Brooklyn Nine-Nine is a special sitcom that has its own silly brand of humor and some truly odd and charming characters. There is truly never a dull moment on this show, and thankfully, it has been renewed for a seventh season.
While Andy Sandberg is arguably the most well-known actor on the show and his character, Detective Jake Peralta, could be considered the protagonist of the show, it's ultimately an ensemble series with some really great characters. It makes perfect sense to look at the Myers-Briggs® Personality Types of these detectives and employees of the 99th Precinct.
Here are the Myers-Briggs® Personality Types of Brooklyn Nine-Nine characters.
10 Gina Linetti: ENTP
Gina Linetti may no longer be on the show, but her character (played by Chelsea Peretti) definitely lives on.
Gina is ditzy, incredibly opinionated, and thinks that the world (and the office) revolves around her. She loves to scheme and be silly, but she also notices everything and everyone around her. Her MBTI would be ENTP or "Enterprising Explorer." She definitely doesn't like anything on the list of stressors for ENTPS: "deadlines" and "boring, mundane task work." That last one is pretty funny since she works in admin at the 99th Precinct and is an assistant to Captain Holt as well.
ENTPs are "outspoken" which describes Gina, who tells it how she sees it and is often insulting Amy and the other characters. Her best zinger: "If Rosa had a twin, she would have eaten her in the womb."
9 Michael Hitchcock: ISFJ
Michael Hitchcock (Dirk Blocker) and Norm Scully (Joel McKinnon Miller) are the best of pals and are always referred to by their last names. It can be hard to think of them independently since they are always in scenes together and they're both disinterested in working hard.
Hitchcock's MBTI would have to be ISFJ or "Practical Helper." While both Hitchcock and Scully don't seem to care much about their lack of work ethic, they do care about the people that they work with. ISFJs are "loyal" and fans know that Hitchcock and Scully do enjoy where they work, even if they don't always show it (okay, they never show it).
8 Kevin Cozner: ISTJ
Captain Raymond Holt's husband Kevin Cozner (Marc Evan Jackson) is just as sweet and adorable as he is. They are basically exactly the same: serious people who don't show their feelings. If someone wanted to learn how to adopt a better poker face, they could definitely ask these two for advice.
When it comes to Kevin's MBTI, it would have to be ISTJ or "Responsible Realist." Kevin sounds like all of the descriptors: he is "practical" and "factual" and also very "reserved." Both Kevin and his husband win all of the fans over despite never being all that open with their thoughts and feelings.
7 Kate Peralta: ENTJ
Nasim Pedrad plays Kate, Jake's half-sister, who is wild and crazy and, therefore, makes for great TV. In her episode, "DFW," she has an unhealthy relationship with a guy named Kurt and gets in trouble at the airport twice. She even acts like there is glass at the restaurant where she, Jake, and Amy eat at, proving that she schemes pretty much anytime.
Kate seems like a wild child who is up for anything but since she often has something up her sleeve, her MBTI seems to be ENTJ or "Decisive Strategist." If she wants something (like a seat in business class on a plane, for example), she will figure out how to get it. Imagine what she could do if she tried harder or had a better work ethic. She is a "take charge" person and she also "prefers new challenges."
6 Terry Jeffords: INFJ
Terry Jeffords (Terry Crews) is sweet, emotional, and committed to living a healthy lifestyle (one that involves yogurt, of course). His MBTI would be INFJ or "Insightful Visionary." He's "quietly inspiring" and "sensitive."
Terry is someone who does the right thing and he's a great dad, husband, and friend. He is also someone who will "work with integrity" which is another descriptor of this personality type. Sometimes Terry fades into the background and isn't open about what he wants and needs, like the fifth season episode when he hurts his back from yoga and is stuck in a room for hours.
5 Charles Boyle: ISFP
Charles Boyle (Joe Lo Truglio) is close friends with Jake and would do anything for him. He's kind, caring, and a little bit strange. He has a great character arc and when he adopts a son named Nikolaj it's really heartwarming.
Charles's MBTI would be ISFP or "Versatile Supporter." These types "enjoy providing practical help or service to others" which is what Charles loves to do for his friends and coworkers. Charles is also "gentle" and "trusting."
4 Rosa Diaz: INTP
The show wouldn't be the same without Rosa Diaz (Stephanie Beatriz). She's the classic case of a tough character hiding a heart and a lot of feelings, but she makes this type of person feel very new and unique simply because fans love watching her so much.
Rosa is intelligent and quick-witted and brings a lot to every case that she works on. Her MBTI would be INTP or "Objective Analyst" since these types are called "detached" and "concise." Chatting with strangers about the weather and other "small talk" is not up Rosa's alley, either, and she likes to work on her own and just get on with her day.
3 Captain Raymond Holt: ISTJ
Like his husband Kevin, Holt's (Andre Braugher) MBTI would have to be ISTJ. Holt can't possibly imagine living in a world without "clearly defined systems and processes" (as the official description says). That is honestly Holt's worst nightmare.
Holt is such a wonderful, charming character because although he doesn't often smile and has a strange sense of humor (meaning that he really doesn't have one at all), but he is so caring. He wants the best for the other characters and does his best to be an example and a mentor to them. Holt doesn't like "change" or "noise" or "uncertainty" (but he does like his incredibly cute Corgi named Cheddar).
2 Amy Santiago: ISTP
Amy Santiago (Melissa Fumero) is a bookworm who can't help how dorky she is. She is literally so excited to go to work every day and can't stop with the office supplies. It's pretty adorable, and it's even more adorable when she and Jake start dating and eventually get married.
Amy's MBTI would be ISTP or "Logical Pragmatist." ISTPs "can remain calm while managing a crisis" which is exactly what Amy has done countless times. Her best, most shining moment is definitely the season five episode when the gang is in L.A. and they have to get Holt back to New York for a big interview. Everyone tells her that they want her to be her normal uptight self so she can get them out of the situation, and she passes with flying colors.
1 Jake Peralta: ENFJ
Jake is known as a very silly character who doesn't act his age at all, but he's such a nice guy that fans could watch him for hours (and, thankfully, there are many seasons of Brooklyn Nine-Nine so that's totally possible).
Jake's MBTI is ENFJ or "Compassionate Facilitator." Jake cares a lot about how well everyone at the 99th Precinct gets along, and he will do anything to save a character in trouble or solve a case. Although he might not see himself this way, Jake sounds a lot like this description: "As leaders, they tend to be adept at building consensus and inspiring others." Jake is also "people-oriented" and "energetic"... especially that last one. He often seems like a kid who ate too much junk food and is now super hyper. And he's just one reason why fans love this show so much.
