tele-phonies

Of the telephone conversations, 37 percent involved deception, while face-to-face conversations included lies 27 percent of the time. About 21 percent of the instant messages and 14 percent of the e-mailing included lies. Hancock also found that experienced e-mail users were more likely to lie more often. (emph mine)
