I took open source test on openpsychometrics.org with 50 questions on 2026-01-10. My results:

Agreeableness - Low (26 percentile)
Conscientiousness - Very High (95 percentile)
Opennes to Experience - Very High (93 percentile)
MBTI
I'm INTJ
I'm aware MBTI has low test-retest validity, and have heard anecdotes of people's results changing on retests. However I have consistently scored INTJ for many years.
I don't think I saved the detailed breakdown anywhere, and can't be bothered with retesting

Self-diagnosed - I am good at Technical. I am average at Design [2]. I mostly suck at Physical [1]. I absolutely suck at Management.
notes
[1] My take here is you can get pretty good at Physical skills via brute force repetitive practice even if you lack talent. It is basically just muscle memory of ankles and wrists, plus general muscular strength + cardio + endurance. I play drums well for example, I don't think this means I am good at Physical, I just think it means I have put in the hours.
[2] I am not clear around the exact boundaries between Design And Management. "Understanding your target user's needs" is like one of the most valuable skills out there, and it is not fully clear to me if this is just a Design skill or if it also has Management aspects.
Jonathan Haidt moral foundations test
I took this way back but didn't save the result.
Magic the Gathering colour wheel
What do I most want out of my life?
Self diagnosed - Knowledge > Power > Freedom >> Community > Acceptingness. If you're into this stuff, I am Blue and Black on the MtG colour wheel, with a hint of Red I have suppressed in favour of Black.
There is definitely strong correlation between MtG colour wheel and Harry Potter houses. I am Ravenclaw (MtG Blue) and Slytherin (MtG Black) basically
