MBTI is based on eight hypothetical assumptions and until this day there has been no scientific proof to support the claims of the method.

They developed their work to a commercial test in 1975 then sold the test and the manual to Consulting Psychologists Press (CPP). The work attracted the attention of Henry Chauncey, head of the Educational Testing Service. Neither Myers nor Briggs were formally educated in psychology and lacked scientific credentials in the field of psychometric testing. Soon she was joined by Isabel Briggs Myers, who added the different personality types based on the then recent work of Carl Jung. In 1917, Katharine Cook Briggs began research into personalities to determine her future son-in-law’s personality. The scientific grounds for the MBTI test are missing Unfortunately, the test is often used as a final and unchangeable description of someone’s personality.ġ. The test is too limited to give an idea about your overall personality (this usually takes months of testing). It is not a definitive verdict on someone’s personality. Over the past 2 decades, MBTI has become increasingly popular due to aggressive marketing by the MBTI-trust and their trainers. So most people are very pleased with the results. The test results are delivered in an elaborate document containing a very recognizable description of your personality type. The test-taker is categorized in 1 of the 16 different personality types easy to understand and easy explain. MBTI offers 45 minutes to “accurately” determine someone’s personality. MBTI is popular because it is simple to explain, easy to execute and takes limited time. You should never participate in an MBTI test, unless you have determined the exact outcome you want to achieve. The testing method is not scientifically proven and very commercial driven. The results of the test are questionable and can be influenced by focussing on a certain type upfront. Based on studies and personal experience, it is my opinion that MBTI is an inadequate tool for determining career path and/or promotion in the workplace.

Mainly to satisfy my interest in this field and as a required entrance level for a management training. Over The past few years I have taken this test a couple of times (obligatorily and voluntarily).

I have also researched a lot of the studies critical to MBTI and found the discussion about the validity of MBTI very interesting. Many careers have been made (or halted ) by the MBTI test, that is exclusively distributed by California-based CPP Inc.ĭuring my university education, I learned about MBTI and fantasized about being able to accurately determine a personality within 45 minutes of testing and projecting someone’s career path based on these test results. The test is being used for selecting, replacing staff and to validate candidates for promotions. The Myers-Briggs Type Indicator ( MBTI) is the most popular diagnostic self-test offered to identify personality type.
