Clue MBTI: The Thinking Functions


Colonel Mustard: Extraverted Thinking (Te)

Col. Mustard organizes everyone into search parties and tries to get control of a chaotic situation. He’s a military man who wants to do things by a strict, military standard, especially when everyone else is freaking out. He understands that if they split into pairs, one of them might be paired with the killer and thus get killed themselves, but it seems like a simple way to find out who the killer is. This is war, after all, and they have to win despite the risk of casualties. He directs the piling of the corpses on the sofas, pointing out the optimal way to get them to fit when the others struggle to position them properly. He demands straight answers from Wadsworth about who is in the house, and gets frustrated with the complicated replies.

Best Suggestion: ESTJ


Professor Plum: Introverted Thinking (Ti)

Professor Plum analyzes people for a living, and tends to reduce them to a series of logical principles. After Mrs. Peacock rambles on at dinner, he picks apart her behavior and diagnoses her with a form of insecurity. When the others are trying to figure out which of the weapons they were given was used to kill Mr. Boddy, Plum reasons that it might have been something else entirely—poison! In the “real” ending, Plum is the one who kills Mr. Boddy (who’s actually Mr. Boddy’s butler posing as Mr. Boddy; it’s complicated), but his plan is needlessly complex, first faking Boddy’s death and then sneaking back when no one is looking to kill him for real a second time.

Best Suggestion: INTP


ENFJ: Dukat, “Star Trek: Deep Space Nine”


ENFJ – the Giver, the Mentor, the Believer

I’ve no idea if it says anything about the franchise that the biggest nemeses in two different Star Treks are ENFJs. Even TNG had Lore, the ENFJ cult leader. Seems like Star Trek may have a running theme about the dangers of following crazed, charismatic leaders with big but empty promises.

(P.S. I feel really gross using my cheesy terms like “Believer” and “The Garden Fountain” for someone like Dukat, but that’s the format.)

Dominant Function: (Fe) Extraverted Feeling, “The Garden Fountain”


Gul Dukat needs to be loved. We all do, of course. Dukat, however, lives and breathes off the adoration, honor, praise, and hero-worship of others—which he never gets.

Back when he was made Prefect of Bajor during the Occupation, Dukat believed a gentler approach was needed. He enacted policies to ease the burden on labor camp workers, but strangely, the Bajorans failed to show appreciation for his compassion. They seemed to dislike being occupied by an invading force no matter how nice he was about it. They continued to resist him, and Dukat felt compelled to strike back and punish their ingratitude.

This cycle describes much of Dukat’s life and career. He wants to lead, but when his subjects or fellow leaders don’t like him, he struggles. He either overcompensates and looks desperate, or lashes out and becomes the angry tyrant he claims not to be. Continue reading

INFJ: Weyoun, “Star Trek: Deep Space Nine”


INFJ – the Counselor, the Seer, the Defender

Wait, haven’t we seen this guy before? No, it’s not because Weyoun is a clone, it’s because Jeffrey Combs played another DS9 villain, Brunt. They even appeared in the same episode once, though sadly, not in the same scene.

Two Weyouns once appeared in the same episode, too, because the character we know as Weyoun is actually a series of clones (Weyouns 4-8 during the run of DS9, to be specific). However, because he’s genetically engineered to do his job perfectly, he always has the same personality, even when he turns out “defective.” In MBTI, your type is generally a function of nature rather than nurture—you are wired the way you’re wired no matter what, though personal experience will influence how your functions manifest. In Weyoun’s case, his “nature” is embedded in his DNA by those who “nurture” him, the Founders he reveres as gods.

Dominant Function: (Ni) Introverted Intuition, “The Labyrinth”


Weyoun believes in the mythos of the Dominion—that the Founders are gods who bring order to the galaxy. He believes that the Dominion will endure for thousands of years after the Federation is gone, and works to advance their holdings and influence with every move he makes. He believes that his goals are divinely inspired by the Founders, perfect and not to be questioned.

Even the defective Weyoun 6 still holds the Founders in awe and reverence, even though he awakens from the cloning process with the inexplicable idea that the Dominion’s war efforts are wrong. Continue reading

ESFJ: Winn Adami, “Star Trek: Deep Space Nine”


ESFJ – the Provider, the Facilitator, the Caretaker

A smiling, self-righteous old lady enters the place our family of misfit characters calls home and immediately sets everyone on edge with her overbearing rules and conspiratorial grabs for power.

Nope, we’re not profiling Dolores Umbridge today. It’s Star Trek’s own Space Pope, the chillingly wicked Kai Winn. DS9 has some truly lovely Fe-doms on board, but Winn brings the Mean Girl-ness to a religious level.

Dominant Function: (Fe) Extraverted Feeling, “The Garden Fountain”


When Winn Adami first saw the wormhole—or the Gates of the Celestial Temple, as her people believe them to be—she felt nothing. All her fellow Bajorans around her, however, reacted in awe, and Winn felt she had to display the proper response. She never has a personal experience with the Prophets her entire life, but rather loops through her Fe-Ne, playing along with the Bajoran faith to pretend that she believes what everyone else believes.

Her rise to power is driven by her need to be seen as more righteous than others despite her insecurities. She finds it deeply distasteful that the Prophets chose an outsider like Sisko as their Emissary. She can’t even get out of his shadow after she ascends to Bajor’s highest religious position. Winn speaks sweetly even to her enemies—perhaps more so—and passive-aggressively insults those she dislikes, always acting shocked when someone (usually Kira) calls out her true motives. Continue reading

ESFJ: Leeta, “Star Trek: Deep Space Nine”


ESFJ – the Provider, the Facilitator, the Caretaker

Like Kira, Leeta’s a young Bajoran woman who survived the Occupation. While one of them picked up a gun, the other picked up some Dabo skills. Kira’s Fi-dom makes her edgy and angry, while Leeta moves through the world with an Fe-dom’s openness and generosity, making her living as the life of the party in the hub of DS9’s communal bazaar.

They both fall for some pretty weird Introverted dudes, though.

Dominant Function: (Fe) Extraverted Feeling, “The Garden Fountain”


Like her ESFJ boss, Leeta’s gift is hospitality. She entertains guests every day at Quark’s Bar, coaxing their energy up to keep the room lively. Her job is to make sure everyone is happy, enthusiastic, and spending money. She’s something of an amateur sociologist, which comes in handy considering all the diverse people she meets in her line of work.

Leeta’s a very skilled people-person, and quick to make friends. She’s barely known Jadzia for more than a few weeks (like, one episode) before Dax invites her to participate in the very intimate ceremony of sharing a consciousness with one of her past hosts. She coyly flirts with Julian, feigning illness to get his attention; and when it’s time to break up, she finds an amicable way to do it that ensures no hard feelings. Continue reading

ESFJ: Joseph Sisko, “Star Trek: Deep Space Nine”


ESFJ – the Provider, the Facilitator, the Caretaker

Ben Sisko’s two biggest nemeses are Fe-doms (more on that during DS9 Villains Week), so it only seems balanced that one of his strongest guardians is an Fe-dom as well. Brock Peters had already appeared in the Star Trek universe during the original cast years as Admiral Cartwright, so I like to think that the Siskos are his descendants. Cartwright didn’t turn out so good, so he’s lucky he has men like Joseph down the line to make sure Earth is still a happy—and delicious—place to live.

Dominant Function: (Fe) Extraverted Feeling, “The Garden Fountain”


Joseph makes an outgoing host at his restaurant, cooking up a storm for his guests, welcoming them in and checking up on them as they eat. He recommends desserts and won’t let them say no. He even intends on serving the Starfleet officers patrolling the streets, despite the fact that he disagrees with their reasons for being there—they’re going to need a meal at some point, after all.

As much as Joseph fusses over his family and guests, he hates being fussed over in return. He denies to his son Ben that he feels ill at all, and doesn’t want to slow down or leave the restaurant in the hands of anyone else. He’s eager for his son and grandson to join him when they return to Earth, and doesn’t quite understand that Ben’s visit is for work, not pleasure. He acts a little dramatically hurt when they don’t stick around long enough for his liking. Continue reading

INTP: Rom, “Star Trek: Deep Space Nine”


INTP – the Architect, the Thinker, the Philosopher

The Ferengi are an ambitious bunch, and all but Rom in this series are Extraverted Judgers. Rom stands alone among his kind as an Introverted Thinker, always out of step with the rest of his people’s hustle. In fact, his functional stack is exactly the opposite of his brother Quark, the ESFJ. So it makes sense that the two siblings clash and annoy each other so perfectly.

(Rom goes through a big character change after his first few appearances. He starts out like a standard, greedy, duplicitous Ferengi, but too stupid to succeed without his brother. Then we suddenly begin to see his sweeter side, and he goes from humble, underpaid waiter, to engineering genius, to Grand Nagus of a reformed Ferengi Alliance. Unlike Dax, he doesn’t have a symbiont to blame this transition on, but after careful observation, I think it’s safe to say that early, evil Rom is still an INTP.)

Dominant Function: (Ti) Introverted Thinking, “The Laboratory”


Rom doesn’t seem at all bright when he’s first introduced. Quark accuses him of not being able to fix a bent straw, and calls him “my idiot brother” as often as he calls him by name. He appears constantly baffled, confused, and unable to follow instructions.

Secretly, Rom’s an engineering genius. His son Nog knows this about him and despairs of his father ever getting the opportunity to succeed the way he should. Rom’s brain simply doesn’t track with the rest of the world around him, especially the Ferengi world, so he looks like he’s always behind. Continue reading
