Humans Prefer Anticlockwise Walking, Study Finds

Core Finding: Anticlockwise Walking Bias
When asked to start walking in varied indoor settings—museums, supermarkets, or empty rooms—participants frequently drifted counter-clockwise. The tendency was observed consistently across trials.
Background
The project began during the COVID-19 pandemic to test social distancing in confined spaces. Initial single-pedestrian tests expanded to small crowds in enclosed rooms. Replication in Japan produced the same left-turn bias.
Key Figures
The study was led by Dr Iñaki Echeverría Huarte (University of Navarra, Spain) with Dr Claudio Feliciani (University of Tokyo) as co-author. Prof Gareth Irwin (Cardiff Metropolitan University) contributed sport-related commentary.
Data
The bias appeared regardless of handedness, footedness, eye dominance, and gender, and was stronger in children. Similar left-turn preferences have been recorded in rock ants exploring new nests.
Criticism & Opposition
Researchers propose two main mechanisms. One attributes the bias to subtle anatomical asymmetry, suggesting imperfect bodily symmetry nudges walkers leftward. Another emphasizes cultural or social dominance of right-leg-preferring individuals, especially in sport and retail layout. A joke about the Coriolis effect was mentioned but lacks empirical support.
Impact
Understanding the bias can refine crowd-flow models for evacuation planning and guide architectural design of public venues, from museums to train stations. The bias also explains the 1913 shift to anticlockwise running in Olympic tracks, possibly reflecting right-leg dominance.
Official Statements
Echeverría Huarte noted the bias persists across demographics but its cause remains unresolved, highlighting a stronger effect in children. Feliciani said that identifying the mechanism could deepen knowledge of human perception. Irwin argued that right-leg dominance offers a plausible biomechanical basis while acknowledging possible sociocultural factors.
Quotes
- “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.” — Dr Iñaki Echeverría Huarte, University of Navarra
- “Each of us carries a small personal bias to turn slightly to one side, and when many people share a space, those tiny biases add up into a net counterclockwise rotation.” — Dr Iñaki Echeverría Huarte, University of Navarra
- “We don’t know why it happens, but we think that by understanding the reasons, we could better understand how we perceive the world.” — Dr Claudio Feliciani, University of Tokyo
- “It is reasonable to assume that this emerged due to the right-leg dominance of the population.” — Prof Gareth Irwin, Cardiff Metropolitan University
Next Steps
The team is running virtual-reality simulations and trials where participants walk with a simulated broken leg, aiming to isolate sensory-motor factors behind the left-turn bias.
