does not show that either is an inflation-adjusted personal income measure. The real series gives only a 2024 value [E1], and the inflation-adjusted table gives no figures [E4], so the evidence does not establish the real multiple over about 100 years that the criteria require.
