"Vivid images and memories of these images are used to make judgments about the overall likelihood of dangerous events." says Robert Kraft, a psychology professor at Otterbein University. In fact, "these horrific events are no more likely today than they were yesterday or 10 years ago."
Says David Schanzer, a Duke University professor who directs the Triangle Center on Terrorism and Homeland Security: "Since 9/11, you are far more likely to drown in your bathtub than be killed by terrorists in the United States."...Maybe so, but neither your bathtub nor your bathwater are intent on conquering the globe for Allah. And if you do nothing to confront existential threats du jour, you can be bloody well sure that they'll come back to haunt you; heck, they may even kill you.
