"Will my personality type change over time?"

This is a question I have been asked hundreds of times in the last 29 years of working with personality type in the quick answer is no; that is also the honest answer, although at times one may feel their type has changed.

The reason for feeling like your personality type may have changed is because you have in all likelihood been exposed to use in your non-preferred behaviors quite a bit. This could be because you're working in a job that requires you to use non-preferred behaviors in order to get the job done more rather than less, or you been exposed to some kind of environment and do not have the opportunity to use your preferred behaviors.

Remember personality type is instinctive. In other words while you were's literally being formed in the womb of your mother you were imprinted to prefer certain behaviors over others; however, you will and should use all behaviors.

So, it can be reassuring to know that once you know which of the 16 personality types you are, you will be that type for the rest of your life. It may also be reassuring to know that you will use hundreds of behaviors you do not prefer and that is not necessarily a bad thing unless you use them too much.
