‘Dr. Iñaki Echeverría-Huarte is a professor of applied physics at the University of Navarra in Spain. He asked 573 people assembled in a schoolyard to roam randomly through the space. Within a few seconds, 80% of them were moving in a counterclockwise direction.

Was this because of a perceived group preference? No. Dr. Echeverría-Huarte performed the test on solitary participants, and about 75% of them moved counterclockwise. This trend persisted across 40 experiments.

A recent article in the New York Times explores the phenomenon and its potential causes. It’s clear that left or right-handedness does not correlate with this movement. Nor is it socially conditioned, as young children strongly exhibit counterclockwise movement as well as adults.

Whatever might be the root cause the movement, it will be helpful for architects and other professions that make use of crowd dynamics. I occasionally visit the largest convenience store in the world, which is a masterpiece of architecture designed for crowd movement. An awareness of the counterclockwise tendency could optimize such designs….’ (John Farrier via Neatorama)
