This is the sort of thing I love learning about. It's like when you first learn about latent opinions, and realize most polls are almost meaningless. There are these major flaws in thinking that persist in popular culture and academia, and they are fascinating. A good find and thanks for sharing.
That was an interesting (and weird hah) read. For anyone who has lived in a different culture for any length of time, it seems pretty obvious how lots of ideas are shaped by culture and upbringing. I had no idea though how deeply embedded into research those ideas were though. The thing that surprised me the most though was the visual perception. I vaguely remember an experiment on animals showing those raised in a place with mostly vertical lines had trouble or perceiving horizontal lines.
I agree! For me, "men raised in the honor culture of the American South have been shown to experience much larger surges of testosterone after insults than do Northerners," hit really close to home. As a son of the south, I now have something to blame my ornery temperament on. It's just all the extra testosterone flowing.
