Research has since found that upwards of 50% of people got a different score when they re-took the MBTI just five weeks later. Studies have also shown that the test is not effective at predicting people's success in different jobs. -USAToday
Research has found that as many as 50 percent of people arrive at a different result the second time they take a test, even if it's just five weeks later. That's because the traits it aims to measure aren't the ones that are consistently different among people. -Vox
Psychologists' main problem with the MBTI is the science behind it, or lack thereof. In 1991, a National Academy of Sciences committee reviewed data from MBTI research and noted "the troublesome discrepancy between research results (a lack of proven worth) and popularity."
The MBTI was born of ideas proposed before psychology was an empirical science; those ideas were not tested before the tool became a commercial product. But modern psychologists demand that a personality test pass certain criteria to be trusted. "In social science, we use four standards: Are the categories reliable, valid, independent and comprehensive?" Adam Grant, University of Pennsylvania professor of psychology, wrote on LinkedIn.
