Generally you have to look for non-traditionalism (by today's standards) in terms of elementary/high school education, elementary/high school hobbies/activities, etc. This used to be the norm but not so much now.
Most Americans are raised and educated to be compliant and submissive, which is the kiss of death to "giving a shit" about anything. You have to be willing to take risks and rock the boat to have interesting and relevant opinions and interests. Too many won't do that.
Most of the people I've found who "give a shit" tend to have strong moral/religious training while young, tend to be home-schooled, tend to have had fairly intense nerd hobbies in their youth, tend to have been raised by parents to lead and/or decide what is right on their own compass or by critical thinking rather than by others.
In general they did NOT go to public schools, NOT live without religion in their youth, NOT go to top tier universities (especially not Ivies or West Coast Ivies), NOT tend to go along with the crowd for morality or ethics or otherwise demonstrate NPC-traits.
The top people who work for me were non-traditional in one or more of the above ways. Some didn't even graduate with university degrees but have a passion for everything they do in an autodidactic way.
Sadly most people I get unrequested resumes from or interview are pretty close to being dead inside - NPCs. To avoid this, I usually go to where the right people congregate, talk with them, and also just watch how they approach everything around them. Better if in-person but online works sometimes. I've gotten pretty good at reading the NPCs from the non-NPCs.
