Institutionalist
Governance through rules, process, and precedent. High governance and institutional integrity scores define this profile — a leader who strengthens institutions rather than uses them, often at the cost of short-term agility.

ⓘ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.

ⓘ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.

Source: World Bank WGI + V-Dem + derived·Method: Stewardship·✓ ReconstructableⓘMeasures whether strong institutions inherited at the start of the tenure were preserved, improved or eroded. It does not reward the leader for inheriting a strong country. A metric qualifies only when the inherited baseline was at least 75 on its normalized scale; the score is the world-net change over the tenure on the single public scale (60 = preserved relative to global movement). Requires two or more eligible sourced groups, the six-month tenure floor and a post-tenure-start observation — otherwise No data, never a zero. Weights mirror the current-form groups (gov 0.17 · pol 0.15 · int 0.08 · vis 0.09), renormalized over what is eligible and sourced.

ⓘ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.
