Is the neuroscience behind MBTI legitimate


Why do experts have problems with the MBTI? One reason for this is that while the Myers-Briggs classify people differently, scientific evidence suggests that personalities don't exactly fit into 16 boxes.

Traits are looked at more closely, not as categorical dichotomies -extroverted or an introvert, thinker or feeler - but as continuous dimensions: for each trait an individual can rate relatively high, low, or somewhere in the middle, and most people fall in the middle. Personality tests preferred by scientists, like the Big Five Inventory, don't describe each personality in categorical terms, but rather based on how high or low a person scores on each of the five (or six) non-overlapping traits.

The type-based feedback from the MBTI is also not particularly consistent. A person who takes the test twice can easily be given two different type designations. In addition, the MBTI leaves out real aspects of personality that have negative connotations, such as neuroticism (emotional instability) or facets of low conscientiousness. However, it is not true that the MBTI does not measure anything at all. Research suggests that when MBTI preferences are rated as continuous dimensions rather than categorized, there is some correlation with ratings of the Big Five traits.
