A student’s “K-factor” predicts university GPA beyond SAT scores and personality

A new study reveals that the "K-factor"—a measure of future-oriented and long-term life strategies—predicts university GPAs. This metric forecasts academic success even after accounting for SAT scores and personality traits.

A new study published in Evolutionary Psychological Science reports that students who scored higher on the K-factor tended to have higher university GPAs, even after accounting for SAT scores, personality traits, and parent education. Although standardized test scores, personality traits, motivation, study habits, and self-regulation are already known to predict university performance, researchers are still interested in identifying additional psychological factors that help explain why some students do better than others. This research focuses on one such factor: the K-factor, a psychometric measure rooted in life history theory.

Broadly, life history theory asks how people allocate limited time and energy across competing demands, such as learning, health, relationships, planning for the future, and immediate rewards. In this context, the K-factor is treated as a marker of a more future-oriented, socially connected, and long-term strategy, which could plausibly support academic success. Tyler L. Minnigh and colleagues examined whether the K-factor predicts university GPA above and beyond better-established predictors, including SAT scores, Big Five personality traits , broader personality composites, and parent education.

While many studies have examined intelligence and personality as predictors of academic achievement, no prior work has directly tested whether a psychometric life history measure predicts university academic performance. The
