Methodology

Why the Democratic Quality Index uses a geometric mean

DQI = (V-Dem × Freedom House × RSF)^(1/3). A geometric mean is used so that a collapse in any single dimension drags the whole index down — a country with strong elections but no press freedom is correctly penalised. Arithmetic means would obscure this.

Democratic quality is multiplicative, not additive — one weak pillar undermines the rest.
