Social norms theory is garnering increasing attention. What is it? And how might it strengthen interventions and research? To learn about and apply this approach, STRIVE gathered a group of partners and colleagues for three days, 28 to 30 January 2013, at a rather grand (but subsidised) lodge in Windsor Park, outside London. Find information and references on social norms theory from the meeting here. The photos show some of the participants and presenters and the venue.
