Years ago I discovered the Myers-Briggs Type Indicator (MBTI for short). One of the things I really liked about it was seeing the kind of people or fictional characters I shared traits with. Classifying book characters by their Myers-Briggs type is very fun! But for those of you who don’t know what MBTI is, let’s backtrack a little. The Myers-Briggs Type is a theory that aims to categorize psychological types by how a person perceives and reacts to the world. It uses four letters or categories to do so, and it can give you one of 16 different combinations. That’s what you call a “personality type.”

These letters are: E for extrovert, I for intuitive, S for sensing, N for intuitive, T for thinking, F for feeling, J for judging, and P for perceiving. You then combine those letters or categories to form the types. For example, I would be an INFP. You can read more about it on their website, or look for a book about personality types. But that’s the gist of it, and today I’m here to have fun with the personality types. Related to bookish things, this means I’m here to share with you which Myers-Briggs type are our favorite book characters!

One last thing before we start. I’ll be talking about 150 MORE fictional book characters by their Myers-Briggs Type. For we already have a list with no less than 202 characters! So strap in and let’s get started.

INFJ – The Counselor

Creative • Observer • Avoidant • Cautious • Private

INTPs are detached, philosophical, innovative, and analytical observers.

ESTJ – The Supervisor

Organized • Group-Oriented • Focused • Conventional • Leader

They are assertive, logical, and quick-witted — and their driving force is their need to analyze and bring order to their outer worlds.
