Decades of research have challenged the idea that high intelligence alone predicts success in school and career. Non-cognitive skills matter just as much. This landmark study is the first to systematically review all available literature on how these skills in children aged 12 or younger influence later outcomes, including academic performance, cognitive abilities, and language development.
"Psychologists, economists, and epidemiologists have extensively studied childhood traits like attention, self-regulation, and perseverance, demonstrating their impact on future success," says the study's senior author.
"Evidence clearly supports the role of non-cognitive skills in later-life achievements, yet results across studies remain inconsistent," he adds.
One co-author explains: "Published research provides preliminary links between non-cognitive skills and academic success, psychosocial adjustment, cognitive, and language outcomes—while underscoring that cognitive skills are still crucial."
The review's strongest insight? Evidence quality falls short. From over 550 eligible studies, only about 40% met acceptable standards.
