The Myers-Briggs Type Indicator is one of the most popular personality tests in the world. The companys website boasts the assessment has a 90% accuracy rating and a 90% average test-retest correlation, “making it one of the most reliable and accurate personality assessments available.”
What is the main purpose of taking the Myers-Briggs test?
The MBTI® assessment was designed to help people understand personality differences in the general population. While there are no “better” or “worse” personality preferences, the MBTI assessment can help people understand their strengths and blind spots and how they might differ from others.
Why is MBTI unreliable?
Some research suggests the MBTI is unreliable because the same person can get different results when retaking the test. This is a shortcoming, because people dont fall neatly into two categories on any personality dimension; instead, people have many different degrees of the dimension, Ashton told Live Science.
