About this episode

Robert Cialdini discusses how changing two words on a menu led to an 18% increase in sales for a chain of Chinese restaurants.

16 years ago a chain of Chinese restaurants wanted to increase sales without changing the price. They didn’t change the product. The service. The chef. The food.

Today, Cialdini explains the social proof principle, sharing how changing just two words could increase your sales. --- Unlock the Nudge Vaults: https://www.nudgepodcast.com/vaults Read Cialdini’s bestseller Influence: https://amzn.to/4prHb7Y Read the new and expanded Influence: https://amzn.to/43TY0jI Read Pre-Suasion: https://amzn.to/48hA6Qr Read Yes!
