In 1968 a debate was held between conservative thinker William F. Buckley, Jr., and liberal writer Gore Vidal. The story of the 1968 debate opens a well-regarded 2013 book called Predisposed, which introduced the general public to the field of political neuroscience. There is also an unresolved chicken-and-egg problem: Do brains start out processing the world differently or do they become increasingly different as our politics evolve? But some statements were surprising, such as a conservative expressing a pro-choice position or a liberal arguing for invading Iran. It will be nearly impossible to lessen the partisan influences before the November 3 election because the volume of political information will only increase, reminding us of our political identities daily.
