Mother Jones has published an interesting article suggesting that conservatives and liberals may actually be biologically different.
According to the article, John Hibbing, a political scientist at the University of Nebraska-Lincoln, thinks that humans have, "core preferences for how societies ought to be structured: Some of us are more hierarchical, as opposed to egalitarian; some of us prefer harsher punishments for rule breakers, whereas some of us would be more inclined to forgive; some of us find outsiders or out-groups intriguing and enticing, whereas others find them threatening. Hibbing and his team have even found that preferences on such matters appear to have a genetic basis."
According to Hibbing, we don't fully control our political orientation, any more than we do our sexual orientation or our left-hand/right-hand orientation. Hibbing believes that understanding this promotes political tolerance.
I found the article interesting in how it explains the differences in perception between the political right and left. I hope you do as well.
