This method treats habits as brain wiring, not decisions, and works with that reality instead of against it. Because neural pathways don't fully erase once formed — a craving can resurface even after a decade, as in the show's horse-riding smoking story — the mechanism isn't to try to delete the habit through willpower, but to disrupt the physical or environmental cue that automatically triggers it. Concretely: if a phone is habitually pulled from one pocket, moving it to the other pocket, or rearranging app icons on the home screen, breaks the automatic cue-response link and forces a moment of conscious choice instead of reflexive action. Every repetition of a behavior — good or bad — makes that behavior more likely tomorrow, so the same mechanism used to interrupt bad habits can be used deliberately to build good ones.
Origin
Chris Williamson synthesizes this from a Jordan Peterson line — 'don't practice what you do not want to become' — and his own experiments, in the show's 400th-episode lessons special (2021), illustrated with a story about a woman whose teenage smoking habit resurfaced on a horse ride over a decade later.
Core principles
- 01Habits are cue-triggered neural pathways that don't erase once formed — they only go dormant.
- 02You can't delete a habit loop, but you can break the environmental cue that triggers it.
- 03Every action taken today is a vote for how likely you are to repeat it tomorrow.
- 04Small physical changes to environment interrupt automatic behavior more reliably than willpower alone.
How to run it
- 1
Identify the habit and its physical cue
Name the exact unwanted habit and the specific physical or environmental trigger that sets it off — a location, an object, a hand used, a time of day.
Pro tip Watch yourself do the habit once, in real time, and note the exact sequence of cue then action.
- 2
Choose one concrete change to the cue
Pick a single physical alteration — move the object, switch hands, reposition an icon — that will no longer match the automatic motion.
Watch out Keep the change concrete and physical; a purely mental intention to 'try harder' won't disrupt the cue.
- 3
Apply the change consistently
Make sure the new arrangement is in place every time, so the old automatic motion reliably lands somewhere unexpected.
Pro tip Consistency matters more than intensity — a small change applied every time beats a big change applied occasionally.
- 4
Notice the friction as the interrupt working
When you catch yourself confused or hesitating mid-motion, that moment of friction is the pattern interrupt succeeding, not a sign to give up.
- 5
Track relapses without judgment
Expect the old wiring to resurface, especially under stress, even long after the habit seemed gone. Log it and reapply the interrupt rather than treating it as failure.
Pro tip Stress and fatigue are the most common relapse triggers — plan for those moments specifically.
Watch out Old neural pathways can reactivate years later; a relapse doesn't undo prior progress.
- 6
Apply the same technique to the next habit
Once the new pattern feels automatic, use the same cue-disruption approach on the next habit you want to change.
In the wild
Chris describes swapping which pocket holds the phone versus the wallet, so the reflexive hand-to-pocket motion no longer lands on the phone automatically.
→ The automatic reach-and-check habit breaks because the object isn't where the hand expects it, forcing a conscious moment before checking the phone.
Moving a banking app to the exact spot a social media app used to occupy means the automatic thumb-tap now opens the wrong thing.
→ The mismatch interrupts the cue-craving-reward loop embedded in muscle memory and forces a deliberate look at the screen.
Common mistakes
Relying on willpower instead of changing the cue
Trying to simply resist the habit through determination leaves the underlying trigger intact, so the craving reappears the next time the cue occurs.
Expecting the craving to disappear permanently
Neural pathways go dormant rather than erase, so treating a relapse years later as total failure misunderstands how habits actually work.
Making a cosmetic change that doesn't alter the trigger
A change that doesn't actually intersect with the automatic motion — such as a vague intention rather than a physical rearrangement — fails to interrupt the cue-response chain.
Is it for you?
Best for
Someone trying to break an automatic low-value habit, such as reflexive phone checking, where the trigger is a physical or environmental cue.
Not ideal for
Deep clinical addictions requiring medical intervention — pattern interrupts reduce friction but don't replace treatment for serious dependency.

“don't practice what you do not want to become”
“every action you take is a vote for the kind of person you're going to be in the future”
“if you swap it around it's going to pattern interrupt that natural thing that you've got in your mind where you just put your hand…”
