Examples of Socionics Alpha types

[The Martrix]

My weird totally Si-based intuition is that she's sensing but rational, so LSE or ESI.

tbh she fits my mental image of SEI too, but I've met a bunch of women that vibe similarly physically who were not SEI (but rather those types I mentioned.)

I see. I would still go with SEI for her because her expression is very open, not closed like ESIs.
