Whether or not your personality type can change is quite a point of debate in the Myers-Briggs® community. Officially, Myers-Briggs® theory holds that your personality type is inborn and does not change. In other words, you cannot start out as an ISFP and then transform into an ESFJ (or any other types) over the course of your life.

Practically, though, we know that people take personality tests all the time and get different results. It’s one of the big arguments leveled against Myers-Briggs® theory — that the tests don’t deliver consistent results and are therefore not valid, repeatable, or scientific. On top of all that, you might have seen articles about new research over the last few years that indicates your personality can change over your lifetime. How do we make sense of all that in relation to type theory?

Personality Traits vs. Personality Type

On the surface, it seems that Myers-Briggs® disagrees with psychology studies that say personality can and does change. But when you take a closer look, you’ll see there’s not really a disconnect. There’s a big difference between personality traits and personality type. The personality model that most psychologists favor today is called Big Five. It includes five key traits — extroversion, agreeableness, neuroticism, contentiousness, and openness.

Where you fall on these traits can change, though they’re considered relatively stable. When change happens it tends to do so gradually over many years (change is more likely and more rapid when something significantly life-changing occurs, such as  a traumatic experience) . We also tend to be more stable in some traits and less stable in others. You can read more about this in the following articles: Read more →
