Holden Karnofsky — Birth Year: 1981

NoteThe Wikipedia article explicitly states in both the infobox and the opening paragraph that Holden Karnofsky was 'Born 1980 or 1981'. The claim states his birth year is 1981, which falls within the source's stated range of 1980 or 1981. Since the source provides a range that includes 1981, the claim is confirmed. The additional context 'Born approximately 1981' aligns with the source's uncertainty (1980 or 1981).
