It’s hard to answer that concisely but one way to answer it concisely might be: mbti are often described as personality types, “The INFP tends to like x and often does y, they dislike z, …” the big five are just five arbitrary dimensions arrived at through factor analysis, they are descriptive more than predictive, they were not developed by Jung, a personality theorist. My point is that the things we can easily measure are not what we think of as personality. Your wife, daughter, dog, are not reducible to the big five. Whatever the extra stuff is, beyond those five dimensions, that’s specific to individuals and persistent, what we call a personality, is a very real thing that cannot be demonstrated empirically. That should humble us to the limits of our ability to understand the human mind, and complicated human mental processes like learning.
