Seshat / EMEWS

player
A giant database of 800 human societies over 10,000 years lets researchers test how civilizations really work.
Who they are

Seshat, a large historical databank, alongside EMEWS, a supercomputing modeling tool.

What they do

The engine treats it as the empirical bedrock — hard data — for studying how social complexity develops.

How it works

Seshat covers 800+ societies across 10,000 years and uses statistical analysis (PCA) to find shared pathways of rising complexity; EMEWS is a Department of Energy high-performance-computing platform for agent-based modeling.

Why it matters

It grounds the engine's big claims about history in a broad, testable evidence base rather than guesswork.

The engine's record — word for word
Empirical bedrock. 800+ societies, 10,000 years. PCA validation of universal complexity pathways. EMEWS: DOE HPC agent-based modeling.
