Found an SiFe woman! Tig Notaro.

She actually looks like a female Tom Cruise! SiFe, I'm sure now!

I think US Sen. Heidi Heitkamp might be an SiFe. I'm pretty sure she's Si-lead, anyway--eye-centricity, lightweight inertia, her eyes seem dulled at times. Her lips/smile look a bit Te/Fi, but she has the sort of accordion-bellows on her cheeks that come from lots of zygomatic smiliing. More importantly, she doesn't have any Te snippiness that I could see and has a very earthy-alpha qualia.

Oh, cool Kahawa, is that why she's so slow? That would be very fitting, actually.

Is slowness an Ni thing? I love how fast you went from "100% sure Si lead" to "Ni looks good too!" Ne much?

I didn't really analyse her too closely, but her eye intensity looked different from Si. And the way she told her story in the stand up routine - apart from forgetting the story (do Si's forget stories???), the way she kept pausing for 'insert deep meaning here' had a very non-Si feel to me. But that's just my un-scientific impression of watching that vid.

Oh, maybe she is Ji? Getting confused gain! Lemmie check with the database.

I am also a bit confused about her and I watched all these videos several times.
I also think she has a base of rigidity, but her energy doesn't seem to be receding or disengaging like Ji.
It came to my mind that she could be Te-lead, maybe with developed Pi slowing down her movements and make them look less snippy. Also this sharp humor reminds me of Te.
And I see more Si than Ni, I find her eyes rather dull than hypnotic, and her speech more anecdotal than cryptic.

I checked the profile "TeSi ll-- Seelie Female / The Faux-Fe Grandmother" and compared her with Beatrice Chestnut.
I think they could have a similar energy , quoting Auburn "Each head nod and angular movement still delivers it's closure, but with less of a hurry. The TeSi ll-- is more energetically introverted than the TeSi l---, due to a balance of introverted and extroverted energy."
But I also find their delivery is somehow different, but cannot really identify why (maybe Tig has less head nod/shakes), so I'm not sure.
