MacArthur Foundation — Founded Date: Jan 1978

NoteThe source directly states the MacArthur Foundation's inception date as '6 January 1978'. The claim specifies '1978-01' (January 1978), which matches the month and year of the source's date. The source provides a more precise day-level date (January 6), but the month-level precision in the claim (1978-01) is consistent with and confirmed by the source. Date precision differences (day-level vs. month-level for the same month) are not contradictions.
