““The pattern of movement in the supermarket is counterclockwise in the United States, but PathTracker® studies in the UK, Australia, and Japan show a much greater tendency for shoppers to move in a clockwise pattern there. This could be due to many factors, including more crowded stores, but it could indicate that while there could be biological or instinctual forces that drive this behavior (such as the dominance of right-handedness), traffic patterns in the store may also be affected by vehicle traffic patterns outside. In these small studies, we noted that in countries with right-hand driving, where traffic circles move in a clockwise pattern, shoppers in stores may be more comfortable moving the same direction. Like the Coriolis Effect in physics, where winds and currents tend to veer to the right in the northern hemisphere and to the left in the southern hemisphere, the movement of shoppers in a store may depend, in part, on where in the world you are located.””
