Machine Intelligence Research Institute (MIRI) — Headcount: 28

NoteThe claim states MIRI had 28 employees as of 2023 based on IRS Form 990 data. The source text provided is from ProPublica's Nonprofit Explorer and displays the 2023 Form 990 filing with detailed compensation information for key employees and officers. However, the extracted text does not include a field explicitly stating total headcount or number of employees. The source shows 14 named individuals in the compensation section (with a '+ View more people' indicator suggesting additional staff), but does not provide the total employee count. The claim's additional context notes that MIRI's own 2023 review reports ~18 staff, suggesting the 990 figure may count employees who departed during the year. Without access to the full Form 990 Schedule J or other sections that typically contain employee count data, the exact headcount of 28 cannot be verified from the provided excerpt. The source is relevant and about the correct entity, but the specific data point (total headcount = 28) is not explicitly stated in the provided text.
