So, some researchers did a study and found out that there is a gene that predisposes people towards a “liberal” political stance. James Fowler, the lead researcher, said:

“The way openness is measured, it’s really about receptivity to different lifestyles, for example, or different norms or customs… we hypothesize that individuals with a genetic predisposition toward seeking out new experiences will tend to be more liberal.” 

This is kind of what I mean when I talk about Cosmopolitan thought vs. Nationalist thought. As I said here: “nationalism places far higher importance upon symbols and traditions than does… cosmopolitanism.” So, Liberalism, or what I call “Cosmopolitanism”, is much more willing to experiment with different customs, symbols and societal norms.

Interestingly, however, I am politically what people consider a “Liberal” on most issues, yet I don’t particularly enjoy “seeking out new experiences” in my personal life. I very much enjoy having a routine and sticking to it.
