Altruistic Responses under Conditions of Anonymity

Summary The effect of anonymity on altruistic responding was examined by means of the “lost letter” technique Ss were 99 male drivers and 106 female drivers who parked their cars in shopping centers. A sealed letter with a note attached made it appear that someone had mistaken the S's car for the car of a person to whom the letter was addressed. The return of letters served as the measure of altruism. Contrary to previous research involving face-to-face interactions: (a) females assisted females more than males assisted females; (b) bad news was delivered sooner than good news; (c) the presence of others did not inhibit helping.
