🌅 Humans Prefer Turning Left When Walking

WHAT TO KNOW

• A chance discovery by researchers in Spain and Japan has uncovered what may ultimately be regarded as a near-universal human preference: we like to turn left when we walk. In 32 out of 33 experiments, researchers found study participants noticeably preferred to turn counterclockwise when roaming about at will, regardless of whether they were moving as part of a crowd (80% of participants prefer to turn left) or alone (75%). Understanding the preference could help make crowds and evacuation situations safer, and help guide the design of everyday spaces, like supermarkets, museums, or train stations.

WHY IT MATTERS

• As to what’s driving the phenomenon, the researchers don’t have a clue. After five years of testing different factors, including individual preferences, group dynamics, and changes to room layouts, the team has exhausted most of their hypotheses and says they’re no closer to discovering what’s actually driving the apparent preference (though they’re certain it’s driven by individual preference and not collective utility or need). The accidental discovery was made while researchers were investigating COVID-era social distancing protocols and whether people maintained sufficient distance while walking.

CONNECT THE DOTS

• Humans’ preference for counterclockwise turns can be seen throughout the world of sports, where track athletes, horses, motorsports racers, speed skaters, cyclists, and even baseball players all follow the same path. During the first three modern Olympics in 1896, 1900, and 1904, athletes actually ran clockwise around the track, however, the setup was changed in 1908 to the current “left-hand inside” (i.e., counterclockwise) system after athletes complained. The International Olympic Committee formally adopted the change in 1913 and nearly all track athletes around the world have run counterclockwise ever since.
