Diagnosticity Analysis

Most Diagnostic Evidence

Evidence Why Diagnostic
SRC01-E01 Deloitte documents sovereign AI motivations in detail but uses a completely different taxonomy than Allganize or KPMG — proving that no single ranked consensus exists (eliminates H1) while confirming substantial documentation (eliminates H3)
SRC04-E01 Adds behavioral governance and model drift prevention as motivations not mentioned in any consultancy survey — demonstrates the motivation space extends beyond what major surveys capture

Least Diagnostic Evidence

Evidence Why Non-Diagnostic
SRC03-E01 KPMG tracks challenges and investment but does not directly address deployment-location motivations, making it supportive but not discriminating between H1 and H2

Outcome

Hypothesis supported: H2 — Multiple surveys document overlapping but non-identical motivation sets. The convergence on security/compliance/sovereignty with divergence on secondary priorities is the clearest pattern.

Hypotheses eliminated: H1 — No single ranked consensus list exists. H3 — Substantial evidence exists from multiple sources.

Hypotheses inconclusive: None
