Growth mindset vs. fixed mindset: What Carol Dweck really found

Do you know that feeling when you fail at a task and immediately wonder if you’re just “not cut out for it”? Or have you ever told yourself that math, sports, or creative writing “aren’t for you”—and never questioned that belief again? This is exactly where one of the most influential theories in modern psychology comes in: the distinction between a growth mindset and a fixed mindset. Through decades of research, developmental psychologist Carol Dweck has shown that our deepest beliefs about intelligence and abilities have a profound influence on how we learn, cope with challenges, and develop as people. This article explains what Dweck actually discovered—beyond the simplified self-help versions.

Two Core Beliefs That Change Everything

The core of Dweck’s theory is surprisingly simple, yet its implications are far-reaching. In her 2006 book *Mindset: The New Psychology of Success*, Carol Dweck explains that people essentially have two different belief systems regarding their own abilities and intelligence.

People with a fixed mindset believe that intelligence, talent, and fundamental character traits are innate and unchangeable. Those who are smart are smart—those who aren’t won’t become so. Mistakes are interpreted as proof of a lack of ability, and challenges as a risk of exposing one’s own failure. The result: people avoid difficult tasks, give up quickly, and react defensively to criticism.

People with a growth mindset, on the other hand, are convinced that abilities can be developed through effort, good strategies, and support from others. Intelligence is not a fixed quantity but a malleable process. Mistakes are seen as learning opportunities, setbacks as a necessary part of growth. These individuals actively seek out challenges because they know: that is exactly where development takes place.

As Dweck emphasizes: It’s not about whether someone thinks positively all the time. It’s about the deeper conviction that change is even possible.

How Carol Dweck Developed Her Theory

Carol Dweck didn’t start her career with a fully formed theory in mind. In the 1970s and 1980s, she was fascinated by how differently children reacted to failure. While some children gave up on difficult tasks or blamed themselves, others seemed to really thrive when things got harder. These children said things like, “I love a challenge” or “I have to try that again.”

Dweck and her colleague Ellen Leggett developed a theoretical model based on these observations, which they published in 1988 in the groundbreaking paper “A Social-Cognitive Approach to Motivation and Personality” (Dweck & Leggett 1988). In it, they described two fundamental goal patterns: growth goals (the desire to expand one’s abilities) and performance goals (the desire to be seen as competent). Those who pursue growth goals seek out challenges. Those who prioritize performance goals avoid situations where their own failure might become apparent.

This early model was the precursor to what Dweck would later popularize as fixed and growth mindsets—and it was empirically grounded from the start, not speculative.

What the Studies Really Show: Praise, Intelligence, and Performance

One of the best-known lines of research in Dweck’s work concerns the effect of praise. In a widely cited study (Dweck 2006, based on experiments from the late 1990s), children were divided into two groups. After completing a task, the first group received praise for intelligence (“You’re really smart”), and the second group received praise for effort (“You worked really hard”).

The result was striking: children who were praised for their intelligence subsequently avoided more difficult tasks—they wanted to protect their “smart” image. Children who were praised for their effort, on the other hand, actively sought out more challenging tasks. They showed a greater willingness to learn, more perseverance, and ultimately achieved better results.

This finding has enormous practical implications: How we praise children (and ourselves) influences the type of belief system we develop. Praising intelligence fosters a fixed mindset. Praising effort fosters a growth mindset.

Importantly, Dweck never claimed that praise is inherently harmful. It depends on what is being praised—the process, the strategy, and the perseverance, or the innate outcome.

Key message of the research „In a growth mindset, students believe that their most basic skills can be developed - through dedication and hard work. This creates a love of learning and a resilience that is essential for great achievement.“ - Carol Dweck, Mindset: The New Psychology of Success (2006)

Growth Mindset in Schools: What Yeager and Dweck Found

One particularly important area of research addresses the question: Can a growth mindset be specifically fostered—and does this have measurable effects on academic performance? David Yeager and Carol Dweck explored this question in an influential review article from 2012 (Mindsets That Promote Resilience: When Students Believe That Personal Characteristics Can Be Developed).

Their analysis showed that interventions designed to foster a growth mindset—especially among adolescents during transitional phases such as the transition to secondary school—can have measurable positive effects on academic performance, motivation, and coping with setbacks (Yeager & Dweck 2012). What was crucial here was not only what students believed about their abilities, but also what they believed about their character, their social skills, and their sense of belonging: Can I change? Do I belong? Can I learn more?

In the years that followed, these studies formed the basis for numerous educational programs worldwide. But as is often the case in psychology, the initial enthusiasm was followed by critical scrutiny—and that is important.

The Criticism: What the Meta-Analysis by Sisk et al. Shows

Science thrives on scrutiny—and that’s a good thing. In 2018, Victoria Sisk and her colleagues published a comprehensive meta-analysis that evaluated over 400 studies on the topic of growth mindset (To What Extent and Under Which Circumstances Are Growth Mind-Sets Important to Academic Achievement?, Sisk et al. 2018). The results were sobering yet nuanced.

The average correlation between growth mindset and academic performance was weak to moderate overall. The effects of mindset interventions on academic performance were also generally small. This means: Having a growth mindset does not guarantee better grades, and training in this area is not a panacea.

But—and this is crucial—Sisk et al. also found that the effects were significantly stronger among certain groups: students from low-income backgrounds and those who were particularly at risk academically. This means that a growth mindset does not have the same impact on everyone, but it can be especially valuable where external conditions are already difficult.

These findings do not fundamentally contradict Dweck’s theory—but they do call for nuance and humility when making promises.

A Common Misunderstanding: The Popular Distortion

Carol Dweck’s theory has undergone a transformation in popular culture that sometimes makes it barely recognizable. The growth mindset has become a mantra in companies, schools, and self-help books—often in a highly simplified form. Dweck herself has publicly criticized these simplifications on multiple occasions.

Common misunderstandings at a glance:

• “Just think positively”: A growth mindset does not mean convincing yourself that you can do anything if you just smile enough. It is about the realistic belief that skills can grow through effort, good strategies, and help from others.
• “Effort is enough”: Dweck has emphasized that mere perseverance is of little use without the right strategies. Those who repeatedly use the same ineffective method will not improve. Smart adaptation is also needed.
• “Anyone can become anything”: The theory does not claim that every person can become an Olympic champion or a Nobel laureate. It says that within one’s own potential, significantly more is possible than a fixed mindset allows.
• “A fixed mindset is evil”: Dweck emphasizes that no one has exclusively a growth or fixed mindset. We all have different beliefs in different areas of life—and that’s normal. The work lies in recognizing rigid beliefs where they harm us.

The true message of the research is more nuanced, but that’s precisely why it’s more enduring: beliefs about changeability influence our behavior—and this behavior actually influences outcomes.

Recognizing a Fixed Mindset: How Does It Manifest in Everyday Life?

Theory is one thing; lived experience is another. How does a fixed mindset actually manifest itself? Mia knows this from her own experience: “For years, I believed I wasn’t good with numbers. I avoided jobs that involved statistics—until I eventually realized that I didn’t even know if I could do it or not. I had never really tried.”

Typical patterns of a fixed mindset in everyday life:

• You avoid tasks where you’re not sure if you can handle them.
• Criticism feels like a personal attack, not useful feedback.
• When others are better than you, you feel envy instead of curiosity or admiration.
• You give up quickly when something doesn’t work out right away—and interpret that as a sign of a lack of talent.
• You define yourself largely by your achievements: When you fail, you feel like a failure.

These patterns aren’t character flaws. They’re often learned reactions to experiences we had as children—in families, schools, or with peers who, without meaning to, pigeonholed us.

Developing a Growth Mindset: What the Research Recommends

The good news is: Beliefs are—at least in part—changeable. Dweck’s research and the intervention literature based on it offer some concrete guidance on how to cultivate a growth mindset in everyday life. The key point is this: It’s not about a one-time exercise, but rather a gradual change in thinking habits.

1. Observe your inner voice

The first step is awareness. When does the voice pop up that says, “This isn’t for me” or “I’m not good enough”? Dweck recommends not fighting this voice, but acknowledging it—it’s the fixed mindset part of us. And it’s okay for it to be there. The only question is whether we follow it.

2. Focus on the process rather than the result

Instead of asking yourself, “Was I good?”, ask yourself: “What did I learn today? What would I do differently next time?” This simple shift in focus—away from judgment, toward the process—is one of the most powerful levers for increasing your willingness to learn.

3. Use the word “yet”

A small linguistic shift with a big impact: “I can’t do this” becomes “I can’t do this yet.” The “yet” opens the door to possibility. Dweck calls this the “power of yet”—and it sounds trivial, but anyone who applies it consistently will notice how it shifts their inner attitude.

4. Accept effort as part of the journey

A growth mindset doesn’t mean that everything should be easy. It means viewing difficulty as a normal part of learning, not as a sign that something is wrong with you. Those who tell themselves, “This is hard for me, so I’m learning right now,” perceive effort differently.

5. Seek feedback instead of avoiding it

People with a strong growth mindset actively seek feedback—even when it’s uncomfortable. They understand that criticism contains information that can help them improve. This is an attitude you can practice: Ask specifically for feedback, and practice taking it in stride.

Growth Mindset in the Workplace: More Than Just a Corporate Buzzword

No other sector has embraced the term “growth mindset” as quickly as the workplace. Hardly any corporate coaching program today can do without it. But here, too, it’s worth taking a closer look.

In her research, Dweck has pointed out an important distinction: There are individual mindsets, but also organizational mindsets—that is, the collective belief within a company regarding whether employees’ skills can be developed. In organizations with a growth mindset, employees experience greater trust, a greater willingness to take risks, and a greater enthusiasm for innovation. In companies with a fixed mindset—where only “talent” counts and mistakes are punished—a culture of self-promotion emerges instead of genuine learning.

The problem: Many companies pay lip service to the term “growth mindset,” while their actual structures—rigid hierarchies, intolerance of mistakes, and short-term performance metrics—promote the opposite. A growth mindset isn’t just a poster on the office wall. It’s evident in how mistakes are handled, how feedback is given, and whether learning is truly given the time and space it needs.

An Honest Assessment: What Dweck’s Research Can Achieve—and What It Cannot

Carol Dweck’s life’s work is scientifically significant and practically relevant. The basic idea—that our beliefs about changeability shape our behavior—is solidly supported by decades of research. And the implications that arise from this are not trivial: how we praise children, how we frame mistakes, how we approach difficulties—all of this has demonstrable consequences.

At the same time, the meta-analysis by Sisk et al. (2018) calls for humility. A growth mindset is not a magic bullet. It does not replace good teachers, supportive structures, fair access opportunities, or material security. Those facing difficult life circumstances need more than a new inner conviction—they also need changed external conditions.

What Dweck’s research does achieve, however, is show us that a willingness to learn is not a matter of talent. That we do not have to be slaves to our beliefs. That it is worth examining the internal narratives we tell ourselves—and whether these stories help or hinder us.

And in a world full of challenges, that is a deeply encouraging message.

Your concrete call to action: Take five minutes tonight and write down one area of your life where you believe, “I just can’t do that.” Then add the word “yet.” And ask yourself: What would be one small step you could take in the next seven days to actually learn something in this area—not to become perfect, but just to get started?

What is the difference between a growth mindset and a fixed mindset?

People with a fixed mindset believe that their intelligence and abilities are innate and unchangeable. People with a growth mindset are convinced that abilities can grow through effort, appropriate strategies and support. Carol Dweck showed in her research that this basic belief influences how we deal with challenges, mistakes and criticism.

Has Carol Dweck really proven that Growth Mindset improves school performance?

Dweck's own studies show significant correlations between growth mindset and learning behavior, perseverance and school performance. However, the meta-analysis by Sisk et al. (2018), which evaluated over 400 studies, calls for differentiation: the average effects are moderate and interventions do not have the same impact on all groups. The positive effects are particularly strong for pupils from disadvantaged backgrounds.

Can you really change your mindset - or is that just theory?

Yes, beliefs can be changed - both Dweck's research and the intervention literature show this. However, it takes more than a one-off awareness-raising exercise. It involves consistent observation of one's own thought patterns, small linguistic shifts (such as adding «yet»), focusing on processes rather than results and actively seeking out challenges and feedback. Change is possible, but it takes time and practice.

Is a fixed mindset fundamentally bad?

No - and this is an important point that Dweck himself emphasizes. No one has exclusively a growth or fixed mindset. We all have different beliefs in different areas of life. In some areas, a fixed mindset does little harm; in others - where we want or need to grow - it can limit us considerably. The aim is not to eradicate the fixed mindset, but to recognize it and deal with it consciously.

How should children be praised to promote a growth mindset?

Dweck's research suggests praising the process rather than the result. So not «You are so clever», but «You have developed a good strategy» or «I see how persistently you have worked at it.» In this way, children learn that effort, planning and perseverance - not innate talent - are the key to learning. This strengthens their willingness to learn and makes them more resistant to setbacks.

What does science criticize about Dweck's theory?

The main criticism concerns the translation into practice: in popular reception, the concept has been greatly simplified - as if positive thinking or enough effort alone were the key to success. Scientifically, the meta-analysis by Sisk et al. (2018) shows that the overall effects are more moderate than often claimed. There is also criticism that the focus on individual beliefs can mask structural inequalities: Those who learn under difficult conditions need more than a different mindset - they also need supportive structures.
