Are extraverts less intelligent?

INTRO: Are extraverts less intelligent than introverts, or is the opposite true? According to researchers, introversion-extraversion may affect performance on intelligence tests. Eysenck’s arousal theory (1994) proposes that introverts arouse more easily and therefore are less risk-taking than extraverts, which in turn affects test-taking behaviors. Whereas introverts work more slowly for accuracy, extraverts work more quickly and make more mistakes on intelligence tests. Indeed, researchers found that introverts did better on intelligence tests when it was quiet, whereas extraverts performed worse when it was quiet.
However, the research in this area is far from conclusive. Some studies do not support the arousal theory. In addition, some studies find that extraversion is related to greater intelligence, whereas others (especially more recent studies) find the opposite.
To resolve these mixed findings, Wolf and Ackerman (2005) conducted a meta-analysis of 100 studies for correlations between extraversion and IQ among English speakers. Altogether, there were 166 samples, 1018 correlations, and over 50K participants.
Results indicated that although extraversion had a slight negative correlation with intelligence (predicting lower intelligence), the effect size was extremely small and near zero, indicating a practically unimportant effect. Interestingly, over time, not only did the effect size become smaller, but the correlation became negative instead of positive.
Furthermore, some moderators, such as age, were found to be important... (MORE - details)
