Intrinsic vs Extrinsic Rewards for Long-Term Habits
Discover why external rewards often fail at building lasting habits, while internal motivation creates sustainable behavior change. Evidence-based guide.
You paid yourself $5 every time you went to the gym. It worked... for three weeks. Then it felt like a chore. The money stopped mattering. The habit died.
Or maybe you joined a program with prizes for hitting fitness goals. You crushed it during the challenge. The day after it ended, you stopped working out entirely.
This isn't failure. It's predictable psychology. External rewards—money, prizes, recognition—can jumpstart behavior. But they rarely create habits that last. For sustainable change, you need something different: internal motivation that comes from the behavior itself.
Understanding the difference between intrinsic and extrinsic rewards might be the most important habit lesson you'll learn. One creates temporary compliance. The other builds lasting identity.
What You'll Learn:
- Why external rewards often backfire for habit formation
- How intrinsic motivation creates self-sustaining behaviors
- Self-Determination Theory and the three psychological needs
- When external rewards actually help (and when they hurt)
- How to transition from external to internal motivation
The Two Types of Reward
Every behavior is driven by some form of reward. But not all rewards affect habits the same way. Both types of rewards are central to the science of rewards and habit motivation.
Extrinsic rewards come from outside: money, prizes, recognition, grades, approval, avoiding punishment. You do the behavior to get the reward, not because the behavior itself is satisfying.
Intrinsic rewards come from within: enjoyment, curiosity, personal meaning, mastery, autonomy, growth. You do the behavior because the act itself is inherently rewarding.
Research consistently shows that intrinsic motivation leads to:
- Greater persistence when challenges arise
- Higher quality performance
- More creativity and problem-solving
- Better long-term retention of the behavior
- Greater overall wellbeing
Extrinsic motivation creates:
- Faster initial adoption (when rewards are present)
- Performance only when monitored or rewarded
- Behavior that stops when rewards cease
- Focus on minimizing effort to get the reward
- Sometimes undermining of natural interest
This doesn't mean external rewards are always bad. But understanding when and how to use them is critical.
The Overjustification Effect
In the 1970s, psychologists Mark Lepper and David Greene conducted a now-famous experiment with preschool children who enjoyed drawing.
They divided kids into three groups:
- Expected reward: Told they'd get a "Good Player" certificate for drawing
- Unexpected reward: Received the certificate as a surprise after drawing
- No reward: Just drew for fun
Two weeks later, researchers observed the children during free play. The kids who expected a reward spent significantly less time drawing than the other groups. The expected external reward had killed their natural enjoyment.
This is called the "overjustification effect"—when you add external rewards to behavior people already find intrinsically rewarding, you undermine their internal motivation. The reward shifts their reason for doing the activity from "I enjoy this" to "I do this to get the reward."
Your brain essentially thinks: "If someone has to pay me to do this, it must not be worth doing for its own sake."
This has enormous implications for habit formation. If you try to build a habit using only external rewards, you create dependency on those rewards. Remove them, and motivation collapses. Motivation that depends on external factors is inherently fragile.
When External Rewards Backfire
External rewards are particularly problematic when:
1. The behavior is already enjoyable Adding payment to a hobby can make it feel like work. Many people report losing joy in their creative pursuits when they try to monetize them.
2. The behavior requires creativity External rewards focus attention on the reward rather than the process. This narrows thinking and reduces creative problem-solving—exactly what you need for complex tasks.
3. The reward is perceived as controlling When external rewards feel like manipulation or control, they trigger psychological reactance. People resist doing what they're being pressured to do, even if they'd otherwise enjoy it.
4. Long-term habit formation is the goal External rewards might create compliance temporarily, but they rarely build intrinsic motivation. Once rewards stop, so does the behavior.
5. The behavior requires deep engagement Tasks requiring flow states or deep concentration suffer when external rewards split attention between the activity and the anticipated reward.
Self-Determination Theory: The Three Core Needs
Psychologists Edward Deci and Richard Ryan developed Self-Determination Theory (SDT) to explain intrinsic motivation. Their research identified three fundamental psychological needs that, when satisfied, create intrinsic motivation:
1. Autonomy
The need to feel that you're choosing your behavior freely, not being controlled or coerced.
What undermines autonomy:
- Being told exactly what to do and when
- Surveillance and monitoring
- Deadlines imposed by others
- "Should" and "must" language
- Rewards that feel like manipulation
What supports autonomy:
- Choice in how to approach goals
- Self-selected timing and methods
- Internal commitment rather than external pressure
- Understanding the "why" behind behaviors
People maintain habits longer when they feel autonomy over their approach. Forced compliance creates resentment and rebellion.
2. Competence
The need to feel effective and capable, seeing yourself improve and master challenges. Research shows that the science of motivation isn't just about willpower—it's about finding the right motivational strategy.
What undermines competence:
- Tasks too difficult (leading to repeated failure)
- Tasks too easy (leading to boredom)
- Lack of feedback on progress
- Comparison to others' performance
- Focus only on final outcomes
What supports competence:
- Appropriate challenge level (slightly difficult but achievable)
- Clear progress feedback
- Celebration of incremental improvement
- Process-focused metrics
- Mastery-oriented goals
Feeling competent is a powerful intrinsic reward. Every rep, every day of consistency, every small improvement reinforces the behavior.
3. Relatedness
The need to feel connected to others, to belong to something meaningful beyond yourself.
What undermines relatedness:
- Pure competition and rankings
- Individual isolation
- Judgment and criticism
- Performance pressure in social contexts
- Forced interaction without genuine connection
What supports relatedness:
- Shared goals with others
- Collaborative challenges
- Genuine encouragement
- Belonging without performance requirements
- Contribution to something larger than yourself
This is why group habits often succeed where solo efforts fail. The social connection provides intrinsic reward that sustains motivation when individual willpower wavers.
When External Rewards Actually Help
Despite everything above, external rewards aren't always harmful. Used strategically, they can support habit formation:
As Initial Activation Energy
For behaviors with no initial intrinsic appeal (like going to the dentist or doing taxes), external rewards can get you started. Once you begin, you might discover intrinsic value you didn't expect.
Example: You bribe yourself to try a new exercise class. You discover you actually enjoy it. The external reward helped you overcome initial resistance, but intrinsic enjoyment now sustains the behavior.
To Bridge the Gratification Gap
Many beneficial behaviors have long delays before natural rewards appear. External rewards can maintain behavior during this gap.
Example: Exercise benefits appear in weeks or months. Small immediate rewards (post-workout smoothie, checking off your tracker) bridge the gap until natural rewards (feeling stronger, more energy) emerge.
When Competence Feedback Is Delayed
If you can't easily see progress, external markers can provide the competence feedback that creates intrinsic satisfaction.
Example: Learning a language involves invisible neural changes. External milestones (completed lessons, test scores) make progress visible until you experience the intrinsic reward of actual communication.
For Initially Boring But Important Tasks
Some tasks are objectively not enjoyable but necessary. External rewards can sustain compliance until the behavior becomes automatic enough that you stop thinking about enjoyment.
Example: Flossing isn't fun. But after months of consistency, not flossing feels wrong. The behavior becomes automatic. External rewards got you through the formation period.
The Key Principles for Using External Rewards Wisely
1. Use them temporarily, not permanently External rewards should be training wheels that eventually come off, not a permanent crutch.
2. Make them informational, not controlling Rewards that recognize competence ("you're making progress!") are less harmful than rewards that feel like bribes ("do this or else").
3. Pair them with intrinsic reward development Always work to find or create internal satisfaction in the behavior itself, even while using external rewards initially.
4. Don't use them for already enjoyable activities Never add external rewards to behaviors people already do for fun. This will kill natural motivation.
5. Remove them gradually Don't suddenly eliminate all external rewards. Fade them out as intrinsic motivation builds.
Transitioning from External to Internal Motivation
Data from Habitica users reveals how gamification affects intrinsic motivation.
The goal is to start behaviors with whatever motivation you can muster (sometimes external) and progressively shift toward intrinsic motivation. Here's how:
Step 1: Connect to Personal Values
Even if you start a behavior for external reasons, link it to what genuinely matters to you.
Instead of: "I need to exercise to lose weight for the wedding" (external) Try: "I want to exercise to feel capable and energized as I age" (internal value)
Step 2: Focus on Process, Not Just Outcomes
Shift attention from the end goal (external) to the experience of doing the behavior (internal).
Instead of: "I'm writing to finish this book" (outcome) Try: "I'm writing to explore these ideas and express myself" (process)
This is the core of identity-based habits—you're not just doing the behavior to get something, you're becoming someone who does this.
This is why identity-based habits are so powerful—they tap into who you want to become, not just what you want to achieve.
Step 3: Cultivate Intrinsic Interest
Actively look for aspects of the behavior you genuinely enjoy or find interesting.
For exercise: Maybe you hate running but enjoy the quiet morning time alone, or the feeling of your body moving, or the post-workout mood boost.
For healthy eating: Maybe you don't love vegetables but enjoy cooking, or the challenge of finding creative recipes, or feeling energized after meals.
Find something in the process itself that provides intrinsic reward.
Step 4: Increase Autonomy
As the behavior becomes more established, give yourself more choice in how you do it.
Initially: Follow a strict program (structure helps when motivation is low) Later: Modify the program to match your preferences Eventually: Create your own approach entirely
The more the behavior feels like your choice, the more intrinsically motivating it becomes.
Step 5: Celebrate Competence
Notice and acknowledge your growing capability. This is intrinsic reward—the satisfaction of becoming better at something. Self-compassion helps maintain intrinsic motivation even when progress is slow.
Don't just celebrate outcomes. Celebrate:
- Showing up consistently
- Improving technique
- Handling challenges better
- Maintaining commitment during difficult periods
Competence is one of the most powerful intrinsic motivators.
How Different Challenges Affect Intrinsic vs Extrinsic Motivation
Not all accountability structures support intrinsic motivation equally:
Prize-based challenges rely entirely on external rewards. They can create initial excitement but often fail to build lasting habits. Research shows prize-based motivation is less effective than intrinsic motivation for long-term behavior change.
Individual competitive challenges can undermine intrinsic motivation by making the behavior about beating others rather than personal growth. Comparison focus reduces autonomy and relatedness.
Cohort-based challenges can support intrinsic motivation when designed well. The key factors:
Autonomy support: You choose your own goals and approach
Competence recognition: Progress is visible and acknowledged
Relatedness satisfaction: You're connected to others without competition
The structure matters. Challenges that maintain autonomy, provide competence feedback, and create genuine connection support intrinsic motivation. Those that control, compare, and compete often undermine it.
The Sweet Spot: Autonomous External Motivation
SDT researchers identified a middle ground: "autonomous external motivation." This happens when you internalize external reasons and make them your own.
Example: You start exercising because your doctor said you should (external). Over time, you adopt health as a personal value. Now you exercise because you've decided it matters to you, not because someone else said so. It's still technically for external outcomes (health), but you've made it internally meaningful.
This is different from purely extrinsic motivation (doing it only to please the doctor) and from pure intrinsic motivation (exercising only because you enjoy the activity itself).
Many lasting habits operate in this zone: you do them partly for outcomes you've chosen to value (autonomous external motivation) and partly because you've come to identify with the behavior (intrinsic motivation).
The goal isn't always pure intrinsic motivation. The goal is avoiding controlled external motivation, where you feel pressured by outside forces rather than choosing based on your own values.
Key Takeaways
The type of reward matters as much as the reward itself:
-
External rewards work for initial adoption but rarely create lasting habits. Use them temporarily, not permanently.
-
Intrinsic motivation—based on autonomy, competence, and relatedness—creates self-sustaining behaviors. Focus on cultivating these psychological needs.
-
Adding external rewards to already enjoyable activities kills natural motivation. Don't reward what people already do for free.
-
The goal is transition: external to internal. Start with whatever gets you moving, but progressively shift toward intrinsic satisfaction.
-
Not all external motivation is bad. Autonomous external motivation (doing something for self-chosen outcomes) is stable and effective.
Next Steps:
- Audit your current habits: which are driven by external rewards, which by internal satisfaction?
- For one external-reward habit, identify potential sources of intrinsic motivation
- Increase autonomy in your habit approach
- Track your progress to build competence recognition

Frequently Asked Questions
Q: Can I ever stop needing external rewards for a habit?
A: Yes, but it requires deliberately cultivating intrinsic motivation. As you build autonomy, competence, and relatedness around the behavior, external rewards naturally matter less. Most habits that last 6+ months transition to at least some intrinsic motivation.
Q: What if I genuinely don't enjoy a necessary habit?
A: Not everything will be intrinsically enjoyable. Focus on: (1) connecting it to personally meaningful outcomes, (2) finding autonomy in how you do it, (3) appreciating your growing competence, (4) making it automatic enough that enjoyment doesn't matter. Some habits run on autonomous external motivation rather than pure intrinsic joy.
Q: Are habit tracking apps bad because they're external rewards?
A: Not necessarily. Trackers provide competence feedback (progress visibility), which supports intrinsic motivation. They become problematic when the streak or number becomes more important than the actual behavior. Use them to see progress, not as a reward system that controls you.
Q: How do I know if I've transitioned to intrinsic motivation?
A: Ask yourself: Would I continue this habit without any external outcome? If you'd stop exercising if it didn't affect your weight, that's still external. If you'd keep exercising because it makes you feel good and you identify as someone who takes care of their body, that's at least partially intrinsic.
Q: Can intrinsic motivation fade over time?
A: Yes, especially if autonomy, competence, or relatedness needs stop being met. This is why long-term habits need refreshing—new challenges, different approaches, reconnecting to why it matters. Maintaining intrinsic motivation is active work, not a one-time achievement. For people with ADHD, understanding how dopamine affects habit formation is crucial for designing effective reward systems.
