The Power of Habit, and the loop that runs on a person
Read the habit loop first. Then read where it stops, and try the move at the end.
The book explains the habit loop well. A pattern is a loop whose starting signal is often another person.
THE BOOK
The Power of Habit, Charles Duhigg, 2012.
This page reads the book's main idea in our own words. It quotes no text from the book and speaks for no one who wrote it.
This book explains how habits really run. It uses stories about people, companies and sports teams to show the same loop again and again.
This page states its big idea fairly, says what it gets right, and names one gap. It quotes nothing from the book.
The big idea, stated fairly
Every habit has three parts. A cue, which is the signal that starts it. A routine, which is what you do. A reward, which is what you get.
The main rule: keep the cue and the reward, and change the routine in the middle. It also shows how one key habit can shift many others.
What it gets right
It is right that habits run on a loop, and that the loop can be mapped. It is right that you rarely delete a habit. You swap what happens in the middle.
Readers often say it explains the why better than the how. That is fair, and the why still helps.
The gap it leaves
Most of the book's cues are times and places: the afternoon slump, the walk past the kitchen. Those can be planned for.
A pattern's cue is often a person. A partner goes quiet, or a boss frowns. It fires fast, and the routine runs before you see the loop.
Changing the routine is the right idea. The hard part is noticing the cue in time to do it.
Where Behavioral Interception fits
Behavioral Interception is the practice of catching an automatic pattern as it begins, intercepting its usual response, and practicing a different action until it becomes more natural.
It puts the book's swap into the seconds. First you feel the body signal, a stomach drop or tight chest, and name the pattern.
Then you run the different action in place of the old one. Repeat it each time the signal comes back.
The free Crash Course, short lessons on your pattern, starts by naming it.
