Which MBTI type are the characters from The Big Bang Theory?

The Big Bang Theory: “An American sitcom created by Chuck Lorre and Bill Prady.”

The Big Bang Theory is a famous TV show that can be enjoyed by people of all ages. However, one of the main things that made this show such a success is the screenwriters ability to give each character a unique and exagerated personality.

One of the main characters on this show is Leonard. Leonard is often classified as an ISFJ. He is more introverted than extroverted as he has to think before he talks and often listens to others peoples problems whilst not talking too much. He is a definite sensor as he often gets confused when other characters do something out of the normal in society, such as break a rule or invent something new. He is also an F as is he is often concerned whether he hurt people’s feelings. Leonard is a strong J and doesn’t go out of his routine very often.

Sheldon is an introvert. He enjoys being by himself and enjoys deep intellectual stimulation, a trait of an introverted intuition user. Sheldon is intuitive, as he has an amazing ability to think comprehensively and analytically. Sheldon is a definite T and has a very difficult time reading other people’s emotion. He is brutally honest and is very concerned about science and logicstics. He is the strongest J on the show always caring about routine and being organized. He is always worrying about something, adding to the humour in the show. Therefore, Sheldon is a strong INTJ.

Raj is harder to type. He rarely talks and is often worried around girls. This makes him an IXFX. He often does random things and thinks up random jokes, making him an INFP, with his Ne function.

Howard is an extrovert as he often acts before he thinks and can be very talkative at times. He is an intuitive person, purely based on his ability to engage in conversation about super powers and super heroes, making him more of a “thinking outside the box” type. He is a strong thinker, often getting himself in trouble in social situations. He is also a perceiver as he often gets himself in strange situations. Howard is an ENTP.

Finally, Penny is a strong ESFP. She will talk a lot when she wants to and she often considers the other characters weird, making her an E and an N. She can get emotional over small things, making her an F and she is lazy without much of a goal in the future, making her a P.

    Sheldon is an misguided INTJ his movement patterns cofirms that.

  2. Lakota says:

    A lot of Sheldon’s behavior seems introverted, was there anything in particular that made you swing toward E? I understand that he talks a lot, but he is very comfortable in his little bubble of an apartment so wouldn’t feel the need to hold back at all, plus he is mostly surrounded by I’s. I think it’s interesting that you type Raj as an INFP, I never saw it before but now it makes sense.

  3. ella says:

    Yea, I stopped reading after you thought Sheldon was an extrovert. Thumbs down. A more introverted person is hard to find.

  4. Deepti says:

    It’s something I hadn’t considered before, but I can definitely see Sheldon as a poorly developed extrovert. He seems to think he is the centre of his little group and always has something to say. Moreover, like ExTxs, he will continue relentlessly on with his own train of thought and refuse to get sidetracked by other people’s inputs, or brush them away as inconsequential. I do agree with the first comment that he is closest to an INTJ, though, but I would not completely dismiss the idea of him being an E of some kind.

    Leonard an ISFJ? I always thought he was INFP. I agree with the other three. Raj is definitely an INFP.

  5. Sarita says:

    I am unsure if Sheldon is an “i” or an “e”. He appears to have a social disorder, which I think is the reason he is very open in certain situations, rather than extroversion. I would agree that Leonard is like my ISFJ mom and Raj is like my INFP self.

      I one hundred percent agree with that. Sheldon is hard to type, because on screen he is always talking because he is the most popular character amongst the audience, and they need him to say lots of funny things. However, we also have to keep in mind that most of his favourite activities are introverted activities. So it’s a toss up.

      • An ISTJ says:

        I think he is introverted but comfortable enough around those he hangs out with to speak his mind. He knows them well and they know him because he and Leonard are sort of a package deal, since Sheldon saved Leonard’s life once.

  6. Mother Monster says:

    I think Sheldon is an INTJ without a doubt. Everyone has both introverted and evtroverted functions. The letters are just the base or the basic building blocks. The functions have to be considered a bit more. An INTJ’s second function is extroverted thinking, which makes it one of their stronger functions. An INTJ is an introvert, but when someone wants to talk about an interesting subject, they could lecture for hours. And they tend to have a high regard for themselves. Thats just what I think πŸ™‚

  7. Timeless says:

    Sheldon seems to be in a category outside of the MBTI types and inside one of the autism spectrum disorders, namely Asperger Syndrome, if we are to judge from his gait, his repetitive patterns and significant social ineptness.

  8. Uber Survivor Fan says:

    I’m so tired of seeing Sheldon listed as an INTJ, there is nothing INTJ-like about him. He is an ESTJ with Asperger’s Syndrome.

    E/I – Just because he has poor social skills does NOT mean that he is an introvert. The guy never wants to be alone, he is always with people, and not only that but he is always trying to be the center of attention. Nothing introverted about him.

    S/N – Also not an N. People think “Physicist = N” but that isn’t the case. While most FAMOUS physicists are N users (Einstein, Feynman, etc.), the majority of people in the field are SJs. Stereotypes aside, he is clearly using Si. He uses it constantly. He never thinks of anything new and he is constantly thinking about what has happened in the past, what has worked in the past, always dropping anecdotes, etc.

    T/F – I agree that he is a T, but that isn’t why he has trouble reading emotion. He has trouble reading emotions because he has Asperger’s Syndrome. It is also why he doesn’t get sarcasm.

    J/P – I agree that he is a J. He is the most J-like person in the group.

    From a cognitive functions point of view, he is clearly using Te-Si, not Ni-Te.

    From a stereotypes point of view, minus the Asperger’s he is a walking stereotype of an ESTJ. He is obsessed with credentials, like how he is constantly mocking his friend for only having a Master’s degree while flaunting his two doctorates every chance he gets. He is always trying to lead everybody. He thinks he is brilliant but he isn’t that bright. He isn’t creative in any way, he never thinks of anything new. He follows social conventions like a sheep, even if he doesn’t understand them or thinks they are stupid. And the list goes on and on.

    So in conclusion, Sheldon is an ESTJ with Asperger’s Syndrome and NOT an INTJ!

    • Bob says:

      The funny thing is, he was originally listed as an ESTJ. But he was changed to INTJ by author due to complaints

    • Aimee says:

      I agree with this partically but think that Sheldon is an ISTJ. INTJs aren’t all as arrogant as they are made out to be and they’re definately not the only type that can be arrogant. Sheldon is scientifically and mathematically intelligent at the detriment of other types of intelligence. The problem with typing Sheldon is that he is a nerd stereotype rather than a real life personality. He is too stereotypically Aspergers to function.

      e/i – I see Sheldon listening to other people as an observer. He strikes me as a essential observer (IS) more than anything else. He doesn’t have many friends and shuts himself off from the world when things don’t go his way. He actually doesn’t seem too fussed whether he has people around him or not.

      s/n – Sheldon does come up with new ideas but they seem to be created with a overly strictly logical, step by step process rather than a more abstract one of intuition. He uses Si constantly (his dominant function). As an ISTJ he is skeptical of trying new things or new ideas. Is a stickler for details and has a past memory of an elephant. INTJs are generally not as rigid as he is. I don’t see that there is anything ‘creative’ or ‘imaginative’ about him at all, but this is not really what N is.

      t/f – I agree with the statement that he is thinking but that isn’t why he has low social skills, I agree that it’s his aspergers.

      p/j – Definately an J without a doubt. His rigid personality causes a lot of his drama with other people. I think an ISTJ overall.

      • Nilay says:

        Exactly, Sheldon is a person with thinking type and not feeler. And he is ISTP, not ISFJ. Why is that so ?
        1. Both look much same.
        2. It’s only trait who is so frightened for hurting one’s feeling because of there IP nature.

        • tatl33 says:

          I said Leonard was ISFJ, not Sheldon.
          Were you referring to Leonard? If so, your reasoning is quite good and Leonard does display high traits of ISTP

    • I think you are right on this.

  9. Devon Kennedy says:

    Haha, before I read this, I made my own guesses on their personality types. We were exactly the same on Sheldon, Raj and Penny. I was almost there on Howard too (I said ESTP). I was only totally off from you on Leonard, because I said ENFP.

  10. Nilay says:

    This is what I think,

    Penny – ESFP
    Raj – INFP
    Sheldon – INTJ (XD)
    Bernadectt – ISTJ
    Amy – INTP

  11. admalouf says:

    I think you’ve got some stereotyping tendencies. Sheldon is definitely not an INTJ…I’d say more INTP
