Triggers tell people to “do it now!”
The third element of the Fogg Behavior Model is Triggers. Without a Trigger, the target behavior will not happen. Sometimes a Trigger can be external, like an alarm sounding. Other times, the Trigger can come from our daily routine: Walking through the kitchen may trigger us to open the fridge.
The concept of Trigger has different names: cue, prompt, call to action, request, and so on.
