From Physorg.com’s article, Homo politicus: brain function of liberals, conservatives differs: “Using electroencephalographs, which measure neuronal impulses, the researchers examined activity in a part of the brain — the anterior cingulate cortex — that is strongly linked with the self-regulatory process of conflict monitoring. 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.’ Whether that is good or bad, of course, depends on ones perspective: one could interpret the results to mean that liberals are nimble-minded and conservatives rigid and stubborn. Or one could, with equal justice, conclude that wishy-washy liberals dont stick to their guns, while conservatives and steadfast and loyal.”
