The guy from the Asura Psyche channel on YouTube tested as VLEF from the Attitudinal Psyche website if you want an example of what that looks like. He's INTJ in MBTI. I don't think he's done a deep dive into the psychosophy system, but VLEF does seem to fit him pretty well. He clearly likes to lecture and teach.
I think I'm 3L, and will feel slightly alarmed if I don't think I know the answer or if I don't feel we've landed on the absolute truth. 2L can help me calm down mentally and not lose sleep because they almost treat it like a game, although that has its downsides as well. In some of our interactions the 2L person almost started to feel a sense of responsibility towards me, like to reassure me and not tease me too much. Still not above toying with someone's brain, though, and others like 1L were fair game to their trolling
There's a section on that website about Accentuations that details how 4F can differ depending on the person. I relate to you somewhat. Adulthood and having higher Volition probably also help naturally care for Physics more if you have the desire. You can make it into a goal for yourself and have follow-through.One thing that seemed somewhat off was 4F as while I don't care about food or comforts and whatnot I was actively involved in sports when younger, and enjoy physical activity, and I want to be strong and healthy. So, that isn't completely neglected in me. Also the part in 1V "myths and truths" that says they do not feel guilty about their mistakes - well, I do. I looked at other types and compared, but came back in the end to VLEF as the best overall fit.
Having 3E could be what gives you guilt over mistakes if it involves hurting other people or relationships, maybe.
