“Personality Differences in Gifted versus Non-Gifted Individuals: A Three-Level Meta-Analysis”, 2021-11-07 (; similar):
Some research has investigated the Big Five personality dimensions among gifted individuals, but these individual studies have provided inconclusive results.
The current meta-analysis examined the nature of the relationship between the Big Five dimensions and giftedness among individuals. Hedge’s unbiased g was used as the effect size metric, and a 3-level multilevel meta-analytic approach was applied, due to the dependency among the effect-sizes obtained from the same study.
The analyses used 82 effect sizes, from 13 published studies, and indicated that there was a statistically-significant difference between gifted and non-gifted participants in terms of Openness to Experience in favor of gifted individuals (g = 0.473, p = 0.005, 95% CI [0.199, 0.747]). However, there were no statistically-significant differences in terms of Extraversion, Agreeableness, Conscientiousness, and Neuroticism.
The implications and limitations of the findings are discussed.
