The political left rolls with the good and the political right confronts the bad: connecting physiology and cognition to preferences
Dodd, et. al., Phil. Trans. R. Soc. B 5 March 2012 vol. 367 no. 1589 640-649.
... the central message of these findings is not that one political orientation is somehow superior to the other but rather that, in light of the connection between location on the political spectrum and physio-cognitive differences, those on the political right and those on the political left may simply experience the world differently. It is probably because of these differences that some on the right view those on the left as hedonists who ignore pressing issues while some on the left view those on the right as doomsayers who obsess over constructed threats and problems.
