The Shocking Theory That Predicted Western Decline

In 1934, Oxford anthropologist J.D. Unwin published a controversial study examining 80+ tribes and multiple major civilizations across 5,000 years of history.

His conclusion?

No civilization survived the collapse of its sexual moral code.

In Sex and Culture, Unwin argued that strict norms around marriage, monogamy, and especially female sexual restraint were directly tied to civilizational expansion, innovation, and long-term stability.

When those norms weakened, societies gained freedom — but lost cohesion, ambition, and momentum within three generations.

Today, Western civilization faces:

• Declining birth rates
• Delayed marriage and rising divorce
• Political polarization and emotional discourse
• Institutional instability
• Cultural fragmentation

Are these disconnected trends — or part of a historical pattern?

Are we repeating history?
