Stargate | Putting SG-1 Through the Myers-Briggs Personality Test

How do Jack O’Neill, Daniel Jackson, Samantha Carter, Teal’c, and more Stargate SG-1 stars score on the Myers-Briggs Indicator Test (MBTI)?

Welcome, friend. I assume you’re here because you a) love Stargate SG-1 to little pieces and b) are obsessed with personality quizzes. But have you taken the Myers-Briggs Indicator Test? Maybe more than once, even?

If the answer to the above is a confused “hell no, what’s this Myer-Briggs thing you speak of?”, then don’t worry; we’re here to explain it to you, much as Samantha Carter (Amanda Tapping) might explain wormhole technology to Jack O’Neill (Richard Dean Anderson) and his forever furrowed brow. Hopefully in less complicated language than our favorite scientist-slash-soldier uses.

Developed by Isabel Myers and her mother, Katherine Briggs – and based on their work with Carl Jung’s theory of personality types – the MBTI test is a self-report inventory designed to identify a person’s personality type, strengths, and preferences. The result? Well, depending on how you answer the bevy of questions asked, you’ll be assigned a dominant personality quality from each of the four key categories: introversion/extraversion, sensing/intuition, thinking/feeling, judging/perceiving. This means that, yes, there are 16 unique personality types up for grabs. 

The 16 Myers-Briggs combinations from 16personalities.com.

Most people use the MBTI to learn more about themselves and what they want from life – not to mention where they excel (and fall short) at work and in social situations. Other, geekier people prefer to run their favorite TV characters through the system in order to figure out which of them they’re most like (in a pinch). Guess which of these two categories this writer falls into?

That’s right, Stargate fans; I’ve done the hard work for you and figured out where the people working hard in the underbelly of Cheyenne Mountain fall on the MBTI scale. Also, yeah, several of their off-world friends. Because let’s face it, Stargate has always been about so much more than just the core quartet.

Let’s get this party started. Or, to put it in terminology we all understand, let’s get this chevron locked.

Stargate | How We Made Stargate Infinity… and What Happened Next

The show’s creators reflect on the ill-fated animated series and reveal the studio politics that lost them the fans.

Daniel Jackson (INFP)

“The president is still uncomfortable with the phrase ‘For the common interests of the Tok’ra and the humans of Earth.’ I’m recommending ‘In pursuit of freedom for all individuals.'”

‘Divide and Conqueror’ – S4, Ep5

Daniel (Michael Shanks) is absolutely the easiest Stargate SG-1 character to run through the tried-and-tested MBTI system: he’s an INFP, through and through. 

Daniel Jackson (Michael Shanks) in ‘Maternal Instinct’ – S3, Ep20. | MGM, 2000.

Think about it; the INFP is better known on the street (if such a street exists in the world of psychology) as the “idealist” or the “mediator”, and isn’t that just our Danny boy to a tee? He’s always driven by his high values and idealistic view of the world – sometimes to the point that he winds up putting himself and the rest of the squad in danger (much to Jack’s eternal dismay; see his and Daniel’s constant squabbling if you don’t believe us). INFPs also have strong interests in making the world a better place, which – if you swap out “world” for “universe” – is Daniel’s forever MO. How else do you explain his ascension, huh?

Teal’c (ISFP)

“Undomesticated equines could not remove me.”

‘Message in a Bottle’ – S2, Ep7.

Now, Teal’s (Christopher Judge) may not strike you as a typical ISFP – largely because it’s thought of as the most artistic of the personality types – but bear with me on this one. An ISFP, after all, indicates a person who is energized by time spent alone (erm, so Kelno’reem, right?), who focuses on facts and details rather than ideas and concepts, and who makes decisions based on feelings and values – all of which sum up our bighearted Jaffa perfectly. 

Teal’c (Christoper Judge) in ‘Redemption: Part 1’ – S6, Ep1. | MGM, 2002.

ISFPs are also loyal – like, loyal AF – and so they enjoy quietly lending their support to others. Which, if you remember how Teal’c sat patiently at Jack’s side when the latter found himself pinned to a wall by a mysterious orb, couldn’t be truer of our guy. And if you want creativity – watch Teal’c in action with his staff weapon. It’s basically an elevated and deadly form of modern dance, okay?

Samantha Carter (ENTP)

“It took us 15 years and three supercomputers to MacGyver a system for the gate on Earth.”

‘Children of the Gods’ – S1, Ep1.

Samantha Carter is, without a shadow of a doubt, an ENTP. Better known to amateur psychologists as a ‘Debater’, these oh-so-Sam types tend to be bold and creative, deconstructing and rebuilding ideas with great mental agility. They pursue their goals vigorously despite any resistance they might encounter. And they’re very much “seize the day” people, grabbing on tight to the opportunities which present themselves and rolling with them to the very end.

Now, on paper Sam is your typical “nerd” character: she’s cool, level-headed, and big into facts and figures. All of this might lead some to believe she’s a shy and retiring introverted type – but nothing could be further from the truth. Because Sam is as much a warrior as she is a scientist, and a true force of nature; she’s constantly coming up with innovative solutions to problems, never afraid to speak her mind, and always willing to bend or even break the rules to see her vision through. All hail Samantha!

Sam Carter (Amanda Tapping) in ‘Seth’ – S3, Ep2. | MGM, 1999.

Jack O’Neill (ENTJ)

“You know, we really should come up with a new strategy. One that does not include us dying.”

‘Summit’ – S5, Ep15.

Jack may be one of Stargate SG-1’s funniest, most irreverent, and best-loved characters, but he’s still a born leader through and through. So, yeah, you better believe he’s an ENTJ.

Otherwise known as the ‘commander’, this personality type is a competitive, highly motivated, and focused person who sees just about everything by focusing on the bigger picture. They love planning and strategizing (something Jack is VERY good at), they prefer ideas and concepts to facts and details (which explains why he always waves away the science with an aggrieved look on his face), and they’re overwhelmingly decisive – sometimes to the point of being critical or brusque. 

Jack O’Neill enjoys some solitude in ‘Paradise Lost’ – S6, Ep15. | MGM, 2003.

What else? Well, these natural leaders are friendly, outgoing, articulate, and quick-witted to boot. Which, of all of the traits mentioned, is the most Jackish of all, right? This is, after all, the man who always has a quip or comeback up his sleeve – even in the direst of situations. Even in the Goa’uld version of Hell. God, he’s amazing. 

Janet Fraiser (INFJ)

“You can protest all you want, Colonel, but it’ll be a while before you get your strength back, so relax. Doctor’s orders.”

‘Crystal Skull’ – S3, Ep21.

She may have been killed off in one of the most upsetting TV twists of all time, but Dr. Fraiser (Teryl Rothery) lives in forever in our hearts as the true definition of an INFJ personality type.

The INFJ – aka the introverted, intuitive, feeling, and judging – personality type is characterized by gentleness, compassion, and integrity. They’re true advocates (or humanitarians, if you prefer), which means that they have a true talent for helping and nurturing others. So far, so Janet, right?

The good doctor also – like so many other INFJs – is more reserved in expressing her own opinions, and can usually be found listening attentively to someone else’s ideas or concerns. Don’t be fooled, though; she uses her counselor-like skills to help others through their issues – and she burns with a fierce intensity if anyone crosses her or calls her values into question. See, for example, every time one of her patients attempted to leave the sick bat without her permission. Or the time she point-blank refused to let anyone bully or berate her patients for information – even when that patient was Apophis himself. Or, you know, the time she literally sacrificed herself to save others in mortal danger.

Janet, you were too good for this universe and we never deserved you. Rest in peace.

Janet Fraiser (Teryl Rothery) and Sam Carter (Amanda Tapping) in ‘Rite of Passage’ – S5, Ep6. | MGM, 2001.

General Hammond (ENFJ)

“You’re all long overdue for some personal leave.”

‘The Curse’ – S4, Ep13.

Energetic, driven, and with a LOT on his plate at all times, General Hammond (Don S. Davis) is an ENFJ (better known as a ‘protagonist’). Think about it; warm, outgoing, and always tuned into the needs of others, the ENFJ is widely considered to be the strongest “people person” of all – which goes some way towards explaining how Hammond is so capable of forging friendships with all of the personality types bustling throughout Cheyenne Mountain. This is, after all, the same guy with a direct line to the president’s phone – and the same guy who met Jack and co back in the 1960s as a young soldier, took notes, and used everything he learned back then to help them some four decades later. 

Essentially, Hammond – despite appearances – is the glue that holds SG-1 together. He’s compassionate, team-oriented, and dedicated to inspiring and helping others – and he manages to keep a level head at all times, even when things are at their absolute craziest. No wonder he made general, huh?

SG-1 was just a twinkle in MGM’s iris when Bill McCay was tasked with continuing the adventures of O’Neil-with-one-L – he shares his fascinating story.

Thor (ISTJ)

“It is the opinion of the Asgard high council that Stargate Command should be left in the very capable hands of General Hammond and his team. And, while our continued friendship with Earth is not contingent on that, it is… preferred.”

‘Inauguration’ – S7, Ep20.

Look, Thor (voiced by – surprise! – Michael Shanks) is an Asgard, which means that he is absolutely a reserved, practical, and quiet ISTJ. He’s a planner, he’s a realist, and he’s incredibly fond of taking a logical approach to achieving his goals. While he’s pretty rigid when it comes to following the rules (just check out his behavior in ‘Fair Game’ – S3, Ep3), not to mention the kind of alien who struggles to understand the emotions and feelings of others, he’s devoted to his allies – so much so that he happily makes battle cruisers after them like it’s no big deal.

Basically, Thor might be famed for his level head, but he is one seriously fair-minded and benevolent being, too. Which might explain why he was worshipped as a god for years, huh?

Bra’tac of Chulak (ESFP)

“I have spent 133 years worshiping false gods. No more!

‘The Serpent’s Lair’ – S2, Ep1.

One of Stargate Command’s closest allies,  Bra’tac (Tony Amendola) is here to surprise everyone with his Myer-Briggs personality type; say hello to our resident ESFP.

Bra’tac of Chulak (Tony Amendola) in ‘Family’ – S2, Ep8. | MGM, 1998.

I know, I know – he doesn’t look like your typical ‘entertainer’, but hear me out; Bra’tac is practical and resourceful, always looking for a new adventure, and he seriously loves living in the present and doing what feels right at that moment. He’s practical, loves being around other people (see how he champions his fellow Jaffa rebels), and a bit of an extrovert – especially when it comes to showing off his vastly superior battle know-how and skills. 

Throw in the fact that he wholeheartedly trusts his instincts and abilities when it comes to figuring out a solution to a problem, and you have the charismatic father figure we’d all love to have on our side when the going gets tough and the Goa’uld gets going. 

Oma Desala (ENFP)

“Many roads lead to the great path. Only the willing will find their way.”

‘Meridian’ – S5, Ep21.

Now, I know what you’re thinking; how on earth am I going to run a wise, non-corporeal being through the MBTI machine? As it turns out, all too easily.

Oma Desala (Mel Harris) might be one of the Ancients, but she has dedicated her entire existence to helping other beings (like, say, Daniel Jackson) ascend to the higher plane on which the Ancients now live – causing herself to become an outcast of her own in the process. Doesn’t that just scream ENFP to you?

Known to many as the ‘champion’, your classic ENFP is curious about others, obsessed with discovering the deeper meaning in life, and forever helping those around her to achieve – well, not their dreams, but their potential. And their potential – in every single instance, as far as Oma is concerned – is to ascend to a higher realm of being. 

Hey, it’s a living. Or afterliving.

Stargate | Janet’s Death Stings Now More Than Ever

War always has casualties – just turn on the news. We’re still crying and this is why.

Jonas Quinn (INFP)

“I don’t want you to exonerate me. I just want to be given the opportunity to prove I can make a difference.”

‘Redemption: Part 2’ – S6, Ep x.

Jonas (Corin Nemec) wasn’t exactly beloved by all Stargate SG-1 fans, but that’s largely because this optimistic Langaran scientist had some very big shoes to fill when he joined the show in Season 5. For those who need a reminder: he swooped in as Daniel Jackson’s replacement when the archaeologist died from radiation poisoning following a Naquadah-related incident. (Try saying that sentence five times really fast, why don’t you?).

Jonas Quinn (Corin Nemec) returns in ‘Fallout’ – S7, Ep14. | MGM, 2004.

Much like Daniel, Jonas is a hopeful optimist; he dreams of making the world a better place – and bettering himself right along with it. And, much like his fellow INFP/‘healer’ personality types, Jonas is defined by his sympathetic idealism and gentle compassion for others. While this is his greatest strength, though, it’s also his greatest weakness; he often finds himself swept along in the plans of others, accepting their opinions without question and allowing them to influence his decisions – not always a good thing. Especially in the case of that aforementioned Naquadah.

Basically, Jonas is a romantic. A hopeless, hopeless romantic. And, whatever you may think of him, there’s a reason this wide-eyed and awestruck scientist proved himself such a good fit with the rest of SG-1 in Daniel’s absence…
