A national border for information

From East Asia·A current case, last reviewed September 2026

China's filtering infrastructure produces an internet where searches, encyclopedias and archives return different results than elsewhere, and a generation has grown up inside a distinct information ecosystem with its own platforms and silences. The thought experiment of communities knowing different worlds now has infrastructure.

The concepts this raises

Each of these gives a class a different way into the same case.

PowerKnowledge and Society
The capacity to shape what counts as knowledge, who is heard, and what gets funded, published or taught. Power is not only censorship; setting an agenda, controlling a platform or being granted authority all change the knowledge that a community ends up with.

Where it sits in the knowledge framework

Ethics
The ethical questions internal to the knowledge itself: what may be investigated and how, what obligations the knowledge places on those who hold it, and the ethical constraints the discipline imposes on its own practitioners.

Areas of knowledge

Themes

The same ideas, somewhere else

Cases that raise a concept this one raises, but in a different area of knowledge or a different part of the world. That contrast is the point: it is what shows a student the concept travels.
