A daydreamer and a bit of a lost cause, Rey loves stories. Whether they're book shaped or you can see them on a screen, a story always hides in the corners of her mind. She's working on a few stories of her own, always accompanied by her trusty cat.

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 

INFJs are creative, dedicated, and intuitive. But they are also private. So while they might be good at reading others’ emotions, they rarely share their own. This type also tends to look inwards, cherishing human development, spirituality, and their own creative expression.

INTJ – The Mastermind

Loner • Observer • Perfectionist • Private • Skeptical

Loner • Disorganized • Observer • Private • Detached

INTPs are detached, philosophical, innovative, and analytical observers. They spend a lot of time inside their heads, trying to understand how things work — especially concerning the mysteries of the universe. Therefore, they’re naturally curious, even if they don’t seek to control the outer world.

Content • Self-Confident • Outgoing • Open • Decisive

ESTJ – The Supervisor

Organized • Group-Oriented • Focused • Conventional • Leader

There’s a reason they call ESTJs the supervisors, for they are more traditional leaders who love organizing projects and people. They are also quick to complete tasks and love to do things “by the book” because of their analytical, logical, and pragmatic nature.

ESFP – The Performer

Outgoing • Conventional • Talkative • Spontaneous • Emotional

If one thing defines ESFPs, it’s their contagious enthusiasm for life. They are always warm, talkative, playful, and charming — and love to engage with their surroundings. Especially people. This type prefers experiencing life as is, rather than judging or organizing it.

ENTJ – The Fieldmarshal

Decisive • Planner • Engaged • Ambitious • Dominant

ENTJs are commanders, strategic leaders who love making long-term plans to fulfill their vision. They are assertive, logical, and quick-witted — and their driving force is their need to analyze and bring order to their outer worlds.
