Rightness is big in America, suggests this study done two decades ago:
“Right-Handers and Americans Favor Turning to the Right,” Angelique A. Scharine and Michael K. McBeath, Human Factors, vol. 44, no. 2, Summer 2002, pp. 248-56. The authors, at Arizona State University, report:
“We tested a finding by E. S. Robinson (1933) that people have a bias to turn right upon entering a building. We hypothesized that this bias is attributable to learning derived from traffic rules that specify driving on the right side of the road and that it also could be related to handedness. We tested participants in both the United States and England in a simple “T-maze” task in order to compare their directional preference. Handedness was the best predictor of participants’ directional preference. However, U.S. participants also were statistically more likely to turn right than were English participants. The preference to turn right was not found to be significantly related to eye dominance or reading direction of the primary written language of the participant, although in the case of reading direction, the sample size of right-to-left readers was too small to be conclusive.”
