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 is the ProPublica Nonprofit Explorer page for MIRI's 990 filings, which is the correct source document. However, the source text provided shows only the 'Key Employees and Officers' compensation section, which lists 14 named individuals (with a '+ View more people' indicator suggesting additional entries exist). The source does not explicitly display a total headcount count of 28 in the excerpt provided. While the additional context notes that MIRI's own 2023 review reports ~18 staff and suggests the 990 figure may count employees who departed during the year, the actual 28-employee figure from the 990 form itself is not visible in the provided source text. To verify the exact headcount, one would need to access the full Form 990 Schedule J or other sections that typically report employee counts, which are not included in this excerpt.
