Tycho:
In case anyone wants to read the <a href="http://www.cell.com/current-biology/pdfExtended/S0960-9822(14)01213-5">actual article</a>.
Thanks for this. After reading through some of it there are some intriguing points, but this one jumped out at me.
quote:
Our results are consistent with the idea that political beliefs are connected to neurobiological composition. But both genetics and life history play an important role in establishing both connections between neuroanatomical regions and the propensity for these regions to respond to environmental stimuli. We have not isolated the distinct roles played by genetics and life history in the development of the brain responses that we measured.
So, in other words, they don't really have enough information to say whether it's nature or nuture that is the driving force behind this (or both!), but just that there's some funky stuff happening in the brain that can be used to reasonable predict political leanings.
There are 2 other studies in the footnotes that discuss genetics and political leaning. Does anyone know how I can find out if they are available for reading?
