The term 'gently pushes' can be summarized as 'NUDGES' in six letters. Nudging is a concept that was developed by behavioral economists Richard Thaler and Cass Sunstein in their 2008 book, 'Nudge: Improving Decisions About Health, Wealth, and Happiness'. It is a way of influencing people's behavior in a positive way without forcing them to do something. Nudging involves providing subtle cues or incentives to encourage people to make decisions that are in their best interest. This can be done through small changes in the environment, such as changing the layout of a store or providing information about healthy eating.
