Abstract
The four scales of the Myers‐Briggs Type Indicator, (Extraversion‐Intro‐version, Sensation‐Intuition, Thinking‐Feeling, and Judging‐Perceiving) were intercorrelated with a battery of 32 tests, including 15 ability tests, 7 experimental interest tests and 10 scales taken from the Personality Research Inventory. Ss were high school students (319 males, 252 females) in Massachusetts. Factor analyses, for males and females separately, showed that the Indicator scales as a set were linked with ability, interest and personality variables. Comparison of the analyses revealed some sex differences; the results are interpreted as indicating that all four scales reflect some surface characteristics other than the typological differences for which they were constructed.
