KATHARINA MEERUM TERWOGT-KOUWENHOVENIt was tested whether the same factors people take into account when involved in the decision to lie apply to the evaluation of lies presented in scenarios. The scenarios represented 12 different situation categories formed by the crossing of the ntotivr for lying (social. individualistic, egoistic), the relative importance of the situation (important matter, unimportant matter), and the closeness of the relation between the subject and the receiver of the lie (best friend, acquaintance). The acceptability of lying was evaluated from 2 perspectives (self, others) by 180 women of the general public. The results show that as the interest of the person that is lied to becomes greater, lying becomes more acceptable. As the interest of the liar becomes greater, lying becomes less acceptable. The systematically higher estimations of acceptability attributed to others indicate a false-uniqueness effect.The proposition that lying is to be rejected in most instances seems to be advocated not only by social scientists and philosophers (e.g., Barnes, 1994; Bok, 1978) but also by laypeople. From group interviews, conducted as a pilot study (Backbier, 1994) in order to gain a deeper insight into the way people view lying and deception in everyday life, it appeared that the interviewees reacted rather negatively to lying in general and even more negatively to other people's lies. In contrast, however, the interviewees reported many instances in which they lied themselves, and even showed a great deal of understanding for their own lies. The interviewees did not seem to be aware of having a somewhat dual 'This study was conducted as part of a research project on "lying and deception in everyday life." The authors would like to thank Monique Crooy, Jaro van der Ende, Milja Falentijn, Jutka Halberstadt, and Nieske Winters for their assistance in developing the scenarios and collecting the data.
