A study out of Rice University was performed to see if there was a correlation between people’s psychological traits and their political attitudes. The study was over 46 adults chosen randomly in Lincoln Neb. They probed the adults with stimuli of horrific pictures and startling sounds to see how they would respond and then compare that to their political views on torture or other matters of foreign policy. “Those individuals with measurably lower physical sensitivities to sudden noises and threatening visual images were more likely to support foreign aid, liberal immigration policies, pacifism and gun control, whereas individuals displaying measurably higher physiological reactions to those same stimuli were more likely to favor defense spending, capital punishment, patriotism and the Iraq War,"
