You Can't Help Veering Left

You think you're just wandering. You are not just wandering. Researchers have found that roughly 80 percent of people, across countries, ages and cultures, consistently drift left when they walk, tracing a counterclockwise path whether they're in a lab, an open schoolyard or an empty room.

The discovery started with a sideways observation. Applied physicist Iñaki Echeverría-Huarte of the University of Navarra was studying how people maintain personal space while walking when he noticed many participants kept veering left. That spark turned into a five-year research project involving 573 participants across Spain and Japan.

The team tested hypothesis after hypothesis. Spain and Japan have opposite pedestrian norms, so cultural convention was the first thing ruled out. Young children not yet socialized to pedestrian rules showed the same leftward pull. Patching one eye changed little. Dominant hand, dominant foot and sex made no measurable difference.

The leading hypothesis now points to some asymmetry at the biomechanical level, though researchers are candid that they don't yet know what it is. The one factor that produced a slight variation was age: younger participants showed a stronger counterclockwise bias, though the study didn't include anyone older than their mid-30s.

The findings could improve design of high-footfall spaces like airports and museums, and may sharpen emergency evacuation planning as well.

There's no apparent practical reason for our feet to turn, yet here most of us are, veering left.

Hot Take: It's hard to not feel like a bit of a Muppet when there's an unknown force tugging your strings just a little to the left. The open question is does the steering ever straighten out?
