Each law of behavior change is tied to one stage of Habit Feedback Loop, telling us how to optimize this part of the habit cycle to reduce the friction and increase the likelihood that a habit will be formed. Following through with all four laws is critical, as a failure at any stage breaks the habit loop. The four stages and their corresponding laws are:
Cue- Make it obvious - First law of behavior change
Craving- Make it attractive - Second law of behavior change
Response- 01 Inbox/Make it easy - Third law of behavior change
Reward- Make it satisfying - Fourth law of behavior change
Each law also has its inverse law, which can be applied to introduce friction into the four stages of undesired habits, helping us break them.
