Whether you’re pacing while on the phone or wandering around a park, chances are you’re unconsciously turning in the same direction as almost everyone else.
That’s because scientists have discovered that humans have a natural tendency to move counterclockwise.
This surprising bias persists across different countries, age groups and even when people are walking completely alone.
And it suggests the instinctive desire to turn left is an innate feature of human movement rather than a learned behaviour.
‘Our findings are highly consistent,’ the team, from the University of Navarra, wrote in the journal Nature Communications.
‘Regardless of crowd size, boundary effects or laterality traits such as handedness, footedness and eye dominance, counterclockwise motion systematically emerges.
‘Our results indicate that this symmetry-breaking phenomenon is fundamentally rooted in individual locomotor tendencies.’
They said their findings could have implications for the design of stadiums, museums, airports and shopping centres – as anti-clockwise circulation paths could ‘improve comfort’ for visitors.

This surprising bias persists across different countries, age groups and even when people are walking completely alone
For their study, the team carried out a series of experiments involving hundreds of people in Spain and Japan.
They asked participants to walk freely in circular enclosures, open spaces and, in one test, entirely on their own while overhead cameras or drones tracked their movement.
The researchers also observed schoolchildren in a playground, analysed existing footage of preschoolers and surveyed university students about which direction they expected people to walk.
Analysis revealed people consistently moved in a counterclockwise direction, regardless of whether they were walking in crowded groups or entirely alone.
The tendency also persisted among left-handed people, participants who naturally preferred turning right, and volunteers in Japan, where pedestrians typically avoid oncoming people by moving to the left rather than the right.
Some of the strongest evidence came from experiments in which more than 200 people were asked to walk alone inside an enclosed space.
Even without anyone else to follow or avoid, participants still showed a statistically significant tendency to drift counterclockwise, suggesting the effect originates in individual movement rather than crowd behaviour.
The tendency was even stronger among nursery school children aged around five. During free-running games, almost the entire group naturally fell into a coordinated counterclockwise pattern, suggesting the behaviour develops very early in life and is unlikely to be driven solely by learned adult habits.
The researchers speculate that subtle neurological or biological asymmetries may influence the way we move
Surprisingly when asked which direction they thought others would walk, most participants said clockwise.
Exactly why humans favour the left, however, remains a mystery.
The researchers speculate that subtle neurological or biological asymmetries may influence the way we move.
They said that vortex-like behaviours have been reported in schools of fish, tadpoles and ants.
‘Temnothorax ants display a marked tendency to turn left while exploring and flying budgerigars exhibit lateral preferences when choosing equivalent apertures during route choice,’ they wrote.
‘Overall, the implications of our findings are significant. By demonstrating that individual biases–rather than collective effects–drive the observed CCW motion in pedestrian roaming, our study deepens our understanding of pedestrian dynamics and provides a new lens for studying crowd behaviour.’
