A longitudinal, open-source index mapping how national leaders communicate. Built on the most comprehensive open corpus of global political speech, powered by the Global Institute for National Capability.
Every sentence in the corpus is tagged along six independent dimensions — Time orientation, Capability posture, Agency, Reference, Expression and Stance — so the structural texture of a speech can be compared across leaders, countries and moments. Pick a dimension to see how its share has moved across the corpus and how each option holds its share year on year.
