Charlie Sheen - TeNi?

The first time I watched him I thought he is SeTi, but after watching more interviews of him, I thought he might actually be a hypomanic TeNi.

I'm still unsure, though. His voice and gestures do seem Te/Fi, but to me it looks like he's got a wide, horizontal smile and well-developed zygomatic muscles which are usually indicative of Fe/Ti: 

Calin - H there! Nice to meet you. I definitely need to post the updates I've made to the Fe/Ti and Te/Fi definitions, the image you got there is a very iconic Te-lead look, in the overall sense. But to try and pick apart some of the things that make up this image, lets look at this:



One of the things that gives away Te, especially when it's prioritized above Fi, is a small area around the nose that is very taut. The mouth overall can expand, but the largest concentration of tension is toward the nose.

Another is the concave lips you see here. Notice how he's partially eating his lips (we can't see the pink of his lips much). This is because of how the levator labii muscles pull on the upper lip (in some it's the opposite and we get a really convex lip). Another effect of this subtle pulling is the corners of the lips are sorta hooked upward a bit. Here's an example of the hooking of the corners and the concave lip in another Te-Fi user:



And then when Sheen actually talks, often times his mouth makes asymmetrical gestures:



Some clarifications...

The major thing that visually distinguishes Te from Fe is the presence of these sort of tensions and asymmetrical expressions -- in other words, the dynamic motions of the mouth. The elements which are more static, such as the measurable wideness of a person's smile and whether the zygomaticus major muscles are toned, unfortunately don't tell us much about this dynamic use -- and are among the least reliable signals.

All things being equal, it's still true that wideness of smile is more typical in Fe but this is because of the diagonal direction the zygomaticus takes the mouth (versus the vertial direction of the levator). But the position of a person's cheekbones and facial structure can give Te/Fi users wide mouths, and has to be factored in.

The second dilemma is that the zygomaticus is actually used by most everyone to smile. It's a universal muscle and so all 16 types have it and "can" use it. This makes the question of differentiating Fe and Fi a bit different.

• If we only see the levator muscles used = super clear Fi/Te
  
• If we see the levator and zygomaticus = likely Fi/Te
  
• If we see only the zygomaticus = clear Fe/Ti

Te/Fi users can use the zygomaticus plus the levator labii muscles, while Fe/Ti users don't really use those small muscles close to the nose in any occasion except when experiencing deep feeling (such as a really really funny moment or something cry-worthy)

I hope this helps a bit.

edit: To give some contrast, here's an Fe-lead smile (no tensions from Fi present) and how it alters the look:

No problem.

Oh and just for a bonus, here's one I found that works as good reference too - with those same features more exaggerated. The zygomaticus major muscles are in use, but those upward-turned lip edges are there, and they're also causing the upper lip to slip out of sight.

Te/Fi

This one has that Delta look to me (a bit Gonomish, giddy) but I can't seem to find footage to verify.
