BJ Fogg founded the Behavior Design Lab at Stanford University, where he directs research and super hot trigger. In addition, he teaches industry innovators how to use his models and methods in Behavior Design. The purpose of his research and teaching is to to help millions of people improve their lives. Persuasive Technology: Using Computers to Change What We Think and Do.
Mobile Persuasion: 20 Perspectives on the Future of Behavior Change. The third element of the Fogg Behavior Model is Prompts. Without a Prompt, the target behavior will not happen. Sometimes a Prompt can be external, like an alarm sounding.
Other times, the Prompt can come from our daily routine: Walking through the kitchen may trigger us to open the fridge. The concept of Prompt has different names: cue, trigger, call to action, request, and so on. I once called this element the «Trigger. I changed this term in late 2018. Facebook uses Prompts effectively to achieve their target behaviors. Facebook account in a while, so Facebook automatically sent me this Prompt to achieve their target behavior: Sign into Facebook. I’ve posted a screenshot of the email below.
Note how this specific behavior — signing in — is the first step of Facebook’s larger goal: reinvolve me in Facebook. What the system doesn’t know is that I’m already super involved using Facebook with my real account. My demo account is for teaching only. My Behavior Model names three types of Prompts: Facilitator, Signal, and Spark. Those designing to influence behavior should use the Prompt type that matches their target user’s context, which combines Motivation and Ability.
Look at the Facebook example above. As I see it, this message from Facebook is mostly a Facilitator. In addition to the green button, the Prompt message provides three other links that take me to Facebook. An effective Prompt for a small behavior can lead people to perform harder behaviors. For example, if I can prompt someone to walk for 10 minutes a day, that person may then buy some walking shoes without any external triggering or intervention.
