I'm doing this just for fun and this is purely based on my observation and you don't have to agree with me so feel free to comment your opinion below for a healthy discussion. Also, I'm currently a passive English user due to living in a Non-English speaking country so pardon the grammatical error if you find any. 

Anyway, I've read this book called Multiple Intelligences by Howard Gardner a while ago and this analysis sort of popped up in my head while I was watching the recent episode of BTS! Run (episode 32).

To put it simply, in his book, Gardner explained that people have different types of intelligence and to quantify them to just mere numbers does not fully portray the complexities of human intelligence as a whole due to its nature of having many layers. Basically, he believes that IQ tests are bull and we cannot have one fixed template of method of teaching in order to educate people. This would explain the fact that some people could learn better by having visualization rather than just by learning the theory and abstract concept alone. This does not mean that they are not smart, it just means that they think differently. This would also explain why some people are street smart rather than textbook smart and both are still equally intelligent. You can look up the brief explanation here: http://www.tecweb.org/styles/gardner.html

Before continuing to my analysis of BTS members' types of intelligence, let me explain the 7 main types of intelligence according to Gardner. Also, I have to add that people have all of these 7 types inside but they all fall under spectrum. Basically, people have all of these intelligence but with varying degrees depending on the person.

Those main 7 types of intelligence are:

1. Visual-spatial - If you have this type of intelligence you have to use visualization to learn things. You are also very in tune with your surroundings. You like to draw, give examples to explain things, and make diagram. 

2. Bodily-kinesthetic - When you have bodily-kinesthetic intelligence you are very in tune with the movements in your body. You would be a very good dancer and/or athlete. 

3. Musical - When you are musically intelligent you have a high sensitivity toward rhythm, beat, melodies, and sounds. People with musical intelligence of course have the ability to think musically and like to surround themselves with music. 

4. Interpersonal - When you have interpersonal intelligence basically you are people person and you are able to sense other people's feelings easily, you are understanding, and you are street smart by collecting informations through experience.

5. Intrapersonal - You are very introspective and goal oriented and you like to explore things and learn things on your own to understand them better. You understand yourself very well and are very deep and emotional. 

6. Linguistic - You are very good with languages if you have this as your dominant type of intelligence. You are also very articulate and are able to express things well with words. 

7. Logical-mathematical - If you have logical-mathematical intelligence you are the textbook traditional definition of "smart". You think logically and you have high reasoning abilities. You like to calculate things and observe patterns. 

Analysis

(Order based on fanchant and I also gave them nicknames that I think suit them best).

Kim Namjoon - The Cerebral Leader

Namjoon is the definition of textbook smart due to his dominant Linguistic intelligence and Logical-mathematical intelligence, making him The Cerebral Leader that he is. Combining these two would explain his high IQ and how he would make sense of things logically. The culmination of his logical-mathematical intelligence, his high linguistic intelligence, as well as a touch of intrapersonal intelligence, would explain why he was able to learn another language quickly just by watching TV series alone (mind you, it is not an easy thing to do). He said that first he would watch it over and over with Korean subtitles, then he would replace it with English subtitles, and then he would remove the subtitles completely. To be able to think like this he would have to memorize the Korean subtitles first and associate it with the scenes, after that he would match the Korean subtitles with the English subtitles, and, finally, after putting them together he had to learn to match the situation with the things that he had memorized. That is just the surface because in his mind he had to collect vocabularies and make sense of the grammar after, not to mention understanding cultural context of things required added research outside of just watching Friends. That's basically what you do in an ESL class but he did it on his own which is remarkable. This linguistic intelligence also would explain the complexities and the multilayered meanings in his lyrics. Other examples of people with high Linguistic intelligence are Emily Dickinson, Maya Angelou, Tablo, Nas, and Eminem (there are many more but those people are the ones I could think of from the top of my head). 

His secondary intelligence are intrapersonal and musical. He has some degree of Intrapersonal intelligence because he is emotional and introspective by nature and this showed in his highly introspective lyrics. He also has some degree in musical intelligence since he is able to produce and compose songs as well.

These intelligence are needed in order to become an idol group's leader because you need to think strategically in order to be successful in the market whilst also having the inherent talent. This connect with additional theories in pop culture on the aspect of understanding taste but I won't discuss that here.

But, then again, he is also lacking in some areas. For example, the lack of bodily kinesthetic would explain his dancing skill that he had to work really hard for and his extreme clumsiness. He is also a bit lacking in his interpersonal skill and this is something that he had to learn overtime and it does not come out naturally. If you pay attention to the interviews he would sometimes get tired of explaining things or seemed quite frustrated by repetitive questions and if this is not supported by the other members finding it funny it would come across as rude (e.g. "Strong Power, Thank You." and "Heartbreaker", ya dig?). For this reason, he needs to rely on others for emotional stability and that is why he is able to be complemented by the other members with other types of dominant intelligence to support him.

Kim Seokjin - The Charmer

Linguistic, Interpersonal, and Intrapersonal are Seokjin's dominant intelligence. All of these intelligence combined would explain why he has that unexplainable X factor without even trying too hard, making him The Charmer. Yeah, he might be good-looking but his use of gesture and his command of his mannerism contribute to the fact that he would oftentimes be the first one to be noticed by people rather than the other members.

All dad jokes aside, the combination of these intelligence make Seokjin quite persuasive thus explaining why people in general would like him (note the way he said "I'm coward but come on, come on" when he was doing Flinch in James Corden). The fact that his first aim was to be an actor also showed that he has confidence in memorizing scripts which is contributed from his linguistic intelligence as well. Now you might think that he does not have interpersonal skill because he is an introvert, but actually it does not matter whether you are an introvert or not to have interpersonal skill. Seokjin had shown that he could carry the situation well when he is MCing and the fact that he is very good in variety shows outside of the shows he does with BTS also explain his interpersonal intelligence. Seokjin is also able to project things to others because he had shown that could be very confident when he is good at something or he has something that others don't, like his guitar skill and his cooking ability, for example. His interpersonal skill is also shown when he would support s emotionally as well and the fact that he thinks that Yoongi complement him well and that's why he felt most comfortable with him as his roommate is quite telling. 

He also have some degree in logical-mathematic intelligence explaining the fact that he is the type that thinks studying and knowledge are necessities (note the fact that he is currently doing his Master's degree despite being an idol). This also connects to his intrapersonal skill because he likes to learn new things and gain new skills in his own time, showing his introspective self. 

The person that I could think of who is similar to Jin is the actor Steve Buscemi. Now, Buscemi is not conventionally good looking like Jin but he is a persuasive charmer. Buscemi is also the type who could charm others with his great command of his mannerism and his persuasive language skills (have you seen him in Ghost World and SNL skits? They are brilliant!).

Like Namjoon, he is also lacking in the bodily kinesthetic intelligence but the reason why he is much slower in learning the dance movements and often required extra help is because his visual-spatial skill is also something that he had to learn overtime.

Min Yoongi - The Musical Genius (jjang jjang man boong boong)

Musical and Intrapersonal intelligence are Yoongi's dominant intelligence. I remember that he mentioned in the BTS countdown that he would constantly write songs and even would think in terms of music daily. To me, that showed signs of being a musical prodigy. I am glad that he was able to hone this skills because the agency gave him the facilities to do so. Just imagine what he could do if he was able to gain access to hone his skills much earlier? Anyway, to be able to compose music, you need to have a good command of reasoning skill as well and be in tune with patterns and this pattern is somewhat abstract so he has some logical-mathematical skills in that respect. Think of it like this, if you see Fibonacci sequence you notice that the pattern immediately in terms of numbers but with music you create patterns and would match them with something more emotionally envoking, in this case they are musical notes and this connects to his intrapersonal skill. 

In terms of his intrapersonal intelligence, I think Yoongi is much more introspective and much more goal oriented than Namjoon. This is because he is much more introverted and in tune with his own thoughts. This is proven with the fact that he took initiative to follow his dream to become a musician even though his parent were againts the idea, but in the end he was able to convince his parents that it was all worth it. He is the type who would say that "actions speak louder than words."

He also has some degree in bodily-kinesthetic intelligence and visual-spatial intelligence because he is very good at calculating distance and angles, making him very good at playing basketball and doing archery. He could also dance quite well if he is in the mood. I think Yoongi is also somewhat linguistically intelligent because he has shown from time to time that he is actually able to keep up during English interviews but he is a passive English user and would rather say what he needed to say in short sentences or if it's too long he would just use translator than think for too long to say what he wanted to say. Also, Yoongi is also able to write lyrics that is poignant and he could express himself well with his songs rather than directly thus making up for his lack of interpersonal skills. His lack of interpersonal skill showed in the way that he just say whatever he wants regardless of what other people feel. Yoongi, despite his stage name, does not sugarcoat his words. He is the type that would tell the truth even though it would hurt others. But, even so, this type of attitude is necessary in order to stay "woke", so to speak. But, again, this is made up by his art, especially the beautiful heartfelt songs he had written (e.g. First Love and The Last). His style of lyrics are brutal and honest and he is not the type to use much metaphor or figurative languages like Namjoon but he used his savagery instead to spit fire. 

Anyway, his more sensitive side could only be brought out by others, specifically Jimin, Jin, and Hoseok.

Jung Hoseok - The Rock

Hoseok's dominant intelligence are bodily kinesthetic, musical, and interpersonal intelligence. Hoseok's high bodily-kinesthetic intelligence would make him able to learn new choreography very quickly. I remember a statement, but I don't remember from which video, saying that Hoseok was able to learn a particularly difficult part of the choreography in DNA in only several minutes whereas the other members took quite a while. If you notice his 2016 MAMA Boy Meets Evil performance, for example, you can see that his steps are very stable and he is definitely not clumsy because to be able to be that flexible and move accordingly but still not injure yourself require the combination of inherent talent and also a good command and control of one's body.

His skills are also further strengthened by his musical intelligence because he is in tune with the rhythm of the songs and the beat. His musical intelligence is also shown in the fact that he is actually a good singer, could rap well, and could write his own songs (1Verse ftw). He's not the Golden Hyung for nothing. 

The reason why I named him The Rock is because the culmination of these skills, in my opinion, would make him quite a good candidate for the role of a leader. But I think his leadership role would come into play behind the camera, not in front of the camera. For example, according to the members, Hoseok is very disciplined because he would naturally wake up early and he is the type to be prepared early (Bon Voyage, anyone?). In my opinion, he would be the type of person who is very strict when it comes to schedule and the type who would encourage other members when they are having a hard time. 

He has a high intelligence in the interpersonal area because he could actually command the stage easily and that is why he is the main dancer. He is also not afraid to cry in front of others, he doesn't have trouble conveying his emotions directly, and he is very expressive, making him the mood maker of the group. 

Park Jimin - The Empath

Intrapersonal, interpersonal, and visual-spatial are Jimin's dominant intelligence. From what I can see, Jimin has a good balance of interpersonal and intrapersonal skills. This balance made Jimin become one of those people who couldn't help but to feel for others and, in turn, would make him very sensitive and also in tune with others' emotion. Jimin is the type that would know just what to do to comfort others, making him The Empath. His personality is also very contagious and I bet my that most people would go "awwww" when they see his natural aegyo (Jimin, you cute llittle . ). The combination of these two intelligence is needed in order to balance those who are logical and calculating like Namjoon and Yoongi. His presence would bring out the softer side in others. He would also make people care about him very much and make people feel the need to protect him. This would also explain the infamous "Jimin Effect" making him quite charming as well. Even so, his empathic nature is the one that stood out the most. 

When you divide the two intelligence, his intrapersonal skill is shown from the fact that he is VERY goal oriented. He set his mind to be a dancer and he knew that he has killer moves so a dancer he became. As for his interpersonal skill this is shown very well when he soothed Namjoon when he cried and the way that he enthusiastically supported Yoongi during a basketball game. 

Jimin's bodily kinesthetic intelligence is actually his secondary intelligence because he is also somewhat clumsy but given enough support from his visual-spatial intelligence, he would get used to the surrounding very quickly and he could command the stage very well when he is performing. Take note from his MAMA 2016 blindfolded performance, for example. I am very sure that he would memorize just how many steps it would take from one end of the stage to the other and how many turns he should make to face the audience throughout the whole performance. That is not easy. Like, goddamn.

When you mix all of his dominant intelligence together you would get one very tactile and sensuous being, thus explaining the fact that he is very touchy with other people. It's so cute, goddammit. . 

On another note, because he is extremely emotional, he always thinks about what others think of him too much and this is why he clicks with Tae since he is able to support and encourage him to be more comfortable in his own skin. Also, due to this, he is also the type to overwork himself from practicing too much and has a habit of being too critical of himself by being a perfectionist. We should be glad that the other members would constantly remind him to take care of himself better. 

Kim Taehyung - The Wild Card

Tae has a high interpersonal intelligence and because of this he is extremely street smart and has many hidden talents and even potential abilities that he is able to develop quickly. I remember when he knew the answer to a question regarding how to tell if a strawberry is ripe. He said that he heard this information from his grandmother's friends. To me, this showed that he can actually apply the things he had learn through experience quite quickly. His high interpersonal intelligence is also shown in the fact that he is the type to make friends easily and able to move people's hearts with his charm. Different from Jin, his charm actually came from his emotional side rather than his skill to persuade. This is reflected in the way he expressed things toward people. A good example that showed his interpersonal skill is from his solo VLive, his ment during concerts, and the letter to Jimin. Even though he is not conventionally articulate, he made up his lack of linguistic skill with his interpersonal skill.

He is also the type to seek comfort in others, making him quite emotive. His street smart is also able to make him learn languages as well. I am highly sure that he is the type that would learn English from playing video games and would learn Japanese from anime. His extreme interpersonal intelligence is also shown in the way that he is able to act. I am sure he practice a lot and I actually saw a clip where he use earphone to listen to the dialogue as he read AND as he acted out the scene in front of the members. He needed all the practice he could get to make up for his lack of linguistic skill to memorize the words. BUT I think that as he matured, if he continuously work on his language skill, he could actually have a good command of his linguistic skill. 

His visual-spatial intelligence is also quite high because he seemed to be the type to learn things visually to be able to understand things and he is quite observant because he would notice things that others don't. This is reflected in the way that he takes photography, most notably the way he would emphasize on texture.

I think I understand why BigHit kept him a secret for quite a while because, for one, his presence is striking (his gaze is no joke) and, two, he has so much potential. Also, he is unpredictable by nature with many hidden skills, making him The Wild Card that he is. He is basically the jack of all trades so it all just depend on Taehyung's choice as to which skills he wants to really perfect in the long run. Also, he is musically intelligent as well because he had tried to compose some melodies before and also I saw from this video that prove that he has a perfect pitch and there's also a blog post that support this claim further. 

Like, , he is one smart and talented dude.

Jeon Jungkook - The Architect

Jungkook's dominant intelligence are his high visual-spatial, bodily-kinesthetic, and intrapersonal intelligence.

His primary intelligence is visual-spatial. He is very good when it comes to anything visual. For example, he can draw very well, he is also a very good photographer, and he is able to make gorgeous shots when he did his G.C.F. in Japan featuring Jimin. I mean, have you seen that panoramic shot when he went down the escalator? It's ing beautiful.

As for Jungkook's photography skill, he has his own different style from Taehyung. Taehyung is more avant-garde whereas he tends to search things that would please the eyes. Jungkook definitely has a keen eye for things that are aesthetically pleasing and I wouldn't be surprised if he would direct an actual legit music video or even direct movies in the future.

He also showed quite a high bodily-kinesthetic intelligence as well as intrapersonal skill. His bodily-kinesthetic intelligence is shown with the fact that he is also a great dancer as well (even though Hoseok and Jimin command the dance more). His kinesthetic intelligence can be seen from the fact that he is very athletic and able to control his body well when doing challenging sports. This would also bring out his visual-spatial intelligence as well because certain sports require the ability to take aim and to understand space and distance perfectly other than having the agility and endurance. The ones that stood out to me the most are when he did wrestling and when he bowled. 

Jungkook also combined the two intelligence above with his high intrapersonal skill thus making him the Golden Maknae. His high intrapersonal skill also made up for his weakness in logical reasoning because he is able to learn by accumulating experience points silently. Jungkook is very introspective by nature and he likes to explore things on his own to gain new skills and he is also very competitive. And somehow, for some reason much to the hyungs' frustations, when he learned something new he could get really good at it quickly (note when he learned how to waterski for the first time). Like, damn son. The fact that he said that he is learning how to produce songs also would further heightened his musical intelligence as well. All of this intelligence combined will make him able to create things with ease thus making him The Arthitect. He is definitely one smart cookie.

I would like to stress that all members of BTS have musical intelligence (as in any musicians) but some members have a higher degree than others. There's also another type of intelligence and they are called "Naturalistic Intelligence" and "Existential intelligence"(refering to this chart). Naturalistic Intelligence refer to the understanding of other living beings and the Existential intelligence refer to people who would often question things about life; a philosopher, in a way. All of BTS members have naturalistic intelligence because they all love animals (even though some of the members are scared of insects and bugs lol). This can be seen in their interaction with the dog in one of the Run episodes and the pets that several members owned. However, the existential intelligence is actually shown by Namjoon and Taehyung. Both of them, to me, are the philosophers of BTS. They are polar opposite but their mutual view on life and their nature to question existence made them complement one another perfectly. One would put it into words and the other would express it visually (e.g. Namjoon's lyrics and Tae's photography).

In conclusion, all of the members are talented people who have their own sets of strengths and weaknesses and I'm glad that they all complement one another very well.

This is just my observation. You're welcome to put your thoughts down in the comments below.
