Opinions on Abortion as Measured by the Lost-Letter Technique
Phillip R. Kunz, Robert M. Fernquist · Psychological Reports · 1989
This study uses a postal card as a modification of the "lost letter" technique to obtain information about abortion attitudes. The message on the cards (which can be read easily by the finder) included 100 with a promise to donate money to a proabortion committee, 100 to an antiabortion committee, and 100 contained a neutral message having nothing to do with abortion. 50 of each type of card were dropped in one of two urban areas. There were more antiabortion than proabortion cards mailed, but the highest return rate of neutral cards suggests a need for additional study of abortion attitudes.
