How to Kick Bad Habits (and Start Good Ones)
Dr. Laurie Santos and guest Wendy Wood explore how to break bad habits and form good ones by understanding habit formation, context, and friction. They draw lessons from Vietnam vets' heroin addiction to illustrate the power of environmental cues.

6 Key Concepts
Habit Formation
Habits are behaviors we repeat until they become mental shortcuts, allowing us to achieve rewards efficiently and automatically. They involve three critical parts: a reward, a routine, and a context.
Willpower Fallacy
The mistaken belief that changing behavior primarily requires willpower and hard work. Willpower is often self-defeating because exerting it means constantly thinking about the undesired behavior, giving it energy to re-emerge.
Reward (Habit Component)
The desired outcome or positive feeling that a behavior provides, reinforcing its repetition. This can be anything from the taste of coffee to endorphins from exercise or reduced boredom from checking a phone.
Routine (Habit Component)
The specific sequence of actions that leads to a reward. The brain 'chunks' these individual actions into a single, perfectly stored routine, allowing for automatic execution without conscious thought, relying on the sensory motor system.
Context (Habit Component)
Any part of our situation or environment that cues or triggers a habitual behavior. This can include locations, times of day, preceding events, people, or even moods, and it strongly influences when our habit routines get activated.
Friction (Behavior Change)
Forces in our environment that make some actions more difficult and other actions easier. Increasing friction for bad habits (e.g., making them harder to access) or decreasing friction for good habits (e.g., making them easier to start) can significantly influence behavior.
6 Questions Answered
Willpower doesn't work well because when you exert it, you're constantly thinking about the behavior you want to avoid, which paradoxically gives it energy and makes it more likely to re-emerge. Instead, working smarter by changing your environment is more effective.
Habits form when behaviors are repeated and lead to a reward, becoming mental shortcuts. They consist of three critical parts: a reward (what feels good), a routine (the sequence of actions), and a context (environmental cues that trigger the routine).
Chunking is when the brain stores an entire sequence of behaviors for a routine as a single, solitary memory. This allows the unconscious parts of the brain to execute complex actions automatically without needing the conscious frontal lobes to remember each individual step.
The vast majority of Vietnam veterans were able to kick their heroin habit because their entire habit chain was disrupted by a change in context. The cues (boredom, stress, drug-taking buddies, easy access to cheap heroin, being in Vietnam) that prompted their drug use were gone in their home environment.
We can 'hack' our environment by making small changes that provide cues for desired behaviors and introduce 'friction' to make undesired behaviors more difficult. This leverages the power of context to shift our autopilot behaviors towards our goals.
Yes, proximity significantly affects eating habits. A study showed people ate a third fewer calories when healthy options (apple slices) were directly in front of them and unhealthy options (popcorn) were at arm's reach, compared to when the positions were reversed.
12 Actionable Insights
1. Avoid Relying on Willpower
Do not rely on willpower to change behavior because it is self-defeating; thinking about what you don’t want to do gives it energy to re-emerge.
2. Design Your Environment for Habits
Set up situations around you to make it easy to repeat desired behaviors, allowing them to become automatic without relying on willpower.
3. Apply Friction to Habits
Consciously increase friction to make bad habits harder to perform, and reduce friction to make good habits easier to adopt.
4. Consciously Control Your Context
Use your conscious mind to control the context you are in, as changing your environment can shift bad behaviors to desired ones.
5. Modify Environment for Good Cues
Make small, scientifically-backed changes in your environment (e.g., at home or work) to provide cues that promote desired behaviors.
6. Leverage Proximity for Behavior
Place desired items (e.g., healthy food) closer and less desired items further away, as proximity significantly influences automatic behavior.
7. Plan to Avoid Temptation Cues
Plan your shopping trips or other activities to actively avoid environments or aisles that trigger undesirable behaviors (e.g., the candy aisle).
8. Reduce Morning Routine Friction
To make early morning exercise easier, reduce friction by preparing the night before, such as sleeping in your running clothes.
9. Delete Distracting Apps
Delete social media or other distracting apps from your phone to increase friction and prevent compulsive checking.
10. Prominently Place Habit Apps
Download apps for desired habits (e.g., gratitude) and place them front and center on your phone to make them easily accessible and visible.
11. Use Screensaver as Behavior Cue
Set a photo of someone you want to call more often as your screensaver to serve as a visual cue for that desired behavior.
12. Display Important Lists Visibly
Place important lists, like a ’time windfall list,’ somewhere easily visible to serve as a constant reminder and cue for desired actions.
4 Key Quotes
When you exert willpower and control your behavior, what you're doing is you are thinking about the thing that you don't want to do. And in doing so, you give it energy to keep re-emerging.
Wendy Wood
When our brains see a cue that's been associated with a habitual behavior, we can't help but execute that behavior, even when the behavior is no longer rewarding.
Dr. Laurie Santos
The idea that nearly half of our waking day is on autopilot, that we're constantly governed by cues and context, is pretty shocking.
Dr. Laurie Santos
People who had habits to eat popcorn in the movie cinema ate just about the same amount of stale popcorn as fresh. They could tell us when we asked them that they hated the stale popcorn. They ate it anyway.

Wendy Wood's Frictionless Morning Exercise Routine
Wendy Wood- Decide to exercise early in the morning (e.g., 6 a.m.) to avoid conflicts with childcare.
- Choose an exercise with minimal friction, such as running.
- Reduce friction further by sleeping in running clothes to eliminate the step of getting dressed.
