Rob Wiblin — Director of Research & Host at 80,000 Hours

The provided source text is the 80,000 Hours homepage, which discusses the organization's mission, career guide, problem profiles, and advising services. It does not contain any personnel information about Rob Wiblin, his position as Director of Research & Host, or when he started at the organization. While the source confirms that 80,000 Hours exists as an organization, it provides no information to verify or contradict the specific personnel record claims. This is a case of wrong source relevance — the source discusses the organization itself but not its personnel roster.
