Dr. Jennifer Keller’s MBTI has become a point of interest among fans of Stargate Atlantis, thanks to her emotional openness, quick thinking under pressure, and relatable vulnerability. Played by Jewel Staite, as a physician in a high-risk environment, Keller displays strong traits of an ENFP Enneagram 6w7, often called “The Loyal Skeptic.” Her combination of empathy, anxiety, and adaptability makes her a compelling example of a personality type driven by both care for others and a need to anticipate what could go wrong.

Extraverted Intuition

Jennifer is the first one on the Atlantis team after Dr. Weir leaves to form connections or theories which later prove accurate (after an outbreak of nightmares in Atlantis, she realizes since the villain is always John Sheppard, he must be the source of the infection; when the team bring back crystals to study them, she tells them the crystals are dangerous, with a mesmerizing ability, and should not remain in the city; when Teyla believes her people have been eradicated, Jennifer tells her not to lose hope, and is later vindicated when they find them alive, but prisoners). She also sees potential in Rodney, because she can tell what he “could” be, beneath the autistic-coded narcissistic jerk, and because of her influence, he has a personal growth arc and is able to overcome some of his less-desirable traits. She is optimistic and finds it easy to switch gears, change theories, and focus on new medical approaches, without much warning or preparation.
This is what Ne does well—it brings in new ideas and changes direction on the fly, by working through problems on the spot (one of the best examples of her doing this is in the episode when she, Sam, and Rodney are stranded in an underground mine, and she proposes using that “stupid game you use to win free beer” to build a way to reach the hole in the roof; it doesn’t work, but she still came up with a creative solution by thinking of an unrelated problem and using it as a catalyst).
Introverted Feeling
She is visibly unsettled by human experiments and what is being done to them by Michael, and doesn’t frame her arguments against these things as violating procedure, but by saying “this isn’t right.” She responds to her patients and everyone she meets as an individual, and personalizes her care to each one (by talking to the patient, not just treating them). Her concern is their suffering, so she asks what she needs to do to help them. Under pressure, she evaluates situations through assessing her own capabilities (can I do this? Is this right for me? What if I make a mistake?). All this “I” referencing is how Fi navigates the world; it sees things from an inside-out perspective, starting with “me” and “what I can do.” She also opens up more with specific people, rather than with everyone; once she becomes friends with and then girlfriends with Rodney, she is more candid, responsive, expressive, and comforting. And when he won’t take a hint, she asks him straight out, “Do you want to have a drink with me or not?”
Extraverted Thinking
Jennifer is good at assessing the limits of the situation, or bluntly stating the facts or problems with someone else’s reasoning. When Rodney, exhausted from lowering two people on a rope to an underground mine shaft, stops moving, instead of cheering him on, Jennifer says, “That’s it? You’re just going to give up and hang there forever? That’s your solution?” Te tends to be blunt rather than persuasive, but this tactic usually forces Rodney into action again. Her approach is to problem-solve, using the most obvious methods first (to innovate using oxygen tanks to break down a locked door, for example), but when that doesn’t work, Jennifer becomes “stuck.” She trusts Rodney to get them out of trouble more than she relies on her own logic; yet, she’s good at backing up her statements with facts, explaining medical data, and working within time constraints. She wants to get things done, and has no trouble running the medical bay, making tough calls (quarantining people, even if they don’t like it) or stepping down when she believes herself compromised.
Introverted Sensing
This is where her limitations and self-doubt kicks in the most; she’s frequently out of her depth in sensory situations. When she and Teyla are stranded on a planet overrun with criminals, Jennifer is terrified to cross a river on a thin rope ladder, fails at defending herself physically, is intimidated to eat a dead, raw animal (even if Teyla says it’s fine), etc. She manages to do all those things, but her sensory-inhibitions make it scary and difficult for her (inferior Si).
The Enneagram 6

6s assume that other people are better in positions of authority than they are and don’t want the responsibility in case they make a mistake. Jennifer shows this kind of thinking throughout her two seasons; she is cautious, she asks if anyone else could take Dr. Beckett’s place (instead of her), she turns down promotions, and she says out loud, “I can’t do this” many times. Fear drives her to assume Teyla would be better off without her, but the fear of being alone forces her to cross a rope bridge that terrifies her (“I am not so good with heights”). But she also has the 6’s warm tendency to champion other people, encourage them, work with them even if she dislikes them, and to tell them to tone down their reactive negativity or insults (she tells Rodney he doesn’t have to be defensive or insecure). 6s are loyal, and once she falls for Rodney, she stands by him even when his behavior aint’ great.
The 7 Wing
Rather than withdraw in times of stress, Jennifer opens up to other people, inviting their comments, ideas, and even criticisms, showing her attachment to them. (6w7s are less self-reliant than 6w5s.) She also came to Atlantis despite being cautious and fearful because she wanted an adventure—and at the end of the day, after a stressful situation has subsided, she wants to have a good time; to go out with her friends, to tell funny stories, to crack jokes, and to make light of the situation. Even though she’s afraid a lot of the time, Jennifer will optimistically encourage other people to think on the bright side and assume, somehow, that things will turn out all right, and often she’s correct. This is the “delusional positivity” of the 7 wing, keeping a 6 on track through dangerous times.
