What if the raise you’ve been chasing is actually making you worse at your job? In 1973, psychologists Mark Lepper, David Greene, and Richard Nisbett ran a now-famous study at Stanford: they gave children who already loved drawing a reward for drawing. Afterward, the kids who’d been rewarded drew significantly less — and with less creativity — than those who received nothing. The reward didn’t amplify motivation. It replaced it.
That finding launched decades of research into intrinsic vs extrinsic motivation, and the conclusions are more nuanced than most people realize. Understanding the difference isn’t just an academic exercise. It shapes how you lead, how you hire, how you build habits, and ultimately, how much of your potential you actually unlock.
1. The Core Distinction: What Each Type Actually Is
Intrinsic motivation is doing something because the activity itself is rewarding. You’re solving a problem because it’s interesting, building something because the craft matters, learning because you’re genuinely curious. The reward is baked into the action.
Extrinsic motivation is doing something to get a separate outcome: a salary, a promotion, praise, a grade, or to avoid a penalty. The activity is a vehicle. The goal is the destination.
Neither is inherently good or bad. The research gets interesting when you examine how they interact, especially when extrinsic rewards are layered on top of something someone already cares about.
Self-determination theory, developed by Edward Deci and Richard Ryan at the University of Rochester starting in the 1970s, frames motivation along a spectrum. At one end: pure external pressure. At the other: full internalization, where even “external” goals become genuinely your own because they align with your values. Most motivated behavior lives somewhere in between.
Practical takeaway: Before trying to motivate yourself or someone else, ask which type of motivation is operating. Diagnosing this correctly changes everything about your approach.
2. The Overjustification Effect: When Rewards Backfire
The Stanford drawing study introduced a concept now called the overjustification effect: when you introduce external rewards for an intrinsically motivated activity, you can undermine the original motivation. The person shifts from “I’m doing this because I love it” to “I’m doing this for the reward.” Remove the reward, and engagement collapses.
This plays out in organizations constantly. In 2009, Dan Pink’s book Drive popularized what management researchers had been documenting for years: piece-rate pay systems and performance bonuses routinely fail to improve — and sometimes actively hurt — performance on complex, creative, or cognitively demanding tasks.
Atlassian, the software company behind Jira and Confluence, took this seriously under CEO Scott Farquhar. They introduced “ShipIt Days” (later called “Innovation Week”), 24-hour hackathons where engineers could build anything they wanted, with zero requirement to make it commercially viable. No bonuses tied to outcomes. No performance reviews attached. The intrinsic pull of curiosity and creative ownership was the entire point. Some of Atlassian’s most successful product features originated in those sessions, not in managed roadmaps with tied incentives.
Why it works: When people feel autonomous, competent, and connected to others (the three core needs in self-determination theory), intrinsic motivation emerges naturally. External pressure crowds those feelings out.
Practical takeaway: For creative, complex work, design for autonomy first. Bonuses and recognition still matter, but they shouldn’t be the primary engine. If you’re a leader, your Leadership Style Quiz results will tell you whether your current style leans toward control or toward building conditions for intrinsic drive.
3. Where Extrinsic Motivation Actually Works
It would be a mistake to write off extrinsic motivation entirely. For routine tasks, early learning stages, and contexts where the activity has no inherent appeal, external rewards and structure are legitimate and effective.
Research published in the Journal of Personality and Social Psychology (1999, Deci, Koestner, and Ryan) conducted a meta-analysis of 128 studies and found that tangible, expected rewards contingent on task completion reliably decreased intrinsic motivation. But verbal rewards, unexpected bonuses, and performance-based praise on well-defined tasks showed neutral or mildly positive effects.
Amazon’s fulfillment center operations under Andy Jassy and Jeff Bezos illustrate the point. Warehouse work, by its nature, doesn’t carry much intrinsic reward for most people. Amazon uses structured extrinsic systems: performance metrics, rate standards, and compensation tied to output. The system works for what it is. No one is arguing Amazon warehouse workers should be motivated by the joy of pulling orders. Extrinsic systems are suited for well-defined, repeatable tasks with clear outputs.
Where Bezos drew the line was in product and technology teams. His famous “working backwards” memos and the emphasis on writing six-page narratives over PowerPoints were designed to protect deep thinking, a zone where intrinsic engagement matters enormously.
Why it works: Extrinsic rewards are most effective when tasks are straightforward, when the person isn’t intrinsically motivated to begin with, and when rewards are contingent on genuine quality rather than mere participation.
Practical takeaway: Match your motivational approach to the task type. Routine work: structure, clarity, fair compensation. Complex or creative work: autonomy, ownership, meaningful challenge.
4. The Motivation Spectrum in Practice: Internalization
Deci and Ryan’s spectrum has a critical middle section that often gets ignored: internalized extrinsic motivation. This is when you do something for external reasons, but those reasons have become genuinely your own.
Consider health. You might start exercising because a doctor told you to (pure external pressure). Over time, it becomes part of your identity. You run because you’re a runner now. The original external prompt has been internalized. The motivation is now functionally indistinguishable from intrinsic motivation in terms of sustainability and engagement.
The best professional development works the same way. Satya Nadella’s transformation of Microsoft from 2014 onward is a case study in this. When he took over, Microsoft’s culture was famously competitive and stack-ranked, a system where employees were motivated primarily by external threat: outperform colleagues or risk being cut. Nadella dismantled stack ranking and replaced it with a “growth mindset” framework (borrowed directly from Carol Dweck’s research). The goal was to shift engineers and product managers from external performance anxiety toward internalized curiosity and learning. Microsoft’s market cap went from roughly $300 billion to over $3 trillion in a decade. That’s not a coincidence.
Why it works: Internalization is the bridge. You can’t always engineer pure intrinsic love for a task. But you can structure environments and narratives that help people connect external responsibilities to their own values and identity.
Practical takeaway: Help yourself and others find the “why it matters to me” connection in work. Not the company’s why. Not the manager’s why. The personal why. Understanding your own motivational patterns starts with knowing yourself, and the Master Mindset Quiz is a useful first diagnostic.
5. Long-Term Sustainability: Which Type Actually Lasts?
Intrinsic motivation is more durable. This is one of the most consistent findings in motivational psychology. When the external reward disappears, so does extrinsically motivated behavior. When the internal reward is the behavior itself, it persists.
A 2014 study published in Psychological Science by Christopher Niemiec and colleagues tracked college students’ goal pursuit over two years. Students chasing intrinsic goals (personal growth, relationships, community contribution) reported higher well-being, vitality, and sustained effort. Those chasing extrinsic goals (money, fame, appearance) showed more anxiety, more dissatisfaction, and more goal abandonment when outcomes fell short.
This has implications for career design. If you’ve optimized your career entirely around salary and status, you’ve built a motivational structure that requires constant external validation to keep running. One bad year, one missed promotion, and the engine stalls.
Warren Buffett has spoken about this directly. His well-known “inner scorecard” philosophy is an applied version of self-determination theory: judge yourself by your own standards, not external approval. He’s repeatedly said he’d be happy doing exactly what he does for free, because the intellectual challenge and the craft of it are inherently satisfying. At 93, he’s still going.
Why it works: Intrinsic motivation creates a feedback loop that doesn’t depend on external conditions. It’s resilient because the reward is never at risk of being taken away.
Practical takeaway: Build your primary motivational architecture around things you find genuinely interesting, meaningful, or challenging. Use external rewards as supplementary fuel, not the main engine.
6. Applying This to Leadership and Team Building
Understanding motivation isn’t just a personal development exercise. If you lead people, you’re in the business of managing motivational environments whether you realize it or not.
The most common leadership mistake is assuming everyone responds to the same motivational inputs. High performers often have strong intrinsic drive already. Layering on performance bonuses and micro-management doesn’t add fuel; it introduces friction. Lower performers on complex tasks often need help connecting the work to something personally meaningful, not just tighter accountability.
Research by Teresa Amabile and Steven Kramer (published in their 2011 book The Progress Principle) analyzed nearly 12,000 daily work diary entries from knowledge workers. The single most powerful motivator across all conditions wasn’t recognition or pay. It was small, visible progress on meaningful work. The act of moving forward on something that mattered was sufficient to sustain high engagement day after day.
This is actionable. Break work into visible progress milestones. Help people see the connection between their daily tasks and outcomes that matter. Remove obstacles that produce stagnation. These are infrastructure changes, not motivational speeches.
Practical takeaway: As a leader, your job is less about motivating people and more about removing the conditions that de-motivate them. Autonomy, mastery, and purpose (Pink’s framework, grounded in Deci and Ryan’s research) are the levers.
Conclusion: Both Forces, Used Correctly
The question isn’t which type of motivation is superior. It’s which type is appropriate for your context, and whether your external incentives are supporting or undermining the intrinsic drive that actually produces your best work.
Use extrinsic structure to get started and to reward execution on well-defined tasks. Use intrinsic design to sustain deep engagement on complex, creative, and long-horizon work. Help yourself and others internalize the connection between responsibilities and personal values. And protect the activities you already love from being overrun by reward systems that hollow them out.
If you want to go deeper into the communication and leadership systems that the most effective executives use to build intrinsically motivated teams, Communication Secrets of Great Leaders and CEOs by Daniel Bulmez covers the deeper system behind how great leaders align people with purpose, not just incentives. It’s the kind of book you read and immediately see the framework everywhere.

Frequently Asked Questions
What is the difference between intrinsic and extrinsic motivation?
Intrinsic motivation comes from within: you engage in an activity because it’s inherently interesting, enjoyable, or meaningful. Extrinsic motivation comes from outside: you do something to earn a reward, avoid a penalty, or gain approval. Both can drive behavior, but they operate differently in terms of long-term sustainability and quality of performance.
Which type of motivation is more effective?
It depends on the task. For creative, complex, and cognitively demanding work, intrinsic motivation consistently produces higher quality results and sustains effort longer. For routine, well-defined tasks, extrinsic rewards can be effective. The mistake is applying extrinsic systems to intrinsically motivated activities, which the research shows can undermine engagement.
What is the overjustification effect?
The overjustification effect occurs when introducing an external reward for an activity someone already enjoys causes them to reattribute their motivation from internal interest to external reward. Once the reward is removed, engagement drops below the original baseline. It was first documented in a 1973 Stanford study by Lepper, Greene, and Nisbett.
What is self-determination theory?
Self-determination theory (SDT) is a framework developed by Edward Deci and Richard Ryan at the University of Rochester. It proposes that human motivation and well-being are driven by three core psychological needs: autonomy (feeling in control of your own actions), competence (feeling effective), and relatedness (feeling connected to others). When these needs are met, intrinsic motivation flourishes.
Can extrinsic motivation become intrinsic?
Yes. This process is called internalization. When you initially do something for external reasons but gradually connect it to your own values and identity, the motivation becomes internalized and functions much like intrinsic motivation in terms of sustainability. Effective leaders and coaches understand how to facilitate this shift.
