Group-Think is a new training programme and book by Danish artist Stine Marie Jacobsen that seeks to integrate ideas about collective intelligence and protest training methods into sports education in schools.

Group-Think shares first aid advice for protest and mass mobilisations, trains collaborative crowd skills, and promotes an awareness of the capacity to act in solidarity and collectively on behalf of global justice. The book introduces a series of open-source exercises that simulate crowd movements, fostering a training program to develop a new sense of collective sensitivity, group safety, and a revival of group swarm ideologies. The exercises are intended to be continuously developed by readers.

The exercises were co-written and tested by eighty Marseille school students from Collège Louis Armand, Collège Vieux Port and Lycée Périer; circus artists Sophie de Castelbajac, Pamela Pantoja and Andrew Graham from the National Circus Centre Archaos; and project advisor Jacques Soncin. The project is a commission by the European Nomadic Biennial Manifesta 13 in Marseille.
