The Slow Decay of Democracy

Democracies rarely die in a coup anymore — they erode, one institution at a time. Can that erosion be detected in data? We calibrate a detector on three documented cases, check it stays quiet on a healthy control, then point it at India — and reach a verdict.

■ VERDICT — HYPOTHESIS SUPPORTED

Yes. India shows the same decay signature as documented backsliders.

The detector — calibrated on Hungary, Turkey and Venezuela, quiet on Switzerland — fires for India: a fall of −0.33 in the liberal-democracy index from its 1998 peak, sustained for 17 years, onset ≈ 2013, in the classic order (press first, courts last). Details, method and caveats below.

01What slow decay looks like

V-Dem's liberal democracy index (0–1) scores free elections plus the liberal guardrails — press freedom, civil liberties, courts that bind the executive. Three countries with well-documented backsliding, one healthy control, and India:

02A decay detector

Slow decay has a measurable shape. Borrowing thresholds from V-Dem's “Episodes of Regime Transformation” research, a country is in a decay episode when:

DETECTOR — fires when, from the country's post-1990 peak of the liberal-democracy index:
① total decline ≥ 0.10  ·  ② the index stays below peak − 0.05 for ≥ 5 consecutive years.
Onset = start of the steepest 10-year fall. Calibration: must fire on Hungary, Turkey, Venezuela; must stay quiet on Switzerland.

Calibration passes: all three known backsliders fire, the control does not. Only then is the detector allowed to look at India.

03The playbook: what falls first

Decay is sequenced, not simultaneous. For each country, the year each institution first fell ≥ 0.05 below its pre-onset peak, relative to the country's onset year:

Read a row left→right: dots near 0 fell with the onset; dots to the right held out longer. Hover any dot for the exact year and how far that institution has fallen since.

04India under the lens

India's six V-Dem indices since 1990. The dashed line marks the detected onset (2013). Expression and media fall first and hardest; judicial constraints hold out longest — the same order as Hungary and Turkey:

05Same clock, same curve

Align every country at its own onset year (year 0) and the trajectories become directly comparable. India's first 12 years of decline track Hungary's almost point-for-point:

06The verdict, in full

■ THE SENTENCE UNDER TEST

“India shows the signs of slow democratic decay seen in countries with a documented history of it.”

Verdict: correct — the sentence makes sense and is supported by the data.

Honest caveats — what the verdict does not say:

07Method & data

Data: V-Dem v15 (2025) via Our World in Data — six indices (liberal democracy, electoral democracy, freedom of expression, judicial constraints on the executive, civil liberties, freedom of association), 1975–2025, best point estimates. The full pipeline (raw CSVs + analyze.py) is in the repo; every number on this page is reproducible from it.
