The pin prick method of secret balloting
Journal of Applied Psychology · 1947 · Volume 32 · Issue 6
Abstract
Prepare the ordinary type of question sheet, but instead of using pencils, use straight pins or toothpicks for marking where fear of disclosure or betrayal of authorship by identification of check marks is feared by the respondents. Directions tell subjects to punch one hole for a "yes" and 2 holes for "no," or deviations from this procedure may be made which are appropriate to the type of question being used.
