For me, no my personality has not been influenced by culture.
I'm white british so I don't have much of a cultural background, but my personality, my beliefs, my way of living is very different to to my family and my peers. I'm an INTP and I'm autistic so take that as you will.
I think the fact that I'm autistic explains why my personality hasn't been shaped as much by my background as much as my peers. I see things very logically, I don't care for traditions or religious beliefs. I do have spiritual beliefs, I practice witchcraft - but it's in a very non traditional way because again I don't care for traditions. Nobody in my family or really where I live believes or thinks the same way I do, I used to hate that fact but I have grown to quite like that about myself.
My personality has been influenced by trauma and mental illness however, I feel because of what I've been through the way that I act around others has drastically changed over the years. I used to be very hostile towards anyone I didn't know because I was afraid of being hurt, nowadays I'm the opposite, I try my best to be friendly and understanding and have grown to love human connection. But I'm growing up, things change as you get older so I don't know.
I think I'm just waffling at this point haha
