Sometimes it seems like conservatives are afraid of everything. But don't blame them—they're born that way, poor things:

A study to be published next year at University College London suggests that conservative brains are structured differently than the brains of other people.... Specifically, the research shows that people with conservative tendencies have a larger amygdala and a smaller anterior cingulate than other people. The amygdala—typically thought of as the "primitive brain"—is responsible for reflexive impulses, like fear. The anterior cingulate is thought to be responsible for courage and optimism. This one-two punch could be responsible for many of the anecdotal claims that conservatives "think differently" from others.
