Mindset about Talent Moderates the Effect of Grit on Academic Performance: Evidence from West Point Cadets

The United States Military Academy (USMA) at West Point emphasizes developing leaders of character and continually evaluates factors that influence cadet performance. Prior research indicates that grit—perseverance and passion for long-term goals—predicts performance across domains, including academic achievement among Ivy League students and West Point cadets. However, evidence on the magnitude of grit’s effects is mixed, and entrance exam scores often remain the strongest predictor of academic outcomes. Mindset theory posits that beliefs about the malleability of traits (fixed vs. growth) shape motivation, goal choice, and responses to feedback. While growth mindset is generally associated with better academic outcomes, effect sizes are often small and context-dependent. The present study aimed to extend understanding of grit’s role in academic achievement within a military education context by testing whether mindset about talent moderates the relationship between grit and academic performance at West Point. The authors hypothesized that mindset about talent would moderate the relationship between grit and (a) first semester academic performance and (b) final cumulative academic performance, above and beyond entrance exam scores, physical fitness (CFA), and grit.

Research has linked grit to performance across numerous domains, though meta-analytic findings suggest modest associations overall. In West Point cohorts, entrance exam scores typically best predict academic achievement, with grit and physical ability adding incremental variance. Mindset research, largely focused on intelligence, indicates that a growth mindset correlates with better academic performance, challenge-seeking, and course-taking, though there are null results and small overall effects in meta-analyses. Large-scale work (e.g., the National Study of Learning Mindsets; Yeager et al., 2019) shows growth mindset benefits particularly for lower-achieving students, and PISA 2018 reported positive relationships in most participating countries. Prior to this study, the potential moderating role of mindset about talent in the grit–academic performance link at West Point had not been examined. The literature also notes modest positive correlations between grit and growth mindset in U.S. student samples, with stronger correlations reported in some Chinese samples, and evidence that grit and growth mindset may influence each other developmentally.

Participants: The initial sample comprised all cadets (N = 1262) in the West Point Class of 2019. Demographics were approximately 22% female, 61% Caucasian, 12% African American, 11% Hispanic/Latino, 8% Asian, and 8% other/multiracial, with mean age 18.35. With IRB exemption and USMA approval, institutional records provided study data. Cadets with missing/incomplete data were excluded, yielding a final sample of 1140 with similar demographics.

Procedure and Measures: During the second or third day of summer training in 2015, cadets completed an assessment battery including the eight-item Grit-S (Duckworth & Quinn, 2009) and three items measuring mindset about talent (Dweck, 2006). Grit-S includes four perseverance and four consistency-of-interest items rated 1–5 (“not at all like me” to “very much like me”); after reverse coding, items were averaged (higher scores = more grit). Mindset items assessed beliefs about the malleability of talent (e.g., “You have a certain amount of talent, and you can’t really do much to change it.”), rated 0–5 (0 = strong disagreement to 5 = strong agreement). All mindset items were negatively worded and reverse coded so low scores reflected fixed mindset and high scores reflected growth mindset. Reliability: Grit-S α = 0.74; mindset α = 0.93.

Entrance exam: Highest SAT (with ACT converted to SAT scale via ACT/SAT concordance). Physical ability: Cadet Fitness Assessment (CFA; six timed tests, e.g., one-mile run, pull-ups) administered prior to arrival in 2015. Outcomes: First semester academic program score (APST1) and final cumulative academic program score at graduation (APSC).

Analytic Strategy: Two hierarchical multiple regressions were conducted with APST1 and APSC as dependent variables. Step 1 predictors: entrance exam score, CFA, grit. Step 2: mindset. Step 3: grit × mindset interaction. Continuous predictors and the interaction term were mean-centered. Missing data were examined for MCAR; 30 datasets were imputed to compare pooled estimates with complete-case analyses. Results were substantively similar for APST1 and APSC; CFA predicted APSC only in imputed analyses, not in complete-case. Because differences did not involve grit, mindset, or their interaction, complete-case results were presented as the more conservative approach.

• Descriptives/correlations (selected): Grit correlated positively with mindset (r = 0.19, p < 0.001). Entrance exam correlated negatively with mindset (r = -0.12, p < 0.001) and with grit (r = -0.09, p < 0.001). CFA correlated modestly with entrance exam (r = 0.08, p < 0.01) and mindset (r = 0.06, p < 0.05).

• APST1 (first semester) regression (N = 1112): • Step 1: Entrance exam (β = 0.63, p < 0.01), grit (β = 0.11, p < 0.01), and CFA (β = 0.09–0.10, p < 0.01) significantly predicted APST1; R² = 0.648. • Step 2: Mindset did not improve prediction; R² unchanged (0.648). • Step 3: Grit × Mindset interaction significant (B = -0.07, SE = 0.02, β = -0.08, p < 0.01), increasing R² to 0.653; mindset moderated the grit–APST1 relationship. • Simple slopes (mindset ±1 SD): Fixed mindset (−1 SD) slope B = 0.234, SE = 0.039, p < 0.001; Growth mindset (+1 SD) slope B = 0.044, SE = 0.041, p = 0.283.

• APSC (final cumulative) regression (N = 959): • Step 1: Entrance exam (β = 0.61, p < 0.01) and grit (β = 0.09–0.10, p < 0.01) predicted APSC; CFA did not. R² = 0.606. • Step 2: Mindset did not improve prediction (R² = 0.606). • Step 3: Grit × Mindset interaction significant (B = -0.04, SE = 0.02, β = -0.07, p < 0.01), increasing R² to 0.610; mindset moderated the grit–APSC relationship. • Simple slopes (mindset ±1 SD): Fixed mindset (−1 SD) slope B = 0.131, SE = 0.030, p < 0.001; Growth mindset (+1 SD) slope B = 0.026, SE = 0.030, p = 0.397.

• Overall: Entrance exam scores were the strongest predictors of academic outcomes. Grit consistently predicted both APST1 and APSC. Mindset showed no main effect but significantly moderated the grit–performance relationship at both time points, with the strongest positive association between grit and performance observed among cadets with more fixed mindsets about talent.

Findings replicate and extend prior work at West Point showing that entrance exam scores are the strongest predictors of academic performance, with grit contributing incremental variance. Crucially, mindset about talent moderated the relationship between grit and both early (first semester) and cumulative academic performance. Contrary to the expectation that a growth mindset combined with high grit would yield the highest achievement, the association between grit and performance was strongest for cadets with fixed mindsets. For cadets endorsing a fixed mindset, higher grit was associated with markedly better performance, whereas for those with growth mindsets, the grit–performance association was not significant. These results suggest that the effectiveness of grit for academic success depends on cadets’ beliefs about the malleability of talent, and that interventions may need to consider both constructs jointly. For example, bolstering grit or reducing fixed mindset among low-grit cadets may be beneficial, while promoting growth mindset among highly gritty cadets might, paradoxically, attenuate the achievement advantage observed among gritty fixed-mindset cadets in this context.

The study demonstrates that mindset about talent moderates the relationship between grit and academic performance at West Point. Specifically, a fixed mindset was associated with the strongest positive relationship between grit and both first semester and cumulative academic outcomes; gritty cadets with fixed mindsets outperformed their less gritty fixed-mindset peers. Thus, the impact of grit on academic performance depends on mindset about talent. Future research should examine the developmental interplay between grit and mindset in military education settings, clarify whether fixed-mindset cadets perceive their talent as fixed at high versus low levels, and identify the mechanisms through which mindset shapes the grit–performance link.

Key limitations include: (1) The study could not determine whether cadets with fixed mindsets believed their talent to be fixed at high or low levels, limiting interpretation of how perceived talent level interacts with grit; (2) The mechanisms by which mindset moderates the grit–performance relationship remain unspecified; and (3) Although missing data analyses (imputation vs. complete-case) yielded largely consistent results, CFA predicted cumulative performance only in imputed data, not in complete-case analyses, indicating some sensitivity to missing data handling for that predictor.
