The "Big Five" test is hilarious. It groups things into one trait where I am strongly half and strongly half. If the trait were broken cleanly into two, I would be toward the far ends of each, but since they're together I'm 50%.
Open-Mindedness: 98 - I said I really like art.
Conscientiousnes: 56 - I said I was pretty messy but very reliable. However, I'mm actually very messy (in private spaces and in personal projects) and very reliable and organized (in interpersonal relationships and important projects/at work).
Extraversion: 48 - I don't like spending a lot of time with people, and I prefer small groups, so I'm definitely an introvert, but among friends I'm very talkative, sociable, and friendly. It's clearly two entirely different categories bunched into one. Additionally, since I have a balance of private time and social time, it fits that my conscientiousness would be split between those two time periods, as well.
Agreeableness: 40 - I am generally good natured, relaxed, and courteous, but I also answered that I have 0 belief in forgiveness (I think change is important, not forgiveness) and I have a low general opinion of people (critical) so I scored lower, but I think it's more like 2 different questions: I'm agreeable to people I feel deserve it, and have a deep disdain for people that are awful. Again, seems like two different questions.
Negative Emotionality: 11 - I'm chill. Even when I have a deep disdain, I don't let it bother me. I just avoid those people, or casually enjoy brutalizing them with sarcasm. See: Agreeableness above.
Seems like a poorly defined test, to me.
