NoteThe source confirms all key fields: person (Catherine Olsson), org (Anthropic), and role (Member of Technical Staff, Interpretability). The source is from August 2022, which is consistent with a startDate of 2021-01 (she would have been in the role for ~1.5 years by the time of the podcast). The only field not directly addressed is the specific startDate of 2021-01, which is unverifiable from this source but not contradicted—the source confirms her status as of 2022 in this role, which is consistent with a 2021 start date.
