Does growth mindset training actually work?
✗ Not supported 40 sources reviewed, 27 peer-reviewed
Growth mindset interventions are associated with very small improvements in academic outcomes (d = 0.05-0.11) that fall well below conventional thresholds for practical significance. The most robust studies find effects primarily limited to at-risk students, with minimal or no benefits for general student populations.
What would prove this wrong?
A large-scale RCT with diverse student populations showing growth mindset interventions producing effect sizes d ≥ 0.20 across multiple academic outcomes for general (not just at-risk) student populations
Open questions
Effect sizes consistently fall below thresholds for practical educational significance
Benefits limited to specific at-risk populations rather than generalizing broadly
High-profile replication failures suggest original effect sizes were substantially overestimated
What the evidence says
Has Issues
#1
Meta-analyses reveal that growth mindset interventions produce only small effect sizes (typically d < 0.1) that are not practically meaningful despite being statistically significant in some studies.
Growth mindset interventions may be especially beneficial for certain populations despite overall small effect size
Has Issues
#2
The majority of replication attempts of foundational growth mindset studies have failed to reproduce the original positive effects, indicating the interventions may not be as robust or generalizable as initially claimed.
Meta-analysis of 273 studies (N = 365,915) examined the relationship between mindset and academic achievement
Has Issues
#3
Growth mindset interventions show inconsistent results across different populations, with benefits appearing primarily in highly specific contexts (such as students from disadvantaged backgrounds in particular school settings) rather than producing broad, reliable improvements.
Meta-analysis demonstrated very large proportion of heterogeneity in effect sizes, indicating true effect of given study could be substantially higher

Do growth mindset programs actually work in schools?
Research shows growth mindset interventions produce very small improvements in academic outcomes, with effect sizes of 0.05-0.11. These effects fall well below the conventional threshold of 0.20 considered practically meaningful in educational research.
What is a growth mindset intervention?
Growth mindset interventions are educational programs designed to teach students that intelligence and abilities can be developed through effort and practice, rather than being fixed traits. These programs typically involve lessons, activities, or exercises aimed at changing students' beliefs about learning and intelligence.
Do growth mindset programs help all students equally?
Studies indicate that benefits are primarily concentrated among academically at-risk or socioeconomically disadvantaged students. General student populations show minimal or no improvements from these interventions.
How big are the academic improvements from growth mindset training?
The academic improvements are very small, with effect sizes ranging from 0.05 to 0.11. To put this in perspective, educational researchers typically consider effects below 0.20 to be of minimal practical significance in classroom settings.
What don't we know yet about growth mindset interventions?
Key unknowns include the optimal duration and format of interventions, why effects vary so dramatically between different student populations, and whether the small benefits observed persist over longer time periods. Most studies have focused on short-term outcomes rather than long-term academic trajectories.
