Question
Why does pre-commitment strategy fail?
Quick Answer
Writing pre-commitment rules that are too vague to enforce. 'I'll eat healthier' is a goal, not a pre-commitment. 'If I reach for a snack after 8pm, then I drink a glass of water and wait ten minutes' is a pre-commitment. The other failure mode is creating so many rules that you can't track them..
The most common reason pre-commitment strategy fails: Writing pre-commitment rules that are too vague to enforce. 'I'll eat healthier' is a goal, not a pre-commitment. 'If I reach for a snack after 8pm, then I drink a glass of water and wait ten minutes' is a pre-commitment. The other failure mode is creating so many rules that you can't track them. Start with one. Make it stick. Then add another.
The fix: Identify one decision you repeatedly make poorly under pressure — snacking, doom-scrolling, saying yes to meetings that should be emails. Write a pre-commitment rule in if-then format: 'If [trigger], then [pre-decided action].' Make it concrete enough that you'll know whether you followed it. Put it where you'll see it before the trigger fires. Run it for five days and log compliance.
The underlying principle is straightforward: Deciding in advance what you will do in a specific situation removes in-the-moment temptation.
