What is habit triggers?

Habit triggers is a concept in personal epistemology: A trigger must be something you can detect consistently.

Example: You set a trigger: 'When I feel stressed, I'll do a breathing exercise.' Three weeks later, you've done it twice — not because you lack willpower, but because 'feeling stressed' is not something you detect reliably. You're often stressed without recognizing it until hours later. Now compare: 'When I close my laptop lid at the end of the workday, I'll do three slow breaths.' The laptop lid closes the same way every time. You never miss it. The trigger fires every single day.

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