Now, 5 and 6 are basically locked in. You might see 5 and 6 swap or 5 swap with one of the top 4 to put him in fourth and that person in fifth.
But basically assume they've hit around the middle of their ability.
And yes, the black haired woman did harp on their credentials a lot. But a lot of them did and then there was the casual racism in putting the clean-cut Asian guy first and classism by putting the military guy last.
All-in-all, Jubilee is trash, as always.
EDIT: And, at the end... Yeah~
If I may blather a bit myself, though, it's interesting to note that the top four are likely within a margin of error. Good day, bad day, their rank is probably malleable. People like 5, IME, are quite intelligent, and I wonder if the circumstances affected their performance (4's too, possibly even 3's). 6... Well, I think that says a lot about where we are as a society. Though that might be the schadenfreude talking.
On the other hand, you could look at the ultimate ranking as one that leans heavily on each individual's confidence and comfort in the situation. 6's oversharing might have been rooted in nervousness and a sense of inferiority (the kind that might drive someone to, say, a push for high levels of formal accomplishment). Whereas, as someone in the comments pointed out, 3 was calm and relaxed even as they were being told that they were definitely the dumbest person in the room repeatedly. 1 is tall, male, stereotyped as intelligent, academically-accomplished, and acknowledged as such by everyone else; he had the best situational advantage for his headspace, entering the test.
