The article linked to a scientific article, but I wanted to see if I could find a test that incorporates this trait, and I found one. Interestingly, it also breaks down each score into sub-scores. It's also apparently based on cross-cultural studies.
Annoyingly, while you can dowload a PDF of your results it doesn't show the convenient pictures that show you whether you're within the bounds of normal or not, and I know most of you don't have the patience for that. (One thing this test highlights is that I'm weirdly patient.) So I had to screenshot stuff. And as my results should make clear, I'm far out of bounds for many of these.
Spoilered for length
The honesty-humility score turns out to be a bit of a wash. I'm often willing to break rules if I don't think I'll get caught (though generally only in cases where the crime is either victimless or the effects are spread over a large number of people), and I don't like conspicuous displays of wealth. And despite the fact that it seems like the first is dishonest and the second is humble, they somehow balance each other out. I score high on sincerity but within normal bounds and score almost exactly average on modesty.
However I find some of my other scores a bit more interesting. The only scores that are close to how I usually score on OCEAN tests is openness to new experiences, where I still score way out of normal bounds, and agreeableness, where I'm just below acceptable lower limits.
Meanwhile I score lower on neuroticism (emotionality) and higher on conscientiousness than I've ever scored on an OCEAN test. Typically I score low on the latter and extremely high on the former, but here I'm well within normal bounds for both. I also score much lower on extraversion than most tests. All of these seem to be because each factor is broken out into equally-weighted sub-categories.
Introversion-extroversion is clearly more accurate than typical OCEAN tests. I'm a talkative introvert, and though they don't ask about how much I talk to people at all, I guess that "boldness" reflects my willingness to talk to strangers. However I am otherwise exceptionally introverted.
Conscientiousness is interesting, since it suggests that despite being disorganized, since I'm cautious perfectionist I end up near the middle of the road. I think that the test overstates how dilligent I am and that should be lower though.
My neuroticism/emotionality score is dragged down because despite being an anxious and apparently dependent wreck of a human being, I have little regard for my physical safety and am apparently a robot about feelings. As such, it would appear that my neuroses balance out and produce a fairly well-rounded human being.
My agreeableness sub-scores are interesting, despite being consistent with OCEAN tests. I realized recently that I'm an incredibly patient person, which this test bears out. I'm not entirely sure how that happened, since I used to be incredibly impatient. However I'm still incredibly blunt with people (which isn't part of the honesty-humility scale), as well as stubborn and prone to holding grudges, which are apparently two distinct sub-scales.
Also, altruism seems to be its own thing not part of any larger factor, and I seem to be just at the lower bounds of normal. Hooray for me not being as selfish as I thought I am, I guess?
Any rate, if any of you have the patience to take this test and screenshots of it I'd like to see your results and maybe self-analysis.
