Recent discussions surrounding the human tendency to turn left and walk anticlockwise have been met with a fascinating historical counterpoint. While contemporary reports have suggested a lack of definitive understanding on this phenomenon, correspondence published in The Guardian points to extensive 19th-century research by French physiologist Professor Raphaël Dubois, who proposed a compelling explanation rooted in the Earth's rotation.
Professor Dubois, a prominent figure in physiology, identified what he termed the “antikinetic gyratory movement.” He theorised that this movement, observed in the natural world, was a direct consequence of the Earth's continuous rotation on its axis. His work predates much of modern behavioural science, offering a unique perspective on ingrained human and animal patterns.
A notable observation made by Dubois occurred during the 1900 Universal Exhibition in Paris. He meticulously documented a clear preference among exhibition visitors to navigate the grounds in an anticlockwise direction. This real-world observation provided empirical support for his theoretical framework, linking a fundamental physical force to human behaviour on a large scale.
The implications of Dubois's theory extended beyond mere pedestrian movement. In the years leading up to the First World War, he ambitiously applied his concept to explain broader patterns of migration, encompassing both human populations and animal species. Furthermore, historical documentation, including an article in the journal Peace & Change from 1986, confirms that Dubois even attempted to connect his theory of antikinetic gyratory movement to the origins and dynamics of warfare.
This historical perspective from Professor Dubois, brought to light by Dr Peter van den Dungen of Lightcliffe, West Yorkshire, Ian Henderson of Nottingham, Patrick Billingham of Brighton, and Gail Hebert of Tenterden, Kent, suggests that the left-turn bias observed in humans might not be an entirely unknown phenomenon. Instead, it could be a long-recognised aspect of our interaction with the planet's fundamental physical properties, offering a rich historical context to ongoing scientific inquiry into human spatial navigation and behavioural preferences.
