This was just a spontaneous thought so I'm not going to elaborate (I am actually procrastinating from work so I need to do this fast and get back to work welp), but feel free to do so in the comments. (English is not my first language so forgive the mistakes)

We got the boys' MBTI in I-land:

Heeseung- INFJ

Jay- ENTP

Sunoo- ENFP

Ni-ki- ENFJ

Sunghoon- ISTJ

Jake- ISTJ

Jungwon- ESTJ

if you're not familiar with MBTI, here's what the letters mean:

Where you focus your attention – Extraversion (E) or Introversion (I)

The way you take in information – Sensing (S) or INtuition (N)

How you make decisions – Thinking (T) or Feeling (F)

How you deal with the world – Judging (J) or Perceiving (P)

(The Myers-Briggs Company, n.d.)

For more information feel free to look mbti on google.

Overall I think they're pretty well-balanced!

They have 4 Extroverts and 3 Introverts

Extrovert Line - They take energy from being with people and social situations

• Jungwon, Ni-ki, Jay, and Sunoo

Introvert Line- They take energy from being by themselves (does not mean they're shy and don't like the stage-- they just need to recharge alone~)

• Sunghoon, Jake, and Heeseung

They have 4 Intuitives and 3 Sensors

Intuitive line (imaginative, curious, focus on possibilities)

• Heeseung, Jay, Sunoo, and Ni-ki

Sensor line (practical, focus on the present or the past)

• Sunghoon, Jake, and Jungwon

They have 4 Thinkers types and 3 Feelers

Thinker line (Objective, logic over emotions)

• Jay, Sunghoon, Jake, and Jungwon

Feeler line (Emotional and sensitive)

• Heeseung, Sunoo, and Ni-Ki

They have 5 Judgers and 2 Perceivers

Judging line (Decision making is organized, prefer structure)

• Heeseung, Ni-ki, Jungwon, Sunghoon, Jake

Perceiving line (Decision making is spontaneous, flexible, non-conformist)

• Jay, Sunoo

Most of their personalities are somewhat similar with difference of just 1 letter, but there also who are opposite (This is at least in terms of the letters, cognitive functions are a different story and can yield deeper insights).

• Jake & Sunghoon- both ISTJs

• Jungwon- Extroverted version of Jake and Sunghoon

• Sunoo- Exact opposite of Jake and Sunghoon

• Sunoo- Feeler version of Jay

• Ni-ki- Extroverted version of Heeseung; Judging version of Sunoo

It's important to also know that people have both aspects, we just prefer one more than the other. For instance, I can be 75% introverted, and 25% extroverted. I can go out and genuinely have fun with others, but I would prefer to be alone or need to be alone most of the time. I'm also 55% Intuitive and 45% Sensing, this is where the lines blur; I like abstract stuff and possibilities, but there are some situations I am grounded and practical. We don't know the boys' percentages of these aspects, so let's just take these things with a grain of salt!

I know MBTI is not the be-all and end-all and personalities may change, but their current mbti can provide us some insights about each member. Right now, although we have I-land to see their interactions, we still don't have enough content to see their dynamics as Enhypen. I'm not going to psychoanalyze them, but I'll be sure to keep an eye on their interactions with each other and how their personalities affect the group as a whole! How about you, what do you think of their personality dynamics? How do you think these individual personalities would impact their teamwork?

Edit: Added Ni-ki and Sunoo's almost similar types
