Tomorrow's Professor: Is Intellectual Curiosity a Strong Predictor for Academic Performance?

Is Intellectual Curiosity a Strong Predictor for Academic Performance?

What Does Research Tell us about Academic Performance and Curiosity?

For better or worse, academic performance has long stood as a proxy for general aptitude. To understand what factors affect academic performance gives us a better understanding of how instructors can help students achieve their greatest potential in college. Empirical evidence strongly suggests that academic performance can be predicted by a combination of cognitive ability (or intelligence) and effort. Non-ability personality traits, such as effort, can be potentially more meaningful than intelligence because less able students can compensate for lower levels of cognitive ability by becoming more conscientious, studying harder, and paying greater attention to details and rules. Beyond cognitive ability and effort, researchers look to so-called investment traits to explain inter-individual differences among people?s drive to pursue, enjoy, and engage in learning opportunities. Intellectual curiosity conveniently describes this impulse, as does the researcher?s titular phrase,
the hungry mind.? Like cognitive ability and effort, intellectual curiosity positively associates (at medium effect sizes) with academic performance.

Several instruments have been developed to measure something like curiosity. The ?Need for Cognition? scale measures the ?tendency for an individual to engage in and enjoy thinking? (Cacioppo & Petty, 1982, p. 116). The ?Typical Intellectual Engagement? (TIE) scale was designed to ?differentiate among individuals in their typical expression of a desire to engage and understand their world, their interest in a wide variety of things, and their preference for a complete understanding of a complex topic or problem, a need to know?.? (Goff and Ackerman, 1992, p. 539). Because these measures have similar conceptual underpinnings and share criteria validity for academic performance and intelligence, they appear to measure the same trait dimension, and studies that use these scales can be rolled into a meta-analysis.


Study & Methods

To investigate whether curiosity is a strong determinant for academic performance, Von Stumm, Hell, & Chamorro-Premuzic extracted correlation coefficients from three previous studies and performed four meta-analyses that focused on TIE to stand in for curiosity. For the new TIE meta-analyses, the researchers selected 11 studies (including several in which one of the authors had participated). They excluded studies that did not include empirical data, did not include zero-order correlations, or included previously reported data. In these studies, academic performance was expressed as either grade point average or an academic performance composite. From the extracted correlation coefficients and the new meta-analyses, the authors created five path models using a stepwise process, settling on a single, best-fit model.



The best fitting model indicated that intelligence, TIE, and conscientiousness were direct and intercorrelated predictors of academic performance. Within this model, intelligence (.35) accounted for the greatest amount of variance while curiosity (.20) and effort (.20) had slightly smaller and equal and independent impacts on academic performance. (The preceding measurements are standardized beta weights.) The authors thus confirm their hypothesis that intellectual investment, including curiosity, is a key determinant of academic performance.


Discussion and Implications

The authors suggest several important ramifications of this finding:

? Academic performance can be increased if students? intellectual curiosity is regularly renewed and stimulated. Thus, students should be

encouraged to follow challenging paths and not be exclusively rewarded for their ?acquiescent application of intelligence and effort.? Universities

and colleges should seek to exploit opportunities to inspire curiosity and reward productive novelty.

? Admissions officers should pay attention to intellectual curiosity as a strong predictor of potential.

? Future studies to examine predictors of academic success should seek to expand their range beyond intelligence and effort.



Technology may have a role in cultivating curiosity by providing greater access to new information, new ways to participate in culture through new media (Jensen et al, 2006), and novel methods of visualizing data. Curiosity might also have a role to play in orienting students toward life-long learning, which has already been shown to be influenced by such pedagogical practices as active learning, reflection, and tasks that encourage perspective-taking (Mayhew, M.J., Wolniak, G.C., & Pascarella, 2008).


Study Limitations

As the authors note, the study is constrained by several factors, including the quality of the original studies in the meta-analyses. Further, only conscientiousness was used as a proxy for effort, ignoring academic motivation, self-efficacy, and ambition. The study also did not consider the cumulative effect of success as an ongoing magnifier for conscientiousness and curiosity. To correct for this, another study would have to consider the longitudinal effects of an academic course of study and not a single moment. Finally, the authors concede that despite the encouraging results that showed that conscientiousness and intellectual curiosity combined influenced academic performance to the same degree as intelligence, other variables likely to have an effect, such as choice of subject, socio-economic status, self-confidence, etc., were not factored into a final model. Seen in the context of these limitations, the study directs researchers to continue to explore the nexus of no

 n-ability personality traits with intelligence to predict academic performance.
