Type my Twin Brother

Hello leeleechirps2.0 ,
Thank you so much for being patient, here it is!

For your twin brother, there may be a bit of interference with the alcohol, which is a sedative and can cause a slowdown of energy, a more sleepy appearance, and casual/relaxed posture. But I'll be approaching this analysis under the assumption that he's in a native-state and/or not affected in any way.

Beginning with the second question at 0:28:

0:28 - Ni Hypnotic Eyes + Ni Lowered Eyelids
0:29 - P Ongoing Movements (casual body posture)
0:30 - Te Dismissive Browraise? + P Head-tilt
0:31 - Ni Hypnotic Eyes + Ni Lowered Eyelids
0:34 - Se Eye-Head Parallel Motion + Pi Inertial Energy
0:36 - Se Eye-Head Parallel Motion + Pi Inertial Energy
0:37 - Te Dismissive Browraise + Fi Convex Lips
0:38 - Pi Inertial Energy + Ni Hyponotic Eyes
0:39 - Te Dismissive Browraise + Ni Permanent Stare
0:40 - Te Dismissive Browraise + Ni Permanent Stare
0:41 - Pi Inertial Energy (recedes back after every little push)
0:42 + Ni Permament Stare
0:50 - Pe Eye-Toggling
0:53 - Fi Grimmace? (n/a)
0:55 - Te Dismissive Browraise + Fi Convex Lips
0:56 - Pi Inertial Energy
0:58 - Se Eye-Head Parallel Motion
0:59 - Te Dismissive Browraise + Te Matter-of-fact ("next question")
1:02 - Se Eye-Head Parallel Motion
1:07 - Te Dismissive Shoulder Shrug
1:07 + Ni Permanent Stare
1:18 - Pe Eye-Toggling (up)
1:21 - Fi Convex Lips + Te Matter-of-fact ("being pressured to do videos")
1:22 - Te Deadpan
1:22 - Ni Permanent Stare
1:28 - Se Eye-Head Parallel Motion

Prominent Pattern:

- Ni Hyonotic Eyes
- Ni Permanent Stare
- Ni Lowered Eyelids
- Pi Inertial Energy
- Te Dismissive Browraises
- Te Matter-of-fact articulation

Analysis:

Overall Roman's demeanor can be characterized as 'nonchalant'. All his movements carry very minimal energy, and he varies from this sedentary baseline only briefly... then quickly deflates back to a very relaxed, fluid body posture. There is an inertial energy to his movements which are accompanied by a very permanent Ni gaze. His eyes appear hypnotic, zoned-out and carry a permanently lowered top eyelid. This confirms he is most certainly a P-lead Ni/Se user. I'm quite certain he's Ni-lead but on the off-chance his Ni is being accentuated by the sedative effects, polarized Se-lead would be the only other possibility.

J Functions: These are a bit harder to see because of how much P-energy he has, with his J signals being far between. But upon closer inspection, this is what we see:

1:58

^ Te Dismissiveness + P head tilt

1:07

^ Te Shoulder Shrug + Ni Hypnotic Eyes

0:37

^ Te Dismissive Browraise + Fi Convex Lips

We see in these that his overall "nonchalant" demeanor is coming from his Te matter-of-fact demeanor. We also see this reflected in his psychology in various places. His replies are off-handed, brief (briefness or to-the-point is often a motif for Te articulation under a Pi function), deadpan, etc. There is no effort made to embed more charisma or charm into his replies, but instead they are merely tossed into the environment.

Here is a composite image of some of the expressions we see:



Notes:
Given the context, his attitude and overall demeanor, I feel he might be NiTe-Se (polarized across the P axis) or just NiTe, although I cannot confirm subtype entirely from this video. The NiTe-Se is an IST temperament and tends to be very lacking in the mysticism associated with the Ni-heavy Ni-lead. I would see him fitting the following subtype description from this post:

He also has elements of the NiTe "Jester" from the book. He seems like he'd be a bit devious, sarcastic, ball-busting, if a bit understated in his approach. Anecdotally, I have an uncle just like him.

I hope this was a helpful analysis!

I'd love to learn more about your brother's personality; what he's really like and what he's into.
