Habit Loop
The habit loop is the three-part circuit behind every habit: a cue that triggers it, a routine that carries it out, and a reward that teaches the brain to run it again.
Charles Duhigg made the habit loop the organising idea of The Power of Habit, drawing on the MIT research that watched rats learn a maze until the behaviour ran without conscious effort. The point of the loop is not that habits are automatic, which everyone knows, but that they are structured: a cue, a routine, a reward, every time. Most attempts to change a habit fail because they try to suppress the routine while the cue and the reward stay in place, so the brain keeps looking for the reward and finds its way back to the old routine. What people get wrong is treating a habit as a decision they keep making badly. It is a circuit that fires on its own, and a circuit you can see is one you can rebuild.
A real-life example
Most nights at half past nine, once the children are asleep, Oğuz opens the fridge and eats standing up. For a week he writes down what happens just before: not hunger, but the house going quiet. The cue is the end of the day's duties; the reward is a marker that the day is over. He keeps both and swaps the routine: a cup of linden tea on the balcony for ten minutes. Within a fortnight the fridge visits have stopped.
How to use it
- 1Catch one habit today, good or bad, and write its three parts on one line: cue, routine, reward.
- 2Change only the routine. Keep the cue and give yourself the same reward through a different action.
- 3Test the reward by asking what you actually wanted afterwards; if the craving persists, you have named the wrong reward.
