The political left rolls with the good and the political right confronts the bad: connecting physiology and cognition to preferences. Phil. Trans. R. Soc. B 5 March 2012 vol. 367 no. 1589 640 – 649.

The study by Dodd et al. (2012) examined the relationship between political orientation, cognitive processing, and physiological response to positive and negative stimuli.

The researchers found that political orientation was associated with differences in the cognitive processing of positive and negative stimuli. Liberal individuals showed a stronger preference for new and positive stimuli and a higher willingness to take risks. Conservative individuals, on the other hand, preferred more familiar and conservative stimuli and showed greater responsiveness to threats and negative events.

These differences in cognitive stimulus processing were also associated with physiological responses. Liberal individuals showed higher activity of the brain's "reward system" in response to positive stimuli, while conservative individuals showed higher activity of the brain's "threat system" in response to negative stimuli.

The results suggest that political beliefs may be related to differences in stimulus processing and physiological responses, which may be due to specific cognitive and neural processes.
