Outlook
Structurally Constrained
Can this leader deliver on its agenda?
Structural constraints likely outweigh this leader's demonstrated capability. The severely constrained domestic structural context coincides with severely adverse external conditions (5/100).

Weighted average
ConfMedium
✓ Reconstructable
ⓘLeadership Rating measures change under the leader relative to global trends — a score near 60 means performance broadly matched the benchmark trajectory. It is a weighted average of up to eight dimensions, renormalised over the ones with sourced data (the coverage note beside the score says how many), and requires all four core dimensions — Governance, Economy, Politics and Institutional Integrity — to be sourced. Five use live World Bank indicators; the rest are derived from sourced signals (WIPO/Oxford/UNESCO, GDELT, World Bank + UCDP, survey data) where coverage exists. Diplomacy is a GDELT-derived engagement proxy, and anything unsourced shows as no data. Political position is V-Dem V-Party expert coding. 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.

Economy derives from World Bank indicators; Institutional Integrity from V-Dem's executive-corruption index (World Bank Control of Corruption as fallback); Communication from GDELT media reach, tone and resilience; Crisis Exposure and continuity from the stability blend. A low Communication signal can mean thin coverage OR wide-but-hostile coverage — the flag distinguishes the two.
