Question
Why does trigger stacking fail?
Quick Answer
Stacking so many conditions that the trigger never fires at all. You went from 'when I feel stressed' (fires 40 times a day) to 'when I feel stressed AND it is between 2-3pm AND I am at my desk AND my calendar is clear AND I have slept well' (fires zero times a week). Over-specificity kills.
The most common reason trigger stacking fails: Stacking so many conditions that the trigger never fires at all. You went from 'when I feel stressed' (fires 40 times a day) to 'when I feel stressed AND it is between 2-3pm AND I am at my desk AND my calendar is clear AND I have slept well' (fires zero times a week). Over-specificity kills activation just as surely as under-specificity kills precision. If your compound trigger has not fired in a week, remove the weakest condition.
The fix: Pick one behavior you want to activate more reliably. Write the single trigger you currently use (or would use). Now add a second qualifying condition using AND. Then add a third. Test the compound trigger for three days and track: How many times did it fire? How many of those were genuine opportunities to act? Compare the hit rate against what a single-condition trigger would have produced.
The underlying principle is straightforward: Combining multiple trigger conditions for higher-specificity activation.
