Clue MBTI: The Sensing Functions


Miss Scarlet: Extraverted Sensing (Se)

Miss Scarlet’s the least panicky and frightened of any in the group (at least at first), unintimidated by her eerie surroundings and seemingly eager to see what plays out. She uses her sultry good looks to her advantage—when her car breaks down on the way up to the mansion, she shows a little leg to an oncoming car and hitches a ride. She isn’t shy at all about her line of work, and when everyone else is protesting their innocence, she proudly owns up to running an escort service. She sees nothing wrong in profiting from the world’s oldest profession, catering to the very natural needs all men have. She’s smart and capable, but sometimes misses the point of the absurd wordplay in conversation (“Why would he want to kill you in public?”).

Best Suggestion: ESFP


Yvette: Introverted Sensing (Si)

I hate to use the servant as the example of Si, but bear with me here. Yvette is a stand-in for the many trusty stewards in old-fashioned murder mysteries, knowledgeable and competent and attentive to detail. They’re studied experts at various handy skills. They’re the ones who have been around forever and know every nook and cranny of their home. They know its history, too, and all the good, juicy stories about the locals. Yvette gathers information for her employers (both Mr. Boddy and Miss Scarlet), and she’s trusted to execute the careful steps of Wadsworth’s plot. She tends to the order of the house, and has a great deal of seasoned experience in her, um, profession. She’s afraid of the dark, and grows more anxious and terrified as the evening spirals beyond the expected plan.

Best Suggestion: ISFJ


ESTJ: The Founder, “Star Trek: Deep Space Nine”


ESTJ – the Director, the Achiever, the Optimizer

When we type a villain, we usually expect their inferior function to be their fatal weakness. For Te-doms, the stereotype is that they have no moral oversight to their actions. By contrast, the intimidating Founder has a very clear moral vision–she believes she is absolutely entitled to wield control over other, lesser species.

Another of DS9’s ESTJ villains, the meddling Brunt, acts the same way. He enforces the laws of Ferengi society with an aggressive sense of justice. Just like a weak inferior-Te user might use faulty logic to defend their subjective beliefs, inferior-Fi can provide the comfort of self-righteousness to an over-controlling ExTJ.

(This character was never given a name on the show. Instead, she was referred to in dialogue and in the credits as simply, “Female Changeling.” That’s super clunky and annoying to type over and over, so for simplicity’s sake, I’m just calling her “The Founder.”)

Dominant Function: (Te) Extraverted Thinking, “The Workshop”


The Founder’s major directive is to bring every civilization she meets under the control of the Dominion. She sees it as her calling to bring order to a galaxy racked with chaos. Solids, she believes, don’t know enough to govern themselves, and so the Founders must lead.

The Founders exert control over their realm through their minions, the loyal Vorta and Jem’Hadar. Both races are genetically engineered to be obedient without question, and to view the Founders as gods. For further control, the Jem’Hadar are engineered to be addicted to a drug called Ketracel-white, which only their “gods” provide. Continue reading

ISTJ: Michael Eddington, “Star Trek: Deep Space Nine”


ISTJ – the Inspector, the Sentinel, the Expert

Eddington undergoes a major character switch when he becomes a villain. After a couple of years serving quietly in the background, he jumps ship (or station, as it were), and goes rogue. He’s more aggressive and dramatic as a crusading Maquis than he was as a law-abiding Starfleet officer, leading me to believe he’s operating out of his lower functions when he makes the change. Eddington sees himself as the hero of his own story, but to Starfleet and Sisko, he’s a terrorist.

Dominant Function: (Si) Introverted Sensing, “The Study”


At first, Eddington seems like a good old-fashioned, reliable Starfleet officer. He joined with the ambition of being a captain, like everyone else, but ended up in security. That department doesn’t typically lead to command, but he still stuck to his job and did it well. Sisko asks him why he doesn’t just transfer over to the command division, but Eddington doesn’t seem interested in a big change at this point.

Of course, that could just be because he has other things brewing.

Eddington eventually reveals himself as a leader in the Maquis, a terrorist group dedicated to protecting Federation colonists left behind in Cardassian territory after new borders are drawn. The Maquis, and Eddington, don’t believe they should have to leave their homes for any reason. Though they’re offered many alternatives, they hold their ground and refuse to leave no matter how poor their living conditions grow.

Eddington appreciates the real, hand-grown, fresh food he raises and eats as a Maquis. He doesn’t like the taste of replicated food, and recognizes the exact menu selection he’s given as a prisoner. His whole existence as a Maquis feels more natural to him than his outward presentation as a Starfleet officer. 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

INFP: Keiko Ishikawa-O’Brien, “Star Trek: TNG/Deep Space Nine”


INFP – the Healer, the Dreamer, the Clarifier

Keiko O’Brien put up with a lot, and never really got her due. She joined the crew way back in TNG, then left her career to cross over with her husband Miles to DS9, highlighting the show’s themes of family life and diversity. Once the focus shifted to the O’Brien-Bashir bromance (which, to be clear, I think is wonderful), our intrepid botanist went neglected.

Most of her episodes catch Keiko on her bad days, bickering with her husband or worrying what to do with her life. It was tough deciding whether she was always in the grip, or just aggressively using her higher functions. When we see her on good days, she’s obviously smart, sweet, and crazy in love with an Irish engineer who’s as stubborn as she is.

Dominant Function: (Fi) Introverted Feeling, “The Deep Well”


Keiko and Miles love each other deeply in a way that’s obvious to everyone, but also a little inexplicable given how often they seem to be at odds. They clash in the hard-headed way of two Fi-users exasperated with constant compromise. His Fi is lower, so he has trouble working out how to emotionally respond, while her higher Fi wants to be understood without having to explain itself (as an INFP who has dated two ISTJs, I can assure you this never happens in real life…ahem). Continue reading

ISTJ: Martok, “Star Trek: Deep Space Nine”


ISTJ – the Inspector, the Sentinel, the Expert

When typing the Vulcans of The Original Series, I observed that most of them are ISTJs. The orderliness, logic, and composure commonly associated with the type just suits them. Turns out our two favorite Klingons are also Si-doms, and Worf and Martok find ways to tear apart their types’ expectations with a fury.

Dominant Function: (Si) Introverted Sensing, “The Study”


Martok has worked long and hard to get where he is. He comes from a lower-class, “commoner” background, and never forgets it. He was the first in his family to apply for officer training, but he was rejected thanks to a negative vote from the legendary Kor, who believed that those without noble blood should not be allowed in the ranks of officers. Martok holds this against Kor for the rest of his life, and refuses to speak to the man when he joins his crew for one last mission.

Martok had to work as a common day laborer due to his rejection, but he never gave up his original plan to become an officer. He served as an orderly on a Klingon warship and finally earned a field commission from his General when they fought invading Romulans. Sadly, Martok’s father had died by the time he accomplished this, and Martok carried that sore spot with him as well, nursing his grudge against Kor. 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
