What is event-based triggers for behavior change?

Event-based triggers for behavior change is a concept in personal epistemology: Linking an agent to a specific event like arriving at work or opening your laptop.

Example: You want to review your daily priorities before getting pulled into reactive work. You have tried setting a reminder for 9:00 a.m., but some days you arrive at 8:45 and some days at 9:15 — the alarm fires at the wrong moment either way. So you switch to an event-based trigger: 'When I sit down at my desk and open my laptop, I review my three priorities before opening email.' The trigger is no longer a time. It is an event — the physical act of opening your laptop. It fires at the right moment regardless of what time you arrive, because the event itself is the signal. Within a week, the laptop lid opening and the priority review become a single behavioral unit. You stop needing to remember. The event remembers for you.

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