White Suburban American speaking.
I can honestly say I felt the most pressure from overall society to be 3ish (professionally speaking). Everything has to "look good", shine that resume up, "fake it till ya make it", wear the right clothes, look professional, show confidence, etc. Almost with a 7ish cast--be bubbly, upbeat, and outgoing or you're not acceptable. POSITIVE THINKING. Always remember to smile, why are you not smiling? No one wants to hear it, no negativity allowed. Take your meds and get back on the assembly line. I can deal with the first part, but the second part makes me want to start hitting people.
I also feel there's a lot of 6ness in American culture--the sky is always falling. There's always some cataclysmic event coming our way--an overarching terrorist enemy that will wipe us off the map, the end of social security, the national debt, TV is giving kids cancer, Video Games are ruining our youth, climate change means it's the end, etc etc etc. It's like we constantly feel that we're on the brink total annihilation or something. It was a real shift when I began living outside the country and saw that other cultures took these concerns and dealt with them efficiently while maintaining a hopeful outlook on their ability to create a better future. So, I acknowledge that my mind was biased that way as well.
Ftr, as a girl, I felt no pressure to be more 2ish whatsoever.
In my own family...everyone in the immediate family is a sp9 (or 9-fixed), and that's what I was inculcated with there, perhaps more deeply. I'm probably triple reactive, and you can see why I had trouble both living with my family as well as figuring out my core type. They basically did everything in their power to undermine my natural tendencies, suppress my expression, and deny my fire; with the end result that I became a withdrawn, apathetic, disempowered adult that didn't know I was supposed to go out and have fun when I was young. I still bear great antipathy towards them.
