Polarized profile — 52-point spread from Economy to Vision. No archetype rule matches that shape. This is a reading of the sourced stats — not a data gap.
SourceDerivedMethodRule-based classificationConfDeterministic✓ ReconstructableⓘArchetypes are derived automatically from the leadership stat profile — not hand-assigned. "No distinct archetype" means no classification rule matched; profile shape is assessed separately from the best-to-worst spread. A leader lacking enough sourced stats reads as "No data". A secondary archetype is added only when a stat scores exceptionally high.

Source: World Bank + derived·Method: Contribution·✓ ReconstructableⓘEach dimension measures change under the leader relative to global trends — how the indicator moved over their tenure, net of the world's move over the same window — not the country's absolute level. A score near 60 means performance broadly matched the benchmark trajectory; above = improved the country's standing, below = declined. Governance / Economy / Politics / Institutional Integrity from World Bank WGI, WDI and V-Dem trajectories; Vision from the country's innovation rank (WIPO patents + UNESCO tertiary), former leaders only (patents lag ~3 years); Crisis Response (World Bank + UCDP + WGI, an absolute response-quality scale) and Communication (GDELT) from tenure signals; Diplomacy (Diplomatic Conduct) is active-only. A tenure under six months, or an indicator whose series hasn't reached the term, shows as no data. Full model on the Methodology page.
