What is notification fatigue?

Example: You want to build a daily reflection practice at the end of each workday. You could rely on your internal sense of 'it is time to wrap up' — but that trigger is diffuse, easily overridden by one more email, one more task. Instead, you create a recurring calendar event at 5:15 PM titled 'Daily Reflection — 3 questions' with a 5-minute alert. The calendar event fires at the same time regardless of your motivation, energy, or how absorbing the current task is. You pair it with a phone notification that links directly to your reflection template. Now the trigger is externalized, time-locked, and frictionless. After three weeks, you find the reflection fires on 90% of workdays — compared to the roughly 30% success rate when you relied on remembering. The digital trigger did not change your motivation. It changed the reliability of the activation signal.

This concept is part of Trigger Design in the How to Think curriculum.
