The Myers-Briggs Type Indicator (MBTI) allows people to find more about their personalities, likes, dislikes, strengths, weaknesses, or compatibility with other people. It first began with Katharine Cook Briggs and her daughter Isabel Briggs Myers in the early-mid-20th century. Briggs was inspired by her husband's personality type theory study. World War II also had a significant impact on the project's creation, and Myers believed that if people could understand each other better, they would be able to work together more effectively. She spent 20 years developing the MBTI instrument to provide people access to their psychological type.

 

The MBTI test identifies people as one of the 16 personality types. In the MBTI test, people have to answer a list of questions and when they are finished, the results are then interpreted and categorized as one of the 16 personality types. Now, the MBTI test is a popular test that allows people to easily find out about their psychological preferences in how they perceive the world and make decisions. However, there are diverse opinions on the accuracy and reliability of this test. 

 

Some psychologists believe labels like ENTJ or ISFP are all meaningless and people shouldn't rely on the results. For example, Adam Grant, an organizational psychologist at the University of Pennsylvania says, "there's just no evidence behind” this MBTI test. He questions how the characteristics measured by the test can predict how you will react or act in different situations. Since the MBTI test was developed in the 1940s based on the untested theories of Carl Jung, it makes it more unreliable. During that time, Jung even warned that the personality "types" were just rough tendencies he'd observed, rather than strict classifications. However, others argue that people can be accurately categorized into one of the 16 personality types as long as they are being completely honest and self-reflective with their answers while taking the test. 

 

The accuracy of the MBTI test is still argued by many experts. Although this test can’t be completely accurate for categorizing everyone in the 16 different personality types, if this test is used for self-reflection or a starter for discussing how people have different personalities, and perspectives, it can be a useful tool to resolve conflicts and change the world for the better.
