Have you ever heard the old saying that people who get lost tend to walk in circles?
Jan L. Souman, a German psychologist, wanted to determine scientifically if this was true. He took participants of an experiment to a large forest area and to the Sahara desert and used a global positioning system to track where they went. They had no compass or any other device. Instructions to them were simple: walk in a straight line in the direction indicated.
Dr. Souman later described what happened. “[Some] of them walked on a cloudy day, with the sun hidden behind the clouds [and with no reference points in view]. … [They] all walked in circles, with [several] of them repeatedly crossing their own path without noticing it.” Other participants walked while the sun was shining, with faraway reference points in view. “These … followed an almost perfectly straight course.”
