The Myers-Briggs Type Indicator® (MBTI) is a psychometric test used to measure psychological preferences in how a person makes decisions and perceives their surrounding environment. A mother-daughter pair, Katherine Briggs and Isabel Myers developed the test based on the typological theories of Carl Gustav Jung. After more than fifty-years of research and development, the MBTI has become the most widely used and respected personality tool. Eighty-nine companies out of the US Fortune 100 make use of it for recruitment and selection, or to help employees gain a better understanding of themselves and their colleagues (Psychometric Success, 2013).

When a person changes type on the retest, it is usually on one of the dichotomous pairs, and in a pair where the preference clarity was low. Numerous studies of the standard MBTI Form M, have yielded reliability coefficients of 0.90 or greater for its four scales (Schaubhut, 2009). From these results, one can infer the MBTI is a reliable assessment. Validity is the degree to which a test measures what it is intended to measure. Thus the MBTI’s validity is the extent to which the test measures attributes or qualities that people are presumed to possess. Several studies with substantial evidence have shown results that are consistent with Jung’s Theory. The validity of a MBTI score is established by correlating the scores with findings from similar personality assessments. Statistically significant correlations have been found between MBTI scores,
