Project Cybersyn

A Chilean project of 1971–1973 combining communications, modelling and management tools for nationalised industry. Its telex network saw operational use, but the coup ended the wider project before a full assessment of its ambitions.

What this check doesn’t establish

A participant retrospective and a historian’s excerpt do not establish the project’s full economic effect.
Specific assertions about every participant’s fate, the quality of all data and the complete historical debate were removed rather than presented as settled.

Confidence applies to the scope above, not every claim made by the underlying source. How confidence works

Cybersyn combined a telex network, statistical monitoring, an economic simulator and an operations-room project. Its communications network was used during the 1972 transport strike.

The September 1973 coup ended the project. Operational use of one component is different from successful testing of the whole proposed management system. This record therefore avoids both the claim that nothing was tested and the claim that its overall effectiveness was demonstrated.
