Ever tried walking in a straight line with your eyes closed? How long did it take until you unknowingly veered into oncoming traffic?
Probably not very long, according to Asa Schaeffer
(and this amazing animation
illustrating the phenomenon). Schaeffer recently conducted an experiment where he sent several blind-folded people off in different barren locations and told them to walk in a straight line for an hour. He found that participants slipped into circles when they didn’t have an external focal point, like a mountain top or the sun.
“Walking in circles” when you’re lost has more than a grain of truth to it, after all.
