Let's see...well, basically her role in Veronica Mars and her general demeanour in interviews and the like. Her role in Heroes basically just confused me, so I can't use that, and I don't think I've seen any of her films. I do think think she has a very light-hearted and sporadic sort of personality unequilavent to basically anybody else - and no, I don't think that necessarily means ILE. And that is where I am at.
I think the following interview would be enough to convince me of Kristen Bell's ESE-ness, even if I'd never seen anything else about her:
I found the following exchange particularly telling:
Craig Ferguson: "Wolfgang Puck is on tonight! [...] He's Austrian!"
Kristen Bell: *classic ESE half-smile of incomprehension, followed by laughter*
Kristen Bell (still laughing): "Okay?"
I've only ever seen that sort of half-smile of incomprehension in ESEs. It's like, there's something going on that they don't understand, and they feel like maybe they should understand it and they'll look stupid for not understanding it, but on the other hand maybe they're not expected to understand, and they really have no idea how to respond, so they get frozen in this half-smile, trying to maintain the Fe mood but not sure what the Fe mood should be, hoping someone will explain what's going on.
Her Veronica Mars character was definitely more aggressive and serious than one typically thinks of ESEs, but I think interviews such as the one above tend to reveal more of her true nature.
I'm also becoming increasingly convinced that Craig Ferguson is some kind of Alpha. ILE maybe? He consistently seems to have the best, most comfortable interviews with Alpha celebrities. And his interview with Rosie Perez, who I would type as SEE, was decidedly awkward.
Quaero Veritas.
I'd be ready to acknoweldge Craig Ferguson as ESE. He has a different style from Conan O'Brian. He seems like someone I'd like to hang out with--relaxed and friendly with a hint of nerdiness. Contrast with Conan O'Brian who is more edgy and unpredictable.
Jim Breuer could be SEI
