What is trigger maintenance?

Trigger maintenance is a concept in personal epistemology: Regularly review your triggers to ensure they are still relevant and well-calibrated.

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 Phase 22 (Trigger Design) in the How to Think curriculum, which builds the epistemic infrastructure for trigger design.
