Even if you study neuroscience and understand the principles of habit formation, you still find yourself feeling helpless in front of a delivery app on your way home from work. This is because knowledge stays in the prefrontal cortex, while temptation erupts from the basal ganglia. In particular, stressed office workers in their 30s experience "effort-cost inflation," a phenomenon where the brain perceives the cost of making healthy choices as higher than it actually is. It is not that you lack willpower; it means your brain is in a state of malfunction.
When an impulse surges, use the RAID technique proposed by Michelle McDonald. This is a training exercise in channeling an objective observer rather than mere abstract curiosity.
Going through this process reduces amygdala activation. In fact, this brief pause alone can save you over 200,000 KRW a month in unnecessary delivery expenses.
Observing alone is difficult. Use numbers. Rate the contraction of your stomach when you aren't actually hungry, or the movement of your fingers toward your smartphone, on a scale of 1 to 10. The moment you convert interoceptive sensations into clear numbers, cravings become controllable data. The 60-second recording time forces the brain to re-evaluate fake rewards.
By the time an office worker in their 30s leaves work, their willpower is already depleted. At this point, physical barriers are far more powerful than mindset. Utilize what behavioral economics calls "positive friction." It is the same principle as when Google’s cafeteria saw a sharp drop in snack consumption simply by placing treats in opaque boxes on high shelves.
Just reading this question before turning on the screen can reduce mindless scrolling by 1.5 hours a day. Adding a grayscale mode setting blocks visual dopamine rewards, making it much easier to put the phone down.
The shame felt when breaking a habit releases cortisol. To relieve this stress, the brain falls into the "what-the-hell effect," seeking rewards again. Self-blame is the worst choice, as it causes failure to repeat. Instead, create a failure database.
Immediately after a failure, write down the following three things:
Criticizing yourself by saying "I have weak willpower" is of no help. Realizing that "I succumb to temptation when I sleep less than 5 hours" is the only way to prevent the next failure.
The reason the brain repeats bad habits is that it overestimates the pleasure those actions provide. Neurologically, you must disappoint the brain by utilizing Reward Prediction Error ().
Write a weekly reward satisfaction report. Compare your expectations before the action with your actual satisfaction after the action on a 10-point scale. You will find that after eating, your mouth feels dry, your stomach feels bloated, and your chest feels tight with guilt. Record this discomfort in specific language. Once the brain's learning algorithm is updated to "this action has low value," you will naturally drift away from that habit without even trying.
