Are introverts smarter than extroverts? I wouldn't really agree to that because it all boils down to the individual. But, introverts are seen to be smarter because they hardly talk, and when they do talk, they talk sense because they've thought it over and over, possibly over thought it before giving a reply. Is that the definition of smart? Yea but that does is not a determinant as to who's smarter. Smartness is subjective
