Clear turns the four-stage habit loop into four actionable laws, one per stage. To build a good habit: make it obvious (cue), make it attractive (craving), make it easy (response), and make it satisfying (reward). Each law has many tactics beneath it, so the framework is a toolkit rather than a single rule — you pick the wrench, hammer, or screwdriver your situation needs. To break a bad habit, you invert each law: make it invisible, make it unattractive, make it difficult, and make it unsatisfying. Clear notes the 'make it unattractive' inversion is the trickiest and suggests leaning on the other three.
Origin
Clear created the four laws to operationalize the cue-craving-response-reward science into something people could actually use in daily life, reflecting his self-described role as a bridge between academic research and practical application.
Core principles
- 01Each law operationalizes one stage of the habit loop into an action you can take.
- 02To build a habit: make it obvious, make it attractive, make it easy, make it satisfying.
- 03To break a habit: invert each law — make it invisible, unattractive, difficult, unsatisfying.
- 04There is no single way to build a habit; the four laws are a toolkit to choose from.
How to run it
- 1
Make it obvious
Design the cues of your good habits to be visible and easy to see; the easier a cue is to notice, the more likely you act on it.
Pro tip Habit stacking and environment design both work by making the cue obvious.
- 2
Make it attractive
Increase the appeal of the habit so it feels more enticing and motivating.
Watch out When breaking habits, the inverse ('make it unattractive') is the hardest law — don't rely on it alone.
- 3
Make it easy
Reduce friction and remove steps so the behavior is convenient and simple to perform.
Pro tip Even a tiny amount of added friction can reliably suppress an unwanted habit.
- 4
Make it satisfying
Attach an immediate rewarding or pleasurable payoff so the brain wants to repeat it.
- 5
Invert to break bad habits
Flip each law: make the cue invisible, the behavior unattractive, the action difficult, and the outcome unsatisfying.
Pro tip Unsubscribe from tempting emails and keep junk food out of the house to make bad cues invisible.
In the wild
To break compulsive phone-checking, Clear applies 'make it difficult': he leaves his phone in another room until lunch. Though his home office is only 30 seconds from the phone, he never walks to get it — the small friction is enough.
→ He curbs the habit roughly seven days out of ten despite the phone being just down the hallway.
Chips right next to you are far easier to eat than chips three miles away at the store. Adding steps between you and the behavior lowers the odds it occurs — an application of 'make it difficult'.
→ Increasing friction reduces the unwanted behavior to the desired degree.
Common mistakes
Relying on 'make it unattractive' to break habits
Clear calls this the trickiest, hardest inversion; focusing on making a bad habit invisible, difficult, or unsatisfying is usually more effective.
Expecting one law to do all the work
The laws are a toolkit — treating any single one as the whole solution ignores that different situations call for different levers.
Is it for you?
Best for
Individuals and teams who want a diagnostic checklist to increase the odds a target behavior occurs.
Not ideal for
Someone wanting a single prescriptive rule rather than a menu of strategies to adapt to their situation.
From the transcript
“the first law is to make it obvious... the second law is to make it attractive... the third law is to make it easy... and…”
“if you want to break a bad habit then you just invert those four so rather than making it obvious make it invisible”
