Comment Structural? (Score 4, Insightful) 758
It's not hardwired: If it were, we'd be able to do these scans at birth or an early age and find similar patterns. But we don't. Which means the brain's structure changes in order to specialize in certain thought and behavior patterns. The fact that this applies to politics as well as, say, geospatial, tasks, should be absolutely no surprise.
It's disengenuous to suggest these things are hard-wired because they imply they cannot be changed. Except they can: I've known many people who, after experiencing a significant emotional event, altered their politics, religious affiliation, and even base personality traits. The human brain is exceptionally malleable. This study only offers a snapshot at a particular point in time and suggests that if certain structural properties are present, the thinking pattern is likely to be of a certain type. It does not say whether that structure was present before, after, or the extent to which it can be changed, and if so, how quickly.
It's like taking a photograph of a car driving down the road and assuming that it's on that road, and only that road, forever.
