What is your character’s personality type?

In my previous post, I suggested that the use of psychological typologies is a useful starting point for character creation or when you’re stuck in their development.
Today, we will have a closer look at the Myers-Briggs personality test (MBTI).

Personality tests are controversial to some people. Recently, I talked to a friend of mine about the MBTI. He questioned whether it is pseudoscience like horoscopes.
Or worse, like a Buzzfeed quiz about which Game of Thrones character you are.
(They are fun though, who are you? 😉 )

Not quite. 

The MBTI is based on Carl Gustav Jung’s extensive research around what he called the ‘self’. His work suggests there are different parts of ourselves. The Self, representative of your inside world, and a persona we put on for the outside world. Test your Self and Persona here.

No one is going to match a personality type 100%. Results depend on mood, experiences and concentration. Instead, they give us an impression or a tendency.

In character development, personality types give us an overview of a character who starts out on his journey. Who will he be at the end of it? That depends on what you put him through and whether you want his weaknesses to become heightened or to turn into his strengths. Being aware of your characters’ flaws and strong points will make it easier to decide how they respond to various problems.

Problems like what?

Applied to fictional characters, tests like the MBTI can help us with a range of questions, such as:

How would a character approach a relationship problem? Would he openly talk about the issue with his significant other or dwell in silence until the small problem gets blown out of proportion?

How does your character act as a mom or dad? Does he play the good or bad cop when the little ones spread peanut butter all over mom’s new clothes?

Would the young woman in your story be able to manage a business, shoulder the responsibility with a charismatic smile, or would she buckle under the pressure?

Examples of Types in Practice

ENTJ – Grumpy business owner

In one of my short stories, there is a business owner who could be identified as an ENTJ. He is ruthless and sickeningly confident to the point that he scares off everyone around him. His attitude problem lands him in troubled waters with his community. No one bothers to stand up for him. He is forced to either trust someone he doesn’t know or drown.

ISFJ – Soul of a community

In the same short story, there is a young community leader. Her innate need to protect the people of her hometown makes her go up against the grumpy business owner. While she teaches him to become more patient with other people, he reprimands her for taking on the burden of an entire community without regard for her own health. Their contrasting personalities actually help the other grow.

ISFP – Crazy auntie

This character type is one of my favourites to write. My crazy auntie character excels in life by pushing the social boundaries and embracing her status as a free-spirit who drinks too much wine during boring family dinners. Her open-mindedness and ability to make everyone feel welcome is a basis for a much-loved character. However, her over-reliance on herself and hatred of everything ‘conventional’ causes her to keep serious health issues a secret.

You have the basis of your character. What now?  

Now comes the point where I tell you these personality types are archetypes, not real people. No one is 100% ISFP or 100% platinum blonde (congrats if you are!).

Traumatic events or challenges will force characters to face their core values and re-establish their personalities. Villains and antagonists will shatter the protagonist’s world view.

Your character may start out as a controlling ENTJ but, over time, and through many obstacles, he might learn that his focus on himself is hindering him from making true human connections. He will have to learn to trust people and respect their feelings. To make your characters progress, they will have to confront their weaknesses and deepest, gut-wrenching fears.

It takes time to create the perfect concoction of personality types, quirks and magic to make your character a three-dimensional person on the page.

If you have a soft-spoken, timid INFJ who is faced by a big, bad monster, she will need to step up to protect those around her. She might take on leadership qualities that have been dormant inside of her but never dared tap into.

Give your readers the chance to follow her journey of self-discovery so they, too, can evolve and grow in their own lives.

Putting characters into boxes

Sorting people into boxes or categories is not something I would usually encourage, but there can be an exception made if you are a writer who is looking for a starting point in character creation.

Most of the time, you won’t sit at your desk and think up a character. The best main characters just appear, materialise out of thin air and take over your brain. If you try to ignore them, they’ll flip you off or stomp their feet. Scribble down those quirks and mannerisms for later.

In the early stages of character creation, I like to analyse what personality the materialised gal or guy (or alien, animal, tree…whatever floats your boat) might have. For example, for my current protagonist, I knew right away that she was an INFJ from the Myers-Briggs Type Indicator. INFJ is also called the Advocate personality. In my story, she is an idealistic young lady, slightly neurotic and secretive, but with genuine care for her people. Her sense of morality, however, makes her life incredibly complicated in the face of her corrupt family.

Your characters will evolve and grow throughout your story. They might become completely different people with new tendencies and ideals, or they will become their own worst nightmare. Either way, you need a foundation before you can start building. Look at it like a skeleton that gives your character the ability to stand. Add tendons and muscles through physical features, quirks and mannerisms. Finally, never forget the flaws that make your heroes and villains human and relatable.

Not every character needs to be loved and admired, but even the bad guys have a reason for what they are doing. Often their motive stems from an even more intense feeling or ideal than that of the protagonist. It makes them such good villains in the first place. That creates a conflict that drives your plot. Be careful though too many heroic ideals can be overstimulating. The core of your character might get swept away in a creative tsunami. So decide on a foundation and stick to it. It steers your plot.

Your secondary characters will probably fulfil more archetypal roles. That’s fine! It’s not to say they won’t change at all, but there is a reason they are behind-the-scenes.

Carl Gustav Jung’s typology gives an excellent overview of 12 common personalities. Jung’s work was actually the basis from which the Myers-Briggs Test was developed. So, while your protagonist will most likely break out of his original box, as he, she or it should, your secondary characters might be happy to stay ‘the mentor’ or ‘the caregiver’ to the end. This will help you keep focused on your main characters without being distracted by extensive character development at all levels. No one can keep up with a cast of twenty people that all go through different crises.

Over the next few weeks, I will look at some of these typologies more closely. For now, have a scroll through the ones listed below to get you started. If you haven’t done so, I’d recommend doing some tests yourself. The better you understand yourself, the easier it will be to understand others, including your own characters.
