16 Personality Types – Star Trek Style

In Jeff Gerke’s book,  Write Your Novel in a Month – How to Complete a First Draft in 30 Days and What to Do Next there was a chapter on creating characters. Gerke suggested making use of the Myers-Briggs Personality System. For those of you who are not familiar with it, you can read more about it here

Basically the Myers-Briggs system categorizes personality types into sixteen categories based on these four basic preferences.

Introversion (I) versus Extorversion (E)

Intuition (N) versus Sensing (S)

Feeling (F) versus Thinking (T)

Judging (J) versus Perceiving (P) – I still have a bit of trouble understanding the difference between these two, but basically I look at it this way. Judging types tend to like everything tied up nice and neat in a smart little bow. Perceiving folks are more likely to let things hang a bit more loosely.

By determining which of the four pairs a person prefers, you can come up with sixteen personality types. I use this a lot when I’m creating characters. To make the system easier for me to remember, I associated each of the sixteen types with characters from all four incarnations of Star Trek. These are my personal opinions so you might not agree with my selections, but that what’s fun and flexible about the system.

The description of the sixteen types are from Gerke’s book and from here.

As I said, these are just my opinions and you may or may not agree with my classifications, but I set this up mainly as a quick snapshot of each of the personality types so that when I’m “casting”  my fiction, I may say I want to make a particular character more of a Neelix type than a Spock type. I also like to pair characters that are diametrically opposed in personality.

This was done a lot in Star Trek. For example, there were the epic battles between Mr. Spock (ISTJ) and Dr. McCoy (ESFJ). Although Spock and McCoy both favor using their senses over intuition (they both share an S), which makes sense in that Spock is a scientist and McCoy is a doctor and both tend to make evaluations about the world based on their senses, Mr. Spock is a thinking introvert and Dr. McCoy is a feeling extrovert, which led to quite a few disagreements on a number of topics.

In Star Trek:Voyager, Neelix, who is an ESFP,  was paired with Commander Tuvok, who  was another ISTJ like Mr. Spock. In this case, the two characters were pretty much opposite on all the traits except for one. So usually whenever Neelix was around Mr. Vulcan, as he called Tuvok, Neelix usually got on the sotic Vulcan’s last Vulcan nerve with his extroverted, emotionally driven exuberance for life.

  1. Oh, I love this idea! Of course I’m familiar with the Myers-Briggs but I’d never thought to apply them to well characters as a guide. Awesome. Thanks for sharing your take on the types.
