Evan Hubinger — Notable For: Co-authored Risks from Learned Optimization (2019) introducing mesa-optimization and deceptive alignment; led Sleeper Agents and Alignment Faking research at Anthropic; 3,400+ citations

NoteThe source directly confirms two key elements of the claim: (1) Hubinger's co-authorship of the 2019 paper introducing mesa-optimization and deceptive alignment, and (2) the paper's publication date and content. However, the source is the paper itself and does not address: the Sleeper Agents and Alignment Faking research at Anthropic, or the citation count (3,400+ as of 2026-03). The citation count cannot be verified from this source—it would require checking a citation database as of March 2026. The Anthropic affiliation and other research projects are not mentioned in this paper excerpt. Therefore, the claim is partially confirmed but substantially unverifiable from this single source.
