Study Finds Humans Naturally Prefer Walking Left in Anticlockwise Direction
A new study by researchers from the University of Navarra in Spain and the University of Tokyo in Japan reveals that humans have a natural tendency to walk left, moving in an anticlockwise direction. This pattern was consistently observed across 32 out of 33 experiments involving participants of various ages, in different countries, and in diverse settings including open spaces, confined areas, groups, and individuals walking alone. The research was published in Nature Communications.
The experiments included overhead drone footage of people moving freely in schoolyards and controlled indoor environments. Even when participants walked alone without external influences such as crowds or directional cues, they still showed a gradual preference for turning left. This tendency was especially strong among young children around five years old, who naturally organized their movement in a shared anticlockwise direction during free play.
Interestingly, participants generally believed others would move clockwise, indicating a disconnect between perceived and actual behavior. The researchers explored possible explanations such as eye dominance and biomechanical asymmetries but found these factors insufficient to fully explain the phenomenon. Larger scale influences like Earth's rotation or magnetic fields were also considered unlikely.
The study notes that similar directional preferences appear in certain animals, including fish, newts, ants, and parrots, suggesting a broader biological basis. Beyond scientific curiosity, these findings could have practical applications in designing public spaces such as malls, airports, stadiums, and parks to better accommodate natural human movement patterns and improve crowd flow.
The researchers also highlighted that many running tracks and racecourses traditionally run anticlockwise, though the reasons remain unclear. Ultimately, the study suggests that even when people think they choose their walking direction freely, their bodies may subtly guide them leftward by default.
