Polarized profile — 56-point spread from Economy to Institutional Integrity. 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.

ⓘLegacy Rating is the completed-tenure rating derived from sourced leadership dimensions and the recorded conditions of that tenure — on the published scale a score near 60 means the country broadly matched the benchmark trajectory over the mandate. Anything unsourced shows as no data. Full weights on the Methodology page.
SourceWorld Bank GDP + UCDP deaths (annual + Candidate GED) + WGI stabilityMethodCountry-year shock severity · peer-relative damageConfLow✓ ReconstructableⓘCrisis Exposure measures how severely a leader was tested — a peak-biased aggregate of per-year shock severity (conflict intensity, economic contraction and political-stability decline vs. recent normal) over the mandate. It is context, not a verdict: high exposure is neither good nor bad on its own. Crisis Response measures how the country fared during its genuine crisis years relative to comparable crisis episodes worldwide — country-years hit with the same shock severity. Higher = less national damage than peers at that severity. Leaders who never faced a major shock are marked Untested rather than rewarded. Per country-year, real WB/UCDP/WGI shocks are winsorised and percentile-ranked into a ShockSeverity; Exposure is the peak-biased mandate aggregate. Crisis years (severity ≥ 60) score Response = 100 − damage percentile among comparable-severity crises worldwide, then severity-weighted over the mandate. Untested = no major shock (never rewarded). Absent components are reweighted, never filled.

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.

ⓘ
Country scores are the unweighted average of scored World Bank indicators — the same model used on the nation's own page. Difficulty reflects structural constraints on governing this nation, independent of the current leader.
ⓘUp to 5 strengths (dimensions scoring 70+) and 5 weaknesses (scoring 57 or below), ranked from the leadership radar. Dimensions in the 58–69 benchmark band appear in neither column. Descriptions are fixed per dimension and don't vary by country. Dimensions without a sourced signal show as no data. Full model on the Methodology page.
