Saudi-linked individuals knowingly facilitated Nawaf al-Hazmi and Khalid al-Mihdhar
Testable proposition: one or more people linked to Saudi official structures (Bayoumi, Thumairy, others) provided assistance to Hazmi and Mihdhar with knowledge that the assistance served al-Qaeda's operational purpose, not merely with knowledge that two Saudis needed housing. 'Knowingly' is the load-bearing word. Split internally into (a) tasked settlement assistance and (b) knowledge of the 9/11 plot.
Likelihood — more or less than 50%
70%
More than 50% — supported by the sources
Start at 50%. Move by half of the net source score after uncertainty. Net source score is 0.51 (from −1 contradict to +1 support). Uncertainty is 22%. So 50% + 50% × 0.51 × 78% remaining certainty = 70%.
0.5 + 0.5 × 0.51 × (1 − 0.22) = 0.699

Piers Robinson — Researching 9/11 and Beyond: Current Knowledge and Future Directions (Aug 2024)
Journal of 9/11 Studies · 2024-08-01
Robinson's 2024 survey cites Harrit 2009, Hulsey 2020, MacQueen eyewitness counts, NIST NCSTAR, the Commission, Ashton v KSA, and a 2023 Klarenberg claim of a CIA-Saudi recruiting operation involving two hijackers.
