Growth Mindset and Intelligence: Does Believing You Can Improve Actually Help?
IQLast updated: July 17, 2025
What is growth mindset?
Growth mindset is the belief that intelligence and abilities can be developed through effort, learning, and persistence, as opposed to fixed mindset, the belief that these traits are innate and unchangeable. Carol Dweck's research (Stanford, since the 1980s) has shown that students who hold a growth mindset achieve more, bounce back better from failure, and seek more challenging tasks. The concept has become one of the most applied in educational psychology.
What does the research actually show?
The original research shows consistent associations between growth mindset and:
- Greater academic persistence
- Better response to failure
- Higher academic achievement (moderate effect sizes)
However, more recent meta-analyses are more cautious:
| Study Type | Finding |
|---|---|
| Dweck & colleagues' original studies | Consistent, large effects |
| Pre-registered replications (2019 Yeager et al.) | Moderate effects in disadvantaged students |
| 2018 meta-analysis (Sisk et al.) | Small overall effect (d ≈ 0.10) |
| High-quality school-based interventions | Effects strongest for at-risk students |
The honest picture: growth mindset is real and matters, but the effect sizes in high-quality replications are smaller than early research suggested, and it is not a magic fix.
What growth mindset is not
- It does not mean "you can achieve anything with enough effort"
- Effort alone is insufficient, effective strategies and good teaching matter as much
- Praising effort indiscriminately (rather than effective strategies) does not reliably produce growth mindset benefits
- It does not eliminate the role of innate talent and genetic factors
Practical implications
- Focus praise on strategies, not effort or traits: "You tried a different approach and it worked" is more effective than "you're so smart" or simply "you worked hard"
- Frame challenges as learning opportunities: not "you failed" but "what would you try differently?"
- Model it: teachers and parents who openly discuss their own learning from failure communicate it powerfully
Frequently Asked Questions
Can adults develop a growth mindset?
Yes. Mindset is not fixed. Adults who reflect on their implicit beliefs about intelligence and actively practice reframing can shift toward a growth orientation. Therapy and coaching often address this.
Does having a growth mindset actually change intelligence?
Not directly, but it changes behavior (persistence, challenge-seeking, learning strategy) in ways that accumulate into real skill development over time.
