Racist people in the U.S. appear to be clustered along the Appalachian Mountains from Georgia, through New York and all the way up to Vermont, at least according to a Washington Post report Tuesday that cited a recent study published in the scientific journal PLOS One.

And how does one measure something as abstract as racism? This is where technology — in this incidence, Google search — comes in handy. The study used data on how often people searched a racial epithet on the Internet to determine where racists lived.
