Studies have shown that curiosity positively correlates with intelligence. In one study published in the Journal of Personality and Social Psychology in 2002, researchers correctly predicted that high novelty-seeking (or highly curious) toddlers would have higher IQs as older children than toddlers with lower levels of curiosity. Researchers measured the degree of novelty-seeking behavior in 1,795 3-year-olds and then measured their cognitive ability at age 11. As predicted, the 11-year-olds who had been highly curious 3-year-olds later scored 12 points higher on total IQ compared with low stimulation seekers. They also had superior scholastic and reading ability.
Other studies have shown that high levels of curiosity in adults are connected to greater analytic ability, problem-solving skills and overall intelligence. All of which suggests that cultivating more curiosity in your daily life is likely to make you smarter.
