This is the personality test I took: https://www.16personalities.com/free-personality-test
It's super easy, quick and it tells you a lot about yourself. It also tells you the people you share personalities (the Architect, in my case) with.

Professor Moriarty "Architects like to win and dislike acting solely on emotion, and this can make it seem [like they act coldly] to other types who don't understand them well."

Petyr Baelish ("Littlefinger") "Architect personalities can carry their confidence too far. They may falsely believe that they've fixed all the issues of the matter, then call it a day, rejecting the opposing opinions of those they believe to be intellectually inferior."

Jay Gatsby "People with the Architect personality type may never be very comfortable sharing their feelings, and they may spend more time thinking about love than expressing it."

Katniss Everdeen "[Architects] have a great dislike for authority figures who go around forcing others to obey laws and rules without understanding the purpose of the standards themselves. Architects are likely not to get along with anyone who prefers how things "have always been."

Tywin Lannister "Architect parents aren't prone to give as much warmth as the classic images of parenting suggest they should. They are often insensitive and not prone to displays of affection."

Michelle Obama "If something grabs their interest, Architect personalities can be very dedicated to their work. They often put in long hours and intense effort. Architects are goal-oriented and if tasks lead to something clear and relevant, they strive to accomplish those tasks."

These are only some of the ones I resonated with the most.
