A concept based on the "Nudge Theory" in behavioral economics. Since human willpower is a depleting resource (ego depletion), this design method alters the physical environment to make good choices natural and bad choices difficult, without relying on willpower.
How to Do It
Create mechanisms that make rule-breaking physically impossible or tedious (e.g., instant logout after hitting loss limit, leaving phone in another room).
Effect
Even when emotional impulses peak, environmental constraints create a cooling-off period, preventing fatal mistakes.
How to Use
1. Formalize the daily loss limit rule
2. Decide a physical action to execute immediately upon triggering (e.g., turning off power)
3. Turn off trading app notifications
