Own-Group Bias in Survey Return Rate: An Unobtrusive Attitude Measure

A survey of racial attitudes was distributed in two predominantly white neighborhoods differing in median income. In a 15.75% sample of 400 persons fewer questionnaires were returned when the surveyor (identified in an introductory paragraph) was black. In addition, subjects from the high-income neighborhood returned more surveys to a Social Scientist than to a Concerned Citizen.
