Why Boys Fall Behind: Global Study Ties Academic Slump to Effort Beliefs

Across much of the world, an uncomfortable pattern has taken hold in classrooms: girls consistently outperform boys at school. They earn higher grades, they read better, and they go on to complete university degrees at noticeably higher rates. For decades, researchers have examined this gap through the lenses of school systems, teaching styles, and family circumstances. A new large-scale international study now points to something less tangible but potentially far more consequential: what boys themselves believe about the value of trying hard.

The study, published in PNAS Nexus and authored by Clotilde Napp, draws on two waves of the Programme for International Student Assessment, the triennial survey of fifteen-year-olds conducted by the Organisation for Economic Co-operation and Development. Using data from the 2012 and 2018 assessment rounds, the analysis covers roughly 750,000 students across 61 countries. PISA is unusually valuable for this kind of work because, alongside its tests in mathematics, reading, and science, it asks students an extensive battery of questions about their attitudes, motivations, and home lives. That combination allows researchers to connect what teenagers believe with how they actually perform.

At the heart of the study is a single, deceptively simple survey statement: “Trying hard at school is important.” Students indicated how much they agreed with it, and their answers became a measurable index of attitudes toward academic effort. The finding that emerged was striking in its consistency. In nearly every one of the 61 countries examined, boys were less likely than girls to agree that effort at school matters. This was not a quirk of one education system or one culture; it appeared across a wide range of economic and social settings, suggesting a pattern that transcends national borders.

Crucially, the attitude gap was not merely a survey artifact. Napp found that students’ responses to the effort question were correlated with their individual academic performance, and the link was especially pronounced in reading. Reading is the domain in which boys’ underachievement is most visible worldwide, and the study’s results suggest that a weaker belief in the value of effort may be part of the mechanism behind it. In other words, the students who doubted that hard work mattered tended, on average, to score lower, and boys were disproportionately represented among those doubters.

The geographic texture of the data adds another layer of complexity. The gender gap in attitudes toward effort was larger in more developed countries. That counterintuitive result complicates the assumption that gender inequality in education is primarily a problem of poorer nations. In wealthier economies, where girls already outpace boys in most measures of school success, boys appear particularly disengaged from the idea that diligence matters, raising questions about how modern, affluent societies socialize their sons into particular ideas about schoolwork.

The cross-country comparison also revealed a sobering ecological pattern: in nations where the attitude gap was larger, boys’ relative academic performance was weaker, and their participation in higher education was lower. The alignment held across most of the sample, with one conspicuous exception. The relationship did not extend to STEM fields, where boys’ enrollment and performance patterns follow different dynamics. This exception matters for policy discussions, because it suggests that the effort-belief gap operates most strongly in areas such as reading and general academic engagement rather than uniformly across the curriculum.

Behind the attitude gap may lie a deeper cultural story. According to the study’s author, the pattern is consistent with a persistent stereotype that associates talent and brilliance more with boys, while linking effort, diligence, and conscientiousness more with girls. If brilliance is coded as masculine, then a boy who struggles at school can rationalize his performance as a matter of innate ability rather than insufficient work. If diligence is coded as feminine, then trying visibly hard can feel at odds with a particular version of masculinity. Either way, the stereotype undermines the belief that sustained effort is the path to academic success, and the PISA data suggest that boys around the world have absorbed that message.

The study also examined the role of parents and found a further gendered divide. Boys were less likely than girls to report that their parents strongly supported their academic efforts. This difference in perceived parental support may both reflect and reinforce the attitude gap. Adolescents are sensitive to the expectations and encouragement they perceive at home, and if boys sense less active backing for their schoolwork, the cultural message that effort matters less for them is amplified. Parental behavior, in this framing, is not a separate factor but part of the same web of gendered expectations that shapes how teenagers approach learning.

The scale of the dataset lends the findings considerable weight. Three-quarters of a million students across six decades of countries, surveyed in two separate assessment waves, produce a picture that individual national studies could only sketch in fragments. Earlier research in specific countries had already hinted that boys held more negative attitudes about academic effort; what this analysis adds is the demonstration that the pattern is global, systematic, and quantitatively linked to real differences in achievement and educational trajectories.

For educators and policymakers, the implications are significant. Boys’ underachievement has often been treated as a structural problem solvable through curricular reform or teaching interventions, yet this study suggests that cultural beliefs about gender and effort deserve a central place in the conversation. If boys in developed countries are the most likely to reject the importance of trying hard, and if those beliefs track with poorer reading performance and lower university participation, then interventions aimed squarely at dismantling stereotypes about brilliance and diligence may be among the most effective tools available. The gender gap in education, the study reminds us, is not only about what happens in classrooms; it is about what boys come to believe before they ever sit down to study.
