Big Five personality traits and academic performance: A meta-analysis

Area of Science:

• Educational Psychology
• Personality Psychology

Background:

• Academic performance is influenced by a complex interplay of cognitive and non-cognitive factors.
• Understanding the role of personality traits in academic success is crucial for developing effective educational strategies.

Purpose of the Study:

• To conduct the most comprehensive meta-analysis on the relationship between Big Five personality traits and academic performance.
• To assess the incremental validity of personality traits in predicting academic performance beyond cognitive ability.

Main Methods:

• Synthesized data from 267 independent samples, totaling 413,074 participants across 228 studies.
• Employed meta-analytic techniques to quantify the strength of relationships.
• Examined the unique contribution of personality traits after accounting for cognitive ability.

Main Results:

• Combined cognitive ability and personality traits explained 27.8% of academic performance variance.
• Cognitive ability was the primary predictor (64% relative importance).
• Conscientiousness was a robust predictor, accounting for 28% of the explained variance, even when controlling for cognitive ability. Effect sizes for openness, extraversion, and agreeableness varied by education level, with larger impacts in earlier schooling.

Conclusions:

• Personality traits play a critical role in academic performance.
• Conscientiousness is a significant predictor of academic success, independent of cognitive ability.
• The influence of certain personality traits on academic performance is moderated by educational level, particularly in early schooling.
