Wray Herbert writes in a Scientific American article titled "Border Bias and Our Perception of Risk" of a study by husband-and-wife team Arul and Himanshu Mishra at the University of Utah on how people perceive events within a bias of arbitrary political borders. Asked to imagine a vacation home in either "North Mountain Resort, Washington, or in West Mountain Resort, Oregon" the study group was given details about a hypothetical seismic event striking a distance that vacation home, but details differing as to where the event occurred:

Some heard that the earthquake had hit Wells, Wash., 200 miles from both vacation home sites. Others heard that the earthquake had struck Wells, Ore., also 200 miles from both home locations. They were warned of continuing seismic activity, and they were also given maps showing the locations of both home sites and the earthquake, to help them make their choice of vacation homes.

The results revealed a bias in that people felt a greater risk when the event was in-state as opposed to out of state. A second study involved a not-in-my-backyard look at a radioactive waste storage site and the Mishras used maps with thick lines and thin dotted lines to help people visualize the distances and state borders. It isn't hard to guess which lines conveyed a greater feeling of risk. I recall a story my brother told me about 17 years ago in which he was helping an old friend change the oil in his farm tractor. My brother asked, "Hey, Jack, where do you want me to put this [the used oil]?" Jack said, "Pour it over there on the stone wall." (We lived in Connecticut, where they grow those things everywhere). Brother Marshall said, "Jack, you can't do that anymore." Jack thought a short second or two, and said, "Yeah, you're right. Better pour it on the other side."
