Luke Muehlhauser — Notable For: Former Executive Director of MIRI; former GiveWell/Open Philanthropy researcher on AI risk

NoteThe claim has two parts: (1) 'Former Executive Director of MIRI' — CONFIRMED by the source text which explicitly states he was 'Executive Director of the Machine Intelligence Research Institute'; (2) 'former GiveWell/Open Philanthropy researcher on AI risk' — UNVERIFIABLE/NOT ADDRESSED. The source mentions his work at Coefficient Giving on global catastrophic risks and AI governance, but makes no mention of GiveWell or Open Philanthropy employment. The source is incomplete regarding the second part of the claim, making the overall verdict 'partial' rather than fully confirmed.
