Some of my own observations:
- Generally unwavering, stays in one position throughout the entire video
- Limited facial expression
- Love the permanent smile!
- Doesn't feel the need to fill in silence, i.e. you like to think about what you are going to say rather than "thinking out loud"
- Most of what you say comes out seeming well thought out (whether it is or not) and coherent without a lot of interjections (like "um's" and "like's") and without many or any tangents
- Talk about Socionics seems to concentrate on how things fit together logically
So, yeah, I think that fits well with the IJ temperament and leading , specifically LII, if I am remembering correctly what Rick said about them.
