I'll find this later, but Jennifer said that in a relationship she's at first guarded and reserved (which also made me think of her being introverted).
I see where you're coming from, but I still think she is iNtuitive. She has talked about her intuition helping her act in other interviews before (like this
one). And grr, I can't find those scans of her talking about her "big picture" view on life. I'll keep looking for them. I found this quote however:
That seems rather N-y to me, her believing that she will know more in the future than she does now. I recall some other moments of her musing about her future in interviews. Like, once in an article, she was wondering what kind of person she was going to be in the future -- like she was worried she was going to turn into some crazy brainwashed actor like many others have in Hollywood. And in another interview once, she said that before the Hunger Games came along, she'd imagined herself to do a string of indie movies more and then settle down once she hit thirty or so to have a family (if I remember correctly).
I feel like the fact she calls Winter's Bone
a "beautiful" movie also points towards her being N. I just forced my ISFJ mother and ESFP brother to watch it, and they both hated it and called it stupid. It is a rather unorthodox movie, but I believe that it's beautiful, backwardly.
There's also another quote I remember of Jennifer calling this scene she had in The Burning Plain in which she and her boyfriend lay in their parents' bed in their parents' clothing (I think -- I haven't seen that movie in a while) "sick and poetic." I feel like a Sensor might on impulse call it just "sick."
I don't know if this is related to S or N, but I was reading more of her articles, and Jennifer talks about fate a few times. Here's a quote:
Also, I feel like the fact that fame scares her attests to her introversion.... I could be wrong, but isn't such a desire for privacy an attribute of introversion? Hmm. In her Marie Claire interview, she says how she always wanted to be the center of attention as a kid, which threw me off for a second. But then I thought about it more, and I realized I always obnoxiously wanted to be the center of attention as a kid, too, and yet at the same time, it was easy for me to be alone.
I'm not 100% sure, but I'm pretty convinced that Jennifer is an INFP who seems like an ENFP or ESFP in public. There are lots of introverts who seem extroverted around other people (myself included -- actually, I'd say most people who are acquainted with me think I'm an ENFJ or ESFJ). My brother is an ESFP, along with one of my closest friends -- I feel like I would know it if Jennifer were one as well, you know? But who knows.
