A five-year study has revealed that humans, similar to certain animals, have an innate tendency to turn left when walking, even in the absence of external influences.

• The anticlockwise turning bias was observed in over 200 volunteers walking alone in an empty arena.
• Researchers at the Universidad de Navarra, including Assistant Professor Iñaki Echeverría Huarte and Professors Ángel Garcimartín Montero and Iker Zuriguel Ballaz, led the investigation.
• The cause of this individual bias remains unknown, with no link found to handedness, dominant foot, or eye, suggesting a potentially deeper biomechanical or neurological origin.
