So I have attempted to type Justin Timberlake based on one video of him being interviewed by Oprah. I think due to the question asked by Oprah about his ex girlfriend Britney Spears, he may have not felt as emotionally invested in the conversation. But I did notice that despite appearing friendly and smiling, there was no emotion behind it at all and his smile appeared rather placid, I think because of this he might be a Ti lead. He also tends to stutter in a specific way while speaking. Ironically I found that he also had both Ji and Je moments of movement, so it is possible that he could have a developed inferior Fe perhaps.
Also to add on, in terms of Se, he definitely had locked on eyes, he would look away for a second and had very pointed toggled, his eyes only toggled to three or more distinct points before returning to face Oprah.
I'm out of practice with typing, but my first impression is SeTi (I looked at different videos than the one posted above because he seemed very uncomfortable in that video, which can change someone's vultology). I see bubbling momentum and eye-centricity that makes me think P-lead. He also reminds me a lot of Eminem, who is SeTi. This is only based on watching a few minutes of video though, so it could definitely be wrong.
Ah I see what your saying. Its true he has a lot of similarities with eminem. Yes in this interview he probably wasn't being himself and he kept withdrawing his eyes. But he still had a lot of bubbling momentum even though his Ti kind of halted his emotional expression a bit.
It seems to me like he has the Pi grounded energy that affects his Pe lead tendencies and he also has quite pronounced Pi moments, like 3:22 - 3:32:
He also seems to have pronounced Je - adaptive Fe; it can be seen in the form of warm swelling, as shown in the following gif:
There are probably other motions as well, but I'm too lazy to search for them.
If he were to remind me of some other celebrity, he reminds me of Kurt Cobain, who's most likely another polarized adaptive SeTi (who might also have had conscious Je, idk).
So, adaptive SeTi I-II for Timberlake imo.
I think next time I wanna make those short video clips to use as examples, but I don't know how. I agree he does seem like a polarized Se-Ti type in this video specifically, perhaps because I'm still new to typing I can only point out very generally observable movements, but you seem to have a better eye for it.
