Diplomatic Conduct 77/100 (medium confidence) — performance-under-test blend from directed GDELT events + UCDP. Governing-stability conditions score 60/100, renormalised over WGI, V-Dem and UCDP.
The risk read
For country-risk purposes, John Mahama's tenure reads as moderately stable: governing-stability conditions score 60/100. Crisis exposure 7/100 (Minimal exposure); response untested. For the full opportunity, market-pulse and resilience read, see Ghana's nation page.

✓ 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.

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.

Current Challenges
Governance Accountabilityhigh
Institutional Integrity score of 25 reflects persistent accountability pressures that constrain institutional effectiveness.
Source: Derived·Method: Rule-based·✓ ReconstructableⓘFlags challenges when a sourced dimension falls below the published benchmark band: any leadership dimension < 58 (severe < 48), Stability < 50, Crisis Exposure > 60, or regime continuity/legitimacy < 40 — plus an adverse Stability Trend, adverse External Conditions, or Severely Constrained / Extreme domestic context. 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.
