In 2 diary studies of lying, 77 college students reported telling 2 lies a day, and 70 community members told 1. Participants told more self-centered lies than other-oriented lies, except in dyads involving only women, in which other-oriented lies were as common as self-centered ones. Participants told relatively more self-centered lies to men and relatively more other-oriented lies to women. Consistent with the view of lying as an everyday social interaction process, participants said that they did not regard their lies as serious and did not plan them much or worry about being caught. Still, social interactions in which lies were told were less pleasant and less intimate than those in which no lies were told. Although psychologists of many orientations have had. much to say about lying (DePaulo, Stone, & Lassiter, 1985; Ford, King, & Hollender, 1988; Lewis & Saarni, 1993), the topic is hardly their exclusive domain. Interest in lying transcends most disciplinary, cultural, and historical boundaries. Analyses of lying appear in religious treatises, staid textbooks, and irreverent tabloids. Perspectives on lying are as diverse as their sources. Lying has been described as a threat to the moral fabric of society (Bok, 1978), a predictor of dire life outcomes (Stouthamer-Loeber, 1986), asocial skill (DePaulo & Jordan, 1982;Nyberg, 1993), and an important developmental milestone (deVilliers &deVilliers, 1978). Pronouncements about deceit are staggeringly varied not only because of the nature of the beast, but also because the debate on deceit has in some important ways proceeded virtually unconstrained by data. Many perspectives on deceit rest on assumptions about patterns of lying in everyday life. However, some of the most fundamental questions about everyday lies
