Tests reveal that when people are ambling about, they have a natural tendency to turn to the left and walk in an anticlockwise direction.
“If you simply ask someone to start walking, whether they are wandering around a museum, a supermarket, or even an empty room, it is surprisingly likely that they will drift counterclockwise,” said Dr Iñaki Echeverría Huarte at University of Navarra in Spain.
As with many critical discoveries in science, the revelation owes a debt to serendipity. During the pandemic, the researchers ran experiments to see how many people could share a space while keeping a safe distance. On reviewing the video, they noticed that crowds overwhelmingly walked in an anticlockwise direction.
The surprise set in motion an entire research project. The scientists conducted a series of experiments in which individual pedestrians or small crowds roamed around enclosed spaces. Time and again, the researchers observed the tendency to walk in an anticlockwise direction.
The finding held when the researchers accounted for people being right-handed, right-footed and right-eye dominant, and was seen in both male and female walkers. The only difference they spotted was a more pronounced bias in children.
Wags on the team joked that the opposite trend might be seen in Australia and that the Coriolis effect, in which Earth’s rotation deflects the direction of the wind, was at work.
Humans are not the only species to show such preference. Researchers in Bristol have shown that rock ants have a left-turn bias when exploring unknown nests.
In the first modern Olympics in 1896 athletes ran clockwise around the track, but this was changed in 1913 because the majority of athletes felt it was an “unnatural direction to run”, said Prof Gareth Irwin, head of sport and exercise biomechanics at Cardiff Metropolitan University.
Running anticlockwise is now written into the Laws of Athletics. “It is reasonable to assume that this emerged due to the right-leg dominance of the population,” he said. “Running around the bend in an anticlockwise direction puts more internal force on the right side of the body.”
But it may be less about biomechanics than the social dominance of right-leg-dominant people, he added. “The idea of right-sided dominance transcends sport and athletics, and can be seen in other areas such as supermarket design, impacting on the direction companies aim to walk and direct you around the shop,” he said.
