What the Research Says

Habit formation is one of the most studied areas in behavioral psychology. Here's what the science tells us about how habits really form.

[TODO: Summarize key research on habit formation — cue-routine-reward loop, habit loop, etc.]

The Cue-Routine-Reward Loop

Charles Duhigg popularized the habit loop: cue, routine, reward. Understanding this loop is the first step to building better habits.

BJ Fogg's Behavior Model

How Long Does It Take to Form a Habit?

The common myth is 21 days. Research by Phillippa Lally shows it actually takes 18 to 254 days depending on the habit and the person.
