Today on Nudge, Toby Park from the Behavioural Insights Team explains how renaming a meat-free dish doubled its sales. Why targeting home-movers made Americans 400% more likely to cycle. How social norms can increase sales by 20%. And the reframing led the majority of Brits to choose energy-efficient fridges.
