Mass and activity of brain structures correlate with political perspectives

Brain imaging research indicates some aspects of individual political orientation correlate significantly with the mass and activity of particular brain structures including the right amygdala and the insula. This correlation may derive in part from genetics, but is also influenced by environment and behavior.

“there’s a critical nuance here. Schreiber thinks the current research suggests not only that having a particular brain influences your political views, but also that having a particular political view influences and changes your brain. The causal arrow seems likely to run in both directions—which would make sense in light of what we know about the plasticity of the brain. Simply by living our lives, we change our brains. Our political affiliations, and the lifestyles that go along with them, probably condition many such changes.”

Thanks to member, Edward, for recommending this article: http://www.motherjones.com/politics/2013/02/brain-difference-democrats-republicans 

In a similar vein, Bob Altemeyer conducted and reported on some seminal social science research and theory on political dispositions. See http://home.cc.umanitoba.ca/~altemey/. Note the free book link on the left.

“When something is memorable, it tends to be the thing you think of first, and then it has an outsize influence on your understanding of the world. After the movie Jaws came out, a generation of people was afraid to swim in the sea—not because shark attacks were more likely but because all those movie viewers could more readily imagine them.”

Immigrants are less crime prone that native-born Americans

I don’t find a lot of common ground with the libertarian Cato Institute, but I salute their honest reporting of research findings on immigrant-committed versus home-grown American crime:

“Both the Census-data driven studies and macro-level studies find that immigrants are less crime-prone than natives with some small potential exceptions.”
