The Meyers-Briggs test is a well known personality test that is often used in the workplace to identify employees’ different personality styles. This test uses all three polarities mentioned above, extroversion vs. introversion, thinking vs. feeling, intuition vs. sensation, and adds one more, judgment vs. perception. Extroversion is also measured on scales associated with the Five Factor Model of personality, such as the NEO personality inventory. This test, formulated to identify dimensions of personality in non-pathological adults, uses 240 items to quantify five areas: neuroticism, extroversion, openness to experience, agreeableness, and conscientiousness.
