A relationship between neurotic tendency and introversion has been around since 1924 insofar as test instruments are concerned (we are not concerned herein with speculation per se). Does it still persist? The writer has recently found a significant relationship between Eysenck's main scales for these tendencies which persists despite Eysenck's efforts to obtain scale independence. Similarly, Comrey, who has developed more recent measures of introversion and neuroticism, reports a correlation of .41. We need to know more about the components of sociability-directed scales for extraversion-introversion as well as about bridging factors such as inferiority.
