Rough AI truth score

67/100

Morris offers an explicit, testable macrohistory rather than a cultural superiority story. Geography plainly constrains development, but his East/West units, composite index, and projection to 2100 are far less certain than the narrative suggests.

Based on three central claims · medium confidence

The three claims

01Mostly supported

Biology and basic social behavior are shared, while geography chiefly explains why western societies gained global dominance when they did.

Rejecting innate civilizational superiority is well grounded, and access, ecology, energy, and changing transport costs matter greatly. Institutions, contingency, empire, state competition, and culture also interact with geography and resist ranking as secondary everywhere.

02Mixed

A single social-development index can meaningfully compare East and West over roughly fifteen thousand years.

Energy capture, urbanism, information processing, and military capacity are relevant and Morris discloses his method. Sparse ancient estimates, changing meanings, aggregation weights, and broad regional boundaries produce substantial false precision.

Other claims worth checking
  • Social development repeatedly hits ceilings that force institutional change.
  • Nuclear war and climate disruption could make East-versus-West forecasts irrelevant.

What this number means. It is an AI-generated first-pass judgment of three central factual or causal claims—not a rating, exhaustive fact-check, or human peer review. Claim credits are 100% for supported, 75% for mostly supported, 50% for mixed, and 25% for weak, then averaged and rounded. Lower confidence means the score should move more as better evidence arrives.
