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 three of the four components of the claim: (1) Hubinger's co-authorship of the 2019 paper introducing mesa-optimization is verified; (2) deceptive alignment is discussed in Section 4 as stated in the claim. However, the source does not address: (1) the 'Sleeper Agents' research attribution; (2) the 'Alignment Faking' research attribution; (3) the citation count of 3,400+ as of 2026-03. The arXiv excerpt provided is the paper itself and contains no citation metrics. The claim about Anthropic leadership roles and citation counts cannot be verified from this source alone.
