Humans naturally gravitate toward the option requiring the least work; design habits to be the path of least resistance.
From Atomic Habits by James Clear
From George Zipf's research, this principle explains why we default to convenient options. It's not laziness—it's efficiency. Clear's application: instead of fighting this tendency, work with it by reducing friction for good habits (prep gym bag the night before) and adding friction for bad habits (unplug TV after each use). Small amounts of friction have outsized effects on behavior.
Adding just 20 seconds of effort (the time to plug in a TV or re-enter a password) can be enough to break an automatic behavior loop. Conversely, reducing 20 seconds (laying out workout clothes) can make a good habit much more likely.
The Principle of Least Effort means people are lazy, when it actually reflects efficient cognitive resource allocation—our brains conserve energy for important decisions.
A framework for building habits: make it obvious (cue), attractive (craving), easy (response), and satisfying (reward).
FrameworkLasting behavior change comes from shifting your identity (who you are) rather than focusing on outcomes (what you achieve).
Mental ModelProgress accumulates invisibly beneath the surface before suddenly becoming visible, like ice melting at 32 degrees.
Mental ModelA specific plan that states when, where, and how you will execute a behavior: 'I will [behavior] at [time] in [location].'
TechniqueAnchoring a new habit to an existing habit using the formula: 'After I [current habit], I will [new habit].'
TechniqueScale down any habit to a two-minute version to overcome starting friction: 'Exercise for 30 minutes' becomes 'Put on workout clothes.'
TechniqueBehavior is shaped by environment more than willpower; design spaces to make good habits obvious and bad habits invisible.
PrincipleFocus on the process (systems) that leads to results rather than the results themselves (goals) for sustainable progress.
PrincipleJudging the frequency or probability of events by how easily examples come to mind, leading to overestimation of vivid, recent, or emotional events.

Judging probability by similarity to stereotypes or prototypes, while ignoring base rates and sample size.

When faced with a difficult question, System 1 automatically substitutes an easier question without conscious awareness of the switch.
