Dozens of previous studies have established a strong link between political persuasion and certain personality traits.
Conservatives tend to crave order and structure in their lives, and are more consistent in the way they make decisions. Liberals, by contrast, show a higher tolerance for ambiguity and complexity, and adapt more easily to unexpected circumstances.

The match-up was unmistakable: respondents who had described themselves as liberals showed "significantly greater conflict-related neural activity" when the hypothetical situation called for an unscheduled break in routine.
Conservatives, however, were less flexible, refusing to deviate from old habits "despite signals that this ... should be changed."
