What is habit review?

Example: You set a trigger six months ago: 'When I open my laptop in the morning, I review my task list before checking email.' It worked beautifully for three months. Then you switched to a standing desk, started your mornings with a team standup, and the laptop-opening moment disappeared. The trigger is still technically in your system. It fires zero times per week. You don't notice because you never audit — you just feel a vague sense that your mornings lost their structure.

This concept is part of Trigger Design in the How to Think curriculum, which builds the epistemic infrastructure for trigger design.
