Although North American college undergraduates make up only about 0.2 percent of the world's population, they account for a massively disproportionate number of psychology research subjects. In 2008, psychologist Jeffrey Arnett reported that in major social and personality journals, 67 to 80 percent of samples are comprised of college undergraduates. In fact, a college student in this country is 4,000 times as likely to be a psychology research subject than almost anyone else in the world.

University of British Columbia psychologists Joseph Henrich, Steven Heine, and Ara Norenzayan note that psychology studies are by and large conducted on a WEIRD (Western, Educated, Industrialized, Rich, and Democratic) bunch.
