Curiosity is often described as a foundation of intrinsic motivation, stimulating questions, the desire to understand and the enjoyment of learning new things (Kashdan and Silvia, 2009[21]). Specifically, epistemic curiosity is defined as a motivational drive that is revealed by what a person voluntarily chooses to pay attention to, study, attempt to solve, retrieve or explore in the absence of compelling external needs or incentives (Metcalfe, Schwartz and Eich, 2020[22]). The PISA index of curiosity captures not only students’ drive for knowing how things work, but also their intrinsic motivations to learn and to ask questions.
PISA 2022 data confirm that students with greater curiosity are more likely to report a growth mindset (Table B.21). Yet, here too the relationship diverges by performance group. Low-performing students with a growth mindset are often less curious, perhaps because they may focus on the more “mechanical” aspects of doing better in school (Figure 7). Among mid-performing students, growth mindset students were consistently more curious across countries/economies. Top-performing students with a fixed mindset are typically just as curious as top-performing growth mindset students, perhaps because their curiosity has compensated for any negative impact of a fixed mindset.
Importantly, curiosity also acts as a moderating factor in the link between mindset and achievement – students with greater curiosity show an additional gap of around 12 score points in mathematics related to growth mindset, even after accounting for socio-economic status (Figure 10 and Table B.29).
Persistence, in turn, is clearly associated with growth mindset across countries/economies (Table B.21). The PISA index of persistence measures students’ perseverance and resilience in areas such as putting in additional effort when work becomes challenging or stopping when work becomes too difficult. Persistence and curiosity both operate through a motivational channel that underpins effort and strategic learning.
The relationship between persistence and growth mindset is positive for most students, particularly in the middle performance group, where it is rarely absent or negative. Among low and top performers, the association is often non-significant, yet still positive in some countries/economies, or even negative among low performers.
Like curiosity, persistence enhances the link between growth mindset and mathematics performance, with students in the top quarter of persistence scoring about nine score points higher than those in the lowest quarter in relation to growth mindset, after accounting for students’ socio-economic status (Figure 10 and Table B.31).
This suggests that persistence likely amplifies the motivational impact of growth beliefs. Among low performers, however, they do not channel motivation in the same way. It is possible that when curiosity or persistence is not matched by adequate instructional support or experiences of success, they can even be negatively related to growth mindsets. This pattern suggests that motivational skills may enhance the value of growth beliefs, but only when students’ learning environments provide space for them to be acted upon.
Together, these patterns suggest that growth mindset is most consistently linked with other self-beliefs and dispositions, but typically in the larger group of mid-performing students. Among low performers, associations are weaker or inconsistent, potentially because a student with a growth mindset who still performs poorly might be lacking other motivation or self-regulation skills. Among top performers, these relationships are largely non-significant, but the underlying mechanisms are likely to be different. Confidence in their abilities may already be firmly established, reducing the additional salience of mindset beliefs for self-efficacy. In addition, top-performing students with a fixed mindset might succeed, likely due to other motivational factors, despite their fixed mindsets. In such cases, growth mindset appears less relevant, not because it is absent, but because it overlaps with existing resources that lead to higher performance even among students who endorse a fixed mindset.
