Why this matters

A crisis that censorship and regulation cannot fix.

India is among the countries most severely affected by organised disinformation. Fake news has fuelled hate crimes, spread health misinformation, and deepened social divisions. State regulation and platform-level censorship have not contained the problem.

The most durable solution is to strengthen citizens' capacity to reason for themselves. And the right place to build that capacity is school.

What we did

A curriculum pilot, tested with rigour.

Embedding critical thinking across every subject in every school would take decades. Teaching it as a standalone co-curricular subject addresses the urgent need now, while the larger reform takes shape.

India Institute designed and piloted a critical thinking curriculum for grades 8 and 9 in government and government-aided schools. The curriculum focuses on four skill clusters: reasoning through complex topics, evaluating information systematically, drawing sound inferences, and identifying weak arguments. Activities are built around stories, puzzles, and structured discussion, age-appropriate and designed to work in classrooms where reading and writing proficiency varies.
