Mary-Kate Olsen

Se sticks with the object while Ne bypasses the object to get to its associations and possibilities. Of course, either way, the function would be a bit muted in Mark-Kate Olsen as a result of it being her auxiliary (and her not repressing Si/Ni). But where is the evidence of Ne? Based on all the interviews I've watched of her, she was not associative, tangential, or anything you would expect of an NP type. She was far more down-to-earth and grounded than an INFP. She didn't speak about the abstract (N) so much as the concrete (S), and wasn't intellectual nor was she concerned in finding 'escape' from physical world, but rather was oriented with reality and being 'in the world.' She's not someone who connected the dots in a associative way, and if she really did, then it rarely made way in her manner of communication.

I know I'm mostly focusing on general trends of conscious flow rather than presenting an exhaustive list of specific examples compared to what I usually do, and that was for 2 reasons. One of them is because I'm lazy at the moment but the other (more important) reason is that ideally the latter comes and naturally falls into place from understanding the former anyway. In a later date, if motivation allows, I might bring up more concrete examples with all the interviews I already watched but for now I just... don't feel like it :)

Regarding the quotes you used in Olsen's page... Now, I know many of the quotes themselves on the site are not meant to be slam-dunk arguments or direct evidence per se (as I'm aware the quotes only come after you concluded on your research), but rather the pieces of data drawn from a context (i.e. interview or book) from which we intuitively fill in the blank a given function-attitude or type vibe. But at the same time, many of your quote pages also have sets of examples illustrating function use in a more direct fashion, and in this guise, some of them represent a kind of aggregate portrait of a particular type (especially the ones that have more quotes). So believe me, I'm not here to argue in bad faith, but I will look at the quotes you made for her INFP page and annotate why they aren't really anymore indicative of INFP than ISFP.

First I will get the obvious out of the way (note that all the quotes I used are from her IDRlabs page, that are actually meant to illustrate INFP above all, so if contradictions against the INFP is found via those quotes, then it is telling to me). Many of the quotes on her page are meant to represent a preference for P over J (comparing her to Ashley), and those specific quotes were never meant to be anything but a showcase of a preference for Pe over Pi/Je (which fits both INFPs and ISFPs). So let's just showcase them now to get it out of the way:

Mary-Kate: "I've never really had much consistency in my life."

Mary-Kate: "[Ashley and I] are very different ... especially when you know us. ... Ashley's more of a Type A personality, I would say."

Mary-Kate: "[Ashley] is more organized than I am."

Ryan O'Connell: "Mary-Kate [is] a free spirit."

Vanessa Hudgens: "[Mary-Kate] is surprisingly very laid-back."

Dirk Standen: "Mary-Kate [is] the ... funnier one."

Adam Cooper: "[In the movie 'New York Minute' where Ashley's character is a straight-A student and Mary-Kate plays a rebellious one] the girls are playing extreme and enhanced versions of themselves."

[Asked about her and Ashley's roles in their clothing line:]

Mary-Kate: "[I'm] more of a creative [person]. I don't worry about making the deals and ... doing the actual deals."

Vogue Magazine: "[As directors of their clothing line] Ashley is often considered as being the financial brain, while Mary-Kate the creative."

Okay so we get the point, Ashley is more J whilst Mary-Kate is more P (not just P but mixture of repressed Te indications too, so I guess IFP, but mostly P). So what about Se vs Ne then based solely on the quotes that are provided in her IDRlabs typing page? Well let's take a look:

Olsen: "I'm not great at communicating my vision - I think I use fragments instead of full sentences. Or when I try to explain ... [it comes out] wrong."

I get it, Ne is generally thought of as scatterbrained. And the intellect of Ne is indeed scattershot in most cases, but another tendency of Ne also happens to be being good at verbal self-expression in real-time (albeit, this applies most to ENPs but INPs, being auxiliary, also fit this). In one of your comments regarding Bob Dylan being ISFP you said (in reply to a comment that posted a link to a interview), "It is ironic that the one interview you highlight above the others had Dylan repeatedly faulting words and verbal expression." As you know, ISFPs tend to find verbal real-time self-expression difficult as a result of the weird Fi-Se-Ni combination. So overall, while the quote itself isn't conclusive, it sounds more ISFP than INFP if I had to choose one.

Mary-Kate: "There are just some really beautiful people in the world. When you're walking down the street, or you're at a restaurant, someone catches your eye because they have their own look. It goes way beyond what they're wearing - into their mannerisms, the way they smile, or just the way they hold themselves."

Now this quote actually sounds more ISFP than INFP to me, it really sounds Fi-Se. She's viewing the world through the lens of their internal sentiments (Fi) and imbuing it to the object, so to speak, but she sticks with the object (being very focused on the clothes, their smile, mannerisms, or whatever) rather than bypassing it to connect it with something else. It's very reminiscent if many of the ISFPs on the site such as Pharrell Williams saying "Sometimes you've just got to put your pride aside and be quiet so that you can absorb not only what a person is saying but how they are saying it - their energy, their body language. It's all for a reason." Contrast Olsen's quote with Brando's (INFP) quote, "I used to sit ... looking out the window at people walking by. I saw them for perhaps two or three seconds before they disappeared. ... In that flick of time I studied their faces, the way they carried their heads and swung their arms; I tried to absorb who they were - their history, their job, whether they were married, troubled or in love." Unlike Olsen, he bypasses the object to uncover or imagine the possibilities.

Olsen: "I think that creating different environments is an art in itself. ... Thinking of someone like Tim Burton and his films - he has had his own singular vision."

I guess this quote is meant to illustrate a preference for INFP-like worldbuilding because Tim Burton was mentioned... I guess? I don't know the context of the quote as "different environments" can apply to both Se and Ne with their general desire for novelty, and in your site's ISFP description it says "ISFPs are still likely to have an extremely well-developed sense of what they like and don't like (indeed, they often have a uniqueness of taste that others tend to envy). For this reason it is especially important for the ISFP that they have the freedom to shape their personal environment as they see fit" so it could fit ISFP too in many respects regarding the "I think that creating different environments is an art in itself" part of the quote.

Mary-Kate: "It's always fun to [become] friends with anyone who has a different profession, a different life, it opens doors. All my friends ... do such different creative things. It's so awesome."

Sounds Ne-ish in showcasing interest in the novelty of others perspectives, so if we're looking at it strictly in terms of Se vs Ne, then sure, it's a bit more Ne on the whole. But in this case, I think it's too little evidence to definitively say it's Ne, not so much as it's "not Ne" so much as "it could be a bunch of other things". It could be the child-like sense of wonder that is often found in Fi types, it could be just P in general as Se too is a out possibilities but just of a more physical nature, etc.

Ashley [to Mary-Kate:] "I remember years ago, when I swatted a fly, you said, 'What if it had a brother or a sister? Do you know how sad the other would be?'"

I know on the surface it sounds Fi+Ne but I think this quote is just high F. I know many typology enthusiasts (not saying you are guilty of this) seem to think that it is only Ne and Fe that thinks of other perspectives, and while this may make some sense in theory, but in practice this doesn't seem to hold true (though Ne and Fe probably are thinking of other perspectives in a more quantitative amount). Fi in general, for example, empathizes by putting themselves into the shoes of another person, imagining themselves as the other person (or animal or whatever) via looking within themselves. The quote (in itself) could also indicate Fe too, but because I agree that she is Fi and not Fe, I'll just brush over that part. From that point of view, the quote just seems to indicate a strong preference for Feeling over Thinking (sentimental and partial over the unsentimental and impartial).

Ryan O'Connell: "Ashley is the smart serious one ... and Mary-Kate is the kooky one."

I get it, Ne is seen as eccentric but it doesn't say much cogntiively about someone if one is described as kooky, it could be Ne, it could also be Ni singular perspectives that reject the physical world, could be Ti idiosyncratic internal logic, could be Fi's following its idiosyncratic sentiments and values, could be Se spontaneity, you get what I mean...

Christopher Bollen: "[Mary-Kate] walks quietly into rooms and gives you her full attention when you talk to her. And you always leave kind of wishing you'd hugged her more."

Both Fi dominants are generally good listeners (so "giving you her full attention when you talk to her" applies to both IFP types) and I guess many individuals who are Fi dominant can be seen as cuddly as a result Fi "live and let live" attitude coupled with their more sentiment-based focus as a result of being Feeling dominant. The "cuddly" part is stereotypical (so not universal by any stretch) but it is something to take into account.
