The results of a meta-analysis research conducted in 1997, which consisted of 35 studies, indicated that there is a very small, but statistically significant positive correlation between Extraversion and g (r=.08) [REF].
There are some moderating variables in the relationship between extraversion and g including differences in the assessment instruments and samples' age and sensory stimulation; for example, no meaningful correlation was found between extraversion and intelligence in the samples of children [REF].
